5 years agointel/vec4: Try to emit a VF source in try_immediate_source

intel/vec4: Try to emit a VF source in try_immediate_source

This commit is also a pre-requisite for the next commit.

No shader-db changes on any Gen8+ platform as these platforms do not use
the vec4 backend.

v2: Massive rebase on eeebeb211f1 ("intel/vec4: Try emitting non-scalar
immediates").  This change is a lot less helpful since that commit
landed (previously helped 1934 shaders on HSW) because, apparently, a
lot of the cases helped by that commit were things like vector loads of
{ 1.0, 1.0, 1.0 } that were also helped by this commit.

intel/fs: Add support for SLM fence in Gen11

Gen11 SLM is not on L3 anymore, so now the hardware has two separate
fences.  Add a way to control which fence types to use.

At this time, we don't have enough information in NIR to control the
visibility of the memory being fenced, so for now be conservative and
assume that fences will need a stall.  With more information later
we'll be able to reduce those.

features in one. And since OpenGL cares more about single features, it'd

As it turns, this is now relatively simple. We only really care about
three features using this cap, and those already got their own caps. So
we can remove it, and make sure all current drivers just give the same
response to all of them.

The only place we *really* care about SM3 is in nine, and there we can
instead just re-construct the information based on the finer-grained
caps. This avoids DX9 semantics from needlessly leaking into all of the

5 years agopanfrost: Update supported formats

panfrost: Update supported formats

Much of the format selection code was inherited from softpipe (!) of all
places, and a lot of it is accordingly cruft. Later if-elses were added
in random places to workaround missing formats at various points in
history. Clean up some of this.

Theoretically, any format we can texture from we can also render to. In
practice, there are a few corner cases that we need to disable
explicitly.

For one, we do have to restrict SCANOUT formats to workaround
buggy apps (in particular, dEQP which with --deqp-surface-type=window
under Weston will end up with RGB10_A2 and complain about low alpha
precision). Just be clearer about how/why.

Also, RGB5_A1 support is still broken; let's not worry about that quite
yet.
