Debdiff with proposed changes are attached to this bug. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1840847 Title: cpuinfo_linux_get_max_processors_count always warns Ubuntu default MAX cpu values (stderr) Status in cpuinfo package in Ubuntu: In Progress Status in linux package in Ubuntu: Confirmed Bug description: From bug: https://bugs.launchpad.net/bugs/1840511 clockhouse builds test started failing because of the presence of stderr whenever using the function: cpuinfo_linux_get_max_processors_count(void) From cpuid library. This happens because: ---- #if defined(__ANDROID__) && !defined(CPU_SETSIZE) /* * Android NDK headers before platform 21 do not define CPU_SETSIZE, * so we hard-code its value, as defined in platform 21 headers */ #if defined(__LP64__) static const uint32_t default_max_processors_count = 1024; #else static const uint32_t default_max_processors_count = 32; #endif #else static const uint32_t default_max_processors_count = CPU_SETSIZE; #endif ---- #if !defined(__ANDROID__) /* * sched.h is only used for CPU_SETSIZE constant. * Android NDK headers before platform 21 do have this constant in sched.h */ #include <sched.h> #endif ---- and resolving includes: x86_64-linux-gnu/bits/cpu-set.h: /* Size definition for CPU sets. */ #define __CPU_SETSIZE 1024 ---- And the warning: Warning in cpuinfo: kernel_max value of 8191 parsed from /sys/devices/system/cpu/kernel_max exceeds platform-default limit 1023 Will always be displayed in Ubuntu OS, when it should NOT (does not make any sense to trigger a warning for something that can't be changed). FOR THE KERNEL TEAM: Should ubuntu update sched.h and/or cpu-set.h to reflect its decision in using 8192 max CPUs ?
