Re: NetBSD 6 - Xen 4.2.3 pciback support?

Btw sorry Manuel I missed the reply where you said:

"BTW I'm not sure wht it's trying to access /sys/bus/pci.
patch-libxl_libxl__internal.h changes this to /kern/xen/pci for
NetBSD.

I was just looking at the path and indeed this does not make sense,
there must be somewhere else where this is defined again.

I'm clueless about the /sys/bus/pci/drivers/pciback/slots

In a linux Dom0 (debian) I see all this:
# ls -l /sys/bus/pci/drivers/pciback/
total 0
--w------- 1 root root 4096 Jan 11 17:38 bind
-r-------- 1 root root 4096 Jan 11 17:38 irq_handlers
--w------- 1 root root 4096 Jan 11 17:38 irq_handler_state
lrwxrwxrwx 1 root root    0 Jan 11 17:38 module ->
../../../../module/xen_pciback
--w------- 1 root root 4096 Jan 11 17:38 new_id
--w------- 1 root root 4096 Jan 11 17:38 new_slot
-rw------- 1 root root 4096 Jan 11 17:38 permissive
-rw------- 1 root root 4096 Jan 11 17:38 quirks
--w------- 1 root root 4096 Jan 11 17:38 remove_id
--w------- 1 root root 4096 Jan 11 17:38 remove_slot
-r-------- 1 root root 4096 Jan 11 17:38 slots
--w------- 1 root root 4096 Jan 11 17:38 uevent
--w------- 1 root root 4096 Jan 11 17:38 unbind

Its clearly very different from NetBSD

Thanks
