2013-09-12coroutine: add ./configure --disable-coroutine-poolStefan Hajnoczi2-15/+43
The 'gthread' coroutine backend was written before the freelist (aka pool) existed in qemu-coroutine.c. This means that every thread is expected to exit when its coroutine terminates. It is not possible to reuse threads from a pool. This patch automatically disables the pool when 'gthread' is used. This allows the 'gthread' backend to work again (for example, tests/test-coroutine completes successfully instead of hanging). I considered implementing thread reuse but I don't want quirks like CPU affinity differences due to coroutine threads being recycled. The 'gthread' backend is a reference backend and it's therefore okay to skip the pool optimization. Note this patch also makes it easy to toggle the pool for benchmarking purposes: ./configure --with-coroutine-backend=ucontext \ --disable-coroutine-pool Reported-by: Gabriel Kerneis <gabriel@kerneis.info> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Gabriel Kerneis <gabriel@kerneis.info> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2013-09-12qemu-iotests: Adjustments due to error propagationMax Reitz6-40/+24
When opening/creating images, propagating errors instead of immediately emitting them on occurrence results in errors generally being printed on a single line rather than being split up into multiple ones. This in turn requires adjustments to some test results. Also, test 060 used a sed to filter out the test image directory and format by removing everything from the affected line after a certain keyword; this now also removes the error message itself, which can be fixed by using _filter_testdir and _filter_imgfmt. Finally, _make_test_img in common.rc did not filter out the test image directory etc. from stderr. This has been fixed through a redirection of stderr to stdout (which is already done in _check_test_img and _img_info). Signed-off-by: Max Reitz <mreitz@redhat.com>

This interface use id and name as optional parameters, to handle the case that one image contain multiple snapshots with same name which may be '', but with different id.

2013-09-12qmp: add internal snapshot support in qmp_transactionWenchao Xia3-9/+160
Unlike savevm, the qmp_transaction interface will not generate snapshot name automatically, saving trouble to return information of the new created snapshot. Although qcow2 support storing multiple snapshots with same name but different ID, here it will fail when an snapshot with that name already exist before the operation. Format such as rbd do not support ID at all, and in most case, it means trouble to user when he faces multiple snapshots with same name, so ban that case. Request with empty name will be rejected. Snapshot ID can't be specified in this interface. Signed-off-by: Wenchao Xia <xiawenc@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2013-09-12snapshot: distinguish id and name in snapshot deleteWenchao Xia9-43/+157
Snapshot creation actually already distinguish id and name since it take a structured parameter *sn, but delete can't. Later an accurate delete is needed in qmp_transaction abort and blockdev-snapshot-delete-sync, so change its prototype. Also *errp is added to tip error, but return value is kepted to let caller check what kind of error happens. Existing caller for it are savevm, delvm and qemu-img, they are not impacted by introducing a new function bdrv_snapshot_delete_by_id_or_name(), which check the return value and do the operation again. Before this patch: For qcow2, it search id first then name to find the one to delete. For rbd, it search name. For sheepdog, it does nothing. After this patch: For qcow2, logic is the same by call it twice in caller. For rbd, it always fails in delete with id, but still search for name in second try, no change to user. Some code for *errp is based on Pavel's patch. Signed-off-by: Wenchao Xia <xiawenc@linux.vnet.ibm.com> Signed-off-by: Pavel Hrdina <phrdina@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2013-09-12qcow2: Discard VM state in active L1 after creating snapshotKevin Wolf3-5/+12
During savevm, the VM state is written to the active L1 of the image and then a snapshot is taken. After that, the VM state isn't needed any more in the active L1 and should be discarded. This is implemented by this patch. The impact of not discarding the VM state is that a snapshot can never become smaller than any previous snapshot (because it would be padded with old VM state), and more importantly that future savevm operations cause unnecessary COWs (with associated flushes), which makes subsequent snapshots much slower.

For newer target architectures, glibc can be picky about the kernel version: for example, it will not run on an aarch64 system unless the kernel reports itself as at least 3.8.0. Accommodate this by enhancing the existing support for faking the kernel version so that each target can optionally specify a minimum version: if the user doesn't force a specific fake version then we will override with the minimum required version only if the real host kernel version is insufficient.

2013-09-10linux-user: Add cpu loop for AArch64Peter Maydell1-0/+82
Add the main linux-user cpu loop for AArch64. Since AArch64 has a different system call interface, doesn't need to worry about FPA emulation and may in the future keep the prefetch/data abort information in different system registers, it's simplest just to use a completely separate loop from the 32 bit ARM target, rather than peppering it with ifdefs.

2013-09-10linux-user: Don't treat AArch64 cpu names speciallyAlexander Graf1-1/+2
32-bit ARM has a lot of different names for different types of CPUs it supports. On AArch64, we don't have this, so we really don't want to execute the 32-bit logic. Stub it out for AArch64 linux-user guests.

2013-09-10target-arm: Add AArch64 gdbstub supportAlexander Graf5-1/+126
We want to be able to debug AArch64 guests. So let's add the respective gdb stub functions and xml descriptions that allow us to do so.
