[Xen-devel] xen-swiotlb: WARNING: at kernel/smp.c:421 smp_call_function_
Hi Konrad,
Finally found the time to test the xen-swiotlb again (together with usb3/xhci
isoc pathes)
I began with your tree:
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git
devel/merge.2.6.35-rc3
and after that i merged in a tree for the xhci part that is based on 2.6.35-rc4:
git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci.git amd-isoc
That all went without a problem, booting the resulting kernel in a PV domU
gives the warnings below, i hope these can be addressed before the next merge
window and xen-swiotlb will make it in !
Despite the 2 warnings, the usb devices i passed through seem to work ok.
