God Yes exactly my missing link, Thanks. How I failed to find it?
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
