This tag contains the following changes for kernel 5.8:
- Improve MMU cache invalidation code and handle case where the
invalidation doesn't finish in a reasonable time.
- Remove the option to perform soft-reset to GAUDI. Soft-reset is where the
driver only resets the compute and DMA engines of the ASIC. This is not
relevant to GAUDI as we must also reset the NIC ports. And when we reset
the NIC ports, we must also reset other stuff so we prefer to just do
hard-reset (where we reset the entire ASIC except for PCIe).
- Fail the hard-reset procedure in case we still have user processes which
have active file-descriptors on a device. Doing hard-reset in that case
can result in a kernel panic because of gen_pool checks
- Don't initialize the default wait callback of dma_buf with the default
wait function as that's the default...
