Hi,

I have attached output from the "show_pci -vvv"  command.

Take a look at the "Device Dependent Registers" part, specially
at the last line:
0xF0: 00 00 00 00 00 00 00 00 68 0f 03 00 8e 1f 00 00 

It seems that show_pci allways returns 0x8e and 0x1f value for 0xFC and 0xFD offset and type of device doesn't matter.

Is it done purposely ?
Can anybody explain this ?

Regards,
Jacek

Re: RE: Interpreting "show_pci" output

Hugh,

now is ok.

Is it possible to print info about Device Dependent Registers
starting from 0x0 offset ?

For example if I type -v option at least four times.

Thank's !!
Jacek

RE: RE: Interpreting "show_pci" output

No, the Device Dependent Registers start at offset 0x40 in PCI space.

Re: RE: RE: Interpreting "show_pci" output

I mean to dump whole PCI space (0x0 -- 0xFF), like
   PCI Space Registers:
   0x00:  .....
    ...      .....
   0xF0:  .....


> No, the Device Dependent Registers start at offset 0x40 in PCI space.

No, we are only fixing bugs in QNX4. Any enhancements require an
official request.

Re: RE: RE: RE: Interpreting "show_pci" output

I understand.

There is a source code of the show_pci on the QNX FTP, but this is very old release.

Is there any chance to obtain a recent version ?

Best,
Jacek

Can you also send me the latest pci.h and inttypes.h file ?

Re: RE: RE: RE: RE: RE: Interpreting "show_pci" output

After compilation show_pci fails in showirq () function
on the following line:

if(_CA_PCI_Get_Routing_Options(&cmd, &irq) != PCI_SUCCESS) {
  return;
}

Application is terminated by SIGSEGV at 00D1:0000B0D9.

Do I need to compile show_pci in specific way ?

You need "-T1 -N32k".
