Xen hypervisor failed to startup when booting CPUs
...I run into a problem when enabling Xen in next generation server platforms with Xen c/s is 21380. Xen reported "CPU Not responding" when booting up 32 CPUs( 2 sockets with 8 cores/16threads total). The log files belonging showed something wrong with APCI. So I added x2apic=0 in the xen grub line, but the symptom remained. However, Native RHEL5.5 can normally started in this platforms. Does anyone meet this problem and know how to solve it or give some hints? Thanks very much! Btw, I also tried the latest xen (version 4.1 rc5). Hy...

[PATCH]x86:x2apic: Disable x2apic on x86-32 permanently
x86:x2apic: Disable x2apic on x86-32 permanently x2apic initialization on x86_32 uses vcpu pointer before it is initialized. As x2apic is unlikely to be used on x86_32, this patch disables x2apic permanently on x86_32. It also asserts the sanity of vcpu pointer before dereference to prevent further misuse....

[PATCH 3/3] x2APIC: improve enabling logic
This patch masks PIC and IOAPIC RTE''s before x2APIC enabling, unmask and restore them after x2APIC enabling. It also really enables interrupt remapping before x2APIC enabling instead of just checking interrupt remapping setting. This patch also handles all x2APIC configuration including BIOS settings and command line settings. Especially, it handle...

Reboots and Panics(4.1.2/4.2-unstable)
...is library error http://www.gossamer-threads.com/lists/xen/devel/234300 However, after correcting the library error, I was able to complete the unstable build. In both cases, it either stops with a panic/blank screen, or just reboots. Here are some other notes: 1) If x2apic is enabled on the motherboard, it almost immediately reboots with any of the configurations above 2) The boot gets to here: (XEN) HVM: VMX enabled (XEN) HVM: Hardware Assisted Paging detected. Then goes to a "(XEN)Failed to bring up CPU x(error -5)" and this is where it hangs with th...

[PATCH] x86/ACPI/x2APIC: guard against out of range ACPI or APIC IDs
Other than for the legacy APIC, the x2APIC MADT entries have valid ranges possibly extending beyond what our internal arrays can handle, and hence we need to guard ourselves against corrupting memory here.

http://www.intel.com/content/www/us/en/chipsets/5520-and-5500-chipset-ioh-specification-update.html Stepping B-3 has two errata (#47 and #53) related to Interrupt remapping, to which the workaround is for the BIOS to completely disable interrupt remapping. These errata are fixed in stepping C-2. Unfortunately this chipset is very common and many BIOSes are not

[PATCH] VT-d: make remap_entry_to_msi_msg() return consistent message
During debugging of another problem I found that in x2APIC mode, the destination field of the low address value wasn''t passed back correctly. While this is benign in most cases (as the value isn''t being used anywhere), it can be confusing (and misguiding) when printing the value read or when comparing it to the one previously passed into...

[PATCH v4 2/2] Xen: Fix VMCS setting for x2APIC mode guest while enabling APICV
The "APIC-register virtualization" and "virtual-interrupt deliver" VM-execution control has no effect on the behavior of RDMSR/WRMSR if the "virtualize x2APIC mode" VM-execution control is 0. When guest uses x2APIC mode, we should enable "virtualize x2APIC mode" for APICV first.

The last one certainly isn't, and the first two shouldn't (albeit the non-Xen kernel is running in x2APIC mode). That difference is likely because the Xen and...
