2009-08-03enable NPTL for ppc-linux-user targets in configureNathan Froyd1-0/+2
Enabling support for ppc64-linux-user should be easy enough to do later. Signed-off-by: Nathan Froyd <froydnj@codesourcery.com> Signed-off-by: malc <av1474@comtv.ru>
2009-08-03linux-user: handle POWERPC_EXCP_STCXNathan Froyd1-0/+68
We handle conditional stores as an exception so we can ensure that no other thread is changing memory out from underneath us. Signed-off-by: Nathan Froyd <froydnj@codesourcery.com> Signed-off-by: malc <av1474@comtv.ru>

2009-08-03target-ppc: retain l{w,d}arx loaded valueNathan Froyd5-10/+17
We do this so we can check on the corresponding stc{w,d}x. whether the value has changed. It's a poor man's form of implementing atomic operations and is valid only for NPTL usermode Linux emulation. Signed-off-by: Nathan Froyd <froydnj@codesourcery.com> Signed-off-by: malc <av1474@comtv.ru>

If translation block is interrupted by e.g. mmu exception we need to compute conditional flags for inclusion into saved cpu state. Otherwise after return from trap conditional instructions would use stale psr/xcc data. Signed-off-by: igor.v.kovalenko@gmail.com -- Kind regards, Igor V. Kovalenko

2009-07-30e1000.c doesn't properly emulate EERD and ICS registersBill Paul1-4/+9
Once again, the emulation of the EERD and ICS registers in e1000.c is incorrect. Nobody has noticed this before because none of the Intel-written e1000 drivers use these registers, and all of the independently written open source drivers copy Intel's example, so they don't use them either. Regardless, these registers are documented in the programmer's manuals, and their emulated behavior doesn't match the verified behavior of real hardware, so any software that does use them doesn't function correctly. -Bill Signed-off-by: Bill Paul <wpaul@windriver.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-30qemu-option: fix parse_option_number().Gerd Hoffmann1-0/+1
It works much better when parse_option_number actually returns the number parsed ... Common breakage resulting from this bug is that 'qemu -hda foo.img -cdrom bar.iso' stops working (cdrom isn't there).

2009-07-30Fix VM state change handlers running out of orderMarkus Armbruster3-9/+54
When a VM state change handler changes VM state, other VM state change handlers can see the state transitions out of order. bmdma_map(), scsi_disk_init() and virtio_blk_init() install VM state change handlers to restart DMA. These handlers can vm_stop() by running into a write error on a drive with werror=stop. This throws the VM state change handler callback into disarray. Here's an example case I observed: 0. The virtual IDE drive goes south. All future writes return errors. 1. Something encounters a write error, and duly stops the VM with vm_stop(). 2. vm_stop() calls vm_state_notify(0). 3. vm_state_notify() runs the callbacks in list vm_change_state_head. It contains ide_dma_restart_cb() installed by bmdma_map(). It also contains audio_vm_change_state_handler() installed by audio_init(). 4. audio_vm_change_state_handler() stops audio stuff. 5. User continues VM with monitor command "c". This runs vm_start(). 6. vm_start() calls vm_state_notify(1). 7. vm_state_notify() runs the callbacks in vm_change_state_head. 8. ide_dma_restart_cb() happens to come first. It does its work, runs into a write error, and duly stops the VM with vm_stop(). 9. vm_stop() runs vm_state_notify(0). 10. vm_state_notify() runs the callbacks in vm_change_state_head. 11. audio_vm_change_state_handler() stops audio stuff. Which isn't running. 12. vm_stop() finishes, ide_dma_restart_cb() finishes, step 7's vm_state_notify() resumes running handlers. 13. audio_vm_change_state_handler() starts audio stuff. Oopsie. Fix this by moving the actual write from each VM state change handler into a new bottom half (suggested by Gleb Natapov).

2009-07-30vnc: fix copyrect screen corruptionGerd Hoffmann1-0/+22
When sending a copyrect command to the vnc client, we must also update the local server surface. Otherwise the server's and the client's idea of the screen content run out of sync and screen updates don't work correctly. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-30Remove the virtio-{blk, console}-pci-0-10 device typesMark McLoughlin1-46/+11
These are now unused. However, perhaps the idea is that when we add -device, they will be useful? In that case, we should add virtio-net-pci-0-10 too. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-07-30fix migration to obey -SPaolo Bonzini4-2/+7
Since migration returns right away, starting the VM right after calling qemu_start_incoming_migration is wrong even if -S is not passed. We have to do this after migration has completed.

2009-07-30alsa: add host suspend/resume supportBjørn Mork1-2/+47
Both input and output streams may be in SND_PCM_STATE_SUSPENDED after the host is suspended and resumed, meaning "Hardware is suspended". snd_pcm_readi() and snd_pcm_writei() will return -ESTRPIPE if called while the stream is in this state. Call snd_pcm_resume() to enable audio output and capture after host resume. Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: malc <av1474@comtv.ru>
