40777984 - drm/vgem: Attach sw fences to exported vGEM dma-buf (ioctl)

Fri, 15 Jul 2016 08:31:11 +0000

drm/vgem: Attach sw fences to exported vGEM dma-buf (ioctl)vGEM buffers are useful for passing data between software clients andhardware renders. By allowing the user to create and attach fences tothe exported vGEM buffers (on the dma-buf), the user can implement adeferred renderer and queue hardware operations like flipping and thensignal the buffer readiness (i.e. this allows the user to scheduleoperations out-of-order, but have them complete in-order).This also makes it much easier to write tightly controlled testcases fordma-buf fencing and signaling between hardware drivers.v2: Don't pretend the fences exist in an ordered timeline, but allocatea separate fence-context for each fence so that the fences areunordered.v3: Make the debug output more interesting, and show the signaled status.v4: Automatically signal the fence to prevent userspace fromindefinitely hanging drivers.Testcase: igt/vgem_basic/dmabuf-fenceTestcase: igt/vgem_slow/nohangSigned-off-by: Chris Wilson Cc: Sean Paul Cc: Zach Reizner Cc: Gustavo Padovan Cc: Daniel Vetter Acked-by: Zach Reizner Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/1468571471-12610-1-git-send-email-chris@chris-wilson.co.uk List of files: /linux-6.15/drivers/gpu/drm/vgem/Makefile

990ed272 - drm/vgem: drop DRIVER_PRIME (v2)

Thu, 21 May 2015 15:58:30 +0000

drm/vgem: drop DRIVER_PRIME (v2)For actual sharing of buffers with other drivers (ie. actual hardware)we'll need to pimp things out a bit better to deal w/ caching, multiplememory domains, etc. See thread: http://lists.freedesktop.org/archives/dri-devel/2015-May/083160.htmlBut for the llvmpipe use-case this isn't a problem. Nor do we reallyneed prime/dri3 (dri2 is sufficient). So until the other issues aresorted lets remove DRIVER_PRIME.v2: also drop the dead code[airlied: Okay I'm convinced this API could have a lot of use cases that are really really bad, yes the upload use case is valid however that isn't the only use case enabled, and if we allow all the other use cases, people will start to (ab)use them, and then they'll be ABI and my life will get worse, so disable PRIME for now]Acked-by: Thomas Hellstrom Acked-by: Daniel Vetter Signed-off-by: Rob Clark Signed-off-by: Dave Airlie List of files: /linux-6.15/drivers/gpu/drm/vgem/Makefile

502e95c6 - drm/vgem: implement virtual GEM

Thu, 05 Mar 2015 00:33:41 +0000

drm/vgem: implement virtual GEMThis patch implements the virtual GEM driver with PRIME sharing whichallows vgem to import a gem object from other drivers for the purposeof mmap-ing them to userspace. The mmap is done using the mmapoperation exported by other drivers.v2: remove platform_device and do not attach to dma bufsv3: use drm helpers for get/put pagesv4: correct dumb create pitchReviewed-by: Rob Clark (v3)Reviewed-by: Stéphane Marchesin (v3)Signed-off-by: Adam Jackson Signed-off-by: Ben Widawsky Signed-off-by: Zach Reizner Signed-off-by: Dave Airlie List of files: /linux-6.15/drivers/gpu/drm/vgem/Makefile
