A kickstart manual and a practical approach to learn internals of how Linux Kernel and Device Driver works.
Update [2016]: This is also a base repository, which should be cloned and used by participants of HP-E Mastermaze.
- Create a Linux kernel driver which allocates a 4k byte memory page and shares it with user-process which requests read access.
- The driver is expected to listen to on /dev/hpehackon. The driver should return the address of the 4k byte memory when user process does a mmap() on the fd associated with /dev/hpehackon.
- When the userprocess reads the first 256 bytes as a string from the return address, it should contain “HPE HACKATHON 2016!!” within it.
- Linux
- Device Drivers written in code C
- File Operations and Memory allocation via mmap.
[Guideline]
- Platform: Linux
- Note: The driver should be developed by you and the executable userprocess given in this repository should able to communicate with driver listening on /dev/hpehackon.
- Install Git and Clone this repo via
# sudo apt-get install git
# sudo su
# git clone [email protected]:mayurah/Linux-Device-Driver.git
- do a chmod on user process
# chmod +x uprog_validate
# ./uprog_validate
