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. |
