Hello. I'm running Centos 4.3 with KDE from CentOS. There're some "unsupported" packages, like kernel 2.6.9-34.108.plus.c4smp, Picasa and Google Earth. Picasa and Google Earth had never showed critical problems (before), although they're beta versions. Today, I started Picasa and Google Earth at the same time, and the X became a black screen, like it was killed and was just

One could even debate whether reserved bit faults are always fatal (and should never be propagated to the guest)...

Hi, Quite a while ago there were a few patches for adding MTRR support to the Xen kernel, and yes, I know they''ve been NAK from the mainline kernel. I''m wondering if they still exist on some branches of some repo that I could possibly get them from? I found a couple of patch series posted onto the mailing list before but it''s not cleared what version or what tree

When submitting the patch that became 23101:dd386a4b6595 I forgot that I actually intended to remove the pointless IRQ disabling and restoring (and the then pointless comment). Pointless because the code, other than its pre-23013:65d26504e843 original, now runs before interrupts get enabled for the first time. Signed-off-by: Jan Beulich <jbeulich@novell.com> ---

With pretty trivial user mode programs being able to crash the kernel due to the ref counter widths in Xen being more narrow than in Linux, I started an attempt to put together a kernel side fix. While addressing the plain hypercalls is pretty strait forward, dealing with multicalls (both when using them for lazy mmu mode batching and when explicitly using them in e.g. netback - the backends are

I recently realized that the original way of dealing with the DebugCtl MSR on VMX failed to make use of the dedicated guest VMCS field. This is being fixed with this patch. What is puzzling me to a certain degree is that while there is a guest VMCS field for this MSR, there''s no equivalent host load field, but there''s also no indication that the MSR would be cleared during a

Hello, The email (thread) below from xen-devel mailinglist indicates the changesets that should fix the bug that causes the lenny 2.6.26 xen kernel to crash on newer xen hypervisors. The workaround for this bug has been to use pci=nomsi on the dom0 kernel cmdline, but it would be better to apply the actual fix to the xen kernel in lenny.

When operating on an unpinned pagetable (ie, one under construction or destruction), it isn''t necessary to use a hypercall to update a pud/pmd entry. Jan Beulich observed that a similar optimisation avoided many thousands of hypercalls while doing a kernel build. One tricky part is that early in the kernel boot there''s no page structure, so we can''t check to see if the

- avoid leaking stuff in acpi_processor_remove() - remove a pointless change to native code in acpi_processor_hotplug() (struct acpi_processor''s id field is unsigned) - don''t set up processor_extcntl_ops when nothing controlled by Xen (thus processor_cntl_external() will always return false, allowing ACPI code to retain native behavior) As usual, written and tested on

In order to be meaningful and usable together with other measuring methods, their use in my opinion should impose as little overhead as possible. With that, I wonder why per-cpu counters use atomic operations.

This introduces - a (generic) config setting to turn on compatibility mode support - support to load a Dom0 32-bit ELF image on 64-bit - a compatibility guest mode GDT (requires moving the ring 0 selectors to different GDT slots), and the respective selector handling changes - some initial code path changes to address the needs of a compatibility mode guest Signed-off-by: Jan Beulich

Prior to c/s 23811:f1349a968a5a LSR_THRE was checked only once, while there it got promoted into the surrounding loop''s condition. Since that bit may not clear for an extended period of time (i.e. when no new output is generated), it must not be used in this way indefinitely.
