Pull drm updates from Dave Airlie: "As part of building up nova-core/nova-drm pieces we've brought in some rust abstractions through this tree, aux bus being the main one, with devres changes also in the driver-core tree. Along with the drm core abstractions and enough nova-core/nova-drm to use them. This is still all stub work under construction, to build the nova driver upstream. The other big NVIDIA related one is nouveau adds support for Hopper/Blackwell GPUs, this required a new GSP firmware update to 570.144, and a bunch of rework in order to support multiple fw interfaces. There is also the introduction of an asahi uapi header file as a precursor to getting the real driver in later, but to unblock userspace mesa packages while the driver is trapped behind rust enablement. Otherwise it's the usual mixture of stuff all over, amdgpu, i915/xe, and msm being the main ones, and some changes to vsprintf. new drivers: - bring in the asahi uapi header standalone - nova-drm: stub driver rust dependencies (for nova-core): -

2025-05-22drm/i915/dp_mst: Work around Thunderbolt sink disconnect after ↵Imre Deak
SINK_COUNT_ESI read Due to a problem in the iTBT DP-in adapter's firmware the sink on a TBT link may get disconnected inadvertently if the SINK_COUNT_ESI and the DP_LINK_SERVICE_IRQ_VECTOR_ESI0 registers are read in a single AUX transaction. Work around the issue by reading these registers in separate transactions. The issue affects MTL+ platforms and will be fixed in the DP-in adapter firmware, however releasing that firmware fix may take some time and is not guaranteed to be available for all systems. Based on this apply the workaround on affected platforms. See HSD #13013007775. v2: Cc'ing Mika Westerberg.

limit on MST Atm, on an MST link in DSC mode intel_dp_compute_config_link_bpp_limits() calculates the maximum link bpp limit using the MST root connector's DSC capabilities. That's not correct in general: the decompression could be performed by a branch device downstream of the root branch device or the sink itself.

2025-05-09drm/i915/dp: Fix determining SST/MST mode during MTP TU state computationImre Deak
Determining the SST/MST mode during state computation must be done based on the output type stored in the CRTC state, which in turn is set once based on the modeset connector's SST vs. MST type and will not change as long as the connector is using the CRTC. OTOH the MST mode indicated by the given connector's intel_dp::is_mst flag can change independently of the above output type, based on what sink is at any moment plugged to the connector. Fix the state computation accordingly.

2025-05-07drm/i915/irq: move i915->irq_lock to display->irq.lockJani Nikula
Observe that i915->irq_lock is no longer used to protect anything outside of display. Make it a display thing. This allows us to remove the ugly #define irq_lock irq.lock hack from xe compat header. Note that this is slightly more subtle than it first looks. For i915, there's no functional change here. The lock is moved. However, for xe, we'll now have *two* locks, xe->irq.lock and display->irq.lock. These should protect different things, though. Indeed, nesting in the past would've lead to a deadlock because they were the same lock. With the i915 references gone, we can make a handful more files independent of i915_drv.h.

The gsc_hdcp_ops is duplicated and initialized exactly the same way in two different places (for i915 and xe), and requires forward declarations for all the hooks. Deduplicate, and make the functions static. There are slight differences in the i915 and xe implementations of intel_hdcp_gsc_init() and intel_hdcp_gsc_fini(). Take the best of both, and improve.
