2010-12-27x86: Filter out garbage from segment flags dumpJan Kiszka1-2/+2
Only bits 8..23 of the segment flags contain valid data, so only dump those when printing the CPU state. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-12-27Fix migrate set speed doc argLuiz Capitulino1-1/+1
We used to ignore any fractional part in 0.13, but due to recent changes (started with 9f9b17a4f0865286391e4d3a0a735230122a2289) migrate_set_speed will reject the fractional part. We don't expect existing clients to be relying on this, but we need to update the documentation to reflect the change.

2010-12-18win32: Fix CRLF problem in make_device_config.shStefan Weil1-1/+1
QEMU source code with CRLF line endings which is quite common on windows hosts fails with current make_device_config.sh. The awk script gets the name of the included file with \r, so instead of pci.mak it will search for pci.mak\r which of course does not work. Fix this by removing any \r. v2: Avoid using sub() and \r with awk because they are unsupported on some platforms. Use tr to remove \r.

2010-12-17qed: Consistency check supportStefan Hajnoczi3-3/+336
This patch adds support for the qemu-img check command. It also introduces a dirty bit in the qed header to mark modified images as needing a check. This bit is cleared when the image file is closed cleanly. If an image file is opened and it has the dirty bit set, a consistency check will run and try to fix corrupted table offsets. These corruptions may occur if there is power loss while an allocating write is performed. Once the image is fixed it opens as normal again.

2010-12-17qed: Read/write supportStefan Hajnoczi4-2/+663
This patch implements the read/write state machine. Operations are fully asynchronous and multiple operations may be active at any time. Allocating writes lock tables to ensure metadata updates do not interfere with each other. If two allocating writes need to update the same L2 table they will run sequentially. If two allocating writes need to update different L2 tables they will run in parallel. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-12-17qed: Table, L2 cache, and cluster functionsStefan Hajnoczi8-2/+866
This patch adds code to look up data cluster offsets in the image via the L1/L2 tables. The L2 tables are writethrough cached in memory for performance (each read/write requires a lookup so it is essential to cache the tables). With cluster lookup code in place it is possible to implement bdrv_is_allocated() to query the number of contiguous allocated/unallocated clusters.
