Allocating Channels
-------------------
-Channels are required to be configured prior to starting the test run.
-Attempting to run the test without configuring the channels will fail.
+Channels do not need to be configured prior to starting a test run. Attempting
+to run the test without configuring the channels will result in testing any
+channels that are available.
Example::
% echo 1 > /sys/module/dmatest/parameters/run
- dmatest: Could not start test, no channels configured
+ dmatest: No channels configured, continue with any
Channels are registered using the "channel" parameter. Channels can be requested by their
name, once requested, the channel is registered and a pending thread is added to the test list.
