Subject: [PATCH 19/23] mdadm: enable Intel Alderlake RSTe configuration
|
|
Patch-mainline: N/A, SUSE only patch
|
|
References: bsc#1201297
|
|
|
|
Alderlake has a slightly different RST configuration; the UEFI
|
|
variable is name 'RstVmdV', and the AHCI controller shows up as
|
|
a child device of the VMD bridge, but continues to use the 'AHCI HBA'
|
|
PCI class (and not the RAID class as RSTe would normally do).
