Hi, I''m trying to port AMD VGA passthru patch to the latest XEN and vanila kernel and I got SIGSEGV in static void ati_hw_out(uint16_t hport, uint32_t data) { ioperm(gfx_info.host_pio_base, gfx_info.pio_size, 1); asm volatile ("out %1, %0"::"Nd"(hport),"a"(data)); ioperm(gfx_info.host_pio_base, gfx_info.pio_size, 0); } I tried old 2.6.32

Hi, everyone! I am working on xen-4.2.0 with spice remote connect. My host is Fedora 14 and guest is win7. I have installed spice package and now I can connect to guest by spice client. For better graphics experience, I want to try the VGA passthrough. With spice tool, I have to create a VM by xl command, and now I am wondering if it supports VGA passghrouth? If so, how should I test it ?

This patch series makes it possible to compile out the userspace IO system calls, iopl and ioperm. The first patch does some 32/64 unification in copy_thread to make subsequent changes easier. The second patch simplifies the complex calculation of the TSS segment limit, which also makes it easier to change in the last patch. Patches 3-9 introduce helpers to make it easier to compile out IO.

Three of the patches could be squashed in one, but it makes more sense to review them as three. These patches fix the case of an PVHVM guest not being able to resume propely b/c of hitting: 142 BUG_ON(info->type != IRQT_UNBOUND && info->type != type); (in events.c) and also adds a WARN to catch situations like these. The reason for this is that the Xen python toolstack

These two patches provide the neccessary infrastructure changes for the processor-passthru driver [www.spinics.net/lists/linux-acpi/msg34655.html] to properly function. The first one is quite easy - we just modprobe the processor-passthru driver. The second allows it to work under AMD machines by exposing the PM RDMSR to dom0. It has been tested with 2.6.32 kernel as well to make sure it does

The attached patches allow the pciback module to perform a reset whenever a PCI device is: - attached to the pciback module, as so: echo "0000:01.07.0" > /sys/bus/pci/devices/pciback/bind - detached from the pciback module, as so: echo "0000:01.07.0" > /sys/bus/pci/devices/pciback/unbind - and when the guest is done with (internally when the guest is not using

I am working on some other bugs and perf issues - and while working I noticed that both sparse and Coverity have reported some issues with Xen drivers. Please see attached various bug-fixes that I am proposing for 3.6.

Hey Stefano, I setup a cross ARM build system so that the generic changes won''t cause build issues on ARM (and actually caught a bug with fallback.o being enabled there - I''ve a fix for that). But more interestingly the build system I do also makes a variations of config entries. So there is the allmodules, allyes, allyes, but all Xen drivers are modules, etc. I found out that

I am proposing these two patches for 3.2. They allow the backend to process the REQ_FUA request as well. Previous to these patches it only did REQ_FLUSH. There is also a bug-fix for the logic of how barrier/flushes were handled. The patches are based on a branch which also has ''feature-discard'' patches, so they won''t apply nativly on top of 3.1-rc5. Please review and

First, maintainer''s addresses (Ryan Wilson <hap9@epoch.ncsc.mil>, Chris Bookholt <hap10@epoch.ncsc.mil>) are wrong (users unknown to remote mailsystem), so posting to you: PCI bus format strings are wrong. "%04x:%02x:%02x.%d" should be used instead of "%04x:%02x:%02x.%1x" (in many places of linux+v3.2.1/drivers/xen/xen-pciback/pci_stub.c) --

Are you expecting improvement after  09/15/2009 new-swiotlb commits ? 4097,6144, "No_dom0_mem_specified" don''t look to me to have any. Boris.   _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hello, The following patches are a solution to a problem we have encountered when using the Xen hypervisor: - Need Pxx/Cxx states to save on power consumption when using Xen (we do want those datacenters to consume less power!), - Also need to figure out the Turbo mode so that the scheduler can properly boost a core for CPU bound guests. In essence the Xen hypervisor requires that
