accel/ivpu: Fix deadlock in context_xa

2024-04-08T08:55:01Z

ivpu_device->context_xa is locked both in kernel thread and IRQ context. It requires XA_FLAGS_LOCK_IRQ flag to be passed during initialization otherwise the lock could be acquired from a thread and interrupted by an IRQ that locks it for the second time causing the deadlock. This deadlock was reported by lockdep and observed in internal tests.

accel/ivpu: Return max freq for DRM_IVPU_PARAM_CORE_CLOCK_RATE

2024-04-08T08:54:21Z

DRM_IVPU_PARAM_CORE_CLOCK_RATE returns current NPU frequency which could be 0 if device was sleeping. This value isn't really useful to the user space, so return max freq instead which can be used to estimate NPU performance.

accel/ivpu: Improve clarity of MMU error messages

2024-04-08T08:54:21Z

This patch improves readability and clarity of MMU error messages. Previously, the error strings were somewhat confusing and could lead to ambiguous interpretations, making it difficult to diagnose issues.

accel/ivpu: Put NPU back to D3hot after failed resume

2024-04-08T08:54:21Z

Put NPU in D3hot after ivpu_resume() fails to power up the device. This will assure that D3->D0 power cycle will be performed before the next resume and also will minimize power usage in this corner case.

Pull power management updates from Rafael Wysocki: "From the functional perspective, the most significant change here is the addition of support for Energy Models that can be updated dynamically at run time. There is also the addition of LZ4 compression support for hibernation, the new preferred core support in amd-pstate, new platforms support in the Intel RAPL driver, new model-specific EPP handling in intel_pstate and more. Apart from that, the cpufreq default transition delay is reduced from 10 ms to 2 ms (along with some related adjustments), the system suspend statistics code undergoes a significant rework and there is a usual bunch of fixes and code cleanups all over.
