CB:50246 is not supposed to change behavior and I assume your current version wouldn't work without that patch. Building hacks on hacks is exactly why we need a bug tracker now. Maybe worth to share: When Edward started to push chromium code, I said sometimes it can save a lot of time to ignore the existing implementation, find the requirements and implement it from scratch instead. I made exactly that experience before when I tried to port things from chromium myself. I think it's the same with code on our master branch today. If I wanted to implement this, I'd probably checkout v1.2, implement what is needed and then port it forward. The master branch was in a better state to add new things back then. Anyway, you already made much progress, so I think such a stunt is not necessary. The only obstacle I see left is the usage of the spi read/ write/erase functions. So how about you try one version without them, i.e. memcpy()/memset() instead. Hmmm, looking at emulate_spi_chip_ response(), also setting `emu_modified` in case but that seems to be all to do. And then let the customer team test that? If it works, there is no need to discuss hacks. -- To view, visit https://review.coreboot.org/c/flashrom/+/64488 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-Change-Id: I76402bfdf8b1a75489e4509fec92c9a777d0cf58 Gerrit-Change-Number: 64488 Gerrit-PatchSet: 2 Gerrit-Owner: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Reviewer: Edward O'Callaghan <quasisec(a)chromium.org> Gerrit-Reviewer: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Reviewer: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Reviewer: Thomas Heijligen <src(a)posteo.de> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Angel Pons <th3fanbus(a)gmail.com> Gerrit-CC: Felix Singer <felixsinger(a)posteo.net> Gerrit-CC: Namyoon Woo <namyoon(a)google.com> Gerrit-CC: Nico Huber <nico.h(a)gmx.de> Gerrit-Attention: Thomas Heijligen <src(a)posteo.de> Gerrit-Attention: Edward O'Callaghan <quasisec(a)chromium.org> Gerrit-Attention: Angel Pons <th3fanbus(a)gmail.com> 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: Fri, 20 May 2022 15:24:42 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Nico Huber <nico.h(a)gmx.de> Comment-In-Reply-To: Angel Pons <th3fanbus(a)gmail.com> Comment-In-Reply-To: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-MessageType: comment

I should have done from the very beginning... I discovered that for spi infra flashctx is const and the only way the feature works is because `probe_variable_size` is linked at the very high level, directly into the chip. I did few attempts to wire the feature via spi infra, but I couldn't because spi assumes flashctx is const. https://review.coreboot.org/c/flashrom/+/64488/comment/8f591e84_129c56d5 PS1, Line 153: for (i = 0; i < NUM_ERASEFUNCTIONS; i++) { > There is only one by definition (opaque entry in flashchips.c).

However they call the same functions: default_spi_read, dummy_spi_write_256, spi_block_erase_c7. The reason is that I wanted to keep the behaviour. But this also depends on spi vs opaque conversation. https://review.coreboot.org/c/flashrom/+/64488/comment/8a642a7e_23b28025 PS1, Line 1269: rmst.spi = *s_mst; : rmst.opaque = *o_mst; > It's not supposed to work like this. Yes I admit this is a hack! :) I thought this is an improvement from current situation because it fixes the build with CONFIG_DUMMY=no, and also now hack is contained in dummy and not splashed around the code. I continue thinking if there is better solution, but I decided to send this patch so that we can discuss. I also wanted to explain why this double master is needed. First my attempt was to wire the feature as a spi master, but I couldn't make it compile: because spi infra expects flashctx to be const. Then I started trying to wire as opaque master, as only opaque (not double). Probing was working nicely, but read/write did not work. The problem was that functions in spi.c and spi25.c they all expect `flash->mst->spi` to be present. And I wanted to call all the same functions for read / write (the same as now). I mean right now read/write will go to dummy_spi_send_command, and I didn't want to re-write it. This is how I got to double master. It is really an opaque master, but also it has `flash->mst->spi` available. And as the end result, dummy is using opaque chip and spi send commands. So... do you think it's too bad? :) I don't have another ideas at the moment :\ I can see this needs to be wired as opaque master, that's for sure. But also I don't want to re-write existing dummy_spi_send_command... -- To view, visit https://review.coreboot.org/c/flashrom/+/64488 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-Change-Id: I76402bfdf8b1a75489e4509fec92c9a777d0cf58 Gerrit-Change-Number: 64488 Gerrit-PatchSet: 2 Gerrit-Owner: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Reviewer: Edward O'Callaghan <quasisec(a)chromium.org> Gerrit-Reviewer: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Reviewer: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Reviewer: Thomas Heijligen <src(a)posteo.de> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Felix Singer <felixsinger(a)posteo.net> Gerrit-CC: Namyoon Woo <namyoon(a)google.com> Gerrit-CC: Nico Huber <nico.h(a)gmx.de> Gerrit-Attention: Nico Huber <nico.h(a)gmx.de> Gerrit-Attention: Thomas Heijligen <src(a)posteo.de> Gerrit-Attention: Edward O'Callaghan <quasisec(a)chromium.org> Gerrit-Attention: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Attention: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Comment-Date: Fri, 20 May 2022 06:40:47 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Nico Huber <nico.h(a)gmx.de> Gerrit-MessageType: comment
