accel/habanalabs: separate nonce from max_size in cpucp_packet struct

2024-06-23T06:53:04+00:00

In struct cpucp_packet both nonce and data_max_size members are in an union overlapping each other. This is a problem as they both are used in attestation and info_signed packets. The solution here is to move the nonce member to a different union under the same structure. Signed-off-by: Dani Liberman Reviewed-by: Ofir Bitton Signed-off-by: Ofir Bitton

accel/habanalabs/gaudi2: add eq health check using irq

2023-10-09T09:37:21+00:00

This is the second patch for applying the eq health check mechanism which will add support for the interrupt flow for gaudi2 asic. More info about the interrupt mechanism: set a dedicated msix for the eq error interrupt, and add interrupt handler for it. when FW detects some issue with EQ like EQ_FULL, it'll raise that interrupt and driver should reset the device. Driver will inform the FW which msix index to use through the already existing handshake mechanism which will send msix info message to fw.

accel/habanalabs/gaudi2: handle eq health heartbeat check

2023-10-09T09:37:21+00:00

Add mechanism for fw eq health check. this will be done using two flows: using the heartbeat mechanism and raising a dedicated interrupt to indicate an eq failure like EQ full. This patch will add implementation for the eq heartbeat for gaudi2 asic. More info about the heartbeat mechanism: Expand the heartbeat mechanism to monitor a new event that will be sent from FW upon receiving heartbeat message. that way driver can know that the eq is working or not.
