      Add missing va_end() to debug code.
      Found by cppcheck static analysis.
      Tagged as RTSupport-0_17-1 since our va_end is an empty macro.

      Clear the exclusive monitor when returning to pre-empted code · 70ed3564
      Jeffrey Lee authored
      Detail:
        s/scheduler - Add a second variant of the PreEmptionRecovery routine, which issues a CLREX on entry. Use a workspace variable to select which routine is required (for supporting multiple CPU architectures at runtime)
        h/scheduler - Declare new symbols exported by s/scheduler
        c/module - Initialise PreEmptionRecoveryPtr with the correct value, depending on whether the CPU supports LDREX/STREX or not

      Listen out for SeriousErrorV_Recover · 7e48c031
      Jeffrey Lee authored
      Detail:
        c/module, cmhg/RTSupportHdr, h/global, s/scheduler - Add a handler for SeriousErrorV, so we can be notified when the privileged mode stacks are being flattened. This is safer than watching out for serious errors to arrive via ErrorV, although the ErrorV approach is still necessary in order to deal with old kernels or serious error generators that don't currently use SeriousErrorV (e.g. FPASC/VFPSupport)

      Leave A bit set in SPSR when creating a thread · a7634fdf
      Robert Sprowson authored
      ARM have started using the extension bits (8 to 15) of the PSR, but have given bit 8 a safe default of being set (mask asynchronous aborts).
      Since the kernel doesn't handle these RTSupport will create the thread state with A=1 as it would be at reset.

      Cache translated error messages · 24de0af9
      Jeffrey Lee authored
      Detail:
        c/module - Make use of mess.c's error caching facility to avoid having to call MessageTrans when returning errors. Should give a bit of a performance boost when dealing with common errors (e.g. "Cannot yield in this context")

      Detail:
        Makefile - removed rendundant -cpu assembler flag that causes an error with asasm 2.00 due to two CPU types being specified

      Fix some nasty bugs. Add extensive debug logging code. · 83aa2484
      Jeffrey Lee authored
      Detail:
        s/scheduler - Fix PreEmptionRecovery and ThreadResumed to update LastKnownIRQsema with the new value of IRQsema
        s/scheduler - Fix SVC stack copying code to decrement both pointers instead of incrementing one and decrementing the other. Fix PreEmpt loading the wrong values for SVCStackCopy and SVCStackBase.
        s/scheduler - Fix Yielded loading Context into R2, and thus overwriting any timeout the routine specified
        c/module, hdr/RTSupport, Resources/UK/Messages - Module now errors when RTSupport SWIs are called with nonzero flags
        Makefile, c/module, h/scheduler, s/scheduler - Added lots of debugging code, based around debuglib for C code and DADebug for assembler code. Debug code toggled on/off by passing DEBUG=TRUE to makefile. PC-relative variables shifted to middle of file to keep them within LDR range when debugging enabled.

      Update to work with zero page relocation · 449310ba
      Jeffrey Lee authored
      Detail:
        c/cmodule - Try using OS_ReadSysInfo 6 to find IRQsema before falling back on the legacy address
        h/scheduler - Add IRQsema pointer extern, update ThreadResumed extern to cope with it now being in a data area
        s/scheduler - Use workspace IRQsema pointer instead of hardcoded legacy address. Moved PreEmptionRecovery & ThreadResumed into data area for easier access to IRQsema ptr.

      Fixes & improvements for RTSupport module · 907e3d01
      Jeffrey Lee authored
      Detail:
        - Makefile (hopefully temporarily) modified to use "-cpu 3" setting for compiling C files, to work around internal compiler error
        - RT_Deregister fixed (in s/scheduler) to behave properly if a routine attempts to deregister itself after being entered from the foreground via RT_Yield
        - Simple test program added to test correct behaviour of RT_Deregister
        - SVC stack allocation routines rewritten to cope with the possibility that OS_DynamicArea 9/10 may be unable to move pages (e.g. RT_Deregister called while IRQSema is nonzero)
        - Stack allocation routine also attempts to deal with kernels which have broken sparse area error reporting (anything below version 5.15), by falling back on a simpler allocation scheme that doesn't resize the dynamic area.
        - Erroneous comment in s/scheduler fixed
        - Erroneous #define in h/scheduler fixed

      Fixes some nasty bugs. · b44fb24b
      Ben Avison authored
      Detail:
        * First bug was that due to a careless slip-up in the very last stage of
          the process of switching to a routine (the loading of the SPSR), all
          routines were actually being entered in SYS mode with IRQs disabled. This
          was leading to horrendous interrupt latency - exactly the situation this
          module was written to avert! The most obvious reproducible symptom was
          that the real time clock ran slowly.
        * Once this was fixed, it revealed the presence of a more complicated bug:
          the module wasn't including the most-recently-executed routine along
          with the list of other routines in a non-sleeping state for a certain
          sub-set of actions. This was fixed by setting the pollword pointer to
          yet another magic address while it was executing, to minimise the
          disruption to existing code.
      Admin:
        Tested with a deinterlacing routine.
