2017-02-28fsdev: add IO throttle support to fsdev devicesPradeep Jagadeesh
This patchset adds the throttle support for the 9p-local driver. For now this functionality can be enabled only through qemu cli options. QMP interface and support to other drivers need further extensions. To make it simple for other 9p drivers, the throttle code has been put in separate files.

2017-02-24tcg: add options for enabling MTTCGKONRAD Frederic
We know there will be cases where MTTCG won't work until additional work is done in the front/back ends to support. It will however be useful to be able to turn it on. As a result MTTCG will default to off unless the combination is supported. However the user can turn it on for the sake of testing.

2017-02-21hw/i386: Deprecate -drive if=scsi with PC machine typesMarkus Armbruster
The PC machines (pc-q35-* pc-i440fx-* pc-* isapc xenfv) automatically create lsi53c895a SCSI HBAs and SCSI devices to honor -drive if=scsi. For giggles, try -drive if=scsi,bus=25,media=cdrom --- this makes QEMU create 25 of them. lsi53c895a is thoroughly obsolete (PCI Ultra2 SCSI, ca. 2000), and currently has no maintainer in QEMU. megasas is a better choice, except with old OSes that lack drivers. virtio-scsi is a much better choice when you have a driver, but only (newish) Linux comes with one in the box. There is no good default that works for all guests. Encourage users to pick a non-obsolete SCSI HBA that works for them by deprecating -drive if=scsi.

2017-02-09ui: refactor code for populating SocketAddress from vnc_display_openDaniel P. Berrange
The code which interprets the CLI args to populate the SocketAddress objects for plain & websockets VNC is quite complex already and will need further enhancements shortly. Refactor it into separate methods to avoid vnc_display_open getting even larger. As a side effect of the refactoring, it is now possible to specify a listen address for the websocket server explicitly. e.g, -vnc localhost:5900,websockets=0.0.0.0:8080 will listen on localhost for the plain VNC server, but expose the websockets VNC server on the public interface. This refactoring also removes the restriction that prevents enabling websockets when the plain VNC server is listening on a UNIX socket.

2016-11-14block/curl: Drop TFTP "support"Max Reitz
Because TFTP does not support byte ranges, it was never usable with our curl block driver. Since apparently nobody has ever complained loudly enough for someone to take care of the issue until now, it seems reasonable to assume that nobody has ever actually used it. Therefore, it should be safe to just drop it from curl's protocol list. [Jeff Cody: Below is additional summary pulled, with some rewording, from followup emails between Max and Markus, to explain what worked and what didn't] TFTP would sometimes work, to a limited extent, for images <= the curl "readahead" size, so long as reads started at offset zero. By default, that readahead size is 256KB. Reads starting at a non-zero offset would also have returned data from a zero offset. It can become more complicated still, with mixed reads at zero offset and non-zero offsets, due to data buffering. In short, TFTP could only have worked before in very specific scenarios with unrealistic expectations and constraints.

2016-06-16vl.c: Add '-L help' which lists data dirs.Richard W.M. Jones
QEMU compiles a list of data directories from various sources. When consuming a QEMU binary it's useful to be able to get this list of data directories: a primary reason is so you can list what BIOSes or keymaps ship with this version of QEMU. However without reproducing the method that QEMU uses internally, it's not possible to get the list of data directories. This commit adds a simple '-L help' option that just lists out the data directories as qemu calculates them: $ ./x86_64-softmmu/qemu-system-x86_64 -L help /home/rjones/d/qemu/pc-bios /usr/local/share/qemu $ ./x86_64-softmmu/qemu-system-x86_64 -L /tmp -L help /tmp /home/rjones/d/qemu/pc-bios /usr/local/share/qemu Signed-off-by: Richard W.M.

2016-04-19fw_cfg: Adopt /opt/RFQDN conventionMarkus Armbruster
FW CFG's primary user is QEMU, which uses it to expose configuration information (in the widest sense) to Firmware. Thus the name FW CFG. FW CFG can also be used by others for their own purposes. QEMU is merely acting as transport then. Names starting with opt/ are reserved for such uses. There is no provision, however, to guide safe sharing among different such users. Fix that, loosely following QMP precedence: names should start with opt/RFQDN/, where RFQDN is a reverse fully qualified domain name you control. Based on a more ambitious patch from Michael Tsirkin.
