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. v5 --> v6 add document. v6 --> v7 patch 5 modify device name from "PANC" to "PEVT". patch 6 modify document description. v7 --> v8 add configure interface for pvpanic-mmio the kernel part of the series: https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git/log/?h=char-misc-testing misc/pvpanic: remove a redundant comma misc/pvpanic: convert to SPDX license tags misc/pvpanic: change header file sort style misc/pvpanic: remove unnecessary header file misc/pvpanic : break dependency on ACPI misc/pvpanic : grouping ACPI related stuff misc/pvpanic: add support to get pvpanic device info FDT dt-bindings: misc/pvpanic: add document for pvpanic-mmio misc/pvpanic: add MMIO support misc/pvpanic: simplify the code using acpi_dev_resource_io pvpanic: move pvpanic to misc as common driver Philippe Mathieu-Daudé (2): hw/misc/pvpanic: Build the pvpanic device in $(common-obj) hw/misc/pvpanic: Cosmetic renaming Peng Hao (8): hw/misc/pvpanic: Add the MMIO interface hw/misc/pvpanic: moving structure definition to header file hw/arm/virt: Use the pvpanic device hw/arm/virt: add pvpanic device in virt acpi table hw/misc/pvpanic: add configure query interface hw/misc/pvpanic: preparing for adding configure interface hw/misc/pvpanic: realize the configure interface pvpanic : update pvpanic document default-configs/arm-softmmu.mak | 1 + docs/specs/pvpanic.txt | 18 +++++++++-- hw/arm/sysbus-fdt.c | 2 ++ hw/arm/virt-acpi-build.c | 18 +++++++++++ hw/arm/virt.c | 22 +++++++++++++ hw/misc/Makefile.objs | 2 +- hw/misc/pvpanic.c | 68 ++++++++++++++++++++++++++++------------- include/hw/arm/virt.h | 1 + include/hw/misc/pvpanic.h | 34 +++++++++++++++++++++ 9 files changed, 140 insertions(+), 26 deletions(-)
