This bug appears to have been reported against 'rawhide' during the Fedora 22 development cycle. Changing version to '22'. More information and reason for this action is here: https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora22 This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle. Changing version to '24'. More information and reason for this action is here: https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora24#Rawhide_Rebase Actually this reports zero on ARMv7/aarch64/ppc64/ppc64le although it reports correctly on s390x David can you confirm if this is still the case for F-25+ (In reply to Peter Robinson from comment #3) > Actually this reports zero on ARMv7/aarch64/ppc64/ppc64le although it > reports correctly on s390x In upstream only x86_64, s390, and pp64/ppc64le have support for detection of hardware cache line sizes. ARM has not implemented this yet, so all of these routines return 0 for cache line sizes (meaning the size is not known). A return of -1 would indicate no limit, and that's not correct to return. |
