Currently, the kernel uses
[LM]FENCE; RDTSC
in the timekeeping code, to guarantee monotonicity of time where the
*FENCE is selected based on vendor.
Replace that sequence with RDTSCP which is faster or on-par and gives
the same guarantees.

Currently to read a response from the TPM device an application needs
provide big enough buffer for the whole response and read it in one go.
The application doesn't know how big the response it beforehand so it
always needs to maintain a 4K buffer and read the max (4K).

Hi Jian,
Not clear to me why should be + instead of *.

[s]
1000 * (1/Hz) = period in milliseconds (1 sample sampling time) [ms]
n * 1000 * (1/Hz) = n times period in milliseconds (n times sample sampling
time) [ms]

Hi Julia & the RT team,
The following program might make a good addition to the rt
test suite. It tests the reliability of PTRACE_SINGLESTEP.
It does by default 10,000 ssteps against a simple,
spinner tracee. Also by default, it spins off ten of these
tracer/tracee pairs, all of which are to run

Query the queue information of the current NIC
such as BD size, queue header and tail pointer.
This patch adds support for debugfs command:
echo queue info 1 > cmd
it can print queue config information...
