powerpc/pseries: Export hardware trace macro dump via debugfs
This patch adds debugfs interface to export Hardware Trace Macro (HTM)
function data in a LPAR. New hypervisor call "H_HTM" has been
defined to setup, configure, control and dump the HTM data.
This patch supports only dumping of HTM data in a LPAR.
New debugfs folder called "htmdump" has been added under
/sys/kernel/debug/arch path which contains files need to
pass required parameters for the H_HTM dump function. New Kconfig
option called "CONFIG_HTMDUMP" is added in platform/pseries
for the same.
With this module loaded, list of files in debugfs path
/sys/kernel/debug/powerpc/htmdump
