Dear EBBR contributors,
We will have an EBBR call[1] today, Dec 4 at 14h00 UTC.
We have two topics and a pull request on the agenda[2]:
- #135: Prepare for v2.3.0
- HTTP Boot (Ilias)
- Changing SetVirtualAddressMap() + ConvertPointer() to optional and not recommended (Ilias)
This would mean that EBBR firmware is no longer able to boot generic UEFI based operating systems. I would strongly discourage such a change.
If for specific scenarios, e.g. when running current Linux, SetVirtualAddressMap() is not needed, it may be disabled on a project basis but we should not call this EBBR compatible.
Hi Heinrich,
Thank you for your inputs. Ilias will update us on this proposal today hopefully. I understand that you cannot join today, but you will have the minutes and we can have a quick summary next call and continue the discussion by e-mail, too.
On my side I could verify the following aspects: - Those functions are optional at RunTime in UEFI - Linux can boot with and without calling SetVirtualAddressMap(), and AFAICT it never calls ConvertPointer()
I thus wonder if your comment about not being able to boot a generic OS without those is maybe a bit too strong?
Best regards, Vincent.
Best regards
Heinrich
We can use this pad[3] for the meeting notes. Feel free to add to the agenda, directly on the wiki page, by e-mail or on the pad.
