>Synopsis: lspci broken and PCI USB hub not recognized on sparc64
>Category: sparc64
>Environment:
System : OpenBSD 5.5
Details : OpenBSD 5.5-beta (GENERIC) #128: Wed Jan 22 06:50:22 MST
2014
[email protected]:/usr/src/sys/arch/sparc64/compile/GENERIC
Architecture: OpenBSD.sparc64
Machine : sparc64
>Description:
My system is a Sun Ultra 5, that I received with three open PCI slots.
I inserted a generic 5-port USB 2.0 PCI card
into one of the slots, but it was not detected in dmesg or usbdevs, as
you can see below. I installed pciutils and
usbutils from packages, to see if the controller was at least
recognized by the kernel. lsusb returns no output.
Running lspci did not work as expected as an unprivileged user or as
root. As an unprivileged user I got this error:
pcilib: Cannot open /dev/pci
lspci: Cannot find any working access method.
Running lspci as root, I received this different error:
lspci: obsd_read: ioctl(PCIOCREAD) failed
On my system /dev/pci is a symlink to /dev/pci0, which is mode 700 - I
suspect the unprivileged user error was basically
a permissions error on the device node. The root error is more
concerning, since according to pci(4) that should always
work as root when PCI devices are present.
>How-To-Repeat:
Plug a generic USB 2.0 PCI card into a Sun Ultra 5 and run lspci.
>Fix:
unknown, possibly change kernel build to include different drivers, and
change kernel data structures used in lspci
