2009-08-27e1000.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>
2009-08-27Fix 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).

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>

2009-08-25target-mips: fix conditional moves off fp condition codesNathan Froyd1-5/+5
Conditional moves off fp condition codes were using the result of get_fp_bit to isolate and test the relevant condition code. However, get_fp_bit returns the bit number of the condition code, not a bitmask. (Compare the use of get_fp_bit in gen_compute_branch1, for instance.) Fixed by shifting a bitmask into place using the result of get_fp_bit in the relevant functions (gen_mov{ci,cf_s,cf_d,cf_ps}).

2009-07-29Add a pc-0.11 machine type and make the pc type an aliasMark McLoughlin1-1/+2
The pc-0.11 type allows users of qemu-0.11 to use a machine type which they know will remain compatible when the upgrade to qemu-0.12. Management tools may choose to canonicalize the 'pc' machine type to 'pc-0.11' so that if the 'pc' alias changes target in future versions of qemu, the machine type used will remain compatible.

2009-07-29Add machine type aliasesMark McLoughlin2-0/+6
Add an 'alias' field to QEMUMachine and display it in the output of 'qemu -M ?' with an '(aliased to foo)' suffix. Aliases can change targets in newer versions of qemu, so management tools may choose canonicalize machine types to ensure that if a user chooses an alias, that the actual machine type used will remain compatible in future. This is intended to mimic a symlink to a machine description file. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-29Add support for fd=name to tap and socket networkingMark McLoughlin1-7/+35
This allows a program to initialize a host networking device using a file descriptor passed over a unix monitor socket. The program must first pass the file descriptor using SCM_RIGHTS ancillary data with the getfd monitor command. It then may do "host_net_add tap fd=name" to use the named file descriptor.

2009-07-29Add getfd and closefd monitor commandsMark McLoughlin2-0/+87
Add monitor commands to support passing file descriptors via SCM_RIGHTS. getfd assigns the passed file descriptor a name for use with other monitor commands. closefd allows passed file descriptors to be closed. If a monitor command actually uses a named file descriptor, closefd will not be required. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-29Add SCM_RIGHTS support to unix socket character devicesMark McLoughlin2-1/+56
If a file descriptor is passed via a message with SCM_RIGHTS ancillary data on a unix socket, store the file descriptor for use in the chr_read() handler. Close the file descriptor if it was not used. The qemu_chr_get_msgfd() API provides access to the passed descriptor.

While fixing migration with -S, commit 89befdd1a6b18215153b8976682d57b7d03d5782 broke the rest of us. Poor glommer, with a poor family, spare him his life from this monstruosity.

2009-07-29slirp: Use monotonic clock if available (v2)Ed Swierk3-32/+2

2009-07-29HPET fixes for reg writesBeth Kon2-13/+8
This patch addresses the problems found by Andriy Gapon: - The code was incorrectly overwriting the high order 32 bits of the timer and hpet config registers. This didn't show up in testing because linux and windows use hpet in legacy mode, where the high order 32 bits (advertising available interrupts) of the timer config register are ignored, and the high order 32 bits of the hpet config register are reserved and unused. - The mask for level-triggered interrupts was off by a bit. (hpet doesn't currently support level-triggered interrupts). In addition, I removed some unused #defines, and corrected the ioapic interrupt values advertised. I'd set this up early in hpet development and never went back to correct it, and no bugs resulted since linux and windows use hpet in legacy mode where available interrupts are ignored.

Instead of storing the backing file in its own BlockDriverState, VMDK uses the BlockDriverState of the raw image file it opened.
