Donenfeld <Jason@zx2c4.com> +Date: Fri, 04 May 2018 03:48:23 +0200 +Subject: [PATCH] runtime: use CLOCK_BOOTTIME in nanotime on Linux + +This makes timers account for having expired while a computer was +asleep, which is quite common on mobile devices. Note that BOOTTIME is +identical to MONOTONIC, except that it takes into account time spent +in suspend. In Linux 4.17, the kernel will actually make MONOTONIC act +like BOOTTIME anyway, so this switch will additionally unify the +timer behavior across kernels. + +BOOTTIME was introduced into Linux 2.6.39-rc1 with 70a08cca1227d in +2011. + +Fixes #24595 + +Change-Id: I7b2a6ca0c5bc5fce57ec0eeafe7b68270b429321 +--- + +diff --git a/src/runtime/sys_linux_386.s b/src/runtime/sys_linux_386.s +index 8d5a4ff..bfad064 100644 +--- a/src/runtime/sys_linux_386.s ++++ b/src/runtime/sys_linux_386.s +@@ -285,13 +285,13 @@ LEAL 8(SP), BX // &ts (struct timespec) MOVL BX, 4(SP) @@ -17,11 +38,12 @@ diff -ru b/src/runtime/sys_linux_386.s a/src/runtime/sys_linux_386.s LEAL 8(SP), CX INVOKE_SYSCALL -diff -ru b/src/runtime/sys_linux_amd64.s a/src/runtime/sys_linux_amd64.s ---- b/src/runtime/sys_linux_amd64.s 2018-04-30 22:26:39.000000000 +0200 -+++ a/src/runtime/sys_linux_amd64.s 2018-05-09 17:09:42.319531743 +0200 -@@ -258,7 +258,7 @@ -
