[edk2-devel] [PATCH] SecurityPkg/OpalPassword: Remove dependency on EFI_BLOCK_IO_PROTOCOL

Posted by Maggie Chu 2 weeks ago
https://bugzilla.tianocore.org/show_bug.cgi?id=2327

RAID drivers abstract their physical drives that make up
the array into a single unit, and do not supply individual
EFI_BLOCK_IO_PROTOCOL instances for each physical drive in the array.
This breaks support for the Security Storage Command Protocol,
which currently requires an EFI_BLOCK_IO_PROTOCOL to be associated
with the same device the protocol is installed on and provide
all the same parameters.

This patch remove dependency on EFI_BLOCK_IO_PROTOCOL and
allows access to Opal drive members of a RAID array.

Re: [edk2-devel] [PATCH] SecurityPkg/OpalPassword: Remove dependency on EFI_BLOCK_IO_PROTOCOL

Posted by Maggie Chu 2 weeks ago
Hi Jiewen,

This patch has been added to client bios as override since last year and validated on WHL/CFL/ICL and also CML.
It was asked by RST team because BLOCK IO protocol is unable to be provided on each physical device when RAID volume created.

Thanks,
Maggie
