2013-09-06block: make bdrv_co_is_allocated staticPaolo Bonzini
bdrv_is_allocated can detect coroutine context and go through a fast path, similar to other block layer functions. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-09-06block: keep bs->total_sectors up to date even for growable block devicesPaolo Bonzini
If a BlockDriverState is growable, after every write we need to check if bs->total_sectors might have changed. With this change, bdrv_getlength does not need anymore a system call. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-09-06cow: do not call bdrv_co_is_allocatedPaolo Bonzini
As we change bdrv_is_allocated to gather more information from bs and bs->file, it will become a bit slower. It is still appropriate for online jobs, but not for reads/writes. Call the internal function instead. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2013-09-06block: use BDS ref for block jobsFam Zheng
Block jobs used drive_get_ref(drive_get_by_blockdev(bs)) to avoid BDS being deleted. Now we have BDS reference count, and block jobs don't care about dinfo, so replace them to get cleaner code. It is also the safe way when BDS has no drive info. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-09-06nbd: use BlockDriverState refcntFam Zheng
Previously, nbd calls drive_get_ref() on the drive of bs. A BDS doesn't always have associated dinfo, which nbd doesn't care either. We already have BDS ref count, so use it to make it safe for a BDS w/o blockdev. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-09-06xen_disk: simplify blk_disconnect with refcntFam Zheng
We call bdrv_attach_dev when initializing whether or not bs is created locally, so call bdrv_detach_dev and let the refcnt handle the lifecycle. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-09-06migration: omit drive ref as we have bdrv_ref nowFam Zheng
block-migration.c does not actually use DriveInfo anywhere. Hence it's safe to drive ref code, we really only care about referencing BDS. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-09-06block: make bdrv_delete() staticFam Zheng
Manage BlockDriverState lifecycle with refcnt, so bdrv_delete() is no longer public and should be called by bdrv_unref() if refcnt is decreased to 0. This is an identical change because effectively, there's no multiple reference of BDS now: no caller of bdrv_ref() yet, only bdrv_new() sets bs->refcnt to 1, so all bdrv_unref() now actually delete the BDS.

2013-09-06iscsi: use bdrv_new() instead of stack structureFam Zheng
BlockDriverState structure needs bdrv_new() to initialize refcnt, don't allocate a local structure variable and memset to 0, becasue with coming refcnt implementation, bdrv_unref will crash if bs->refcnt not initialized to 1.

2013-09-06w32: Fix access to host devices (regression)Stefan Weil
QEMU failed to open host devices like \\.\PhysicalDrive0 (first hard disk) since some time (commit 8a79380b8ef1b02d2abd705dd026a18863b09020?). Those devices use hdev_open which did not use the latest API for options. This resulted in a fatal runtime error: Block protocol 'host_device' doesn't support the option 'filename' Duplicate code from raw_open to fix this.

Add a -n option to skip volume creation on qemu-img convert. This is useful for targets such as rbd / ceph, where the target volume may already exist; we cannot always rely on qemu-img convert to create the image, as dependent on the output format, there may be parameters which are not possible to specify through the qemu-img convert command line.

2013-09-03target-i386: Use #defines instead of magic numbers for CPUID cache infoEduardo Habkost
This is an attempt to make the CPUID cache topology code clearer, by replacing the magic numbers in the code with #defines, and moving all the cache information to the same place in the file. I took care of comparing the assembly output of compiling target-i386/cpu.c before and after applying this change, to make sure not a single bit was changed on cpu_x86_cpuid() before and after applying this patch (unfortunately I had to manually check existing differences, because of __LINE__ expansions on object_class_dynamic_cast_assert() calls). This even keeps the code bug-compatible with the previous version: today the cache information returned on AMD cache information leaves (CPUID 0x80000005 & 0x80000006) do not match the information returned on CPUID leaves 2 and 4. The L2 cache information on CPUID leaf 2 also doesn't match the information on CPUID leaf 2. The new constants should make it easier to eventually fix those inconsistencies. All inconsistencies I have found are documented in code comments.

Change that by only implementing the ext8s and ext16s ops on MIPS32R2 so that optimizations can be done by the optimizer.
