This cap bit only affects DRI_PRIME setups. Since iris now uses the
blitter to perform dGPU -> iGPU copies asynchronously, it's better to
always use at least two backbuffers so the 3D engine can start rendering
the next frame during the copy.
See commit d17e752857 where this change
was made for radeonsi.

In a hybrid graphics setup, Mesa allocates two buffers for the window
surface. The first is what the discrete card renders to; it lives in
VRAM and is usually tiled and possibly compressed. The second is a
shadow copy that lives in system memory (readable by the integrated
card with the displays); it's usually linear and uncompressed.
Mesa's window system code schedules blits to update the shadow copy
when needed, typically at the end of a frame. These can be fairly
costly when running a full-screen application at high resolutions.
We'd like to use the blitter for these copies, as it lets us perform
the copy asynchronously, letting the 3D engine race ahead and start
rendering the next frame. If we used the 3D engine, the next frame
could not start rendering until the PRIME blit finishes, giving us
less time to draw the frame. Fortunately, Tigerlake introduced new
blitter commands which can operate at full memory bandwidth.
DRI PRIME blits happen via the Gallium blit() hook. We can detect that
case by looking for the PIPE_BIND_PRIME_BLIT_DST flag on the destination
resource. This patch detects that case and calls iris_copy_region() on
IRIS_BATCH_BLITTER to handle it. We know a priori that the blitter can
handle this operation (it's not a scaled blit, the formats match and
should not be 96bpp, there's no combined depth stencil, or other weird
edge cases). blorp_copy() will also assert that edge cases don't occur.
Together with the next patch, this improves performance on DG1 Hybrid
scenarios by about 5-6%.

Use drmSyncobjSignal to signal out_syncobjs when a GPU job submission
ends in the simulator. With this, we can enable multisync support in the
simulator and keep the multisync approach to process fence by submitting
a serialized no-op job that adds the fence to the array of out syncobjs,
i.e. syncobjs to be signaled in the kernel when a job completes (job
post deps).

Copying per compoents might flush NaN values, leading to changes in the

of the cases here we can do even better, and just copy the whole damn

Given that our fcsels are on float-bools, we can emit the LRP directly and
save the backend having to emit a SLT to turn the CMP src[0] into a bool.
This required passing a codegen flags struct for nir-to-tgsi. I think
this is a good way forward for it, as the alternative I think has mostly
been adding flags to nir_shader_compiler_options (since adding
PIPE_SHADER_CAPs is an unreasonable amount of pain).
