With this patch series I'm trying to address several issues with kexec on pvhvm: - shared_info issue (1st patch, just sending Olaf's work with Konrad's fix) - create specific pvhvm shutdown handler for kexec (2nd patch) - GSI PIRQ issue (3rd patch, I'm pretty confident that it does the right thing) - MSI PIRQ issue (4th patch, and I'm not sure it doesn't break anything -> RFC) This patch series can be tested on single vCPU guest. We still have SMP issues with pvhvm guests and kexec which require additional fixes. Olaf Hering (1): xen PVonHVM: use E820_Reserved area for shared_info Vitaly Kuznetsov (3): xen/pvhvm: Introduce xen_pvhvm_kexec_shutdown() xen/pvhvm: Unmap all PIRQs on startup and shutdown xen/pvhvm: Make MSI IRQs work after kexec arch/x86/pci/xen.c | 3 +- arch/x86/xen/enlighten.c | 83 +++++++++++++++++++++++++++++++--------- arch/x86/xen/smp.c | 10 +++++ arch/x86/xen/smp.h | 1 + arch/x86/xen/suspend.c | 2 +- arch/x86/xen/xen-ops.h | 2 +- drivers/xen/events/events_base.c | 76 ++++++++++++++++++++++++++++++++++++ include/xen/events.h | 3 ++ 8 files changed, 158 insertions(+), 22 deletions(-) -- 1.9.3 _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
