Subject: [PATCH] radeon: Use only a single work queue thread for crt
Date: Fri,  2 Aug 2019 17:09:08 -0700	[thread overview]
Message-ID: <20190803000908.5310-1-andi@firstfloor.org> (raw)

From: Andi Kleen <ak@linux.intel.com>

I got tired of seeing a lot of radeon-crt kernel threads in ps on my
workstation, one for each CPU and one for each display, which never use any CPU time.
Surely a single kernel thread is enough to handle the display.
