Hi,
after updating my current base system (unknown from what anymore)
I was restarting one of my development bhyves which has two
passthru (one wifi card and one full pci xhci).
I am now getting:
pci_passthru: unmap_pptdev_mmio failed: No such file or directory
pci_passthru: unmap_pptdev_mmio failed: No such file or directory
pci_passthru: unmap_pptdev_mmio failed: No such file or directory
which is a fairly unhelpful message. Could at least tell the device
if not more...
Anyone any ideas where this is from (or how to fix it)?
So this comes from ppt.c in the kernel ppt_find().
I am a bit buffled given:
[1.001385] ppt0 mem 0xe1320000-0xe132ffff at device 20.0 on pci0
[1.001386] ppt0: attached
[1.001445] ppt1 mem 0xe1000000-0xe10fffff,0xe1100000-0xe1107fff at device 0.0
on pci2
[1.001446] ppt1: attached
% pciconf -l | grep ppt
ppt0@pci0:0:20:0: class=0x0c0330 rev=0x21 hdr=0x00 vendor=0x8086
device=0x9d2f subvendor=0x17aa subdevice=0x5062
ppt1@pci0:3:0:0: class=0x028000 rev=0x00 hdr=0x00 vendor=0x14c3
device=0x0616 subvendor=0x14c3 subdevice=0xe616
% sysctl hw.vmm.ppt
hw.vmm.ppt.devices: 2
The config syas:
pci.0.1.0.device=passthru
pci.0.1.0.bus=0
pci.0.1.0.slot=20
pci.0.1.0.func=0
pci.0.2.0.device=passthru
pci.0.2.0.bus=3
pci.0.2.0.slot=0
pci.0.2.0.func=0
pci.0.10.0.device=virtio-net
pci.0.10.0.backend=tap3
Funny enough not even the network interface is available to netboot upon
start.
I'll keep digging but if someone has a clue to save me some time that would
be appreciated.
Never mind, not ppt_find but the other function; it's a bug in 36b855f189257.
I'll follow-up on the ocmmit.
