Dear list, I am running CURRENT on an HP elitebook 745 G3 which comes with a AMD A12-8800B CPU. All in all, it runs very well with just a few nits to pick. Two of them are ACPI related.
1) there are 5 thermal zones defined out of which only two provide reasonable numbers it seems: hw.acpi.thermal.tz4.temperature: 34.1C hw.acpi.thermal.tz3.temperature: 0.1C hw.acpi.thermal.tz2.temperature: 0.1C hw.acpi.thermal.tz1.temperature: 0.1C hw.acpi.thermal.tz0.temperature: 56.1C my gut feeling is that tz0-tz3 may be the CPU cores and tz4 would be the GPU (which does not work in BSD ATM, hence consistently lower temp). I guess this is not a big deal (everything works) but I still wonder how to fix it. 2) turbo mode: this is a more major issue. sysctl reports the following for all four cores: dev.cpu.0.cx_lowest: C2 dev.cpu.0.cx_supported: C1/1/0 C2/2/400 dev.cpu.0.freq_levels: 2100/4717 1800/3450 1400/2320 dev.cpu.0.freq: 2100 >From the intel CPUs w/ turbo mode I had before I know that there should be (at least) a 2101 frequency indicating the turbo clock. This frequency is absent, I suspect this means turbo mode does not work. How can I debug this? I believe also that this AMD chip has multiple frequencies above the base clock of 2100, so how would that show?
