When having code like this: static PCIDeviceInfo piix_ide_info[] = { { .qdev.name = "piix3-ide", .qdev.size = sizeof(PCIIDEState), .qdev.no_user = 1, .no_hotplug = 1, .init = pci_piix_ide_initfn, .vendor_id = PCI_VENDOR_ID_INTEL, .device_id = PCI_DEVICE_ID_INTEL_82371SB_1, .class_id = PCI_CLASS_STORAGE_IDE, },{ .qdev.name = "piix4-ide", .qdev.size = sizeof(PCIIDEState), .qdev.no_user = 1, .no_hotplug = 1, .init = pci_piix_ide_initfn, .vendor_id = PCI_VENDOR_ID_INTEL, .device_id = PCI_DEVICE_ID_INTEL_82371AB, .class_id = PCI_CLASS_STORAGE_IDE, },{ /* end of list */ } }; checkpatch currently errors out, claiming that spaces need to follow commas. However, this particular style of defining structs is pretty common in qemu code and very readable. So let's declare it as supported for the above case.

qemu_ram_ptr_length should take ram_addr_t as argument rather than target_phys_addr_t because is doing comparisons with RAMBlock addresses. cpu_physical_memory_map should create a ram_addr_t address to pass to qemu_ram_ptr_length from PhysPageDesc phys_offset. Remove code after abort() in qemu_ram_ptr_length. Changes in v2: - handle 0 size in qemu_ram_ptr_length; - rename addr1 to raddr; - initialize raddr to ULONG_MAX.

When disk is a cdrom and the drive is empty the "params" node in xenstore might be missing completely: cope with it instead of segfaulting. Updated in v2: - actually removed the strchr(blkdev->params, ':') that caused the segfault; - free all the allocated strings from xenstore before returning; Updated in v3: - set blkdev fields to NULL after free'ing them.

Register the vkbd backend even when running as device emulator for HVM guests: it is useful because it doesn't need a frequent timer like usb. Check whether the XenInput DisplayState has been set in the initialise state, rather than the input state. In case the DisplayState hasn't been set and there is no vfb for this domain, then set the XenInput DisplayState to the default one. Changed in v2: - use qemu_free instead of free; Signed-off-by: NStefano Stabellini <stefano.stabellini@eu.citrix.com> Signed-off-by: NAlexander Graf <agraf@suse.de>

Both the signal thread (via sigwait()) and the cpu thread (via a normal signal handler) were attempting to catch SIG_IPI. This resulted in random freezes under Darwin. This patch separates SIG_IPI from the rest of the signals handled by the signal thread, because it is independently caught by the cpu thread.

Changes since v1: - take pthread_sigmask() out of the ifdef as it is now common to both parts. This fix effectively blocks, in the main thread, the signals handled by signalfd or the compatibility signal thread. This way, such signals are received synchronously in the main thread through sigfd_handler() instead of triggering the signal handler directly, asynchronously.

Recent compilers look deep into cpu_exec, find longjmp as a noreturn function and decide to smash some stack variables as they won't be used again. This may lead to env becoming invalid after return from setjmp, causing crashes. Fix it by reloading env from cpu_single_env in that case.

The target-arm frontend's worst-case TCG ops per instr is 194 (and in general many of the "load multiple registers" ARM instructions generate more than 100 TCG ops). Raise MAX_OP_PER_INSTR accordingly to avoid possible buffer overruns. Since it doesn't make any sense for the "64 bit guest on 32 bit host" case to have a smaller limit than the normal case, we collapse the two cases back into each other again. (This increase costs us about 14K in extra static buffer space and 21K of extra margin at the end of a 32MB codegen buffer.)

When calculating the point at which we should not try to put another TB into the code gen buffer, we have to allow not just for OPC_MAX_SIZE but OPC_BUF_SIZE. This is because the target translate.c will only stop when an instruction has put it past the OPC_MAX_SIZE limit, so we have to include the MAX_OP_PER_INSTR margin which that final insn might have used.

Device code some times needs to access physical memory and does that through the ld./st._phys functions. However, these are the exact same functions that the CPU uses to access memory, which means they will be endianness swapped depending on the target CPU. However, devices don't know about the CPU's endianness, but instead access memory directly using their own interface to the memory bus, so they need some way to read data with their native endianness. This patch adds _le and _be functions to ld./st._phys. Signed-off-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NBlue Swirl <blauwirbel@gmail.com>
