Hello, We recently reverse engineered PWM-based voltage management but found an odity in the input clock frequency for the PWM controller. It seems like RM is assuming an input clock of 27.648 MHz instead of the actual 27MHz crystal found on the board. I thus have the following questions: - Is it a fixed value hardcoded in RM? (Curre...

I am using ST micro's STM32F103 chip with their AN2812 development code. It uses a PWM output, resulting in low-quality sound. Can I just use a scaled version of the PWM to drive a DAC? (i.e. is the output linear, or is there shaping to make the PWM output work?) Any feedback, links or pointers would be greatly appreciated.

I saw a Help e-mail related to MLE. Does R have a probability weighted method (PWM) estimator function? I can't seem to find anything on PWM, unless my eyes are playing trick on me. [[alternative HTML version deleted]]

Yeah, this would hinder our reclocking efforts :s The best idea I can come up with is to fake the temperature (register 0x20408) to 1°C (minimum the hardware allows us) and read the PWM duty, then we can get the maximum duty by setting the temperature to the fan_boost threshold. Not sure we have a sure-way of computing the fan_boost threshold though, maybe we can just use of the thermal throttling threshold for this (more on this later in the email). In any case, all of these so...

Hi, I have just setup CentOS4 on a system and want to get "fancontrol" working.. I am able to get lm_sensors configured but when I run pwmconfig I am told there are no modules loaded.. What module needs to be loaded for pwmconfig and fancontrol to work? (Board does support PWM in the fans because fancontrol worked on this pc with Ubuntu) TIA

Hello guys, For a patch to this nouveau bug [1] I'm trying to implement the sysfs interface for two properties (linear_min and linear_max) nouveau uses internally to decide when to raise the fan speed. The initial idea was to have them as custom sysfs attributes, but I was advised to try to fit them into the hwmon sysfs interface. And this is when I hit a little roadblock. If my

What GPUs have you observed this on? > Thanks Andy, As far as I can tell, it is the case for all GPUs using the PWM-based voltage management. To be more specific, we have seen this behaviour on a GK106 (mobile), a GM117 and a GM204.

A NV34 GPU was seeing temp and pwm entries in hwmon, which would error out when read. These should not have been visible, but also the whole hwmon object should just not have been registered in the first place.
