( https://review.coreboot.org/c/flashrom/+/84203?usp=email ) Change subject: Fix FEATURE_NO_ERASE chips and add test for them ...................................................................... Patch Set 4: (1 comment) File flashrom.c: https://review.coreboot.org/c/flashrom/+/84203/comment/db3d63e0_6e7fe218?us… : PS3, Line 487: for (int i = 0; opcode[i]; i++) { > This will always crash if spi_get_opcode_from_erasefn doesn't know the eraser, which should probably be fixed to gracefully bail out. 100% yes, I added a check for null. There are 22 opcodes known to `spi_get_opcode_from_erasefn` and 34 erase functions known to `lookup_erase_func_ptr` ! oh :( yes, we need to check for null. About `FEATURE_NO_ERASE`, I thought those are chips that don't have any erase opcodes, and they just don't support erase operation at all - whether it's erase-before-write or just erase, doesn't matter. The way the feature is implemented is that when such a chip is asked to be erased, the special `SPI_BLOCK_ERASE_EMULATION` is quietly doing write instead of erase, and the end result for the chip memory is the same. So, I added a check for null, but haven't added any comment to FEATURE_NO_ERASE yet. If I would be adding a comment, I would say "chips that don't have erase operation capability, and no erase opcodes"? -- To view, visit https://review.coreboot.org/c/flashrom/+/84203?usp=email To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings?usp=email Gerrit-MessageType: comment Gerrit-Project: flashrom Gerrit-Branch: main Gerrit-Change-Id: I582fe00da0715e9b5e92fcc9d15d5a90a2615117 Gerrit-Change-Number: 84203 Gerrit-PatchSet: 4 Gerrit-Owner: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Reviewer: Miklós Márton <martonmiklosqdev(a)gmail.com> Gerrit-Reviewer: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-Attention: Miklós Márton <martonmiklosqdev(a)gmail.com> Gerrit-Attention: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Comment-Date: Tue, 10 Sep 2024 11:44:44 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Peter Marheine <pmarheine(a)chromium.org>

Attention is currently required from: Anastasia Klimchuk, Miklós Márton. Hello Miklós Márton, Peter Marheine, build bot (Jenkins), I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/flashrom/+/84203?usp=email to look at the new patch set (#4). The following approvals got outdated and were removed: Verified+1 by build bot (Jenkins) Change subject: Fix FEATURE_NO_ERASE chips and add test for them ...................................................................... Fix FEATURE_NO_ERASE chips and add test for them New check was added to `check_block_eraser` in commit 0f389aea9e630c3b21547a5dd8dbe572a8502853 but it was not handling FEATURE_NO_ERASE chips. This patch fixes processing such chips and adds test to run write and verify with dummyflasher for FEATURE_NO_ERASE chips.

[S] Change in flashrom[main]: ichspi: Restore Sector erase opcode after send command

[M] Change in flashrom[main]: Ensure verify operation completed in full if chip memory modified
by Anastasia Klimchuk (Code Review) 08 Sep '24

08 Sep '24

Anastasia Klimchuk has submitted this change. ( https://review.coreboot.org/c/flashrom/+/84078?usp=email ) Change subject: Ensure verify operation completed in full if chip memory modified ...................................................................... Ensure verify operation completed in full if chip memory modified The patch adds new functionality to the test: tracking the areas of chip memory that were modified (i.e. by erase or write operation), and then checking those areas were completely covered by verify operation. The test operates over the mock chip memory of 16 bytes, so it is possible to track each byte which was modified, and assert that is has been verified afterwards. Adding the test found a bug which is fixed in this commit: Post-cleanup after processing unaligned region for the case when end region needs to be extended to align with erase block. Writing was done correctly, but post-processing of newcontents could cause one-off offset at the end of the region, which would make verification appear false-negative (see test cases #16-19).
