We need to perform cross-batch flushing if any batch writes to a BO
while others refer to it. We checked this case when recording a new
BO in the list which we'd never seen before. However, we neglected to
handle the case when we already read from a BO, but then began writing
to it. That new write may provoke a conflict between existing reads
in other batches, so we need to re-check the cross-batch flushing.
Caught by Piglit's copyteximage when forcing blits and copies to use
a new IRIS_BATCH_BLITTER that isn't upstream yet. But this bug could
be provoked by render/compute work today...we just hadn't noticed it.

VK CTS just added some new tests to write to a compressed image
from a compute shader, which was overrunning memory.
The image width/height need to be sized according to the block
sizes to avoid overwriting memory.

Pattern match the point coord sysval and support lowering it as well.
This is required to handle flipped framebuffers on Bifrost. However,
what this pass normalizes to is the opposite of the hardware mode we
used on Bifrost before, so we need to swap modes at the same time to
prevent regressions.

We need to guarantee that when vkQueueSubmit() returns the application
can actually wait on a signaled semaphore/syncobj.
When using a thread to do the submission to i915, this gets a bit
tricky in the following case :
A syncobj is used both as a wait & signal semaphore and has been
signaled once already. It contains a fence before entering
vkQueueSubmit().
This means we need to reset the syncobj to ensure when we return
from vkQueueSubmit(), the syncobj contains no stale fence.
Currently in the Anv, the submission thread is in charge of putting
the new fence in the syncobj and also picks up the wait fence
directly from the syncobj. This means we can't reset the syncobj
from vkQueueSubmit().
The solution to this has been pointed by Bas & Jason :
In vkQueueSubmit(), clone the wait syncobj fence into a new
temporary syncobj that will be destroy after submission and use
this temporary syncobj as a wait fence for i915. This allows us to
reset the original syncobj in vkQueueSubmit().
For this to work with wait_before_signal behavior, we also need to
do a wait-on-materialize on binary semaphores from vkQueueSubmit().
Otherwise the application thread calling vkQueueSubmit() could race
the submission thread and pick up the wrong fence when cloing.
v2: Use copy semantic for clone_syncobj_dma_fence() (Jason)
Do the cloning prior to adding the syncobj to anv_queue_submit so
that if the cloning fails don't have an invalid syncobj in
anv_queue_submit (Jason)

v4: Fix invalid argument order (Lionel)

In order to implement GL_PRIMITIVES_GENERATED, v3d allocates a small
resource and adds a command to the job to store the prim counts to it.
However it was only doing this when TF was enabled which meant that if
the query was used with a geometry shader but no TF then the query would
always be zero. This patch makes the driver keep track of how many
PRIMITIVES_GENERATED queries are in flight and then enable writing the
prim count if its more than zero.

this was a little spaghetti-ish: the module hash was sometimes being applied
during module update, sometimes in draw during program create, and then also
it was removed when a shader unbind would cause the program to no longer be reachable
now things are more consistent:
* keep removing module hash when program becomes unreachable
* only apply module hash in draw during updates there

When the client calls vkMapMemory(), we have to align the requested
offset down to the nearest page or else the map will fail. On platforms
where we have DRM_IOCTL_I915_GEM_MMAP_OFFSET, we always map the whole
buffer. In either case, the original map may start before the requested
offset and we need to take that into account when we clflush.
