git://anongit.freedesktop.org/git/drm-misc into drm-next First -misc pull for 4.11: - drm_mm rework + lots of selftests (Chris Wilson) - new connector_list locking+iterators - plenty of kerneldoc updates - format handling rework from Ville - atomic helper changes from Maarten for better plane corner-case handling in drivers, plus the i915 legacy cursor patch that needs this - bridge cleanup from Laurent - plus plenty of small stuff all over - also contains a merge of the 4.10 docs tree so that we could apply the dma-buf kerneldoc patches It's a lot more than usual, but due to the merge window blackout it also covers about 4 weeks, so all in line again on a per-week basis. The more annoying part with no pull request for 4 weeks is managing cross-tree work. The -intel pull request I'll follow up with does conflict quite a bit with -misc here. Longer-term (if drm-misc keeps growing) a drm-next-queued to accept pull request for the next merge window during this time might be useful. I'd also like to backmerge -rc2+this into drm-intel next week, we have quite a pile of patches waiting for the stuff in here. * tag 'drm-misc-next-2016-12-30' of git://anongit.freedesktop.org/git/drm-misc: (126 commits) drm: Add kerneldoc markup for new @scan parameters in drm_mm drm/mm: Document locking rules drm: Use drm_mm_insert_node_in_range_generic() for everyone drm: Apply range restriction after color adjustment when allocation drm: Wrap drm_mm_node.hole_follows drm: Apply tight eviction scanning to color_adjust drm: Simplify drm_mm scan-list manipulation drm: Optimise power-of-two alignments in drm_mm_scan_add_block() drm: Compute tight evictions for drm_mm_scan drm: Fix application of color vs range restriction when scanning drm_mm drm: Unconditionally do the range check in drm_mm_scan_add_block() drm: Rename prev_node to hole in drm_mm_scan_add_block() drm: Fix O= out-of-tree builds for selftests drm: Extract struct drm_mm_scan from struct drm_mm drm: Add asserts to catch overflow in drm_mm_init() and drm_mm_init_scan() drm: Simplify drm_mm_clean() drm: Detect overflow in drm_mm_reserve_node() drm: Fix kerneldoc for drm_mm_scan_remove_block() drm: Promote drm_mm alignment to u64 drm: kselftest for drm_mm and restricted color eviction ...
2016-12-18drm: bridge: Link encoder and bridge in core codeLaurent Pinchart2-8/+3
Instead of linking encoders and bridges in every driver (and getting it wrong half of the time, as many drivers forget to set the drm_bridge encoder pointer), do so in core code. The drm_bridge_attach() function needs the encoder and optional previous bridge to perform that task, update all the callers.

Replace uses of fb->bits_per_pixel with fb->format->cpp[0]*8. Less duplicated information is a good thing. Note that I didn't put parens around the cpp*8 in the below cocci script, on account of not wanting spurious parens all over the place. Instead I did the unsafe way, and tried to look over the entire diff to spot if any dangerous expressions were produced. I didn't see any. There are some cases where previously the code did X*bpp/8, so the division happened after the multiplication. Those are now just X*cpp so the division effectively happens before the multiplication, but that is perfectly fine since bpp is always a multiple of 8. @@ struct drm_framebuffer *FB; expression E; @@ drm_helper_mode_fill_fb_struct(...) { ... - FB->bits_per_pixel = E; ... } @@ struct drm_framebuffer *FB; expression E; @@ i9xx_get_initial_plane_config(...) { ... - FB->bits_per_pixel = E; ... } @@ struct drm_framebuffer *FB; expression E; @@ ironlake_get_initial_plane_config(...) { ... - FB->bits_per_pixel = E; ... } @@ struct drm_framebuffer *FB; expression E; @@ skylake_get_initial_plane_config(...) { ... - FB->bits_per_pixel = E; ... } @@ struct drm_framebuffer FB; expression E; @@ ( - E * FB.bits_per_pixel / 8 + E * FB.format->cpp[0] | - FB.bits_per_pixel / 8 + FB.format->cpp[0] | - E * FB.bits_per_pixel >> 3 + E * FB.format->cpp[0] | - FB.bits_per_pixel >> 3 + FB.format->cpp[0] | - (FB.bits_per_pixel + 7) / 8 + FB.format->cpp[0] | - FB.bits_per_pixel + FB.format->cpp[0] * 8 | - FB.format->cpp[0] * 8 != 8 + FB.format->cpp[0] != 1 ) @@ struct drm_framebuffer *FB; expression E; @@ ( - E * FB->bits_per_pixel / 8 + E * FB->format->cpp[0] | - FB->bits_per_pixel / 8 + FB->format->cpp[0] | - E * FB->bits_per_pixel >> 3 + E * FB->format->cpp[0] | - FB->bits_per_pixel >> 3 + FB->format->cpp[0] | - (FB->bits_per_pixel + 7) / 8 + FB->format->cpp[0] | - FB->bits_per_pixel + FB->format->cpp[0] * 8 | - FB->format->cpp[0] * 8 != 8 + FB->format->cpp[0] != 1 ) @@ struct drm_plane_state *state; expression E; @@ ( - E * state->fb->bits_per_pixel / 8 + E * state->fb->format->cpp[0] | - state->fb->bits_per_pixel / 8 + state->fb->format->cpp[0] | - E * state->fb->bits_per_pixel >> 3 + E * state->fb->format->cpp[0] | - state->fb->bits_per_pixel >> 3 + state->fb->format->cpp[0] | - (state->fb->bits_per_pixel + 7) / 8 + state->fb->format->cpp[0] | - state->fb->bits_per_pixel + state->fb->format->cpp[0] * 8 | - state->fb->format->cpp[0] * 8 != 8 + state->fb->format->cpp[0] != 1 ) @@ @@ - (8 * 8) + 8 * 8 @@ struct drm_framebuffer FB; @@ - (FB.format->cpp[0]) + FB.format->cpp[0] @@ struct drm_framebuffer *FB; @@ - (FB->format->cpp[0]) + FB->format->cpp[0] @@ @@ struct drm_framebuffer { ... - int bits_per_pixel; ... }; v2: Clean up the 'cpp*8 != 8' and '(8 * 8)' cases (Laurent) v3: Adjusted the semantic patch a bit and regenerated due to code changes Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> (v1) Link: http://patchwork.freedesktop.org/patch/msgid/1481751140-18352-1-git-send-email-ville.syrjala@linux.intel.com

2016-12-05drm/exynos: Use VIDEO_SAMSUNG_EXYNOS_GSC=n as GSC Kconfig dependencyJavier Martinez Canillas1-1/+1
Commit aeefb36832e5 ("drm/exynos: gsc: add device tree support and remove usage of static mappings") made the DRM_EXYNOS_GSC Kconfig symbol to only be selectable if the exynos-gsc V4L2 driver isn't enabled, since both use the same HW IP block. But added the dependency as depends on !VIDEO_SAMSUNG_EXYNOS_GSC which is not correct since Kconfig expressions are not boolean but tristate. So it will only evaluate to 'n' if VIDEO_SAMSUNG_EXYNOS_GSC=y but will evaluate to 'm' if VIDEO_SAMSUNG_EXYNOS_GSC=m. This means that both the V4L2 and DRM drivers can be enabled if the former is enabled as a module, which isn't what we want since otherwise 2 drivers could attempt to use the hardware at the same time.

2016-10-26drm: Don't force all planes to be added to the state due to zposVille Syrjälä3-1/+22
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.

drm_atomic_state has a complicated single owner model that tracks the single reference from allocation through to destruction on another thread - or perhaps on a local error path. We can simplify this tracking by using reference counting (at a cost of a few more atomics).

2016-10-01drm/exynos: g2d: use autosuspend mode for PM runtimeTobias Jakobi1-2/+7
The runqueue worker currently issues a get() when a new node is processed, and a put() once a node is completed. The corresponding suspend and resume calls currently only do clock gating, but with the upcoming introduction of IOMMU runpm also the corresponding IOMMU domain gets enabled (for get()) and disabled (for put()). This introduces performance regressions with we mitigate here. Switch PM runtime to autosuspend, such that clock gating and IOMMU control only happens when the engine is idle for a 'long' time.

2016-10-01drm/exynos: g2d: wait for engine to finishTobias Jakobi1-7/+77
While the engine works on a runqueue node it does memory access to the buffers associated with that node. Make sure that the engine is idle when g2d_close() and/or g2d_remove() are called, i.e. buffer associated with the process (for g2d_close()), or all buffers (for g2d_remove()) can be safely be unmapped. We have to take into account that the engine might be in an undefined state, i.e. it hangs and doesn't become idle. In this case, we issue a hardware reset to return the hardware and the driver context into a proper state.

This reverts commit b05984e21a7e000bf5074ace00d7a574944b2c16. The change, i.e. merging the sleep and runpm operations, produces a deadlock situation: (1) exynos_g2d_exec_ioctl() prepares a runqueue node and calls g2d_exec_runqueue() (2) g2d_exec_runqueue() calls g2d_dma_start() which gets runtime PM sync (3) runtime PM core calls g2d_runtime_resume() (4) g2d_runtime_resume() calls g2d_exec_runqueue(), which loops back to (2) Due to mutexes that are in place, a deadlock situation is created.

2016-10-01drm/exynos: fix pending update handlingAndrzej Hajda3-60/+2
Exynos DRM devices update their registers at vblank time. Exynos-DRM uses custom mechanism to wait for vblank. This mechanism is error prone - variables are not updated atomically. As a result in certain circumstances user space can try to free buffers which are still in use by hardware, in such cases IOMMU can throw OOPS. The patch instead of fixing the mechanism replaces it with drm core helper.
