With this tool you can read SMC keys. It supports various data types and can output result in various formats. Example how to get battery capacity level: smctool -k B0FC -t ui16 # returns Full Capacity of Battery 0 smctool -k B0RM -t ui16 # returns Remaining Capacity of Batery 0 So B0RM / B0FC * 100 = battery capacity in percents. Another example, reading current fan speed, which is returned as unsigned fixed point number: sudo ./smctool -k F0Ac -t fpe2 Change-Id: I6161203e52b7f7eaa1205de06e8241d7d40a7481 Signed-off-by: Evgeny Zinoviev <me(a)ch1p.io> --- A util/smctool/Makefile A util/smctool/description.md A util/smctool/smc.c A util/smctool/smc.h A util/smctool/smctool.c 5 files changed, 538 insertions(+), 0 deletions(-) git pull ssh://review.coreboot.org:29418/coreboot refs/changes/52/33052/1 diff --git a/util/smctool/Makefile b/util/smctool/Makefile new file mode 100644 index 0000000..ce7cca2 --- /dev/null +++ b/util/smctool/Makefile @@ -0,0 +1,38 @@ +## +## Makefile for smctool +## +## Copyright (C) 2019 Evgeny Zinoviev <me(a)ch1p.io> +## +## This program is free software; you can redistribute it and/or modify +## it under the terms of the GNU General Public License as published by +## the Free Software Foundation; version 2 of the License. +## +## This program is distributed in the hope that it will be useful, +## but WITHOUT ANY WARRANTY; without even the implied warranty of +## MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

As every DIMM only needs to terminate the line once at end of PCB, +the DC resistance is much lower as on DDR2 "tree" routing topology, which did +terminate on every IC. + +The disadvantage of "fly-by" is the more complex memory training that needs to +be done to find the DATA lane skew. + +After the skew has been measured, the DATA lanes needs to be delayed by the +memory controller, to make sure all signals are still synchronous to the CLK, +as seen be the memory controller (on READ) or the DRAM (on WRITE). + +![][flyby] + +[flyby]: ddr3_vs_ddr2.svg + +```eval_rst ++---------------------------+------------+----------------+ +| Feature | DDR2 | DDR3 | ++===========================+============+================+ +| Frequency | 200-533 | 400-800 | ++---------------------------+------------+----------------+ +| Routing | complex | easy | ++---------------------------+------------+----------------+ +| Termination DC resistance | very high | low | ++---------------------------+------------+----------------+ +| Memory training | easy | complex | ++---------------------------+------------+----------------+ +``` + diff --git a/Documentation/getting_started/ram_initialization/ddr3_vs_ddr2.dia b/Documentation/getting_started/ram_initialization/ddr3_vs_ddr2.dia new file mode 100644 index 0000000..e4b4d09 --- /dev/null +++ b/Documentation/getting_started/ram_initialization/ddr3_vs_ddr2.dia Binary files differ diff --git a/Documentation/getting_started/ram_initialization/ddr3_vs_ddr2.svg b/Documentation/getting_started/ram_initialization/ddr3_vs_ddr2.svg new file mode 100644 index 0000000..0b8db34 --- /dev/null +++ b/Documentation/getting_started/ram_initialization/ddr3_vs_ddr2.svg @@ -0,0 +1,298 @@ +<?xml version="1.0" encoding="UTF-8" standalone="no"?> +<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.0//EN" "http://www.w3.org/TR/2001/PR-SVG-20010719/DTD/svg10.dtd"> +<svg width="17cm" height="10cm" viewBox="507 221 325 192" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"> + <g> + <rect style="fill: #ffffff" x="508.366" y="221.748" width="323.85" height="190.069"/> + <rect style="fill: none;

Change in ...coreboot[master]: RFC: smbios: allow setting BIOS-version string from VPD variable
by Łukasz Siudut (Code Review) 10 Jun '23

Łukasz Siudut has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/32905 Change subject: RFC: smbios: allow setting BIOS-version string from VPD variable ...................................................................... RFC: smbios: allow setting BIOS-version string from VPD variable As in the title. Such approach allows for convenient setting of the firmware version and keep it in partition that is easily readable from both - coreboot binary and already running operating system. vpd_find is used directly as it returns pointer to vpd value which, by spec, is terminated by 0x00 (VPD_TYPE_TERMINATOR) anyway. This way we avoid copying string around and coming up with temporary buffer.
