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. -- Sander info: Xen version: xen-4.0-testing-pre4 (changeset: 21263:57859775f88f) Dom0 kernel: 2.6.32.16 pvops (commit 006bfe8f594370f36f09d8e8ab13692d34e88533) Attached: - xm dmesg (the part where the domU gets created - dmesg of the domU - lspci -vvvknn of the domU [ 1.471104] ------------[ cut here ]------------ [ 1.471120] WARNING: at kernel/smp.c:421 smp_call_function_many+0x66/0x1a1() [ 1.471126] Modules linked in: thermal_sys [last unloaded: scsi_wait_scan] [ 1.471135] Pid: 153, comm: khubd Not tainted 2.6.35-rc4+konrad+xhci-isoc+ #2 [ 1.471140] Call Trace: [ 1.471147] [<ffffffff81063987>] ?
