2015-03-04virtio-balloon: Fix balloon not working correctly when hotplug memoryzhanghailiang
When do memory balloon, it takes the 'ram_size' as the VM's current ram size, But 'ram_size' is the startup configured ram size, it does not take into account the hotplugged memory. As a result, the balloon result will be confused. Steps to reproduce: (1)Start VM: qemu -m size=1024,slots=4,maxmem=8G (2)In VM: #free -m : 1024M (3)qmp balloon 512M (4)In VM: #free -m : 512M (5)hotplug pc-dimm 1G (6)In VM: #free -m : 1512M (7)qmp balloon 256M (8)In VM: #free -m :1256M We expect the VM's available ram size to be 256M after 'qmp balloon 256M' command, but VM's real available ram size is 1256M. For "qmp balloon" is not performance critical code, we use function 'get_current_ram_size' to get VM's current ram size.

2015-03-04pc-dimm: add a function to calculate VM's current RAM sizezhanghailiang
The global parameter 'ram_size' does not take into account the hotplugged memory. In some codes, we use 'ram_size' as current VM's real RAM size, which is not correct. Add function 'get_current_ram_size' to calculate VM's current RAM size, it will enumerate present memory devices and also plus ram_size.

2015-03-03xhci: generate a Transfer Event for each Transfer TRB with the IOC bit setLaszlo Ersek
At the moment, when the XHCI driver in edk2 (MdeModulePkg/Bus/Pci/XhciDxe/XhciDxe.inf) runs on QEMU, with the options -device nec-usb-xhci -device usb-kbd it crashes with: ASSERT MdeModulePkg/Bus/Pci/XhciDxe/XhciSched.c(1759): TrsRing != ((void*) 0) The crash hits in the following edk2 call sequence (all files under MdeModulePkg/Bus/): UsbEnumerateNewDev() [Usb/UsbBusDxe/UsbEnumer.c] UsbBuildDescTable() [Usb/UsbBusDxe/UsbDesc.c] UsbGetDevDesc() [Usb/UsbBusDxe/UsbDesc.c] UsbCtrlGetDesc(USB_REQ_GET_DESCRIPTOR) [Usb/UsbBusDxe/UsbDesc.c] UsbCtrlRequest() [Usb/UsbBusDxe/UsbDesc.c] UsbHcControlTransfer() [Usb/UsbBusDxe/UsbUtility.c] XhcControlTransfer() [Pci/XhciDxe/Xhci.c] XhcCreateUrb() [Pci/XhciDxe/XhciSched.c] XhcCreateTransferTrb() [Pci/XhciDxe/XhciSched.c] XhcExecTransfer() [Pci/XhciDxe/XhciSched.c] XhcCheckUrbResult() [Pci/XhciDxe/XhciSched.c] // // look for TRB_TYPE_DATA_STAGE event [1] // // // Store a copy of the device descriptor, as the hub device // needs this info to configure endpoint.

The requests consists of three stages (three TRBs), setup, data, and status. The length of the response is determined in [1], namely from the transfer event that the host controller generates in response to the request's middle stage (ie. the data stage). If the length of the answer is correct (a full GET_DESCRIPTOR request takes 18 bytes), then the XHCI driver that underlies the USB bus driver "snoops" (caches) the descriptor data for later [2]. Later, the USB bus driver sends a SET_CONFIG request. The underlying XHCI driver allocates a transfer ring for the endpoint, relying on the data snooped and cached in step [2]. Finally, the USB keyboard driver submits an asynchronous interrupt transfer to manage the keyboard. As part of this it asserts [4] that the ring has been allocated in step [3]. And this ASSERT() fires. The root cause can be found in the way QEMU handles the initial GET_DESCRIPTOR request. Again, that request consists of three stages (TRBs, Transfer Request Blocks), "setup", "data", and "status". The XhcCreateTransferTrb() function sets the IOC ("Interrupt on Completion") flag in each of these TRBs. According to the XHCI specification, the host controller shall generate a Transfer Event in response to *each* individual TRB of the request that had the IOC flag set. This means that QEMU should queue three events: setup, data, and status, for edk2's XHCI driver. However, QEMU only generates two events: - one for the setup (ie. 1st) stage, - another for the status (ie. 3rd) stage. No event is generated for the middle (ie. data) stage. The loop in QEMU's xhci_xfer_report() function runs three times, but due to the "reported" variable, only the first and the last TRBs elicit events, the middle (data stage) results in no event queued. As a consequence: - When handling the GET_DESCRIPTOR request, XhcCheckUrbResult() in [1] does not update the response length from zero. - XhcControlTransfer() thinks that the response is invalid (it has zero length payload instead of 18 bytes), hence [2] is not reached; the device descriptor is not stashed for later, and the number of possible configurations is left at zero. - When handling the SET_CONFIG request, (NumConfigurations == 0) from above prevents the allocation of the endpoint's transfer ring. - When the keyboard driver tries to use the endpoint, the ASSERT() blows up. The solution is to correct the emulation in QEMU, and to generate a transfer event whenever IOC is set in a TRB. The patch replaces !reported && (IOC || foo) == !reported && IOC || !reported && foo with IOC || (!reported && foo) == IOC || !reported && foo which only changes how reported && IOC is handled. (Namely, it now generates an event.) Tested with edk2 built for "qemu-system-aarch64 -M virt" (ie. "ArmVirtualizationQemu.dsc", aka "AAVMF"), and guest Linux.

2015-03-03spice: fix invalid memory access to vga.vramRadim Krčmář
vga_common_init() doesn't allow more than 256 MiB vram size and silently shrinks any larger value. qxl_dirty_surfaces() used the unshrinked size via qxl->shadow_rom.surface0_area_size when accessing the memory, which resulted in segfault. Add a workaround for this case and an assert if it happens again. We have to bump the vga memory limit too, because 256 MiB wouldn't have allowed 8k (it requires more than 128 MiB). 1024 MiB doesn't work, but 512 MiB seems fine.

2015-03-02vfio-pci: Enable device request notification supportAlex Williamson
Linux v4.0-rc1 vfio-pci introduced a new virtual interrupt to allow the kernel to request a device from the user. When signaled, QEMU will by default attmempt to hot-unplug the device. This is a one- shot attempt with the expectation that the kernel will continue to poll for the device if it is not returned. Returning the device when requested is the expected standard model of cooperative usage, but we also add an option option to disable this feature. Initially this opt-out is set as an experimental option because we really should honor kernel requests for the device. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>

2015-03-02virtio-scsi: Allocate op blocker reason before blockingMax Reitz
s->blocker is really only used in hw/scsi/virtio-scsi.c; the only places where it is used in hw/scsi/virtio-scsi-dataplane.c is when it is allocated and when it is freed.

Manual hole in PIIX4 _CRS wasn't correct anyway since it was legacy size 0xF while current PCIHP MMIO region is of size 0x14.

2015-03-01balloon: call qdev_alias_all_properties for proxy dev in balloon class initDenis V. Lunev
The idea is that all other virtio devices are calling this helper to merge properties of the proxy device. This is the only difference in between this helper and code in inside virtio_instance_init_common. The patch should not cause any harm as property list in generic balloon code is empty. This also allows to avoid some dummy errors like fixed by this commit 91ba21208839643603e7f7fa5864723c3f371ebe Author: Gonglei <arei.gonglei@huawei.com> Date: Tue Sep 30 14:10:35 2014 +0800 virtio-balloon: fix virtio-balloon child refcount in transports Signed-off-by: Denis V.

2015-02-27Give ivshmem its own config optionDavid Gibson
Currently the ivshmem device is built whenever both PCI and KVM support are included. This patch gives it its own config option to allow easier customization of whether to include it. It's enabled by default in the same circumstances as now - when both PCI and KVM are available.

2015-02-27Create specific config option for "platform-bus"David Gibson
Currently the "platform-bus" device is included for all softmmu builds. This bridge is intended for use on any platforms that require dynamic creation of sysbus devices. However, at present it is used only for the PPC E500 target, with plans for the ARM "virt" target in the immediate future. To avoid a not-very-useful entry appearing in "qemu -device ?" output on other targets, this patch makes a specific config option for platform-bus and enables it (for now) only on ppc configurations which include E500 and on ARM (which always includes the "virt" target).

2015-02-27Add specific config options for PCI-E bridgesDavid Gibson
The i82801b11, ioh3420 and xio3130 PCI Express devices are currently included in the build unconditionally. While they could theoretically appear on any target platform with PCI-E, they're pretty unlikely to appear on platforms that aren't Intel derived. Therefore, to avoid presenting unlikely-to-be-relevant devices to the user, add config options to enable these components, and enable them by default only on x86 and arm platforms. (Note that this patch does include these for aarch64, via its inclusion of arm-softmmu.mak).

2015-02-27virtio-scsi-dataplane: Call blk_set_aio_context within BQLFam Zheng
It's not safe to call blk_set_aio_context from outside BQL because of the bdrv_drain_all there. Let's put it in the hotplug callback which will be called by qdev device realization for each scsi device attached to the bus.

2015-02-27scsi: give device a parent before setting propertiesPaolo Bonzini
This mimics what is done in qdev_device_add, and lets the device be freed in case something goes wrong. Otherwise, object_unparent returns immediately without freeing the device, which is on the other hand left in the parent bus's list of children. scsi_bus_legacy_handle_cmdline then returns an error, and the HBA is destroyed as well with object_unparent. But the lingering device that was not removed in scsi_bus_legacy_add_drive cannot be removed now either, and bus_unparent gets stuck in an infinite loop trying to empty the list of children. The right fix of course would be to assert in bus_add_child that the device already has a bus, and remove the "safety net" that adds the drive to the QOM tree in device_set_realized. I am not yet sure whether that would entail changing all callers to qdev_create (as well as isa_create and usb_create and the corresponding _try_create versions).
