mkdaxfs fails to create daxfs at specified physical RAM address

[haironghu]

When executing the command mkdaxfs -d /path/to/rootfs -p 0x100000000 -s 256M to create a daxfs instance at the free system physical memory address 0x100000000 and 0x61e80000000, the operation fails without generating the expected daxfs.

The specific execution results are as follows:

System Environment:
Kernel version: uname -r → 6.6.0-98.0.0.103.oe2403sp2.x86_64
Operating System: openEuler 24.03 (LTS-SP2)

Could you help troubleshoot the cause of the failure and the correct way to specify the physical address? Thanks! @congwang-mk

Hi @haironghu

The branching support has been removed from DAXFS (If you want to try branching, please use BranchFS https://github.com/multikernel/branchfs). Could you try the latest code?

Thanks for testing.
