[Xen-devel] Xen ARM dom0 PCI patches

[Ian Campbell <Ian.Campbell@xxxxxxxxxx>]

Hi Manish,

Do you have some patches which wire up the PCI related physdev
hypercalls (e.g. PHYSDEVOP_pci_device_add) ?

In the context of
http://lists.xenproject.org/archives/html/xen-devel/2014-10/msg03029.html I've 
concluded that the approach in the final patch wrt the interrupts-map property 
is wrong. Instead I would like to use PHYSDEVOP_pci_device_add to map the 
correct IRQ at registration time (i.e. by reading the PCI CFG PIN register, and 
then translating according to the spec).

However that requires the ability to go from a PCI seg+bus+devfn to a DT
node (usually this will be a mapping from seg=>root complex, but not
always). Have you implemented that bit? How did you determine the
correct mapping?

Any chance you could share an initial version of your patches? (Just the
host/dom0 side, no need for the passthrough related bits for this
particular problem)

Ian.
