2018-03-01lib: Provide an accelerated routine for readback from WCChris Wilson
Reading from WC is awfully slow as each access is uncached and so performed synchronously, stalling for the memory load. x86 did introduce some new instructions in SSE 4.1 to provide a small internal buffer to accelerate reading back a cacheline at a time from uncached memory, for this purpose. v2: Don't be lazy and handle misalignment. v3: Switch out of sse41 before emitting the generic memcpy routine v4: Replace opencoded memcpy_from_wc v5: Always flush the internal buffer before use (Eric) v6: Assume bulk moves, so check for dst alignment. v7: Use _mm_fence for _buitlin_ia32_mfence for consistency, remove superfluous defines (Ville) Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Eric Anholt <eric@anholt.net> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com>
2017-10-09igt/gem_fence_thrash: Use streaming reads for verifyChris Wilson
At the moment, the verify tests use an extremely brutal write-read of every dword, degrading performance to UC. If we break those up into cachelines, we can do a wcb write/read at a time instead, roughly 8x faster. We lose the accuracy of the forced wcb flushes around every dword, but we are retaining the overall behaviour of checking reads following writes instead. To compensate, we do check that a single dword write/read before using wcb aligned accesses.

2017-09-08build: Nuke #ifdef HAVE_CONFIG_H cargo-cultDaniel Vetter
We have it. Daniel Stone said the #ifdef HAVE_CONFIG_H comes from the X11 transition to the modular build, where in the imake -> modular build transition config.h wasn't universally available. Now we just make this a requirement (so yeah Android better generate one too). v2: Improve commit message a bit.

2015-10-12Replace __gem_mmap__{cpu,gtt,wc}() + igt_assert() with gem_mmap__{cpu,gtt,wc}()Ville Syrjälä
gem_mmap__{cpu,gtt,wc}() already has the assert built in, so replace __gem_mmap__{cpu,gtt,wc}() + igt_assert() with it.

2015-10-09Make gem_mmap__{cpu,gtt,wc}() assert on failureVille Syrjälä
Rename the current gem_mmap__{cpu,gtt,wc}() functions into __gem_mmap__{cpu,gtt,wc}(), and add back wrappers with the original name that assert that the pointer is valid. Most callers will expect a valid pointer and shouldn't have to bother with failures. To avoid changing anything (yet), sed 's/gem_mmap__/__gem_mmap__/g' over the entire codebase.

2015-06-23igt/gem_fence_thrash: Reduce memory usageDerek Morton
On android platforms with 1Gb RAM gem_fence_thrash was failing with an out of memory error. This patch causes gem_close() to be called when a handle is no longer required rather than relying on the cleanup when the fd is closed. This greatly improves the memory footprint of the test allowing it to run on 1Mb systems. Also fixed a leak of the 'threads' variable. v2: Simplified as per Chris Wilson's suggestion.

2014-03-22tests|lib: remove assert.h includesDaniel Vetter
Only the igt core and non-test tools should have asserts to catch internal errors, tests and helper libraries should all user igt_asert instead. Fix things up where assert instead of igt_assert was used. One tiny step towards header sanity. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2013-11-01lib: add igt_main macroDaniel Vetter
In the past new testcases with subtest often forgot to add the call to igt_exit at the end of their main() function. That is now caught with a bit more obnoxious asserts, but it's still a nuissance. This little igt_main macro takes care of that (and also of calling the subtest machinery initialization code correctly). If no one objects I'll roll this out for all the simple cases (i.e. those tests that don't have additional argv parsing on top of the subtest machinery). v2: Roll it out across the board.

With this at least the y-tiled test reliably fails on my machines, but x-tiled still passes on some. More ideas to tune this highly welcome. v2: Fill cpu caches with data for each newly allocated bo. This seems to do the trick on my snb here _really_ reliably. So apparently the backsnoop for llc gtt writes is the crucial ingredient here to make the test fail.

Despite the name implying it's a standard part of the POSIX threads API, pthread_yield is actually non-standard and less portable than sched_yield.

2009-09-01Add gem_fence_thrash testChris Wilson
This is a test case that overcommits fence registers between threads, which are copying from one fenced bo to another. In earlier versions of the driver this would cause excessive spinning as the first inactive (i.e. not in use by the GPU) would be used to service the next page. After all the fence registers had been allocated, in effect only the very first fence would then be used for all subsequent faults.
