2009-10-15qcow2: Bring synchronous read/write back to lifeKevin Wolf
When the synchronous read and write functions were dropped, they were replaced by generic emulation functions. Unfortunately, these emulation functions don't provide the same semantics as the original functions did. The original bdrv_read would mean that we read some data synchronously and that we won't be interrupted during this read. The latter assumption is no longer true with the emulation function which needs to use qemu_aio_poll and therefore allows the callback of any other concurrent AIO request to be run during the read. Which in turn means that (meta)data read earlier could have changed and be invalid now. qcow2 is not prepared to work in this way and it's just scary how many places there are where other requests could run. I'm not sure yet where exactly it breaks, but you'll see breakage with virtio on qcow2 with a backing file. Providing synchronous functions again fixes the problem for me.

2009-10-15Documentation: Add missing tags to placeholdersKevin Wolf
Not all placeholders in options descriptions had the @var tag on them. Add the tag so that it's clearly visible that they are placeholders. Patchworks-ID: 35602 Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-15Documentation: Highlight placeholders in suboptionsKevin Wolf
Currently, suboptions (i.e. something like file=file for -drive) are rendered as @code, so we're losing any @var highlighting in the man pages. Replace them by @option, so that you actually can see what is a placeholder and what is meant verbatim.

2009-10-15net: fix multiple NICs causing net opts process to stopMark McLoughlin
For NICs, net_init_client() returns the index into the NICInfo table. qemu_opts_foreach() interprets non-zero as an error return an stops iterating over the options. So, if you have more than one '-net nic' on the command line, subsequent '-net' options do not get processed. Fix this by making net_client_init() only return non-zero if net_init_client() returns an error.

2009-10-15net: refactor packet queueing codeMark McLoughlin
The packet queue code is fairly standalone, has some complex details and easily reusable. It makes sense to split it out on its own. This patch doesn't contain any functional changes.

2009-10-15net: allow NICs to be connected to netdevsMark McLoughlin
Introduce a 'peer' member to VLANClientState as an alternative to a vlan. The idea being that packets are transfered directly from peer clients rather than going through a vlan.

2009-10-15net: maintain a list of vlan-less clientsMark McLoughlin

2009-10-15net: allow clients not associated with a vlanMark McLoughlin
Allow net clients to be created which are not connected to any vlan. This is needed by Gerd in order to allow adding -device nic, where the absence of a vlan parameter will not imply vlan=0. Also needed to allow adding a -netdevice option which doesn't connect the backend to a vlan.

2009-10-15net: remove id field from NICInfoMark McLoughlin
Just use the name field instead since we now use the id paramater as the name, if supplied. Only implication with this change is that if id is not supplied, the value of the name paramater is used as an id.

2009-10-15eepro100: Remove unused device status entriesStefan Weil
Once upon the time when QEMU hacking was fun there was a brave knight who wanted to have a driver for a special intel nic. So he started by cloning ne2000.c which also meant that the new born eepro100.c was immediately three years old. Other knights who also wanted to have fun and take their part in the battle thought that it would be a good idea to remove stupid code which says "missing nic load, missing nic save". They saved everything they saw, man and women, ne2000 code and runtime address offsets, and put all saved elements in a prison called vm data. When the first knight came back and noticed the unhappy prisoners, he wanted to set them free. But the keepers of the keys told him that they would have to stay there forever for compatibility reasons. So our brave knight now takes a new effort to save the souls of the poor prisoners by removing their names. Their bodies will have to rot in the dungeons of compatibility forever, watched by the keepers of the keys.

The SCSI-2 documentation suggests, that although the block descriptor is optional for an arbitrary SCSI-2 device (chapter 8.2.10, http://ldkelley.com/SCSI2/SCSI2/SCSI2/SCSI2/SCSI2-08.html ) it is mandatory for a disk: chapters 9.1.2, 9.3.3 ( http://ldkelley.com/SCSI2/SCSI2/SCSI2/SCSI2-09.html ) don't say "optional" any more, just "The block descriptor in the MODE SENSE data describes the block lengths that are used on the medium." v2: limit the number of sectors reported in the block descriptor to 24 bits.

See e.g. https://bugzilla.redhat.com/495964 https://bugzilla.redhat.com/519540 https://bugzilla.redhat.com/496627 The pulseaudio backend seems to work well, so we should allow it to be selected as the default.

2009-10-12Fixed wacom emulationFrançois Revol
- for absolute mode, scale coordinates to the real device maximum values, since some drivers (on Haiku and Linux at least) need them as such, and the HID descriptor is boggus on some models anyway, - keep the coordinates even when no button is pressed, on real tablet the pen is sensed on the surface even without direct contact, and drivers expect this, - map left button to pressure according to what the Haiku driver wants, - map the right button to the pen button, - map the middle button to the eraser, - use asynchronous reporting as the hid code does, stops the Haiku driver (and probably others) from spending 50% cpu polling for changes.

2009-10-12rom loader: fix sparc -kernel boot.Gerd Hoffmann
Changes: (1) register pstrcpy_targphys() in rom list, it is used for kernel command lines by a number of architectures. (2) add rom_ptr() function to get a pointer for applying changes to loaded images. Needed for example to tell the linux kernel where it finds the initrd image by updating the header. (3) make sparc use rom_ptr for initrd setup. booting sparc-test works now, and 'info roms' shows this: (qemu) info roms addr=0000000000000000 size=0x2a3828 mem=ram name="phdr #0: vmlinux-2.6.11+tcx" addr=00000000007ff000 size=0x00000e mem=ram name="cmdline" addr=0000000000800000 size=0x400000 mem=ram name="/root/qemu-test/sparc-test/linux.img" addr=0000000070000000 size=0x0e4000 mem=rom name="phdr #0: /home/kraxel/projects/qemu/build-zfull/pc-bios/openbios-sparc32" reboot via 'system_reset' works too.
