( https://review.coreboot.org/c/flashrom/+/84203?usp=email ) Change subject: Fix FEATURE_NO_ERASE chips and add test for them ...................................................................... Patch Set 4: (2 comments) File flashrom.c: https://review.coreboot.org/c/flashrom/+/84203/comment/369f0e75_d38fa01e?us… : PS3, Line 487: for (int i = 0; opcode[i]; i++) { > I would say "chips that don't have erase operation capability, and no erase opcodes"? I don't think it's correct to say that, but we kind of need to *decide* what meaning this has because is only has a few users and none of them are currently well-documented. There are currently only two cases where `FEATURE_NO_ERASE` can be enabled: * `linux_mtd` enables it if the kernel reports `MTD_NO_ERASE`, which is described by a comment as "no erase necessary" * M95M02 EEPROM has it enabled statically For MTD devices, the description seems fairly clear that there may be erase functionality but it doesn't need to be erased before writing. M92M02 doesn't have an erase command, but that's common for EEPROMs because there's usually on reason to do bulk erases. I [found one person claiming some EEPROMs have erase commands](https://forums.anandtech.com/threads/erasing-an-eeprom-chip.13271… but no specific part numbers aside from built-in EEPROMs in microcontrollers which often do have dedicated erase commands. Given these, I think we need to use the same interpretation as Linux does, and make `FEATURE_NO_ERASE` indicate that erase is not required before writing but can still be done (and on some chips erasing may be faster than writing an "erased" value).

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>

[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).
