* NBD: Use qemu_socket functions to open TCP and UNIX socketsNick Thomas2011-04-071-2/+2
| | | | | | | | | | | | | | | | | | This commit has the side-effect of making the qemu-nbd binary capable of binding to IPv6 addresses. ("-b ::1", for instance). block/nbd.c fails to parse IPv6 IP addresses correctly at this point, but will work over IPv6 when given a hostname. It still works over IPv4 as before. We move the qemu-sockets object from the 'common' to the 'block' list in the Makefile. The common list includes the block list, so this is effectively a no-op for the rest of the code. We also add 32-bit 'magic' attributes to nbd_(request|reply) to facilitate calculating maximum request/response sizes later.

And we change the client to send it's own Init message regardless of receiving this one. Additional Init messages will be regarded as acceptable, the first one received after connection establishment is the determining one wrt capabilities.

* | qcow2: Add QcowCacheKevin Wolf2011-01-241-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | This adds some new cache functions to qcow2 which can be used for caching refcount blocks and L2 tables. When used with cache=writethrough they work like the old caching code which is spread all over qcow2, so for this case we have merely a cleanup. The interesting case is with writeback caching (this includes cache=none) where data isn't written to disk immediately but only kept in cache initially. This leads to some form of metadata write batching which avoids the current "write to refcount block, flush, write to L2 table" pattern for each single request when a lot of cluster allocations happen. Instead, cache entries are only written out if its required to maintain the right order. In the pure cluster allocation case this means that all metadata updates for requests are done in memory initially and on sync, first the refcount blocks are written to disk, then fsync, then L2 tables. This improves performance of scenarios with lots of cluster allocations noticably (e.g. installation or after taking a snapshot). Signed-off-by: Kevin Wolf <kwolf@redhat.com>
* usb: data structs and helpers for usb descriptors.Gerd Hoffmann2011-01-111-1/+1
| | | | | | | | | | | | | | | | This patch adds hw/usb-desc.[ch] files. They carry data structures for various usb descriptors and helper functions to generate usb packets from the structures. The intention is to have a internal representation of the device desription which is more usable than the current char array blobs, so we can have common code handle common usb device emulation using the device description. The usage of this infrastructure is optional for usb drivers as there are cases such as pass-through where it probably isn't very useful. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

| | | | | | | | | | | | | This patch implements the read/write state machine. Operations are fully asynchronous and multiple operations may be active at any time. Allocating writes lock tables to ensure metadata updates do not interfere with each other. If two allocating writes need to update the same L2 table they will run sequentially.

| | | | | | | | | | | | | | This patch adds code to look up data cluster offsets in the image via the L1/L2 tables. The L2 tables are writethrough cached in memory for performance (each read/write requires a lookup so it is essential to cache the tables).

This backend builds a little differently from the other tracing backends. Specifically there is no 'trace.c' file, because the 'dtrace' command line tool generates a '.o' file directly from the dtrace probe definition file. The probe definition is usually named with a '.d' extension but QEMU uses '.d' files for its external makefile dependancy tracking, so this uses '.dtrace' as the extension for the probe definition file. The 'tracetool' program gains the ability to generate a trace.h file for DTrace, and also to generate the trace.d file containing the dtrace probe definition.

The probe definition is usually named with a '.d' extension but QEMU uses '.d' files for its external makefile dependancy tracking, so this uses '.dtrace' as the extension for the probe definition file. The 'tracetool' program gains the ability to generate a trace.h file for DTrace, and also to generate the trace.d file containing the dtrace probe definition. Example usage of a dtrace probe in systemtap looks like: probe process("qemu").mark("qemu_malloc") { printf("Malloc %d %p\n", $arg1, $arg2); } * .gitignore: Ignore trace-dtrace.* * Makefile: Extra rules for generating DTrace files * Makefile.obj: Don't build trace.o for DTrace, use trace-dtrace.o generated by 'dtrace' instead * tracetool: Support for generating DTrace data files Signed-off-by: Daniel P.

| * spice: add audioGerd Hoffmann2010-11-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the spice audio interface. With this patch applied audio can be forwarded over the network from/to the spice client. Both recording and playback is supported. The driver is first in the driver list, but the can_be_default flag is set only in case spice is active. So if you have the spice protocol enabled the spice audio driver is the default one, otherwise whatever comes first after spice in the list. Overriding the default using QEMU_AUDIO_DRV works in any case.
