2018-12-05drm: Add helper iterator functions for plane fb_damage_clips blobDeepak Rawat
With fb_damage_clips blob property in drm_plane_state, this patch adds helper iterator to traverse the damage clips that lie inside plane src. Iterator will return full plane src as damage in case need full plane update or damage is not specified. v2: - Plane src clipping correction - Handle no plane update case in iter_next Signed-off-by: Deepak Rawat <drawat@vmware.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com>

2018-12-05drm: Add a new plane property to send damage during plane updateLukasz Spintzyk
FB_DAMAGE_CLIPS is an optional plane property to mark damaged regions on the plane in framebuffer coordinates of the framebuffer attached to the plane. The layout of blob data is simply an array of "struct drm_mode_rect". Unlike plane src coordinates, damage clips are not in 16.16 fixed point. As plane src in framebuffer cannot be negative so are damage clips. In damage clip, x1/y1 are inclusive and x2/y2 are exclusive. This patch also exports the kernel internal drm_rect to userspace as drm_mode_rect. This is because "struct drm_clip_rect" is not sufficient to represent damage for current plane size. Driver which are interested in enabling FB_DAMAGE_CLIPS property for a plane should enable this property using drm_plane_enable_damage_clips. v2: - Input validation on damage clips against framebuffer size. - Doc update, other minor changes.

2018-12-04drm/i915: Allocate a common scratch pageChris Wilson
Currently we allocate a scratch page for each engine, but since we only ever write into it for post-sync operations, it is not exposed to userspace nor do we care for coherency. As we then do not care about its contents, we can use one page for all, reducing our allocations and avoid complications by not assuming per-engine isolation. For later use, it simplifies engine initialisation (by removing the allocation that required struct_mutex!) and means that we can always rely on there being a scratch page. v2: Check that we allocated a large enough scratch for I830 w/a Fixes: 06e562e7f515 ("drm/i915/ringbuffer: Delay after EMIT_INVALIDATE for gen4/gen5") # v4.18.20 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=108850 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Reviewed-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181204141522.13640-1-chris@chris-wilson.co.uk Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: <stable@vger.kernel.org> # v4.18.20+

2018-12-04drm/i915: Introduce per-engine workaroundsTvrtko Ursulin
We stopped re-applying the GT workarounds after engine reset since commit 59b449d5c82a ("drm/i915: Split out functions for different kinds of workarounds"). Issue with this is that some of the GT workarounds live in the MMIO space which gets lost during engine resets. So far the registers in 0x2xxx and 0xbxxx address range have been identified to be affected. This losing of applied workarounds has obvious negative effects and can even lead to hard system hangs (see the linked Bugzilla). Rather than just restoring this re-application, because we have also observed that it is not safe to just re-write all GT workarounds after engine resets (GPU might be live and weird hardware states can happen), we introduce a new class of per-engine workarounds and move only the affected GT workarounds over. Using the framework introduced in the previous patch, we therefore after engine reset, re-apply only the workarounds living in the affected MMIO address ranges. v2: * Move Wa_1406609255:icl to engine workarounds as well. * Rename API. (Chris Wilson) * Drop redundant IS_KABYLAKE. (Chris Wilson) * Re-order engine wa/ init so latest platforms are first.

2018-12-04drm/i915: Record GT workarounds in a listTvrtko Ursulin
To enable later verification of GT workaround state at various stages of driver lifetime, we record the list of applicable ones per platforms to a list, from which they are also applied. The added data structure is a simple array of register, mask and value items, which is allocated on demand as workarounds are added to the list. This is a temporary implementation which later in the series gets fused with the existing per context workaround list handling. It is separated at this stage since the following patch fixes a bug which needs to be as easy to backport as possible. Also, since in the following patch we will be adding a new class of workarounds (per engine) which can be applied from interrupt context, we straight away make the provision for safe read-modify-write cycle. v2: * Change dev_priv to i915 along the init path. (Chris Wilson) * API rename. (Chris Wilson) v3: * Remove explicit list size tracking in favour of growing the allocation in power of two chunks.

2018-12-04drm/exynos/iommu: merge IOMMU and DMA codeAndrzej Hajda
As DMA code is the only user of IOMMU code both files can be merged. It allows to remove stub functions, after slight adjustment of exynos_drm_register_dma.

2018-12-04drm/exynos/iommu: integrate IOMMU/DMA internal APIAndrzej Hajda
Exynos DRM drivers should work with and without IOMMU. Providing common API generic to both scenarios should make code cleaner and allow further code improvements. The patch removes including of exynos_drm_iommu.h as the file contains mostly IOMMU specific stuff, instead it exposes exynos_drm_*_dma functions and puts them into exynos_drm_dma.c.

2018-12-03drm/v3d: Add more tracepoints for V3D GPU rendering.Eric Anholt
The core scheduler tells us when the job is pushed to the scheduler's queue, and I had the job_run functions saying when they actually queue the job to the hardware. By adding tracepoints for the very top of the ioctls and the IRQs signaling job completion, "perf record -a -e v3d:.\* -e gpu_scheduler:.\* <job>; perf script" gets you a pretty decent timeline.
