2016-11-28drm: Fix conflicting macro parameter in drm_mm_for_each_node_in_range()Chris Wilson
start is being used as both a macro parameter and as a member of struct drm_mm_node (node->start). This causes a conflict as cpp then tries to replace node->start with the passed in string for "start". Work just fine so long as you also happened to using local variables called start!

2016-11-22drm/atomic: Unconfuse the old_state mess in commmit_tailDaniel Vetter
I totally butcherd the job on typing the kernel-doc for these, and no one realized. Noticed by Russell. Maarten has a more complete approach to this confusion, by making it more explicit what the new/old state is, instead of this magic switching behaviour. v2: - Liviu pointed out that wait_for_fences is even more magic. Leave that as @state, and document @pre_swap better. - While at it, patch in header for the reference section. - Fix spelling issues Russell noticed. v3: Fix up the @pre_swap note (Liviu): Also s/synchronous/blocking/, since async flip is something else than non-blocking.

2016-11-17drm: Nuke modifier[1-3]Ville Syrjälä
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: Kristian Høgsberg <hoegsberg@gmail.com> Acked-by: Ben Widawsky <ben@bwidawsk.net> Acked-by: Daniel Stone <daniels@collabora.com> Acked-by: Rob Clark <robdclark@gmail.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1479295996-26246-1-git-send-email-ville.syrjala@linux.intel.com
2016-11-16drm/fence: add out-fences supportGustavo Padovan
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. Comment by Daniel Vetter: - Add clean up code for out_fences v3: Comments by Daniel Vetter: - create DRM_MODE_ATOMIC_EVENT_MASK - userspace should fill out_fences_ptr with the crtc_ids for which it wants fences back. v4: Create OUT_FENCE_PTR properties and remove old approach. v5: Comments by Brian Starkey: - Remove extra fence_get() in atomic_ioctl() - Check ret before iterating on the crtc_state - check ret before fd_install - set fence_state to NULL at the beginning - check fence_state->out_fence_ptr before put_user() - change order of fput() and put_unused_fd() on failure - Add access_ok() check to the out_fence_ptr received - Rebase after fence -> dma_fence rename - Store out_fence_ptr in the drm_atomic_state - Split crtc_setup_out_fence() - return -1 as out_fence with TEST_ONLY flag v6: Comments by Daniel Vetter - Add prepare/unprepare_crtc_signaling() - move struct drm_out_fence_state to drm_atomic.c - mark get_crtc_fence() as static Comments by Brian Starkey - proper set fence_ptr fence_state array - isolate fence_idx increment - improve error handling v7: Comments by Daniel Vetter - remove prefix from internal functions - make out_fence_ptr an s64 pointer - degrade DRM_INFO to DRM_DEBUG_ATOMIC when put_user fail - fix doc issues - filter out OUT_FENCE_PTR == NULL and do not fail in this case - add complete_crtc_signalling() - krealloc fence_state on demand Comment by Brian Starkey - remove unused crtc_state arg from get_out_fence() v8: Comment by Brian Starkey - cancel events before check for !fence_state - convert a few lefovers u64 types for out_fence_ptr - fix memleak by assign fence_state earlier after realloc - proper accout num_fences in case of error v9: Comment by Brian Starkey - memset last position of fence_state after krealloc Comments by Sean Paul - pass install_fds in complete_crtc_signaling() instead of ret - put_user(-1, fence_ptr) when decoding props v10: Comment by Brian Starkey - remove unneeded num_fences increment on error path - kfree fence_state after installing fences fd v11: rebase against latest drm-misc v12: rebase again against latest drm-misc Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Reviewed-by: Brian Starkey <brian.starkey@arm.com> (v10) Reviewed-by: Sean Paul <seanpaul@chromium.org> Tested-by: Robert Foss <robert.foss@collabora.com> (v10) [danvet: Appease checkpatch.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1479301221-13056-1-git-send-email-gustavo@padovan.org

2016-11-16drm/fence: add in-fences supportGustavo Padovan
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: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Reviewed-by: Brian Starkey <brian.starkey@arm.com> Reviewed-by: Sean Paul <seanpaul@chromium.org> Tested-by: Robert Foss <robert.foss@collabora.com> [danvet: Rebase onto extracted drm_mode_config.[hc].] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

The function's behaviour was changed in 90844f00049e, without changing its signature, causing people to keep using it the old way without realising they were now leaking memory. Rob Clark also noticed it was also allocating GFP_KERNEL memory in atomic contexts, breaking them. Instead of having to allocate GFP_ATOMIC memory and fixing the callers to make them cleanup the memory afterwards, let's change the function's signature by having the caller take care of the memory and passing it to the function. The new parameter is a single-field struct in order to enforce the size of its buffer and help callers to correctly manage their memory.

2016-11-08drm: Track drm_mm allocators and show leaks on shutdownChris Wilson
We can use the kernel's stack tracer and depot to record the allocation site of every drm_mm user.

2016-10-26drm: Don't force all planes to be added to the state due to zposVille Syrjälä
We don't want all planes to be added to the state whenever a plane with fixed zpos gets enabled/disabled. This is true especially for eg. cursor planes on i915, as we want cursor updates to go through w/o throttling. Same holds for drivers that don't support zpos at all (i915 actually falls into this category right now since we've not yet added zpos support). Allow drivers more freedom by letting them deal with zpos themselves instead of doing it in drm_atomic_helper_check_planes() unconditionally. Let's just inline the required calls into all the driver that currently depend on this. v2: Inline the stuff into the drivers instead of adding another helper, document things better (Daniel) Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Marek Szyprowski <m.szyprowski@samsung.com> Cc: Benjamin Gaignard <benjamin.gaignard@linaro.org> Cc: Vincent Abriou <vincent.abriou@st.com> Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Cc: Inki Dae <inki.dae@samsung.com> Cc: Joonyoung Shim <jy0922.shim@samsung.com> Cc: Seung-Woo Kim <sw0312.kim@samsung.com> Cc: Kyungmin Park <kyungmin.park@samsung.com> Cc: Lyude <cpaul@redhat.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: stable@vger.kernel.org Fixes: 44d1240d006c ("drm: add generic zpos property") Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Sean Paul <seanpaul@chromium.org> Acked-by: Benjamin Gaignard <benjamin.gaignard@linaro.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1476111056-12734-1-git-send-email-ville.syrjala@linux.intel.com

2016-10-25dma-buf: Rename struct fence to dma_fenceChris Wilson
I plan to usurp the short name of struct fence for a core kernel struct, and so I need to rename the specialised fence/timeline for DMA operations to make room. A consensus was reached in https://lists.freedesktop.org/archives/dri-devel/2016-July/113083.html that making clear this fence applies to DMA operations was a good thing. Since then the patch has grown a bit as usage increases, so hopefully it remains a good thing!
