Both these patches are on my pci/sparc branch and appeared in the
Feb 19 linux-next tree.
Any testing and feedback (especially on the second patch, which should
change /proc/iomem) would be great.
They're headed for v4.17 unless I hear about issues.
It would be useful to hear about what's still broken so I can try to
pull in the other patches.
Hi Bjorn,
I tested these two patches on an M7 machine. With these two patches, one
of the PCI devices was able to claim BAR 0 which it fails to without
these patches. This device happens to be a NIC, so with these two
patches, the NIC finally works on my test machine. I have attached log
showing all the failures to claim a BAR. First file is from 4.16-rc2
while the second one is from 4.16-rc2+these two patches. There still are
a number of failures to claim BAR even with these two patches.
I am also attaching /proc/iomem for the 4.16-rc2 kernel and 4.16-rc2
with these two patches.
