Intel MID PTI

=============

The Intel MID PTI project is HW implemented in Intel Atom

system-on-a-chip designs based on the Parallel Trace

Interface for MIPI P1149.7 cJTAG standard.  The kernel solution

for this platform involves the following files:

data).

An example debugging usage for this driver system:

  * Hook /dev/ttyPTI0 to syslogd.  Opening this port will also start

    a console device to further capture debugging messages to PTI.

  * Hook /dev/ttyPTI1 to modem debugging data to write to PTI HW.

    This is where n_tracerouter and n_tracesink are used.

  * Hook /dev/pti to a user-level debugging application for writing

    to PTI HW.

   *Use mipi_* Kernel Driver API in other device drivers for

  * `Use mipi_` Kernel Driver API in other device drivers for

    debugging to PTI by first requesting a PTI write address via

    mipi_request_masterchannel(1).

the use of ioctl(,TIOCSETD,) is not specific to the n_tracerouter

and n_tracesink line discpline drivers but is a generic

operation for a program to use a line discpline driver

on a tty port other than the default n_tty.
