Subject: [gentoo-embedded] writing device drivers howto |

Hi list! |
| 17 |
|
| 18 |
This is some sort of offtopic, but I guess this is the best point to ask. |
| 19 |
I have an embedded system running linux. I need to access some special |
| 20 |
registers (e.g. containing the clock cycles, ...) So I managed to write a |
| 21 |
very simple module, which is able to access the registers. But what makes |
| 22 |
me worrying now, is the way, I have to get the data into my user-space |
| 23 |
application. Is there some documentation, concerning writing device |
| 24 |
drivers and accessing them from the user space anywhere? I found some |
| 25 |
documentation, but either I did not understand the part about getting data |
| 26 |
from kernel space into user space, or it was just simply missing. |
| 27 |
|
| 28 |
Maybe anyone here can help me out! |

Thanks in advance and kind regards! |
