Re: Disk swapping issues

This seems to have resolved the issue of swapping discs, however it now instantly locks the machine when a disc swap happens. I'm currently investigating why and hope it's resolvable I've managed to track down the issue and find a solution. RTSupport is again the root cause of the issue, it looks l...

Re: Codelet recycling

Three SWI's remain which can't currently be recycled:
  • SharedCLibraryAPCS_R
  • Sound_Configure
  • Vector Claims (OS_AddCallBack, OS_Claim, OS_CallAfter, OS_CallEvery, OS_AddToVector, OS_ClaimDeviceVector)
These need moving to static entry points so the original SWI instruction can be released

26bit Module support

Notes on providing 26bit module support Create a stub module header in the JIT RMA Heap and insert into the RMA, this needs to contain the SWI table, Command table and all Module entry points: Init, Start, Exit, Service (coded) All entry points need a managed entry/exit (coded) JIT RMA Heap and code...

WIMP support

Notes on providing WIMP support
  1. At all ADFFS entry points, check Wimp_ReadSysInfo 5 or OS_ReadSysInfo 6 DomainId to confirm the current task is one we're handling
  2. Spawn a new JIT area for child tasks (created via either Filer_Run or Wimp_StartTask)

Re: Codelet reentrancy

Ironically the codelet reentrancy is now causing the Pi to crash. It looks like the IRQ stack is being reset as RISCOS' IRQ handler exits, I need to investigate further. This turned out to be an issue design decision made in the RTSupport module where it resets the IRQ stack when it exits. It would...

Disk swapping issues

There are several reasons why it's difficult to swap discs in some games. The root cause itself is when a game sits in a tight loop waiting for input, be it a key or a disc change. Blowpipe, Chuck Rock and Xenon 2 all sit in loops of less than a dozen instructions; Blowpipe and Xenon 2 continually t...
