- ______________________________________________________________________________
-
- If you want to run PoolMem in conjunction with the ppc.library, you must
-
- a) launch the ppc.library in front of PoolMem, and
- b) specify the "NOMERGE" option.

- ******************************************************************************
- Some system handlers have been shown to be too low on stack, this might
- cause problems!
-
- The new PatchRAM in this archive will fix this for the RAM disk, and YOU
- SHOULD fix this for the FFS and the boot partitions. The minimum recommended
- stack size is 1024 bytes, DO NOT GO BELOW. IT MIGHT WORK, but this is asking
- for trouble.

- Version History
-
- This is not the complete version history, check the PoolMem.guide for details.
-
- ______________________________________________________________________________
-
-
- 1.53:
-
- The 1.52 release might have allocated chip memory in case a small non-public
- memory chunk was requested even though fast memory would have been
- available. The 1.53 edition will try FAST first. However, note that this has
- the side effect that the small memory pool can never be "virtual". This
- seems to be Ok for me since PoolMem should not play with virtual memory
- anyhow.
-
- ______________________________________________________________________________
-
- 1.52:
-
- Added the "NOCHIP" option, thanks to Dirk Neubauer.
- Found that PoolMem could cause an unnecessary but harmless memory flush if
- chip memory is allocated from the small pool.
- Reworked the main loop of the supervisor task a bit to speed up the PoolMem
- removal procedure.
-
- ______________________________________________________________________________
-
- 1.51:
-
- Some internal cosmetical changes, updated the guide a bit and included a new
- release of ShowMem.
-
- ______________________________________________________________________________
-
- 1.50.1:
-
- Copied the guide on top of the binary, which was therefore not included.
- No other changes.
-
- ______________________________________________________________________________
-
- 1.50:
-
- The patch check was a bit over-critical in the sense that it checked explicit-
- ly whether the library entries where in ROM which is false on machines with
- a (MMU-less) RAM remapped ROM. I'm now checking, alternatively, whether the
- entries go to the exec segment list which should avoid the problem.
- ______________________________________________________________________________
-
- 1.49:
-
- Added a check for patches installed in front of PoolMem. It will now fail in
- case it finds any patches in the memory allocation routines. This rule has
- been valid before, but it seems nobody cared about this point.
- ______________________________________________________________________________
-
- 1.48: (internal release only)
-
- Added even more consistency checks on AllocMem and FreeMem. In case you
- see the new gurus 0x81000015 or 0x81000016, you'd better contact me, or
- check your system for broken programs. Except that, nothing changed.
- ______________________________________________________________________________
-
- 1.47:
-
- The PoolMem memory clear routine is now a bit more effective (slightly).
- Allocations with MEMF_REVERSE set will be no longer taken from the memory
- scratch list. Added a new option KEEPSORTED that implements a slightly
- different scratch management which *might* help to improve the garbage
- collection mechanism under certain circumstances.
-
- Note that there's now a bug-report form in case you encounter problems.
- ______________________________________________________________________________
-
- 1.46:
-
- Made sure that the PoolMem allocated memory headers are always in public
- memory. NOTE THAT THERE IS NO 1.45 RELEASE. SOMEONE WITH A STRANGE SENSE OF
- HUMOUR UPLOADED A TROJAN WITH A FAKED 1.45 RELEASE. DELETE IT IMMEDIATELY AS
- SOON AS YOU SEE IT AND REPLACE IT BY THIS 1.46.
- Updated ShowMem as well.
-
-
- 1.44:
-
- Fixed a minor problem in the allocation function that might have resulted
- in non-optimal memory layout on some boards and could have caused slow-downs.
-
-
- 1.43.1:
-
- Forgot to include the latest release of ShowMem. Oops! Thanks Raphael!
- Note that PoolMem *is not* compatible to MuGuardianAngel!
-
-
- 1.43:
-
- PoolMem does no longer try to pool non-MEMF_PUBLIC memory. This might be
- of importance if virtual memory is introduced.
-
-
- 1.42:
-
- Added the FREEMEMRESULT option to set a result code for FreeMem(). This can
- be used to work around bugs of various programs, check the guide for
- details.
-
- 1.41.3:
-
- Added the RexxSerDevFix archive to the distribution. This patches a bug in
- the rexxserdev.library. Check the guide for details.
-
- 1.41.2:
-
- Fixed the description of the pgs_PatchMem program, added Carl's EMail.
-
- 1.41.1:
-
- Added the pgs_patchmem experimental program. Might help to avoid Photogenics
- crashes, but don't use it permanently. Read the guide first before trying it.
- Thanks goes to Carl Drougge for writing this program, and for allowing me to
- redistribute it.
