Change return value to int to propagate errors from gamma_set, and remove start parameter. Updates always use the full size, and some drivers even ignore the start parameter altogether. This is needed for atomic drivers, where an atomic commit can fail with -EINTR or -ENOMEM and should be restarted. This is already and issue for drm_atomic_helper_legacy_set_gamma, which this patch fixes up. Changes since v1: - Fix compiler warning.

Just fallout from switching from asciidoc to sphinx/rst. v2: Found more. Also s/\//#/ in the vgpu ascii-art - sphinx treats those as comments and switch to variable-width, which wreaks the layout. v3: Undo some of the hacks, rebasing onto latest version of Jani's series fixed it. Acked-by:

Currently the plane's index is determined by walking the list of all planes in the mode and finding the position of that plane in the list. A linear walk, especially a linear walk within a linear walk as frequently conceived by i915.ko [O(N^2)] quickly comes to dominate profiles. The plane's index is constant for as long as no earlier planes are removed from the list. For all drivers, planes are static, determined at boot and then untouched until shutdown. In fact, there is no locking provided to allow for dynamic removal of planes/encoders/crtcs. v2: Convert drm_crtc_index() and drm_encoder_index() as well. v3: Stop adjusting the indices upon removal; consider the list construct-only.

Now a drm_pending_event can either send a real drm_event or signal a fence, or both. It allow us to signal via fences when the buffer is displayed on the screen. Which in turn means that the previous buffer is not in use anymore and can be freed or sent back to another driver for processing. v2: Comments from Daniel Vetter - call fence_signal in drm_send_event_locked() - remove unneeded !e->event check v3: Remove drm_pending_event->destroy to fix a leak when e->file_priv is not set.

It's silly to have 2 mallocs when we could tie these two together. Also, Gustavo adds another one in his per-crtc out-fence patches. And I want to add more stuff here for nonblocking commit helpers. In the future we can use this to store a pointer to the preceeding state, making an atomic update entirely free-standing. This will be needed to be able to queue them up with a depth > 1.

It's kinda pointless to have 2 separate mallocs for these. And when we add more per-plane state in the future it's even more pointless. Right now there's no such thing planned, but both Gustavo's per-crtc fence patches, and some nonblocking commit helpers I'm playing around with will add more per-crtc stuff. It makes sense to also consolidate planes, just for consistency. In the future we can use this to store a pointer to the preceeding state, making an atomic update entirely free-standing.

... and use it in msm&vc4. Again just want to encapsulate drm_atomic_state internals a bit. The const threading is a bit awkward in vc4 since C sucks, but I still think it's worth to enforce this. Eventually I want to make all the obj->state pointers const too, but that's a lot more work ... v2: Provide safe macro to wrap up the unsafe helper better, suggested by Maarten. v3: Fixup subject (Maarten) and spelling fixes (Eric Engestrom).

Mostly this is unexpected indents. But really it's just a demonstration for my patch, all these issues have been found&fixed using the correct source file and line number support I just added. All line numbers have been perfectly accurate. One issue looked a bit fishy in intel_lrc.c, where I don't quite grok what sphinx is unhappy about. But since that file looks like it has never seen a proper kernel-doc parser I figured better to fix in a separate path. v2: Use fancy new &drm_device->struct_mutex linking (Jani).

This avois leaking drm_atomic_state internals into the helpers. The only place where this still happens after this patch is drm_atomic_helper_swap_state(). It's unavoidable there, and maybe a good indicator we should actually move that function into drm_atomic.c. Signed-off-by:

The intention of using video=<connector>:<mode> is primarily to select the user's preferred resolution at startup. Currently we always create a new mode irrespective of whether the monitor has a native mode at the desired resolution. This has the issue that we may then select the fake mode rather the native mode during fb_helper->inital_config() and so if the fake mode is invalid we then end up with a loss of signal. Oops. This invalid fake mode would also be exported to userspace, who potentially may make the same mistake. To avoid this issue, we filter out the added command line mode if we detect the desired resolution (and clock if specified) amongst the probed modes. This fixes the immediate problem of adding a duplicate mode, but perhaps more generically we should avoid adding a GTF mode if the monitor has an EDID that is not GTF-compatible, or similarly for CVT.

struct fence_array inherits from struct fence and carries a collection of fences that needs to be waited together. It is useful to translate a sync_file to a fence to remove the complexity of dealing with sync_files on DRM drivers. So even if there are many fences in the sync_file that needs to waited for a commit to happen, they all get added to the fence_collection and passed for DRM use as a standard struct fence. That means that no changes needed to any driver besides supporting fences. To avoid fence_array's fence allocates a new timeline if needed (when combining fences from different timelines). v2: Comments by Daniel Vetter: - merge fence_collection_init() and fence_collection_add() - only add callbacks at ->enable_signalling() - remove fence_collection_put() - check for type on to_fence_collection() - adjust fence_is_later() and fence_later() to WARN_ON() if they are used with collection fences. v3: - Initialize fence_cb.node at fence init. Comments by Chris Wilson: - return "unbound" on fence_collection_get_timeline_name() - don't stop adding callbacks if one fails - remove redundant !! on fence_collection_enable_signaling() - remove redundant () on fence_collection_signaled - use fence_default_wait() instead v4 (chk): Rework, simplification and cleanup: - Drop FENCE_NO_CONTEXT handling, always allocate a context. - Rename to fence_array. - Return fixed driver name. - Register only one callback at a time. - Document that create function takes ownership of array. v5 (chk): More work and fixes: - Avoid deadlocks by adding all callbacks at once again. - Stop trying to remove the callbacks. - Provide context and sequence number for the array fence. v6 (chk): Fixes found during testing - Fix stupid typo in _enable_signaling().

Fence contexts are created on the fly (for example) by the GPU scheduler used in the amdgpu driver as a result of an userspace request. Because of this userspace could in theory force a wrap around of the 32bit context number if it doesn't behave well. Avoid this by increasing the context number to 64bits. This way even when userspace manages to allocate a billion contexts per second it takes more than 500 years for the context number to wrap around. v2: fix printf formats as well. Signed-off-by:
