Author: hailfinger Date: Wed Oct 20 23:13:19 2010 New Revision: 1216 URL: http://flashrom.org/trac/flashrom/changeset/1216 Log: Add a reset to probe_jedec before we read the Chip's IDs. Previous probes might have had too short delays for entering ID mode, so the chip may still be in the process of entering the ID mode. Due to that, an additional delay before the reset makes sense. Add FEATURE_RESET_MASK to deal cleanly with those feature bits. Maciej Pijanka tested the patch and it fixes probing for him with some old Atmel chips.

Those modules > are not present on the linux that doesn't work. Ok, I have the answer. It was iTCO_wdt, not intel_rng as I first guessed. iTCO_wdt clears bit 13 (TCO_EN) of SMI_EN. This is what allows flashrom to enable writing (tested by clearing the bit with a debugger and running DOS flashrom). from iTCO_wdt.c iTCO_wdt_init: /* Bit 13: TCO_EN -> 0 = Disables TCO logic generating an SMI# */ val32 = inl(SMI_EN); val32 &= 0xffffdfff; /* Turn off SMI clearing watchdog */ outl(val32, SMI_EN); Thanks, Dan

Author: hailfinger Date: Wed Oct 20 00:06:20 2010 New Revision: 1215 URL: http://flashrom.org/trac/flashrom/changeset/1215 Log: Always read the flash chip before writing. This will allow flashrom to skip erase of already-erased blocks and to skip write of blocks which already have the wanted contents. Avoid emergency messages by checking if the chip contents after a failed write operation (erase/write) are unchanged. Keep the emergency messages after a failed pure erase. That part is debatable because if someone wants erase, he pretty sure doesn't care about the flash contents anymore. Please note that this introduces additional overhead of a full chip read before write. This is frowned upon by people with slow programmers. A followup patch will make this configurable.

large file support
by Carl-Daniel Hailfinger 19 Oct '10

19 Oct '10

I noticed that chipset_enable.c has #define _LARGEFILE64_SOURCE but it does not perform any open/seek, whereas other files (especially physmap.c) have no indication of large file support, yet they do use open/seek. Looking at the code history this seems to be an accident. What's the correct way to get large file support, and do we need it at all? Image files will probably stay smaller than 16 MB, so I see no real problems there, but MSR support and physmap support may need this. Regards, Carl-Daniel -- http://www.hailfinger.org/

[PATCH] cbtable mapping fix
by Carl-Daniel Hailfinger 19 Oct '10

19 Oct '10

The cbtable code in flashrom is ancient, and although it grew new features over time, it is not exactly one of the most readable pieces of code in flashrom. This is in part due to the complicated integration of the cbtable code in flashrom, and in part due to the way mapping the cbtable has to deal with OS constraints. The goal for cbtable and DMI code is to be well-encapsulated with equal rights for both. I believe the following patch is a bugfix, but I'd love to get a very thorough review for this.
