Follow Bspec 31870 to set recommended tuning values for certain GT register. These values aren't workarounds per-se, but it's best to handle them in the same general area of the driver, especially since there may be real workarounds that update other bits of the same registers. At the moment the only value we need to worry about is the TDS_TIMER setting in FF_MODE2. This setting was previously described as "Wa_1604555607" on some platforms, but the spec tells us that we should continue to program this on all current gen12 platforms, even those that do not have that WA.

commit f0119514 ("drm/mediatek: mtk_dpi: Create connector for bridges") broke the display support for elm device since mtk_dpi calls drm_bridge_attach with the flag DRM_BRIDGE_ATTACH_NO_CONNECTOR while mtk_hdmi does not yet support this flag. Fix this by accepting DRM_BRIDGE_ATTACH_NO_CONNECTOR in bridge attachment. Implement the drm_bridge_funcs .detect() and .get_edid() operations, and call drm_bridge_hpd_notify() to report HPD. This provides the necessary API to support disabling connector creation. In addition, the field 'conn' is removed from the mtk_hdmi struct since mtk_hdmi don't create a connector. It is replaced with a pointer 'curr_conn' that points to the current connector which can be access through the global state. This patch is inspired by a similar patch for bridge/synopsys/dw-hdmi.c: commit ec971aaa ("drm: bridge: dw-hdmi: Make connector creation optional") But with the difference that in mtk-hdmi only the option of not creating a connector is supported.

The bridge operation '.enable' and the audio cb '.get_eld' access hdmi->conn. In the future we will want to support the flag DRM_BRIDGE_ATTACH_NO_CONNECTOR and then we will not have direct access to the connector. The atomic version '.atomic_enable' allows accessing the current connector from the state. This patch switches the bridge to the atomic version to prepare access to the connector in later patches.

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: -

Imre Deak authored
An upcoming platform has a restriction that the FB stride must be power-of-two aligned. To support framebuffer layouts that are not in this layout add a logic that pads the tile rows to the POT aligned size. The HW won't read the padding PTEs, so these don't have to point to an allocated address, or even have their valid flag set. So use a NULL PTE instead for instance the scratch page, which is simple and keeps the SG table compact. v2: - Simplify plane_view_dst_stride().

Imre Deak authored
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.
