- USAGE
- ==============================================================================
- ./memalloc_load.sh

- What is memalloc?
- ===============================================================================
- memalloc is a test environment specific memory allocation kernel driver.
- It uses memory left outside linux memory management, divides it into chunks and
- gives base addresses to processes for these chunks(= a block of memory).
- It has been written for test memory purposes for a very specific test
- environment and nothing more.
- ===============================================================================
- Loading the memalloc kernel driver
- ===============================================================================
- 1. compile the kernel driver in software/linux/memalloc
- > make
- 2. For testing load kernel driver with:
- >./memalloc_load.sh
- ...or if you want to specify the max size in MB of linear memory:
- >./memalloc_load.sh alloc_size=400
- ...or if you want to specify the base address of linear memory:
- >./memalloc_load.sh alloc_base=0x42000000
- ...or both:
- >./memalloc_load.sh alloc_base=0x42000000 alloc_size=400
- 3. Debugging:
- the device node should show up in the the directory /dev
- The device should show up in the list /proc/devices
- > ls /dev
- > cat /proc/devices
- Kernel messages can be viewed with
- > dmesg
- More kernel debug prints can be enabled in the Makefile
