[PATCHv4 0/6] Driver for new VMD device

Show all headers | View raw

Version 4 after re-working the irq domain hierarchies.

v3 -> v4:

  Patch from Jiang to allow parent-less msi irq domain.

  Separated kernel API dependency exports into their own patch.

  Removed the vmd irq domain hierarchy, and instead use a msi irq
  domain. This pushed all the irq initialization and teardown handling
  into the irq_chip implementation and reduced kernel dependencies.

  Using devm_request_irq instead of an irq flow handler. This moves the
  irq life management to the devres API which simplifies teardown.

  Implemented a smarter method of selecting the VMD vector to share.

  Lots style fixes/updates and additional code comments.

The one review comment I have not fixed is the affinity hint. We are
still developing a way to better handle this, so have left it as a error
returning stub. It's less than optimal, but isn't more harmful than that.

  pci: skip child bus with conflicting resources
  Export msi and irq functions for module use
  x86-pci: allow pci domain specific dma ops
