2021-06-28drm/i915/dsc: abstract helpers to get bigjoiner primary/secondary crtcJani Nikula4-16/+40
Add a single point of truth for figuring out the primary/secondary crtc for bigjoiner instead of duplicating the magic pipe +/- 1 in multiple places. Also fix the pipe validity checks to properly take non-contiguous pipes into account. The current checks may theoretically overflow i915->pipe_to_crtc_mapping[pipe], albeit with a warning, due to fused off pipes, as INTEL_NUM_PIPES() returns the actual number of pipes on the platform, and the check is for INTEL_NUM_PIPES() == pipe + 1. Prefer primary/secondary terminology going forward. v2: - Improved abstractions for pipe validity etc. Fixes: 8a029c113b17 ("drm/i915/dp: Modify VDSC helpers to configure DSC for Bigjoiner slave") Fixes: d961eb20adb6 ("drm/i915/bigjoiner: atomic commit changes for uncompressed joiner") Cc: Animesh Manna <animesh.manna@intel.com> Cc: Manasi Navare <manasi.d.navare@intel.com> Cc: Vandita Kulkarni <vandita.kulkarni@intel.com> Reviewed-by: Manasi Navare <manasi.dl.navare@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210610090528.20511-1-jani.nikula@intel.com (cherry picked from commit 17203224f0536cf223dc5789028d04a768d96ec3) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

This introduces the following function that can exit and activate a psr source when intel_psr is already enabled. - intel_psr_pause(): Pause current PSR. It deactivates current psr state. - intel_psr_resume(): Resume paused PSR. It activates paused psr state. v2: Address Jose's review comment. - Remove unneeded changes around the intel_psr_enable(). - Add intel_psr_post_exit() which processes waiting until PSR is idle and WA for SelectiveFetch. v3: Address Jose's review comment. - Rename intel_psr_post_exit() to intel_psr_wait_exit_locked(). - Move WA_1408330847 to intel_psr_disable_locked() - If the PSR is paused by an explicit intel_psr_paused() call, make the intel_psr_flush() not to activate PSR. v4: Address Jose's review comment. - In order to avoid the scenario of PSR is not active but there is a scheduled psr->work, it changes the check routine of intel_psr_pause() for PSR's enablement from "psr->active" to "psr->enable".

2021-06-07drm/i915/display: Fix fastsets involving PSRJosé Roberto de Souza1-5/+5
Commit 78b772e1a01f ("drm/i915/display: Fill PSR state during hardware configuration read out") is not allowing fastsets to happen when PSR states changes but PSR is a feature that can be enabled and disabled during fastsets. So here moving the PSR pipe conf checks to a block that is only executed when checking if HW state matches with requested state, not during the phase where it checks if fastset is possible or not. There still a state mismatch not allowing fastsets between states turning off or on PSR because of crtc_state->infoframes.enable BIT(DP_SDP_VSC) but at least for now it will allow a fastset between PSR1 <-> PSR2, that is a case heavilly used by CI due to pipe CRC not work with PSR2, but the remaning issue will be fixed in a future patch.

However if the kernel is not configured with fbcon then it should be possible to relax this, since unlike with fbcon the display server shouldn't preserve it when later replacing it, and so we should be able to re-use the stolen memory for fbc and friends.

2021-05-26drm/i915/xelpd: Enhanced pipe underrun reportingMatt Roper1-6/+51
XE_LPD brings enhanced underrun recovery: the hardware can somewhat mitigate underruns by using an interpolated replacement pixel (soft underrun) or the previous pixel (hard underrun). Furthermore, underruns can now be caused downstream by the port, even if the pipe itself is operating properly. The interrupt register and PIPE_STATUS register give us extra bits to recognize hard/soft underruns and determine whether the underrun was caused by the port, so we'll use that information to print some more descriptive errors when underruns occur. v2: - Keep ICL's PIPE_STATUS defined separately from the old GMCH pipe status register. (Ville) - Only read/clear the PIPE_STATUS register on platforms with display ver >= 11. (Lucas) v3: - Actually enable+unmask all the new underrun interrupts, clear stale bits out from PIPE_STATUS before enabling the interrupts, report all FIFO underruns errors at once, rename a bunch of stuff to unconfuse vs. PIPESTAT.

2021-05-25drm/i915/adlp: Require DPT FB CCS color planes to be 2MB alignedImre Deak1-2/+11
All DPT FB color plane surface base addresses must be 2MB aligned. On ADL_P this means that the offsets in CCS FB object must be also 2MB aligned. Adjusting unaligned offsets for these FBs during commit time (compensating with the x/y offsets) doesn't work, since the big alignment would most probably lead to an x/y offset mismatch error between the main and CCS planes. We can overcome this limitation by remapping CCS FBs, so that each color plane is at an aligned offset, leaving x/y for each plane unadjusted during commit and so not causing an x/y mismatch error. However remapping for CCS FBs will be done as a follow-up, so for now require that user space allocates the FB obj with properly aligned planes. v2: s/SZ_2M/512*4k/ for clarity.

2021-05-21drm/i915: Reenable LTTPR non-transparent LT mode for DPCD_REV<1.4Imre Deak1-38/+33
The driver currently disables the LTTPR non-transparent link training mode for sinks with a DPCD_REV<1.4, based on the following description of the LTTPR DPCD register range in DP standard 2.0 (at the 0xF0000 register description): "" LTTPR-related registers at DPCD Addresses F0000h through F02FFh are valid only for DPCD r1.4 (or higher). """ The transparent link training mode should still work fine, however the implementation for this in some retimer FWs seems to be broken, see the References: link below. After discussions with DP standard authors the above "DPCD r1.4" does not refer to the DPCD revision (stored in the DPCD_REV reg at 0x00000), rather to the "LTTPR field data structure revision" stored in the 0xF0000 reg. An update request has been filed at vesa.org (see wg/Link/documentComment/3746) for the upcoming v2.1 specification to clarify the above description along the following lines: """ LTTPR-related registers at DPCD Addresses F0000h through F02FFh are valid only for LT_TUNABLE_PHY_REPEATER_FIELD_DATA_STRUCTURE_REV 1.4 (or higher) """ Based on my tests Windows uses the non-transparent link training mode for DPCD_REV==1.2 sinks as well (so presumably for all DPCD_REVs), and forcing it to use transparent mode on ICL/TGL platforms leads to the same LT failure as reported at the References: link. Based on the above let's assume that the transparent link training mode is not well tested/supported and align the code to the correct interpretation of what the r1.4 version refers to.
