2009-08-10qdev/prop: add drive property.Gerd Hoffmann
Adds a (host) drive property, intended to be used by virtual disk backend drivers. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Message-Id:
2009-08-10add -drive if=noneGerd Hoffmann
This adds a host drive, but doesn't implicitly add a guest drive for it. First step in splitting host and guest configuration, check the following patches to see how this can be used ...

2009-08-10QemuOpts: switch over -device.Gerd Hoffmann
Make -device switch use the QemuOpts framework. Everything should continue to work like it did before. New: "-set device.$id.$property=$value" works. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Message-Id:
2009-08-10QemuOpts: add -set optionGerd Hoffmann
One use case will be file for drives (no filename quoting issues), i.e. -drive id=test,if=virtio -set drive.test.file=/vmdisk/test-virtio.img It will work for any other option (assuming handled by QemuOpts) though. Except for id= for obvious reasons ;). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Message-Id:

2009-08-10QemuOpts: qemu_opts_parse: fix id= parsingGerd Hoffmann
We can't use get_param_value(), it can't handle parameters without '=' in there.

2009-08-10Fix symfind.Laurent Desnogues
this patch fixes an issue in symfind. Assume you have the following symbols: Address Size 0045bca0 00000080 T s0 0045bd20 00000112 T s1 You'll notice that s1 is s0 + size. So the current symfind will find that address 0045bd20 belongs to s0 instead of s1.

2009-08-04Sparc64: replace tsptr with helper routineIgor Kovalenko
tl and tsptr of members sparc64 cpu state must be changed simultaneously to keep trap state window in sync with current trap level. Currently translation of store to tl does not change tsptr, which leads to corrupt trap state on corresponding trap level. This patch removes tsptr from sparc64 cpu state and replaces all uses with call to helper routine. Changes v0->v1: - reimplemented helper routine with tcg generator - on cpu reset trap type and pstate are populated with power-on reset values, including tl=maxtl Signed-off-by: igor.v.kovalenko@gmail.com Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-07-30e1000.c doesn't properly emulate EERD and ICS registersBill Paul
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 Hoffmann
It works much better when parse_option_number actually returns the number parsed ...

2009-07-30Fix VM state change handlers running out of orderMarkus Armbruster
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).
