2017-06-15vhost-user-scsi: Introduce vhost-user-scsi host deviceFelipe Franciosi
This commit introduces a vhost-user device for SCSI. This is based on the existing vhost-scsi implementation, but done over vhost-user instead. It also uses a chardev to connect to the backend. Unlike vhost-scsi (today), VMs using vhost-user-scsi can be live migrated. To use it, start Qemu with a command line equivalent to: qemu-system-x86_64 \ -chardev socket,id=vus0,path=/tmp/vus.sock \ -device vhost-user-scsi-pci,chardev=vus0,bus=pci.0,addr=... A separate commit presents a sample application linked with libiscsi to provide a backend for vhost-user-scsi.

2017-04-24net: add FTGMAC100 supportCédric Le Goater
The FTGMAC100 device is an Ethernet controller with DMA function that can be found on Aspeed SoCs (which include NCSI). It is fully compliant with IEEE 802.3 specification for 10/100 Mbps Ethernet and IEEE 802.3z specification for 1000 Mbps Ethernet and includes Reduced Media Independent Interface (RMII) and Reduced Gigabit Media Independent Interface (RGMII) interfaces. It adopts an AHB bus interface and integrates a link list DMA engine with direct M-Bus accesses for transmitting and receiving packets. It has independent TX/RX fifos, supports half and full duplex (1000 Mbps mode only supports full duplex), flow control for full duplex and backpressure for half duplex. The FTGMAC100 also implements IP, TCP, UDP checksum offloads and supports IEEE 802.1Q VLAN tag insertion and removal. It offers high-priority transmit queue for QoS and CoS applications This model is backed with a RealTek 8211E PHY which is the chip found on the AST2500 EVB. It is complete enough to satisfy two different Linux drivers and a U-Boot driver. Not supported features are : - IEEE 802.1Q VLAN - High Priority Transmit Queue - Wake-On-LAN functions The code is based on the Coldfire Fast Ethernet Controller model.

2017-02-24hw/mips: MIPS Boston board supportPaul Burton
Introduce support for emulating the MIPS Boston development board. The Boston board is built around an FPGA & 3 PCIe controllers, one of which is connected to an Intel EG20T Platform Controller Hub. It is used during the development & debug of new CPUs and the software intended to run on them, and is essentially the successor to the older MIPS Malta board. This patch does not implement the EG20T, instead connecting an already supported ICH-9 AHCI controller. Whilst this isn't accurate it's enough for typical stock Boston software (eg. Linux kernels) to work with hard disks given that both the ICH-9 & EG20T implement the AHCI specification. Boston boards typically boot kernels in the FIT image format, and this patch will treat kernels provided to QEMU as such. When loading a kernel directly, the board code will generate minimal firmware much as the Malta board code does. This firmware will set up the CM, CPC & GIC register base addresses then set argument registers & jump to the kernel entry point. Alternatively, bootloader code may be loaded using the bios argument in which case no firmware will be generated & execution will proceed from the start of the boot code at the default MIPS boot exception vector (offset 0x1fc00000 into (c)kseg1). Currently real Boston boards are always used with FPGA bitfiles that include a Global Interrupt Controller (GIC), so the interrupt configuration is only defined for such cases. Therefore the board will only allow use of CPUs which implement the CPS components, including the GIC, and will otherwise exit with a message.

Unfortunately on 32-bit hosts we can't create boards with 2GB of RAM, and so 'make check' fails. I missed this during testing of the merge, unfortunately.

2017-02-06Allow ISA bus to be configured outDavid Gibson
Currently, the code to handle the legacy ISA bus is always included in qemu. However there are lots of platforms that don't include ISA legacy devies, and quite a few that have never used ISA legacy devices at all. This patch allows the ISA bus code to be disabled in the configuration for platforms where it doesn't make sense. For now, the default configs are adjusted to include ISA on all platforms including PCI: anything with PCI can at least in principle add an i82378 PCI->ISA bridge. Also, CONFIG_IDE_CORE which is already in pci.mak requires ISA support. We also explicitly enable ISA on some other non-PCI platforms which include ISA devices: moxie, sparc and unicore32. We may want to pare this down in future. The platforms that will lose ISA by default are: cris, lm32, microblazeel, microblaze, openrisc, s390x, tricore, xtensaeb, xtensa. As far as I can tell none of these ever used ISA. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Acked-by: Michael S.

2017-02-06Split serial-isa into its own config optionDavid Gibson
At present, the core device model code for 8250-like serial ports (serial.c) and the code for serial ports attached to ISA-style legacy IO (serial-isa.c) are both controlled by the CONFIG_SERIAL variable. There are lots and lots of embedded platforms that have 8250-like serial ports but have never had anything resembling ISA legacy IO. Therefore, split serial-isa into its own CONFIG_SERIAL_ISA option so it can be disabled for platforms where it's not appropriate. For now, I enabled CONFIG_SERIAL_ISA in every default-config where CONFIG_SERIAL is enabled, excepting microblaze, or32, and xtensa. As best as I can tell, those platforms never used legacy ISA, and also don't include PCI support (which would allow connection of a PCI->ISA bridge and/or a southbridge including legacy ISA serial ports).

It's been a long time coming due to some holidays and inconveniently timed problems with testing. So, there's a lot in here: * More POWER9 instruction implementations for TCG * The simpler parts of my CPU compatibility mode cleanup * This changes behaviour to prefer compatibility modes over "raW" mode for new machine type versions * New "40p" machine type which is essentially a modernized and cleaned up "prep". The intention is that it will replace "prep" once it has some more testing and polish. * Add pseries-2.9 machine type * Implement H_SIGNAL_SYS_RESET hypercall * Consolidate the two alternate CPU init paths in pseries by making it always go through CPU core objects to initialize CPU * A number of bugfixes and cleanups * Stop the guest timebase when the guest is stopped under KVM. This makes the guest system clock also stop when paused, which matches the x86 behaviour. * Some preliminary cleanups leading towards implementation of the POWER9 MMU. There are also some changes not strictly related to ppc code, but for its benefit: * Limit the pxi-expander-bridge (PXB) device to x86 guests only (it's essentially a hack to work around historical x86 limitations) * Some additions to the 128-bit math in host_utils, necessary for some of the new instructions. * Revise a number of qtests and enable them for ppc # gpg: Signature made Thu 02 Feb 2017 01:40:16 GMT # gpg: using RSA key 0x6C38CACA20D9B392 # gpg: Good signature from "David Gibson <david@gibson.dropbear.id.au>" # gpg: aka "David Gibson (Red Hat) <dgibson@redhat.com>" # gpg: aka "David Gibson (ozlabs.org) <dgibson@ozlabs.org>" # gpg: aka "David Gibson (kernel.org) <dwg@kernel.org>" # Primary key fingerprint: 75F4 6586 AE61 A66C C44E 87DC 6C38 CACA 20D9 B392 * remotes/dgibson/tags/ppc-for-2.9-20170202: (107 commits) hw/ppc/pnv: Use error_report instead of hw_error if a ROM file can't be found ppc/kvm: Handle the "family" CPU via alias instead of registering new types target/ppc/mmu_hash64: Fix incorrect shift value in amr calculation target/ppc/mmu_hash64: Fix printing unsigned as signed int tcg/POWER9: NOOP the cp_abort instruction target/ppc/debug: Print LPCR register value if register exists target-ppc: Add xststdc[sp, dp, qp] instructions target-ppc: Add xvtstdc[sp,dp] instructions target-ppc: Add MMU model check for booke machines ppc: switch to constants within BUILD_BUG_ON target/ppc/cpu-models: Fix/remove bad CPU aliases target/ppc: Remove unused POWERPC_FAMILY(POWER) spapr: clock should count only if vm is running ppc: Remove unused function cpu_ppc601_rtc_init() target/ppc: Add pcr_supported to POWER9 cpu class definition powerpc/cpu-models: rename ISAv3.00 logical PVR definition target-ppc: Add xvcv[hpsp, sphp] instructions target-ppc: Add xsmulqp instruction target-ppc: Add xsdivqp instruction target-ppc: Add xscvsdqp and xscvudqp instructions ... # Conflicts: # hw/pci-bridge/Makefile.objs Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2017-01-31pxb: Restrict to x86David Gibson
The PCI Expander Bridge (PXB) device is essentially a hack to allow different PCIe devices to be assigned to different NUMA nodes on x86. Each PXB is sort-of a separate PCI host bridge, except that its config space is shared with the config space of the main PCI host bridge, rather than being independent. This is only necessary if the platform doesn't (easily) allow truly independent PCI host bridges. AFAIK that's just x86. This patch makes it possible to configure PXB out of the build, and adjusts the default configs so it's only included on x86 targets.

This is just about the minimum required to enable compilation without actually executing any instructions. This contains the HPPACPU structure and the required callbacks, the gdbstub, the basic translation loop, and a translate_one function that always results in an illegal instruction.

2017-01-18target-sparc: fix up niagara machineArtyom Tarasenko
Remove the Niagara stub implementation from sun4u.c and add a machine, compatible with Legion simulator from the OpenSPARC T1 project. The machine uses the firmware supplied with the OpenSPARC T1 project, http://download.oracle.com/technetwork/systems/opensparc/OpenSPARCT1_Arch.1.5.tar.bz2 in the directory S10image/, and is able to boot the supplied Solaris 10 image. Note that for compatibility with the naming conventions for SPARC machines the new machine name is lowercase niagara.

2016-10-28ppc/pnv: add skeleton PowerNV platformBenjamin Herrenschmidt
The goal is to emulate a PowerNV system at the level of the skiboot firmware, which loads the OS and provides some runtime services. Power Systems have a lower firmware (HostBoot) that does low level system initialization, like DRAM training. This is beyond the scope of what qemu will address in a PowerNV guest. No devices yet, not even an interrupt controller. Just to get started, some RAM to load the skiboot firmware, the kernel and initrd. The device tree is fully created in the machine reset op.

2016-06-02net: Introduce e1000e device emulationDmitry Fleytman
This patch introduces emulation for the Intel 82574 adapter, AKA e1000e. This implementation is derived from the e1000 emulation code, and utilizes the TX/RX packet abstractions that were initially developed for the vmxnet3 device. Although some parts of the introduced code may be shared with e1000, the differences are substantial enough so that the only shared resources for the two devices are the definitions in hw/net/e1000_regs.h. Similarly to vmxnet3, the new device uses virtio headers for task offloads (for backends that support virtio extensions). Usage of virtio headers may be forcibly disabled via a boolean device property "vnet" (which is enabled by default). In such case task offloads will be performed in software, in the same way it is done on backends that do not support virtio headers. The device code is split into two parts: 1. hw/net/e1000e.c: QEMU-specific code for a network device; 2. hw/net/e1000e_core.[hc]: Device emulation according to the spec. The new device name is e1000e. Intel specifications for the 82574 controller are available at: http://www.intel.com/content/dam/doc/datasheet/82574l-gbe-controller-datasheet.pdf Throughput measurement results (iperf2): Fedora 22 guest, TCP, RX 4 ++------------------------------------------+ | | | X X X X X 3.5 ++ X X X X | | X | | | 3 ++ | G | X | b | | / 2.5 ++ | s | | | | 2 ++ | | | | | 1.5 X+ | | | + + + + + + + + + + + + 1 ++--+---+---+---+---+---+---+---+---+---+---+ 32 64 128 256 512 1 2 4 8 16 32 64 B B B B B KB KB KB KB KB KB KB Buffer size Fedora 22 guest, TCP, TX 18 ++-------------------------------------------+ | X | 16 ++ X X X X X | X | 14 ++ | | | 12 ++ | G | X | b 10 ++ | / | | s 8 ++ | | | 6 ++ X | | | 4 ++ | | X | 2 ++ X | X + + + + + + + + + + + 0 ++--+---+---+---+---+----+---+---+---+---+---+ 32 64 128 256 512 1 2 4 8 16 32 64 B B B B B KB KB KB KB KB KB KB Buffer size Fedora 22 guest, UDP, RX 3 ++------------------------------------------+ | X | | 2.5 ++ | | | | | 2 ++ X | G | | b | | / 1.5 ++ | s | X | | | 1 ++ | | | | X | 0.5 ++ | | X | X + + + + + 0 ++-------+--------+-------+--------+--------+ 32 64 128 256 512 1 B B B B B KB Datagram size Fedora 22 guest, UDP, TX 1 ++------------------------------------------+ | X 0.9 ++ | | | 0.8 ++ | 0.7 ++ | | | G 0.6 ++ | b | | / 0.5 ++ | s | X | 0.4 ++ | | | 0.3 ++ | 0.2 ++ X | | | 0.1 ++ X | X X + + + + 0 ++-------+--------+-------+--------+--------+ 32 64 128 256 512 1 B B B B B KB Datagram size Windows 2012R2 guest, TCP, RX 3.2 ++------------------------------------------+ | X | 3 ++ | | | 2.8 ++ | | | 2.6 ++ X | G | X X X X X b 2.4 ++ X X | / | | s 2.2 ++ | | | 2 ++ | | X X | 1.8 ++ | | | 1.6 X+ | + + + + + + + + + + + + 1.4 ++--+---+---+---+---+---+---+---+---+---+---+ 32 64 128 256 512 1 2 4 8 16 32 64 B B B B B KB KB KB KB KB KB KB Buffer size Windows 2012R2 guest, TCP, TX 14 ++-------------------------------------------+ | | | X X 12 ++ | | | 10 ++ | | | G | | b 8 ++ | / | X | s 6 ++ | | | | | 4 ++ X | | | 2 ++ | | X X X | + X X + + X X + + + + + 0 X+--+---+---+---+---+----+---+---+---+---+---+ 32 64 128 256 512 1 2 4 8 16 32 64 B B B B B KB KB KB KB KB KB KB Buffer size Windows 2012R2 guest, UDP, RX 1.6 ++------------------------------------------X | | 1.4 ++ | | | 1.2 ++ | | X | | | G 1 ++ | b | | / 0.8 ++ | s | | 0.6 ++ X | | | 0.4 ++ | | X | | | 0.2 ++ X | X + + + + + 0 ++-------+--------+-------+--------+--------+ 32 64 128 256 512 1 B B B B B KB Datagram size Windows 2012R2 guest, UDP, TX 0.6 ++------------------------------------------+ | X | | 0.5 ++ | | | | | 0.4 ++ | G | | b | | / 0.3 ++ X | s | | | | 0.2 ++ | | | | X | 0.1 ++ | | X | X X + + + + 0 ++-------+--------+-------+--------+--------+ 32 64 128 256 512 1 B B B B B KB Datagram size Signed-off-by: Dmitry Fleytman <dmitry.fleytman@ravellosystems.com> Signed-off-by: Leonid Bloch <leonid.bloch@ravellosystems.com> Reviewed-by: Michael S.

2016-03-30hw/mips: implement ITC Configuration Tags and Storage CellsLeon Alrae
Implement ITC as a single object consisting of two memory regions: 1) tag_io: ITC Configuration Tags (i.e. ITCAddressMap{0,1} registers) which are accessible by the CPU via CACHE instruction. Also adding MemoryRegion *itc_tag to the CPUMIPSState so that CACHE instruction will dispatch reads/writes directly. 2) storage_io: memory-mapped ITC Storage whose address space is configurable (i.e. enabled/remapped/resized) by writing to ITCAddressMap{0,1} registers. ITC Storage contains FIFO and Semaphore cells. Read-only FIFO bit in the ITC cell tag indicates the type of the cell. If the ITC Storage contains both types of cells then FIFOs are located before Semaphores. Since issuing thread can get blocked on the access to a cell (in E/F Synchronized and P/V Synchronized Views) each cell has a bitmap to track which threads are currently blocked.
