1Building the UMP Device Driver for Linux
2----------------------------------------
3
4Build the UMP Device Driver for Linux by running the following make command:
5
6KDIR=<kdir_path> CONFIG=<your_config> BUILD=<build_option> make
7
8where
9 kdir_path: Path to your Linux Kernel directory
10 your_config: Name of the sub-folder to find the required config.h file
11 ("arch-" will be prepended)
12 build_option: debug or release. Debug is default.
13
14The config.h contains following configuration parameters:
15
16ARCH_UMP_BACKEND_DEFAULT
17 0 specifies the dedicated memory allocator.
18 1 specifies the OS memory allocator.
19ARCH_UMP_MEMORY_ADDRESS_DEFAULT
20 This is only required for the dedicated memory allocator, and specifies
21 the physical start address of the memory block reserved for UMP.
22ARCH_UMP_MEMORY_SIZE_DEFAULT
23 This specified the size of the memory block reserved for UMP, or the
24 maximum limit for allocations from the OS.
25
26The result will be a ump.ko file, which can be loaded into the Linux kernel
27by using the insmod command. The driver can also be built as a part of the
28kernel itself.
