[Xen-devel] [PATCH 0 of 6] xl PCI passthrough updates v3
my current libxl PCI-passthrough patch-queue rebased modulo what has alread
been applied.
Changes since v1:
1. Move pci FLR function in to libxl_pci.c - got it all in now.
2. Properly initialize pci device structs in new code
3. Incorporate suggestions from Stefano wrt. API and putting sysfs paths in
macros.
4. Rename libxl_device_pci_list to libxl_device_pci_list_assigned due to
change in parameters for consistency with the rest of libxl PCI API.
5. Also introduced a patch to centralise parsing of PCI BDF's and allow
omission of the PCI domain as a short-hand for both config files and
hot-plug command parameters. This also fixes an infinite loop in xl create
if there is a parse error in the pci config.
Changes since v2:
1. Use SYS_PCI_DEV macro in libxl_device_pci_reset
2. Fix error in libxl_device_pci_list_assigned() as pointed out by Ian
Campbell
3. Get rid of scan_sys_pcidir() and implement inside
libxl_device_pci_list_assignable() since we're not supporting pcistub
driver now
4. New patch: prevent attempting removal of non-attached device
5. New patch: implement pci attach to explicitly defined virtual PCI slot
6. New patch: corresponding to qemu-dm patch, detect pci insertion errors
which are otherwise undetectable and cause a hang
7. New patch: implement PCI passthrough for multi-function
