Oops! Forgot to mention that I'm using lm_sensors-2.8.7 for the userspace programs. (Standard with RHEL4). ---------- Forwarded Message ---------- Subject: lm87 on kernel 2.6.9: kinda-sorta working. What else is needed? Date: Tuesday 21 March 2006 12:49 pm From: Steve Snyder <swsnyder at insightbb.com> To: lm-sensors at lm-sensors.org I am attempting to get LM87 support on a RHEL4 kernel. This kernel, 2.6.9-34.EL, does not include the lm87 driver, so I'm trying to add it myself. My desire is to get health information from my Supermicro P3TDLE M/B (http://www.supermicro.com/products/motherboard/P3/LE/P3TDLE.cfm). I got the lm87.c from the standard 2.6.10 kernel and simply dropped it into Red Hat's source tree. After adding the required normal_i2c_range[] and normal_isa_range{} references (see below) it built without complaint. No errors or warnings are seen in the system log at load time, either. At runtime, though, I get this: # sensors lm87-i2c-0-2e Adapter: SMBus PIIX4 adapter at 0580 ERROR: Can't get IN1 data! ERROR: Can't get IN3 data! ERROR: Can't get IN4 data! fan1: 5153 RPM (min = 2848 RPM, div = 2) fan2: 5153 RPM (min = 2848 RPM, div = 2) temp1: +33?C (low = +0?C, high = +50?C) ERROR: Can't get TEMP2 data! Yes, this is a dual-CPU board, and the single temperature shown is reasonably close to the values reported by the BIOS in the BIOS setup menu. This are the 2 lines I added to the 2.6.10 version of lm87.c to pacify the build complaints: static unsigned short normal_i2c_range[] = { I2C_CLIENT_END }; static unsigned int normal_isa_range[] = { I2C_CLIENT_ISA_END }; So now the full set of address declarations look like this: static unsigned short normal_i2c[] = { 0x2c, 0x2d, 0x2e, I2C_CLIENT_END }; static unsigned short normal_i2c_range[] = { I2C_CLIENT_END }; static unsigned int normal_isa[] = { I2C_CLIENT_ISA_END }; static unsigned int normal_isa_range[] = { I2C_CLIENT_ISA_END }; Any advice out there on what else is needed to get LM87 support with this 2.6.9 (+ backported tweaks and fixes) kernel? Thanks. -------------------------------------------------------
