2014-03-13target-i386: Enable x2apic by default on KVMEduardo Habkost
When on KVM mode, enable x2apic by default on all CPU models. Normally we try to keep the CPU model definitions as close as the real CPUs as possible, but x2apic can be emulated by KVM without host CPU support for x2apic, and it improves performance by reducing APIC access overhead. x2apic emulation is available on KVM since 2009 (Linux 2.6.32-rc1), there's no reason for not enabling x2apic by default when running KVM.

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. Tsirkin <mst@redhat.com>

2014-03-09acpi-build: append description for non-hotplugMichael S. Tsirkin
As reported in http://article.gmane.org/gmane.comp.emulators.qemu/253987 Mac OSX actually requires describing all occupied slots in ACPI - even if hotplug isn't enabled. I didn't expect this so I dropped description of all non hotpluggable slots from ACPI. As a result: before commit 99fd437dee468609de8218f0eb3b16621fb6a9c9 (enable hotplug for pci bridges), PCI cards show up in the "device tree" of OS X (System Information). E.g., on MountainLion users have: Hardware -> PCI Cards: Card Type Driver Installed Slot *ethernet Ethernet Controller Yes PCI Slot 2 pci8086,2934 USB UHC Yes PCI Slot 29 ethernet: Type: Ethernet Controller Driver Installed: Yes MSI: No Bus: PCI Slot PCI Slot 2 Vendor ID: 0x8086 Device ID: 0x100e Subsystem Vendor ID: 0x1af4 Subsystem ID: 0x1100 Revision ID: 0x0003 Hardware -> Ethernet Cards ethernet: Type: Ethernet Controller Bus: PCI Slot PCI Slot 2 Vendor ID: 0x8086 Device ID: 0x100e Subsystem Vendor ID: 0x1af4 Subsystem ID: 0x1100 Revision ID: 0x0003 BSD name: en0 Kext name: AppleIntel8254XEthernet.kext Location: /System/Library/Extensions/... Version: 3.1.1b1 After commit 99fd437dee468609de8218f0eb3b16621fb6a9c9, users get: Hardware -> PCI Cards: This computer doesn't contain any PCI cards. If you installed PCI cards, make sure they're properly installed. Hardware -> Ethernet Cards ethernet: Type: Ethernet Controller Bus: PCI Vendor ID: 0x8086 Device ID: 0x100e Subsystem Vendor ID: 0x1af4 Subsystem ID: 0x1100 Revision ID: 0x0003 BSD name: en0 Kext name: AppleIntel8254XEthernet.kext Location: /System/Library/Extensions/... Version: 3.1.1b1 Ethernet still works, but it's not showing up on the PCI bus, and it no longer thinks it's plugged in to slot #2, as it used to before the change. To fix, append description for all occupied non hotpluggable PCI slots. One need to be careful when doing this: VGA devices are now described in SSDT, so we need to drop description from DSDT. And ISA devices are used in DSDT so drop them from SSDT. Reported-by: Gabriel L. Somlo <gsomlo@gmail.com> Signed-off-by: Michael S.

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.

2014-02-10ACPI: Remove commented-out code from HPET._CRSGabriel L. Somlo
IRQNoFlags on HPET._CRS crashes WinXP because it causes the HPET to conflict with the system timer and/or the RTC. It only occurs on Apple hardware, and even there it is exposed fully only when OS X is detected (via _OSI). Recent OS X versions work on QEMU without this statement, so at this time there is no need to find a better way to conditionally include the statement.

2013-12-23piix: fix 32bit pci holeGerd Hoffmann
Make the 32bit pci hole start at end of ram, so all possible address space is covered. We used to try and make addresses aligned so they are easier to cover with MTRRs, but since they are cosmetic on KVM, this is probably not worth worrying about. Of course the firmware can use less than that. Leaving space unused is no problem, mapping pci bars outside the hole causes problems though.

2013-12-23hw/i386/pc_sysfw: support two flash drivesLaszlo Ersek
This patch allows the user to usefully specify -drive file=img_1,if=pflash,format=raw,readonly \ -drive file=img_2,if=pflash,format=raw on the command line. The flash images will be mapped under 4G in their reverse unit order -- that is, with their base addresses progressing downwards, in increasing unit order. (The unit number increases with command line order if not explicitly specified.) This accommodates the following use case: suppose that OVMF is split in two parts, a writeable host file for non-volatile variable storage, and a read-only part for bootstrap and decompressible executable code. The binary code part would be read-only, centrally managed on the host system, and passed in as unit 0. The variable store would be writeable, VM-specific, and passed in as unit 1. 00000000ffe00000-00000000ffe1ffff (prio 0, R-): system.flash1 00000000ffe20000-00000000ffffffff (prio 0, R-): system.flash0 (If the guest tries to write to the flash range that is backed by the read-only drive, pflash_update() is never called; various flash programming/erase errors are returned to the guest instead. See the callers of pflash_update(), and the initialization of "pfl->ro", in "hw/block/pflash_cfi01.c".)

2013-12-23piix: gigabyte alignment for ramGerd Hoffmann
Map 3G (i440fx) of memory below 4G, so the RAM pieces are nicely aligned to gigabyte borders. Keep old memory layout for (a) old machine types and (b) in case all memory fits below 4G and thus we don't have to split RAM into pieces in the first place. The later makes sure this change doesn't take away memory from 32bit guests. So, with i440fx and up to 3.5 GB of memory, all of it will be mapped below 4G. With more than 3.5 GB of memory 3 GB will be mapped below 4G and the remaining amount will be mapped above 4G. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Michael S.
