2014-08-15test-coroutine: add baseline test that times the cost of function callsPaolo Bonzini1-0/+24
This can be used to compute the cost of coroutine operations. In the end the cost of the function call is a few clock cycles, so it's pretty cheap for now, but it may become more relevant as the coroutine code is optimized. For example, here are the results on my machine: Function call 100000000 iterations: 0.173884 s Yield 100000000 iterations: 8.445064 s Lifecycle 1000000 iterations: 0.098445 s Nesting 10000 iterations of 1000 depth each: 7.406431 s One yield takes 83 nanoseconds, one enter takes 97 nanoseconds, one coroutine allocation takes (roughly, since some of the allocations in the nesting test do hit the pool) 739 nanoseconds: (8.445064 - 0.173884) * 10^9 / 100000000 = 82.7 (0.098445 * 100 - 0.173884) * 10^9 / 100000000 = 96.7 (7.406431 * 10 - 0.173884) * 10^9 / 100000000 = 738.9 Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2014-08-15thread-pool: avoid deadlock in nested aio_poll() callsStefan Hajnoczi1-0/+6
The thread pool has a race condition if two elements complete before thread_pool_completion_bh() runs: If element A's callback waits for element B using aio_poll() it will deadlock since pool->completion_bh is not marked scheduled when the nested aio_poll() runs. Fix this by marking the BH scheduled while thread_pool_completion_bh() is executing. This way any nested aio_poll() loops will enter thread_pool_completion_bh() and complete the remaining elements.

2014-08-15vmdk: Optimize cluster allocationFam Zheng1-82/+140
This drops the unnecessary bdrv_truncate() from, and also improves, cluster allocation code path. Before, when we need a new cluster, get_cluster_offset truncates the image to bdrv_getlength() + cluster_size, and returns the offset of added area, i.e. the image length before truncating. This is not efficient, so it's now rewritten as: - Save the extent file length when opening. - When allocating cluster, use the saved length as cluster offset. - Don't truncate image, because we'll anyway write data there: just write any data at the EOF position, in descending priority: * New user data (cluster allocation happens in a write request). * Filling data in the beginning and/or ending of the new cluster, if not covered by user data: either backing file content (COW), or zero for standalone images. One major benifit of this change is, on host mounted NFS images, even over a fast network, ftruncate is slow (see the example below). This change significantly speeds up cluster allocation. Comparing by converting a cirros image (296M) to VMDK on an NFS mount point, over 1Gbe LAN: $ time qemu-img convert cirros-0.3.1.img /mnt/a.raw -O vmdk Before: real 0m21.796s user 0m0.130s sys 0m0.483s After: real 0m2.017s user 0m0.047s sys 0m0.190s We also get rid of unchecked bdrv_getlength() and bdrv_truncate(), and get a little more documentation in function comments.

2014-08-15block: New bdrv_nb_sectors()Markus Armbruster2-10/+20
A call to retrieve the image size converts between bytes and sectors several times: * BlockDriver method bdrv_getlength() returns bytes. * refresh_total_sectors() converts to sectors, rounding up, and stores in total_sectors. * bdrv_getlength() converts total_sectors back to bytes (now rounded up to a multiple of the sector size). * Callers wanting sectors rather bytes convert it right back. Example: bdrv_get_geometry(). bdrv_nb_sectors() provides a way to omit the last two conversions. It's exactly bdrv_getlength() with the conversion to bytes omitted. It's functionally like bdrv_get_geometry() without its odd error handling. Reimplement bdrv_getlength() and bdrv_get_geometry() on top of bdrv_nb_sectors().
