2019-06-03pca9552-test: do not rely on state across testsPaolo Bonzini
receive_autoinc is relying on the LED state that is set by send_and_receive. Stop doing that, because qgraph resets the machine between tests. Reviewed-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2019-06-03libqos: fix omap-i2c receiving more than 4 bytesPaolo Bonzini
If more than 4 bytes are received, the FIFO cannot host the entire contents of the transfer and STP will be nonzero before entering the transfer loop. Also, CNT will contain the number of bytes left to be transferred instead of the total number of bytes in the transfer. (Reverse engineered from the omap_i2c.c source code; no available datasheet). This will fix ds1338-test for omap-i2c. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2019-06-03libqos: move common i2c code to libqosPaolo Bonzini
The functions to read/write 8-bit or 16-bit registers are the same in tmp105 and pca9552 tests, and in fact they are a special case of "read block"/"write block" functionality; read block in turn is used in ds1338-test. Move everything inside libqos-test, removing the duplication. Account for the small differences by adding to tmp105-test.c the "read register after writing" behavior that is specific to it.

2019-06-03qgraph: fix qos_node_contains with optionsPaolo Bonzini
Currently, if qos_node_contains was passed options, it would still create an edge without any options. Instead, in that case NULL acts as a terminator. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2019-06-03qgraph: allow extra_device_opts on contains nodesPaolo Bonzini
Allow choosing the bus that the device will be placed on, in case the machine has more than one. Otherwise, the bus may not match the base address of the controller we attach it to. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2019-06-03edu: mmio: allow 64-bit accessLi Qiang
The edu spec says the MMIO area can be accessed by 64-bit. However currently the 'max_access_size' is not so the MMIO access dispatch can only access 32-bit one time.

2019-06-03vl: make -accel help to list enabled accelerators onlyWainer dos Santos Moschetta
Currently, -accel help shows all possible accelerators regardless if they are enabled in the binary or not. That is a different semantic from -cpu and -machine helps, for example. So this change makes it to list only the accelerators which support is compiled in the binary target. Note that it does not check if the accelerator is enabled in the host, so the help message's header was rewritten to emphasize that. Also qtest is not displayed given that it is used for internal testing purpose only.

2019-05-29hw/display: add vhost-user-vga & gpu-pciMarc-André Lureau
Add new virtio-gpu devices with a "vhost-user" property. The associated vhost-user backend is used to handle the virtio rings and provide rendering results thanks to the vhost-user-gpu protocol. Example usage: -object vhost-user-backend,id=vug,cmd="./vhost-user-gpu" -device vhost-user-vga,vhost-user=vug Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-id: 20190524130946.31736-10-marcandre.lureau@redhat.com Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2019-05-29virtio-gpu: split virtio-gpu, introduce virtio-gpu-baseMarc-André Lureau
Add a base class that is common to virtio-gpu and vhost-user-gpu devices. The VirtIOGPUBase base class provides common functionalities necessary for both virtio-gpu and vhost-user-gpu: - common configuration (max-outputs, initial resolution, flags) - virtio device initialization, including queue setup - device pre-conditions checks (iommu) - migration blocker - virtio device callbacks - hooking up to qemu display subsystem - a few common helper functions to reset the device, retrieve display informations - a class callback to unblock the rendering (for GL updates) What is left to the virtio-gpu subdevice to take care of, in short, are all the virtio queues handling, command processing and migration.

2019-05-29vhost-user: add vhost_user_gpu_set_socket()Marc-André Lureau
Add a new vhost-user message to give a unix socket to a vhost-user backend for GPU display updates. Back when I started that work, I added a new GPU channel because the vhost-user protocol wasn't bidirectional. Since then, there is a vhost-user-slave channel for the slave to send requests to the master. We could extend it with GPU messages. However, the GPU protocol is quite orthogonal to vhost-user, thus I chose to have a new dedicated channel. See vhost-user-gpu.rst for the protocol details.

2019-05-29ppc/pnv: add dummy XSCOM registers for PRD initializationCédric Le Goater

2019-05-29ppc/pnv: introduce new skiboot platform propertiesCédric Le Goater
Newer skiboots (after 6.3) support QEMU platforms that have characteristics closer to real OpenPOWER systems. The CPU type is used to define the BMC drivers: Aspeed AST2400 for POWER8 processors and AST2500 for POWER9s. Advertise the new platform property names, "qemu,powernv8" and "qemu,powernv9", using the CPU type chosen for the QEMU PowerNV machine. Also, advertise the original platform name "qemu,powernv" in case of POWER8 processors for compatibility with older skiboots.

2019-05-29spapr: Don't migrate the hpt_maxpagesize cap to older machine typesGreg Kurz
Commit 0b8c89be7f7b added the hpt_maxpagesize capability to the migration stream. This is okay for new machine types but it breaks backward migration to older QEMUs, which don't expect the extra subsection. Add a compatibility boolean flag to the sPAPR machine class and use it to skip migration of the capability for machine types 4.0 and older. This fixes migration to an older QEMU. Note that the destination will emit a warning: qemu-system-ppc64: warning: cap-hpt-max-page-size lower level (16) in incoming stream than on destination (24) This is expected and harmless though. It is okay to migrate from a lower HPT maximum page size (64k) to a greater one (16M).

2019-05-29spapr: change default interrupt mode to 'dual'Cédric Le Goater
Now that XIVE support is complete (QEMU emulated and KVM devices), change the pseries machine to advertise both interrupt modes: XICS (P7/P8) and XIVE (P9). The machine default interrupt modes depends on the version. Current settings are: pseries default interrupt mode 4.1 dual 4.0 xics 3.1 xics 3.0 legacy xics (different IRQ number space layout) Signed-off-by: Cédric Le Goater <clg@kaod.org> Message-Id: <20190522074016.10521-3-clg@kaod.org> Reviewed-by: Greg Kurz <groug@kaod.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2019-05-29spapr/xive: fix multiple resets when using the 'dual' interrupt modeCédric Le Goater
Today, when a reset occurs on a pseries machine using the 'dual' interrupt mode, the KVM devices are released and recreated depending on the interrupt mode selected by CAS. If XIVE is selected, the SysBus memory regions of the SpaprXive model are initialized by the KVM backend initialization routine each time a reset occurs. This leads to a crash after a couple of resets because the machine reaches the QDEV_MAX_MMIO limit of SysBusDevice : qemu-system-ppc64: hw/core/sysbus.c:193: sysbus_init_mmio: Assertion `dev->num_mmio < QDEV_MAX_MMIO' failed. To fix, initialize the SysBus memory regions in spapr_xive_realize() called only once and remove the same inits from the QEMU and KVM backend initialization routines which are called at each reset.
