2009-07-10qcow1: Fix qcow_aio_writevKevin Wolf
Pass is_write = 1 to qcow_aio_setup when writing. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-10Prefer sysfs for USB host devicesMark McLoughlin
Scanning for devices via /sys/bus/usb/devices/ and using them via the /dev/bus/usb/<bus>/<device> character devices is the prefered method on modern kernels, so try that first. When using SELinux and libvirt, qemu will have access to /sys/bus/usb but not /proc/bus/usb, so although the current code will work just fine, it will generate SELinux AVC warnings.

2009-07-10usb-ohci: Fix endianness issueMichael Buesch
This fixes a possible endianness issue in the usb-ohci hw module. hcca.frame and ohci->frame_number are 16bit, so use cpu_to_le16(). Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-07-10qemu-io: fix memory leakKevin Wolf
qemu-io leaks the request buffer whenever the read or write function isn't executed completely down the "normal" code path. [hch: also fix the aio and vectored variants the same way] Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
2009-07-10qemu-io: add flag to mark files growableChristoph Hellwig
Add a -g flag to the open command and the main qemu-io command line to allow opening a file growable. This is only allowed for protocols, mirroring the limitation exposed through bdrv_file_open. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Kevin Wolf <kwolf@redhat.com>
2009-07-10qemu-io: better input validation for vector-based commandsChristoph Hellwig
Fix up a couple of issues with validating the input of the various length arguments for the vectored I/O commands: - do the alignment check on each length instead the always 0 count argument - use a long long varibale for the cvtnum return value so that we can check wether it wasn't a number - check for a too large argument instead of truncating it Also refactor it into a common helper for all four calers and avoid parsing the numbers twice.

2009-07-09Allow setting qemu process name v2Andi Kleen
Set the Linux process name to the name argument specified with name. I find this useful to see which guests are taking CPU time in top. This doesn't affect ps, which checks argv[0], but rewriting the environment uses much more code, so I only used this simple way. v2: Use separate process= argument, no prefixes.

2009-07-09configure: Append extra cflags and ldflagsJan Kiszka
In order to allow overriding flags that are set by configure, we have to append them instead of prepending as it is done so far. v2: Clarify documentation. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

Otherwise if you hot remove an eepro100 NIC and then migrate, you get: Unknown savevm section or instance 'eeprom' 0 on the destination side. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-09Don't leak VLANClientState on PCI hot removeMark McLoughlin
destroy_nic() requires that NICInfo::private by a PCIDevice pointer, but then goes on to require that the same pointer matches VLANClientState::opaque. That is no longer the case for virtio-net since qdev and wasn't previously the case for rtl8139, ne2k_pci or eepro100. Make the situation a lot more clear by maintaining a VLANClientState pointer in NICInfo. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-09Don't abort if TUNSETSNDBUF fails where no sndbuf= arg is suppliedMark McLoughlin

The performance of qcow2 has improved meanwhile, so we don't need to special-case it any more. Switch the default to write-through caching like all other block drivers. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-09net: set a default value for sndbuf=Mark McLoughlin
On reflection, perhaps it does make sense to set a default value for the sndbuf= tap parameter. For best effect, sndbuf= should be set to just below the capacity of the physical NIC. Setting it higher will cause packets to be dropped before the limit is hit. Setting it much lower will not cause any problems unless you set it low enough such that the guest cannot queue up new packets before the NIC has emptied its queue. In Linux, txqueuelen=1000 by default for ethernet NICs. Given a 1500 byte MTU, 1Mb is a good choice for sndbuf. If it turns out that txqueuelen is actually much lower than this, then sndbuf is essentially disabled. In the event that txqueuelen is much higher, it's unlikely that the NIC will be able to empty a 1Mb queue. Thanks to Herbert Xu for this logic.

2009-07-09qdev/pci: misc fixes.Gerd Hoffmann
* fix secondary bus setup. * use base->name instead of "FIXME" for device name. Yes, the device name is redundant. Only for drivers converted to qdev already though. Once all drivers are converted we can and should kill it. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2009-07-09qdev: remove DeviceTypeGerd Hoffmann
The only purpose DeviceType serves is creating a linked list of DeviceInfo structs. This removes DeviceType and add a next field to DeviceInfo instead, so the DeviceInfo structs can be changed that way. Elimitates a pointless extra level of indirection. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2009-07-09qdev: replace bus_type enum with bus_info struct.Gerd Hoffmann
BusInfo is filled with name and size (pretty much like I did for DeviceInfo as well). There is also a function pointer to print bus-specific device information to the monitor. sysbus is hooked up there, I've also added a print function for PCI. Device creation is slightly modified as well: The device type search loop now also checks the bus type while scanning the list instead of complaining thereafter in case of a mismatch. This effectively gives each bus a private namespace for device names. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Paul Brook <paul@codesourcery.com>
2009-07-09qdev: update pci device registration.Gerd Hoffmann
Makes pci_qdev_register take a PCIDeviceInfo struct instead of a bunch of parameters. Also adds config_read and config_write callbacks to PCIDeviceInfo, so drivers needing these can be converted to the qdev device API too. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
