not true on old PCI based controllers. DAC configuration is read from EEPROM in device reset phase and driver can override DAC configuration. However I guess there is an undocumented reason why EEPROM configuration does not enable DAC so do not blindly override DAC configuration. Recent PCIe based controllers are supposed to support 64bit DMA so allow 64bit DMA only on PCIe based controllers. PR: kern/157184 MFC after: 1 week |
