Reset is now triggered after init, no need for explicit calls anymore. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-05-28doc: Update monitor info subcommandsStefan Hajnoczi
The "info blockstats" documentation was copy-pasted as "info block" instead of "info blockstats". The documentation for "commands", "jit", "numa", "qdm", and "roms" is missing. This patch resolves these issues in qemu-monitor.hx. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-05-28Fix overflow in i440fx_init()Avi Kivity
The ram_size parameter can be larger than an int, so it may be truncated. Fix by using the correct type. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-05-28block: Add missing bdrv_delete() for SG_IO BlockDriver in find_image_format()Nicholas A. Bellinger
This patch adds a missing bdrv_delete() call in find_image_format() so that a SG_IO BlockDriver properly releases the temporary BlockDriverState *bs created from bdrv_file_open() Signed-off-by: Nicholas A. Bellinger <nab@linux-iscsi.org> Reported-by: Chris Krumme <chris.krumme@windriver.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-05-28qcow2: Fix corruption after error in update_refcountKevin Wolf
After it is done with updating refcounts in the cache, update_refcount writes all changed entries to disk. If a refcount block allocation fails, however, there was no change yet and therefore first_index = last_index = -1. Don't treat -1 as a normal sector index (resulting in a 512 byte write!) but return without updating anything in this case. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-05-28qcow2: Fix corruption after refblock allocationKevin Wolf
Refblock allocation code needs to take into consideration that update_refcount will load a different refcount block into the cache, so it must initialize the cache for a new refcount block only afterwards. Not doing this means that not only the refcount in the wrong block is updated, but also that the caller will work on the wrong block. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-05-28qcow2: Return right error code in write_refcount_block_entriesKevin Wolf
write_refcount_block_entries used to return -EIO for any errors. Change this to return the real error code. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-05-28qcow2: Change l2_load to return 0/-errnoKevin Wolf
Provide the error code to the caller instead of just indicating success/error. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-05-28qcow2: Allow qcow2_get_cluster_offset to return errorsKevin Wolf
qcow2_get_cluster_offset() looks up a given virtual disk offset and returns the offset of the corresponding cluster in the image file. Errors (e.g. L2 table can't be read) are currenctly indicated by a return value of 0, which is unfortuately the same as for any unallocated cluster. So in effect we can't check for errors. This makes the old return value a by-reference parameter and returns the usual 0/-errno error code. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-05-28block.h: Make BDRV_SECTOR_SIZE 64 bit safeJes Sorensen
C defaults to int, so make definition of BDRV_SECTOR_SIZE 64 bit safe as it and BDRV_SECTOR_MASK may be used against 64 bit addresses. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-05-28posix-aio-compat: Expand tabs that have crept inStefan Hajnoczi
This patch expands tabs on a few lines so the code formats nicely and follows the QEMU coding style. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-05-28drive: allow rerror, werror and readonly for if=noneGerd Hoffmann
When creating guest disks the qdev way using ... -drive if=none,id=$name,args -device $driver,drive=$name it is not possible to specify rerror, werror and readonly arguments for drive as drive_init allows/blocks them based on the interface (if=) specified and none isn't white-listed there. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-05-28add support for protocol driver create_optionsMORITA Kazutaka
This patch enables protocol drivers to use their create options which are not supported by the format. For example, protcol drivers can use a backing_file option with raw format. Signed-off-by: MORITA Kazutaka <morita.kazutaka@lab.ntt.co.jp> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-05-28qemu-io: Add multiwrite commandKevin Wolf
The new multiwrite commands allows to use qemu-io for testing bdrv_aio_multiwrite. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-05-28block: Fix multiwrite with overlapping requestsKevin Wolf
With overlapping requests, the total number of sectors is smaller than the sum of the nb_sectors of both requests. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-05-28qcow2: Fix error handling in l2_allocateKevin Wolf
l2_allocate has some intermediate states in which the image is inconsistent. Change the order to write to the L1 table only after the new L2 table has successfully been initialized. Also reset the L2 cache in failure case, it's very likely wrong. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-05-28qcow2: Clear L2 table cache after write errorKevin Wolf
If the L2 table was already updated in cache, but writing it to disk has failed, we must not continue using the changed version in the cache to stay consistent with what's on the disk. Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2010-05-27Make cache=unsafe the default for -snapshotAlexander Graf
When using -snapshot we don't care about data integrity of the cow file at all, so let's disable flushing there and squeeze out the last drop of performance we could possibly get. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-05-26Add cache=unsafe parameter to -driveAlexander Graf
Usually the guest can tell the host to flush data to disk. In some cases we don't want to flush though, but try to keep everything in cache. So let's add a new cache value to -drive that allows us to set the cache policy to most aggressive, disabling flushes. We call this mode "unsafe", as guest data is not guaranteed to survive host crashes anymore. This patch also adds a noop function for aio, so we can do nothing in AIO fashion.

2010-05-24Fix error handling in qemu_read_config_fileKevin Wolf

2010-05-24sdl: Do not disable screensaver by defaultJan Kiszka

2010-05-22sparc64: flush translations on mmu context changeIgor V. Kovalenko

2010-05-22Fix tarbin Makefile ruleStuart Brady
The 'tarbin' Makefile rule doesn't include qemu-system-sparc64, but should do, now that sparc64-softmmu is in the default target list. The rule attempts to tar up binaries that were not built if a target list was passed to the configure script -- in which case, it will either fail, or otherwise include binaries from previous builds. Fix both problems once and for all by building a list of binaries to include in the tarball, using the list of targets to be built.

2010-05-22Put dependency files in proper subdirJan Kiszka
This seems to resolve subtle breakages of our build system: Dependency files generated for targets like 'dir/foo.o' were saved as 'foo.d'. Now, if there was also a target 'foo.o', one of the dependency file was overwritten. Concrete example: libhw*/macio.o vs. libhw*/ide/macio.o. And this often left a segfaulting build result behind when changing the "wrong" data structures". Fix it by generating proper 'dir/foo.d'.
