2013-06-06qemu-io: Make cvtnum() a wrapper around strtosz_suffix()Kevin Wolf

2013-06-06qemu-io: Remove unused args_commandKevin Wolf
The original intention seems to be something with handling multiple images at once, but this has never been implemented and the only function ever registered is implemented to make everything behave like a "global" command.

2013-06-05blockdev: reset werror/rerror on drive_delStefan Hajnoczi
Paolo Bonzini <pbonzini@redhat.com> suggested the following test case: 1. Launch a guest and wait at the GRUB boot menu: qemu-system-x86_64 -enable-kvm -m 1024 \ -drive if=none,cache=none,file=test.img,id=foo,werror=stop,rerror=stop -device virtio-blk-pci,drive=foo,id=virtio0,addr=4 2. Hot unplug the device: (qemu) drive_del foo 3. Select the first boot menu entry Without this patch the guest pauses due to ENOMEDIUM. The guest is stuck in a continuous pause loop since the I/O request is retried and fails immediately again when the guest is resumed. With this patch the error is reported to the guest. Note that this scenario actually happens sometimes during libvirt disk hot unplug, where device_del is followed by drive_del. I/O may still be submitted to the drive after drive_del if the guest does not process the PCI hot unplug notification.

2013-06-04block: dump snapshot and image info to specified outputWenchao Xia
bdrv_snapshot_dump() and bdrv_image_info_dump() do not dump to a buffer now, some internal buffers are still used for format control, which have no chance to be truncated. As a result, these two functions have no more issue of truncation, and they can be used by both qemu and qemu-img with correct parameter specified.

2013-06-04block: move qmp and info dump related code to block/qapi.cWenchao Xia
This patch is a pure code move patch, except following modification: 1 get_human_readable_size() is changed to static function. 2 dump_human_image_info() is renamed to bdrv_image_info_dump(). 3 in qmp_query_block() and qmp_query_blockstats, use bdrv_next(bs) instead of direct traverse of global array 'bdrv_states'. 4 collect_snapshots() and collect_image_info() are renamed, unused parameter *fmt in collect_image_info() is removed. 5 code style fix. To avoid conflict and tip better, macro in header file is BLOCK_QAPI_H instead of QAPI_H. Now block.h and snapshot.h are at the same level in include path, block_int.h and qapi.h will both include them.

2013-06-04block: drop bs_snapshots global variableStefan Hajnoczi
The bs_snapshots global variable points to the BlockDriverState which will be used to save vmstate. This is really a savevm.c concept but was moved into block.c:bdrv_snapshots() when it became clear that hotplug could result in a dangling pointer. While auditing the block layer's global state I came upon bs_snapshots and realized that a variable is not necessary here. Simply find the first BlockDriverState capable of internal snapshots each time this is needed. The behavior of bdrv_snapshots() is preserved across hotplug because new drives are always appended to the bdrv_states list. This means that calling the new find_vmstate_bs() function is idempotent - it returns the same BlockDriverState unless it was hot-unplugged.

2013-06-04qemu-iotests: make compare_images() commonStefan Hajnoczi
The iotests.compare_images() function returns True if two image files have the identical data.

2013-06-04block: add block driver read only whitelistFam Zheng
We may want to include a driver in the whitelist for read only tasks such as diagnosing or exporting guest data (with libguestfs as a good example). This patch introduces a readonly whitelist option, and for backward compatibility, the old configure option --block-drv-whitelist is now an alias to rw whitelist. Drivers in readonly list is only permitted to open file readonly, and returns -ENOTSUP for RW opening. E.g. To include vmdk readonly, and others read+write: ./configure --target-list=x86_64-softmmu \ --block-drv-rw-whitelist=qcow2,raw,file,qed \ --block-drv-ro-whitelist=vmdk Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2013-06-03xilinx_spips: Fix QSPI FIFO sizePeter Crosthwaite
QSPI has a bigger FIFO than the regular SPI controller. Differentiate between the two with correct FIFO sizes for each. This is the first piece of class data for SPIPS, so this patch sees the creation of the XilinxSPIPSClass definition and assoicated QOM constructs.

2013-06-03xilinx_spips: seperate SPI and QSPI as two classesPeter Crosthwaite
Make SPI and QSPI different classes. QSPIPS is setup as a child of SPIPS. Only QSPI has the LQSPI functionality, so move all that to the child class.

2013-06-03xen: remove xen_vcpu_initStefano Stabellini
No need for xen_vcpu_init anymore: - the RTC emulator doesn't have any periodic timers continuously running even in absence of guest interactions anymore; - qemu_dummy_start_vcpu takes care of disabling TCG for us, so we don't need to do it manually here.
