[pso] tema 2 linux dev_id

[Catalin Morosan]

pai primul parametru e irq_no care in cazul tau ar trebui sa fie 3 sau 4.

daca e 3 atunci adresa e 0x2f8 iar daca e 4 adresa e 0x3f8.

Bineinteles, asta se aplica daca ai initializat totul cum trebuie.

In handler-ul pt intrerupere

irqreturn_t my_handler(int irq_no,void *dev_id,struct pt_regs *regs)

putem sa folosim dev_id in loc de serial[0] sau serial [1] ?

unde serial [0] de exemplu este : 


err = request_irq(MY_IRQ1,my_handler,SA_INTERRUPT,"4uart16550",&my_serial[0]);

Si cum am putea afla pt ce COM este intreruperea  (adresa mai exact , adik 0x3f8 sau 0x2f8)  (fara sa citim registrul IIR) ?


Multumesc,

Luis
