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>

2011-09-23irq: 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.

2011-09-23pc: 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>

2011-09-21ahci: 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.

2011-09-20scsi: fix sign extension problemsPaolo Bonzini
When assigning a 32-bit value to cmd->xfer (which is 64-bits) it can be erroneously sign extended because the intermediate 32-bit computation is signed.

2011-09-20AHCI Port Interrupt Enable register cleaning on soft resetAlexander Motin
I've found that FreeBSD AHCI driver doesn't work with AHCI hardware emulation of QEMU 0.15.0. I believe the problem is on QEMU's side. As I see, it clears port's Interrupt Enable register each time when reset of any level happens. Is is reasonable for the global controller reset. It is probably not good, but acceptable for FreeBSD driver for the port hard reset. But it is IMO wrong for the device soft reset. None of real hardware I know behaves that way.

2011-09-20scsi-disk: lazily allocate bounce bufferPaolo Bonzini

2011-09-19pci: implement bridge filteringMichael S. Tsirkin
Support bridge filtering on top of the memory API as suggested by Avi Kivity: Create a memory region for the bridge's address space. This region is not directly added to system_memory or its descendants. Devices under the bridge see this region as its pci_address_space(). The region is as large as the entire address space - it does not take into account any windows. For each of the three windows (pref, non-pref, vga), create an alias with the appropriate start and size. Map the alias into the bridge's parent's pci_address_space(), as subregions. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2011-09-19pci_bridge: use parent bus's address spaceWen Congyang
The switch to the new memory API caused the following problem: The pci device may call pci_register_bar() to use PCI bus's address space. But we don't init PCI bus's address space if it is not bus 0. A crash was reported: http://lists.gnu.org/archive/html/qemu-devel/2011-08/msg02243.html More work will be needed to make bridge filtering work correctly with the memory API.
