2017-01-19drm/i915: Track pinned vma in intel_plane_stateChris Wilson1-4/+4
With atomic plane states we are able to track an allocation right from preparation, during use and through to the final free after being swapped out for a new plane. We can couple the VMA we pin for the framebuffer (and its rotation) to this lifetime and avoid all the clumsy lookups in between. v2: Remove residual vma on plane cleanup (Chris) v3: Add a description for the vma destruction in intel_plane_destroy_state (Maarten) References: https://bugs.freedesktop.org/show_bug.cgi?id=98829 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170116152131.18089-1-chris@chris-wilson.co.uk Acked-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>

As I told people in [1] we really should not be confusing enum plane as a per-pipe plane identifier. Looks like that happened nonetheless, so let's fix it up by splitting the two into two enums. We'll also want something we just directly pass to various register offset macros and whatnot on SKL+. So let's make this new thing work for that. Currently we pass intel_plane->plane for the "sprites" and just a hardcoded zero for the "primary" planes. We want to get rid of that hardocoding so that we can share the same code for all planes (apart from the legacy cursor of course).

2016-11-17drm: Nuke modifier[1-3]Ville Syrjälä1-7/+7
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

Due to the plane->index not getting readjusted in drm_plane_cleanup(), we can't continue initialization of some plane/crtc init fails. Well, we sort of could I suppose if we left all initialized planes on the list, but that would expose those planes to userspace as well. But for crtcs the situation is even worse since we assume that pipe==crtc index occasionally, so we can't really deal with a partially initialize set of crtcs.

Now that we've make skl_wm_levels make a little more sense, we can remove all of the redundant wm information. Up until now we'd been storing two copies of all of the skl watermarks: one being the skl_pipe_wm structs, the other being the global wm struct in drm_i915_private containing the raw register values. This is confusing and problematic, since it means we're prone to accidentally letting the two copies go out of sync.

2016-09-07drm/i915/skl: Don't try to update plane watermarks if they haven't changedLyude1-2/+7
i915 sometimes needs to disable planes in the middle of an atomic commit, and then reenable them later in the same commit. Because of this, we can't make the assumption that the state of the plane actually changed. Since the state of the plane hasn't actually changed, neither have it's watermarks. And if the watermarks hasn't changed then we haven't populated skl_results with anything, which means we'll end up zeroing out a plane's watermarks in the middle of the atomic commit without restoring them later. Simple reproduction recipe: - Get a SKL laptop, launch any kind of X session - Get two extra monitors - Keep hotplugging both displays (so that the display configuration jumps from 1 active pipe to 3 active pipes and back) - Eventually underrun Changes since v1: - Fix incorrect use of "it's" Changes since v2: - Add reproduction recipe Signed-off-by: Lyude <cpaul@redhat.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Fixes: 62e0fb880123 ("drm/i915/skl: Update plane watermarks atomically during plane updates") Signed-off-by: Lyude <cpaul@redhat.com> Testcase: kms_plane Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1472488288-27280-1-git-send-email-cpaul@redhat.com Cc: drm-intel-fixes@lists.freedesktop.org
2016-08-23drm/i915/skl: Update plane watermarks atomically during plane updatesLyude1-0/+9
Thanks to Ville for suggesting this as a potential solution to pipe underruns on Skylake. On Skylake all of the registers for configuring planes, including the registers for configuring their watermarks, are double buffered. New values written to them won't take effect until said registers are "armed", which is done by writing to the PLANE_SURF (or in the case of cursor planes, the CURBASE register) register. With this in mind, up until now we've been updating watermarks on skl like this: non-modeset { - calculate (during atomic check phase) - finish_atomic_commit: - intel_pre_plane_update: - intel_update_watermarks() - {vblank happens; new watermarks + old plane values => underrun } - drm_atomic_helper_commit_planes_on_crtc: - start vblank evasion - write new plane registers - end vblank evasion } or modeset { - calculate (during atomic check phase) - finish_atomic_commit: - crtc_enable: - intel_update_watermarks() - {vblank happens; new watermarks + old plane values => underrun } - drm_atomic_helper_commit_planes_on_crtc: - start vblank evasion - write new plane registers - end vblank evasion } Now we update watermarks atomically like this: non-modeset { - calculate (during atomic check phase) - finish_atomic_commit: - intel_pre_plane_update: - intel_update_watermarks() (wm values aren't written yet) - drm_atomic_helper_commit_planes_on_crtc: - start vblank evasion - write new plane registers - write new wm values - end vblank evasion } modeset { - calculate (during atomic check phase) - finish_atomic_commit: - crtc_enable: - intel_update_watermarks() (actual wm values aren't written yet) - drm_atomic_helper_commit_planes_on_crtc: - start vblank evasion - write new plane registers - write new wm values - end vblank evasion } So this patch moves all of the watermark writes into the right place; inside of the vblank evasion where we update all of the registers for each plane. While this patch doesn't fix everything, it does allow us to update the watermark values in the way the hardware expects us to. Changes since original patch series: - Remove mutex_lock/mutex_unlock since they don't do anything and we're not touching global state - Move skl_write_cursor_wm/skl_write_plane_wm functions into intel_pm.c, make externally visible - Add skl_write_plane_wm calls to skl_update_plane - Fix conditional for for loop in skl_write_plane_wm (level < max_level should be level <= max_level) - Make diagram in commit more accurate to what's actually happening - Add Fixes: Changes since v1: - Use IS_GEN9() instead of IS_SKYLAKE() since these fixes apply to more then just Skylake - Update description to make it clear this patch doesn't fix everything - Check if pipes were actually changed before writing watermarks Changes since v2: - Write PIPE_WM_LINETIME during vblank evasion Changes since v3: - Rebase against new SAGV patch changes Changes since v4: - Add a parameter to choose what skl_wm_values struct to use when writing new plane watermarks Changes since v5: - Remove cursor ddb entry write in skl_write_cursor_wm(), defer until patch 6 - Write WM_LINETIME in intel_begin_crtc_commit() Changes since v6: - Remove redundant dirty_pipes check in skl_write_plane_wm (we check this in all places where we call this function, and it was supposed to have been removed earlier anyway) - In i9xx_update_cursor(), use dev_priv->info.gen >= 9 instead of IS_GEN9(dev_priv).

2016-08-11drm/i915: Compute display surface offset in the plane check hook for SKL+Ville Syrjälä1-23/+10
SKL has nasty limitations with the display surface offsets: * source x offset + width must be less than the stride for X tiled surfaces or the display engine falls over * the surface offset requires lots of alignment (256K or 1M) These facts mean that we can't just pick any suitably aligned tile boundary as the offset and expect the resulting x offset to be useable. The solution is to start with the closest boundary as before, but then keep searching backwards until we find one that works, or don't. This means we must be prepared to fail, hence the whole surface offset calculation needs to be moved to the .check_plane() hook from the .update_plane() hook. While at it we can check that the source width/height don't exceed maximum plane size limits. We'll store the results of the computation in the plane state to make it easy for the .update_plane() hook to do its thing. v2: Replace for+break loop with while loop Rebase due to drm_plane_state src/dst rects Rebase due to plane_check_state() Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Sivakumar Thulasimani <sivakumar.thulasimani@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1470821001-25272-11-git-send-email-ville.syrjala@linux.intel.com

2016-08-11drm/i915: Don't pass pitch to intel_compute_page_offset()Ville Syrjälä1-15/+11
intel_compute_page_offset() can dig up the correct pitch from the fb itself, no need for the caller to pass it in. A bit of extra care is needed for the lower level _intel_compute_page_offset() since that one gets called before the rotated pitch under intel_fb is populated. Note that we don't actually call it with anything but DRM_ROTATE_0 there so we wouldn't actually look up the rotated pitch there, but still, leave the pitch as something the caller has to pass to _intel_compute_page_offset() as an indicator that something is a bit special.

2016-08-11drm/i915: Rewrite fb rotation GTT handlingVille Syrjälä1-47/+50
Redo the fb rotation handling in order to: - eliminate the NV12 special casing - handle fb->offsets[] properly - make the rotation handling easier for the plane code To achieve these goals we reduce intel_rotation_info to only contain (for each plane) the rotated view width,height,stride in tile units, and the page offset into the object where the plane starts. Each plane is handled exactly the same way, no special casing for NV12 or other formats. We then store the computed rotation_info under intel_framebuffer so that we don't have to recompute it again. To handle fb->offsets[] we treat them as a linear offsets and convert them to x/y offsets from the start of the relevant GTT mapping (either normal or rotated). We store the x/y offsets under intel_framebuffer, and for some extra convenience we also store the rotated pitch (ie. tile aligned plane height). So for each plane we have the normal x/y offsets, rotated x/y offsets, and the rotated pitch. The normal pitch is available already in fb->pitches[]. While we're gathering up all that extra information, we can also easily compute the storage requirements for the framebuffer, so that we can check that the object is big enough to hold it. When it comes time to deal with the plane source coordinates, we first rotate the clipped src coordinates to match the relevant GTT view orientation, then add to them the fb x/y offsets. Next we compute the aligned surface page offset, and as a result we're left with some residual x/y offsets. Finally, if required by the hardware, we convert the remaining x/y offsets into a linear offset. For gen2/3 we simply skip computing the final page offset, and just convert the src+fb x/y offsets directly into a linear offset since that's what the hardware wants. After this all platforms, incluing SKL+, compute these things in exactly the same way (excluding alignemnt differences). v2: Use BIT(DRM_ROTATE_270) instead of ROTATE_270 when rotating plane src coordinates Drop some spurious changes that got left behind during development v3: Split out more changes to prep patches (Daniel) s/intel_fb->plane[].foo.bar/intel_fb->foo[].bar/ for brevity Rename intel_surf_gtt_offset to intel_fb_gtt_offset Kill the pointless 'plane' parameter from intel_fb_gtt_offset() v4: Fix alignment vs. alignment-1 when calling _intel_compute_tile_offset() from intel_fill_fb_info() Pass the pitch in tiles in stad of pixels to intel_adjust_tile_offset() from intel_fill_fb_info() Pass the full width/height of the rotated area to drm_rect_rotate() for clarity Use u32 for more offsets v5: Preserve the upper_32_bits()/lower_32_bits() handling for the fb ggtt offset (Sivakumar) v6: Rebase due to drm_plane_state src/dst rects Cc: Sivakumar Thulasimani <sivakumar.thulasimani@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Sivakumar Thulasimani <sivakumar.thulasimani@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1470821001-25272-2-git-send-email-ville.syrjala@linux.intel.com Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch>
