Intel PTI implementaiton of MIPI 1149.7. The PTI (Parallel Trace Interface) driver directs trace data routed from various parts in the system out through an Intel Penwell PTI port and out of the mobile device for analysis with a debugging tool (Lauterbach or Fido). Though n_tracesink and n_tracerouter line discipline drivers are used to extract modem tracing data to the PTI driver and other parts of an Intel mobile solution, the PTI driver can be used independent of n_tracesink and n_tracerouter. You should select this driver if the target kernel is meant for an Intel Atom (non-netbook) mobile device containing a MIPI P1149.7 standard implementation.

drivers/misc/intel/pti: Rename the header file to free up the namespace We'd like to use the 'PTI' acronym for 'Page Table Isolation' - free up the namespace by renaming the <linux/pti.h> driver header to <linux/intel-pti.h>.

drivers/misc/pti.c: give 'comm' function scope in pti_control_frame_built_and_sent() In drivers/misc/pti.c::pti_control_frame_built_and_sent() we assign 'comm' to 'thread_name_p' if (!thread_name). The problem is that 'comm' then goes out of scope and later we use 'thread_name_p' which now refers to an out-of-scope variable. To fix that, simply move 'comm' up to have function scope.

Though n_tracesink and n_tracerouter line discipline drivers are used to extract modem tracing data to the PTI driver and other parts of an Intel mobile solution, the PTI driver can be used independent of n_tracesink and n_tracerouter. You should select this driver if the target kernel is meant for an Intel Atom (non-netbook) mobile device containing a MIPI P1149.7 standard implementation.

The upside is that we look like we can introduce tty_port_easy_open and put it directly as tty_operations->open to drivers doing nothing in open and using tty_port_register_device.

The PTI (Parallel Trace Interface) driver directs trace data routed from various parts in the system out through an Intel Penwell PTI port and out of the mobile device for analysis with a debugging tool (Lauterbach or Fido). Though n_tracesink and n_tracerouter line discipline drivers are used to extract modem tracing data to the PTI driver and other parts of an Intel mobile solution, the PTI driver can be used independent of n_tracesink and n_tracerouter. You should select this driver if the target kernel is meant for an Intel Atom (non-netbook) mobile device containing a MIPI P1149.7 standard implementation.

misc: pti, use tty_port_register_device So now we have enough of tty_ports, so we can signal the TTY layer to use them by tty_port_register_device. The upside is that we look like we can introduce tty_port_easy_open and put it directly as tty_operations->open to drivers doing nothing in open and using tty_port_register_device. Because the easy open can obtain a tty_port rather easily from a tty now. Heh, what a nice by-product.

TTY: call tty_port_destroy in the rest of drivers After commit "TTY: move tty buffers to tty_port", the tty buffers are not freed in some drivers. This is because tty_port_destructor is not called whenever a tty_port is freed. This was an assumption I counted with but was unfortunately untrue. So fix the drivers to fulfil this assumption. To be sure, the TTY buffers (and later some stuff) are gone along with the tty_port, we have to call tty_port_destroy at tear-down places. This is mostly where the structure containing a tty_port is freed. This patch does exactly that -- put tty_port_destroy at those places.
