On some of these SoCs it's not possible to # recalibrate the TSC because there is no reference (PIT, HPET) # available. # # With some reverse engineering it was established that the possible # frequencies are derived from the base clock with fixed multiplier / # divider pairs. # # For the CPU models which have a known crystal frequency the kernel now # uses multiplier / divider pairs which bring the frequencies closer to # reality and fix the observed time drift issues" # # * tag 'x86-timers-2020-03-30' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # x86/tsc_msr: Make MSR derived TSC frequency more accurate # x86/tsc_msr: Fix MSR_FSB_FREQ mask for Cherry Trail devices # x86/tsc_msr: Use named struct initializers # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 458ef2a25e0cbdc216012aa2b9cf549d64133b08 # < make -s -j 32 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allnoconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- allnoconfig WARNING: unmet direct dependencies detected for COMPAT_BINFMT_ELF Depends on [n]: COMPAT [=y] && BINFMT_ELF [=n] Selected by [y]: - COMPAT [=y] && SPARC64 [=y] # < make -s -j 32 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allnoconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- help # make -s -j 32 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allnoconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- olddefconfig WARNING: unmet direct dependencies detected for COMPAT_BINFMT_ELF Depends on [n]: COMPAT [=y] && BINFMT_ELF [=n] Selected by [y]: - COMPAT [=y] && SPARC64 [=y] WARNING: unmet direct dependencies detected for COMPAT_BINFMT_ELF Depends on [n]: COMPAT [=y] && BINFMT_ELF [=n] Selected by [y]: - COMPAT [=y] && SPARC64 [=y] # make -s -j 32 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allnoconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- :1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] kernel: arch/sparc/boot/image is ready kernel: arch/sparc/boot/zImage is ready Completed OK # rm -rf /kisskb/build/linus_sparc64-allnoconfig_sparc64 # Build took: 0:00:17.746210
