Cannot disambiguate between multiple questions with the same name

[lwfitzgerald]

Hi,

I'm trying to use uefisettings to flip the Multi-VC (Enable/Disable Multiple Virtual Channel) option in my UEFI's settings, but because this option is present for each PCI-e root port (up to 3), the question appears three times with an identical name:

sudo ./uefisettings hii list-questions | grep -B 1 -A7 'Multi-VC'

    Question {
        name: "Multi-VC",
        answer: "Enabled",
        options: [
            "Disabled",
            "Enabled",
        ],
        help: "Enable/Disable Multi Virtual Channel",
    },
--
    Question {
        name: "Multi-VC",
        answer: "Disabled",
        options: [
            "Disabled",
            "Enabled",
        ],
        help: "Enable/Disable Multi Virtual Channel",
    },
--
    Question {
        name: "Multi-VC",
        answer: "Disabled",
        options: [
            "Disabled",
            "Enabled",
        ],
        help: "Enable/Disable Multi Virtual Channel",
    },

When I try to use uefisettings hii get, only the first question is returned (note only the first is Enabled):

sudo ./uefisettings hii get 'Multi-VC'

GetResponseList {
    responses: [
        GetResponse {
            selector: "899407D7-99FE-43D8-9A21-79EC328CAC21",
            backend: Backend::Hii,
            question: Question {
                name: "Multi-VC",
                answer: "Enabled",
                options: [
                    "Disabled",
                    "Enabled",
                ],
                help: "Enable/Disable Multi Virtual Channel",
            },
            is_translated: false,
        },
    ],
}

Is there any way to select the question to get/set more granularly such that I can choose the other questions?

Thanks in advance, Luke

Hello. Sorry for missing your question.

Is there any way to select the question to get/set more granularly such that I can choose the other questions?

As far as I remember, there are no such capability yet. As a workaround for get-ting, I can suggest only to use list-questions with flag -j (to get a JSON output) and use jq to filter the response. And there is no workaround for set-ting.

Pull Requests are welcomed, though :)

I can explain what needs to be done. I can also explain how to correctly interpret deactivated/grayed-out questions (to make them not appear in the lists; as it should be). But I don't have time to fix this myself in this year :(

Another (hopefully temporary) workaround could be: you can download the tool provided the vendor of you motherboard. For example, very often the proprietary variant of the tool for that is SCELNX: it does allow you make a full dump of all questions with answers, modify it, and upload back.

And one more workaround: you may change the values manually, using dd. If you are interested about this option, please let me know, I'll try to make an example how to do that.

i was the original hiitool author - iirc what we did there was have set optionally accept the name of the Form the question occurred in (though the Form names are not necessarily unique either)

@apage43 : IIRC, hiitool also suffered from inability to distinguish duplicate questions. So, we added the support of filtering by "grayed-out"/inactive. In our practice it was a very rare case when we needed that, so this feature was not ported to uefisettings. Feel free to reach out to me directly, I can find the code change.
