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 Octeon shared memory malloc
|
|
|
|
This malloc is based on ptmalloc2, which is the malloc
|
|
implementation of glibc. Source code and more information
|
|
on this can be found at http://www.malloc.de/en/index.html.
|
|
Please see the individual files for licensing terms.

|
|
|
The main change to the code modifies the way the malloc
|
|
gets memory from the system. Under Linux/Unix, malloc
|
|
uses the brk or memmap sytem calls to request more memory.
|
|
In this implementation, memory regions must be explicitly
|
|
given to malloc by the application.
