[rtl] Maximum RT-FIFO size and lost data on RT_interrupt
Dear All,
I have one experience on implementation RT-Linux by employing Interrupt
Request 7 on EPP/LPT port, and one FIFO with size 8192 bytes. But, some
times there are many data lost, it seem caused by n-th interrupt can not
process by CPU , some times on 200th IRQ, 240th IRQ, 600th IRQ, etc .
For information, the data stream speed is 40 kbytes/s and running on
Pentium 120.
* Why many interrupt are lost on my program RT-Linux ?
* How many bytes the maximum FIFO on RT-Linux ?
I don't know what is wrong in my code.
Sincerely Yours,
