The basic high level interface here seems fine, which is bascially a way for a driver to grab a bunch of platform-msi interrupts for its own use > Since I don't have access to any of the platform-msi devices, it is hard for > me to test this code for other drivers expect idxd for now. > Once I submit the next round of patches, after addressing all the comments, > would it be possible for you to test this code for any of your devices?
