2025-06-04drm/i915/display: Fix u32 overflow in SNPS PHY HDMI PLL setupDibin Moolakadan Subrahmanian
When configuring the HDMI PLL, calculations use DIV_ROUND_UP_ULL and DIV_ROUND_DOWN_ULL macros, which internally rely on do_div. However, do_div expects a 32-bit (u32) divisor, and at higher data rates, the divisor can exceed this limit. This leads to incorrect division results and ultimately misconfigured PLL values. This fix replaces do_div calls with div64_base64 calls where diviser can exceed u32 limit.

2025-06-02drm/i915/guc: Handle race condition where wakeref count drops below 0Jesus Narvaez
There is a rare race condition when preparing for a reset where guc_lrc_desc_unpin() could be in the process of deregistering a context while a different thread is scrubbing outstanding contexts and it alters the context state and does a wakeref put. Then, if there is a failure with deregister_context(), a second wakeref put could occur. As a result the wakeref count could drop below 0 and fail an INTEL_WAKEREF_BUG_ON() check. Therefore if there is a failure with deregister_context(), undo the context state changes and do a wakeref put only if the context was set to be destroyed earlier. v2: Expand comment to better explain change.

Similar to the changes made for VCN v4.0.5 where readback to post the writes to avoid race with the doorbell, the addition of register readback support in other VCN versions is intended to prevent potential race conditions, even though such issues have not been observed yet.

This reverts commit d6e020819612a4a06207af858e0978be4d3e3140. The IS_DGFX check was put in place because error capture of buffer objects is expected to be broken on devices with VRAM. Userspace fix[1] to the impacted media driver has been submitted, merged and a new driver release is out as 25.2.3 where the capture flag is dropped on DG1 thus unblocking the usage of media driver on DG1.

2025-05-27drm/i915/gem: Allow EXEC_CAPTURE on recoverable contexts on DG1Ville Syrjälä
The intel-media-driver is currently broken on DG1 because it uses EXEC_CAPTURE with recovarable contexts. Relax the check to allow that.

2025-05-26drm/i915/dp: Fix the enabling/disabling of audio SDP splittingImre Deak
Adjust the enabling/disabling steps of the DP audio SDP splitting according to a recent Bspec update. This moves the enabling to the audio codec enable sequence after the transcoder is enabled and disables SDP splitting explicitly during the audio disable sequence. Bspec requires waiting for a vblank event after the transcoder is enabled and before SDP splitting is enabled. There is no need for an explicit wait for this, since after the transcoder is enabled this vblank event is guaranteed to have happened via a flip done wait (see intel_atomic_commit_tail() -> drm_atomic_helper_wait_for_flip_done()). The bspec update is for LNL+ only, but the HW team clarified that this has been always the intended sequence on all platforms and bspec will be updated everywhere accordingly. The way SDP splitting was originally enabled matched the version of bspec at that time. Adding here the Fixes: line still, since this change fixes a FIFO underrun on PTL during output enabling when DSC is enabled.
