Ian Romanick	63ed288396	intel: Add extra, stronger flushes around CopyTexSubImage blits	2009-03-27 15:22:27 -07:00
Eric Anholt	88ce34f400	swrast: Add support for x8r8g8b8 fbconfig. This lets swrast produce an fbconfig suitable for the root visual now that the server's not allowing mismatched fbconfigs. (cherry picked from commit `529d1d720e`)	2009-03-27 15:20:09 -07:00
Ian Romanick	f535de8721	Mark current bits as 2009Q1-RC2 for Intel driver.	2009-03-26 15:32:29 -07:00
Eric Anholt	1db913f687	i965: Fix glFrontFacing in twoside GLSL demo. This also cuts instructions by just using the existing bit in the payload rather than computing it from the determinant in the SF unit and passing it as a varying down to the WM. Something still goes wrong with getting the backface color right, but a simpler shader appears to get the right result. (cherry picked from commit `699db6d842`)	2009-03-26 15:15:51 -07:00
Eric Anholt	0e5d1f43af	i965: Fix fog coordinate g,b,a values when glFrontFacing isn't used. Previously, we would sample (f,glFrontFacing,undef,undef) instead of the (f,0,0,1) that fragment.fogcoord is supposed to return. Due to glFrontFacing's presence in FOGC.y, we'll still give bad results there when glFrontFacing is used. Bug #19122, piglit testcase fp-fog. (cherry picked from commit `411d913cce`)	2009-03-26 15:15:27 -07:00
Eric Anholt	09c587ae55	i965: Clean up a bit of mess with unneeded variables in emit_interp. (cherry picked from commit `b013f945d8`)	2009-03-26 15:15:14 -07:00
