| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 6d32717 "aio / timers: Remove alarm timers" has issues: 1. It silently ignores -clock for backward compatibility. Incompatible change: -clock help no longer terminates the program. Tolerable. 2. Failed to update option documentation. In particular, -help still advises users to try -clock help for available timers. Drop all documentation on -clock. 3. The 'query-alarm-clock' example in docs/writing-commands.txt no longer works, and needs to be redone. Can't do that right now, so I just stick in a FIXME.

* AioContext: speed up aio_notifyPaolo Bonzini2014-07-091-0/+104
| | | | | | | | | | | | | | | | | | | | | In many cases, the call to event_notifier_set in aio_notify is unnecessary. In particular, if we are executing aio_dispatch, or if aio_poll is not blocking, we know that we will soon get to the next loop iteration (if necessary); the thread that hosts the AioContext's event loop does not need any nudging. The patch includes a Promela formal model that shows that this really works and does not need any further complication such as generation counts. It needs a memory barrier though. The generation counts are not needed because any change to ctx->dispatching after the memory barrier is okay for aio_notify. If it changes from zero to one, it is the right thing to skip event_notifier_set. If it changes from one to zero, the event_notifier_set is unnecessary but harmless.

Here we are introducing following changes: - new function qemu_get_ram_block_host_ptr() returns host pointer to the ram block, it is needed to calculate offset of specific region in the host memory - new field mmap_offset is added to the VhostUserMemoryRegion. It contains offset where specific region starts in the mapped memory. As there is stil no wider adoption of vhost-user agreement was made that we will not bump version number due to this change - other fileds in VhostUserMemoryRegion struct are not changed, as they are all needed for usermode app implementation - region data is not taken from ram_list.blocks anymore, instead we use region data which is alredy calculated for use in vhost-net - Now multiple regions can have same FD and user applicaton can call mmap() multiple times with the same FD but with different offset (user needs to take care for offset page alignment) Signed-off-by: Damjan Marion <damarion@cisco.com> Acked-by: Michael S.

* qmp: add qmp-events.txt backLuiz Capitulino2014-06-271-0/+551
| | | | | | | | | | | | | | | The conversion of events to the QAPI, resulted in the removal of the docs/qmp/qmp-events.txt file. This was done to avoid having duplicated information between qmp-events.txt and qapi-event.json. However, qmp-events.txt contains examples and we're still not sure how to proper install QAPI docs in the host. To avoid harming users, it's better to re-add qmp-events.txt for now and deal with the duplication later.
