7 years agoi965: Enable regular fast-clears (CCS_D) on gen9+
Jason Ekstrand [Thu, 22 Jun 2017 04:35:07 +0000 (21:35 -0700)]
i965: Enable regular fast-clears (CCS_D) on gen9+

The set of formats which supports CCS_E is actually fairly small on
gen9.  However, everything that supports fast-clears on gen8 also
supports fast-clears on gen9+.  The one very annoying exception is
that blending is broken for non-0/1 clear colors with sRGB formats.
In order to solve that problem, we do a resolve to get rid of the
clear color.  Another option would be to just not fast-clear with
non-0/1 clear colors however non-0/1 + blending + sRGB is uncommon
enough that this shouldn't be a significant performance problem.

This appears to help gl_manhattan31_off by about 2%.

intel/isl: Tighten up restrictions for CCS on gen7

It may technically be possible to enable some sort of fast-clear support
for at least the base slice of a 2D array texture on gen7.  However,
it's not documented to work, we've never tried to do it in GL, and we
have no idea what the hardware does if you turn on CCS_D with arrayed
rendering.  Let's just play it safe and disallow it for now.  If someone
really cares that much about gen7 performance, they can come along and
try to get it working later.

i965: Drop non-LLC lunacy in the program cache code.

The non-LLC story was a horror show.  We uploaded data via pwrite
(drm_intel_bo_subdata), which would stall if the cache BO was in
use (being read) by the GPU.  Obviously, we wanted to avoid that.
So, we tried to detect whether the buffer was busy, and if so, we'd
allocate a new BO, map the old one read-only (hopefully not stalling),
copy all shaders compiled since the dawn of time to the new buffer,
upload our new one, toss the old BO, and let the state upload code
know that our program cache BO changed.  This was a lot of extra data
copying, and flagging BRW_NEW_PROGRAM_CACHE would also cause a new
STATE_BASE_ADDRESS to be emitted, stalling the entire pipeline.

Not only that, but our rudimentary busy tracking consistented of a flag
set at execbuf time, and not cleared until we threw out the program
cache BO.  So, the first shader upload after any drawing would hit this
"abandon the cache and start over" copying path.

This is largely unnecessary - it's just ancient and crufty code.  We can
use the same persistent mapping paths on all platforms.  On non-ancient
kernels, this will use a write combining map, which should be reasonably
fast.

One aspect that is worse: we do occasionally grow the program cache BO,
and copy the old contents to the newer BO.  This will suffer from UC
readback performance now.  To mitigate this, we use the MOVNTDQA based
streaming memcpy on platforms with SSE 4.1 (all Gen7+ atoms).  Gen4-5
are unfortunately going to be penalized.

v2: Add MOVNTDQA path, rebase on other map flag changes.
v3: Drop cache->bo_used_by_gpu too (caught by Chris Wilson).

Kenneth Graunke [Mon, 17 Jul 2017 19:46:58 +0000 (12:46 -0700)]
i965/bufmgr: Explicitly wait instead of using I915_GEM_SET_DOMAIN.

With the advent of asynchronous maps, domain tracking doesn't make a
whole lot of sense.  Buffers can be in use on both the CPU and GPU at
the same time.  In order to avoid blocking, we stopped using set_domain
for asynchronous mappings, which means that the kernel's tracking has
lies.  We can't properly track it in userspace either, as the kernel
can change domains on us spontaneously (for example, when un-swapping).

According to Chris Wilson, I915_GEM_SET_DOMAIN does the following:

1. pins the backing storage (acquiring pages outside of the
   struct_mutex)

2. waits either for read/write access, including inter-device waits

3. updates the domain, clflushing as required

4. marks the object as used (for swapping)

5. turns off FBC/PSR/fancy scanout caching

Item (1) is not terribly important.  Most BOs are recycled via the
BO cache, so they already have pages.  Regardless, we fixed this
via an initial set_domain in the previous patch.

We implement item (2) with I915_GEM_WAIT.  This has one downside:
we'll stall unnecessarily if we do a read-only mapping of a buffer
that the GPU is reading.  I believe this is pretty uncommon.  We
may want to extend the wait ioctl at some point.

Mesa already does item (3) itself.  For cache-coherent buffers (most on
LLC systems), we don't need to do any clflushing - the CPU and GPU views
are coherent.  For non-coherent buffers (most on non-LLC systems), we
currently only use the CPU for read-only maps, and we explicitly clflush
when necessary.

We don't care about item (4)...swapping has already killed performance.
Plus, with async maps, the kernel's domain tracking is already bogus,
so it can't do this accurately regardless.

Item (5) should be okay because we avoid cached maps of scanout buffers.
