I also need the info of other devices, pls sent me the *whole*
result of the "scanpci -v" result. Since [4/0/0] are requesting
8M size MEM space, I want to make sure if such size is available at
its parent bridge or not.
BTW, I saw the device's BASE2/BASE4 are assigned with valid value.
What's the difference between BASE0 and BASE2/BASE4 in the device h/w
spec.
Regards,
Kerry

Hi Kerry,
Yes, Girresh and I dealing with the same issue.
Here is the output for the scanpci command on this device:

Could you post the '/usr/X11/bin/scanpci -v' result? And what is your
device ID?
I saw you mentioned:
WARNING: failed to program mem space [0/31/3] b...@0x10 length 0x100
While Gireesh mentioned:
WARNING: failed to program mem space [4/0/0] b...@0x10 length 0x800000
Are you two talking about same issue or not?
Regards,
Kerry
