2012-03-13usb: the big renameGerd Hoffmann1-11/+13
Reorganize usb source files. Create a new hw/usb/ directory and move all usb source code to that place. Also make filenames a bit more descriptive. Host adapters are prefixed with "hch-" now, usb device emulations are prefixed with "dev-". Fixup paths Makefile and include paths to make it compile. No code changes.

2012-03-07i8254: Factor out base class for KVM reuseJan Kiszka1-1/+1
Applying the concept used for the *PICs once again: establish a base class for the i8254 that can be used both by the current user space emulation and the upcoming KVM in-kernel version. We share most of the public interface of the i8254, specifically to the pcspk, vmstate, reset and certain init parts.

2012-02-23qemu-ga: add Windows service integrationMichael Roth1-1/+1
This allows qemu-ga to function as a Windows service: - to install the service (will auto-start on boot): qemu-ga --service install - to start the service: net start qemu-ga - to stop the service: net stop qemu-ga - to uninstall service: qemu-ga --service uninstall Original patch by Gal Hammer <ghammer@redhat.com>
2012-02-23qemu-ga: add initial win32 supportMichael Roth1-1/+1
This adds a win32 channel implementation that makes qemu-ga functional on Windows using virtio-serial (unix-listen/isa-serial not currently implemented). Unlike with the posix implementation, we do not use GIOChannel for the following reasons: - glib calls stat() on an fd to check whether S_IFCHR is set, which is the case for virtio-serial on win32. Because of that, a one-time check to determine whether the channel is readable is done by making a call to PeekConsoleInput(), which reports the underlying handle is not a valid console handle, and thus we can never read from the channel. - if one goes as far as to "trick" glib into thinking it is a normal file descripter, the buffering is done in such a way that data written to the output stream will subsequently result in that same data being read back as if it were input, causing an error loop. furthermore, a forced flush of the channel only moves the data into a secondary buffer managed by glib, so there's no way to prevent output from getting read back as input. The implementation here ties into the glib main loop by implementing a custom GSource that continually submits asynchronous/overlapped I/O to fill an GAChannel-managed read buffer, and tells glib to poll the corresponding event handle for a completion whenever there is no data/RPC in the read buffer to notify the main application about.
2012-02-23qemu-ga: fixes for win32 build of qemu-gaMichael Roth1-4/+5
Various stubs and #ifdefs to compile for Windows using mingw cross-build. Still has 1 linker error due to a dependency on the forthcoming win32 versions of the GAChannel/transport class.
2012-02-23qemu-ga: rename guest-agent-commands.c -> commands-posix.cMichael Roth1-1/+1
2012-02-23qemu-ga: separate out common commands from posix-specific onesMichael Roth1-1/+1
Many of the current RPC implementations are very much POSIX-specific and require complete re-writes for Windows. There are however a small set of core guest agent commands that are common to both, and other commands such as guest-file-* which *may* be portable. So we introduce commands.c for the latter, and will rename guest-agent-commands.c to commands-posix.c in a future commit. Windows implementations will go in commands-win32.c, eventually.
2012-02-23qemu-ga: move channel/transport functionality into wrapper classMichael Roth1-0/+1
This is mostly in preparation for the win32 port, which won't use GIO channels for reasons that will be made clearer later. Here the GAChannel class is just a loose wrapper around GIOChannel calls/callbacks, but we also roll in the logic/configuration for various channel types and managing unix socket connections, which makes the abstraction much more complete and further aids in the win32 port since isa-serial/unix-listen will not be supported initially. There's also a bit of refactoring in the main logic to consolidate the exit paths so we can do common cleanup for things like pid files, which weren't always cleaned up previously.

2012-01-17xhci: Initial xHCI implementationHector Martin1-0/+1
Based on the implementation from Hector Martin <hector@marcansoft.com> Hectors's implementation completely sidestepped the qemu usb system and used libusb directly for usb device pass through. So I've ripped out the libusb bits (or left them in disabled, as reference for further coding) and hooked up the qemu subsystem instead. That work is not complete yet though, partly due to limitations of the qemu usb subsystem. Nevertheless I think it is better to continue development in-tree, especially as the qemu usb bits need a bunch of improvements too for decent usb 3.0 support. Current state: - usb-storage emulation should work ok. - Devices which need constant polling (HID emulation like usb-tablet) are known to not work. - ISO xfers are not implemented yet. - superspeed ports are not implemented yet. - usb pass-through is completely untested so far.

This brings a usb audio device to qemu. Output only, fixed at 16bit stereo @ 480000 Hz. Based on a patch from H. Peter Anvin <hpa@linux.intel.com> Usage: add '-device usb-audio' to your qemu command line. Works sorta ok on a idle machine. Known issues: * Is *very* sensitive to latencies. * Burns quite some CPU due to usb polling. In short: It brings the qemu usb emulation to its limits. Enjoy!

2012-01-04vmstate, memory: decouple vmstate from memory APIAvi Kivity1-1/+1
Currently creating a memory region automatically registers it for live migration. This differs from other state (which is enumerated in a VMStateDescription structure) and ties the live migration code into the memory core. Decouple the two by introducing a separate API, vmstate_register_ram(), for registering a RAM block for migration. Currently the same implementation is reused, but later it can be moved into a separate list, and registrations can be moved to VMStateDescription blocks. Signed-off-by: Avi Kivity <avi@redhat.com>
2011-12-22sheepdog: move coroutine send/recv function to generic codePaolo Bonzini1-1/+1
Outside coroutines, avoid busy waiting on EAGAIN by temporarily making the socket blocking. The API of qemu_recvv/qemu_sendv is slightly different from do_readv/do_writev because they do not handle coroutines. It returns the number of bytes written before encountering an EAGAIN.

2011-10-28iSCSI block driverRonnie Sahlberg1-0/+1
This provides built-in support for iSCSI to QEMU. This has the advantage that the iSCSI devices need not be made visible to the host, which is useful if you have very many virtual machines and very many iscsi devices. It also has the benefit that non-root users of QEMU can access iSCSI devices across the network without requiring root privilege on the host. This driver interfaces with the multiplatform posix library for iscsi initiator/client access to iscsi devices hosted at git://github.com/sahlberg/libiscsi.git The patch adds the driver to interface with the iscsi library. It also updated the configure script to * by default, probe is libiscsi is available and if so, build qemu against libiscsi. * --enable-libiscsi Force a build against libiscsi. If libiscsi is not available the build will fail. * --disable-libiscsi Do not link against libiscsi, even if it is available. When linked with libiscsi, qemu gains support to access iscsi resources such as disks and cdrom directly, without having to make the devices visible to the host. You can specify devices using a iscsi url of the form : iscsi://[<username>[:<password>@]]<host>[:<port]/<target-iqn-name>/<lun> When using authentication, the password can optionally be set with LIBISCSI_CHAP_PASSWORD="password" to avoid it showing up in the process list Signed-off-by: Ronnie Sahlberg <ronniesahlberg@gmail.com> Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
