2023-10-09	accel/habanalabs/gaudi2: add eq health check using irq	farah kassabri	1	-0/+1
	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.

2023-10-09	accel/habanalabs/gaudi2: handle eq health heartbeat check	farah kassabri	1	-1/+13
	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.

	The CPUCP interface is moved to a shared folder outside of accel as a pre-requisite to upstream the NIC drivers that will also include this file. Signed-off-by: David Meriin <dmeriin@habana.ai> Reviewed-by: Oded Gabbay <ogabbay@kernel.org> Signed-off-by: Oded Gabbay <ogabbay@kernel.org>
