Doing fixes > and simple changes like this in advance works well, FWIW. +1 For me, it's very easy to miss something when reviewing commits that do multiple things at once. I'd rather review multiple commits where each does one and only one thing. Whenever I want/need to make significant code changes, I draft in advance a "plan of action". I use several criteria to segment the changes into commits, one of them is "at most one thing/reason/idea per commit". In this case, "simplify `pony_spi` init logic" and "use `bool` type for boolean variables" are two different things, and they are conceptually independent: disregarding merge conflicts, it's possible to do them in either order, or only do one of them. When accounting for merge conflicts, I start with the easiest (most likely to be approved) commits, so that I don't have to manually rebase them if another commit needs to be fixed. That being said, there's no need to over-split things. For example, I'd retype both `have_device` and `have_prog` in the same commit, because the rationale is the same. TL;DR: Please retype the variables in a separate commit (preferably before the "extract `get_params`" commit to streamline the submission process). https://review.coreboot.org/c/flashrom/+/63130/comment/523207c5_d0f3c3b6 PS3, Line 171: return 1; If the `dev` parameter is correct (i.e. `have_device` is true) but `get_params()` returns -1 because of an error with the `type` parameter, the serial port (what `serialport_shutdown()` releases) will leak. https://review.coreboot.org/c/flashrom/+/63130/comment/3b064e8c_49fe92dc PS3, Line 181: return 1; Serial port can also leak here. https://review.coreboot.org/c/flashrom/+/63130/comment/229d3eda_23804449 PS3, Line 190: serialport_shutdown > I think you are mis-interpreting the diff presented by gerrit Anastasia.

OK, I picked to follow pch300 in `prettyprint_ich_descriptor_master()` and fixed that up. `ich_number_of_masters()` was left untouched. I wonder how much of this declarative information about the differences could be encoded into just a big table instead of scattered over heaps of switch statements in the control flow itself?

Is there a solid technical reason here or just personal preference? From my point of view: Review doesn't scale well with the size of a patch. Even if it's a very simple patch hunk, every additional hunk can distract from the error-prone part of a patch. Doing fixes and simple changes like this in advance works well, FWIW. -- To view, visit https://review.coreboot.org/c/flashrom/+/63130 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-Change-Id: I364febc05c870683cbad114583762b0c006f4bac Gerrit-Change-Number: 63130 Gerrit-PatchSet: 3 Gerrit-Owner: Edward O'Callaghan <quasisec(a)chromium.org> Gerrit-Reviewer: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Reviewer: Light <aarya.chaumal(a)gmail.com> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Felix Singer <felixsinger(a)posteo.net> Gerrit-CC: Nico Huber <nico.h(a)gmx.de> Gerrit-Attention: Edward O'Callaghan <quasisec(a)chromium.org> Gerrit-Attention: Light <aarya.chaumal(a)gmail.com> Gerrit-Attention: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Comment-Date: Sat, 02 Apr 2022 14:19:45 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Edward O'Callaghan <quasisec(a)chromium.org> Comment-In-Reply-To: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-MessageType: comment

Change in flashrom[master]: flashrom.c: Implement file-based locking semantics
by Daniel Campello (Code Review) 02 Apr '22

02 Apr '22

Attention is currently required from: Hung-Te Lin, Nico Huber, Subrata Banik, Edward O'Callaghan. Daniel Campello has uploaded a new patch set (#17) to the change originally created by Edward O'Callaghan. ( https://review.coreboot.org/c/flashrom/+/62213 ) Change subject: flashrom.c: Implement file-based locking semantics ...................................................................... flashrom.c: Implement file-based locking semantics This upstreams the ChromiumOS implementation of file-based locking for multiple instances of flashrom that could be spawned either from libflashrom (perhaps by fwupd for example) and user cli as another example. Since flashrom is programming singleton state of hardware from userspace there is no way to exclusively own the address space and therefore a file-based locking semantic is considered here. BUG=b:217629892,b:215255210 BRANCH=none TEST=nm -gD /build/brya/usr/lib64/libflashrom.so | grep "flock" Test futility update with multiple instances of flashrom running.
