-What:   /proc/<pid>/oom_adj
-When:   August 2012
-Why:    /proc/<pid>/oom_adj allows userspace to influence the oom killer's
-        badness heuristic used to determine which task to kill when the kernel
-        is out of memory.
-
-        The badness heuristic has since been rewritten since the introduction of
-        this tunable such that its meaning is deprecated.  The value was
-        implemented as a bitshift on a score generated by the badness()
-        function that did not have any precise units of measure.  With the
-        rewrite, the score is given as a proportion of available memory to the
-        task allocating pages, so using a bitshift which grows the score
-        exponentially is, thus, impossible to tune with fine granularity.
-
-        A much more powerful interface, /proc/<pid>/oom_score_adj, was
-        introduced with the oom killer rewrite that allows users to increase or
-        decrease the badness score linearly.  This interface will replace
-        /proc/<pid>/oom_adj.
-
-        A warning will be emitted to the kernel log if an application uses this
-        deprecated interface.  After it is printed once, future warnings will be
-        suppressed until the kernel is rebooted.

+Description:
+                This folder includes the attributes related with PPI (Physical
+                Presence Interface). Only if TPM is supported by BIOS, this
+                folder makes sence. The folder path can be got by command
+                'find /sys/ -name 'pcrs''. For the detail information of PPI,
+                please refer to the PPI specification from
+                http://www.trustedcomputinggroup.org/

+Description:
+                This attribute shows the request for an operation to be
+                executed in the pre-OS environment. It is the only input from
+                the OS to the pre-OS environment. The request should be an
+                integer value range from 1 to 160, and 0 means no request.
+                This file can be read and written.
