2024-06-14accel/ivpu: Implement DCT handlingJacek Lawrynowicz1-1/+9
When host system is under heavy load and the NPU is already running on the lowest frequency, PUNIT may request Duty Cycle Throttling (DCT). This will further reduce NPU power usage. PUNIT requests DCT mode using Survabilty IRQ and mailbox register. The driver then issues a JSM message to the FW that enables the DCT mode. If the NPU resets while in DCT mode, the driver request DCT mode during FW boot. Also add debugfs "dct" file that allows to set arbitrary DCT percentage, which is used by driver tests.

2024-05-17accel/ivpu: Split IP and buttress codeWachowski, Karol1-7/+6
The NPU device consists of two parts: NPU buttress and NPU IP. Buttress is a platform specific part that integrates the NPU IP with the CPU. NPU IP is the platform agnostic part that does the inference. This separation enables support for multiple platforms using a single NPU IP, so for example NPU IP 37XX could be integrated into MTL and LNL platforms.

2024-05-15accel/ivpu: Share NPU busy time in sysfsTomasz Rusinowicz1-0/+2
The driver tracks the time spent by NPU executing jobs and shares it through sysfs `npu_busy_time_us` file. It can be then used by user space applications to monitor device utilization. NPU is considered 'busy' starting with a first job submitted to firmware and ending when there is no more jobs pending/executing.

2023-09-04accel/ivpu: Remove duplicated error messagesJacek Lawrynowicz1-39/+13
Reduce the number of error messages per single failure in ivpu_dev_init() and ivpu_probe(). Most error messages are already printed by functions called from ivpu_dev_init(). Add missed error prints in ivpu_ipc_init() and ivpu_mmu_context_init().

Add new dma range and change naming convention for virtual address memory ranges managed by KMD. New available ranges are named as follows: * global range - global context accessible by FW * aliased range - user context accessible by FW * dma range - user context accessible by DMA * shave range - user context accessible by shaves * global shave range - global context accessible by shave nn Signed-off-by: Karol Wachowski <karol.wachowski@linux.intel.com> Reviewed-by: Stanislaw Gruszka <stanislaw.gruszka@linux.intel.com> Signed-off-by: Stanislaw Gruszka <stanislaw.gruszka@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230731161258.2987564-6-stanislaw.gruszka@linux.intel.com

Given that VPU generation can be used by multiple platforms, driver should use VPU IP generation names instead of a platform. Change naming for functions and registries.
