| 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. |
