2016-12-15drm: Replace 'format->format' comparisons to just 'format' comparisonsVille Syrjälä
Rather than compare the format u32s of two format infos, we can direclty compare the format info pointers themselves. Noramlly all the ->format pointers all point to somwehere in the big array, so this is a valid way to test for equality. Also drivers may want to point ->format at a private format info struct instead (eg. for special compressed formats with extra planes), so just comparing the pixel format values wouldn't necessaritly even work. But comparing the pointers will also take care of that case. @@ struct drm_framebuffer *a; struct drm_framebuffer *b; @@ ( - a->format->format != b->format->format + a->format != b->format | - a->format->format == b->format->format + a->format == b->format ) @@ struct drm_plane_state *a; struct drm_plane_state *b; @@ ( - a->fb->format->format != b->fb->format->format + a->fb->format != b->fb->format | - a->fb->format->format == b->fb->format->format + a->fb->format == b->fb->format ) @@ struct drm_crtc *crtc; struct drm_framebuffer *x; @@ ( - crtc->primary->fb->format->format != x->format->format + crtc->primary->fb->format != x->format | - x->format->format != crtc->primary->fb->format->format + x->format != crtc->primary->fb->format ) @@ struct drm_mode_set *set; @@ - set->fb->format->format != set->crtc->primary->fb->format->format + set->fb->format != set->crtc->primary->fb->format Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Suggested-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1479498793-31021-35-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

2016-12-15drm: Nuke fb->bits_per_pixelVille Syrjälä
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

The kms state itself is already protected by the modeset locks acquired by the drm core. The only thing left is gem bo state, and since the cursor code expects small objects which are statically mapped at create time and then invariant over the lifetime of the gem bo there's nothing to protect. See armada_gem_dumb_create -> armada_gem_linear_back which assigns obj->addr which is the only thing used by the cursor code. Only tricky bit is to switch to the _unlocked unreference function.

2015-09-15drm/armada: move vbl code into armada_crtcRussell King
Our vblank event code belongs in armada_crtc.c rather than the core of the driver. Move it there. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2015-09-15drm/armada: remove non-component supportRussell King
Now that the transition of TDA998x to the component helpers is complete, remove the non-componentised support from the Armada DRM driver. All outputs are expected to use the component helpers from now on. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2015-07-15drm/armada: avoid saving the adjusted mode to crtc->modeRussell King
We're not supposed to store the adjusted mode into crtc->mode. We don't use it anyway, so we can safely remove this. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2014-12-10drm/armada: Remove dummy ->load_lut() implementationThierry Reding
The ->load_lut() callback is optional, therefore a dummy implementation is not needed. Cc: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2014-11-12Merge tag 'v3.18-rc4' into drm-nextDave Airlie
backmerge to get vmwgfx locking changes into next as the conflict with per-plane locking.
2014-11-05drm: Move drm_crtc_init from drm_crtc.h to drm_plane_helper.hDaniel Vetter
Just a bit of OCD cleanup on headers - this function isn't the core interface any more but just a helper for drivers who haven't yet transitioned to universal planes. Put the declaration at the right spot and sprinkle necessary #includes over all drivers. Maybe this helps to encourage driver maintainers to do the switch. v2: Fix #include ordering for tegra, reported by 0-day builder. v3: Include required headers, reported by Thierry.

2014-10-17drm/armada: convert to use vblank_on/off callsRussell King
A future commit changes the way various vblank calls behave, which causes drivers to break. Converting to use the drm_crtc_vblank_on/off calls avoids this breakage. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2014-10-17drm/armada: fix page_flip refcounting leakRussell King
A refcounting leak was found of the original frame buffer attached to the CRTC when using the page_flip ioctl, resulting in the frame buffer never being freed. This was not obvious initially, as if the page flip subsequently re-attaches the original frame buffer, the refcounts will be balanced. However, if the original frame buffer is freed, then it will be leaked. Fix this by ensuring that we take a reference on the incoming fb, but rely on the queued work to drop that ref count.

Pull DRM updates from Dave Airlie: "Like all good pull reqs this ends with a revert, so it must mean we tested it, [ Ed. That's _one_ way of looking at it ] This pull is missing nouveau, Ben has been stuck trying to track down a very longstanding bug that revealed itself due to some other changes. I've asked him to send you a direct pull request for nouveau once he cleans things up. I'm away until Monday so don't want to delay things, you can make a decision on that when he sends it, I have my phone so I can ack things just not really merge much. It has one trivial conflict with your tree in armada_drv.c, and also the pull request contains some component changes that are already in your tree, the base tree from Russell went via Greg's tree already, but some stuff still shows up in here that doesn't when I merge my tree into yours.

2014-07-11drm/armada: register crtc with portRussell King
Register the CRTC with the port node so that the DRM OF helpers can find the appropriate CRTC. This is important so that encoders can identify their corresponding possible CRTCs. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2014-07-03drm/armada: move variant initialisation to CRTC initRussell King
Move the variant initialisation entirely to the CRTC init function - the variant support is really about the CRTC properties than the whole system, and we want to treat each CRTC individually when we support DT. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2014-07-03drm/armada: use number of CRTCs registeredRussell King
Use the number of CRTCs registered to size the vblank arrays rather than our own count. Number CRTCs using this as well. This permits us to register CRTCs as components in the near future rather than as part of a single device. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
