SVN rev 188032 on 2009-02-02 22:04:40Z by jhb
- Add a new ioctl to /dev/pci to fetch details on an individual BAR of a
device. The details include the current value of the BAR (including all
the flag bits and the current base address), its length, and whether or not
it is enabled. Since this operation is not invasive, non-root users are
allowed to use it (unlike manual config register access which requires
root). The intention is that userland apps (such as Xorg) will use this
interface rather than dangerously frobbing the BARs from userland to
obtain this information.
- Add a new sub-mode to the 'list' mode of pciconf. The -b flag when used
with -l will now list all the active BARs for each device.
