lima: actually wait for bo in lima_bo_wait

PIPE_TIMEOUT_INFINITE is unsigned and gets assigned to signed fields
where it ends up as -1. When this reaches the kernel as a timeout it
gets translated as no timeout, which cause the waiting functions to
return immediately and not actually wait for a completion.

etnaviv: Fix double-free in etna_bo_cache_free()

The following situation can happen in a multithreaded OpenGL application.
A BO is submitted from etna_cmd_stream #1 with flags set for read.
A BO is submitted from etna_cmd_stream #2 with flags set for write.
This triggers a flush on stream #1 and clears the BO's current_stream
pointer. If at this point, stream #2 attempts to queue BO again, which
does happen, the BO will be added to the submit list twice. The Linux
kernel driver correctly detects this and warns about it with "BO at
index %u already on submit list" kernel message.

However, when cleaning the BO cache in etna_bo_cache_free(), the BO
which was submitted twice will also be free()d twice, this triggering
a glibc double free detector.

The fix is easy, even if the BO does not have current_stream set,
iterate over current streams' list of BOs before adding the BO to it
and verify that the BO is not yet there.

5 years agopanfrost: Implement transform feedback
Alyssa Rosenzweig [Fri, 9 Aug 2019 19:32:49 +0000 (12:32 -0700)]
panfrost: Implement transform feedback

Midgard has no hardware support for transform feedback, so we simulate
it in software. Lucky us.

What Midgard does do is write out vertex shader outputs to main memory
unconditonally. Fragment shaders read varyings back from main memory;
there's no on-chip storage for varyings. Whether this was a reasonable
design is a question I will not be engaging in this commit message.

What that does mean is that, in some sense, Midgard *always* does
transform feedback uncondtionally, and there's no way to turn off
transform feedback. Normally, we would allocate some scratch memory
every frame to store the varyings in an arbitrary format (interleaved
for simplicity), and then feed that scratch to the fragment shader and
discard when the rendering completes.

The only difference now is that sometimes, for some buffers, we use a BO
provided to us by Gallium and a format provided by Gallium, instead of
allocating the memory and choosing the format ourselves. This has some
limitations -- in particular, it only works at vec4 granularity, so a
corresponding GLSL linkage patch is needed to correctly implement
transform feedback for non-vec4 types. Nevertheless, given the hardware
already works in this admittedly-bizarre fashion, transform feedback is
"free". Or, at least, it's no more expensive than any other rendering.

Specifically not implemented is dynamically-sized transform feedback
(i.e. with geometry/tesselation shaders).

Spoiler alert: Midgard has no support for geometry *or* tessellation
shaders, despite advertising support. They get compiled to *massive*
compute shaders. How's that for checkbox compliance?
