[driver-discuss] OpenSOlaris build 110 - problem with ddi_regs_map_setup() on x86

[Kerry Shu]

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] BAR at 0x10 length 0x100
While Gireesh mentioned:
   WARNING: failed to program mem space [4/0/0] BAR at 0x10 length 0x800000

Are you two talking about same issue or not?

Regards,
Kerry
