This cover letter is missing a pointer to the Linux kernel patches that enable the pvpanic driver to use the MMIO interface. If that hasn't been done yet, then how has this series been tested? Thanks, drew
The first patches are simple cleanups: - patch 1 move the pvpanic device with the 'ocmmon objects' so we compile it once for the x86/arm/aarch64 archs, - patch 2 simply renames ISA fields/definitions to generic ones. Then instead of add/use the MMIO pvpanic device in the virt machine in an unique patch, I split it in two distinct patches: - patch 3 uses Peng Hao's work, but add the MMIO interface to the existing device (no logical change). - patch 4 is Peng Hao's work in the virt machine (no logical change). - patch 5 add pvpanic device in acpi table in virt machine v2 from Peng Hao is: https://lists.gnu.org/archive/html/qemu-devel/2018-10/msg03433.html v3 --> v4 patch 1,2 no modification. patch 3, add TYPE_PANIC_MMIO for distinguishing different bus device, virt + isa_pvpanic will abnormally terminate virtual machine. patch 4, "pvpanic,mmio" --> "qemu,pvpanic-mmio". patch 5, newly added. v4 --> v5 patch 1,2 no modification. patch 3 delete PvpanicCommonState structure. patch 4 VIRT_PVPANIC_MMIO --> VIRT_PVPANIC correct VIRT_PVPANIC's overlap start address patch 5 no modification.
