Some are called do_COMMAND() (old ones, usually), some hmp_COMMAND(), and sometimes COMMAND pointlessly differs in spelling. Normalize to hmp_COMMAND(), where COMMAND is exactly the command name with '-' replaced by '_'. Exceptions: * do_device_add() and client_migrate_info() *not* renamed to hmp_device_add(), hmp_client_migrate_info(), because they're also QMP handlers. They still need to be converted to QAPI. * do_memory_dump(), do_physical_memory_dump(), do_ioport_read(), do_ioport_write() renamed do hmp_* instead of hmp_x(), hmp_xp(), hmp_i(), hmp_o(), because those names are too cryptic for my taste. * do_info_help() renamed to hmp_info_help() instead of hmp_info(), because it only covers help.

qemu-io should behave like a guest, therefore it should use BlockBackend to access the block layer. There are a couple of places where that is infeasible: First, the bdrv_debug_* functions could theoretically be mirrored in the BlockBackend, but since these are functions internal to the block layer, they should not be visible externally (qemu-io as a test tool is exempt from this). Second, bdrv_get_info() and bdrv_get_specific_info() work on a single BDS alone, therefore they should stay BDS-specific. Third, bdrv_is_allocated() mainly works on a single BDS as well. Some data may be passed through from the BDS's file (if sectors which are apparently allocated in the file are not really allocated there but just zero). [Fixed conflicts around block_acct_start() usage from Fam Zheng's "qemu-io: Account IO by aio_read and aio_write" commit. Use BlockBackend and blk_get_stats() instead of BlockDriverState. --Stefan] Signed-off-by: NMax Reitz <mreitz@redhat.com> Reviewed-by: NEric Blake <eblake@redhat.com> Message-id: 1423162705-32065-14-git-send-email-mreitz@redhat.com Signed-off-by: NStefan Hajnoczi <stefanha@redhat.com>

由 Jeff Cody 提交于
On some image chains, QEMU may not always be able to resolve the filenames properly, when updating the backing file of an image after a block job. For instance, certain relative pathnames may fail, or drives may have been specified originally by file descriptor (e.g. /dev/fd/???), or a relative protocol pathname may have been used. In these instances, QEMU may lack the information to be able to make the correct choice, but the user or management layer most likely does have that knowledge. With this extension to the block-stream api, the user is able to change the backing file of the active layer as part of the block-stream operation. This allows the change to be 'safe', in the sense that if the attempt to write the active image metadata fails, then the block-stream operation returns failure, without disrupting the guest. If a backing file string is not specified in the command, the backing file string to use is determined in the same manner as it was previously.

this patch tries to optimize zero write requests by automatically using bdrv_write_zeroes if it is supported by the format. This significantly speeds up file system initialization and should speed zero write test used to test backend storage performance.

The command's usage: dump [-p] protocol [begin] [length] [format] 'format' is used to specified the format of vmcore and can be: 1. 'elf': ELF format, without compression 2. 'kdump-zlib': kdump-compressed format, with zlib-compressed 3. 'kdump-lzo': kdump-compressed format, with lzo-compressed 4. 'kdump-snappy': kdump-compressed format, with snappy-compressed Without 'format' being set, it is same as 'elf'. And if non-elf format is specified, paging and filter is not allowed. Note: 1. The kdump-compressed format is readable only with the crash utility and makedumpfile, and it can be smaller than the ELF format because of the compression support. 2. The kdump-compressed format is the 6th edition.

Luiz does not like in 1 the fact that 2 fields are optional but one of them must be specified leading to an abuse of the QMP semantic. Kevin argumented that 2 what a clear abuse of the device field and would not be practical when reading fast some log file because the user would read "device" and think that a device is manipulated when it's in fact a node name. Documentation of 1 make it pretty clear what to do for the user. Kevin argued that all bs are node including devices ones so 2 does not make sense. Kevin also argued that rewriting the QMP block interface would not make disapear the current one. Kevin pushed the argument that making the QAPI generator compatible with the semantic of the operation would need a rewrite that no one has done yet.

Make the readline.c functionality reusable. Instead of calling monitor_printf() and monitor_flush() directly, invoke function pointers provided by the user. This way readline.c does not know about Monitor and other users will be able to make use of readline.c. Note that there is already an "opaque" argument to the ReadLineFunc callback. Consistently call it "readline_opaque" from now on to distinguish from the ReadLinePrintfFunc/ReadLineFlushFunc "opaque" argument. I also dropped the printf macro trickery since it's now highly unlikely that anyone modifying readline.c would call printf(3) directly. We no longer need this protection.
