Patch Set 6: (1 comment) File flashchips.c: https://review.coreboot.org/c/flashrom/+/81563/comment/169a9945_cede384b : PS3, Line 9523: 1024B > I found it is "4K-bit secured OTP" in datasheet, so maybe twice less? Daniel, I noticed on this patch (and few others that you currently have under review), you left unresolved comments, why? I see that you fixed what the comment was asking, but did not resolve comment as Done. For the reviewers (me, in this case), resolving comment as Done indicates that you are happy with the latest version of your patch, and reviewers can have another look. If the comment is not resolved as Done, reviewers are not sure, maybe you are still working on the patch, or testing it, so it's not ready yet. If this patch is ready (and same for the others), you need to click Done on each comment. And then you need to Reply to the patch, there is a button on the top. Then you click Send, and after that all reviewers get an email, and this is an indication that the patch is ready.

[XS] Change in flashrom[main]: flashrom: Don't throw around "delay 1 second" so lightly
by Anastasia Klimchuk (Code Review) 23 Apr '24

Attention is currently required from: Brian Norris, Nikolai Artemiev, Peter Marheine. Anastasia Klimchuk has posted comments on this change. ( https://review.coreboot.org/c/flashrom/+/80807?usp=email ) Change subject: flashrom: Don't throw around "delay 1 second" so lightly ...................................................................... Patch Set 3: (1 comment) Patchset: PS1: I just thought of something and decided to check... Erase operation verifies the chip straight away after erasing. Without any delay. (Also without respecting the noverify flags, but this we will fix later). From the chip point of view, erase is almost the same as write, is that correct? So maybe the erase flow is kind of a "proof-of-concept" for what this patch is doing? I completely forgot that write and verify can be separated in a manual workflow, so silly of me. This changes the situation, maybe we don't need a special option. > do you want me to start such a mailing list thread, or were you suggesting I do this? Brian, you gave me two options which are the same :) But I agree with both of them. I think you should start the thread. This was your idea, your work and you even went through 10yr old commit messages! Add a link to the patch in the post, so that anyone who is interested can easily click. -- To view, visit https://review.coreboot.org/c/flashrom/+/80807?usp=email To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: main Gerrit-Change-Id: Ie09651fede3f9f03425244c94a2da8bae00315fc Gerrit-Change-Number: 80807 Gerrit-PatchSet: 3 Gerrit-Owner: Brian Norris <briannorris(a)chromium.org> Gerrit-Reviewer: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-CC: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Attention: Brian Norris <briannorris(a)chromium.org> Gerrit-Attention: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Attention: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Comment-Date: Tue, 23 Apr 2024 09:10:19 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Brian Norris <briannorris(a)chromium.org> Comment-In-Reply-To: Nikolai Artemiev <nartemiev(a)google.com> Comment-In-Reply-To: Anastasia Klimchuk <aklm(a)chromium.org> Comment-In-Reply-To: Peter Marheine <pmarheine(a)chromium.org> Gerrit-MessageType: comment

[…] I'd avoid adding a flag - if there really are chips that need a delay, then there is a hardware or software bug that should be addressed with a chip flag or driver fix instead. Adding a flag makes a temporary fix more permanent. If users need to flash a buggy chip and can't wait for a new flashrom version that fixes it, they can always separate the write & verify operations as Brian suggests. A mailing list post seems like a good option for trying to recover the history around why the delay was added. If we don't get any response there within say 1 week, then I think we should just land this patch. -- To view, visit https://review.coreboot.org/c/flashrom/+/80807?usp=email To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: main Gerrit-Change-Id: Ie09651fede3f9f03425244c94a2da8bae00315fc Gerrit-Change-Number: 80807 Gerrit-PatchSet: 3 Gerrit-Owner: Brian Norris <briannorris(a)chromium.org> Gerrit-Reviewer: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-CC: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Attention: Brian Norris <briannorris(a)chromium.org> Gerrit-Attention: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Attention: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Comment-Date: Tue, 23 Apr 2024 02:56:48 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Brian Norris <briannorris(a)chromium.org> Comment-In-Reply-To: Anastasia Klimchuk <aklm(a)chromium.org> Comment-In-Reply-To: Nikolai Artemiev <nartemiev(a)google.com> Comment-In-Reply-To: Peter Marheine <pmarheine(a)chromium.org> Gerrit-MessageType: comment

[…] Unfortunately, this hack survived so long it migrated from the CLI to the library. So a CLI flag won't really provide an escape hatch for all users -- unless you also want to also add a libflashrom flag for it?? I'm still somewhat of a lazy opinion here: 1. I doubt that anything will come of either this CL, nor of a CLI flag that provides a bug-report-escape-hatch for it and 2. the whole `--verify` sequence is trivial enough to emulate on one's own [1]. That gets slightly more complex to implement if people are using environments without basic stuff like a decent shell or tools like `cmp`, or if they're using surgical flags (like `--include`). But it's not that hard. And the good news is we don't have to try #2 if I'm right about #1 😊 But if you still think we need a flag, I can give it a shot. And either way, do you want me to start such a mailing list thread, or were you suggesting I do this? [1] e.g., `flashrom --read /tmp/foo.bin`; `flashrom --write /my/new/image.bin --noverify`; `sleep 1`; `flashrom --read /tmp/bar.bin`; `cmp /tmp/foo.bin /tmp/bar.bin` -- To view, visit https://review.coreboot.org/c/flashrom/+/80807?usp=email To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: main Gerrit-Change-Id: Ie09651fede3f9f03425244c94a2da8bae00315fc Gerrit-Change-Number: 80807 Gerrit-PatchSet: 3 Gerrit-Owner: Brian Norris <briannorris(a)chromium.org> Gerrit-Reviewer: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-CC: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Attention: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Attention: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Attention: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Comment-Date: Tue, 23 Apr 2024 00:23:30 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Brian Norris <briannorris(a)chromium.org> Comment-In-Reply-To: Anastasia Klimchuk <aklm(a)chromium.org> Comment-In-Reply-To: Nikolai Artemiev <nartemiev(a)google.com> Comment-In-Reply-To: Peter Marheine <pmarheine(a)chromium.org> Gerrit-MessageType: comment

Patch Set 3: (1 comment) Patchset: PS1: > If nobody knows why this is necessary or how to reproduce, I think it's okay to remove. Yes, true. I was trying to find out which exactly chips needed that extra delay, but no success so far. If we knew which chips we could add a feature flag as Nikolai suggested, and mark them in flashchips. But it seems, we don't know. So your plan looks very reasonable: an option will cover for the edge cases (if they exist). I was thinking to start from a post on a mailing list, very specifically about removing 1s delay (there has been none dedicated thread), so that if someone suddenly recalls information about those odd chips, they can share. Even if no one responds, it stays in archives as a record of decision being made with explanation why. And then update this patch with an option, post link to patch to the thread. That should be enough for the "paperwork" :) -- To view, visit https://review.coreboot.org/c/flashrom/+/80807?usp=email To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: main Gerrit-Change-Id: Ie09651fede3f9f03425244c94a2da8bae00315fc Gerrit-Change-Number: 80807 Gerrit-PatchSet: 3 Gerrit-Owner: Brian Norris <briannorris(a)chromium.org> Gerrit-Reviewer: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-CC: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Attention: Brian Norris <briannorris(a)chromium.org> Gerrit-Attention: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Attention: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Comment-Date: Mon, 22 Apr 2024 11:03:24 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Brian Norris <briannorris(a)chromium.org> Comment-In-Reply-To: Anastasia Klimchuk <aklm(a)chromium.org> Comment-In-Reply-To: Nikolai Artemiev <nartemiev(a)google.com> Comment-In-Reply-To: Peter Marheine <pmarheine(a)chromium.org> Gerrit-MessageType: comment

Patch Set 1: (1 comment) Patchset: PS1: Victor, this is amazing, thank you so much for adding and updating so many chips! What you need to do now, is to split this large patch into several smaller ones. I can see some of the models are related and can be grouped together. So for example, GD25LB128E, GD25LQ128E, GD25LR128E can be in one patch. And then GD25LB256F, GD25LQ256H, GD25LR256F can be in the next patch, and so on. When you split your git commit locally, you will have a chain of commits in your local branch. And then when you push the whole chain to Gerrit, you will see all the patches in a chain as well. For commit titles, you can use the pattern: `flashchips: Add (or update) chip models <list models>` Another thing is, you need to provide links to public datasheets for the models added or updated in each patch.
