2014-03-11pc: avoid duplicate names for ROM MRsMichael S. Tsirkin3-4/+8
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.

2014-03-09qemu: x86: ignore ioapic polarityGabriel L. Somlo1-3/+0
Both QEMU and KVM have already accumulated a significant number of optimizations based on the hard-coded assumption that ioapic polarity will always use the ActiveHigh convention, where the logical and physical states of level-triggered irq lines always match (i.e., active(asserted) == high == 1, inactive == low == 0). QEMU guests are expected to follow directions given via ACPI and configure the ioapic with polarity 0 (ActiveHigh). However, even when misbehaving guests (e.g. OS X <= 10.9) set the ioapic polarity to 1 (ActiveLow), QEMU will still use the ActiveHigh signaling convention when interfacing with the emulated ioapic. This patch modifies the emulated ioapic to completely ignore polarity as set by the guest OS, enabling misbehaving guests to work alongside those which comply with the ActiveHigh polarity specified by QEMU's ACPI tables.

2014-03-09pam: partly fix write-only modeHervé Poussineau1-1/+1
In write-only mode, writes are forwarded to RAM, while reads should not be handled (ie should return 0xff). Assume that in this mode, no read access is ever done, as they shouldn't give any sensible result. So, in write-only mode, alias PAM region to RAM, instead of PCI memory (which can even be mapped to some device!) This fixes Award BIOS, which use this mode to shadow system BIOS and video BIOS.

2014-03-09acpi-build: append description for non-hotplugMichael S. Tsirkin7-264/+500
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.

This makes use of @cpu_dt_id and related API in: 1. emulated XICS hypercall handlers as they receive fixed CPU indexes; 2. XICS-KVM to enable in-kernel XICS on right CPU; 3. device-tree renderer. This removes @cpu_index fixup as @cpu_dt_id is used instead so QEMU monitor can accept command-line CPU indexes again. This changes kvm_arch_vcpu_id() to use ppc_get_vcpu_dt_id() as at the moment KVM CPU id and device tree ID are calculated using the same algorithm.

2014-03-05target-ppc: add PowerPCCPU::cpu_dt_idAlexey Kardashevskiy1-0/+22
Normally CPUState::cpu_index is used to pick the right CPU for various operations. However default consecutive numbering does not always work for POWERPC. These indexes are reflected in /proc/device-tree/cpus/PowerPC,POWER7@XX and used to call KVM VCPU's ioctls. In order to achieve this, kvmppc_fixup_cpu() was introduced. Roughly speaking, it multiplies cpu_index by the number of threads per core. This approach has disadvantages such as: 1. NUMA configuration stays broken after the fixup; 2. CPU-targeted commands from the QEMU Monitor do not work properly as CPU indexes have been fixed and there is no clear way for the user to know what the new CPU indexes are. This introduces a @cpu_dt_id field in the CPUPPCState struct which is initialized from @cpu_index by default and can be fixed later to meet the device tree requirements. This adds an API to handle @cpu_dt_id. This removes kvmppc_fixup_cpu() as it is not more needed, @cpu_dt_id is calculated in ppc_cpu_realize(). This will be used later in machine code.

Without this we get the below error when trying to read the guest address (gdb) x/10 do_fork 0xc000000000098660 <do_fork>: Cannot access memory at address 0xc000000000098660 (gdb) Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> [ fixes for 32 bit build (casts!), ldq_phys() API change, Greg Kurz <gkurz@linux.vnet.ibm.com ] Signed-off-by: Greg Kurz <gkurz@linux.vnet.ibm.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2014-03-05target-ppc: Fix htab_mask calculationAneesh Kumar K.V2-5/+22
Correctly update the htab_mask using the return value of KVM_PPC_ALLOCATE_HTAB ioctl. Also we don't update sdr1 on GET_SREGS for HV. We check for external htab and if found true, we don't need to update sdr1 Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> [ fixed pte group offset computation in ppc_hash64_htab_lookup() that caused TCG to fail, Greg Kurz <gkurz@linux.vnet.ibm.com> ] Signed-off-by: Greg Kurz <gkurz@linux.vnet.ibm.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2014-03-05PPC: sPAPR: Only use getpagesize() when we run with kvmAlexander Graf1-1/+12
We currently size the msi window trap page according to the host's page size so that we poke a working hole into a memory slot in case we overlap. However, this is only ever necessary with KVM active. Without KVM, we should rather try to be host platform agnostic and use a constant size: 4k. This fixes a build breakage on win32 hosts.

2014-03-05spapr-vlan: flush queue whenever can_receive can go from false to trueAlexey Kardashevskiy1-0/+2
When the guests adds buffers to receive queue, the network device should flush its queue of pending packets. This is done with qemu_flush_queued_packets. This adds a call to qemu_flush_queued_packets() which wakes up the main loop and let QEMU update the network device status which now is "can receive". The patch basically does the same thing as e8b4c68 does.

2014-03-05qdev: Keep global allocation counter per busAlexander Graf2-8/+20
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 Kardashevskiy2-8/+26
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.

2014-03-05spapr: support only ELF kernel imagesAlexey Kardashevskiy1-5/+0
Currently everybody uses ELF kernel images with "-kernel" option on pseries machine but QEMU still tries to boot from an image even it fails to recognize it is ELF. This produces undefined behaviour if the user tries a kernel image compiled for another architecture. This removes support of raw kernel images.
