[igt-dev] [PATCH i-g-t v2 0/3] Add GEM_MMAP_OFFSET support in IGT.

[igt-dev] [PATCH i-g-t v2 0/3] Add GEM_MMAP_OFFSET support in IGT.

[Zbigniew Kempczyński]

Enable GEM_MMAP_OFFSET uAPI.

Series comes from split 'LMEM enabling in IGT'.
Mmap_offset will land before memory region so add support for it.

v2: Change WC -> WB according to review

[igt-dev] [PATCH i-g-t v2 3/3] tests/i915/gem_mmap_offset: Add new API test for gem_mmap_offset

[Zbigniew Kempczyński]

From: Lukasz Kalamarz <lukasz.kalamarz@intel.com>

Few simple tests which tries to create / mmap buffer objects
using GEM_MMAP_OFFSET uAPI.

v2: change from WC -> WB (according to Chris review comment)

Hmm, was about to say missed one...

But you have a coherency check here, when all I was expecting was
...

... this mmap exists after gem_close().

I'd strongly advocate making these two independent tests. As the
mmap-vs-gem_close deserves more thorough probing as it is a source of
kernel use-after-frees (see gem_mmap_gtt::test_close_race) And
flink_race etc. But before we get into the prolonged races a simple
mmap-exists-after-close is a good basic test.
