@ -299,6 +299,11 @@ defconfig -- This is a configuration file similar to the Linux
gran_initialize will be called only once. In this case, (1) there
are a few optimizations that can can be done and (2) the GRAN_HANDLE
is not needed.
CONFIG_GRAN_INTR - Normally mutual exclusive access to granule allocator
data is assured using a semaphore. If this option is set then, instead,
mutual exclusion logic will disable interrupts. While this options is
more invasive to system performance, it will also support use of the
granule allocator from interrupt level logic.
CONFIG_DEBUG_GRAM
Just like CONFIG_DEBUG_MM, but only generates ouput from the gran
allocation logic.
