According to mali_kbase, all Bifrost and Valhall GPUs are affected by
issue TSIX_2033. This hardware bug breaks the INTERSECT frame shader
mode when forcing clean_tile_writes. What does that mean?
The hardware considers a tile "clean" if it has been cleared but not
drawn to. Setting clean_tile_write forces the hardware to write back
such "clean" tiles to main memory.
Bifrost hardware supports frame shaders, which insert a rectangle into
every tile according to a configured rule. Frame shaders are used in
Panfrost to implement tile reloads (i.e. LOAD_OP_LOAD). Two modes are
relevant to the current discussion: ALWAYS, which always inserts a frame
shader, and INTERSECT, which tries to only insert where there is
geometry. Normally, we use INTERSECT for tile reloads as it is more
efficient than ALWAYS-- it allows us to skip reloads of tiles that are
discarded and never written back to memory.
From a software perspective, Panfrost's current logic is correct: if we
clear, we set clean_tile_writes, else we use an INTERSECT frame shader.
There is no software interaction between the two.
Unfortunately, there is a hardware interaction. The hardware forces
clean_tile_writes in certain circumstances when AFBC is used.
Ordinarily, this is a hardware implementation detail and invisible to
software. Unfortunately, this implicit clean tile write is enough to
trigger the hardware bug when using INTERSECT. As such, we need to
detect this case and use ALWAYS instead of INTERSECT for correct
results.

The gl_FragColor lowering in the fragment shader depends on the number
of render targets, which can change every set_framebuffer_state.
set_framebuffer_state thus needs to force a rebind of the fragment
shader.

This uses the new property for AFBC we've added. The AFBC quirk is
applied only to v4, and we only set dev->has_afbc on v5+ so this is not
a regression. It now respects the hardware-specific AFBC disable.

u_format defines depth formats as having depth in .x, mesa/st samples for
depth or stencil in .x (not making use of any other channels).
util_make_fs_blit_zs() looks for depth or stencil in .x. The MSAA path
was the exception looking for it in .z or .y, which was causing drivers to
need to splat their values out to the other channels. This should be
better on hardware that can emit shorter messages for sampling just the
first channels.

If the application first uses nontrivial divisors, the driver emits
the vertex shader VA to the upload BO rather than directly via the
user SGPRs locations. But, if the vertex input dynamic state changes,
the driver might select a different VS prolog that no longer needs
nontrivial divisors.
In this case, the driver needs to re-emit the prolog inputs because
otherwise the VS prolog will jump to the PC that is emitted via the
user SGPR locations, and the previous one was somewhere in the
upload BO...
This fixes a GPU hang with Bioshock and Zink.
