Is the driver loaded on both GPUs? Check your dmesg output. Probably best to file a bug.

These are some messages related to drm/i2c from dmesg output:

As you can see there is only temperature of gpu1. Temperature of gpu0 should be 85-90?C (Yes I know it's too high due to my old system case :/ ). Sometimes it rises above 90?C and I have to manually turn power_profile to "high" (which was set to "auto") to speed up gpu fan to cool down a bit. That's why I need gpu0's temperature rather than gpu1's. Is there anyway to get gpu0's temperature with open source radeon driver?

Is the driver loaded on both GPUs? Check your dmesg output. Probably best to file a bug.

Hello. My video card is 4870x2 and I'm using open source radeon driver (xf86-video-ati). I can only get temperature of gpu1 but not gpu0.

These are what I set in kernel:

Code:

Device Drivers --->
    Graphics support --->
        <*> Support for frame buffer devices --->
            <*> ATI Radeon display support [*] DDC/I2C for ATI Radeon support

These are detected by lm_sensors regarding Radeon i2c:

My system:

Code:

$ uname -a
Linux localhost 3.4.2-gentoo #2 SMP Wed Jun 13 20:05:53 CST 2012 x86_64 Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz GenuineIntel GNU/Linux

As you can see there is only temperature of gpu1. Temperature of gpu0 should be 85-90?C (Yes I know it's too high due to my old system case :/ ). Sometimes it rises above 90?C and I have to manually turn power_profile to "high" (which was set to "auto") to speed up gpu fan to cool down a bit. That's why I need gpu0's temperature rather than gpu1's. Is there anyway to get gpu0's temperature with open source radeon driver?

modprobe lm63

I've tried that, again, to no avail.

I noticed something on dmesg:

Code:

$ dmesg | egrep i2c [ 1.347993] i2c-core: driver [adp5520] using legacy suspend method [ 1.347996] i2c-core: driver [adp5520] using legacy resume method [ 9.066050] i2c /dev entries driver

i2c-core shows up on the boot process, but it is not showing on lsmod:

Code:

lsmod | egrep i2c* i2c_dev 13399 0 i2c_algo_bit 13436 1 radeon i2c_viapro 13153 0

Thanks for helping.

I'll ask on the mailing lists.

Your best bet is to ask on one of the lm_sensors/hwmon mailing lists. I'm not sure why the module isn't loading.

As you see i2c_core is missing.

Code:

$modprobe -v i2c_core
$

Code:

$ lsmod | egrep i2c*

i2c_algo_bit           13436  1 radeon

I tried to modprobe it but no avail. It does not give any errors.

Code:

$ dmesg | egrep lm63
$

Nothing on dmesg either.

Also, I'm running a drm-next Kernel from Ubuntu's Mainline Kernel PPA.

Is there anything else that can be done?
