Google Panther: coreboot has to wait for Intel’s ME (Management Engine)

by Paul Menzel

Dear coreboot folks, looking at the time stamps of the Intel Haswell device Google Panther, which Matt DeVillier thankfully uploaded to the board status repository [1], it looks odd that it took around a quarter of a second, from after the SeaBIOS payload was decompressed to starting the payload. This is almost half of the whole boot time. […] 90:load payload 233,302 (216) 15:starting LZMA decompress (ignore for x86) 233,415 (113) 16:finished LZMA decompress (ignore for x86) 250,327 (16,912) 99:selfboot jump 493,712 (243,384) Thanks to Aaron Durbin’s analysis of the code path, the finalize in line 138 of `src/southbridge/intel/lynxpoint/smi.c` calls `intel_me_mbp_clear()` in line 589 of `src/southbridge/intel/lynxpoint/me_9.x.c`. $ more src/southbridge/intel/lynxpoint/me_9.x.c # line 589 […] #if CONFIG_ME_MBP_CLEAR_LATE /* Wait for ME MBP Cleared indicator */ intel_me_mbp_clear(PCH_ME_DEV); #endif […] The issue is even described in the Kconfig option description of `ME_MBP_CLEAR_LATE` and the commit message of commit 3d299c4b (lynxpoint me: add support for mbp clear wait in finalize step) [2] adding this option. $ more src/southbridge/intel/lynxpoint/Kconfig […] config ME_MBP_CLEAR_LATE bool "Defer wait for ME MBP Cleared" default y help If you set this option to y, the Management Engine driver will defer waiting for the MBP Cleared indicator until the finalize step. This can speed up boot time if the ME takes a long time to indicate this status. […] I guess there is no way to get fixed ME BLOBs from Intel. I heard the ME BLOB has been fixed for newer Intel devices. Thanks, Paul [1] http://review.coreboot.org/gitweb?p=board-status.git;a=commitdiff;h=3926f95… [2] http://review.coreboot.org/4375

Re: [coreboot] Regarding Intel (and Librem)

by Vladimir

Today I discovered that CPU is indeed socket-ed on G505s, so it is possible to get G505s with less powerful CPU (e.g. A8) , and - if it turns out to be not compatible, or not fast enough for your needs, then you could get A10-5750M and install by yourself. Saw it for ~$50-$80 at Aliexpress (higher price for not used yet) There are three slightly different motherboards which could be found in Lenovo G505s, all made by Compal Electronics : *1) *LA-A092P for only 8650G, which is built-in into APU (no dual graphics) *2)* LA-A091P rev 1.0 for 8650G + AMD HD 8570M (dual graphics) *3)* LA-A091P rev 1.A for 8650G + AMD R5 M230 ( dual graphics, slightly more powerful than "2)" ) And, some other Lenovo laptops have the same Compal motherboards, e.g. G405s has LA-A091P. If I am correct: there are more Lenovo AMD laptops supported by Coreboot, they are just not tested yet... Also, on my motherboard there was no MXIC chip, but cFeon QH32-104HIP bios chip instead. As you see, lots of things could be added to Coreboot G505s wiki. I've asked a coreboot wiki account so that I could improve g505s page: add new information, and clarify older as well On 17 April 2015 at 11:45, Vladimir <quickcracktime(a)gmail.com> wrote: > Problem with Librem is not just that it isn't fully free yet and doesn't > seem to become so in future, but also that it is an Intel-based product. > > Intel is totally NOT friendly to coreboot project (and open source > community in general) - that could be seen by their malevolent actions, > such as introduction of Boot Guard "feature".

toolchain for building mips targets

by Vadim Bendebury

guys, how do you set up toolchain for building mips targets (or rather mips target, as there is just one currently :). I got this flavor from Mentor Graphics site: mips-linux-gnu-gcc (Sourcery CodeBench Lite 2014.05-27) 4.8.3 20140320 (prerelease) Copyright (C) 2013 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. the thing is that it requires a command line option to generate little endian object files (-EL), but xcompile does not provide one and as a result fails to accept this toolchain as valid. BTW, this is how I invoke xcompile for the purposes of this experiment: CROSS_COMPILE=mips-linux-gnu- util/xcompile/xcompile TIA, -vb

On Intel Boot Guard

by Iru Cai

Hi, I've just seen a forum thread about removing the white list of ThinkPad X240, so I think Boot Guard is not preventing modification of BIOS. Then I read some article, which says what Boot Guard locks is the boot block, so I think there's still some way to flash coreboot on a new Intel platform.

gerrit authentication

Hi, To provide more options to contributors, it's now possible to login to our code review system at http://review.coreboot.org using GitHub credentials. On the login screen, simply pick 'GitHub OAuth2'. If you already have an account, you can link your GitHub account to it by logging in on gerrit, clicking 'Link Another Identity' on http://review.coreboot.org/#/settings/web-identities, and selecting GitHub OAuth2 (and acknowleding on GitHub that you want to associate your account with coreboot code review). Of course, OpenID still works, as does logging in using Google Accounts through OAuth2.
