15cbddf4	2020-12-13T18:00:20	linux/SDL_threadprio.c: fix build on older systems: SCHED_RESET_ON_FORK is in kernel >= 2.6.32.
07eae7d6	2020-11-11T08:47:18	Fix process randomly getting killed when SDL_THREAD_PRIORITY_HIGH/TIME_CRITICAL is set When we request realtime priority from rtkit, we have a rttime limit. If we exceed that limit, the kernel will send SIGKILL to the process to terminate it. This isn't something that most high priority processes will want, only processes that selectively opt into SCHED_RR/FIFO through SDL_HINT_THREAD_PRIORITY_POLICY should be subject to this level of scrutiny. This change: * Switches non-apple posix OSs to use SCHED_OTHER instead of SCHED_RR for SDL_THREAD_PRIORITY_HIGH/SDL_THREAD_PRIORITY_TIME_CRITICAL. * Fixes using a hardcoded RLIMIT_RTTIME, instead queries it from rtkit * Only sets RLIMIT_RTTIME for MakeRealtime rtkit requests * Adds a note regarding the possible SIGKILL with SDL_HINT_THREAD_PRIORITY_POLICY * Introduces SDL_HINT_THREAD_FORCE_REALTIME_TIME_CRITICAL to allow apps to acquire realtime scheduling policies on Linux
94924f01	2020-11-09T10:11:55	Fix failing to set high priority for threads on Linux desktop. Debugging inside rtkit showed we were failing the RLIMIT_RTTIME check, now that we're asking for realtime and not just high-priority due to a change in SDL. Between that and the DBus code in SDL being wrong in previous changelist I'm not sure how this could have ever worked.

abd58418	2020-05-26T13:19:19	Make some changes to SDL_SetThreadPriority to try and have SDL transparently handle more of the work. 1. Comment that SDL_SetThreadPriority will make any necessary system changes when applying priority. 2. Add a hint to override SDL's default behavior for scheduler policy. 3. Modify the pthreads SDL_SetThreadPriority so that instead of just using the current thread scheduler policy it will change it to a policy that should work best for the requested priority. 4. Add hint checks in SDL_SetThreadPriority so that #3 can be overridden if desired. 5. Modify the Linux SDL_SetThreadPriority so that in the case that policy, either by SDL defaults or from the hint, is a realtime policy it uses the realtime rtkit API. 6. Prior to calling rtkit on Linux make the necessary thread state changes that rtkit requires. Currently this is done every time as it isn't expected that SDL_SetThreadPriority will be called repeatedly for a thread.
ba95fa61	2020-04-08T08:42:09	Revert "Fix incorrectly terminated MakeThreadHighPriority dbus message" The first terminator is for input parameters. The second terminator was for the output parameters. If an error occurs when calling MakeThreadHighPriority(), e.g. a bad thread id, then the reply from connection_send_with_reply_and_block() will be null.

But there is some scheduler config that rtkit needs the app to setup.
