From 9ca8dbcc65cfc63d6f5ef3312a33184e1d726e00 Mon Sep 17 00:00:00 2001 From: Yunhong Jiang Date: Tue, 4 Aug 2015 12:17:53 -0700 Subject: Add the rt linux 4.1.3-rt3 as base Import the rt linux 4.1.3-rt3 as OPNFV kvm base. It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and the base is: commit 0917f823c59692d751951bf5ea699a2d1e2f26a2 Author: Sebastian Andrzej Siewior Date: Sat Jul 25 12:13:34 2015 +0200 Prepare v4.1.3-rt3 Signed-off-by: Sebastian Andrzej Siewior We lose all the git history this way and it's not good. We should apply another opnfv project repo in future.

There are many different revisions of the + firmware and thus effectivly many different revisions of the uGuru. + Below is an incomplete list with which revisions are used for which + Motherboards: + uGuru 1.00 ~ 1.24 (AI7, KV8-MAX3, AN7) + uGuru 2.0.0.0 ~ 2.0.4.2 (KV8-PRO) + uGuru 2.1.0.0 ~ 2.1.2.8 (AS8, AV8, AA8, AG8, AA8XE, AX8) + uGuru 2.3.0.0 ~ 2.3.0.9 (AN8) + uGuru 3.0.0.0 ~ 3.0.x.x (AW8, AL8, AT8, NI8 SLI, AT8 32X, AN8 32X, + AW9D-MAX) + The abituguru3 driver is only for revison 3.0.x.x motherboards, + this driver will not work on older motherboards. For older + motherboards use the abituguru (without the 3 !) driver. + +Authors: + Hans de Goede , + (Initial reverse engineering done by Louis Kruger) + + +Module Parameters +----------------- + +* force: bool Force detection. Note this parameter only causes the + detection to be skipped, and thus the insmod to + succeed. If the uGuru can't be read the actual hwmon + driver will not load and thus no hwmon device will get + registered. +* verbose: bool Should the driver be verbose? + 0/off/false normal output + 1/on/true + verbose error reporting (default) + Default: 1 (the driver is still in the testing phase) + +Description +----------- + +This driver supports the hardware monitoring features of the third revision of +the Abit uGuru chip, found on recent Abit uGuru featuring motherboards. + +The 3rd revision of the uGuru chip in reality is a Winbond W83L951G. +Unfortunately this doesn't help since the W83L951G is a generic microcontroller +with a custom Abit application running on it. + +Despite Abit not releasing any information regarding the uGuru revision 3, +Louis Kruger has managed to reverse engineer the sensor part of the uGuru. +Without his work this driver would not have been possible. + +Known Issues +------------ + +The voltage and frequency control parts of the Abit uGuru are not supported, +neither is writing any of the sensor settings and writing / reading the +fanspeed control registers (FanEQ) + +If you encounter any problems please mail me and +include the output of: "dmesg | grep abituguru" -- cgit 1.2.3-korg
