The Broadwell GT3 machine has two independent BSD rings that can be used to process the video commands. New execution flags are added to export the two rings to userspace so that userspace can specify the bsd ring. The LOCAL_ flags could be removed when this patch is merged into libdrm and i-g-t depends on that new libdrm. http://lists.freedesktop.org/archives/intel-gfx/2014-December/056569.html Zhipeng Gong (3): i-g-t: check whether kernel has dual bsd ring tests/gem_exec_params: check the invalid flags for dual bsd ring test/gem_dummy_reloc_loop: add tests for dual bsd ring lib/ioctl_wrappers.c | 16 ++++++++++++++++ lib/ioctl_wrappers.h | 1 + tests/gem_dummy_reloc_loop.c | 18 ++++++++++++++++++ tests/gem_exec_params.c | 41 +++++++++++++++++++++++++++++++++++++++++ 4 files changed, 76 insertions(+) -- 1.8.3.1 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
