[pxc] Re: Problem with pxc & RH 7.1

[Alessandro Rubini]

I'm sorry I can't deal with PXC issue for a while. 

When no image is acquired, the problem might be about interrupt setup,
as reported by Chanop Silpa-Anan on Sep 12:

   The driver works on both motherboards, however, I have to set the BIOS
   to MPS 1.1 instead of MPS 1.4 to get the interrupt to happen. e.g. pxc
   driver reports interupt 10 while /proc/pci reports interupt 19 etc....
   , hence, could be the source of the problem I experienced.
   
   FYI, MPS 1.4 will allow virtual interupt, IIRC.

You can check what is happening in /proc/interrupts (while the pxc device
is open), to see if interrupts are received (and what line is used).

In /proc/pci, or /proc/bus/pci/devices you'll find what interrupt does
the device talk on. They should be the same, see above about possible
differnces
