I have a guest OS which sends the command 0xfd to the keyboard controller during initialization. To get rid of the message "qemu: unsupported keyboard cmd=0x%02x\n" I added support for the pulse output bit commands. I found the following explanation here: http://www.win.tue.nl/~aeb/linux/kbd/scancodes-11.html#ss11.3 Command 0xf0-0xff: Pulse output bit Bits 3-0 of the output port P2 of the keyboard controller may be pulsed low for approximately 6 µseconds. Bits 3-0 of this command specify the output port bits to be pulsed. 0: Bit should be pulsed. 1: Bit should not be modified. The only useful version of this command is Command 0xfe. (For MCA, replace 3-0 by 1-0 in the above.) Command 0xfe: System reset Pulse bit 0 of the output port P2 of the keyboard controller. This will reset the CPU.

QEMUFileBuffered stops writing when the underlying QEMUFile is not ready, and tells its producer so. However, when the underlying QEMUFile becomes ready, it neglects to pass that information along, resulting in stoppage of all data until the next tick (a tenths of a second). Usually this doesn't matter, because most QEMUFiles used with QEMUFileBuffered are almost always ready, but in the case of exec: migration this is not true, due to the small pipe buffers used to connect to the target process. The result is very slow migration. Fix by detecting the readiness notification and propagating it. The detection is a little ugly since QEMUFile overloads put_buffer() to send it, but that's the suject for a different patch.

According to scc_escc_um.pdf: - Reset Highest IUS must update irq status to allow processing of the next priority interrupt. - rx interrupt has always higher priority than tx on same channel The documentation only explicitly says that Reset Highest IUS command (0x38) clears IUS bits, not that it clears the corresponding interrupt too, so don't clear interrupts on this command.

configure adds the macro WIN32_LEAN_AND_MEAN to QEMU_CFLAGS, and SDL_syswm.h defines it, too. This results in a compiler warning (redefinition of WIN32_LEAN_AND_MEAN in SDL_syswm.h. That warning prevents compilations for win32 with warning = error). Fix this by removing the definition of WIN32_LEAN_AND_MEAN before including SDL_syswm.h.

The reason for not actually canceling the I/O is because with virtualization and lots of VM running, a guest fs may mistake a overload of the host, as an IDE timeout. So rather than canceling the I/O, it's safer to wait I/O completion and simulate that the I/O has completed just before the io cancellation was requested by the guest. This way if ntfs or an app writes data without checking for -EIO retval, and it thinks the write has succeeded, it's less likely to run into troubles. Similar issues for reads. Furthermore because the DMA operation is splitted into many synchronous aio_read/write if there's more than one entry in the SG table, without this patch the DMA would be cancelled in the middle, something we've no idea if it happens on real hardware too or not. Overall this seems a great risk for zero gain. This approach is sure safer than previous code given we can't pretend all guest fs code out there to check for errors and reply the DMA if it was completed partially, given a timeout would never materialize on a real harddisk unless there are defective blocks (and defective blocks are practically only an issue for reads never for writes in any recent hardware as writing to blocks is the way to fix them) or the harddisk breaks as a whole.

bdrv_eject() gets called when a device model opens or closes the tray. If the block driver implements method bdrv_eject(), that method gets called. Drivers host_cdrom implements it, and it opens and closes the physical tray, and nothing else. When a device model opens, then closes the tray, media changes only if the user actively changes the physical media while the tray is open. This is matches how physical hardware behaves. If the block driver doesn't implement method bdrv_eject(), we do something quite different: opening the tray severs the connection to the image by calling bdrv_close(), and closing the tray does nothing. When the device model opens, then closes the tray, media is gone, unless the user actively inserts another one while the tray is open, with a suitable change command in the monitor. This isn't how physical hardware behaves. Rather inconvenient when programs "helpfully" eject media to give you a chance to change it. The way bdrv_eject() behaves here turns that chance into a must, which is not what these programs or their users expect. Change the default action not to call bdrv_close(). Instead, note the tray status in new BlockDriverState member tray_open. Use it in bdrv_is_inserted(). Arguably, the device models should keep track of tray status themselves. But this is less invasive. Signed-off-by: NMarkus Armbruster <armbru@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

This patch improves the resilience of the load_vmstate() function, doing further and better ordered tests. In load_vmstate(), if there is any error on bdrv_snapshot_goto(), except if the error is on VM state device, load_vmstate() will return zero and the VM will be started with major corruption chances. The current process: - test if there is any writable device without snapshot support - if exists return -error - get the device that saves the VM state, possible return -error but unlikely because it was tested earlier - flush I/O - run bdrv_snapshot_goto() on devices - if fails, give an warning and goes to the next (not good!) - if fails on the VM state device, return zero (not good!) - check if the requested snapshot exists on the device that saves the VM state and the state is not zero - if fails return -error - open the file with the VM state - if fails return -error - load the VM state - if fails return -error - return zero New behavior: - get the device that saves the VM state - if fails return -error - check if the requested snapshot exists on the device that saves the VM state and the state is not zero - if fails return -error - test if there is any writable device without snapshot support - if exists return -error - test if the devices with snapshot support have the requested snapshot - if anyone fails, return -error - flush I/O - run snapshot_goto() on devices - if anyone fails, return -error - open the file with the VM state - if fails return -error - load the VM state - if fails return -error - return zero do_loadvm must not call vm_start if any error has occurred in load_vmstate.
