2013-02-26qemu-log: default to stderr for logging outputPeter Maydell
Switch the default for qemu_log logging output from "/tmp/qemu.log" to stderr. This is an incompatible change in some sense, but logging is mostly used for debugging purposes so it shouldn't affect production use. The previous behaviour can be obtained by adding "-D /tmp/qemu.log" to the command line. This change requires us to: * update all the documentation/help text (we take the opportunity to smooth out minor inconsistencies between the phrasing in linux-user/bsd-user/system help messages) * make linux-user and bsd-user defer to qemu-log for the default logging destination rather than overriding it themselves * ensure that all logfile closing is done via qemu_log_close() and that that function doesn't close stderr as well as the obvious change to the behaviour of do_qemu_set_log() when no logfile name has been specified.

2013-02-06qemu-char: Saner naming of memchar stuff & doc fixesMarkus Armbruster
New device, has never been released, so we can still improve things without worrying about compatibility. Naming is a mess. The code calls the device driver CirMemCharDriver, the public API calls it "memory", "memchardev", or "memchar", and the special commands are named like "memchar-FOO". "memory" is a particularly unfortunate choice, because there's another character device driver called MemoryDriver. Moreover, the device's distinctive property is that it's a ring buffer, not that's in memory. Therefore: * Rename CirMemCharDriver to RingBufCharDriver, and call the thing a "ringbuf" in the API. * Rename QMP and HMP commands from memchar-FOO to ringbuf-FOO. * Rename device parameter from maxcapacity to size (simple words are good for you). * Clearly mark the parameter as optional in documentation. * Fix error reporting so that chardev-add reports to current monitor, not stderr. * Replace cirmem in C identifiers by ringbuf. * Rework documentation. Document the impact of our crappy UTF-8 handling on reading. * QMP examples that even work. I could split this up into multiple commits, but they'd change the same documentation lines multiple times. Not worth it. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2013-01-21vnc: added initial websocket protocol supportTim Hardeck
This patch adds basic Websocket Protocol version 13 - RFC 6455 - support to QEMU VNC. Binary encoding support on the client side is mandatory. Because of the GnuTLS requirement the Websockets implementation is optional (--enable-vnc-ws). To activate Websocket support the VNC option "websocket"is used, for example "-vnc :0,websocket". The listen port for Websocket connections is (5700 + display) so if QEMU VNC is started with :0 the Websocket port would be 5700. As an alternative the Websocket port could be manually specified by using ",websocket=<port>" instead. Parts of the implementation base on Anthony Liguori's QEMU Websocket patch from 2010 and on Joel Martin's LibVNC Websocket implementation.

2012-10-24qemu-config: Add new -add-fd command line optionCorey Bryant
This option can be used for passing file descriptors on the command line. It mirrors the existing add-fd QMP command which allows an fd to be passed to QEMU via SCM_RIGHTS and added to an fd set. This can be combined with commands such as -drive to link file descriptors in an fd set to a drive: qemu-kvm -add-fd fd=3,set=2,opaque="rdwr:/path/to/file" -add-fd fd=4,set=2,opaque="rdonly:/path/to/file" -drive file=/dev/fdset/2,index=0,media=disk This example adds dups of fds 3 and 4, and the accompanying opaque strings to the fd set with ID=2. qemu_open() already knows how to handle a filename of this format. qemu_open() searches the corresponding fd set for an fd and when it finds a match, QEMU goes on to use a dup of that fd just like it would have used an fd that it opened itself.

Added an option to let qemu transfer a configuration file to bios, "etc/boot-fail-wait", which could be specified by command -boot reboot-timeout=T T have a max value of 0xffff, unit is ms. With this option, guest will wait for a given time if not find bootabled device, then reboot. If reboot-timeout is '-1', guest will not reboot, qemu passes '-1' to bios by default. This feature need the new seabios's support. Seabios pulls the value from the fwcfg "file" interface, this interface is used because SeaBIOS needs a reliable way of obtaining a name, value size, and value.

This patch provides a way to optionally suppress spurious interrupts, as a workaround for systems described below: Some old operating systems do not handle spurious interrupts well, and qemu tends to generate them significantly more often than real hardware. Examples: - Microport UNIX System V/386 v 2.1 (ca 1987) (The main problem I'm fixing: Without this patch, it panics sporadically when accessing the hard disk.) - AT&T UNIX System V/386 Release 4.0 Version 2.1a (ca 1991) See screenshot in "QEMU Official OS Support List": http://www.claunia.com/qemu/objectManager.php?sClass=application&iId=9 (I don't have this system to test.) - A report about OS/2 boot lockup from 2004 by Hampa Hug: http://lists.nongnu.org/archive/html/qemu-devel/2004-09/msg00367.html (My patch was partially inspired by his.)

2012-08-24vga: add some optional CGA compatibility hacksMatthew Ogilvie
This patch adds some optional compatibility hacks (default disabled) to allow Microport UNIX to function under qemu. I've tried to structure it to be easy to add more hacks for other old CGA programs, if anyone ever needs them. Microport UNIX System V/386 v 2.1 (ca 1987) tries to program the CGA registers directly with neither the assistance of BIOS, nor with proper handling of EGA/VGA-only registers. Note that it didn't work on real VGA hardware, either (although in that case, the most obvious problems seemed to be out-of-range hsync and/or vsync signalling, rather than the issues in this patch). Eventually real MDA and/or CGA support might provide an alternative to this patch, although a hybrid approach like this patch might still be useful in marginal cases.
