Following patches aim to change ISA bus to a first-citizen class in Qemu. They add ISA bus ops (like for scsi and usb buses), and use them to remove the infamous isa_mem_base variable, which can't be changed after startup.
Last two patches convert two ISA bridges to the new API. ISA bridges used in MIPS/Malta and MIPS/fulong2e are not converted (yet). Once all callers are converted, most of the work will be done to support architectures with multiple ISA buses Hervé Poussineau (6): isa: rename isa_bus_new to isa_bus_bridge_init isa: rework ISA bus internals, and add ISA bus ops structure isa: add isa_address_space() method vga: use isa_address_space() method isa: improve bus implementation of PIIX3 bridge isa: improve bus implementation of ebus bridge hw/cirrus_vga.c | 4 +- hw/isa-bus.c | 86 ++++++++++++++++++++++++++++++++++++++++++++++-------- hw/isa.h | 19 +++++++++++- hw/mips_jazz.c | 2 +- hw/mips_r4k.c | 2 +- hw/pc_piix.c | 4 +- hw/piix4.c | 2 +- hw/piix_pci.c | 23 ++++++++++++++- hw/ppc_prep.c | 2 +- hw/sun4u.c | 39 ++++++++++++++++++++---- hw/vga-isa.c | 4 +- hw/vga.c | 4 +- hw/vt82c686.c | 2 +- 13 files changed, 158 insertions(+), 35 deletions(-) -- 1.7.5.4
