2014-07-01qemu-img create: add 'nocow' optionChunyan Liu
Add 'nocow' option so that users could have a chance to set NOCOW flag to newly created files. It's useful on btrfs file system to enhance performance. Btrfs has low performance when hosting VM images, even more when the guest in those VM are also using btrfs as file system. One way to mitigate this bad performance is to turn off COW attributes on VM files. Generally, there are two ways to turn off NOCOW on btrfs: a) by mounting fs with nodatacow, then all newly created files will be NOCOW. b) per file. Add the NOCOW file attribute. It could only be done to empty or new files. This patch tries the second way, according to the option, it could add NOCOW per file. For most block drivers, since the create file step is in raw-posix.c, so we can do setting NOCOW flag ioctl in raw-posix.c only. But there are some exceptions, like block/vpc.c and block/vdi.c, they are creating file by calling qemu_open directly. For them, do the same setting NOCOW flag ioctl work in them separately.

2014-07-01virtio-blk: remove need for explicit x-data-plane=on optionStefan Hajnoczi
The x-data-plane=on|off option is no longer useful because the iothread=<iothread> option conveys the same information plus which IOThread to use. Do not delete x-data-plane=on|off yet as a convenience to people using this legacy experimental option. We will drop it in QEMU 2.2. Instead, turn on data-plane when either x-data-plane=on or iothread=<iothread> are used. The following command-line uses data-plane: qemu -device virtio-blk-pci,iothread=foo,drive=drive0 Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2014-07-01virtio-blk: replace x-iothread with iothread link propertyStefan Hajnoczi
Up until now -device virtio-blk-pci,x-iothread=<id> was used to assign an IOThread. This was a temporary solution while we cleaned up QOM link properties. This patch switches over to a QOM link property since it is now possible to restrict the setter to unrealized instances and automatically unref the IOThread when the virtio-blk-pci device is freed. Since the "iothread" property is a QOM property and not a qdev property, we must alias it explicitly for virtio-blk-pci, as well as CCW and s390-virtio.

2014-07-01virtio: fix virtio-blk child refcount in transportsStefan Hajnoczi
object_initialize() leaves the object with a refcount of 1. object_property_add_child() adds its own reference which is dropped again when the property is deleted. The upshot of this is that we always have a refcount >= 1. Upon hot unplug the virtio-blk child is not finalized! Drop our reference after the child property has been added to the parent.

2014-07-01virtio-blk: use aliases instead of duplicate qdev propertiesStefan Hajnoczi
virtio-blk-pci, virtio-blk-s390, and virtio-blk-ccw all duplicate the qdev properties of their VirtIOBlock child. This approach does not work well with string or pointer properties since we must be careful about leaking or double-freeing them. Use the QOM alias property to forward property accesses to the VirtIOBlock child. This way no duplication is necessary. Remember to stop calling virtio_blk_set_conf() so that we don't clobber the values already set on the VirtIOBlock instance.

Move the x-data-plane property. Originally it was outside since not every transport may wish to support dataplane.

2014-07-01virtio-blk: avoid qdev property definition duplicationStefan Hajnoczi
It becomes unwiedly to duplicate all virtio-blk qdev property definitions due to an #ifdef. The C preprocessor syntax makes it a little hard to resolve this cleanly but we can extract the #ifdef and call a macro it defines later. Avoiding duplication is important since it will only get worse when we move the x-data-plane qdev property here too. We'd have a combinatorial explosion since x-data-plane has its own #ifdef.

2014-06-30vfio: Make BARs native endianAlexey Kardashevskiy
Slow BAR access path is used when VFIO fails to mmap() BAR. Since this is just a transport between the guest and a device, there is no need to do endianness swapping. This changes BARs to use native endianness. Since non-ROM BARs were doing byte swapping, we need to remove it so does the patch. As the result, this eliminates cancelling byte swaps and there is no change in behavior for non-ROM BARs. ROM BARs were declared little endian too but byte swapping was not implemented for them so they never actually worked on big endian systems as there was no cancelling byte swap. This fixes endiannes for ROM BARs by declaring them native endian and only fixing access sizes as it is done for non-ROM BARs.

2014-06-30vfio-pci: Fix MSI-X masking performanceAlex Williamson
There are still old guests out there that over-exercise MSI-X masking. The current code completely sets-up and tears-down an MSI-X vector on the "use" and "release" callbacks. While this is functional, it can slow an old guest to a crawl. We can easily skip the KVM parts of this so that we keep the MSI route and irqfd setup. We do however need to switch VFIO to trigger a different eventfd while masked. Actually, we have the option of continuing to use -1 to disable the trigger, but by using another EventNotifier we can allow the MSI-X core to emulate pending bits and re-fire the vector once unmasked. MSI code gets updated as well to use the same setup and teardown structures and functions. Prior to this change, an igbvf assigned to a RHEL5 guest gets about 20Mbps and 50 transactions/s with netperf (remote or VF->PF). With this change, we get line rate and 3k transactions/s remote or 2Gbps and 6k+ transactions/s to the PF. No significant change is expected for newer guests with more well behaved MSI-X support.

2014-06-30serial: poll the serial console with G_IO_HUPRoger Pau Monne
On FreeBSD polling a master pty while the other end is not connected with G_IO_OUT only results in an endless wait. This is different from the Linux behaviour, that returns immediately. In order to demonstrate this, I have the following example code: http://xenbits.xen.org/people/royger/test_poll.c When executed on Linux: $ ./test_poll In callback On FreeBSD instead, the callback never gets called: $ ./test_poll So, in order to workaround this, poll the source with G_IO_HUP (which makes the code behave the same way on both Linux and FreeBSD).
