The Pg.i830 and interrupt usage   
Hi,

here is what I get when I type "sin irqs" command on the same machine, but:

1) with the latest Pg.i830 driver:
...
  9    27  //1/bin/Dev32.ser        0005:001657 000D
 11    85  //1/*/drivers/Pg.i830    0005:008870 000D
 12    90  //1/bin/Input            0005:01436F 000D
 13     1  /boot/sys/Proc32         00F0:004CD7 00F8
...  

2) with a prevoius release of the Pg.i830 driver:
...
  9    27  //1/bin/Dev32.ser        0005:001657 000D
 12    90  //1/bin/Input            0005:01436F 000D
 13     1  /boot/sys/Proc32         00F0:004CD7 00F8
...  

As we see in the second case graphics driver is not on IRQ's list.
Is there any difference in driver operation, performance, etc. ?

Regards,
Jacek

Hi Jacek,

Yes, interrupts aren't used in the new i830 driver.

Hi Oleg,

So, doesn't matter if I enable or disable interrupt for display controller ?

Regards,
Jacek

Hi Jacek,

There is no difference with current driver.
