14 - A u32 providing a total count of errors since the driver was loaded. The
15 only errors counted here are those returned from the hcall, H_COP_OP.
18 - The most recent non-zero return code from the H_COP_OP hcall. -EBUSY is not
19 recorded here (the hcall will retry until -EBUSY goes away).
22 - The process ID of the process who received the most recent error from the
