From 307f84513342d87e0dba268e4040a85b31e6227f Mon Sep 17 00:00:00 2001 From: Denis Ivanov <[email protected]> Date: Fri, 6 Jul 2018 12:03:15 +0300 Subject: [PATCH 1/2] RISC-V: Fixed return code in _times syscall. Upon successful completion, times() shall return the elapsed real time, in clock ticks, since an arbitrary point in the past (for example, system start-up time).
