This is useful for BO leak debugging.

We didn't need any of it except for the list header, and qir.h pulls in
nir.h, which is not really interesting to winsys.
|

list.h is a nicer and more familiar set of list functions/macros.

NIR brings us better optimization than I would have bothered to write
within the driver, developers sharing future optimization work, and the
ability to share device-specific lowering code that we and other
GLES2-level drivers need.
total uniforms in shared programs: 13421 -> 13422 (0.01%)
uniforms in affected programs: 62 -> 63 (1.61%)
total instructions in shared programs: 39961 -> 39707 (-0.64%)
instructions in affected programs: 15494 -> 15240 (-1.64%)
v2: Add missing imov support, and assert that there are no dest saturates.
v3: Rebase on the target-specific algebraic series.
v4: Rebase on gallium-includes-from-NIR changes in mater.
v5: Rebase on variables being in lists instead of hash tables.
v6: Squash in intermediate changes that used the NIR-to-TGSI pass (which
I'm not committing)

Since our kernel BOs require CMA allocation, and the use of them requires
new mmaps, it's pretty expensive and we should avoid it if possible.
Copying my original design for Intel, make a userspace cache that reuses
BOs that haven't been shared to other processes but frees BOs that have
sat in the cache for over a second.
Improves glxgears framerate on RPi by around 30%.

This is nice when you're tracking down which command list is hanging the
GPU.

Our submits now return immediately and you have to manually wait for
things to complete if you want to (like a normal driver).

It was useful on i965, but it's even more useful for debugging tiled
renderers.

This still treats everything as RGBA8888 for the most part, same as
before. This is a prerequisite for handling other texture formats, since
only RGBA8888 has a raster-layout mode.

Fixes swapped colors on the copypix demo and some piglit tests like
pbo-teximage-tiling .

It's 2048x2048 that's the max, not 1024x1024.

This ensures that when I'm using the simulator, I get a closer match to
what behavior on real hardware will be. It lets me rapidly iterate on the
kernel validation code (which otherwise has a several-minute turnaround
time), and helps catch buffer overflow bugs in the userspace driver
faster.

v2: Fix an accidental deletion of some characters from the copyright
message (caught by Ilia Mirkin)

This mostly just takes every draw call and turns it into a sequence of
commands that clear the FBO and draw a single shaded triangle to it,
regardless of the actual input vertices or shaders. I copied the initial
driver skeleton mostly from freedreno, and I've preserved Rob Clark's
copyright for those. I also based my initial hardcoded shaders and
command lists on Scott Mansell (phire)'s "hackdriver" project, though the
bit patterns of the shaders emitted end up being different.
v2: Rebase on gallium megadrivers changes.
v3: Rebase on PIPE_SHADER_CAP_MAX_CONSTS change.
v4: Rely on simpenrose actually being installed when building for
simulation.
v5: Add more header duplicate-include guards.
v6: Apply Emil's review (protection against vc4 sim and ilo at the same
time, and dropping the dricommon drm bits) and fix a copyright header
(thanks, Roland)
