2016-12-18drm: Don't include <drm/drm_encoder.h> in <drm/drm_crtc.h>Laurent Pinchart1-0/+1
<drm/drm_crtc.h> used to define most of the in-kernel KMS API. It has now been split into separate files for each object type, but still includes most other KMS headers to avoid breaking driver compilation. As a step towards fixing that problem, remove the inclusion of <drm/drm_encoder.h> from <drm/drm_crtc.h> and include it instead where appropriate. Also remove the forward declarations of the drm_encoder and drm_encoder_helper_funcs structures from <drm/drm_crtc.h> as they're not needed in the header. <drm/drm_encoder.h> now has to include <drm/drm_mode.h> and contain a forward declaration of struct drm_encoder in order to allow including it as the first header in a compilation unit.

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

2016-08-12drm/fb-helper: Add a dummy remove_conflicting_framebuffersDaniel Vetter2-2/+2
Lots of drivers don't properly compile without this when CONFIG_FB=n. It's kinda a hack, but since CONFIG_FB doesn't stub any fucntions when it's disabled I think it makes sense to add it to drm_fb_helper.h. Long term we probably need to rethink all the logic to unload firmware framebuffer drivers, at least if we want to be able to move away from CONFIG_FB and fbcon. v2: Unfortunately just stubbing out remove_conflicting_framebuffers in drm_fb_helper.h upset gcc about static vs. non-static declarations, so a new wrapper it needs to be.

2015-09-24drm/mgag200: Fix driver_load error handlingArchit Taneja1-16/+20
mgag200_driver_load's error path just calls the drm driver's driver_unload op. It isn't safe to call this because it doesn't handle things well if driver_load fails somewhere mid way. Replace the call to mgag200_driver_unload with a more finegrained error handling path.
