Title:
[FFe] Add Intel RAID/RST detection with NVMe devices
Status in ubiquity package in Ubuntu:
Triaged
Bug description:
[Impact]
A new discover-remapped-nvme.sh supports to detect if Intel RAID/RST
mode is activated as NVMe devices are remapped to AHCI memory space.
Based on this, ubiquity installer can take advantage of detection and
handle such a case with improved user experience.
[Test Case]
There are several ways to test this case, but one of them will be
integration test:
In ubiquity, hw-detect will be sourced, and then ubi-partman executes
discover-remapped-nvme.sh to call remapped_nvme_probe(). Then use
db.get('disk-detect/activate_remapped_nvme') to get boolean value.
To verify value can be issuing debconf command:
$ echo "get disk-detect/activate_remapped_nvme" | sudo debconf-communicate
0 True
[Regression Potential]
Some case will be different, especially the system doesn't have AHCI
when RAID mode was set in BIOS, so that PCI attribute "remapped_nvme"
is gone.
[Other Info]
To upstream to debian sid is another WIP item.
