2012-10-30aio: introduce AioContext, move bottom halves therePaolo Bonzini1-0/+1
Start introducing AioContext, which will let us remove globals from aio.c/async.c, and introduce multiple I/O threads. The bottom half functions now take an additional AioContext argument. A bottom half is created with a specific AioContext that remains the same throughout the lifetime. qemu_bh_new is just a wrapper that uses a global context.

2012-10-23Rename target_phys_addr_t to hwaddrAvi Kivity325-1719/+1719
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are reserved) and its purpose doesn't match the name (most target_phys_addr_t addresses are not target specific). Replace it with a finger-friendly, standards conformant hwaddr. Outstanding patchsets can be fixed up with the command git rebase -i --exec 'find -name "*.[ch]" | xargs s/target_phys_addr_t/hwaddr/g' origin Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-10-22pci: honor PCI_COMMAND_MASTERAvi Kivity2-2/+12
Currently we ignore PCI_COMMAND_MASTER completely: DMA succeeds even when the bit is clear. Honor PCI_COMMAND_MASTER by inserting a memory region into the device's bus master address space, and tying its enable status to PCI_COMMAND_MASTER. Tested using setpci -s 03 COMMAND=3 while a ping was running on a NIC in slot 3. The kernel (Linux) detected the stall and recovered after the command setpci -s 03 COMMAND=7 was issued.

2012-10-22pci: give each device its own address spaceAvi Kivity2-0/+15
Accesses from different devices can resolve differently (depending on bridge settings, iommus, and PCI_COMMAND_MASTER), so set up an address space for each device. Currently iommus are expressed outside the memory API, so this doesn't work if an iommu is present. Signed-off-by: Avi Kivity <avi@redhat.com>
2012-10-22dma: make dma access its own address spaceAvi Kivity1-1/+2

2012-10-20create struct for machine initialization argumentsEduardo Habkost56-412/+511
This should help us to: - More easily add or remove machine initialization arguments without having to change every single machine init function; - More easily make mechanical changes involving the machine init functions in the future; - Let machine initialization forward the init arguments to other functions more easily. This change was half-mechanical process: first the struct was added with the local ram_size, boot_device, kernel_*, initrd_*, and cpu_model local variable initialization to all functions. Then the compiler helped me locate the local variables that are unused, so they could be removed. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2012-10-17i440fx: avoid destroying memory regions within a transactionAvi Kivity1-34/+35
Calling memory_region_destroy() within a transaction is illegal, since the memory API is allowed to continue to dispatch to a region until the transaction commits. 440fx does that however when managing PAM registers. This bug is benign, since the regions are all aliases (which the memory core tends to throw anyway), and since we don't do concurrent dispatch yet, but instead of relying on that, tighten ship ahead of the coming concurrency storm. Fix by having a predefined set of regions, of which one will be enabled at any time. Signed-off-by: Avi Kivity <avi@redhat.com>
