The `flashrom.c` kitchen sink should be broken up in any case and given your modular work this is a opportunity to advance that goal forwards at the same time rather than adding to the problem. `erasure_layout.c`, `flashrom_erasure.c`, just `flash_erasure.c` something like that? -- To view, visit https://review.coreboot.org/c/flashrom/+/66104 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-Change-Id: I29e3f2bd796759794184b125741a5abaac6f3ce8 Gerrit-Change-Number: 66104 Gerrit-PatchSet: 76 Gerrit-Owner: Aarya <aarya.chaumal(a)gmail.com> Gerrit-Reviewer: Simon Buhrow Gerrit-Reviewer: Thomas Heijligen <src(a)posteo.de> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-CC: Edward O'Callaghan <quasisec(a)chromium.org> Gerrit-CC: Nico Huber <nico.h(a)gmx.de> Gerrit-CC: Paul Menzel <paulepanter(a)mailbox.org> Gerrit-Attention: Simon Buhrow Gerrit-Attention: Nico Huber <nico.h(a)gmx.de> Gerrit-Attention: Aarya <aarya.chaumal(a)gmail.com> Gerrit-Attention: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Comment-Date: Tue, 13 Dec 2022 23:56:08 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Edward O'Callaghan <quasisec(a)chromium.org> Comment-In-Reply-To: Aarya <aarya.chaumal(a)gmail.com> Gerrit-MessageType: comment

[S] Change in flashrom[1.3.x]: internal.c: laptop_ok global state can become stale
by Anastasia Klimchuk (Code Review) 13 Dec '22

13 Dec '22

Anastasia Klimchuk has submitted this change. ( https://review.coreboot.org/c/flashrom/+/70327 ) Change subject: internal.c: laptop_ok global state can become stale ...................................................................... internal.c: laptop_ok global state can become stale Craask and similar DUT's are erroneously probing random second chips. ``` Found chipset "Intel Alder Lake-N". Enabling flash write... SPI Configuration is locked down. FREG0: Flash Descriptor region (0x00000000-0x00000fff) is read-write. FREG1: BIOS region (0x003a0000-0x00ffffff) is read-write. FREG2: Management Engine region (0x00001000-0x0039ffff) is read-write. OK. Found Winbond flash chip "W25Q128.V..M" (16384 kB, Programmer-specific) on host. Warning: Setting BIOS Control at 0xdc from 0x8b to 0x89 failed. New value is 0x8b. Found MoselVitelic flash chip "V29C51000T" (64 kB, Parallel) mapped at physical address 0x00000000ffff0000. ``` This seems to be due to `laptop_ok` becoming a stale global state after the first operation leading to probing on unrelated buses. Therefore unconditionally reset the global state upon entry into the internal driver. BUG=b:260518132,b:260151917 TEST=Craask reportly no longer finds duplicate chip.
