Subject: [PATCH v5 0/2] allow creating thread with real-time priority
Date: Thu, 26 Oct 2023 16:19:35 +0200	[thread overview]
Message-ID: <20231026142749.1174372-1-thomas@monjalon.net> (raw)
In-Reply-To: <20231024125416.798897-1-thomas@monjalon.net>

Real-time thread priority was been forbidden on Unix
because of problems they can cause.
Warnings and helpers are added to avoid deadlocks,
so real-time can be allowed on all systems.

Thomas Monjalon (2):
  eal: add thread yield functions
  eal/unix: allow creating thread with real-time priority

v1: no yield at all
v2: more comments, sched_yield() and Sleep(0) on Windows
v3: 2 yield functions with sleep in realtime version
v4: runtime warning, longer sleep on Unix and lighter yield on Windows
v5: fix build and increase Unix sleep to 1 ms

Thomas Monjalon (2):
  eal: add thread yield functions
  eal/unix: allow creating thread with real-time priority
