2013-03-18Switch to efi-enabled nic roms by defaultGerd Hoffmann
All PCI nics are switched to EFI-enabled roms by default. They are composed from three images (legacy, efi ia32 & efi x86), so classic pxe booting will continue to work. Exception: eepro100 is not switched, it uses a single rom for all emulated eepro100 variants, then goes patch the rom header on the fly with the correct PCI IDs. I doubt that will work as-is with the efi roms. Keep old roms for 1.4+older machine types via compat properties, needed because the efi-enabled roms are larger so the pci rom bar size would change.

2013-01-10Make all static TypeInfos constAndreas Färber
Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

2013-01-07virtio: backend virtqueue notifier maskingMichael S. Tsirkin
some backends (notably vhost) can mask events at their source in a way that is more efficient than masking through kvm. Specifically - masking in kvm uses rcu write side so it has high latency - in kvm on unmask we always send an interrupt masking at source does not have these issues.

2013-01-02virtio-blk: add x-data-plane=on|off performance featureStefan Hajnoczi
The virtio-blk-data-plane feature is easy to integrate into hw/virtio-blk.c. The data plane can be started and stopped similar to vhost-net. Users can take advantage of the virtio-blk-data-plane feature using the new -device virtio-blk-pci,x-data-plane=on property. The x-data-plane name was chosen because at this stage the feature is experimental and likely to see changes in the future. If the VM configuration does not support virtio-blk-data-plane an error message is printed. Although we could fall back to regular virtio-blk, I prefer the explicit approach since it prompts the user to fix their configuration if they want the performance benefit of virtio-blk-data-plane. Limitations: * Only format=raw is supported * Live migration is not supported * Block jobs, hot unplug, and other operations fail with -EBUSY * I/O throttling limits are ignored * Only Linux hosts are supported due to Linux AIO usage Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-01-02virtio-blk: restore VirtIOBlkConf->config_wce flagStefan Hajnoczi
Two slightly different versions of a patch to conditionally set VIRTIO_BLK_F_CONFIG_WCE through the "config-wce" qdev property have been applied (ea776abca and eec7f96c2). David Gibson <david@gibson.dropbear.id.au> noticed that the "config-wce" property is broken as a result and fixed it recently. The fix sets the host_features VIRTIO_BLK_F_CONFIG_WCE bit from a qdev property. Unfortunately, the virtio device then has no chance to test for the presence of the feature bit during virtio_blk_init(). Therefore, reinstate the VirtIOBlkConf->config_wce flag. Drop the duplicate qdev property to set the host_features bit. The VirtIOBlkConf->config_wce flag will be used by virtio-blk-data-plane in a later patch.

2012-12-26virtio-pci: don't poll masked vectorsMichael S. Tsirkin
At the moment, when irqfd is in use but a vector is masked, qemu will poll it and handle vector masks in userspace. Since almost no one ever looks at the pending bits, it is better to defer this until pending bits are actually read. Implement this optimization using the new poll notifier. Signed-off-by: Michael S.

2012-12-11virtio-blk: Remove duplicate property definitionDavid Gibson
For the virtio-blk device (via virtio-pci) the property "config-wce" is defined in two places. First, it's defined from the DEFINE_VIRTIO_BLK_FEATURES macro, second it's defined directly in virtio-pci, just two lines above the call to that macro. The direct definition in virtio-pci.c is broken, since it operates on the 'config_wce' field of VirtIOBlkConf, which is never used anywhere else. Therefore, this patch removes both the extra property definition and the redundant field it works on.

2012-08-17virtio-blk: hide VIRTIO_BLK_F_CONFIG_WCE from old machine typesStefan Hajnoczi
QEMU has a policy of keeping a stable guest device ABI. When new guest device features are introduced they must not change hardware info seen by existing guests. This is important because operating systems or applications may "fingerprint" the hardware and refuse to run when the hardware changes. To always get the latest guest device ABI, run with x86 machine type "pc". This patch hides the new VIRTIO_BLK_F_CONFIG_WCE virtio feature bit from existing machine types. Only pc-1.2 and later will expose this feature by default. For more info on the VIRTIO_BLK_F_CONFIG_WCE feature bit, see: commit 13e3dce068773c971ff2f19d986378c55897c4a3 Author: Paolo Bonzini <pbonzini@redhat.com> Date: Thu Aug 9 16:07:19 2012 +0200 virtio-blk: support VIRTIO_BLK_F_CONFIG_WCE Also rename VIRTIO_BLK_F_WCACHE to VIRTIO_BLK_F_WCE for consistency with the spec.

2012-08-06virtio: fix vhost handlingPaolo Bonzini
Commit b1f416aa8d870fab71030abc9401cfc77b948e8e breaks vhost_net because it always registers the virtio_pci_host_notifier_read() handler function on the ioeventfd, even when vhost_net.ko is using the ioeventfd. The result is both QEMU and vhost_net.ko polling on the same eventfd and the virtio_net.ko guest driver seeing inconsistent results: # ifconfig eth0 192.168.0.1 netmask 255.255.255.0 virtio_net virtio0: output:id 0 is not a head! To fix this, proceed the same as we do for irqfd: add a parameter to virtio_queue_set_host_notifier_fd_handler and in that case only set the notifier, not the handler.
