Hi Maarten Will this stop the stuttering I've been seeing with DRI3 and PRIME? Or will other patches / plumbing be required Cheers Mike <div class="gmail_quote">On 9 Jul 2014 13:29, "Maarten Lankhorst" <<a href="mailto:maarten.lankhorst@canonical.com">maarten.lankhorst@canonical.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> This series applies on top of the driver-core-next branch of git://<a href="http://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git" target="_blank">git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git</a> Before converting ttm to the new fence interface I had to fix some drivers to require a reservation before poking with fence_obj. After flipping the switch RCU becomes available instead, and the extra reservations can be dropped again. :-) I've done at least basic testing on all the drivers I've converted at some point, but more testing is definitely welcomed! --- Maarten Lankhorst (17): drm/ttm: add interruptible parameter to ttm_eu_reserve_buffers drm/ttm: kill off some members to ttm_validate_buffer drm/nouveau: add reservation to nouveau_gem_ioctl_cpu_prep drm/nouveau: require reservations for nouveau_fence_sync and nouveau_bo_fence drm/ttm: call ttm_bo_wait while inside a reservation drm/ttm: kill fence_lock drm/nouveau: rework to new fence interface drm/radeon: add timeout argument to radeon_fence_wait_seq drm/radeon: use common fence implementation for fences drm/qxl: rework to new fence interface drm/vmwgfx: get rid of different types of fence_flags entirely drm/vmwgfx: rework to new fence interface drm/ttm: flip the switch, and convert to dma_fence drm/nouveau: use rcu in nouveau_gem_ioctl_cpu_prep drm/radeon: use rcu waits in some ioctls drm/vmwgfx: use rcu in vmw_user_dmabuf_synccpu_grab drm/ttm: use rcu in core ttm drivers/gpu/drm/nouveau/core/core/event.c | 4 drivers/gpu/drm/nouveau/nouveau_bo.c | 59 +--- drivers/gpu/drm/nouveau/nouveau_display.c | 25 +- drivers/gpu/drm/nouveau/nouveau_fence.c | 431 +++++++++++++++++++---------- drivers/gpu/drm/nouveau/nouveau_fence.h | 22 + drivers/gpu/drm/nouveau/nouveau_gem.c | 55 +--- drivers/gpu/drm/nouveau/nv04_fence.c | 4 drivers/gpu/drm/nouveau/nv10_fence.c | 4 drivers/gpu/drm/nouveau/nv17_fence.c | 2 drivers/gpu/drm/nouveau/nv50_fence.c | 2 drivers/gpu/drm/nouveau/nv84_fence.c | 11 - drivers/gpu/drm/qxl/Makefile | 2 drivers/gpu/drm/qxl/qxl_cmd.c | 7 drivers/gpu/drm/qxl/qxl_debugfs.c | 16 + drivers/gpu/drm/qxl/qxl_drv.h | 20 - drivers/gpu/drm/qxl/qxl_fence.c | 91 ------ drivers/gpu/drm/qxl/qxl_kms.c | 1 drivers/gpu/drm/qxl/qxl_object.c | 2 drivers/gpu/drm/qxl/qxl_object.h | 6 drivers/gpu/drm/qxl/qxl_release.c | 172 ++++++++++-- drivers/gpu/drm/qxl/qxl_ttm.c | 93 ------ drivers/gpu/drm/radeon/radeon.h | 15 - drivers/gpu/drm/radeon/radeon_cs.c | 10 + drivers/gpu/drm/radeon/radeon_device.c | 60 ++++ drivers/gpu/drm/radeon/radeon_display.c | 21 + drivers/gpu/drm/radeon/radeon_fence.c | 283 +++++++++++++++---- drivers/gpu/drm/radeon/radeon_gem.c | 19 + drivers/gpu/drm/radeon/radeon_object.c | 8 - drivers/gpu/drm/radeon/radeon_ttm.c | 34 -- drivers/gpu/drm/radeon/radeon_uvd.c | 10 - drivers/gpu/drm/radeon/radeon_vm.c | 16 + drivers/gpu/drm/ttm/ttm_bo.c | 187 ++++++------- drivers/gpu/drm/ttm/ttm_bo_util.c | 28 -- drivers/gpu/drm/ttm/ttm_bo_vm.c | 3 drivers/gpu/drm/ttm/ttm_execbuf_util.c | 146 +++------- drivers/gpu/drm/vmwgfx/vmwgfx_buffer.c | 47 --- drivers/gpu/drm/vmwgfx/vmwgfx_drv.h | 1 drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c | 24 -- drivers/gpu/drm/vmwgfx/vmwgfx_fence.c | 329 ++++++++++++---------- drivers/gpu/drm/vmwgfx/vmwgfx_fence.h | 35 +- drivers/gpu/drm/vmwgfx/vmwgfx_resource.c | 43 +-- include/drm/ttm/ttm_bo_api.h | 7 include/drm/ttm/ttm_bo_driver.h | 29 -- include/drm/ttm/ttm_execbuf_util.h | 22 + 44 files changed, 1256 insertions(+), 1150 deletions(-) delete mode 100644 drivers/gpu/drm/qxl/qxl_fence.c -- Signature _______________________________________________ dri-devel mailing list <a href="mailto:dri-devel@lists.freedesktop.org">dri-devel@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/dri-devel" target="_blank">http://lists.freedesktop.org/mailman/listinfo/dri-devel</a> </blockquote></div>
