We have an unfortunate naming clash between the functions ldl_p, stl_p, etc defined in bswap.h (which have semantics "load/store in host endianness") and the #defines of the same name in cpu-all.h (which have the semantics "load/store in target endianness"). Fortunately it turns out that the only users of the bswap.h functions are all within bswap.h itself, so we can simply rename them to include a _he_ infix for "host endianness".

2014-05-19block: optimize zero writes with bdrv_write_zeroesPeter Lieven1-0/+1
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.

2014-05-15qapi: Replace start_optional()/end_optional() by optional()Markus Armbruster2-6/+4
Semantics of end_optional() differ subtly from the other end_FOO() callbacks: when start_FOO() succeeds, the matching end_FOO() gets called regardless of what happens in between. end_optional() gets called only when everything in between succeeds as well. Entirely undocumented, like all of the visitor API. The only user of Visitor Callback end_optional() never did anything, and was removed in commit 9f9ab46. I'm about to clean up error handling in the generated visitor code, and end_optional() is in my way. No users mean no test cases, and making non-trivial cleanup transformations without test cases doesn't strike me as a good idea. Drop end_optional(), and rename start_optional() to optional(). We can always go back to a pair of callbacks when we have an actual need.

On the x86, some devices need access to the CPU reset pin (INIT#). Provide a generic service to do this, using one of the internal cpu_interrupt targets. Generalize the PPC-specific code for CPU_INTERRUPT_RESET to other targets. Since PPC does not support migration across QEMU versions (its machine types are not versioned yet), I picked the value that is used on x86, CPU_INTERRUPT_TGT_INT_1. Consequently, TGT_INT_2 and TGT_INT_3 are shifted down by one while keeping their value. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Reviewed-by: Michael S.

Now that we have a CPU object with a reset method, it is better to keep the KVM reset close to the CPU reset. Using qemu_register_reset as we do now keeps them far apart. With this patch, PPC no longer calls the kvm_arch_ function, so it can get removed there. Other arches call it from their CPU reset handler, and the function gets an ARMCPU/X86CPU/S390CPU. Note that ARM- and s390-specific functions are called kvm_arm_* and kvm_s390_*, while x86-specific functions are called kvm_arch_*. That follows the convention used by the different architectures.

The code which patches x86 jump instructions assumes it can do an unaligned write of a uint32_t. This is actually safe on x86, but it's still undefined behaviour. We have infrastructure for doing efficient unaligned accesses which doesn't engage in undefined behaviour, so use it. This is technically fractionally less efficient, at least with gcc 4.6; instead of one instruction: 7b2: 89 3e mov %edi,(%rsi) we get an extra spurious store to the stack slot: 7b2: 89 7c 24 64 mov %edi,0x64(%rsp) 7b6: 89 3e mov %edi,(%rsi) Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Richard Henderson <rth@twiddle.net>

The immediately visible effect of this patch is that it fixes committing a temporary snapshot to its backing file. Previously, it would fail with a "permission denied" error because bdrv_inherited_flags() forced the backing file to be read-only, ignoring the r/w reopen of bdrv_commit(). The bigger problem this revealed is that the original open flags must actually only be applied to the temporary snapshot, and the original image file must be treated as a backing file of the temporary snapshot and get the right flags for that.

If target block driver forces compression, qemu-img convert needs to write by cluster size as well as "-c" option. Particularly, this applies for converting to VMDK streamOptimized format. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

and rebase monitor_handle_fd_param() to it. (Note that this will slightly change the behavior when the qemu_parse_fd() branch is selected and it fails: we now report (and in case of QMP, set) the error immediately, rather than allowing the caller to set its own error message (if any)).

2014-05-07xen_disk: add discard supportOlaf Hering1-0/+7
Implement discard support for xen_disk. It makes use of the existing discard code in qemu. The discard support is enabled unconditionally. The tool stack may provide a property "discard-enable" in the backend node to optionally disable discard support. This is helpful in case the backing file was intentionally created non-sparse to avoid fragmentation.
