habanalabs: send device active message to f/w

2022-09-19T12:08:37Z

As part of the RAS that is done by the f/w, we should send a message to the f/w when a user either acquires or releases the device. Signed-off-by: farah kassabri Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

habanalabs: perform context switch flow only if needed

2022-09-18T10:29:53Z

Except Goya, none of our ASICs require context switch flow, hence we enable this flow only where it is needed. Signed-off-by: Ofir Bitton Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

habanalabs: unify hwmon resources clean up

2022-09-18T10:29:51Z

Since hwmon fini code is common for all asics, unified it to common function. Signed-off-by: Dani Liberman Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

habanalabs: remove all kdma locks

2022-09-18T10:29:50Z

We don't use KDMA concurrently in the driver. The only use is through debugfs and we don't protect concurrent access through it. Reported-by: Dan Carpenter Signed-off-by: Oded Gabbay

habanalabs: rename non_hard_reset to compute_reset

2022-09-18T10:29:49Z

In order to be more explicit we should use the term compute_reset for describing the reset in which only the compute engines gets reset. Signed-off-by: Ofir Bitton Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

habanalabs: removed seq_file parameter from is_idle asic functions

2022-09-18T10:29:49Z

Change is_idle functions so it would be more usable outside debugfs. Do this by replacing seq_file parameter with regular string. Signed-off-by: Dani Liberman Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

habanalabs: move h/w dirty message to debug

2022-07-12T06:09:31Z

H/W being dirty during initialization is completely expected in case f/w tools are used before loading the driver. As it is not an error, and as it doesn't give any meaningful information to the user, no point of printing it. Signed-off-by: Oded Gabbay

habanalabs: rename soft reset to compute reset

2022-07-12T06:09:31Z

Doing compute reset can be the traditional inference soft reset that is supported only in Goya. Or it can be the new reset upon device release, which is supported in Gaudi2 and above. Therefore, wherever suitable, use the terminology of compute reset instead of soft reset. Signed-off-by: Oded Gabbay

habanalabs: add a value field to hl_fw_send_pci_access_msg()

2022-07-12T06:09:30Z

For gaudi2 we need to send a value to F/W as part of the PCI_ACCESS packet. As a preparation, modify hl_fw_send_pci_access_msg() to have a 'value' field. Signed-off-by: Tomer Tayar Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

habanalabs: wait for preboot ready after hard reset

2022-07-12T06:09:28Z

Currently we are not waiting for preboot ready after hard reset. This leads to a race in which COMMs protocol begins but will get no response from the f/w. Signed-off-by: Ohad Sharabi Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay
