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.

2025-05-16gpu: Switch to irq_domain_create_linear()Jiri Slaby (SUSE)
irq_domain_add_linear() is going away as being obsolete now. Switch to the preferred irq_domain_create_linear(). That differs in the first parameter: It takes more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).

2025-05-12drm/msm/dp: Introduce link training per-segment for LTTPRsAleksandrs Vinarskis
DisplayPort requires per-segment link training when LTTPR are switched to non-transparent mode, starting with LTTPR closest to the source. Only when each segment is trained individually, source can link train to sink. Implement per-segment link traning when LTTPR(s) are detected, to support external docking stations. On higher level, changes are: * Pass phy being trained down to all required helpers * Run CR, EQ link training per phy * Set voltage swing, pre-emphasis levels per phy Since at least some LTTPRs (eg. Parade PS8830) do not correctly report voltage-swing, pre-emphasis level 3 support, always assume level 3 is supported. This is permitted under DP 2.1(a) section 3.6.7.2 stating that LTTPR shall set its transmitter levels as close as possible to those requested by the DPTX, if the DPTX sets the voltage swing or pre-emphasis to a level that the LTTPR does not support. It shall be noted that LTTPR’s level choosing is implementation-specific. This ensures successful link training both when connected directly to the monitor (single LTTPR onboard most X1E laptops) and via the docking station (at least two LTTPRs).

2025-05-10drm/msm/adreno: Remove MODULE_FIRMWARE()'sRob Clark
The driver handles the case where gpu fw is not in the initrd. OTOH it doesn't always handle the case where _some_ fw is in the initrd, but others are not. In particular the zap fw tends to be signed with an OEM specific key, so the paths/names differ across devices with the same SoC/GPU, so we cannot sanely list them with MODULE_FIRMWARE(). So MODULE_FIRMWARE() just ends up causing problems without actually solving anything. Remove them!

2025-05-04drm/msm: Be more robust when HFI response times outConnor Abbott
If the GMU takes too long to respond to an HFI message, we may return early. If the GMU does eventually respond, and then we send a second message, we will see the response for the first, throw another error, and keep going. But we don't currently wait for the interrupt from the GMU again, so if the second response isn't there immediately we may prematurely return. This can cause a continuous cycle of missed HFI messages, and for reasons I don't quite understand the GMU does not shut down properly when this happens. Fix this by waiting for the GMU interrupt when we see an empty queue. If the GMU never responds then the queue really is empty and we quit. We can't wait for the interrupt when we see a wrong response seqnum because the GMU might have already queued both responses by the time we clear the interrupt the first time so we do need to check the queue before waiting on the interrupt again.

2025-05-04drm/msm/gpu: Fix crash when throttling GPU immediately during bootStephan Gerhold
There is a small chance that the GPU is already hot during boot.

At this point we haven't initialized the GMU at all yet, so we cannot read the GMU registers inside a6xx_gpu_busy(). A similar issue was fixed before in commit 6694482a70e9 ("drm/msm: Avoid unclocked GMU register access in 6xx gpu_busy"): msm_devfreq_init() does call devfreq_suspend_device(), but unlike msm_devfreq_suspend(), it doesn't set the df->suspended flag accordingly. This means the df->suspended flag does not match the actual devfreq state after initialization and msm_devfreq_get_dev_status() will end up accessing GMU registers, causing the crash. Fix this by setting df->suspended correctly during initialization.
