Author: stefanct Date: Fri Sep 16 01:38:14 2011 New Revision: 1442 URL: http://flashrom.org/trac/flashrom/changeset/1442 Log: serprog: add SPI support Adds a new opcode (0x13) that just relays SPI bytes and wires it up to be usable within serprog.c. Checks for mandatory opcodes are moved around and changed a bit, but non-SPI programmers should not be harmed by this patch.

[PATCH] ichspi: add ICH/PCH flash descriptor decoding via FDOC/FDOD
by Stefan Tauner 15 Sep '11

15 Sep '11

based on the work of Matthias 'mazzoo' Wenzel this patch adds pretty printing of those ICH/PCH flash descriptor sections that are cached/mapped by the chipset (and which are therefore reachable via FDOC/FDOD registers). this includes the following: - content section: describes the image and some generic properties (number of sections, offset of sections, PCH/ICH and MCH/PROC strap offsets and lengths) - component section: identify the different SPI flash chips and their capabilities. - region section similarly to a partition table this describes the different regions. the content of FLREG* is derived from this section. - master section defines SPI master (host, ME, GbE) access rights of the individual regions. the content of PR* is derived from this section. this is only a part of the data included in the descriptor. other information can be retrieved from a complete binary dump of the descriptor region only. this patch also adds macros and pretty printing for "Vendor Specific Component Capabilities" registers: there are two of them: lower and upper. they describe the properties of the address space divided by FPBA (which allows to use multiple flash chips or partitions with different properties). the properties of all supported flash chips (together with their RDIDs) are stored in the same format in table in a descriptor section (which is used by the ME apparently). a later patch will use the macros outside of ichspi.c which is the reason why the prettyprinting function and the register bit macros are not defined in ichspi.c but ich_descriptors.h (else they would be moved in the follow-up patch). because this patch relies on (compiler) implementation-specific layouting of bit-fields, it checks for correct layout before taking any action on runtime.

Error Codes for libflashrom (and elsewhere)
by Stefan Tauner 14 Sep '11

14 Sep '11

we need to discuss the introduction and use of generic return values. they are mainly needed for libflashrom's public function, but could (and should) also be used internally whenever it is useful. apart from naming (i.e. different ideas for prefixes. i'll use FL_ below but do not endorse this version more than others) it is very important to agree on the different error cases we want to define explicitly. 0 == FL_OK (no error) is pretty clear, but then the problems start already: should we report a warning as 0 or an error value? if the latter should it be a value of its own (e.g. FL_WARN) or should the different causes of warnings have all their own numbers? my idea would be this: define different warning codes (or just one generic one like below) and put them in the range between FL_OK and FL_ERR, so that it is still easy to ignore them (e.g. if (ret <= FL_ERR) applies to real errors only). then i would like you to look at the current code (and/or http://flashrom.org/Libflashrom) and list useful return values. we are (probably) not limited in the number of return values _technically_, but there should be a use case for more than just one function i.e. it should be somewhat generic and reusable. i'll start with a few very generic examples which i think might be useful and some which i have already used in my ICH descriptor patch: * FL_ERR: generic/unspecified error. the function could not complete its job. the consequences should be at least defined in the documentation, a to-be-later-discussed errno value might have been set. the caller should abort whatever it is trying to do and inform the user. * FL_WARN: similar to the above, but the function completed its job. there might have been some problems like untested devices or code that might lead to severe consequences later, but till return everything works as designed. an example for this could be that an init function is not able to unlock the whole address range. this is a problem and the user should be notified, but it is inside the scope of our error model and might not be a problem at all if the user does not want to access that region anyway. an example of something that clearly requires FL_ERR instead of FL_WARN would be if an init function of an external programmer can not detect the hardware. there is no easily distinguishable border between the two levels, but i think it will be clear from the context of the function what cases should be reported as errors and warnings respectively. * FL_PARAM: a parameter is not in the expected range. this is actually somewhat of a favor to the calling function, because this means it has disregarded a precondition. we are returning this instead of showing undefined behavior. * FL_OOB: (i.e. out of bounds) we had to abort because else we would reach across the bounds of a data structure (e.g. array). * FL_OOM: (i.e. out of memory) one of malloc et al. failed. this is probably not very useful for the caller, but it can easily be distinguished by the callee and so there is no reason to not give it its own code imho. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Re: [flashrom] [PATCH] revamp the warning of failing to set BIOS write enable in enable_flash_ich
by Stefan Tauner 14 Sep '11

14 Sep '11

and if we are at it... shouldn't we tell the user, that writes will most probably fail in cases where we could not enable bios writes? e.g. the dell optiplex in the "It is hard to report a bug...."-thread: BIOS Lock Enable: enabled, BIOS Write Enable: disabled, BIOS_CNTL is 0x2 tried to set 0xdc to 0x3 on ICH8/ICH8R failed (WARNING ONLY) as far as i understand this, an SMI is triggered and in this case the SMM prohibits us from setting the BIOS WE bit, but this may not be always the case. is there a way around it? i don't know enough about SMM to be sure if that's correct. in any case we won't be able to erase/write if the WE bit is not set and we should indicate this clearly to the user imho. what do you think? -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Thanks. Hello Florian! Please upgrade to 0.9.4 (or later) and report back. It will still warn you, but i think it should actually work. Of course the mainboard might need a hack too, but you will be notified of that separately (if writing fails at address 0 and the content of the flash remains unchanged) and we will implement it then. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
