* block: Add bdrv_co_readv/writev emulationKevin Wolf2011-08-022-8/+76
| | | | | | | | In order to be able to call bdrv_co_readv/writev for drivers that don't implement the functions natively, add an emulation that uses the AIO functions to implement them. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
* block: Emulate AIO functions with bdrv_co_readv/writevKevin Wolf2011-08-021-1/+97
| | | | | | | | Use the bdrv_co_readv/writev callbacks to implement bdrv_aio_readv/writev and bdrv_read/write if a driver provides the coroutine version instead of the synchronous or AIO version. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
* block: Add bdrv_co_readv/writevKevin Wolf2011-08-025-1/+59
| | | | | | | | | Add new block driver callbacks bdrv_co_readv/writev, which work on a QEMUIOVector like bdrv_aio_*, but don't need a callback. The function may only be called inside a coroutine, so a block driver implementing this interface can yield instead of blocking during I/O. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
* coroutine: add test-coroutine --benchmark-lifecycleStefan Hajnoczi2011-08-021-0/+30
| | | | | | | | | | | | | | | | | Add a microbenchmark for coroutine create, enter, and return (aka lifecycle). This is a useful benchmark because users are expected to create many coroutines, one per I/O request for example, and we therefore need to provide good performance in that scenario. To run: make test-coroutine ./test-coroutine --benchmark-lifecycle 20000000 This will do 20,000,000 coroutine create, enter, return iterations and print the resulting time.

* coroutine: add test-coroutine automated testsStefan Hajnoczi2011-08-023-1/+165
| | | | | | | | | | | | | To run automated tests for coroutines: make test-coroutine ./test-coroutine On success the program terminates with exit status 0. On failure an error message is written to stderr and the program exits with exit status 1. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
* coroutine: implement coroutines using gthreadAneesh Kumar K.V2011-08-013-0/+153
| | | | | | | | | | | | | | | | On platforms that don't support makecontext(3) use gthread based coroutine implementation. Darwin has makecontext(3) but getcontext(3) is stubbed out to return ENOTSUP. Andreas Färber <andreas.faerber@web.de> debugged this and contributed the ./configure test which solves the issue for Darwin/ppc64 (and ppc) v10.5. [Original patch by Aneesh, made consistent with coroutine-ucontext.c and switched to GStaticPrivate by Stefan. Tested on Linux and OpenBSD.] Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
* coroutine: introduce coroutinesKevin Wolf2011-08-017-0/+552
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Asynchronous code is becoming very complex. At the same time synchronous code is growing because it is convenient to write. Sometimes duplicate code paths are even added, one synchronous and the other asynchronous. This patch introduces coroutines which allow code that looks synchronous but is asynchronous under the covers. A coroutine has its own stack and is therefore able to preserve state across blocking operations, which traditionally require callback functions and manual marshalling of parameters. Creating and starting a coroutine is easy: coroutine = qemu_coroutine_create(my_coroutine); qemu_coroutine_enter(coroutine, my_data); The coroutine then executes until it returns or yields: void coroutine_fn my_coroutine(void *opaque) { MyData *my_data = opaque; /* do some work */ qemu_coroutine_yield(); /* do some more work */ } Yielding switches control back to the caller of qemu_coroutine_enter(). This is typically used to switch back to the main thread's event loop after issuing an asynchronous I/O request. The request callback will then invoke qemu_coroutine_enter() once more to switch back to the coroutine. Note that if coroutines are used only from threads which hold the global mutex they will never execute concurrently. This makes programming with coroutines easier than with threads. Race conditions cannot occur since only one coroutine may be active at any time. Other coroutines can only run across yield. This coroutines implementation is based on the gtk-vnc implementation written by Anthony Liguori <anthony@codemonkey.ws> but it has been significantly rewritten by Kevin Wolf <kwolf@redhat.com> to use setjmp()/longjmp() instead of the more expensive swapcontext() and by Paolo Bonzini <pbonzini@redhat.com> for Windows Fibers support.

* block/vpc.c: Detect too-large vpc fileSerge E. Hallyn2011-08-011-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | VHD files technically can be up to 2Tb, but virtual pc is limited to 127G. Currently qemu-img refused to create vpc files > 127G, but it is failing to return error when converting from a non-vpc VHD file which is >127G. It returns success, but creates a truncated converted image. Also, qemu-img info claims the vpc file is 127G (and clean). This patch detects a too-large vpc file and returns -EFBIG.

* revamp acpitable parsing and allow to specify complete (headerful) tableMichael Tokarev2011-07-302-127/+178
| | | | | | | | | | | | | | | | | | | | This patch almost rewrites acpi_table_add() function (but still leaves it using old get_param_value() interface). The result is that it's now possible to specify whole table (together with a header) in an external file, instead of just data portion, with a new file= parameter, but at the same time it's still possible to specify header fields as before. Now with the checkpatch.pl formatting fixes, thanks to Stefan Hajnoczi for suggestions, with changes from Isaku Yamahata, and with my further refinements.
