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. I ran the following 2 tests on my internal SSD with a 50G QCOW2 container and on an attached iSCSI storage. a) mkfs.ext4 -E lazy_itable_init=0,lazy_journal_init=0 /dev/vdX QCOW2 [off] [on] [unmap] ----- runtime: 14secs 1.1secs 1.1secs filesize: 937M 18M 18M iSCSI [off] [on] [unmap] ---- runtime: 9.3s 0.9s 0.9s b) dd if=/dev/zero of=/dev/vdX bs=1M oflag=direct QCOW2 [off] [on] [unmap] ----- runtime: 246secs 18secs 18secs filesize: 51G 192K 192K throughput: 203M/s 2.3G/s 2.3G/s iSCSI* [off] [on] [unmap] ---- runtime: 8mins 45secs 33secs throughput: 106M/s 1.2G/s 1.6G/s allocated: 100% 100% 0% * The storage was connected via an 1Gbit interface. It seems to internally handle writing zeroes via WRITESAME16 very fast. Signed-off-by: NPeter Lieven <pl@kamp.de> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

Dumping guest memory is available to specify the dump format now. This patch adds options '-z|-l|-s' to HMP command dump-guest-memory to specify dumping in kdump-compression format, with zlib/lzo/snappy compression. And without these options ELF format will be used.

Make monitor command 'dump-guest-memory' be able to dump in kdump-compressed format. 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.

This patch fixes a timing issue that migrate command (without -d) does not block in some cases. The original version of hmp.c:hmp_migrate_status_cb checks if the migration status is 'active' or not to detect the completion of a migration. However, if this function is executed when the migration status is stil 'setup' (the status before 'active'), migration command returns immediately even if the user does not specify -d option.

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.

Make "drive_backup" available on the HMP monitor: drive_backup [-n] [-f] device target [format] The -n flag requests QEMU to reuse the image found in new-image-file, instead of recreating it from scratch. The -f flag requests QEMU to copy the whole disk, so that the result does not need a backing file. Note that this flag *must* currently be passed since the other sync modes ('none' and 'top') have not been implemented yet. Requiring it ensures that "drive_backup" behaves like "drive_mirror".

HMP is meant for humans and you should notice it.

This patch adds support for TPM command line options. The command line options supported here are ./qemu-... -tpmdev passthrough,path=<path to TPM device>,id=<id> -device tpm-tis,tpmdev=<id>,id=<other id> and ./qemu-... -tpmdev help where the latter works similar to -soundhw help and shows a list of available TPM backends (for example 'passthrough'). Using the type parameter, the backend is chosen, i.e., 'passthrough' for the passthrough driver. The interpretation of the other parameters along with determining whether enough parameters were provided is pushed into the backend driver, which needs to implement the interface function 'create' and return a TPMDriverOpts structure if the VM can be started or 'NULL' if not enough or bad parameters were provided. Monitor support for 'info tpm' has been added. It for example prints the following: (qemu) info tpm TPM devices: tpm0: model=tpm-tis \ tpm0: type=passthrough,path=/dev/tpm0,cancel-path=/sys/devices/pnp0/00:09/cancel Signed-off-by: NStefan Berger <stefanb@linux.vnet.ibm.com> Reviewed-by: NCorey Bryant <coreyb@linux.vnet.ibm.com> Reviewed-by: NJoel Schopp <jschopp@linux.vnet.ibm.com> Message-id: 1361987275-26289-2-git-send-email-stefanb@linux.vnet.ibm.com Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>
