it works for ZTE modem, but still hung with -usbdevice host:2022:0008

any ideas?

Hi all,
We are investigating if the generic IOMMU API (include/linux/iommu.h)
can be used
for the IOMMU on our arm-based boards. I noticed that msm's IOMMU code
(arch/arm/mach-msm/iommu.c) uses the genric IOMMU API and have a few queries
regarding the supported features. Following are some

That should work. The question is if it's worth the effort. The
current code is there after

Use vmx_set_nmi_mask() instead of open-coding management of
the hardware bit and the software hint (nmi_known_unmasked).
There's a slight change of behaviour when running without
hardware virtual NMI support - we now clear the NMI mask if
NMI delivery faulted in that case as well. This improves

I am not familiar with that device. It may well not be compatible going
through the USB 1.1 controller.
So -usbdevice cleared the "freeze"/"hung" problem the

As Avi recently mentioned, the new standard mechanism for exposing features
is KVM_GET_SUPPORTED_CPUID, not spanning CAPs. For some reason async pf missed
that.
So expose async_pf here.

Commit 1a836445 moved pci.o from a target object to a generic hardware
object, which drops CONFIG_KVM_DEVICE_ASSIGNMENT. This results in
the device assignment kludge to update INTx vectors on interrupt
routing changes never getting called, which means device assignment

Hi,
I deployed KVM on my Gentoo servers for performance testing, but I am now
having high
latency problems with the VirtIO NIC:
diggle7 is the KVM host, diggle6 is another physical host in the same physical
network, and
app211 is a KVM guest running on diggle7.

OK, we'll be getting rid of the "kick on full", so please delete that on
all benchmarks.

Hi all,
While remote debugging a kernel (not written in C and no debugging
symbols) using qemu-kvm with gdb, strange it does not stop at
breakpoint though qemu works well:
Commands:
# qemu-kvm -s -S -hda hd.img &
#gdb
(gdb) target remote localhost:1234
Remote debugging using localhost:1234
