Subject: [PATCH 0/4] share semaphore across process
Date: Thu, 18 Aug 2016 15:55:55 +0800 [thread overview]
Message-ID: <1471506959-905-1-git-send-email-David1.Zhou@amd.com> (raw)
after ctx id is valid in global side, we share semaphore across process based on BO sharing mechanism.
That means we map semaphore object to a bo, then sharing bo with other process, the other process can
get the semaphore object from the sharing bo.
Chunming Zhou (4):
amdgpu: use drm_amdgpu_fence instead of amdgpu_cs_fence in semaphore
structure
amdgpu: add export/import semaphore apis
amdgpu: add mutex for across process reason
tests/amdgpu: add semaphore across process test
amdgpu/amdgpu.h | 40 ++++++++++++++
amdgpu/amdgpu_cs.c | 113 ++++++++++++++++++++++++++++++++------
amdgpu/amdgpu_internal.h | 6 ++-
tests/amdgpu/basic_tests.c | 131 +++++++++++++++++++++++++++++++++++++++++++++
