[Qemu-devel] [PATCH 0/6] Fix multifd with big number of channels

Posted by Juan Quintela 16 weeks ago
Hi

When we have much more channels than cpus, we end having failures when
writting to sockets. This series:
- add some traces
- fix some of the trouble with serialization of creating the
  threads/channels in proper order.
- Ask for help with the last patch.  See documentation there.

Please, review.

Juan Quintela (6):
  migration: Add traces for multifd terminate threads
  migration: Make global sem_sync semaphore by channel
  migration: Make sure that all multifd channels have been created
  migration: Make multifd threads wait until all have been created
  migration: add some multifd traces
  RFH: We lost "connect" events

Hi,

This series failed the asan build test. Please find the testing commands and
their output below. If you have Docker installed, you can probably reproduce it
locally.
