2008-12-04Introduce fls() helperaliguori
This is needed for virtio. The implementation is originally from Marcelo Tosatti. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5868 c046a42c-6fe2-441c-8c8c-71466251a162

when compiling on NetBSD: warning: array subscript has type 'char' Signed-off-by: Christoph Egger <Christoph.Egger@amd.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5727 c046a42c-6fe2-441c-8c8c-71466251a162
2008-11-12Include <strings.h> for ffs().balrog
ffs() is in <strings.h> although bsd compatible systems have it in <string.h> already. ffs() is used in omap1.c, omap2.c, omap_i2c.c, bt-sdp.c. These uses can be replaced with clz32() but ffs is more available. Problem was spotted by malc. Make host-utils.h formatting more consistent. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5708 c046a42c-6fe2-441c-8c8c-71466251a162
2008-11-11sockets: helper functions for qemu (Gerd Hoffman)aliguori
This patch creates a new source file qemu-sockets.c with a bunch of helper functions to create listening and connected sockets. New features of this code are (a) support for searching for a free port in a given range and (b) support for IPv6. The following patches put that code into use.

2008-11-09Add qemu_strndup: qemu_strdup with length limit.balrog
Also optimise qemu_strdup by using memcpy - using pstrcpy is usually suboptimal. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5653 c046a42c-6fe2-441c-8c8c-71466251a162
2008-11-08Revert r5532, r5536 and a piece of r5531.balrog
The use of strncat and strndup was correct, pstrcpy and pstrdup wasn't. I'll try to restore building on non-gnu OSes in a later commit. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5651 c046a42c-6fe2-441c-8c8c-71466251a162

2008-10-31Make bottom halves more robustaliguori
Bottom halves are supposed to not complete until the next iteration of the main loop. This is very important to ensure that guests can not cause stack overflows in the block driver code. Right now, if you attempt to schedule a bottom half within a bottom half callback, you will enter an infinite loop. This patch uses the same logic that we use for the IOHandler loop to make the bottom half processing robust in list manipulation while in a callback. This patch also introduces idle scheduling for bottom halves. qemu_bh_poll() returns an indication of whether any bottom halves were successfully executed. qemu_aio_wait() uses this to immediately return if a bottom half was executed instead of waiting for a completion notification. qemu_bh_schedule_idle() works around this by not reporting the callback has run in the qemu_bh_poll loop. qemu_aio_wait() probably needs some refactoring but that would require a larger code audit. idle scheduling seems like a good compromise.

2008-10-08Fix IO performance regression in sparcaliguori
Replace signalfd with signal handler/pipe. There is no way to interrupt the CPU execution loop when a file descriptor becomes readable. This results in a large performance regression in sparc emulation during bootup. This patch switches us to signal handler/pipe which was originally suggested by Ian Jackson. The signal handler lets us interrupt the CPU emulation loop while the write to a pipe lets us avoid the select/signal race condition.
