Hi Eitan,
I know the root cause for this issue now. The parent bridge is also
re-programed in pci_autoconfig, but is just assigned with 1M MEM space
by default which is less than the requesting 8M MEM size from child
[4/0/0]. So [4/0/0] is failed to be reprogrammed.

I'll sent you a binary to try and file CR accordingly. Stay tuned.

I don't know why the scanpci names these bars as BAR2 and 4.
Attached is the full output of the scanpci command. It looks like one of
the BARs is missing (BAR0 with size of 0x7fffff). BASE4 is the MSI-X
vector.

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.

Kerry

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
