V5 can be found here: http://www.mail-archive.com/qemu-devel@nongnu.org/msg36678.html Change from v5: * The earlier code was hitting a null pointer dereference error at cpu_exit() with IO thread disabled. This version adds a signal handler for SIGUSR2 to call qemu_service_io() which calls cpu_exit() The following series implements... --- Aneesh Kumar K.V (1): Introduce threadlets Gautham R Shenoy (2): Make paio subsystem use threadlets Add helper functions for virtio-9p to use threadlets Makefile.objs | 3 - docs/async-support.txt | 141 +++++++++++++++++++++++++++++++++++ hw/virtio-9p.c | 165 ++++++++++++++++++++++++++++++++++++++++- posix-aio-compat.c | 195 ++++++++++-------------------------------------- qemu-threadlets.c | 190 +++++++++++++++++++++++++++++++++++++++++++++++ qemu-threadlets.h | 49 ++++++++++++ vl.c | 3 + 7 files changed, 588 insertions(+), 158 deletions(-) create mode 100644 docs/async-support.txt create mode 100644 qemu-threadlets.c create mode 100644 qemu-threadlets.h -- arun
