Subject: [PATCH v2 10/13] tools/nolibc: sys_poll: add pure 64bit poll
Date: Tue, 30 May 2023 03:58:42 +0800 [thread overview]
Message-ID: <f0956ce681eb8abc81c91e6b34174034d5b32c07.1685387484.git.falcon@tinylab.org> (raw)
In-Reply-To: <cover.1685387484.git.falcon@tinylab.org>
It's time to provide 64bit time structs for all platforms, for y2038 is
near.
ppoll_time64 has been added from v4.20 and the last arch support is at
least from v5.0.0
