2011-04-07qemu-img: Initial progress printing supportJes Sorensen5-5/+132
This adds the basic infrastructure for supporting progress output on the command line, as well as progress support for qemu-img commands 'rebase' and 'convert'.

2011-04-07block: Do not cache device size for removable mediaStefan Hajnoczi1-8/+6
The block layer caches the device size to avoid doing lseek(fd, 0, SEEK_END) every time this value is needed. For removable media the device size becomes stale if a new medium is inserted. This patch simply prevents device size caching for removable media. A smarter solution is to update the cached device size when a new medium is inserted. Given that there are currently bugs with CD-ROM media change I do not want to implement that approach until we've gotten things correct first.

2011-04-07Do not delete BlockDriverState when deleting the driveRyan Harper3-20/+20
When removing a drive from the host-side via drive_del we currently have the following path: drive_del qemu_aio_flush() bdrv_close() // zaps bs->drv, which makes any subsequent I/O get // dropped. Works as designed drive_uninit() bdrv_delete() // frees the bs. Since the device is still connected to // bs, any subsequent I/O is a use-after-free. The value of bs->drv becomes unpredictable on free. As long as it remains null, I/O still gets dropped, however it could become non-null at any point after the free resulting SEGVs or other QEMU state corruption. To resolve this issue as simply as possible, we can chose to not actually delete the BlockDriverState pointer. Since bdrv_close() handles setting the drv pointer to NULL, we just need to remove the BlockDriverState from the QLIST that is used to enumerate the block devices. This is currently handled within bdrv_delete, so move this into its own function, bdrv_make_anon(). The result is that we can now invoke drive_del, this closes the file descriptors and sets BlockDriverState->drv to NULL which prevents futher IO to the device, and since we do not free BlockDriverState, we don't have to worry about the copy retained in the block devices. We also don't attempt to remove the qdev property since we are no longer deleting the BlockDriverState on drives with associated drives. This also allows for removing Drives with no devices associated either.

2011-04-04cpu-all.h: Remove unnecessary target-specific ifdef for CPU_QuadUPeter Maydell1-3/+2
CPU_QuadU isn't used on all targets, but there's no harm in defining the typedef anyway. It only needs to be guarded by CONFIG_SOFTFLOAT, because softfloat-native doesn't have a float128 type. This avoids the need for every new target which uses CPU_QuadU to add itself to an #ifdef in what ought to be target-agnostic code.
