Subject: 6b41030fdc790 broke dmatest badly
Date: Fri, 4 Sep 2020 20:34:01 +0300 [thread overview]
Message-ID: <20200904173401.GH1891694@smile.fi.intel.com> (raw)
It becomes a bit annoying to fix dmatest after almost each release.
The commit 6b41030fdc79 ("dmaengine: dmatest: Restore default for channel")
broke my use case when I tried to start busy channel.
So, before this patch
...
echo "busy_chan" > channel
echo 1 > run
sh: write error: Device or resource busy
[ 1013.868313] dmatest: Could not start test, no channels configured
After I have got it run on *ALL* available channels.
dmatest compiled as a module.
Fix this ASAP, otherwise I will send revert of this and followed up patch next
week.
