"""Perf annotate for JIT code.
Linux `perf annotate` does not work with JIT code. This script takes the data
produced by `perf script` command, plus the diassemblies outputed by gallivm
into /tmp/perf-XXXXX.map.asm and produces output similar to `perf annotate`.
See docs/llvmpipe.html for usage instructions.
The `perf script` output parser was derived from the gprof2dot.py script.

OpenGL Core and Compatibility context support
OpenGL 3.1 and later versions are only supported with the Core profile.
There are no plans to support GL_ARB_compatibility. The last supported OpenGL
version with all deprecated features is 3.0. Some of the later GL features
are exposed in the 3.0 context as extensions.

Mesa Cygwin/X11 Information
WARNING
=======
If you installed X11 (packages xorg-x11-devel and xorg-x11-bin-dlls ) with the
latest setup.exe from Cygwin the GL (Mesa) libraries and include are already
installed in /usr/X11R6.
The following will explain how to "replace" them.
Installation
============
How to compile Mesa on Cygwin/X11 systems:
1. Shared libs:
type 'make cygwin-sl'.
When finished, the Mesa DLL will be in the Mesa-x.y/lib/ and
Mesa-x.y/bin directories.
2. Static libs:
type 'make cygwin-static'.
When finished, the Mesa libraries will be in the Mesa-x.y/lib/ directory.
Header and library files:
After you've compiled Mesa and tried the demos I recommend the following
procedure for "installing" Mesa.
Copy the Mesa include/GL directory to /usr/X11R6/include:
cp -a include/GL /usr/X11R6/include
Copy the Mesa library files to /usr/X11R6/lib:
cp -a lib/* /usr/X11R6ocal/lib
Copy the Mesa bin files (used by the DLL stuff) to /usr/X11R6/bin:
cp -a lib/cyg* /usr/X11R6/bin
Xt/Motif widgets:
If you want to use Mesa or OpenGL in your Xt/Motif program you can build
the widgets found in either the widgets-mesa or widgets-sgi directories.
The former were written for Mesa and the later are the original SGI
widgets. Look in those directories for more information.
For the Motif widgets you must have downloaded the lesstif package.
Using the library
=================
Configuration options:
The file src/mesa/main/config.h has many parameters which you can adjust
such as maximum number of lights, clipping planes, maximum texture size,
etc. In particular, you may want to change DEPTH_BITS from 16 to 32
if a 16-bit depth buffer isn't precise enough for your application.
Shared libraries:
If you compile shared libraries (Win32 DLLS) you may have to set an
environment variable to specify where the Mesa libraries are located.
Set the PATH variable to include /your-dir/Mesa-2.6/bin.
Otherwise, when you try to run a demo it may fail with a message saying
that one or more DLL couldn't be found.
Xt/Motif Widgets:
Two versions of the Xt/Motif OpenGL drawing area widgets are included:
widgets-sgi/ SGI's stock widgets
widgets-mesa/ Mesa-tuned widgets
Look in those directories for details
Togl:
Togl is an OpenGL/Mesa widget for Tcl/Tk.
See http://togl.sourceforge.net for more information.
X Display Modes:
Mesa supports RGB(A) rendering into almost any X visual type and depth.
The glXChooseVisual function tries its best to pick an appropriate visual
for the given attribute list. However, if this doesn't suit your needs
you can force Mesa to use any X visual you want (any supported by your
X server that is) by setting the MESA_RGB_VISUAL and MESA_CI_VISUAL
environment variables. When an RGB visual is requested, glXChooseVisual
will first look if the MESA_RGB_VISUAL variable is defined. If so, it
will try to use the specified visual. Similarly, when a color index
visual is requested, glXChooseVisual will look for the MESA_CI_VISUAL
variable.
The format of accepted values is: <visual-class> <depth>
Here are some examples:
using the C-shell:
% setenv MESA_RGB_VISUAL "TrueColor 8" // 8-bit TrueColor
% setenv MESA_CI_VISUAL "PseudoColor 12" // 12-bit PseudoColor
% setenv MESA_RGB_VISUAL "PseudoColor 8" // 8-bit PseudoColor
using the KornShell:
$ export MESA_RGB_VISUAL="TrueColor 8"
$ export MESA_CI_VISUAL="PseudoColor 12"
$ export MESA_RGB_VISUAL="PseudoColor 8"
Double buffering:
Mesa can use either an X Pixmap or XImage as the backbuffer when in
double buffer mode. Using GLX, the default is to use an XImage. The
MESA_BACK_BUFFER environment variable can override this. The valid
values for MESA_BACK_BUFFER are: Pixmap and XImage (only the first
letter is checked, case doesn't matter).
A pixmap is faster when drawing simple lines and polygons while an
XImage is faster when Mesa has to do pixel-by-pixel rendering. If you
need depth buffering the XImage will almost surely be faster. Exper-
iment with the MESA_BACK_BUFFER variable to see which is faster for
your application.
Colormaps:
When using Mesa directly or with GLX, it's up to the application writer
to create a window with an appropriate colormap. The aux, tk, and GLUT
toolkits try to minimize colormap "flashing" by sharing colormaps when
possible. Specifically, if the visual and depth of the window matches
that of the root window, the root window's colormap will be shared by
the Mesa window. Otherwise, a new, private colormap will be allocated.
When sharing the root colormap, Mesa may be unable to allocate the colors
it needs, resulting in poor color quality. This can happen when a
large number of colorcells in the root colormap are already allocated.
To prevent colormap sharing in aux, tk and GLUT, define the environment
variable MESA_PRIVATE_CMAP. The value isn't significant.
Gamma correction:
To compensate for the nonlinear relationship between pixel values
and displayed intensities, there is a gamma correction feature in
Mesa. Some systems, such as Silicon Graphics, support gamma
correction in hardware (man gamma) so you won't need to use Mesa's
gamma facility. Other systems, however, may need gamma adjustment
to produce images which look correct. If in the past you thought
Mesa's images were too dim, read on.
Gamma correction is controlled with the MESA_GAMMA environment
variable. Its value is of the form "Gr Gg Gb" or just "G" where
Gr is the red gamma value, Gg is the green gamma value, Gb is the
blue gamma value and G is one gamma value to use for all three
channels. Each value is a positive real number typically in the
range 1.0 to 2.5. The defaults are all 1.0, effectively disabling
gamma correction. Examples using csh:
% setenv MESA_GAMMA "2.3 2.2 2.4" // separate R,G,B values
% setenv MESA_GAMMA "2.0" // same gamma for R,G,B
The demos/gamma.c program may help you to determine reasonable gamma
value for your display. With correct gamma values, the color intensities
displayed in the top row (drawn by dithering) should nearly match those
in the bottom row (drawn as grays).
Alex De Bruyn reports that gamma values of 1.6, 1.6 and 1.9 work well
on HP displays using the HP-ColorRecovery technology.
Mesa implements gamma correction with a lookup table which translates
a "linear" pixel value to a gamma-corrected pixel value. There is a
small performance penalty. Gamma correction only works in RGB mode.
Also be aware that pixel values read back from the frame buffer will
not be "un-corrected" so glReadPixels may not return the same data
drawn with glDrawPixels.
For more information about gamma correction see:
http://www.inforamp.net/~poynton/notes/colour_and_gamma/GammaFAQ.html
Overlay Planes
Overlay planes in the frame buffer are supported by Mesa but require
hardware and X server support. To determine if your X server has
overlay support you can test for the SERVER_OVERLAY_VISUALS property:
xprop -root | grep SERVER_OVERLAY_VISUALS
HPCR glClear(GL_COLOR_BUFFER_BIT) dithering
If you set the MESA_HPCR_CLEAR environment variable then dithering
will be used when clearing the color buffer. This is only applicable
to HP systems with the HPCR (Color Recovery) system.
Extensions
==========
There are three Mesa-specific GLX extensions at this time.
GLX_MESA_pixmap_colormap
This extension adds the GLX function:
GLXPixmap glXCreateGLXPixmapMESA( Display *dpy, XVisualInfo *visual,
Pixmap pixmap, Colormap cmap )
It is an alternative to the standard glXCreateGLXPixmap() function.
Since Mesa supports RGB rendering into any X visual, not just True-
Color or DirectColor, Mesa needs colormap information to convert RGB
values into pixel values. An X window carries this information but a
pixmap does not. This function associates a colormap to a GLX pixmap.
See the xdemos/glxpixmap.c file for an example of how to use this
extension.
GLX_MESA_release_buffers
Mesa associates a set of ancillary (depth, accumulation, stencil and
alpha) buffers with each X window it draws into. These ancillary
buffers are allocated for each X window the first time the X window
is passed to glXMakeCurrent(). Mesa, however, can't detect when an
X window has been destroyed in order to free the ancillary buffers.
The best it can do is to check for recently destroyed windows whenever
the client calls the glXCreateContext() or glXDestroyContext()
functions. This may not be sufficient in all situations though.
The GLX_MESA_release_buffers extension allows a client to explicitly
deallocate the ancillary buffers by calling glxReleaseBuffersMESA()
just before an X window is destroyed. For example:
#ifdef GLX_MESA_release_buffers
glXReleaseBuffersMESA( dpy, window );
#endif
XDestroyWindow( dpy, window );
This extension is new in Mesa 2.0.
GLX_MESA_copy_sub_buffer
This extension adds the glXCopySubBufferMESA() function. It works
like glXSwapBuffers() but only copies a sub-region of the window
instead of the whole window.
This extension is new in Mesa version 2.6
Summary of X-related environment variables:
MESA_RGB_VISUAL - specifies the X visual and depth for RGB mode (X only)
MESA_CI_VISUAL - specifies the X visual and depth for CI mode (X only)
MESA_BACK_BUFFER - specifies how to implement the back color buffer (X only)
MESA_PRIVATE_CMAP - force aux/tk libraries to use private colormaps (X only)
MESA_GAMMA - gamma correction coefficients (X only)

Mesa 3.0 MITS Information
This software is distributed under the terms of the GNU Library
General Public License, see the LICENSE file for details.
This document is a preliminary introduction to help you get
started. For more detaile information consult the web page.
http://10-dencies.zkm.de/~mesa/
Version 0.1 (Yes it's very alpha code so be warned!)
Contributors:
Emil Briggs (briggs@bucky.physics.ncsu.edu)
David Bucciarelli (tech.hmw@plus.it)
Andreas Schiffler (schiffler@zkm.de)
1. Requirements:
Mesa 3.0.
An SMP capable machine running Linux 2.x
libpthread installed on your machine.
2. What does MITS stand for?
MITS stands for Mesa Internal Threading System. By adding
internal threading to Mesa it should be possible to improve
performance of OpenGL applications on SMP machines.
3. Do applications have to be recoded to take advantage of MITS?
No. The threading is internal to Mesa and transparent to
applications.
4. Will all applications benefit from the current implementation of MITS?
No. This implementation splits the processing of the vertex buffer
over two threads. There is a certain amount of overhead involved
with the thread synchronization and if there is not enough work
to be done the extra overhead outweighs any speedup from using
dual processors. You will not for example see any speedup when
running Quake because it uses GL_POLYGON and there is only one
polygon for each vertex buffer processed. Test results on a
dual 200 Mhz. Pentium Pro system show that one needs around
100-200 vertices in the vertex buffer before any there is any
appreciable benefit from the threading.
5. Are there any parameters that I can tune to try to improve performance.
Yes. You can try to vary the size of the vertex buffer which is
define in VB_MAX located in the file src/vb.h from your top level
Mesa distribution. The number needs to be a multiple of 12 and
the optimum value will probably depend on the capabilities of
your machine and the particular application you are running.
6. Are there any ways I can modify the application to improve its
performance with the MITS?
Yes. Try to use as many vertices between each Begin/End pair
as possbile. This will reduce the thread synchronization
overhead.
7. What sort of speedups can I expect?
On some benchmarks performance gains of up to 30% have been
observerd. Others may see no gain at all and in a few rare
cases even some degradation.
8. What still needs to be done?
Lots of testing and benchmarking.
A portable implementation that works within the Mesa thread API.
Threading of additional areas of Mesa to improve performance
even more.
Installation:
1. This assumes that you already have a working Mesa 3.0 installation
from source.
2. Place the tarball MITS.tar.gz in your top level Mesa directory.
3. Unzip it and untar it. It will replace the following files in
your Mesa source tree so back them up if you want to save them.
README.MITS
Make-config
Makefile
mklib.glide
src/vbxform.c

Info on using Mesa 3.0 with Linux Quake I and Quake II
Disclaimer
----------
I am _not_ a Quake expert by any means. I pretty much only run it to
test Mesa. There have been a lot of questions about Linux Quake and
Mesa so I'm trying to provide some useful info here. If this file
doesn't help you then you should look elsewhere for help. The Mesa
mailing list or the news://news.3dfx.com/3dfx.linux.glide newsgroup
might be good.
Again, all the information I have is in this file. Please don't email
me with questions.
If you have information to contribute to this file please send it to
me at brianp@elastic.avid.com
Linux Quake
-----------
You can get Linux Quake from http://www.idsoftware.com/
Quake I and II for Linux were tested with, and include, Mesa 2.6. You
shouldn't have too many problems if you simply follow the instructions
in the Quake distribution.
RedHat 5.0 Linux problems
-------------------------
RedHat Linux 5.x uses the GNU C library ("glibc" or "libc6") whereas
previous RedHat and other Linux distributions use "libc5" for its
runtime C library.
Linux Quake I and II were compiled for libc5. If you compile Mesa
on a RedHat 5.x system the resulting libMesaGL.so file will not work
with Linux Quake because of the different C runtime libraries.
The symptom of this is a segmentation fault soon after starting Quake.
If you want to use a newer version of Mesa (like 3.x) with Quake on
RedHat 5.x then read on.
The solution to the C library problem is to force Mesa to use libc5.
libc5 is in /usr/i486-linux-libc5/lib on RedHat 5.x systems.
Emil Briggs (briggs@tick.physics.ncsu.edu) nicely gave me the following
info:
> I only know what works on a RedHat 5.0 distribution. RH5 includes
> a full set of libraries for both libc5 and glibc. The loader ld.so
> uses the libc5 libraries in /usr/i486-linux-libc5/lib for programs
> linked against libc5 while it uses the glibc libraries in /lib and

I've already patched the mklib.glide file. You'll have to start Quake
with the script shown above though.

Here's my thoughts on the problem. On a RH 5.x system, you can NOT build
a libc5 executable or library. Red Hat just doesn't include the right
stuff to do it.
Since Quake is a libc5 based application, you are in trouble. You need
libc5 libraries.
What can you do about it? Well there's a package called gcc5 that does
MOST of the right stuff to compile with libc5. (It brings back older
header files, makes appropriate symbolic links for libraries, and sets
up the compiler to use the correct directories) You can find gcc5 here:
ftp://ecg.mit.edu/pub/linux/gcc5-1.0-1.i386.rpm
No, this isn't quite enough. There are still a few tricks to getting
Mesa to compile as a libc5 application. First you have to make sure that
every compile uses gcc5 instead of gcc. Second, in some cases the link
line actually lists -L/usr/lib which breaks gcc5 (because it forces you
to use the glibc version of things)
If you get all the stuff correctly compiled with gcc5 it should work.
I've run Mesa 3.0B6 and its demos in a window with my Rush on a Red Hat
5.1 system. It is a big hassle, but it can be done. I've only made Quake
segfault, but I think that's from my libRush using the wrong libc.
Yes, mixing libc5 and glibc is a major pain. I've been working to get
all my libraries compiling correctly with this setup. Someone should
make an RPM out of it and feed changes back to Brian once they get it
all working. If no one else has done so by the time I get the rest of my
stuff straightened out, I'll try to do it myself.

Mesa Threads README
-------------------
Thread safety was introduced in Mesa 2.6 by John Stone and
Christoph Poliwoda.
It was redesigned in Mesa 3.3 so that thread safety is
supported by default (on systems which support threads,
that is). There is no measurable penalty on single
threaded applications.
NOTE that the only _driver_ which is thread safe at this time
is the OS/Mesa driver!
At present the mthreads code supports three thread APIS:
1) POSIX threads (aka pthreads).
2) Solaris / Unix International threads.
3) Win32 threads (Win 95/NT).
Support for other thread libraries can be added src/glthread.[ch]
In order to guarantee proper operation, it is
necessary for both Mesa and application code to use the same threads API.
So, if your application uses Sun's thread API, then you should build Mesa
using one of the targets for Sun threads.
The mtdemos directory contains some example programs which use
multiple threads to render to osmesa rendering context(s).
Linux users should be aware that there exist many different POSIX
threads packages. The best solution is the linuxthreads package
(http://pauillac.inria.fr/~xleroy/linuxthreads/) as this package is the
only one that really supports multiprocessor machines (AFAIK). See
http://pauillac.inria.fr/~xleroy/linuxthreads/README for further
information about the usage of linuxthreads.
If you are interested in helping with thread safety work in Mesa
join the Mesa developers mailing list and post your proposal.
Regards,
John Stone -- j.stone@acm.org johns@cs.umr.edu

VMS support contributed by Jouk Jansen (joukj@hrem.stm.tudelft.nl)
The latest version was tested on a VMSAlpha7.2 system using DECC6.0, but
probably also works for other versions.
At the moment only the libraries LIBMESGL.EXE/LIBMESGL.OLB,
LIBMESAGLU.EXE/LIBMESAGLU.OLB and LIBGLUT.EXE/LIBGLUT.OLB and the demos of the
directory [.DEMOS] can be build.
However, feel free to create the missing "decrip.mms-files" in the other
directories.
The make files were tested
using the DIGITAL make utility called MMS. There is also a public domain
clone available (MMK) and I think, but it is not tested, that this
utility will give (hardly) any problem.
To make everything just type MMS (or MMK) in the main directory of
mesagl. For MMS the deafult makefile is called descrip.mms, and
that is what I have called it. I included alse some config files,
all having mms somewhere in the name which all the makefiles need
(just as your unix makefiles).
On Alpha platforms at default a sharable images for the libraries are created.
To get a static library make it by typing MMS/MACRO=(NOSHARE=1).
On VAX platforms only static libraries can be build.
23-sep-2005
changed default compilation to use /float=ieee/ieee=denorm. The reason for
this is that it makes Mesa on OpenVMS better compatible with other platforms
and other packages for VMS that I maintain.
For more information see
http://nchrem.tnw.tudelft.nl/openvms
https://bugs.freedesktop.org/show_bug.cgi?id=4270
You may want to compile Mesa to use VAX-floating point arithmetic, instead
of IEEE floating point by removing the /float=IEEE/denorm flag from the
compiler options in the descrip.mms files.

Mesa 5.1 release notes
December 17, 2003
PLEASE READ!!!!
Introduction
------------
Mesa uses an even/odd version number scheme like the Linux kernel.
Even-numbered versions (such as 5.0) designate stable releases.
Odd-numbered versions (such as 5.1) designate new developmental releases.
Bug fixes
---------
See the VERSIONS file for a list of bugs fixed in this release.
New Features in Mesa 5.1
------------------------
GL_ARB_vertex_program / GL_ARB_fragment_program
Michal Krol and Karl Rasche implemented these extensions. Thanks!
Be aware that there may be some rough edges and lurking bugs.
GL_ATI_texture_env_combine3 extension
This adds a few new texture combine modes.
Contributed by Ian Romanick.
GL_SGI_texture_color_table
Adds a color table lookup to the RGBA texture path. There's a separate
color table for each texture unit.
Contributed by Eric Plante.
GL_NV_fragment_program
NVIDIA's fragment-level programming feature.
Possible lurking bugs:
- the DDX and DDY commands aren't fully tested
- there may be bugs in the parser
- the TEX and TXP instructions both do perspective correction
- the pack/unpack instructions may not be correct
GL_EXT_depth_bounds_test
This extension adds a scissor-like test for the Z axis. It's used to
optimize stencil-volume shadow algorithms.
GL_NV_light_max_exponent
Lifts the 128 limit for max light exponent.
GL_EXT_texture_rectangle
Identical to GL_NV_texture_rectangle
GL_ARB_occlusion_query
Useful for visibility-based culling.
GL_ARB_texture_non_power_of_two
Removes the restriction that texture dimensions must be powers of two.
GL_ARB_vertex_buffer_object
Allows server-side vertex arrays, optimized host/card data transfers, etc.
GL_ARB_point_sprite
ARB-approved version of GL_NV_point_sprite. Basically allows textures
to be applied to points.
GL_IBM_multimode_draw_arrays
Allows multiple vertex arrays to be drawn with one call, including arrays
of different types of primitives.
GL_SUN_multi_draw_arrays
An alias for GL_EXT_multi_draw_arrays, standard in OpenGL 1.4.
Faster glDrawPixels / glCopyPixels in X11 driver
If your X screen is 32bpp, glDrawPixels to the front color buffer will
be accelerated (via XPutImage()) if the image format is GL_BGRA and the
type is GL_UNSIGNED_BYTE. No raster operations, such as depth test,
blend, fog, etc. can be enabled.
If your X screen is 16bpp, glDrawPixels to the front color buffer will
be accelerated (via XPutImage()) if the image format is GL_RGB and the
type is GL_UNSIGNED_SHORT_5_6_5. No raster operations, such as depth
test, blend, fog, etc. can be enabled.
glCopyPixels() calls for the front color buffer will be accelerated
(via XCopyArea()) if no raster operations, such as depth test, blend,
fog, pixel zoom, etc. are enabled.
The speed-up over typical software rendering is a factor of 10 for
glDrawPixels and 100 for glCopyPixels.
With the addition of GL_ARB_occlusion_query, GL_ARB_vertex_buffer_object,
GL_ARB_texture_non_power_of_two and GL_EXT_shadow_funcs, Mesa 5.1 supports
all the new features of OpenGL 1.5. Mesa 6.0 (the next stable release)
will advertise GL_VERSION = "1.5".
Vertex/Fragment program debugger
--------------------------------
GL_MESA_program_debug is an experimental extension to support
interactive debugging of vertex and fragment programs. See the
docs/MESA_program_debug.spec file for details.
The bulk of the vertex/fragment program debugger is implemented
outside of Mesa. The GL_MESA_program_debug extension just has minimal
hooks for stopping running programs and inspecting programs.
The progs/tests/debugger.c (only in CVS) program is an example of how
the extension can be used. Presently, the debugger code and demo code
is in the same file. Eventually the debugger code should be moved
into a reusable module.
As it is now, the demo lets you set breakpoings in vertex/fragment
programs, single step, and print intermediate register values. It's
basically just a proof of concept.
Directory tree reorganization
-----------------------------
The directory structure for Mesa has been overhauled to improve its layout.
All source code for Mesa, GLU, GLUT, etc is now under the src/ directory
in appropriate subdirectories.
The Mesa source code and drivers has been reorganized under src/mesa/.
All demonstration programs and tests are now in subdirectories under progs/.
Build System Changes
--------------------
The GNU automake/autoconf support has been removed. As it was, it seldom
worked on anything but Linux. The Mesa developers aren't big fans of
automake/autoconf/libtool and didn't have the time to maintain it.
If someone wants to contribute new automake/autoconf support (and is
willing to maintain it), it may be re-incorporated into Mesa, subject
to some requirements.
The "old style" makefile system has been updated:
1. Make-config has been trimmed down to fewer, modern configurations.
2. Most of the bin/mklib.* scripts have been rolled into a new "mklib"
script that works on all sorts of systems. There are probably some
bugs in it, but it's been tested on Linux, SunOS 5.8 and IRIX 6.5.
Improvements/contributes are greatly appreciated.
3. The Makefile.X11 files have been cleaned up in various ways
Source File Changes
-------------------
The mmath.[ch] files are obsolete. Their contents have been moved
into the imports.[ch] and macros.[ch] files.
The files related to vertex and fragment programming have changed.
Old files:
vpexec.[ch]
vpparse.[ch]
vpstate.[ch]
New files:
program.[ch] - generic ARB/NV program code
arbprogram.[ch] - ARB program API functions

nvvertparse.[ch] - NV vertex program parser
nvfragparse.[ch] - NV fragment program parser
nvvertexec.[ch] - NV vertex program execution

tnl/t_eval_api.c - old per-vertex code
tnl/t_imm_alloc.c - old per-vertex code
tnl/t_imm_api.c - old per-vertex code
tnl/t_imm_debug.c - old per-vertex code

Other new files:
bufferobj.[ch] - GL_ARB_vertex_buffer_object functions
version.h - defines the Mesa version info
Other removed files:
swrast/s_histogram.[ch] - moved into src/histogram.c
Other Changes
-------------
The ctx->Driver.CreateTexture function has been removed - it wasn't used.
New device driver hook functions:
NewTextureObject - used to allocate struct gl_texture_objects
NewTextureImage - used to allocate struct gl_texture_images
New ctx->Texture._EnabledCoordUnits field:
With the addition of GL_NV_fragment_program we may need to interpolate
various sets of texture coordinates even when the corresponding texture
unit is not enabled. That is, glEnable(GL_TEXTURE_xD) may never get
called but we still may have to interpolate texture coordinates across
triangles so that the fragment program will get them.
This new field indicates which sets of texture coordinates are needed.
If a bit is set in the ctx->Texture._EnabledUnits bitmask is set, the
same bit MUST be set in ctx->Texture._EnabledCoordUnits.
The ctx->_TriangleCaps field is deprecated.
Instead of testing the DD_* bits in _TriangleCaps, you should instead
directly test the relevant state variables, or use one of the helper
functions like NEED_SECONDARY_COLOR() at the bottom of context.h
While testing _TriangleCaps bits was fast, it was kludgey, and setting
the bits in the first place could be error prone.
New vertex processing code.
The code behind glBegin, glEnd, glVertex, glNormal, etc. has been
totally rewritten. It's a cleaner implementation now and should use
less memory. (Keith)
To Do
-----
Add screen-awareness to fakeglx.c
Device Driver Status
--------------------
A number of Mesa's software drivers haven't been actively maintained for
some time. We rely on volunteers to maintain many of these drivers.
Here's the current status of all included drivers:
Driver Status
---------------------- ---------------------
XMesa (Xlib) implements OpenGL 1.4
OSMesa (off-screen) implements OpenGL 1.4
FX (3dfx Voodoo1/2) implements OpenGL 1.3
SVGA implements OpenGL 1.3
Wind River UGL implements OpenGL 1.3
Windows/Win32 implements OpenGL 1.4
DJGPP implements OpenGL 1.4
GGI implements OpenGL 1.3
BeOS implements OpenGL 1.4
Allegro needs updating
D3D needs updating
Note: supporting OpenGL 1.4 (vs. 1.3 or 1.2) usually only requires that the
driver call the _mesa_enable_1_4_extensions() function.

<h1>Application Issues</h1>
<p>
This page documents known issues with some OpenGL applications.
</p>
<h2>Topogun</h2>
<p>
<a href="http://www.topogun.com/">Topogun</a> for Linux (version 2, at least)
creates a GLX visual without requesting a depth buffer.
This causes bad rendering if the OpenGL driver happens to choose a visual
without a depth buffer.
</p>
<p>
Mesa 9.1.2 and later (will) support a DRI configuration option to work around
this issue.
Using the <a href="http://dri.freedesktop.org/wiki/DriConf">driconf</a> tool,
set the "Create all visuals with a depth buffer" option before running Topogun.
Then, all GLX visuals will be created with a depth buffer.
</p>
<h2>Old OpenGL games</h2>
<p>
Some old OpenGL games (approx. ten years or older) may crash during
start-up because of an extension string buffer-overflow problem.
</p>
<p>
The problem is a modern OpenGL driver will return a very long string
for the glGetString(GL_EXTENSIONS) query and if the application
naively copies the string into a fixed-size buffer it can overflow the
buffer and crash the application.
</p>
<p>
The work-around is to set the MESA_EXTENSION_MAX_YEAR environment variable
to the approximate release year of the game.
This will cause the glGetString(GL_EXTENSIONS) query to only report extensions
older than the given year.
</p>
<p>
For example, if the game was released in 2001, do
<pre>
export MESA_EXTENSION_MAX_YEAR=2001
</pre>
before running the game.

<li><a href="#submitting">Submitting Patches</a>
<li><a href="#release">Making a New Mesa Release</a>
<li><a href="#extensions">Adding Extensions</a>
</ul>
<h2 id="style">Coding Style</h2>
<p>
Mesa is over 20 years old and the coding style has evolved over time.
Some old parts use a style that's a bit out of date.
If the guidelines below don't cover something, try following the format of
existing, neighboring code.
</p>
<p>
Basic formatting guidelines
</p>
<ul>
<li>3-space indentation, no tabs.
<li>Limit lines to 78 or fewer characters. The idea is to prevent line
wrapping in 80-column editors and terminals. There are exceptions, such
as if you're defining a large, static table of information.
<li>Opening braces go on the same line as the if/for/while statement.
For example:
<pre>
if (condition) {
foo;
} else {
bar;
}
</pre>
<li>Put a space before/after operators. For example, <tt>a = b + c;</tt>
and not <tt>a=b+c;</tt>
<li>This GNU indent command generally does the right thing for formatting:
<pre>
indent -br -i3 -npcs --no-tabs infile.c -o outfile.c
</pre>
<li>Use comments wherever you think it would be helpful for other developers.
Several specific cases and style examples follow. Note that we roughly
follow <a href="http://www.stack.nl/~dimitri/doxygen/">Doxygen</a> conventions.
<br>
<br>
Single-line comments:
<pre>
/* null-out pointer to prevent dangling reference below */
bufferObj = NULL;
</pre>
Or,
<pre>
bufferObj = NULL; /* prevent dangling reference below */
</pre>
Multi-line comment:
<pre>
/* If this is a new buffer object id, or one which was generated but
* never used before, allocate a buffer object now.
*/
</pre>
We try to quote the OpenGL specification where prudent:
<pre>
/* Page 38 of the PDF of the OpenGL ES 3.0 spec says:
*
* "An INVALID_OPERATION error is generated for any of the following
* conditions:
*
* * <length> is zero."
*
* Additionally, page 94 of the PDF of the OpenGL 4.5 core spec
* (30.10.2014) also says this, so it's no longer allowed for desktop GL,
* either.
*/
</pre>
Function comment example:
<pre>
/**
* Create and initialize a new buffer object. Called via the
* ctx->Driver.CreateObject() driver callback function.
* \param name integer name of the object
* \param type one of GL_FOO, GL_BAR, etc.
* \return pointer to new object or NULL if error
*/
struct gl_object *
_mesa_create_object(GLuint name, GLenum type)
{
/* function body */
}
</pre>
<li>Put the function return type and qualifiers on one line and the function
name and parameters on the next, as seen above. This makes it easy to use
<code>grep ^function_name dir/*</code> to find function definitions. Also,
the opening brace goes on the next line by itself (see above.)
<li>Function names follow various conventions depending on the type of function:
<pre>
glFooBar() - a public GL entry point (in glapi_dispatch.c)
_mesa_FooBar() - the internal immediate mode function
save_FooBar() - retained mode (display list) function in dlist.c
foo_bar() - a static (private) function
_mesa_foo_bar() - an internal non-static Mesa function
</pre>
<li>Constants, macros and enumerant names are ALL_UPPERCASE, with _ between
words.
<li>Mesa usually uses camel case for local variables (Ex: "localVarname")
while gallium typically uses underscores (Ex: "local_var_name").
<li>Global variables are almost never used because Mesa should be thread-safe.
<li>Booleans. Places that are not directly visible to the GL API
should prefer the use of <tt>bool</tt>, <tt>true</tt>, and
<tt>false</tt> over <tt>GLboolean</tt>, <tt>GL_TRUE</tt>, and
<tt>GL_FALSE</tt>. In C code, this may mean that
<tt>#include &lt;stdbool.h&gt;</tt> needs to be added. The
<tt>try_emit_</tt>* methods in src/mesa/program/ir_to_mesa.cpp and
src/mesa/state_tracker/st_glsl_to_tgsi.cpp can serve as examples.
</ul>
<h2 id="submitting">Submitting patches</h2>
<p>
The basic guidelines for submitting patches are:
</p>
<ul>
<li>Patches should be sufficiently tested before submitting.
<li>Code patches should follow Mesa coding conventions.
<li>Whenever possible, patches should only effect individual Mesa/Gallium
components.
<li>Patches should never introduce build breaks and should be bisectable (see
<code>git bisect</code>.)
<li>Patches should be properly formatted (see below).
<li>Patches should be submitted to mesa-dev for review using
<code>git send-email</code>.
<li>Patches should not mix code changes with code formatting changes (except,
perhaps, in very trivial cases.)
</ul>
<h3>Patch formatting</h3>
<p>
The basic rules for patch formatting are:
</p>
<ul>
<li>Lines should be limited to 75 characters or less so that git logs
displayed in 80-column terminals avoid line wrapping. Note that git
log uses 4 spaces of indentation (4 + 75 &lt; 80).
<li>The first line should be a short, concise summary of the change prefixed
with a module name. Examples:
<pre>
mesa: Add support for querying GL_VERTEX_ATTRIB_ARRAY_LONG
gallium: add PIPE_CAP_DEVICE_RESET_STATUS_QUERY
i965: Fix missing type in local variable declaration.
</pre>
<li>Subsequent patch comments should describe the change in more detail,
if needed. For example:
<pre>
i965: Remove end-of-thread SEND alignment code.
This was present in Eric's initial implementation of the compaction code
for Sandybridge (commit 077d01b6). There is no documentation saying this
is necessary, and removing it causes no regressions in piglit on any
platform.
</pre>
<li>A "Signed-off-by:" line is not required, but not discouraged either.
<li>If a patch address a bugzilla issue, that should be noted in the
patch comment. For example:
<pre>
Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=89689
</pre>
<li>If there have been several revisions to a patch during the review
process, they should be noted such as in this example:
<pre>
st/mesa: add ARB_texture_stencil8 support (v4)
if we support stencil texturing, enable texture_stencil8
there is no requirement to support native S8 for this,
the texture can be converted to x24s8 fine.
v2: fold fixes from Marek in:
a) put S8 last in the list
b) fix renderable to always test for d/s renderable
fixup the texture case to use a stencil only format
for picking the format for the texture view.
v3: hit fallback for getteximage
v4: put s8 back in front, it shouldn't get picked now (Ilia)
</pre>
<li>If someone tested your patch, document it with a line like this:
<pre>
Tested-by: Joe Hacker &lt;jhacker@foo.com&gt;
</pre>
<li>If the patch was reviewed (usually the case) or acked by someone,
that should be documented with:
<pre>
Reviewed-by: Joe Hacker &lt;jhacker@foo.com&gt;
Acked-by: Joe Hacker &lt;jhacker@foo.com&gt;
</pre>
</ul>
<h3>Testing Patches</h3>
<p>
It should go without saying that patches must be tested. In general,
do whatever testing is prudent.
</p>
<p>
You should always run the Mesa test suite before submitting patches.
The test suite can be run using the 'make check' command. All tests
must pass before patches will be accepted, this may mean you have
to update the tests themselves.
</p>
<p>
Whenever possible and applicable, test the patch with
<a href="http://piglit.freedesktop.org">Piglit</a> to
check for regressions.
</p>
<h3>Mailing Patches</h3>
<p>
Patches should be sent to the Mesa mailing list for review.
When submitting a patch make sure to use git send-email rather than attaching
patches to emails. Sending patches as attachments prevents people from being
able to provide in-line review comments.
</p>
<p>
When submitting follow-up patches you can use --in-reply-to to make v2, v3,
etc patches show up as replies to the originals. This usually works well
when you're sending out updates to individual patches (as opposed to
re-sending the whole series). Using --in-reply-to makes
it harder for reviewers to accidentally review old patches.
</p>
<p>
When submitting follow-up patches you should also login to
<a href="https://patchwork.freedesktop.org">patchwork</a> and change the
state of your old patches to Superseded.
</p>
<h3>Reviewing Patches</h3>
<p>
When you've reviewed a patch on the mailing list, please be unambiguous
about your review. That is, state either
<pre>
Reviewed-by: Joe Hacker &lt;jhacker@foo.com&gt;
</pre>
or
<pre>
Acked-by: Joe Hacker &lt;jhacker@foo.com&gt;
</pre>
Rather than saying just "LGTM" or "Seems OK".
</p>
<p>
If small changes are suggested, it's OK to say something like:
<pre>
With the above fixes, Reviewed-by: Joe Hacker &lt;jhacker@foo.com&gt;
</pre>
which tells the patch author that the patch can be committed, as long
as the issues are resolved first.
</p>
<h3>Marking a commit as a candidate for a stable branch</h3>
<p>
If you want a commit to be applied to a stable branch,
you should add an appropriate note to the commit message.
</p>
<p>
Here are some examples of such a note:
</p>
<ul>
<li>CC: &lt;mesa-stable@lists.freedesktop.org&gt;</li>
<li>CC: "9.2 10.0" &lt;mesa-stable@lists.freedesktop.org&gt;</li>
<li>CC: "10.0" &lt;mesa-stable@lists.freedesktop.org&gt;</li>
</ul>
Simply adding the CC to the mesa-stable list address is adequate to nominate
the commit for the most-recently-created stable branch. It is only necessary
to specify a specific branch name, (such as "9.2 10.0" or "10.0" in the
examples above), if you want to nominate the commit for an older stable
branch. And, as in these examples, you can nominate the commit for the older
branch in addition to the more recent branch, or nominate the commit
exclusively for the older branch.
This "CC" syntax for patch nomination will cause patches to automatically be
copied to the mesa-stable@ mailing list when you use "git send-email" to send
patches to the mesa-dev@ mailing list. Also, if you realize that a commit
should be nominated for the stable branch after it has already been committed,
you can send a note directly to the mesa-stable@lists.freedesktop.org where
the Mesa stable-branch maintainers will receive it. Be sure to mention the
commit ID of the commit of interest (as it appears in the mesa master branch).
The latest set of patches that have been nominated, accepted, or rejected for
the upcoming stable release can always be seen on the
<a href="http://cworth.org/~cworth/mesa-stable-queue/">Mesa Stable Queue</a>
page.
<h3>Criteria for accepting patches to the stable branch</h3>
Mesa has a designated release manager for each stable branch, and the release
manager is the only developer that should be pushing changes to these
branches. Everyone else should simply nominate patches using the mechanism
described above.
The stable-release manager will work with the list of nominated patches, and
for each patch that meets the crtieria below will cherry-pick the patch with:
<code>git cherry-pick -x &lt;commit&gt;</code>. The <code>-x</code> option is
important so that the picked patch references the comit ID of the original
patch.
The stable-release manager may at times need to force-push changes to the
stable branches, for example, to drop a previously-picked patch that was later
identified as causing a regression). These force-pushes may cause changes to
be lost from the stable branch if developers push things directly. Consider
yourself warned.
The stable-release manager is also given broad discretion in rejecting patches
that have been nominated for the stable branch. The most basic rule is that
the stable branch is for bug fixes only, (no new features, no
regressions). Here is a non-exhaustive list of some reasons that a patch may
be rejected:
<ul>
<li>Patch introduces a regression. Any reported build breakage or other
regression caused by a particular patch, (game no longer work, piglit test
changes from PASS to FAIL), is justification for rejecting a patch.</li>
<li>Patch is too large, (say, larger than 100 lines)</li>
<li>Patch is not a fix. For example, a commit that moves code around with no
functional change should be rejected.</li>
<li>Patch fix is not clearly described. For example, a commit message
of only a single line, no description of the bug, no mention of bugzilla,
etc.</li>
<li>Patch has not obviously been reviewed, For example, the commit message
has no Reviewed-by, Signed-off-by, nor Tested-by tags from anyone but the
author.</li>
<li>Patch has not already been merged to the master branch. As a rule, bug
fixes should never be applied first to a stable branch. Patches should land
first on the master branch and then be cherry-picked to a stable
branch. (This is to avoid future releases causing regressions if the patch
is not also applied to master.) The only things that might look like
exceptions would be backports of patches from master that happen to look
significantly different.</li>
<li>Patch depends on too many other patches. Ideally, all stable-branch
patches should be self-contained. It sometimes occurs that a single, logical
bug-fix occurs as two separate patches on master, (such as an original
patch, then a subsequent fix-up to that patch). In such a case, these two
patches should be squashed into a single, self-contained patch for the
stable branch. (Of course, if the squashing makes the patch too large, then
that could be a reason to reject the patch.)</li>
<li>Patch includes new feature development, not bug fixes. New OpenGL
features, extensions, etc. should be applied to Mesa master and included in
the next major release. Stable releases are intended only for bug fixes.
Note: As an exception to this rule, the stable-release manager may accept
hardware-enabling "features". For example, backports of new code to support
a newly-developed hardware product can be accepted if they can be reasonably
determined to not have effects on other hardware.</li>
<li>Patch is a performance optimization. As a rule, performance patches are
not candidates for the stable branch. The only exception might be a case
where an application's performance was recently severely impacted so as to
become unusable. The fix for this performance regression could then be
considered for a stable branch. The optimization must also be
non-controversial and the patches still need to meet the other criteria of
being simple and self-contained</li>
<li>Patch introduces a new failure mode (such as an assert). While the new
assert might technically be correct, for example to make Mesa more
conformant, this is not the kind of "bug fix" we want in a stable
release. The potential problem here is that an OpenGL program that was
previously working, (even if technically non-compliant with the
specification), could stop working after this patch. So that would be a
regression that is unaacceptable for the stable branch.</li>
</ul>
<h2 id="release">Making a New Mesa Release</h2>
<p>
These are the instructions for making a new Mesa release.
</p>
<h3>Get latest source files</h3>
<p>
Use git to get the latest Mesa files from the git repository, from whatever
branch is relevant. This document uses the convention X.Y.Z for the release
being created, which should be created from a branch named X.Y.
</p>
<h3>Perform basic testing</h3>
<p>
The release manager should, at the very least, test the code by compiling it,
installing it, and running the latest piglit to ensure that no piglit tests
have regressed since the previous release.
</p>
<p>
The release manager should do this testing with at least one hardware driver,
(say, whatever is contained in the local development machine), as well as on
both Gallium and non-Gallium software drivers. The software testing can be
performed by running piglit with the following environment-variable set:
</p>
<pre>
LIBGL_ALWAYS_SOFTWARE=1
</pre>
And Gallium vs. non-Gallium software drivers can be obtained by using the
following configure flags on separate builds:
<pre>
--with-dri-drivers=swrast
--with-gallium-drivers=swrast
</pre>
<p>
Note: If both options are given in one build, both swrast_dri.so drivers will
be compiled, but only one will be installed. The following command can be used
to ensure the correct driver is being tested:
</p>
<pre>
LIBGL_ALWAYS_SOFTWARE=1 glxinfo | grep "renderer string"
</pre>
If any regressions are found in this testing with piglit, stop here, and do
not perform a release until regressions are fixed.
<h3>Update version in file VERSION</h3>
<p>
Increment the version contained in the file VERSION at Mesa's top-level, then
commit this change.
</p>
<h3>Create release notes for the new release</h3>
<p>
Create a new file docs/relnotes/X.Y.Z.html, (follow the style of the previous
release notes). Note that the sha256sums section of the release notes should
be empty at this point.
</p>
<p>
Two scripts are available to help generate portions of the release notes:
<pre>
./bin/bugzilla_mesa.sh
./bin/shortlog_mesa.sh
</pre>

</p>
<h3>Make the release archives, signatures, and the release tag</h3>
<p>
From inside the Mesa directory:
<pre>
./autogen.sh
make -j1 tarballs
</pre>
<p>
After the tarballs are created, the sha256 checksums for the files will
be computed and printed. These will be used in a step below.
</p>
<p>
It's important at this point to also verify that the constructed tar file
actually builds:
</p>
<pre>
tar xjf MesaLib-X.Y.Z.tar.bz2
cd Mesa-X.Y.Z
./configure --enable-gallium-llvm
make -j6
make install
</pre>
<p>
Some touch testing should also be performed at this point, (run glxgears or
more involved OpenGL programs against the installed Mesa).
</p>
<p>
Create detached GPG signatures for each of the archive files created above:
</p>
<pre>
gpg --sign --detach MesaLib-X.Y.Z.tar.gz
gpg --sign --detach MesaLib-X.Y.Z.tar.bz2
gpg --sign --detach MesaLib-X.Y.Z.zip
</pre>
<p>
Tag the commit used for the build:
</p>
<pre>
git tag -s mesa-X.Y.X -m "Mesa X.Y.Z release"
</pre>
<p>
Note: It would be nice to investigate and fix the issue that causes the
tarballs target to fail with multiple build process, such as with "-j4". It
would also be nice to incorporate all of the above commands into a single
makefile target. And instead of a custom "tarballs" target, we should
incorporate things into the standard "make dist" and "make distcheck" targets.
</p>
<h3>Add the sha256sums to the release notes</h3>
<p>
Edit docs/relnotes/X.Y.Z.html to add the sha256sums printed as part of "make
tarballs" in the previous step. Commit this change.
</p>
<h3>Push all commits and the tag created above</h3>
<p>
This is the first step that cannot easily be undone. The release is going
forward from this point:
</p>
<pre>
git push origin X.Y --tags
</pre>
<h3>Install the release files and signatures on the distribution server</h3>
<p>
The following commands can be used to copy the release archive files and
signatures to the freedesktop.org server:
</p>
<pre>
scp MesaLib-X.Y.Z* people.freedesktop.org:
ssh people.freedesktop.org
cd /srv/ftp.freedesktop.org/pub/mesa
mkdir X.Y.Z
cd X.Y.Z
mv ~/MesaLib-X.Y.Z* .
</pre>
<h3>Back on mesa master, add the new release notes into the tree</h3>
<p>
Something like the following steps will do the trick:
</p>
<pre>
cp docs/relnotes/X.Y.Z.html /tmp
git checkout master
cp /tmp/X.Y.Z.html docs/relnotes
git add docs/relnotes/X.Y.Z.html
</pre>
<p>
Also, edit docs/relnotes.html to add a link to the new release notes, and edit
docs/index.html to add a news entry. Then commit and push:
</p>
<pre>
git commit -a -m "docs: Import X.Y.Z release notes, add news item."
git push origin
</pre>
<h3>Update the mesa3d.org website</h3>
<p>
NOTE: The recent release managers have not been performing this step
themselves, but leaving this to Brian Paul, (who has access to the
sourceforge.net hosting for mesa3d.org). Brian is more than willing to grant
the permission necessary to future release managers to do this step on their
own.

Update the web site by copying the docs/ directory's files to
/home/users/b/br/brianp/mesa-www/htdocs/ with:

</li>
<li>
The dispatch tests check_table.cpp and dispatch_sanity.cpp
should be updated with details about the new extensions functions. These
tests are run using 'make check'
</li>
</ul>
<h2>Coding Style</h2>
<p>
Mesa's code style has changed over the years. Here's the latest.
</p>
<p>
Comment your code! It's extremely important that open-source code be
well documented. Also, strive to write clean, easily understandable code.
</p>
<p>
3-space indentation
</p>
<p>
If you use tabs, set them to 8 columns
</p>
<p>
Line width: the preferred width to fill comments and code in Mesa is 78
columns. Exceptions are sometimes made for clarity (e.g. tabular data is
sometimes filled to a much larger width so that extraneous carriage returns
don't obscure the table).
</p>
<p>
Brace example:
</p>
<pre>
if (condition) {
foo;
}
else {
bar;
}
switch (condition) {
case 0:
foo();
break;
case 1: {
...
break;
}
default:
...
break;
}
</pre>
<p>
Here's the GNU indent command which will best approximate my preferred style:
(Note that it won't format switch statements in the preferred way)
</p>
<pre>
indent -br -i3 -npcs --no-tabs infile.c -o outfile.c
</pre>
<p>
Local variable name example: localVarName (no underscores)
</p>
<p>
Constants and macros are ALL_UPPERCASE, with _ between words
</p>
<p>
Global variables are not allowed.
</p>
<p>
Function name examples:
</p>
<pre>
glFooBar() - a public GL entry point (in glapi_dispatch.c)
_mesa_FooBar() - the internal immediate mode function
save_FooBar() - retained mode (display list) function in dlist.c
foo_bar() - a static (private) function
_mesa_foo_bar() - an internal non-static Mesa function
</pre>
<p>
Places that are not directly visible to the GL API should prefer the use
of <tt>bool</tt>, <tt>true</tt>, and
<tt>false</tt> over <tt>GLboolean</tt>, <tt>GL_TRUE</tt>, and
<tt>GL_FALSE</tt>. In C code, this may mean that
<tt>#include &lt;stdbool.h&gt;</tt> needs to be added. The
<tt>try_emit_</tt>* methods in src/mesa/program/ir_to_mesa.cpp and
src/mesa/state_tracker/st_glsl_to_tgsi.cpp can serve as examples.
</p>
<h2>Making a New Mesa Release</h2>
<p>
These are the instructions for making a new Mesa release.
</p>
<h3>Get latest source files</h3>
<p>
Use git to get the latest Mesa files from the git repository, from whatever
branch is relevant.
</p>
<h3>Verify and update version info</h3>
<dl>
<dt>configs/default</dt>
<dd>MESA_MAJOR, MESA_MINOR and MESA_TINY</dd>
<dt>Makefile.am</dt>
<dd>PACKAGE_VERSION</dd>
<dt>autoconf.ac</dt>
<dd>AC_INIT</dd>
<dt>src/mesa/main/version.h</dt>
<dd>MESA_MAJOR, MESA_MINOR, MESA_PATCH and MESA_VERSION_STRING</dd>
</dl>
<p>
Create a docs/relnotes-x.y.z.html file.
The bin/shortlog_mesa.sh script can be used to create a HTML-formatted list
of changes to include in the file.
Link the new docs/relnotes-x.y.z.html file into the main <a href="relnotes.html">relnotes.html</a> file.
</p>
<p>
Update <a href="news.html">docs/news.html</a>.
</p>
<p>
Tag the files with the release name (in the form <b>mesa-x.y</b>)
with: <code>git tag -a mesa-x.y</code>
Then: <code>git push origin mesa-x.y</code>
</p>
<h3>Make the tarballs</h3>
<p>
Make the distribution files. From inside the Mesa directory:
<pre>
make tarballs
</pre>
<p>
After the tarballs are created, the md5 checksums for the files will
be computed.
Add them to the docs/relnotes-x.y.html file.
</p>
<p>
Copy the distribution files to a temporary directory, unpack them,
compile everything, and run some demos to be sure everything works.
</p>
<h3>Update the website and announce the release</h3>
<p>
Follow the directions on SourceForge for creating a new "release" and
uploading the tarballs.
</p>
<p>
Basically, to upload the tarball files with:
<br>
<code>
rsync -avP ssh Mesa*-X.Y.* USERNAME@frs.sourceforge.net:uploads/
</code>
</p>
<p>
Update the web site by copying the docs/ directory's files to
/home/users/b/br/brianp/mesa-www/htdocs/ with:
<br>
<code>
sftp USERNAME,mesa3d@web.sourceforge.net
</code>
</p>

When configuring Mesa, there are three autoconf options that affect the install
location that you should take care with: <code>--prefix</code>,
<code>--libdir</code>, and <code>--with-dri-driverdir</code>. To install Mesa
into the system location where it will be available for all programs to use, set
<code>--prefix=/usr</code>. Set <code>--libdir</code> to where your Linux
distribution installs system libraries, usually either <code>/usr/lib</code> or
<code>/usr/lib64</code>. Set <code>--with-dri-driverdir</code> to the directory
where your Linux distribution installs DRI drivers. To find your system's DRI
driver directory, try executing <code>find /usr -type d -name dri</code>. For
example, if the <code>find</code> command listed <code>/usr/lib64/dri</code>,
then set <code>--with-dri-driverdir=/usr/lib64/dri</code>.
