Yes for us too, BIOS doesn't zero DRAM and we can use it with using memmap= on kernel boot. Please include above link in new patchset and Documentation. Just to make the overall picture clearer. BTW what prevents from submitting this prd driver upstream right now? there are devices out there that will need it no? Even for something simple and very smart as putting my ext4 or xfs journal device on nv-dimm, no? The "manually address range to use" is fine in my book. A user-mode udev rule can then be used to cover the gap from sbus or acpi to prd. Hey actually this tree has everything I need. thanks man Boaz -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
