| |
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
