++What is it?
++The Wine-RT patch allows programs that use windows' concept of thread priority to gain similar functionality under linux.  It maps windows priority levels to linux scheduling policies.  THREAD_PRIORITY_ABOVE_NORMAL, THREAD_PRIORITY_HIGHEST and THREAD_PRIORITY_TIME_CRITICAL levels which are made to run as linux SCHED_FIFO threads at priority levels that are defined by the WINERT variable.  THREAD_PRIORITY_NORMAL threads are run as normal linux threads (as all threads are without the patch), and the priorities below normal (THREAD_PRIORITY_BELOW_NORMAL, THREAD_PRIORITY_LOWEST) are run as SCHED_BATCH.  THREAD_PRIORITY_IDLE threads are run as SCHED_IDLE.
++Windows' concept of priority classes is not implemented at all.
++
++Please note that threads running SCHED_FIFO might hang your entire system, so please exercise caution! 
++
++How does it work?
++When a windows program asks for a thread to be run at a higher priority, Wine will ask the linux system to schedule it as a SCHED_FIFO thread, which means that the tread will keep on executing until it has either finished, voluntarily yields execution or gets preempted by a higher priority SCHED_FIFO thread.  This is already done by many linux audio applications, to ensure less xruns on lower buffer sizes.  With Wine-RT, the same thing can be done for Wine applications.
++ 
++How to use it?
++The Wine-RT functionality is not enabled by default. Instead it is controlled by 2 environment variables "WINE_RT" and "WINE_SRV_RT".
++
++The "WINE_RT" variable has 2 purposes, it has to be set in order to activate the patch, and it determines the priority of the SCHED_FIFO threads, Its value can be set from 1 to your system's rtprio max value minus 10, as set in limits.conf or limits.d/audio.conf. (In Debian, Ubuntu and KXStudio this value is 99). THREAD_PRIORITY_ABOVE_NORMAL threads will run at this  priority level, THREAD_PRIORITY_HIGHEST threads at this level + 5, and THREAD_PRIORITY_TIME_CRITICAL threads at this level + 10.
++
++WINE_SRV_RT makes the wineserver main thread run SCHED_FIFO.  Valid values range from 1 to your system's rtprio max value.
++
++We can set these variables in 2 simple ways.
++First one is using a terminal with "exports", like this:
++export WINE_RT=#
++export WINE_SRV_RT=#
++wine <app>
++
++or just prefix your application with 'env VARIABLE=value', like this:
++env WINE_RT=# WINE_SRV_RT=# wine <app>
++
++A recommended starting point might be "env WINE_RT=15 WINE_SRV_RT=10 wine appname.exe".
