-config MM_SMALL
- bool "Small memory model"
- default n
- ---help---
- Each memory allocation has a small allocation overhead. The size
- of that overhead is normally determined by the "width" of the
- address support by the MCU. MCUs that support 16-bit addressability
- have smaller overhead than devices that support 32-bit addressability.
- However, there are many MCUs that support 32-bit addressability *but*
- have internal SRAM of size less than or equal to 64Kb. In this case,
- CONFIG_MM_SMALL can be defined so that those MCUs will also benefit
- from the smaller, 16-bit-based allocation overhead.
-
-config MM_REGIONS
- int "Number of memory regions"
- default 1
- ---help---
- If the architecture includes multiple, non-contiguous regions of
- memory to allocate from, this specifies the number of memory regions
- that the memory manager must handle and enables the API
- mm_addregion(start, end);
-
-config ARCH_HAVE_HEAP2
- bool
-
-config HEAP2_BASE
- hex "Start address of second heap region"
- default 0x00000000
- depends on ARCH_HAVE_HEAP2
- ---help---
- The base address of the second heap region.
-
-config HEAP2_SIZE
- int "Size of the second heap region"
- default 0
- depends on ARCH_HAVE_HEAP2
- ---help---
- The size of the second heap region.
-
-config GRAN
- bool "Enable Granule Allocator"
- default n
- ---help---
- Enable granual allocator support. Allocations will be aligned to the
- granule size; allocations will be in units of the granule size.
- Larger granules will give better performance and less overhead but
- more losses of memory due to alignment and quantization waste.
-
- NOTE: The current implementation also restricts the maximum
- allocation size to 32 granaules. That restriction could be
- eliminated with some additional coding effort.
-
-config GRAN_SINGLE
- bool "Single Granule Allocator"
- default n
- depends on GRAN
- ---help---
- Select if there is only one instance of the granule allocator (i.e.,
- 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
- bool "Interrupt level support"
- default n
- depends on GRAN
- ---help---
- 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_GRAN
- bool "Granule Allocator Debug"
- default n
- depends on GRAN && DEBUG
- ---help---
- Just like CONFIG_DEBUG_MM, but only generates ouput from the gran
- allocation logic.
