[rtl] Error with sem_getvalue function

This is a bug report for fsmlabs regarding RTLinux3.1 (at least) The semaphore function .. int sem_getvalue(sem_t* sem, int* sval) is supposed to write the semaphore value to the int pointed to by sval, and return an error code. Instead, it doesn't write anything to sval, and returns the

[rtl] Problem using multiple serial ports

Hi there! Using dev/ttyS0 in my program works perfect, but I would like to use /dev/ttyS1, /dev/ttyS2 and /dev/ttyS3 as well. To avoid any trouble, I assigned a different interrupt to each of the four serial pots: ttyS0 4 ttyS1 3 ttyS2 5 ttyS3 7 and I used the usual i/o-addresses. All is

Re: [rtl] communication between modules

No reason to apologize, your English is almost perfect. Anyway, there may be other means, but here are some: 1. Global variables. You can export symbols in the module that's loaded first and have each of the modules put into these variables what it wishes to share and take out what it needs

[rtl] disk write performance question

Hi all. This is a bit peripheral to rtlinux, but hopefully someone here can help me out. I have written a data acquistion application using an rtlinux module, and, while everything works well when I am not saving data to disk, during disk writes I get pauses in the display. This is, as far as I
