* accel/ivpu: Fix deadlock in context_xaJacek Lawrynowicz2024-04-081-1/+1
| | | | | | | | | | | | | | | 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_RATEJacek Lawrynowicz2024-04-084-20/+17
| | | | | | | | | | | | | 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: Put NPU back to D3hot after failed resumeJacek Lawrynowicz2024-04-081-0/+1
| | | | | | | | | | | | 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.

This could lead to values wrapping around and a smaller allocation being made than the caller was expecting. Using those allocations could lead to linear overflows of heap memory and other misbehaviors. So, use the purpose specific kcalloc() function instead of the argument size * count in the kzalloc() function.
