 ### Hardware Trace Macro
 Expoitation of HTM is limited to POWER9 NestHTM from the powerpc host.

 Using HTM requires a kernel built with both `CONFIG_PPC_MEMTRACE=y`
 (v4.14) and `CONFIG_SCOM_DEBUGFS=y`. debugfs should be mounted at
 `/sys/kernel/debug`.
 
-pdbg provides `htm_trace` which will configure the hardware and
-start tracing as well as `htm_analyse` which still stop the trace and
-dump the result to a file.
