Hi, I'm making this call on my driver's BAR1 which has a physical address 0xf2000008 written on it. So I'm assuming that when I call a hat_getpfnum(kas.a_hat, returned_address), I should get the physical page frame number.
Instead I get 0xffffffff as its return value (which is definitely some error). Also the virtual address that ddi_regs_map_setup is returning 0xc000 as the virtual address for the physical address in the BAR1. Please note that hat_getpfnum returns proper values for other virtual addresses. Can someone help me understand what is going on in my case? Regards, Bhaskar.
