2025-03-27drm/i915/dsi: let HW maintain the HS-TRAIL timingWilliam Tseng
This change is to avoid over-specification of the TEOT timing parameter, which is derived from software in current design. Supposed that THS-TRAIL and THS-EXIT have the minimum values, i.e., 60 and 100 in ns. If SW is overriding the HW default, the TEOT value becomes 150 ns, approximately calculated by the following formula. DIV_ROUND_UP(60/50)*50 + DIV_ROUND_UP(100/50))*50/2, where 50 is LP Escape Clock time in ns. The TEOT value 150 ns is larger than the maximum value, around 136 ns if UI is 1.8ns, (105 ns + 12*UI, defined by MIPI DPHY specification). However, the TEOT value will meet the specification if THS-TRAIL is set to the HW default, instead of software overriding. The timing change is made for both data lane and clock lane. v1: initial version. v2: change clock lane dphy timings. v3: remove calculation of trail cnt. v4: rebase.

2025-03-25drm/i915/vrr: Set trans_vrr_ctl in intel_vrr_set_transcoder_timings()Ankit Nautiyal
We now always set vrr.flipline, vmin, and vmax for all platforms that support VRR. Therefore, we should set all TRANS_VRR_CTL bits except VRR_ENABLE. Without this, the readback for these bits will fail because we only read vrr.flipline, vmin, and vmax if TRANS_VRR_CTL has the FLIPLINE_EN bit set. For platforms that always have the VRR Timing Generator enabled, the FLIPLINE_EN bit is always set in TRANS_VRR_CTL during intel_transcoder_vrr_enable(). However, for the remaining platforms (that do not always have the VRR Timing Generator enabled) if a full modeset doesn't occur and VRR is not enabled, the bit is not set. This results in a mismatch between the software state and hardware state because the software state expects VRR timings like flipline, vmin, and vmax to be set, but the readout for these doesn't happen since the FLIPLINE_EN bit is not set in TRANS_VRR_CTL. To avoid this mismatch, write trans_vrr_ctl in intel_vrr_set_transcoder_timings() even when VRR is not enabled for platforms that do not have the VRR Timing Generator always enabled.

2025-03-25drm/i915/vrr: Always use VRR timing generator for PTL+Ankit Nautiyal
Currently, the VRR timing generator is used only when VRR is enabled by userspace for sinks that support VRR. Starting with PTL+, gradually move away from the legacy timing generator and use the VRR timing generator for both variable and fixed timings. Note: For platforms where we always enable the VRR timing generator, the LRR fastset is not allowed to avoid live programming of vrr.guardband with VRR TG enabled. This effectively breaks the LRR fastset functionality for these platforms and needs to be addressed. v2: Use this for PTL for now to avoid losing LRR fastset for older platforms.

For older platforms the vrr.guardband change happens when VRR Timing generator is off.

2025-03-25drm/i915/dp_mst: Fix side-band message timeouts due to long PPS delaysImre Deak
The Panel Power Sequencer lock held on an eDP port (a) blocks a DP AUX transfer on another port (b), since the PPS lock is device global, thus shared by all ports. The PPS lock can be held on port (a) for a longer period due to the various PPS delays (panel/backlight on/off, power-cycle delays). This in turn can cause an MST down-message request on port (b) time out, if the above PPS delay defers the handling of the reply to the request by more than 100ms: the MST branch device sending the reply (signaling this via the DP_DOWN_REP_MSG_RDY flag in the DP_DEVICE_SERVICE_IRQ_VECTOR DPCD register) may cancel the reply (clearing DP_DOWN_REP_MSG_RDY and the reply message buffer) after 110 ms, if the reply is not processed by that time. Avoid MST down-message timeouts described above, by locking the PPS state for AUX transfers only if this is actually required: on eDP ports, where the VDD power depends on the PPS state and on all DP and eDP ports on VLV/CHV, where the PPS is a pipe instance and hence a modeset on any port possibly affecting the PPS state. v2: Don't move PPS locking/VDD enabling to a separate function.

2025-03-24drm/i915/fbc: update the panel_replay dependency in fbc wa'sVinod Govindapillai
There are two panel_replay scenarios fbc wa need to be aware of, panel replay with and without selective update capability. Panel replay without selective update don't have any fbc wa. So keep the fbc psr1 wa as it is. The current fbc psr2 wa is mainly about selective fetch and we need to apply the fbc wa if selective fetch is on - irrespective of panel replay. Hence we can't exclude panel replay from the fbc psr2 wa. v1: keep panel_replay exclusion in PSR1 case (Jouni) Patch description updated Bspec: 66624, 50442 Signed-off-by: Vinod Govindapillai <vinod.govindapillai@intel.com> Reviewed-by: Jouni Högander <jouni.hogander@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250321094529.197397-3-vinod.govindapillai@intel.com

2025-03-24drm/i915/dmc: Create debugfs entry for dc6 counterMohammed Thasleem
Starting from MTL we don't have a platform agnostic way to validate DC6 state due to dc6 counter has been removed to validate DC state. The goal is to validate that the display HW can reach the DC6 power state. There is no HW DC6 residency counter (and there wasn't such a counter earlier either), so an alternative way is required. According to the HW team the display driver has programmed everything correctly in order to allow the DC6 power state if the DC5 power state is reached (indicated by the HW DC5 residency counter incrementing) and DC6 is enabled by the driver. Driver could take a snapshot of the DC5 residency counter right after it enables DC6 (dc5_residency_start) and increment the SW DC6 residency counter right before it disables DC6 or when user space reads the DC6 counter. So the driver would update the counter at these two points in the following way: dc6_residency_counter += dc5_current_count - dc5_start_count v2: Update the discription. (Imre) Read dc5 count during dc6 enable and disable then and update dc6 residency counter. (Imre) Remove variable from dmc structure. (Jani) Updated the subject title. v3: Add i915_power_domains lock to updated dc6 count in debugfs. (Imre) Use flags to check dc6 enable/disable states. (Imre) Move the display version check and counter read/update to a helper. (Imre) Resize the variable length. (Rodrigo) Use old dc6 debugfs entry for every platform. (Rodrigo) v4: Remove superfluous whitespace. (Jani) Read DMC registers in intel_dmc.c (Jani) Rename dc6_en_dis to dc6_enabled and change its type to bool. (Jani) Rename update_dc6_count and move it to intel_dmc.c (Jani) Rename dc6_en_dis to start_tracking. (Imre) Have lock for dc6 state read aswelll. (Imre) Keep the existing way print 'DC5 -> DC6 count' along with new 'DC6 Allowed Count' print. (Imre) Add counters in intel_dmc struct. (Imre) Have interface to return dc6 allowed count. (Imre) Rename dc6_count to dc6_allowed_count. (Rodrigo) v5: Rename counters and move in to dc6_allowed structure. (Imre) Order declaration lines in decreasing line length. (Imre) Update start_tacking logic. (Imre) Move get couner inside lock and DISPLAY_VER code to helper. (Imre) v6: Change intel_dmc_get_dc6_allowed_count return type to bool. (Imre) Update debugfs print to better allien with old print. (Imre) Remove braces at if/else for signle line statements. (Imre) v7: Remove in line variable declaration. (Imre) v8: Rebase the changes.
