* 9pfs: use coroutine_fn annotation in hw/9pfs/co*.[ch]Greg Kurz2016-10-171-7/+10
| | | | | | | | | All these functions use the v9fs_co_run_in_worker() macro, and thus always call qemu_coroutine_self() and qemu_coroutine_yield(). Let's mark them to make it obvious they execute in coroutine context. Signed-off-by: Greg Kurz <groug@kaod.org>
* 9p: switch back to readdir()Greg Kurz2016-06-061-4/+6
| | | | | | | | | | This patch changes the 9p code to use readdir() again instead of readdir_r(), which is deprecated in glibc 2.24. All the locking was put in place by a previous patch. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Greg Kurz <gkurz@linux.vnet.ibm.com>
* 9p/fsdev: remove obsolete references to virtioGreg Kurz2016-06-061-2/+1Star
| | | | | | | | | | Most of the 9p code is now virtio agnostic. This patch does a final cleanup: - drop references to Virtio from the header comments - fix includes Also drop a couple of leading empty lines while here. Signed-off-by: Greg Kurz <gkurz@linux.vnet.ibm.com>
* 9pfs: Clean up includesPeter Maydell2016-01-291-0/+1
| | | | | | | | | | Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes.

* 9pfs: rename virtio-9p-coth.{c,h} to coth.{c,h}Wei Liu2016-01-081-1/+1
| | | | | | | | | | | Those two files are not virtio specific. Rename them to use generic names. Fix includes in various C files. Change define guards and comments in header files. Signed-off-by: Wei Liu <wei.liu2@citrix.com> Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
* coroutine: move into libqemuutil.a libraryDaniel P. Berrange2015-10-201-1/+1
| | | | | | | | | | | | | | | | | The coroutine files are currently referenced by the block-obj-y variable. The coroutine functionality though is already used by more than just the block code. eg migration code uses coroutine yield. In the future the I/O channel code will also use the coroutine yield functionality. Since the coroutine code is nicely self-contained it can be easily built as part of the libqemuutil.a library, making it widely available. The headers are also moved into include/qemu, instead of the include/block directory, since they are now part of the util codebase, and the impl was never in the block/ directory either.

* hw/9pfs: Abstract open state of fid to V9fsFidOpenStateAneesh Kumar K.V2011-10-311-8/+8
| | | | | | | | To implement synthetic file system in Qemu we may not really require file descriptor and Dir *. Make generic code use V9fsFidOpenState instead. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>

* hw/9pfs: Add fs driver specific details to fscontextAneesh Kumar K.V2011-09-221-4/+4
| | | | | | | | Add a new context flag PATHNAME_FSCONTEXT and indicate whether the fs driver track fid using path names. Also add a private pointer that help us to track fs driver specific values in there Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
* hw/9pfs: Move fid pathname tracking to seperate data type.Aneesh Kumar K.V2011-09-221-9/+11
| | | | | | | This enables us to add handles to track fids later. The V9fsPath added is similar to V9fsString except that the size include the NULL byte also. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
