2021-03-31drm/i915/hdcp: Add DP HDCP2.2 timeout to read entire msgAnshuman Gupta
As documented in HDCP 2.2 DP Errata spec transmitter should abort the authentication protocol in case transmitter has not received the entire {AKE_Send_Cert, AKE_Send_H_prime, AKE_Send_Paring_Info} msg within {110,7,5} miliseconds. Adding above msg timeout values and aborting the HDCP authentication in case it timedout to read entire msg. https://www.digital-cp.com/sites/default/files/HDCP%202_2_DisplayPort_Errata_v3_0.pdf v2: - Removed redundant variable msg_can_timedout.

2021-03-29drm/i915: Add support for FBs requiring a POT stride alignmentImre Deak
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().

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: 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/i915: switch KBL to the new stepping schemeJani Nikula
Add new symbolic names for revision ids, and convert KBL revids to use them via the new stepping check macros.

2021-03-29drm/i915: add new helpers for accessing stepping infoJani Nikula
Add new runtime info field for stepping. Add new helpers for accessing them. As we'll be switching platforms over to the new scheme incrementally, check for non-initialized steppings. In case a platform does not have separate display and gt steppings, it's okay to use a common shorthand. However, in this case the display stepping must not be initialized, and gt stepping is the single point of truth. v3: Remove IS_STEP() (José) v2: Rename stepping->step Reviewed-by: José Roberto de Souza <jose.souza@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/bb4275733fa390ea3dbf6f62794d55b616665230.1616764798.git.jani.nikula@intel.com
