Hi all,
I'm considering doing a quick point-release for EBBR to address the
change to RuntimeServicesSupported in UEFI 2.8 Errata A. From 2.8final
to 2.8_A, RuntimeServicesSupported changed from being a variable to data
in a system table entry. U-Boot and Linux have been updated to the UEFI
method. EBBR needs to be changed to match.
There are patches on this list under discussion now. Once that is
complete and the patches merged, how does everyone feel about an EBBR
v1.0.1 release before the end of May?
At this moment, the v1.0.1 changes would include:
e47952b (HEAD -> master, glikely/master) Specify details of how a DTB is
passed to the OS
Thanks for updating the patch.
c155e96 Update spec to address UEFI 2.8 Errata A
The patch looks correct. This is what I stumbled upon looking at the
rest of the runtime chapter:
The 'Runtime Variable Access' sub-chapter mentions only SetVariable() as
optional while the table above it specifies all variable services as
optional. Could we start the sub-chapter with a sentence
"All variable services at runtime are optional."
to avoid misunderstandings.
The `RuntimeServicesSupported` value flag in the
`EFI_RT_PROPERTIES_TABLE` should be set correctly for all runtime
services. Mentioning this requirement specifically for SetVariable()
might be misleading.
This is a bit tricky. In past conversations I was pushing toward making
GetVariable()/GetNextVariableName() required and only SetVariable()
optional, but there wasn't concensus at that time. The text as it stands
it kind of a mix on whether or not GetVariable() is required or merely
recommended.
For the point release that we do soon, I could tidy up the text a bit,
but I'd like some thoughts on where EBBR should go for the next major
revision. GetVariable() should be straight forward to implement
GetVariable at runtime by using a RAM-cached value. I don't believe any
work has been done to support that in U-Boot.
Thoughts?
There is a capitalization typo in the chapter:
%s/e.g., If/E.g., if/
Fixed and committed as a trivial fix.
