*Configure ANYTHINGsize was broken due to not setting R0 to ReadUnsigned IIC ack message uninternationalised OS_Memory was saying we only had 4M of RAM VDU4 scrolling when output was switched to sprite was causing corruption on use of CTRL-J and CTRL-K Default SystemSize CMOS set to 32k Version 5.35, 4.79.2.55.

Detail: Lots of changes since last version, at least the following: * Updated OS timestamp, removed alpha status * Negative INKEY OS version changed to &AA * GraphicsV is now alocated vector number &2A * ROM moved up to &FC000000 * Max application slot increased to 512 Mbytes (for now) * Max size of RMA increased to 256 Mbytes * RMA is now first-created dynamic area (so it gets lowest address after top of application slot) * OS_Memory 10 reimplemeted * New OS_ReadSysInfo 6 values 18-22 added * OS_ReadSysInfo 8 gains flag bit to indicate soft power-off * Misc internal top-bit-set-address fixes * *ChangeDynamicArea can take sizes in megabytes or gigabytes * Magic word "&off" in R0 passed to OS_Reset powers down if possible * Added acceleration: block copy; CLS; text window scroll up; rectangle fill * Disabled LED flashing in page mode (liable to crash) * Masked sprite plot and VDU 5 text avoids reading the screen if possible * Framestore made USR mode accessible * Fix for VDU 5,127 bug - now relies on font definitions being in extreme quarters of memory, rather than bottom half * Allocated 64-bit OS_Convert... SWIs * IIC errors use allocated error numbers * Looks for Dallas RTC before Philips RTC because we're using a Philips NVRAM device with the same ID * Fix to bug that meant the oscillator in the Dallas RTC wasn't enabled * Default mouse type (USB) changed to allocated number * Ram disc max size increased to 128 Mbytes (Ursula merge) and made cacheable for StrongARMs (not XScale) * Branch through zero handler now works in USR mode, by use of a trampoline in the system stack to allow PC-relative register storage * Address exception handler changed to not use 0 as workspace * OS_Memory 13 extended to allow specification of cacheability and access privileges * Added OS_Memory 16 to return important memory addresses * RISCOS_MapInIO() takes cacheable flag in bit 3, access permissions in bits 10 and 11, doubly-mapped flag in bit 20, and access permissions specified flag in bit 21 * Bug fix in last version for application abort handlers didn't quite work; register shuffle required * "Module is not 32-bit compatible" error now reports the module name * Default configured language changed from 10 to 11 (now Desktop again) Version 5.35, 4.79.2.51.

Look for LongCommandLine flag, command line size currently set at 1k. For HAL/32bit builds, the kernel buffer space is at high (top bit set) address, which may break some code using signed comparisons. So *beware* that there may be some latent bugs in old kernel code using these buffers, not yet found. One such bug, in s.Arthur2 found and fixed. Tested moderately on ARM9 desktop build. Lovely to reimplement things I did two and half years ago. Version 5.35, 4.79.2.37. Tagged as 'Kernel-5_35-4_79_2_37'

First attempt at ARM9 support, and general clean-up of old ARM-specific code, now using vectored ARMops. Not tested. Version 5.35, 4.79.2.14. Tagged as 'Kernel-5_35-4_79_2_14'

* Added ARM_IMB and ARM_IMBRange SWIs as recommended by ARMv5. * Some early prototype HAL bits popped in - a lot of source restructuring still to come. * New debug target creates an AIF image with debug information, and translates this into an ASCII object file for the 16702B logic analyser.

Removed DriversInKernel conditional. Detail: If the territory changes or the resource file changes, the kernel will now decache all the cached error blocks so that next time they are required, they will be looked up again. The error cacheing is now a kernel build option and is always set to on. Removed one of the 5 error messages to be cached - it never seems to happen. The remaining 4 are more frequent. Admin: Tested in Ursula build. Cannot be used with HdrSrc 0.94. HdrSrc 0.95 and later is required (or HdrSrc 0.93 and earlier subject to other kernel requirements) Requires MessageTrans 0.42 or later for correct operation when a replacement messages file is loaded. Version 5.32. Tagged as 'Kernel-5_32'

Details: The Kernel will now compile to produce a pure 32-bit system if No26bitCode is set to TRUE. If No26bitCode is FALSE, then the Kernel will be a standard 26-bit Kernel, although some internal changes have taken place to minimise compile switches between the two cases. See Docs.32bit for more technical info. The hardest part was the flood-fill... Other changes: Pointer shape changes now take place on the next VSync, rather than actually WAITING for the VSync. Turning the Hourglass on shouldn't slow your machine down by 5% now :) Lots of really crusty pre-IOMD code removed. Admin: Tested in 32 and 26-bit forms in a limited desktop build. Basically, this will need to see a lot of use to iron out difficulties. I'd like anyone who has a non-frozen project to at least attempt using this Kernel. Version 5.23. Tagged as 'Kernel-5_23'
