drm-misc-next for v6.19-rc1:

UAPI Changes:
- Add userptr support to ivpu.
- Add IOCTL's for resource and telemetry data in amdxdna.

Core Changes:
- Improve some atomic state checking handling.
- drm/client updates.

This mitigation in QAIC is very effective. The same lprnet usecase that

generates 100k IRQs per second (per /proc/interrupts) is reduced to roughly 64

IRQs over 5 minutes while keeping the host system stable, and having the same

To support this fallback, we allow the case where only one MSI is able to be

allocated, and share that one MSI between MHI and the DBCs. The device detects

when only one MSI has been configured and directs the interrupts for the DBCs

to the interrupt normally used for MHI. Unfortunately this means that the

The implementation of NNC is split between the KMD (QAIC) and UMD. In general,

QAIC understands how to encode/decode NNC wire protocol, and elements of the
