Subject: [RFC PATCH 0/2] cxl: Add support for disabling CAPP when unloading CXL
Date: Fri, 25 Jan 2019 10:41:29 +0530 [thread overview]
Message-ID: <20190125051131.29351-1-vaibhav@linux.ibm.com> (raw)
Recent updates to OPAL have implemented necessary infrastructure [1] to disable
CAPP and switch PHB back to PCIE mode during fast reset. This small patch-set
uses the same OPAL infrastructure to force disable of CAPP when CXL module is
unloaded via rmmod.
