2011-09-25ppc_prep: fix pci config space initializationAvi Kivity
Use data_mem for the data mmio region, not conf_mem. Signed-off-by: Avi Kivity <avi@redhat.com>
2011-09-25fdc: Convert isabus_fdc_init1 to MemoryRegionRichard Henderson
This requires some amount of hoop-jumping, so that we don't inadvertently claim port 0x3f6, which is used by ISA IDE. The sysbus initialization path is as yet unconverted. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-09-25serial: Convert serial_isa_initfn to MemoryRegionRichard Henderson
The serial_mm_init path is as yet unconverted. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-09-25pckbd: Convert to MemoryRegionRichard Henderson
Slightly non-obvious with mips_jazz passing in the region structure to populate. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-09-25i8259: Convert to MemoryRegionRichard Henderson
The only non-obvious part is pic_poll_read which used "addr1 >> 7" to detect whether one referred to either the master or slave PIC. Instead, test this directly. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-09-25ppc_prep: initialize i8259 after the ISA busAvi Kivity
Succeeding i8259 conversion to ISA requires this. Signed-off-by: Avi Kivity <avi@redhat.com>
2011-09-25mips_r4k: initialize i8259 after the ISA busAvi Kivity

2011-09-25mips_jazz: initialize i8259 after the ISA busAvi Kivity
Succeeding i8259 conversion to ISA requires this. Signed-off-by: Avi Kivity <avi@redhat.com>
2011-09-25mips_malta: move i8259 initialization after piix4 initializationAvi Kivity
i8259 is an ISA device (or at least, depends on the ISA infrastructure to register its ioport); and the ISA bus is supplied by piix4. Later patches make this dependency explicit. Use qemu_irq_proxy() to stop the cycle by adding an extra layer of indirection. Signed-off-by: Avi Kivity <avi@redhat.com>

2011-09-25pc: Re-order pc_init1 to initialize the ISA bus before ISA devicesRichard Henderson
In particular, the i8259 was being initialized before the ISA bus, leading to a crash. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-09-25isa: add isa_register_ioport()Richard Henderson
To replace isa_init_ioport and isa_init_ioport_range as the ISA devices are converted to the memory api. [avi: use memory_region_size()] Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-09-25isa: Pass i/o address space to isa_bus_newRichard Henderson
Not used yet, but at least we're provided with the correct region. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-09-25pci: add pci_address_space_io()Richard Henderson
Returns the I/O address space. Useful for implementing PCI-ISA bridge devices. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Avi Kivity <avi@redhat.com>

2011-09-23irq: introduce qemu_irq_proxy()Avi Kivity
In some cases we have a circular dependency involving irqs - the irq controller depends on a bus, which in turn depends on the irq controller. Add qemu_irq_proxy() which acts as a passthrough, except that the target irq may be set later on.

2011-09-23virtio: Use global memory barrier macrosDavid Gibson
The virtio code uses wmb() macros in several places, as required by the SMP-aware virtio protocol. However the wmb() macro is locally defined to be a compiler barrier only. This is probably sufficient on x86 due to its strong storage ordering model, but it certainly isn't on other platforms, such as ppc. In any case, qemu already has some globally defined memory barrier macros in qemu-barrier.h. This patch, therefore converts virtio.c to use those barrier macros. The macros in qemu-barrier.h are also wrong (or at least, safe for x86 only) but this way at least there's only one place to fix them.

2011-09-23pci-devfn: check that device/slot number is within rangeDonald Dutile
Need to check that guest slot/device number is not > 31 or walk off the devfn table when checking if a devfn is available or not in a guest. before this fix, passing in an addr=abc or addr=34, can crash qemu, sometimes fail gracefully if data past end of devfn table fails the availability test. with this fix, get clean error: Property 'pci-assign.addr' doesn't take value '34' also tested when no addr= param passed for guest (pcicfg) address, and that worked as well.

2011-09-23vga: Unbreak ISA supportJan Kiszka
We need to initialize legacy_address_space during ISA VGA setup so that the chain-4 alias can be registered properly. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-09-23pc: Unbreak ROM mapping for ISA machineJan Kiszka
This is based on the original fix by Hervé Poussineau: pc_memory_init actually takes a memory region for mapping BIOS and extension ROMs. That equals the PCI memory region if PCI is available, but must be system memory in the ISA case.

2011-09-23e1000: Don't set the Capabilities List bitdann frazier
[Originally sent to qemu-kvm list, but I was redirected here] The Capabilities Pointer is NULL, so this bit shouldn't be set. The state of this bit doesn't appear to change any behavior on Linux/Windows versions we've tested, but it does cause Windows' PCI/PCI Express Compliance Test to balk. I happen to have a physical 82540EM controller, and it also sets the Capabilities Bit, but it actually has items on the capabilities list to go with it :) Signed-off-by: dann frazier <dann.frazier@canonical.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-09-23hw/omap1: Wire up GPIO clockPeter Maydell
Wire up the OMAP1 GPIO clock -- this fixes a hw_error() on startup with OMAP1 based machines (sx1, cheetah). Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-09-23omap_intc: QdevifyPeter Maydell
Convert the omap_intc devices to qdev. This includes adding a 'revision' property which will be needed for omap3. The bulk of this patch is the replacement of "s->irq[x][y]" with "qdev_get_gpio_in(s->ih[x], y)" now that the interrupt controller exposes its input lines as qdev gpio inputs. The devices are named "omap-intc" and "omap2-intc", following the filename and the OMAP2/3 hardware names, although some internal functions are still named "omap_inth_*".

2011-09-21ahci: add port I/O index-data pairDaniel Verkamp
Implement an I/O space index-data register pair as defined by the AHCI spec, including the corresponding SATA PCI capability and BAR. This allows real-mode code to access the AHCI registers; real-mode code cannot address the memory-mapped register space because it is beyond the first megabyte.
