[PATCH 0/3] s390x/pci: rpcit fixes and enhancements

Posted by Matthew Rosato 1 year, 6 months ago

The following series fixes an issue with guest RPCIT processing discovered
during development of [1] as well as proposes a few additional optimizations
to the current RPCIT codepath.

[1] https://lore.kernel.org/linux-s390/20221019144435.369902-1-schnelle@linux.ibm.com/

Matthew Rosato (3):
  s390x/pci: RPCIT second pass when mappings exhausted
  s390x/pci: coalesce unmap operations
  s390x/pci: shrink DMA aperture to be bound by vfio DMA limit

Thanks, I've queued patch 2 and 3 now to my s390x-next branch, too:
