2010-04-26kvm: allow qemu to set EPT identity mapping addressSheng Yang
If we use larger BIOS image than current 256KB, we would need move reserved TSS and EPT identity mapping pages. Currently TSS support this, but not EPT. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>

2010-04-25Remove IO_MEM_SUBWIDTH.Richard Henderson
Greatly simplify the subpage implementation by not supporting multiple devices at the same address at different widths. We don't need full copies of mem_read/mem_write/opaque for each address, only a single index back into the main io_mem_* arrays.

2010-04-25linux-user: Remove ELFLOAD32.Richard Henderson
The ABI-specific types used by linux_binprm and image_info are different after forcing TARGET_ABI32 on. Which means that the parameters that load_elf_binary_multi sees are not those that loader_exec passed. This is inherently broken and is more trouble than it's worth fixing.

2010-04-23target-sparc: Fix address masking in ldqf and stqf.Richard Henderson
Use address_mask on both addr and addr+8 in both these routines, rather than explicit masking with 0xffffffff.

2010-04-23block: Free iovec arrays allocated by multiwrite_merge()Stefan Hajnoczi
A new iovec array is allocated when creating a merged write request. This patch ensures that the iovec array is deleted in addition to its qiov owner.

2010-04-23qemu-img: Fix BRDV_O_FLAGS typoStefan Hajnoczi
It should be BDRV_O_FLAGS instead of BRDV_O_FLAGS. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-04-23qemu-img: Eliminate bdrv_new_open() code duplicationStefan Hajnoczi
Several commands have code to create a BlockDriverState and open a file. The bdrv_new_open() function can be used to perform these steps. This patch converts the qemu-img commands to actually use bdrv_new_open(). Replaced the bdrv_new_open() 'readonly' argument with bdrv_open()-style flags to support generic flags like BDRV_O_NO_BACKING.

2010-04-23block: Do not export bdrv_firstStefan Hajnoczi
The bdrv_first linked list of BlockDriverStates is currently extern so that block migration can iterate the list. However, since there is already a bdrv_iterate() function there is no need to expose bdrv_first.

2010-04-23block: split raw_getlengthChristoph Hellwig
Split up the raw_getlength into separate generic, solaris and BSD versions to reduce the ifdef maze a bit. The BSD variant still is a complete maze, but to clean it up properly we'd need some people using the BSD variants to figure out what code is used for what variant.

2010-04-23block: get rid of the BDRV_O_FILE flagChristoph Hellwig
BDRV_O_FILE is only used to communicate between bdrv_file_open and bdrv_open. It affects two things: first bdrv_open only searches for protocols using find_protocol instead of all image formats and host drivers. We can easily move that to the caller and pass the found driver to bdrv_open. Second it is used to not force a read-write open of a snapshot file. But we never use bdrv_file_open to open snapshots and this behaviour doesn't make sense to start with. qemu-io abused the BDRV_O_FILE for it's growable option, switch it to using bdrv_file_open to make sure we only open files as growable were we can actually support that. This patch requires Kevin's "[PATCH] Replace calls of old bdrv_open" to be applied first. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-04-23Replace calls of old bdrv_openKevin Wolf
What is known today as bdrv_open2 becomes the new bdrv_open. All remaining callers of the old function are converted to the new one. In some places they even know the right format, so they should have used bdrv_open2 from the beginning. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-04-23qcow2: Fix creation of large imagesKevin Wolf
qcow_create2 assumes that the new image will only need one cluster for its refcount table initially. Obviously that's not true any more when the image is big enough (exact value depends on the cluster size). This patch calculates the refcount table size dynamically. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-04-23qcow2: Trigger blkdebug eventsKevin Wolf
This adds blkdebug events to qcow2 to allow injecting I/O errors in specific places. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
