Author: manu Date: Tue May 19 09:04:35 2020 New Revision: 361247 URL: https://svnweb.freebsd.org/changeset/base/361247 Log: linuxkpi: Add irq_work.h Since handlers are call in a thread context we can simply use a workqueue to emulate those functions. The DRM code was patched to do that already, having it in linuxkpi allows us to not patch the upstream code.
