2023-10-09accel/habanalabs: register compute device as an accel deviceTomer Tayar
Register the compute device as an accel device, and remove the creation of the habanalabs compute char device. The IOCTLs in this patch are still handled by the current driver handler. Moving to DRM IOCTL handling requires moving the IOCTLs numbers to a specific range, so it will be handled in subsequent patches.

2023-10-09accel/habanalabs: fix wait_for_interrupt abortion flowfarah kassabri
When the driver needs to abort waiters for interrupts, for cases such as critical events that occur and driver need to do hard reset, in such scenario the driver will complete the fence to wake up the waiting thread, and will set the fence error indication. The return value of the completion API will be greater than 0 since it will return the timeout, but as this indicates successful completion, the driver should mark it as aborted.

2023-10-09accel/habanalabs: Allow single timestamp registration request at a timefarah kassabri
Protect against concurrency of user requesting to register a timestamp offset (where the driver fills the timestamp when the command submission has finished executing) to a specific user interrupt ID. The protection is basically to allow only one timestamp registration request to be handled at a time. This is needed because the user can decide to re-use a timestamp offset (register an already registered offset, to a different interrupt ID). This means the request will cause the timestamp node to move from one interrupt list to another interrupt list. In such scenario, without proper protection, we could end up adding the same node twice to the interrupts wait lists.

2023-10-09accel/habanalabs: set device status 'malfunction' while in rmmodKoby Elbaz
hl_device_status() returns the status of an acquired device. If a device is going down (following an rmmod cmd), it should be marked as an unusable/malfunctioning device, and hence should not be acquired. However, since this was not the case so far (i.e., a device going down would inaccurately return 'in reset' status allowing the user to acquire the device) it introduced a bug where as part of a reset flow, the driver could not kill processes that have not run yet, and since those processes aren't blocked from reacquiring a device, we get eventually a new flow of a driver attempting to kill all processes in a list that can't be ever really empty.

If hl_device_cond_reset() is called while a reset is already pending but hasn't started, the reset request will be dropped. If the flags of the new request are more severe, e.g. a hard reset while the pending reset is a compute reset, the eventual reset won't be suitable for the device status.

2023-10-09accel/habanalabs: prevent immediate hard reset due to 2 adjacent H/W eventsTomer Tayar
When a H/W event is received while a user is registered to events, no immediate hard reset will happen, and instead the user will be notified and will have some time to handle it and eventually release the device, after which the reset will be done. If a user, as part of the handling and as part of the cleanup steps towards releasing the device, unregisters from receiving those events, and at that time an adjacent H/W event is received, it will be assumed that the user is not registered to events and thus an immediate hard reset is required. To prevent such an unwanted immediate reset, modify the driver to perform it if the user is not registered to events AND we don't already have a pending reset for a previous H/W event.

2023-04-08accel/habanalabs: sync f/w events interrupt in hard resetTal Cohen
Receiving events from FW, while the device is in hard reset, causes a warning message in Driver log. The message may point to a problem in the Driver or FW. But It also can appear as a result of events that have been sent from FW just before the hard reset. In order to avoid receiving events from FW while the device is in reset and is already in 'disabled' mode, sync the f/w events interrupt right before setting the device to 'disabled'.
