2014-03-11pc: avoid duplicate names for ROM MRsMichael S. Tsirkin
Since commit 04920fc0faa4760f9c4fc0e73b992b768099be70 loader: store FW CFG ROM files in RAM RAM MRs including ROM files in FW CFGs are created and named using the file basename. This becomes problematic if these names are supplied by user, since the basename might not be unique. There are two cases we care about: - option-rom flag. - option ROM for devices. This triggers e.g. when using rombar=0. At the moment we get an assert. E.g qemu -option-rom /usr/share/ipxe/8086100e.rom -option-rom /usr/share/ipxe.efi/8086100e.rom RAMBlock "/rom@genroms/8086100e.rom" already registered, abort! This is a regression from 1.6. For now let's keep it simple and just avoid creating the MRs in case of option ROMs. when using 1.7 machine types, enable option ROMs in RAM to match that version. Signed-off-by: Michael S.

2014-03-10target-arm: Implement WFE as a yield operationPeter Maydell
Implement WFE to yield our timeslice to the next CPU. This avoids slowdowns in multicore configurations caused by one core busy-waiting on a spinlock which can't possibly be unlocked until the other core has an opportunity to run. This speeds up my test case A15 dual-core boot by a factor of three (though it is still four or five times slower than a single-core boot).

2014-03-09memory_region_present: return false if address is not found in child ↵Igor Mammedov
MemoryRegion Windows XP shows COM2 port as non functional in "Device Manager" although no COM2 port backing device is present in QEMU. This regression is really due to 3bb28b7208b349e7a1b326e3c6ef9efac1d462bf? memory: Provide separate handling of unassigned io ports accesses That is caused by the fact that QEMU reports to OSPM that device is present by setting 5th bit in PII4XPM.pci_conf[0x67] register when COM2 doesn't exist. It happens due to memory_region_present(io_as, 0x2f8) returning false positive since 0x2f8 address eventually translates into catchall io_as address space. Fix memory_region_present(parent, addr) by returning true only if addr maps into a MemoryRegion within parent (excluding parent itself), to match its doc comment. While at it fix copy/paste error in memory_region_present() doc comment. Note: this is a temporary hack: we really need better handling for unassigned regions, we should avoid fallback regions since they are bad for performance (breaking radix tree assumption that the data structure is sparsely populated); for memory we need to fix this to implement PCI master abort properly, anyway.

2014-03-05qdev: Keep global allocation counter per busAlexander Graf
When we have 2 separate qdev devices that both create a qbus of the same type without specifying a bus name or device name, we end up with two buses of the same name, such as ide.0 on the Mac machines: dev: macio-ide, id "" bus: ide.0 type IDE dev: macio-ide, id "" bus: ide.0 type IDE If we now spawn a device that connects to a ide.0 the last created bus gets the device, with the first created bus inaccessible to the command line. After some discussion on IRC we concluded that the best quick fix way forward for this is to make automated bus-class type based allocation count a global counter. That's what this patch implements. With this we instead get dev: macio-ide, id "" bus: ide.1 type IDE dev: macio-ide, id "" bus: ide.0 type IDE on the example mentioned above. This also means that if you did -device ...,bus=ide.0 you got a device on the first bus (the last created one) before this patch and get that device on the second one (the first created one) now. Breaks migration unless you change bus=ide.0 to bus=ide.1 on the destination. This is intended and makes the bus enumeration work as expected. As per review request follows a list of otherwise affected boards and the reasoning for the conclusion that they are ok: target machine bus id times ------ ------- ------ ----- aarch64 n800 i2c-bus.0 2 aarch64 n810 i2c-bus.0 2 arm n800 i2c-bus.0 2 arm n810 i2c-bus.0 2 -> Devices are only created explicitly on one of the two buses, using s->mpu->i2c[0], so no change to the guest. aarch64 vexpress-a15 virtio-mmio-bus.0 4 aarch64 vexpress-a9 virtio-mmio-bus.0 4 aarch64 virt virtio-mmio-bus.0 32 arm vexpress-a15 virtio-mmio-bus.0 4 arm vexpress-a9 virtio-mmio-bus.0 4 arm virt virtio-mmio-bus.0 32 -> Makes -device bus= work for all virtio-mmio buses. Breaks migration. Workaround for migration from old to new: specify virtio-mmio-bus.4 or .32 respectively rather than .0 on the destination. aarch64 xilinx-zynq-a9 usb-bus.0 2 arm xilinx-zynq-a9 usb-bus.0 2 mips64el fulong2e usb-bus.0 2 -> Normal USB operation not affected. Migration driver needs command line to use the other bus. i386 isapc ide.0 2 x86_64 isapc ide.0 2 mips mips ide.0 2 mips64 mips ide.0 2 mips64el mips ide.0 2 mipsel mips ide.0 2 ppc g3beige ide.0 2 ppc mac99 ide.0 2 ppc prep ide.0 2 ppc64 g3beige ide.0 2 ppc64 mac99 ide.0 2 ppc64 prep ide.0 2 -> Makes -device bus= work for all IDE buses.

2014-03-05elf-loader: add more return codesAlexey Kardashevskiy
The existing load_elf() just returns -1 if it fails to load ELF. However it could be smarter than this and tell more about the failure such as wrong endianness or incompatible platform. This adds additional return codes for wrong architecture, wrong endianness and if the image is not ELF at all. This adds a load_elf_strerror() helper to convert return codes into string messages. This fixes handling of what load_elf() returns for s390x, other callers just check the return value for <0 and this remains unchanged.

2014-03-05KVM: Split QEMUMachine typedef into separate headerAlexander Graf
Older gcc versions (such as the one in SLES11) get confused when you declare a typedef on the same struct twice. To work around that limitation, let's extract the QEMUMachine typedef into a separate header file that is guarded by preprocessor duplicate include checks. This fixes the following type of compile errors for me: In file included from vl.c:125: include/hw/xen/xen.h:39: error: redefinition of typedef "QEMUMachine" include/sysemu/kvm.h:155: error: previous declaration of "QEMUMachine" was here Signed-off-by: Alexander Graf <agraf@suse.de>

flatten format will be used when writing kdump-compressed format. The format is also used by makedumpfile, you can refer to the following URL to get more detailed information about flatten format of kdump-compressed format: http://sourceforge.net/projects/makedumpfile/ The two functions here are used to write start flat header and end flat header to vmcore, and they will be called later when flatten format is used. struct MakedumpfileHeader stored at the head of vmcore is used to indicate the vmcore is in flatten format. struct MakedumpfileHeader { char signature[16]; /* = "makedumpfile" */ int64_t type; /* = 1 */ int64_t version; /* = 1 */ }; And struct MakedumpfileDataHeader, with offset and buf_size set to -1, is used to indicate the end of vmcore in flatten format. struct MakedumpfileDataHeader { int64_t offset; /* = -1 */ int64_t buf_size; /* = -1 */ }; Signed-off-by: Qiao Nuohan <qiaonuohan@cn.fujitsu.com> Reviewed-by: Laszlo Ersek <lersek@redhat.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
