This issue came up when debugging pcpu linked list corruption (patches for that issue to follow). -- Andrew Cooper - Dom0 Kernel Engineer, Citrix XenServer T: +44 (0)1223 225 900, http://www.citrix.com _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel

Hi, on a Nehalem system with VT-d enabled we are seeing strange ACPI-Table contents, especially a corrupted DMAR entry. The hypervisor shows following data on boot: (XEN) ACPI: RSDP 000F80E0, 0024 (r2 PTLTD ) (XEN) ACPI: XSDT BF7C469E, 00D4 (r1 PTLTD XSDT 60000 LTP 0) (XEN) ACPI: FACP BF7C9CC9, 00F4 (r3 FSC TYLERBRG 60000 PTL F4240) (XEN) ACPI: DSDT BF7C4772, 54D3 (r1

...It also uses _write_gate_lower. The IDT entry helpers are required because: * Is it unsafe to attempt a disable/update/re-enable cycle on the NMI or MCE IDT entries. * We need to be able to update NMI handlers without changing the IST entry. As a result, the new behaviour of the kexec_crash path is: nmi_shootdown_cpus() will: * Disable the crashing cpus NMI/MCE interrupt stack tables. Disabling the stack tables removes race conditions which would lead to corrupt exception frames and infinite loops. As this pcpu is never planning to execute a sysret back to a pv vcpu, t...

Hello everyone, this is the fourth version of the patch series that introduces ARMv7 with virtualization extensions support in Xen. The series allows Xen and Dom0 to boot on a Cortex-A15 based Versatile Express simulator. See the following announce email for more informations about what we are trying to achieve, as well as the original git history: See
