[PATCH v3 0/4] vpci: allow 32-bit BAR writes with memory decoding enabled

Posted by Stewart Hildebrand 1 week, 3 days ago

Pipeline: https://gitlab.com/xen-project/people/stewarthildebrand/xen/-/pipelines/2404206419

v2->v3:
* add ("vpci: Use pervcpu ranges for BAR mapping")
* rework with fixed array of map/unmap slots

v2: https://lore.kernel.org/xen-devel/20250723163744.13095-1-stewart.hildebrand@amd.com/T/#t

v1->v2:
* new approach with queued p2m operations

RFC->v1:
* rework BAR mapping machinery to support unmap-then-map operation

Mykyta Poturai (1):
  vpci: Use pervcpu ranges for BAR mapping

Stewart Hildebrand (3):
  vpci: allow queueing of mapping operations
  vpci: allow BAR map/unmap without affecting memory decoding bit
  vpci: allow 32-bit BAR writes with memory decoding enabled
