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.
