2013-04-04qemu-char: Call fe_claim / fe_release when not using qdev chr propertiesHans de Goede
chardev-frontends need to explictly check, increase and decrement the avail_connections "property" of the chardev when they are not using a qdev-chardev-property for the chardev. This fixes things like: qemu-kvm -chardev stdio,id=foo -device isa-serial,chardev=foo \ -mon chardev=foo Working, where they should fail. Most of the changes here are due to old hardware emulation code which is using serial_hds directly rather then a qdev-chardev-property.

2013-04-03target-i386: Check for host features before filter_features_for_kvm()Eduardo Habkost
commit 5ec01c2e96910e1588d1a0de8609b9dda7618c7f broke "-cpu ..,enforce", as it has moved kvm_check_features_against_host() after the filter_features_for_kvm() call. filter_features_for_kvm() removes all features not supported by the host, so this effectively made kvm_check_features_against_host() impossible to fail. This patch changes the call so we check for host feature support before filtering the feature bits.

2013-04-03xen-mapcache: pass the right size argument to test_bitsHanweidong
Compute the correct size for test_bits(). qemu_get_ram_ptr() and qemu_safe_ram_ptr() will call xen_map_cache() with size is 0 if the requested address is in the RAM. Then xen_map_cache() will pass the size 0 to test_bits() for checking if the corresponding pfn was mapped in cache. But test_bits() will always return 1 when size is 0 without any bit testing. Actually, for this case, test_bits should check one bit. So this patch introduced a __test_bit_size which is greater than 0 and a multiple of XC_PAGE_SIZE, then test_bits can work correctly with __test_bit_size >> XC_PAGE_SHIFT as its size.

2013-04-02chardev: clear O_NONBLOCK on SCM_RIGHTS file descriptorsStefan Hajnoczi
When we receive a file descriptor over a UNIX domain socket the O_NONBLOCK flag is preserved. Clear the O_NONBLOCK flag and rely on QEMU file descriptor users like migration, SPICE, VNC, block layer, and others to set non-blocking only when necessary. This change ensures we don't accidentally expose O_NONBLOCK in the QMP API. QMP clients should not need to get the non-blocking state "correct". A recent real-world example was when libvirt passed a non-blocking TCP socket for migration where we expected a blocking socket. The source QEMU produced a corrupted migration stream since its code did not cope with non-blocking sockets.

2013-04-02net: ensure "socket" backend uses non-blocking fdsStefan Hajnoczi
There are several code paths in net_init_socket() depending on how the socket is created: file descriptor passing, UDP multicast, TCP, or UDP. Some of these support both listen and connect. Not all code paths set the socket to non-blocking. This patch addresses the file descriptor passing and UDP cases which were missing socket_set_nonblock(fd) calls. I considered moving socket_set_nonblock(fd) to a central location but it turns out the code paths are different enough to require non-blocking at different places.

2013-04-01qemu vfio-pci: Graphics device quirksAlex Williamson
Graphics cards have a number of different backdoors. Some of these are alternative ways to get PCI BAR addresses, some of them are complete mirrors of PCI config space available through MMIO and I/O port access. These quirks cover a number of ATI Radeon and Nvidia devices. On the ATI/AMD side, this should enable HD5450 and HD7850 and hopefully a host of devices around those generations. For Nvidia, my card selection is much more dated. A 8400gs works well with both the Window shipped driver and the Nvidia downloaded driver. A 7300le works as well, with the caveat that generating the Window experience index with the Nvidia driver causes the card to reset several times before generating a BSOD. An NVS 290 card seems to run well with the shipped Windows driver, but generates a BSOD with the Nvidia driver. All of the Nvidia devices work with the Linux Nvidia proprietary driver and nouveau, the HD5450 works with either radeon or fglrx, HD7850 works with vesa and fglrx (not supported by radeon). Extremely limited 3D testing. Device reset is also an issue with graphics. It's unfortunately very common that the devices offer no means to reset the card or doesn't seem effective. Nvidia devices are pretty good about being able to get the device to a working state through the VGA BIOS init, Radeon devices less so, and often require a host reboot. Work remains to be done here.

2013-04-01qemu vfio-pci: Add support for VGA MMIO and I/O port accessAlex Williamson
Most VGA cards need some kind of quirk to fully operate since they hide backdoors to get to other registers outside of PCI config space within the registers, but this provides the base infrastructure. If we could identity map PCI resources for assigned devices we would need a lot fewer quirks. To enable this, use a kernel side vfio-pci driver that incorporates VGA support (v3.9), and use the -vga none option and add the x-vga=on option for the vfio-pci device. The "x-" denotes this as an experimental feature. You may also need to use a cached copy of the VGA BIOS for your device, passing it to vfio-pci using the romfile= option.

2013-04-01vfio-pci: Add PCIe capability mangling based on bus typeAlex Williamson
Windows seems to pay particular interest to the PCIe header type of devices and will fail to load drivers if we attach Endpoint devices or Legacy Endpoint devices to the Root Complex. We can use pci_bus_is_express and pci_bus_is_root to determine the bus type and mangle the type appropriately: * Legacy PCI * No change, capability is unmodified for compatibility. * PCI Express * Integrated Root Complex Endpoint -> Endpoint * PCI Express Root Complex * Endpoint -> Integrated Root Complex Endpoint * Legacy Endpoint -> none, capability hidden We also take this opportunity to explicitly limit supported devices to Endpoints, Legacy Endpoints, and Root Complex Integrated Endpoints. We don't currently have support for other types and users often cause themselves problems by assigning them. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2013-04-01vfio-pci: Generalize PCI config manglingAlex Williamson
Kernel-side vfio virtualizes all of config space, but some parts are unique to Qemu. For instance we may or may not expose the ROM BAR, Qemu manages MSI/MSIX, and Qemu manages the multi-function bit so that single function devices can appear as multi-function and vica versa. Generalize this into a bitmap of Qemu emulated bits. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
