Summary: sensors are inaccessible on radeon X1950 PCIe Product: DRI Version: XOrg CVS Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: thierry.vignaud@gmail.com

My X1950 (RV350) Radeon card has a hw monitoring chip onboard. I read that it's now possible to access it via the dri framework and the standard lm-sensors toolkit, and the lm63 is the driver I need.

I ran sensors-detect:

Next adapter: Radeon i2c bit bus 0x92 (i2c-2) Do you want to scan it? (YES/no/selectively): Client found at address 0x4c (...) Probing for `National Semiconductor LM63'... Success! (confidence 6, driver `lm63') (...) Now follows a summary of the probes I have just done. (...) Driver `lm63': * Bus `Radeon i2c bit bus 0x92' Busdriver `UNKNOWN', I2C address 0x4c Chip `National Semiconductor LM63' (confidence: 6)

But lm63 doesn't seem to work. Modules load without any error, but if I run 'sensors', only the motherboard sensors are printed. qFrom dmesg: i2c /dev entries driver smsc47b397: found SMSC LPC47B397-NC (base address 0x0900, revision 1)

With kernel 2.6.3x and 3.0 With xserver 1.7, 1.9 & 1.10 with x11 driver 6.14.1 & previous too
