habanalabs: add an option to control watchdog timeout via debugfs

2022-11-23T14:13:43+00:00

Add an option to control the timeout value for the driver's watchdog of the reset process. The timeout represents the amount of the user has to close his process once he gets a device reset notification from the driver. Signed-off-by: Tomer Tayar Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

habanalabs: expose only valid debugfs nodes

2022-07-12T06:09:31+00:00

In case security is enabled on the device, some debugfs nodes will fail. Hence, we do not expose them. Signed-off-by: Ofir Bitton Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

habanalabs: add gaudi2 asic-specific code

2022-07-12T06:09:27+00:00

Add the ASIC-specific code for Gaudi2. Supply (almost) all of the function callbacks that the driver's common code need to initialize, finalize and submit workloads to the Gaudi2 ASIC. It also contains the code to initialize the F/W of the Gaudi2 ASIC and to receive events from the F/W. It contains new debugfs entry to dump razwi events. razwi is a case where the device's engines create a transaction that reaches an invalid destination. Signed-off-by: Oded Gabbay

habanalabs/gaudi: use memory_scrub_val from debugfs

habanalabs: add device memory scrub ability through debugfs

2022-05-22T19:01:20+00:00

Add the ability to scrub the device memory with a given value. Add file 'dram_mem_scrub_val' to set the value and a file 'dram_mem_scrub' to scrub the dram. This is very important to help during automated tests, when you want the CI system to randomize the memory before training certain DL topologies.
