Public bug reported: Description: Cometlake -U 6+2 is using a different CPU Model number: DEC 166, HEX: A6
We need the intel_rapl patch to support CML-U6+2 We read the msr, which show the values: root@p-cml02~ # ./rdmsr 0x639 7ed34e root@p-cml02~ # ./rdmsr 0x611 5ce685 Domain Model-Specific Register Powercap Name Turbostat Column Package 0x611 package PkgWatt Power Plane 0 (PP0), Processor Cores 0x639 core CorWatt While in linux OS, there is no rapl driver loaded, no any sysfs files for RAPL. root@p-cml02~ # cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 166 model name : Intel(R) Core(TM) i7-10710U CPU @ 1.10GHz stepping : 0 microcode : 0xb0 cpu MHz : 2301.349 cache size : 12288 KB physical id : 0 siblings : 12 core id : 0 cpu cores : 6 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 22 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb rdtscp lm constant_tsc art arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc cpuid aperfmperf pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 sdbg fma cx16 xtpr pdcm pcid sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm abm 3dnowprefetch cpuid_fault epb invpcid_single ssbd ibrs ibpb stibp ibrs_enhanced tpr_shadow vnmi flexpriority ept vpid ept_ad fsgsbase tsc_adjust bmi1 avx2 smep bmi2 erms invpcid mpx rdseed adx smap clflushopt intel_pt xsaveopt xsavec xgetbv1 xsaves dtherm ida arat pln pts hwp hwp_notify hwp_act_window hwp_epp md_clear flush_l1d arch_capabilities bugs : spectre_v1 spectre_v2 spec_store_bypass bogomips : 3200.00 clflush size : 64 cache_alignment : 64 address sizes : 39 bits physical, 48 bits virtual Target Kernel: 5.5 Target Release: 20.10 ** Affects: intel Importance: Undecided Status: Fix Committed ** Affects: ubuntu Importance: Undecided Status: New ** Tags: intel-kernel-20.10 ** Also affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1880496 Title: [CML-U62] Need enable intel_rapl patch support for Comet lake- U 6+2 To manage notifications about this bug go to: https://bugs.launchpad.net/intel/+bug/1880496/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
