Greetings, Recently I wrote about needing a patch to libsensors for it to work with new adm9240 driver. On testing with lm_sensors 2.9.1 I added read-only accessors to adm9240 fan_div, as this will break less user-space scripts and stuff. sensors vs my test direct sysfs access, with all alarms set: peetoo:0-002d$ sensors adm9240-i2c-0-2d Adapter: SMBus PIIX4 adapter at 7000 2.5V: +1.51 V (min = +1.37 V, max = +0.00 V) ALARM Vccp1: +2.01 V (min = +0.00 V, max = +0.00 V) ALARM 3.3V: +3.35 V (min = +3.13 V, max = +0.00 V) ALARM 5V: +5.18 V (min = +4.74 V, max = +0.00 V) ALARM 12V: +12.25 V (min = +11.38 V, max = +0.00 V) ALARM Vccp2: +2.59 V (min = +0.00 V, max = +0.00 V) ALARM fan1: 4116 RPM (min = 5973 RPM, div = 2) ALARM fan2: 0 RPM (min = 5973 RPM, div = 2) ALARM temp: +35.5?C (high = +0?C, hyst = +0?C) ALARM alarms: Chassis intrusion detection ALARM peetoo:0-002d$ ww_adm9240 in0_min in0_input in0_max alarm 0 1367 1510 0 ON 1 0 2025 0 ON 2 3128 3352 0 ON 3 4740 5182 0 ON 4 11375 12250 0 ON 5 0 2588 0 ON temp1_input temp1_max temp1_max_hyst alarm 1 35500 0 0 ON fan1_input fan1_min alarm 1 4091 5973 ON 2 0 5973 ON cpu0_vid: 2000 analog_out: 1235 alarms: 0x13df ci_alarm: ON normal operation: peetoo:0-002d$ sensors adm9240-i2c-0-2d Adapter: SMBus PIIX4 adapter at 7000 2.5V: +1.51 V (min = +1.37 V, max = +1.64 V) Vccp1: +2.02 V (min = +0.00 V, max = +3.59 V) 3.3V: +3.35 V (min = +3.13 V, max = +3.47 V) 5V: +5.18 V (min = +4.74 V, max = +5.26 V) 12V: +12.25 V (min = +11.38 V, max = +12.62 V) Vccp2: +2.57 V (min = +0.00 V, max = +3.59 V) fan1: 4116 RPM (min = 2987 RPM, div = 4) fan2: 1815 RPM (min = 1197 RPM, div = 8) temp: +35.5?C (high = +60?C, hyst = +55?C) alarms: peetoo:0-002d$ ww_adm9240 in0_min in0_input in0_max alarm 0 1367 1510 1641 -- 1 0 2011 3586 -- 2 3128 3352 3472 -- 3 4740 5182 5260 -- 4 11375 12250 12625 -- 5 0 2588 3586 -- temp1_input temp1_max temp1_max_hyst alarm 1 35500 60000 55000 -- fan1_input fan1_min alarm 1 4116 2987 -- 2 1815 1197 -- cpu0_vid: 2000 analog_out: 1235 alarms: 0x0000 ci_alarm: -- Please let me know if you want a patch for libsensors or if you feel leaving in a read accessor for fan_div is better.
