[PATCH 0/3] vfio/igd: VFIOConfigMirrorQuirk for igd mirrored registers

Posted by Tomita Moeko 11 months, 3 weeks ago

In commit 1a2623b5c9e7 ("vfio/igd: add macro for declaring mirrored
registers"), I introduced a macro to handle mirrored registers in igd
bar0. However, using the existing VFIOConfigMirrorQuirk should be a
better approach I think after going through the vfio code.

This patch set introduces a new header file, pci-quirks.h, to hold
generic quirk declarations, and extends VFIOConfigMirrorQuirk to
support offsets in PCI config space. This eliminates the need for
the previously introduced macro.

Happy new year :)

  vfio/pci: declare generic quirks in a new header file
  vfio/pci: introduce config_offset field in VFIOConfigMirrorQuirk
  vfio/igd: use VFIOConfigMirrorQuirk for mirrored registers
