Use dev_printk() when possible. This makes messages more consistent with other device-related messages and, in some cases, adds useful information. This changes messages like this: vgaarb: failed to allocate pci device vgaarb: setting as boot device: PCI:0000:01:00.0 vgaarb: device added: PCI:0000:01:00.0,decodes=io+mem,owns=io+mem,locks=none vgaarb: bridge control possible 0000:01:00.0 to this: pci 0000:01:00.0: vgaarb: failed to allocate VGA arbiter data pci 0000:01:00.0: vgaarb: setting as boot VGA device pci 0000:01:00.0: vgaarb: VGA device added: decodes=io+mem,owns=io+mem,locks=none pci 0000:01:00.0: vgaarb: bridge control possible No functional change intended.

It has been suggested that having per-plane modifiers is making life more difficult for userspace, so let's just retire modifier[1-3] and use modifier[0] to apply to the entire framebuffer. Obviosuly this means that if individual planes need different tiling layouts and whatnot we will need a new modifier for each combination of planes with different tiling layouts. For a bit of extra backwards compatilbilty the kernel will allow non-zero modifier[1+] but it require that they will match modifier[0]. This in case there's existing userspace out there that sets modifier[1+] to something non-zero with planar formats. Mostly a cocci job, with a bit of manual stuff mixed in. @@ struct drm_framebuffer *fb; expression E; @@ - fb->modifier[E] + fb->modifier @@ struct drm_framebuffer fb; expression E; @@ - fb.modifier[E] + fb.modifier Cc: Kristian Høgsberg <hoegsberg@gmail.com> Cc: Ben Widawsky <benjamin.widawsky@intel.com> Cc: Rob Clark <robdclark@gmail.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Tomeu Vizoso <tomeu@tomeuvizoso.net> Cc: dczaplejewicz@collabora.co.uk Suggested-by:

Looking at the ioctl permission checks I noticed that it's impossible to import gem buffers into a control nodes, and fd2handle/handle2fd also don't work, so no joy with dma-bufs. The only way to do anything with a control node is by drawing stuff into a dumb buffer and displaying that. I suspect control nodes are an entirely unused thing, and a cursory check shows that there does not seem to be any callers of drmOpenControl nor of the other drmOpen functions using DRM_MODE_CONTROL. Since I don't like dead uabi, let's remove it. But since this would be a really big change I think it's better to start out small by simply not registering anything. We can garbage-collect the dead code later on, once we're sure it's really not used anywhere. Acked-by:

FS threading brings performance improvements of 0-20% in glmark2. The validation code checks for thread switch signals and ensures that the registers of the other thread are not touched, and that our clamps are not live across thread switches. It also checks that the threading and branching instructions do not interfere. (Original patch by Jonas, changes by anholt for style cleanup, removing validation the kernel doesn't need to do, and adding the flag for userspace). v2: Minor style fixes from checkpatch.

Support DRM out-fences by creating a sync_file with a fence for each CRTC that sets the OUT_FENCE_PTR property. We use the out_fence pointer received in the OUT_FENCE_PTR prop to send the sync_file fd back to userspace. The sync_file and fd are allocated/created before commit, but the fd_install operation only happens after we know that commit succeed. v2: Comment by Rob Clark: - Squash commit that adds DRM_MODE_ATOMIC_OUT_FENCE flag here.

Create one timeline context for each CRTC to be able to handle out-fences and signal them.

There is now a new property called IN_FENCE_FD attached to every plane state that receives sync_file fds from userspace via the atomic commit IOCTL. The fd is then translated to a fence (that may be a fence_array subclass or just a normal fence) and then used by DRM to fence_wait() for all fences in the sync_file to signal. So it only commits when all framebuffers are ready to scanout. v2: Comments by Daniel Vetter: - remove set state->fence = NULL in destroy phase - accept fence -1 as valid and just return 0 - do not call fence_get() - sync_file_fences_get() already calls it - fence_put() if state->fence is already set, in case userspace set the property more than once. v3: WARN_ON if fence is set but state has no FB v4: Comment from Maarten Lankhorst - allow set fence with no related fb v5: rename FENCE_FD to IN_FENCE_FD v6: Comments by Daniel Vetter: - rename plane_state->in_fence back to "fence" - re-introduce WARN_ON if fence set but no fb - rebase after fence -> dma_fence rename v7: Comments by Brian Starkey - set state->fence to NULL when duplicating the state - fail if IN_FENCE_FD was already set v8: rebase against latest drm-misc Signed-off-by:Brian Starkey <brian.starkey@arm.com> Reviewed-by:

Reference from drm_dp_aux description (about transfer): Upon success, the implementation should return the number of payload bytes that were transferred, or a negative error-code on failure. Helpers propagate errors from the .transfer() function, with the exception of the -EBUSY error, which causes a transaction to be retried. On a short, helpers will return -EPROTO to make it simpler to check for failure. The analogix_dp_transfer will return num_transferred, but if there is none byte been transferred, the return value will be 0, which means success, we should return error-code if transfer none byte. for (retry = 0; retry < 32; retry++) { err = aux->transfer(aux, &msg); if (err < 0) { if (err == -EBUSY) continue; goto unlock; } } Cc: zain wang <wzz@rock-chips.com> Reviewed-by:Jianqun Xu <jay.xu@rock-chips.com> Signed-off-by:

This reverts commit 6dffd431. Adding new mode flags willy nilly breaks existing userspace. We need to coordinate this better, potentially with a new client cap that only exposes the aspect ratio flags when userspace is prepared for them (similar to what we do with stereo 3D modes). This also broke things so that we would always send out VIC==0 in the AVI infoframe unless the user specified an aspect ratio via the mode flags. And the automagic RGB full vs. limited range handling was similartly broken as the user mode would never match any CEA mode.
