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.

Currently the FRL training mode (Concurrent, Sequential) and training type (Normal, Extended) are not defined properly and are passed as bool values in drm_helpers for pcon configuration for FRL training. This patch: -Add register masks for Sequential and Normal FRL training options. -Fixes the drm_helpers for FRL Training configuration to use the appropriate masks. -Modifies the calls to the above drm_helpers in i915/intel_dp as per the above change. v2: Re-used the register masks for these options, instead of enum.

Add selftests to test the POT stride padding functionality added in the previous patch. Signed-off-by:
Imre Deak <imre.deak@intel.com> 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(). (Ville) - Pass pitch_tiles as unsigned int. v3: - Drop unintentional s/plane_state->rotation/plane_config->rotation/ change. Signed-off-by:

Save some place in the GTT VMAs by using a u16 instead of unsigned int to store the view dimensions. The maximum FB stride is 256kB which is 4096 tiles in the worst case (yf-tiles), the maximum FB height is 16k pixels, which is 16384 tiles in the worst case (linear 4x1 tiled FB). v2: - Fix worst case tile height formula in commit log. (Ville) - Add an assign_chk_ovf helper to simplify the related assignments. v3: - Enclose params of the assign_chk_ovf macro in parentheses. Signed-off-by:

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.

Instead of special casing getting the pitch for the normal view, store it during FB creation to the FB normal view struct and retrieve it from there during atomic check, as it's done for the rotated view. A follow-up patch does the same for a new FB remapped view. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

Imre Deak authored
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_. (fix skl_check_nv12_aux_surface() and skl_check_main_surface()). - s/i915_color_plane_view::pitch/stride/ (Ville) Suggested-by:

Factor out to a new function the logic to calculate an FB plane's normal-view size. Instead of using intel_remapped_plane_info, which is related only to remapping, add a helper to get the tile pitch and rows for an FB plane, so these helpers can be used both by the normal size calculation and the remapping code. Also add a new fb_plane_view_dims struct in which we can pass around the view (either FB plane or plane source) and tile dimensions conveniently to functions calculating further view parameters. v2: - Add back the +1 tile adjustment for x!=0 in calc_plane_normal_size(). (Ville) - s/pages/tiles/ in calc_plane_normal_size(). (Ville) - Add a helper for the plane view width calculation. (Ville) - Return tiles as unsigned int from calc_plane_normal_size().

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. (Ville) Signed-off-by:

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.

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.

Update logic to program AUD_FREQ_CNTRL register based on new guidance. Earlier this register was configured by BIOS and driver discovered the value at init. This is no longer recommended and instead driver should set the values based on the hardware revision. Add the recommended values for all supported hardware. This change applies for all GEN12+ hardware. For TGL, some special case handling is needed to not break existing systems. Extend the debug print to also include values of the register as written by BIOS. This can help debug rare cases where BIOS has configured the link settings to incorrect values.

To optimize some task deferring it until runtime resume unless someone holds a runtime PM reference (because in this case the task can be done w/o the overhead of runtime resume), we have to use the runtime PM get-if-active logic: If the runtime PM usage count is 0 (and so get-if-in-use would return false) the runtime suspend handler is not necessarily called yet (it could be just pending), so the device is not necessarily powered down, and so the runtime resume handler is not guaranteed to be called. The fence revocation depends on the above deferral, so add a get-if-active helper and use it during fence revocation. v2: - Add code comment explaining the fence reg programming deferral logic to i915_vma_revoke_fence().
