2016-11-14block/curl: Drop TFTP "support"Max Reitz1-3/+3
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. Jones1-0/+2
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 Armbruster1-5/+19
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.

2016-03-24input-linux: switch over to -objectGerd Hoffmann1-9/+0
This patches makes input-linux use -object instead of a new command line switch. So, instead of the switch ... -input-linux /dev/input/event$nr ... you must create an object this way: -object input-linux,id=$name,evdev=/dev/input/event$nr Bonus is that you can hot-add and hot-remove them via monitor now.

2016-03-22qemu-log: new option -dfilter to limit outputAlex Bennée1-0/+18
When debugging big programs or system emulation sometimes you want both the verbosity of cpu,exec et all but don't want to generate lots of logs for unneeded stuff. This patch adds a new option -dfilter which allows you to specify interesting address ranges in the form: -dfilter 0x8000..0x8fff,0xffffffc000080000+0x200,... Then logging code can use the new qemu_log_in_addr_range() function to decide if it will output logging information for the given range.

2016-03-08input: linux evdev supportGerd Hoffmann1-0/+9
This patch adds support for reading input events directly from linux evdev devices and forward them to the guest. Unlike virtio-input-host which simply passes on all events to the guest without looking at them this will interpret the events and feed them into the qemu input subsystem. Therefore this is limited to what the qemu input subsystem and the emulated input devices are able to handle. Also there is no support for absolute coordinates (tablet/touchscreen). So we are talking here about basic mouse and keyboard support. The advantage is that it'll work without virtio-input drivers in the guest, the events are delivered to the usual ps/2 or usb input devices (depending on what the machine happens to have). And for keyboards qemu is able to switch the keyboard between guest and host on hotkey. The hotkey is hard-coded for now (both control keys), initialy the guest owns the keyboard. Probably most useful when assigning vga devices with vfio and using a physical monitor instead of vnc/spice/gtk as guest display. Usage: Add '-input-linux /dev/input/event<nr>' to the qemu command line. Note that udev has rules which populate /dev/input/by-{id,path} with static names, which might be more convinient to use.

With this property, users can control if this filter is 'on' or 'off'. The default behavior for filter is 'on'.

2016-02-28migration: allow machine to enforce configuration section migrationGreg Kurz1-1/+2
Migration of pseries-2.3 doesn't have configuration section. Unfortunately, QEMU 2.4/2.4.1/2.5 are buggy and always stream and expect the configuration section, and break migration both ways. This patch introduces a property which allows to enforce a configuration section for machines who don't have one. It can be set at startup: -machine enforce-config-section=on or later from the QEMU monitor: qom-set /machine enforce-config-section on It is up to the tooling to set or unset this property according to the version of the QEMU at the other end of the pipe.

2016-02-23spice: add opengl/virgl/dmabuf supportGerd Hoffmann1-0/+4
This adds support for dma-buf passing to spice. This makes virtio-gpu with 3d acceleration work with spice. Workflow: * virglrenderer renders the guest command stream into a texture. * qemu exports the texture as dma-buf and passes on that dma-buf to spice-server. * spice-server passes the dma-buf to spice-client, using unix socket file descriptor passing. * spice-client asks the window systems composer to render the dma-buf to the screen. Requires cutting edge spice (server) and spice-gtk (client) builds, from git master branch. Also requires libvirt managing your qemu instance, and using "virt-viewer --attach $guest". libvirt will connect spice-server and spice-client using unix sockets instead of tcp sockets then, which is required for file descriptor passing. Works for the local case (spice server and client on the same machine) only. Supporting remote too is planned (by feeding the dma-bufs into gpu-assisted video encoder), but not there yet. gl mode is turned off by default, use "-spice gl=on,$otherargs" to enable it.

The Microsoft spec about the SLIC and MSDM ACPI tables at <http://go.microsoft.com/fwlink/p/?LinkId=234834> requires the OEM ID and OEM Table ID fields to be consistent between the SLIC and the RSDT/XSDT. That further affects the FADT, because a similar match between the FADT and the RSDT/XSDT is required by the ACPI spec in general. This patch wires up the previous three patches. Cc: "Michael S.
