2022-05-04drm/nouveau: remove trace_dma_fence_emitChristian König1-1/+0

2022-04-07dma-buf: specify usage while adding fences to dma_resv obj v7Christian König1-1/+3
Instead of distingting between shared and exclusive fences specify the fence usage while adding fences. Rework all drivers to use this interface instead and deprecate the old one. v2: some kerneldoc comments suggested by Daniel v3: fix a missing case in radeon v4: rebase on nouveau changes, fix lockdep and temporary disable warning v5: more documentation updates v6: separate internal dma_resv changes from this patch, avoids to disable warning temporary, rebase on upstream changes v7: fix missed case in lima driver, minimize changes to i915_gem_busy_ioctl Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20220407085946.744568-3-christian.koenig@amd.com
2022-04-07dma-buf: add enum dma_resv_usage v4Christian König1-3/+5
This change adds the dma_resv_usage enum and allows us to specify why a dma_resv object is queried for its containing fences. Additional to that a dma_resv_usage_rw() helper function is added to aid retrieving the fences for a read or write userspace submission. This is then deployed to the different query functions of the dma_resv object and all of their users. When the write paratermer was previously true we now use DMA_RESV_USAGE_WRITE and DMA_RESV_USAGE_READ otherwise. v2: add KERNEL/OTHER in separate patch v3: some kerneldoc suggestions by Daniel v4: some more kerneldoc suggestions by Daniel, fix missing cases lost in the rebase pointed out by Bas.

A variety of tweaks to the NVIF library interfaces, mostly ripping out things that turned out to be not so useful. - Removed refcounting from nvif_object, callers are expected to not be stupid instead. - nvif_client is directly reachable from anything derived from nvif_object, removing the need for heuristics to locate it - _new() versions of interfaces, that allocate memory for the object they construct, have been removed. The vast majority of callers used the embedded _init() interfaces. - No longer storing constructor arguments (and the data returned from nvkm) inside nvif_object, it's more or less unused and just wastes memory.

2014-08-10drm/nouveau: initial pass at moving to struct nvif_deviceBen Skeggs1-1/+1
This is an attempt at isolating some of the changes necessary to port to NVIF in a separate commit. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-08-10drm/nouveau/core: rework event interfaceBen Skeggs1-10/+16
This is a lot of prep-work for being able to send event notifications back to userspace. Events now contain data, rather than a "something just happened" signal. Handler data is now embedded into a containing structure, rather than being kmalloc()'d, and can optionally have the notify routine handled in a workqueue. Various races between suspend/unload with display HPD/DP IRQ handlers automagically solved as a result. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2013-12-18drm: Kill DRM_HZDaniel Vetter1-1/+1
We don't have any userspace interfaces that use HZ as a time unit, so having our own DRM define is useless. Remove this remnant from the shared drm core days. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Dave Airlie <airlied@redhat.com>

2013-11-08drm/nouveau/core: convert event handler apis to split create/enable semanticsBen Skeggs1-8/+11
This is a necessary step towards being able to work with the insane locking requirements of the DRM core's vblank routines, and a nice cleanup as a side-effect. This is similar in spirit to the interfaces that Peter Hurley arrived at with his nouveau_event rcu conversion series. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-11-08drm/nouveau/core: Add priv field for event handlersPeter Hurley1-13/+7
Provide private field for event handlers exclusive use. Convert nouveau_fence_wait_uevent() and nouveau_fence_wait_uevent_handler(); drop struct nouveau_fence_uevent. Signed-off-by: Peter Hurley <peter@hurleysoftware.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-07-10drm/nouveau: bump fence timeout to 15 secondsMaarten Lankhorst1-1/+1
calim didn't like 150 seconds timeout, so lower the timeout for him. 15 seconds should still be plenty. Signed-off-by: Maarten Lankhorst <maarten.lankhorst@canonical.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-07-01drm/nouveau: delay busy bo vma removal until fence signalsBen Skeggs1-5/+68
As opposed to an explicit wait. Allows userspace to not stall waiting on buffer deletion. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
