make use of it where possible.
This primarily brings in support for newer hardware, and FreeBSD is not yet
able to support the abundance of IRQs on new hardware and many features in the
Ethernet driver.
Because of the changes to IRQs in the Simple Executive, we have to maintain our
own list of Octeon IRQs now, which probably can be pared-down and be specific
to the CIU interrupt unit soon, and when other interrupt mechanisms are added
they can maintain their own definitions.
Remove unmasking of interrupts from within the UART device now that the
function used is no longer present in the Simple Executive. The unmasking
seems to have been gratuitous as this is more properly handled by the buses
above the UART device, and seems to work on that basis.
Readme for the OCTEON Executive Library
The OCTEON Executive Library provides runtime support and hardware
abstraction for the OCTEON processor. The executive is composed of the
libcvmx.a library as well as header files that provide
functionality with inline functions.
Usage:
The libcvmx.a library is built for every application as part of the
application build. (Please refer to the 'related pages' section of the
HTML documentation for more information on the build system.)
Applications using the executive should include the header files from
$OCTEON_ROOT/target/include and link against the library that is built in
the local obj directory. Each file using the executive
should include the following two header files in order:
#include "cvmx-config.h"
#include "cvmx.h"
The cvmx-config.h file contains configuration information for the
executive and is generated by the cvmx-config script from an
'executive-config.h' file. A sample version of this file is provided
in the executive directory as 'executive-config.h.template'.
Copy this file to 'executive-config.h' into the 'config' subdirectory
of the application directory and customize as required by the application.
Applications that don't use any simple executive functionality can omit
the cvmx-config.h header file. Please refer to the examples for a
demonstration of where to put the executive-config.h file and for an
example of generated cvmx-config.h.
For file specific information please see the documentation within the
source files or the HTML documentation provided in docs/html/index.html.
