2021-03-31drm/displayid: add new displayid section/block iteratorsJani Nikula
Iterating DisplayID blocks across sections (in EDID extensions) is unnecessarily complicated for the caller. Implement DisplayID iterators to go through all blocks in all sections. Usage example: const struct displayid_block *block; struct displayid_iter iter; displayid_iter_edid_begin(edid, &iter); displayid_iter_for_each(block, &iter) { /* operate on block */ } displayid_iter_end(&iter); When DisplayID is stored in EDID extensions, the DisplayID sections map to extensions as described in VESA DisplayID v1.3 Appendix B: DisplayID as an EDID Extension. This is implemented here. When DisplayID is stored in its dedicated DDC device 0xA4, according to VESA E-DDC v1.3, different rules apply for the structure. This is not implemented here, as we don't currently use it, but the idea is you'd have a different call for beginning the iteration, for example simply: displayid_iter_begin(displayid, &iter); instead of displayid_iter_edid_begin(), and everything else would be hidden away in the iterator functions. v2: - sizeof(struct displayid_block) -> sizeof(*block) (Ville) - remove __ prefix from displayid_iter_block Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/da3dead1752ab16c061f7bd248ac1a4268f7fefb.1617024940.git.jani.nikula@intel.com

To support framebuffer layouts that are not in this layout add a logic that pads the tile rows to the POT aligned size.

2021-03-29drm/i915: Simplify copying the FB view state to the plane stateImre Deak
Instead of copying separately the GTT remapped and color plane view info from the FB to the plane state, do this by copying the whole intel_fb_view struct. For this we make sure the FB view state is fully inited (that is also including the view type) already during FB creation, so this init is not required during atomic check time. This also means the we don't need to reset the unused color plane info during atomic check, as these are already reset during FB creation. I noticed that initial FBs will only work atm if they are page aligned (which BIOS most probably always ensures), but add a comment to sanitize this part once. Also we won't disable the plane if get_initial_plane_config() failed for some reason (for instance due to unsupported rotation), add a TODO: comment for this too.

2021-03-29drm/i915: Unify the FB and plane state view information into one structImre Deak
To allow the simplification of FB/plane view computation in the follow-up patches, unify the corresponding state in the intel_framebuffer and intel_plane_state structs into a new intel_fb_view struct. This adds some overhead to intel_framebuffer as the rotated view will have now space for 4 color planes instead of the required 2 and it'll also contain the unused offset for each color_plane info. Imo this is an acceptable trade-off to get a simplified way of the remap computation. Use the new intel_fb_view struct for the FB normal view as well, so (in the follow-up patches) we can remove the special casing for normal view calculation wrt. the calculation of remapped/rotated views. This also adds an overhead to the intel_framebuffer struct, as the gtt remap info and per-color plane offset/pitch is not required for the normal view, but imo this is an acceptable trade-off as above. The per-color plane pitch filed will be used by a follow-up patch, so we can retrieve the pitch for each view in the same way. No functional changes in this patch. v2: - Make the patch have _no functional change_.

2021-03-29drm/i915: Fix rotation setup during plane HW readoutImre Deak
The HW plane state is cleared and inited after we store the rotation to it, so store it instead to the uapi state to match what we do with all other plane state until intel_plane_copy_uapi_to_hw_state() is called. Rotation for initial FBs is not supported atm, but let's still fix the plane state setup here. While at it remove the redundant intel_state->uapi.src/dst init, which will be done in intel_plane_copy_uapi_to_hw_state(). v2: Remove redundant intel_state->uapi.src/dst init.

2021-03-29drm/i915: Stop adding planes to the commit needlesslyVille Syrjälä
The dbuf bandwidth calculations don't need the planes to be added to the state. Each plane's data rate has already been precalculated and stored in the crtc state, and that with the dbuf slice usage for each plane is all the dbuf bandwidth code needs to figure out what the minimum cdclk is. What we're trying to do here is make sure each plane recalculates its minimum cdclk (ie. plane->min_cdclk()) on those platforms where the number of active planes affects the result of said calculation. Nothing to do with any dbuf cdclk requirements. Not sure if we had stuff in slightly different order or what, but at least in the current scheme this is not necessary.

2021-03-29drm: bridge/panel: Cleanup connector on bridge detachPaul Cercueil
If we don't call drm_connector_cleanup() manually in panel_bridge_detach(), the connector will be cleaned up with the other DRM objects in the call to drm_mode_config_cleanup(). However, since our drm_connector is devm-allocated, by the time drm_mode_config_cleanup() will be called, our connector will be long gone. Therefore, the connector must be cleaned up when the bridge is detached to avoid use-after-free conditions. v2: Cleanup connector only if it was created v3: Add FIXME v4: (Use connector->dev) directly in if() block Fixes: 13dfc0540a57 ("drm/bridge: Refactor out the panel wrapper from the lvds-encoder bridge.")
