2013-09-02spapr-pci: rework MSI/MSIXAlexey Kardashevskiy
On the sPAPR platform a guest allocates MSI/MSIX vectors via RTAS hypercalls which return global IRQ numbers to a guest so it only operates with those and never touches MSIMessage. Therefore MSIMessage handling is completely hidden in QEMU. Previously every sPAPR PCI host bridge implemented its own MSI window to catch msi_notify()/msix_notify() calls from QEMU devices (virtio-pci or vfio) and route them to the guest via qemu_pulse_irq(). MSIMessage used to be encoded as: .addr - address within the PHB MSI window; .data - the device index on PHB plus vector number. The MSI MR write function translated this MSIMessage to a global IRQ number and called qemu_pulse_irq(). However the total number of IRQs is not really big (at the moment it is 1024 IRQs starting from 4096) and even 16bit data field of MSIMessage seems to be enough to store an IRQ number there. This simplifies MSI handling in sPAPR PHB. Specifically, this does: 1. remove a MSI window from a PHB; 2. add a single memory region for all MSIs to sPAPREnvironment and spapr_pci_msi_init() to initialize it; 3. encode MSIMessage as: * .addr - a fixed address of SPAPR_PCI_MSI_WINDOW==0x40000000000ULL; * .data as an IRQ number. 4. change IRQ allocator to align first IRQ number in a block for MSI. MSI uses lower bits to specify the vector number so the first IRQ has to be aligned. MSIX does not need any special allocator though.

2013-09-01pc: reduce duplication, fix PIIX descriptionsMichael S. Tsirkin
We have a lot of code duplication between machine types, this increases with each new machine type and each new field. This has already introduced a minor bug: description for pc-1.3 says "Standard PC" while description for pc-1.4 is "Standard PC (i440FX + PIIX, 1996)" which makes you think 1.3 is somehow more standard, or newer, while in fact it's a revision of the same PC. This patch addresses this issue by using macros, along the lines used by PC_COMPAT_X_X - only for non-property options. The approach can extend to non-PC machine types.

2013-08-30qcow2: Metadata overlap checksMax Reitz
Two new functions are added; the first one checks a given range in the image file for overlaps with metadata (main header, L1 tables, L2 tables, refcount table and blocks). The second one should be used immediately before writing to the image file as it calls the first function and, upon collision, marks the image as corrupt and makes the BDS unusable, thereby preventing further access. Both functions take a bitmask argument specifying the structures which should be checked for overlaps, making it possible to also check metadata writes against colliding with other structures.

2013-08-28hw: Clean up bogus default boot orderMarkus Armbruster
We set default boot order "cad" in every single machine definition except "pseries" and "moxiesim", even though very few boards actually care for boot order, and "cad" makes sense for even fewer. Machines that care: * pc and its variants Accept up to three letters 'a', 'b' (undocumented alias for 'a'), 'c', 'd' and 'n'. Reject all others (fatal with -boot). * nseries (n800, n810) Check whether order starts with 'n'. Silently ignored otherwise. * prep, g3beige, mac99 Extract the first character the machine understands (subset of 'a'..'f'). Silently ignored otherwise. * spapr Accept an arbitrary string (vl.c restricts it to contain only 'a'..'p', no duplicates). * sun4[mdc] Use the first character. Silently ignored otherwise. Strip characters these machines ignore from their default boot order. For all other machines, remove the unused default boot order alltogether. Note that my rename of QEMUMachine member boot_order to default_boot_order and QEMUMachineInitArgs member boot_device to boot_order has a welcome side effect: it makes every use of boot orders visible in this patch, for easy review.

2013-08-27pc: fix regression for 64 bit PCI memoryMichael S. Tsirkin
commit 398489018183d613306ab022653552247d93919f pc: limit 64 bit hole to 2G by default introduced a way for management to control the window allocated to the 64 bit PCI hole. This is useful, but existing management tools do not know how to set this property. As a result, e.g. specifying a large ivshmem device with size > 4G is broken by default. For example this configuration no longer works: -device ivshmem,size=4294967296,chardev=cfoo -chardev socket,path=/tmp/sock,id=cfoo,server,nowait Fix this by detecting that hole size was not specified and defaulting to the backwards-compatible value of 1 << 62.

2013-08-27pci: Introduce helper to retrieve a PCI device's DMA address spaceAlexey Kardashevskiy
A PCI device's DMA address space (possibly an IOMMU) is returned by a method on the PCIBus. At the moment that only has one caller, so the method is simply open coded. We'll need another caller for VFIO, so this patch introduces a helper/wrapper function. If IOMMU is not set, the pci_device_iommu_address_space() function returns the parent's IOMMU skipping the "bus master" address space as otherwise proper emulation would require more effort for no benefit.

2013-08-22aio / timers: Split QEMUClock into QEMUClock and QEMUTimerListAlex Bligh
Split QEMUClock into QEMUClock and QEMUTimerList so that we can have more than one QEMUTimerList associated with the same clock. Introduce a main_loop_timerlist concept and make existing qemu_clock_* calls that actually should operate on a QEMUTimerList call the relevant QEMUTimerList implementations, using the clock's default timerlist. This vastly reduces the invasiveness of this change and means the API stays constant for existing users. Introduce a list of QEMUTimerLists associated with each clock so that reenabling the clock can cause all the notifiers to be called. Note the code to do the notifications is added in a later patch. Switch QEMUClockType to an enum. Remove global variables vm_clock, host_clock and rt_clock and add compatibility defines. Do not fix qemu_next_alarm_deadline as it's going to be deleted. Add qemu_clock_use_for_deadline to indicate whether a particular clock should be used for deadline calculations. When use_icount is true, vm_clock should not be used for deadline calculations as it does not contain a nanosecond count. Instead, icount timeouts come from the execution thread doing aio_notify or qemu_notify as appropriate. This function is used in the next patch.
