chao an	4c8d244fae	sched/getpid: replace syscall getpid/tid/ppid() to kernel version NuttX kernel should not use the syscall functions, especially after enabling CONFIG_SCHED_INSTRUMENTATION_SYSCALL, all system functions will be traced to backend, which will impact system performance.

qinwei1	8021dfece6	sched/task/task_getpid: getpid should return process id not thread id Summary: implement the right semantics: 1. getpid should return the main thread id 2. gettid should return the current thread id Refer to: https://github.com/apache/incubator-nuttx/issues/2499 https://github.com/apache/incubator-nuttx/pull/2518 Signed-off-by: qinwei1 <qinwei1@xiaomi.com>	2022-11-17 17:58:08 +08:00
Xiang Xiao	3d0320f891	libc/sched: Map the nice value more correctly from https://pubs.opengroup.org/onlinepubs/007904875/functions/setpriority.html: 1.The nice value shall in the range [-{NZERO},{NZERO} -1] 2.Lower nice value shall cause more favorable scheduling Signed-off-by: Xiang Xiao <xiaoxiang@xiaomi.com> Change-Id: I5ad60d92abc3b69fbaa406da68cec2e40ca3fa6d	2021-06-24 08:50:48 -03:00
