2025-07-06accel/ivpu: Make command queue ID allocated on XArrayKarol Wachowski1-1/+6
[ Upstream commit 76ad741ec7349bb1112f3a0ff27adf1ca75cf025 ] Use XArray for dynamic command queue ID allocations instead of fixed ones. This is required by upcoming changes to UAPI that will allow to manage command queues by user space instead of having predefined number of queues in a context.

2025-05-09accel/ivpu: Abort all jobs after command queue unregisterKarol Wachowski1-0/+2
commit 5bbccadaf33eea2b879d8326ad59ae0663be47d1 upstream. With hardware scheduler it is not expected to receive JOB_DONE notifications from NPU FW for the jobs aborted due to command queue destroy JSM command. Remove jobs submitted to unregistered command queue from submitted_jobs_xa to avoid triggering a TDR in such case. Add explicit submitted_jobs_lock that protects access to list of submitted jobs which is now used to find jobs to abort. Move context abort procedure to separate work queue not to slow down handling of IPCs or DCT requests in case where job abort takes longer, especially when destruction of the last job of a specific context results in context release.

2025-05-09accel/ivpu: Use xa_alloc_cyclic() instead of custom functionKarol Wachowski1-2/+2
commit ae7af7d8dc2a13a427aa90d003fe4fb2c168342a upstream. Remove custom ivpu_id_alloc() wrapper used for ID allocations and replace it with standard xa_alloc_cyclic() API. The idea behind ivpu_id_alloc() was to have monotonic IDs, so the driver is easier to debug because same IDs are not reused all over. The same can be achieved just by using appropriate Linux API.

2023-10-30accel/ivpu: Add support for delayed D0i3 entry messageAndrzej Kacprowski1-3/+7
Currently the VPU firmware prepares for D0i3 every time the VPU is entering D0i2 Idle state. This is not optimal as we might not enter D0i3 every time we enter D0i2 Idle and this preparation is quite costly. This optimization moves D0i3 preparation to a dedicated message sent from the host driver only when the driver is about to enter D0i3 - this reduces power consumption and latency for certain workloads, for example audio workloads that submit inference every 10 ms. The VPU needs non zero time to enter IDLE state after responding to D0i3 entry message. If the driver does not wait for the VPU to enter IDLE state it could cause warm boot failures.

2023-09-04accel/ivpu: Initialize context with SSID = 1Karol Wachowski1-5/+7
Context with SSID = 1 is reserved and accesses on that context happen only when context is uninitialized on the VPU side. Such access triggers MMU fault (0xa) "Invalid CD Fetch", which doesn't contain any useful information besides context ID. This commit will change that state, now (0x10) "Translation fault" will be triggered and accessed address will shown in the log.

MTL C0 stepping fixed issue related to butrress interrupt status clearing, to clear an interrupt status it is required to write 1 to specific status bit field. This allows to execute read, modify and write routine. Writing 0 will not clear the interrupt and will cause interrupt storm.

The SSID=1 is used by the firmware as default value in case SSID mapping is not initialized. This allows detecting use of miss-configured memory contexts. The future FW versions may not allow using SSID=1. SSID=65 is valid value, number of contexts are limited by number of available command queues, but SSID can be any u16 value.

2023-01-19accel/ivpu: Add command buffer submission logicJacek Lawrynowicz1-0/+5
Each of the user contexts has two command queues, one for compute engine and one for the copy engine. Command queues are allocated and registered in the device when the first job (command buffer) is submitted from the user space to the VPU device. The userspace provides a list of GEM buffer object handles to submit to the VPU, the driver resolves buffer handles, pins physical memory if needed, increments ref count for each buffer and stores pointers to buffer objects in the ivpu_job objects that track jobs submitted to the device. The VPU signals job completion with an asynchronous message that contains the job id passed to firmware when the job was submitted. Currently, the driver supports simple scheduling logic where jobs submitted from user space are immediately pushed to the VPU device command queues. In the future, it will be extended to use hardware base scheduling and/or drm_sched.
