This backend interacts with the new DRM driver for Midgard GPUs which is
currently in development.
When using this backend, Panfrost has roughly on-par functionality as
when using the non-DRM driver from Arm.
Alyssa Rosenzweig: To do so, we implement additional routines for
runtime GPU version detection and fencing. We cleanup some duplicate
code interfering with the new driver. We fix a long-standing memory leak
which is aggravated on the new driver. Finally, we implement BO
import/export in a way compatible with the new driver. These changes are
squashed to preserve bisectability given the hard-to-track ABI shifts in
the nondrm module

Non-zero offset wasn't working, which breaks a bunch of
dEQP-GLES31.functional.texture.border_clamp.formats.* when doing sharded
deqp runs (because order of tests changes, resulting in different
texture state bound.. deqp doesn't really clean up it's gl state between
tests very well)
Previously, if additional textures were bound, due to using too small of
a bcolor_entry size, the last 32bytes of the bcolor_entry would be
overwritten.

Most hw on the native platform advertise these
caps this way.
D3DCAPS_READ_SCANLINE: We don't really have hardware
support for that, but many games don't even check the
flag, and expect GetRasterStatus to work, which is
why we emulated it with a timer (like wine). So we
may as well advertise the cap.

With createImage(), the caller was expected to set a SHARED flag if they
needed the ability to get a GEM handle. DRI3, wayland, and gbm all set
it, EGL_MESA_drm_image passes it through, and surfaceless doesn't need it
because there's no way to request a handle.
With the new createImageWithModifiers() DRI method to replace it, the
expectation is that you'll always be able to share the buffer, so the flag
is unnecessary in its arguments. However, we do need to tell gallium
about this expectation.
Without this, kmscube's modifiers path using
gbm_bo_create_with_modifiers(&modifier, 1) instead of
gbm_bo_create(SCANOUT | SHARED) will call the driver's resource_create()
function wtih PIPE_BIND_SHARED unset, so the driver (particularly
renderonly drivers) may allocate in such a way that it can't return an
answer from gbm_bo_get_handle(). I used to have a hack in v3d using
count==1 && modifier==LINEAR to indicate that you wanted SHARED anyway,
but that was dropped recently.

I'll want to use this for transfer maps, which already do their own
flushing. This lets us avoid a double flush, and also gives us more
control over the batch which is selected.
We were using batch->contains_draw as a proxy for "are we even using
this engine?" That isn't quite right, because it only counts regular
draws. BLORP operations may have also rendered to a resource, which
needs to trigger flushing. To check for this, we also see if the
render and sometimes depth caches are non-empty.
We can also drop the "but there might already be stale data in the
cache even if we haven't emitted any commands yet" concern in the
comments. The kernel flushes caches between batches.
This may not be great but it's at least better than what was there.
By mistake, this was previously set for all shaders.
It is a vertex shader property so only makes sense to
set it for vertex shaders.

We need a version of fd6_tex_swiz() that just returns the composed
swizzle without building part of the TEX_CONST_0 state. So just
refactor the existing function to build more of the TEX_CONST_0 state,
and leave fd6_tex_swiz() simply composing swizzles.
The small IBO state change (to use LINEAR for smaller sizes/levels) is
to match the state in fd6_tex_const_0(). It seems like maybe tiled
actually works at the smaller sizes but not if minification is in play,
so best just to make images match what we do for textures.

For texturing, we map alpha formats to the corresponding red format,
as many alpha formats are outright missing, and red is more efficient
when sampling anyway.
When rendering to A8_UNORM, we use that format directly, so the image
gets the shader output's .a/.w channel, rather than the .r/.x channel.
All other A* formats are non-renderable, so we can't do much and just
mark them as unsupported for rendering. Fortunately, GL only requires
rendering to A8_UNORM, so that works out.
According to Andre Heider and Timur Kristóf, this fixes font rendering
in Witcher 1 (via nine). Andre also reported that it fixes Unigine
Heaven (presumably via nine).
v2: Use the same swizzle for both sampler views and "render targets".
BLORP expects the read swizzle, and will take the inverse when
setting up the destination swizzle (and actually applying it in
the shaders). We ignore the format swizzle when setting up normal
rendering SURFACE_STATEs, which is necessary because it would be
an illegal shader channel select combination. Thanks to Jason
Ekstrand for pointing out that BLORP took an inverse swizzle.

Gallium might call us multiple times to bind subsets of the samplers,
at which point we'd recreate the table a bunch of times. It doesn't
really buy us anything to do it here - even if we defer to draw time,
the dirty tracking ensures we'll only do it on the first draw after a
bind_sampler_states() call.
We now use the number of samplers specified by the shader instead of
the binding count. If this number changes, we flag sampler state as
dirty so we re-upload a table with the right number of entries.
This also fixes a bug where ice->state.need_border_colors was never
unset, so once something needed border colors, the pool would always
be pinned in all future batches.
v2: Explicitly flag sampler states as dirty, rather than assuming that
bind_sampler_states() will be called if the program texture count
changes. While this may be true for st/mesa, it isn't the case for
Gallium HUD.
