2008-11-02tcg-ops.h: _i64 TCG immediate instructions cleanupaurel32
Move addi_i64, muli_i64 and subi_i64 out of #if TCG_TARGET_REG_BITS as both implementations are strictly identical. Use the same optimisation (ie when imm == 0) for addi_i64 and subi_64 than the 32-bit version.

2008-10-31Increase default IO timeout from 10ms to 5saliguori
With the recent changes to the main loop, we no longer have unconditional polling. This means we can now sleep in select() for much longer than we previously did. This patch increases our select() sleep time from 10ms to 5s which is effectively unlimited since we're going to wake up sooner than that in almost all circumstances. With this patch, I see the number of wake-ups with an idle dynamic ticks guest drop from 80 per second to about 15 times per second.

2008-10-31Implement "info chardev" command. (Gerd Hoffmann)aliguori
This patch makes qemu keep track of the character devices in use and implements a "info chardev" monitor command to print a list. qemu_chr_open() sticks the devices into a linked list now. It got a new argument (label), so there is a name for each device. It also assigns a filename to each character device. By default it just copyes the filename passed in. Individual drivers can fill in something else though. qemu_chr_open_pty() sets the filename to name of the pseudo tty allocated. Output looks like this: (qemu) info chardev monitor: filename=unix:/tmp/run.sh-26827/monitor,server,nowait serial0: filename=unix:/tmp/run.sh-26827/console,server serial1: filename=pty:/dev/pts/5 parallel0: filename=vc:640x480 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5575 c046a42c-6fe2-441c-8c8c-71466251a162
2008-10-31fix bdrv_aio_read API breakage in qcow2 (Andrea Arcangeli)aliguori
I noticed the qemu_aio_flush was doing nothing at all. And a flood of cmd_writeb commands leading to a noop-invocation of qemu_aio_flush were executed. In short all 'memset;goto redo' places must be fixed to use the bh and not to call the callback in the context of bdrv_aio_read or the bdrv_aio_read model falls apart. Reading from qcow2 holes is possible with phyisical readahead (kind of breada in linux buffer cache). This is needed at least for scsi, ide is lucky (or it has been band-aided against this API breakage by fixing the symptom and not the real bug). Same bug exists in qcow of course, can be fixed later as it's less urgent.

2008-10-31Make DMA bottom-half driven (v2)aliguori
The current DMA routines are driven by a call in main_loop_wait() after every select. This patch converts the DMA code to be driven by a constantly rescheduled bottom half. The advantage of using a scheduled bottom half is that we can stop scheduling the bottom half when there no DMA channels are runnable. This means we can potentially detect this case and sleep longer in the main loop. The only two architectures implementing DMA_run() are cris and i386. For cris, I converted it to a simple repeating bottom half. I've only compile tested this as cris does not seem to work on a 64-bit host. It should be functionally identical to the previous implementation so I expect it to work. For x86, I've made sure to only fire the DMA bottom half if there is a DMA channel that is runnable. The effect of this is that unless you're using sb16 or a floppy disk, the DMA bottom half never fires. You probably should test this malc. My own benchmarks actually show slight improvement by it's possible the change in timing could affect your demos. Since v1, I've changed the code to use a BH instead of a timer. cris at least seems to depend on faster than 10ms polling.

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.
