It is part of my via-apollo-pro-133t=0D branch [1] which is an extension of bringing the VIA south bridges to the P= C=0D machine [2].

Patch 5 is a preparati= on=0D for that which removes some redundancies which otherwise had to be dealt wi= th=0D during relocation.=0D =0D Patches 7-9 implement toggling and relocation for types TYPE_ISA_FDC,=0D TYPE_ISA_PARALLEL and TYPE_ISA_SERIAL. Patch 10 prepares the pegasos2 machi= ne=0D which would end up with all SuperI/O functions disabled if no -bios argumen= t is=0D given. Patch 11 finally implements the main feature which now relies on=0D firmware to configure the SuperI/O functions accordingly (except for pegaso= s2).=0D =0D v4:=0D * Drop incomplete SuperI/O vmstate handling (Zoltan)=0D =0D v3:=0D * Rework various commit messages (Zoltan)=0D * Drop patch "hw/char/serial: Free struct SerialState from MemoryRegion"=0D (Zoltan)=0D * Generalize wording in migration.rst to include portio_list API (Zoltan)=0D =0D v2:=0D * Improve commit messages (Zoltan)=0D * Split pegasos2 from vt82c686 patch (Zoltan)=0D * Avoid poking into device internals (Zoltan)=0D =0D Testing done:=0D * `make check`=0D * `make check-avocado`=0D * Run MorphOS on pegasos2 with and without pegasos2.rom=0D * Run Linux on amigaone=0D * Run real-world BIOSes on via-apollo-pro-133t branch=0D * Start rescue-yl on fuloong2e=0D =0D [1] https://github.com/shentok/qemu/tree/via-apollo-pro-133t=0D [2] https://github.com/shentok/qemu/tree/pc-via=0D =0D Bernhard Beschow (11):=0D hw/block/fdc-isa: Move portio_list from FDCtrl to FDCtrlISABus=0D hw/block/fdc-sysbus: Move iomem from FDCtrl to FDCtrlSysBus=0D hw/char/parallel: Move portio_list from ParallelState to=0D ISAParallelState=0D exec/ioport: Resolve redundant .base attribute in struct=0D MemoryRegionPortio=0D exec/ioport: Add portio_list_set_address()=0D exec/ioport: Add portio_list_set_enabled()=0D hw/block/fdc-isa: Implement relocation and enabling/disabling for=0D TYPE_ISA_FDC=0D hw/char/serial-isa: Implement relocation and enabling/disabling for=0D TYPE_ISA_SERIAL=0D hw/char/parallel-isa: Implement relocation and enabling/disabling for=0D TYPE_ISA_PARALLEL=0D hw/ppc/pegasos2: Let pegasos2 machine configure SuperI/O functions=0D hw/isa/vt82c686: Implement relocation and toggling of SuperI/O=0D functions=0D =0D docs/devel/migration.rst | 6 ++--=0D hw/block/fdc-internal.h | 4 ---=0D include/exec/ioport.h | 4 ++-=0D include/hw/block/fdc.h | 3 ++=0D include/hw/char/parallel-isa.h | 5 +++=0D include/hw/char/parallel.h | 2 --=0D include/hw/char/serial.h | 2 ++=0D hw/block/fdc-isa.c | 18 +++++++++-=0D hw/block/fdc-sysbus.c | 6 ++--=0D hw/char/parallel-isa.c | 14 ++++++++=0D hw/char/parallel.c | 2 +-=0D hw/char/serial-isa.c | 14 ++++++++=0D hw/isa/vt82c686.c | 66 ++++++++++++++++++++++++++++------=0D hw/ppc/pegasos2.c | 15 ++++++++=0D system/ioport.c | 41 +++++++++++++++++----=0D 15 files changed, 172 insertions(+), 30 deletions(-)=0D =0D -- =0D 2.43.0=0D =0D
