Building the UMP Device Driver for Linux
----------------------------------------
Build the UMP Device Driver for Linux by running the following make command:
KDIR=<kdir_path> CONFIG=<your_config> BUILD=<build_option> make
where
kdir_path: Path to your Linux Kernel directory
your_config: Name of the sub-folder to find the required config.h file
("arch-" will be prepended)
build_option: debug or release. Debug is default.
The config.h contains following configuration parameters:
ARCH_UMP_BACKEND_DEFAULT
0 specifies the dedicated memory allocator.
1 specifies the OS memory allocator.
ARCH_UMP_MEMORY_ADDRESS_DEFAULT
This is only required for the dedicated memory allocator, and specifies
the physical start address of the memory block reserved for UMP.
ARCH_UMP_MEMORY_SIZE_DEFAULT
This specified the size of the memory block reserved for UMP, or the
maximum limit for allocations from the OS.
The result will be a ump.ko file, which can be loaded into the Linux kernel
by using the insmod command. The driver can also be built as a part of the
kernel itself.
