| Post subject: | How to make a fully preemptable kernel ? |
I want my kernel to be fully preemptable as QNX(as I know), but I don't know how it is achieved ! By not using memory-variables ? Is the following function preemptable ? void test_kernel_function() { int i=100000; while(i--); } ..if not,how shoudl I chage it to be ? What I expect from the above function is that,when it is preempted it will set i=100000 so when the preemted process gains back controll it will have an undefined value in i ! Am I completly on the wrong way ? I would also like to discuss microkernels in detail (general concepts,message-passing,memeory managment,etc..). If you also feel so(and have patience for me), drop me an email: [email protected] thanks in advance |
