2024-10-12accel/qaic: Fix the for loop used to walk SG tablePranjal Ramajor Asha Kanojiya2-4/+4
Only for_each_sgtable_dma_sg() should be used to walk through a SG table to grab correct bus address and length pair after calling DMA MAP API on a SG table as DMA MAP APIs updates the SG table and for_each_sgtable_sg() walks through the original SG table.

2024-10-11accel/ivpu: Prevent recovery invocation during probe and resumeKarol Wachowski3-38/+23
Refactor IPC send and receive functions to allow correct handling of operations that should not trigger a recovery process. Expose ivpu_send_receive_internal(), which is now utilized by the D0i3 entry, DCT initialization, and HWS initialization functions. These functions have been modified to return error codes gracefully, rather than initiating recovery. The updated functions are invoked within ivpu_probe() and ivpu_resume(), ensuring that any errors encountered during these stages result in a proper teardown or shutdown sequence. The previous approach of triggering recovery within these functions could lead to a race condition, potentially causing undefined behavior and kernel crashes due to null pointer dereferences.

2024-08-29dma-mapping: don't return errors from dma_set_max_seg_sizeChristoph Hellwig1-3/+1
A NULL dev->dma_parms indicates either a bus that is not DMA capable or grave bug in the implementation of the bus code. There isn't much the driver can do in terms of error handling for either case, so just warn and continue as DMA operations will fail anyway.

2024-08-26accel: Use XArray instead of IDR for minorsMichał Winiarski1-103/+7
Accel minor management is based on DRM (and is also using struct drm_minor internally), since DRM is using XArray for minors, it makes sense to also convert accel. As the two implementations are identical (only difference being the underlying xarray), move the accel_minor_* functionality to DRM.

2024-07-15accel/ivpu: Add missing MODULE_FIRMWARE metadataAlexander F. Lent1-0/+4
Modules that load firmware from various paths at runtime must declare those paths at compile time, via the MODULE_FIRMWARE macro, so that the firmware paths are included in the module's metadata. The accel/ivpu driver loads firmware but lacks this metadata, preventing dracut from correctly locating firmware files. Fix it.

2024-06-23accel/habanalabs: gradual sleep in polling memory macroDidi Freiman1-2/+9
It’s better to avoid long sleeps right from the beginning of the polling since the data may be available much sooner than the sleep period. Because polling host memory is inexpensive, this change gradually increases the sleep time up to the user-requested period.

2024-06-23accel/habanalabs: move heartbeat work initialization to early initTomer Tayar1-2/+4
The device heartbeat work is currently initialized at device_heartbeat_schedule() which is called at the end of hl_device_init(). However hl_device_init() can fail at a previous step, and in such a case, a subsequent call to hl_device_fini() will lead to calling cleanup_resources() and accessing this work uninitialized. As there is no real need to re-initialize this work every time it is rescheduled, move this initialization to device_early_init() to be done once and early enough.

2024-06-23accel/habanalabs: revise print on EQ heartbeat failureTomer Tayar1-9/+10
Don't print the "previous EQ index" value in case of a EQ heartbeat failure, because it is incremented along with the EQ CI and therefore redundant. In addition, as the CPU-CP PI is zeroed when it reaches a value that is twice the queue size, add a value of the CI with a similar wrap around, to make it easier to compare the values.
