[pso] tema 2 linux dev_id

[Luis Cazacu]

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
