a part of assembly-howto :) Meanwhile, here's an example of a minimum dumb kernel module (module.asm) (source is based on example by mammon_ from APJ #8): section .text global init_module global cleanup_module global kernel_version extern printk init_module: push dword str1 call printk pop eax xor eax,eax ret cleanup_module: push dword str2 call printk pop eax ret str1 db "init_module done",0xa,0 str2 db "cleanup_module done",0xa,0 kernel_version db "2.2.18",0 Small, huh? :) > You seem to be under the same mistaken impression as many people that > assembler is always quicker. I'm writting programs for microcontrollers in assmbler - te final code fits in about 2000 lines and takes about 2kB... I know how much would it take, if I wrote it in C or BASIC... I know how it looks from "very hardware" side / experience. C uses libc and some others... that takes time, so i think it's slower. Well, it not MUST be written in assembler... if C would be easier, i would use C... but I thought that asm would be simplier/faster. > Sometimes it is, sometimes it isn't.

In uC I had timers, by which i could call an interput after demanded time. Is there something like this under linux? > See "Linux Device Drivers" by Rubini, A., published by O'Reilly. (...) I would really love to, but i have no ability to buy this :(((( There must be some online documentaion...? Tanks!
