![Francisco Jerez](/assets/img/avatar_default.png)
BIOS scripts usually make an attempt to reset the AGP controller, however on some nv4x cards doing it properly involves switching FW off and on: if we do that without updating the AGP bridge settings accordingly (e.g. with the corresponding calls to agp_enable()) we will be locking ourselves out of the card MMIO space. Do it from nouveau_mem_reset_agp() before the init scripts are executed. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
