[PATCH v2 0/3] iothread and irqfd support

Posted by Jinhao Fan 3 years, 5 months ago

This patch series adds support for using a seperate iothread for NVMe
IO emulation, which brings the potential of applying polling. The
first two patches implements support for irqfd, which solves thread
safety problems for interrupt emulation outside the main loop thread.

Changes since v1:
 - Avoid duplicate initilization of cq timer

Jinhao Fan (3):
  hw/nvme: support irq(de)assertion with eventfd
  hw/nvme: use KVM irqfd when available
  hw/nvme: add iothread support
