From 1212aa1c8c9ca34642f7737e1edaa96c9ce3d7dd Mon Sep 17 00:00:00 2001 From: Ryan Grimm Date: Mon, 19 Jan 2015 11:52:50 -0600 Subject: cxl: Enable CAPP recovery Turning snoops on is the last step in CAPP recovery. Sapphire is expected to have reinitialized the PHB and done the previous recovery steps. Add mode argument to opal call to do this. Driver can turn snoops off although it does not currently.
