Tsirkin" Hi, This patchset is a cleanup of the i8257/i82374 ISA DMA controllers. Global DMA_* functions will be obsoleted and then deleted, and ISA device= s will not be tied anymore to i8257 DMA device implementation. This paves the way to fix support for floppy DMA operations on sparc/spar= c64/MIPS Magnum platforms (which don't use a i8257 DMA controller), and to support multip= le ISA buses on the same machine. Patch 1 cleans up the i82374 DMA controller, by removing device inheritan= ce. Patches 2 to 9 change i8257 to current standards (structures and function= s renaming, QOM) Patches 10 to 18 create and use a IsaDma interface, to separate devices f= rom i8257 device implementation. Patch 19 removes now unused DMA_* functions. Herv=C3=A9 Changes since v1: - added patches 4 and 9 - simplify patch 12, so that it compiles alone (John Snow) - fix warning with clang (John Snow) Herv=C3=A9 Poussineau (19): i82374: device only existed as ISA device, so simplify device i8257: pass ISA bus to DMA_init() function i8257: rename struct dma_cont to I8257State i8257: rename struct dma_regs to I8257Regs i8257: rename functions to start with i8257_ prefix i8257: make the DMA running method per controller i8257: add missing const i8257: QOM'ify i8257: move state definition to new independent header isa: add an ISA DMA interface, and store it within the ISA bus i8257: implement the IsaDma interface magnum: disable floppy DMA for now sparc: disable floppy DMA sparc64: disable floppy DMA fdc: use IsaDma interface instead of global DMA_* functions cs4231a: use IsaDma interface instead of global DMA_* functions gus: use IsaDma interface instead of global DMA_* functions sb16: use IsaDma interface instead of global DMA_* functions dma: remove now useless DMA_* functions hw/audio/cs4231a.c | 23 ++- hw/audio/gus.c | 20 ++- hw/audio/sb16.c | 23 ++- hw/block/fdc.c | 65 +++++--- hw/dma/i82374.c | 58 +++---- hw/dma/i8257.c | 395 ++++++++++++++++++++++++++----------------= ------ hw/i386/pc.c | 2 +- hw/isa/isa-bus.c | 21 +++ hw/mips/mips_fulong2e.c | 2 +- hw/mips/mips_jazz.c | 5 +- hw/mips/mips_malta.c | 2 +- hw/sparc/sun4m.c | 24 +-- hw/sparc64/sun4u.c | 37 ++--- include/hw/isa/i8257.h | 42 +++++ include/hw/isa/isa.h | 51 +++++-- include/qemu/typedefs.h | 1 + 16 files changed, 454 insertions(+), 317 deletions(-) create mode 100644 include/hw/isa/i8257.h --=20 2.1.4
