I am relatively new on MIPS architecture.
working on BSP for MIPS R32xx on IDT .
i have a basic question.
1.PCI BAR 1 of my eepro100 card has been initialised with
address 0x18800100 for 64 bytes.
this is a valid PCI IO address as per manual.
2.what i understand is that lower 0 - 512 MB physical is mapped to
0xa000-0000 to 0xb7ff-ffff virtual and also access to this range
3.when i am loading my eepro100 driver , in do_eeprom_cmd() when
it refers the address( ioaddr + SCBeeprom) my kernel panicks with
message "unable to handle kernel paging request at 0xd100010e.
this virtual address is in range 0xa000-0000 to 0xb7ff-ffff.
now my question is what all i have to do so that this access is
passed i mean i get a valid virtual-physical mapping for this
where i need to take care of kseg1 translation in my BSP
