Best Regards _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxxx https://lists.xenproject.org/mailman/listinfo/xen-usersThis change of behavior was introduced with https://xenbits.xen.org/gitweb/?p=xen.git;a=commitdiff;h=72e038450d3d5de1a39f0cfa2d2b0f9b3d43c6c6 It was intended to hide Thermal info from PV guests but seems it got hidden from Dom0 as well. I was having same problem and there are 2 ways through which it could be solved. Modify Xen to not hide EAX or modify linux Dom0 kernel. To modify dom0 kernel, you'd have to edit https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/arch/x86/kernel/cpu/common.c?h=v5.3.7#n913 - c->x86_capability[CPUID_6_EAX] = cpuid_eax(0x00000006); + c->x86_capability[CPUID_6_EAX] = native_cpuid_eax(0x00000006); _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxxx https://lists.xenproject.org/mailman/listinfo/xen-usersThanks for your information, i tried to change common.c inside of the kernel 5.3.7 sources but now dmesg prints this while booting the system with xen 4.13.0-rc2: [ 13.090126] coretemp coretemp.0: Using relative temperature scale!

I will try this way now Best Regards _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxxx https://lists.xenproject.org/mailman/listinfo/xen-usersSure, modifying from Xen should create more stable effect. Before that, can you share # cpuid -r -1 ? We need to look for 0x00000006 0x00: eax=0x00000077 _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxxx https://lists.xenproject.org/mailman/listinfo/xen-users i am currently under Kernel 4.19.0-6-amd64 (Debian10) cpuid prints out this; cpuid -r -1 CPU: 0x00000000 0x00: eax=0x0000000a ebx=0x756e6547 ecx=0x6c65746e edx=0x49656e69 0x00000001 0x00: eax=0x000006fb ebx=0x03040800 ecx=0x0000e3bd edx=0xbfebfbff 0x00000002 0x00: eax=0x05b0b101 ebx=0x005657f0 ecx=0x00000000 edx=0x2cb43049 0x00000003 0x00: eax=0x00000000 ebx=0x00000000 ecx=0x00000000 edx=0x00000000 0x00000004 0x00: eax=0x0c000121 ebx=0x01c0003f ecx=0x0000003f edx=0x00000001 0x00000004 0x01: eax=0x0c000122 ebx=0x01c0003f ecx=0x0000003f edx=0x00000001 0x00000004 0x02: eax=0x0c004143 ebx=0x03c0003f ecx=0x00000fff edx=0x00000001 0x00000005 0x00: eax=0x00000040 ebx=0x00000040 ecx=0x00000003 edx=0x00000020 0x00000006 0x00: eax=0x00000001 ebx=0x00000002 ecx=0x00000001 edx=0x00000000 0x00000007 0x00: eax=0x00000000 ebx=0x00000000 ecx=0x00000000 edx=0x00000000 0x00000008 0x00: eax=0x00000400 ebx=0x00000000 ecx=0x00000000 edx=0x00000000 0x00000009 0x00: eax=0x00000000 ebx=0x00000000 ecx=0x00000000 edx=0x00000000 0x0000000a 0x00: eax=0x07280202 ebx=0x00000000 ecx=0x00000000 edx=0x00000503 0x80000000 0x00: eax=0x80000008 ebx=0x00000000 ecx=0x00000000 edx=0x00000000 0x80000001 0x00: eax=0x00000000 ebx=0x00000000 ecx=0x00000001 edx=0x20100800 0x80000002 0x00: eax=0x65746e49 ebx=0x2952286c ecx=0x726f4320 edx=0x4d542865 0x80000003 0x00: eax=0x51203229 ebx=0x20646175 ecx=0x20555043 edx=0x51202020 0x80000004 0x00: eax=0x30303636 ebx=0x20402020 ecx=0x30342e32 edx=0x007a4847 0x80000005 0x00: eax=0x00000000 ebx=0x00000000 ecx=0x00000000 edx=0x00000000 0x80000006 0x00: eax=0x00000000 ebx=0x00000000 ecx=0x10008040 edx=0x00000000 0x80000007 0x00: eax=0x00000000 ebx=0x00000000 ecx=0x00000000 edx=0x00000000 0x80000008 0x00: eax=0x00003024 ebx=0x00000000 ecx=0x00000000 edx=0x00000000 0x80860000 0x00: eax=0x07280202 ebx=0x00000000 ecx=0x00000000 edx=0x00000503 0xc0000000 0x00: eax=0x07280202 ebx=0x00000000 ecx=0x00000000 edx=0x00000503 hope its enough, if not please tell and i will give cpuid from Kernel 5.3.7 or Kernel 5.3.11 .. at the moment i am switching trough both Kernel Version to get the Temperatures Output on Dom0 working again .... Would be nice if its possible from some of the Dev's to make an switch or something to hide or to show temperatures back again.
