      Sort out hard ROM size for HALs with no hard ROM · 6e934a16
      Robert Sprowson authored
      Previously HAL_PhysInfo took one of two routes to get the arrangment table of arrangement table size.
      Reorganised to accept a subreason to allow other physical info to be requested.

      Removed '_' after Video in entry numbers to be consistent with other HAL entry naming, and HAL_VideoFlybackDevice.
      Added IICStatus return numbers to Hdr:HALEntries.
      Stop calling HAL_MonitorLeadID as only IOMD implemented it - just guess VGA until the graphics driver says otherwise.

      Sort out SetBorder · fe354937
      Robert Sprowson authored
      NewReset.s:
      The one remaining use of SetBorder was to denote the user asked for and got a CMOS reset, which in the HAL case emitted a warning because setting the border is potentially complicated/slow.
      To solve this, the reset is noted and replaces the normal RISC OS banner with a warning message. The behaviour and text for this comes from the BBC Master, though the escape key is used in place of break since a reset isn't actually needed.
      Moved the unused cputable inside its corresponding switch.
      Two occurrences of WriteS_Translated would have executed the message in the V=1 case.
      KernelWS/Resources:
      Flag added to workspace, translation added to messages files.
      Heapman.s:
      Commented out use of SetBorder removed.
      Kernel.s:
      SetBorder macro removed.
      Middle.s:
      Switched out use of SetBorder removed.
      Super1.s:
      Conditional WriteS_Translated would try to execute the message in the opposite condition case.

      Add compressed ROM support. Make more use of ARMv5+ instructions. Other misc tweaks. · 538f3c24
      Jeffrey Lee authored
      Detail:
        hdr/OSEntries, s/HAL, s/Kernel - Add compressed ROM support.
        With the current scheme, a compressed ROM will have everything except the HAL and kernel compressed.
        During the keyboard scan period the kernel will allocate some temporary decompression workspace and call the decompression stub that was appended to the ROM.
        The decompression stub is expected to perform in-place decompression of the ROM. Once decompression is complete the workspace will be freed and the page tables updated to make the ROM image readonly.
        It's the HAL's responsibility to make sure any compressed ROM is located in an area of physically contiguous RAM large enough to hold the uncompressed image.
        More info here: http://www.riscosopen.org/wiki/documentation/show/Compressed%20ROMs
        Makefile, h/OSEntries - Add C export of hdr/OSEntries
        hdr/HALDevice - Add device ID for Tungsten video device. Convert tabs to spaces for consistency.
        hdr/HALEntries, s/NewReset - Moved KbdFlag_* definitions to hdr/HALEntries so HALs can use them in their keyboard scan code
        s/ArthurSWIs, S/HAL, s/HeapSort, s/Kernel, s/MemInfo, s/Middle, s/NewIRQs, s/TickEvents, s/vdu/vdugrafb - Make use of BLX, BFI and long multiplies if the CPU supports them. Don't support SWI calls from thumb mode if the CPU doesn't support thumb.
        s/HAL - Made the LDMIA in Init_MapInRAM more sensible (register order was backwards). The old code did work, but wasn't doing what the comments described. Removed unused/unfinished HAL_Write0 function. Improve RISCOS_LogToPhys to check L1PT for any section mappings if the logical_to_physical call fails
        s/ModHand - Save one instruction by using ADR instead of MOV+ADD to compute lr
        s/NewReset, s/PMF/key - Pass L1PT to HAL_Reset to allow machines without hardware reset (e.g. IOMD) to perform resets by manually disabling the MMU and restarting the ROM
        s/vdu/vdudriver, s/vdu/vdugrafv - Use GVEntry macro borrowed from NVidia module for setting up the GraphicsV jump table. Make GraphicsV_ReadPaletteEntry call HAL_Video_ReadPaletteEntry if left unclaimed. Fixup GV_Render to only call HAL_Video_Render if the HAL call is implemented.

      Improve heap manager. Add heap testbed. Add dummy implementation of some OS_ScreenMode reason codes.
      
      Detail:
        s/HeapMan, hdr/KernelWS - Heap manager improvements:
          - Errors generated by interrupted heap operations that are forced to complete by a OS_Heap call from the background are now cached in kernel workspace until the foreground task is resumed. This prevents them from being potentially overwritten by MessageTrans running out of background error buffers.
          - Added new OS_Heap reason code, #7 - Get area aligned. This allows areas of memory to be allocated at specific (power-of-2) alignments, and optionally without crossing a given (power-of-2) boundary. Alignment & boundary calculations are performed using logical addresses.
          - Removed the limitation that all free and allocated blocks must be a multiple of 8 bytes in length. This change was required in order to allow OS_Heap 7 to function correctly. Now the only requirements are that blocks must be multiples of 4 bytes in length, at 4 byte alignment, with a minimum length of 8 bytes. 4 extra padding bytes may still be added to the end of allocations in order to avoid creating 4-byte free blocks.
        s/HeapMan, TestSrc/HeapTest/Makefile, TestSrc/HeapTest/c/testbed, TestSrc/HeapTest/s/asm - Added heap testbed program. Can either use the OS_Heap SWI or directly include a copy of the Kernel's heap manager sources.
        s/vdudecl, s/vduswis - Added dummy implementations of OS_ScreenMode 4, 5 and 6. This prevents the Wimp generating lots of "Unknown OS_ScreenMode reason code" errors when redrawing the screen.
        s/Arthur3, s/Oscli - Moved dotstring closer to where it's used to avoid "ADRL out of range" errors in Tungsten build
      Admin:
        Tested in OMAP3 ROM & Tungsten ROM softload.
        Heap testbed successfully performed over 400 million heap ops, so there shouldn't be any serious bugs in the new code (touch wood)

          - Also only look for 7 cache levels, since level 8 doesn't exist according to the ARMv7 ARM.

      Add zero page relocation support · 2247d8e9
      Jeffrey Lee authored
      Detail:
        A whole mass of changes to add high processor vectors + zero page relocation support to the Cortex branch of the kernel
        At the moment the code can only cope with two ZeroPage locations, &0 and &FFFF0000. But with a bit more tweaking those restrictions can probably be lifted, allowing ZeroPage to be hidden at almost any address (assuming it's fixed at compile time). If I've done my job right, these restrictions should all be enforced by asserts.
        There's a new option, HiProcVecs, in hdr/Options to control whether high processor vectors are used. When enabling it and building a ROM, remember:
        * FPEmulator needs to be built with the FPEAnchor=High option specified in the components file (not FPEAnchorType=High as my FPEmulator commit comments suggested)
        * ShareFS needs unplugging/removing since it can't cope with it yet
        * Iyonix users will need to use the latest ROOL boot sequence, to ensure the softloaded modules are compatible (OMAP, etc. don't really softload much so they're OK with older sequences)
        * However VProtect also needs patching to fix a nasty bug there - http://www.riscosopen.org/tracker/tickets/294
        The only other notable thing I can think of is that the ProcessTransfer code in s/ARM600 & s/VMSAv6 is disabled if high processor vectors are in use (it's fairly safe to say that code is obsolete in HAL builds anyway?)
        Fun challenge for my successor: Try setting ZeroPage to &FFFF00FF (or similar) so its value can be loaded with MVN instead of LDR. Then use positive/negative address offsets to access the contents.
        File changes:
        - hdr/ARMops - Modified ARMop macro to take the ZeroPage pointer as a parameter instead of 'zero'
        - hdr/Copro15ops - Corrected $quick handling in myISB macro
        - hdr/Options - Added ideal setting for us to use for HiProcVecs
        - s/AMBControl/allocate, s/AMBControl/growp, s/AMBControl/mapslot, s/AMBControl/memmap, s/AMBControl/service, s/AMBControl/shrinkp, s/Arthur2, s/Arthur3, s/ArthurSWIs, s/ChangeDyn, s/ExtraSWIs, s/HAL, s/HeapMan, s/Kernel, s/MemInfo, s/Middle, s/ModHand, s/MoreSWIs, s/MsgCode, s/NewIRQs, s/NewReset, s/Oscli, s/PMF/buffer, s/PMF/IIC, s/PMF/i2cutils, s/PMF/key, s/PMF/mouse, s/PMF/osbyte, s/PMF/oseven, s/PMF/osinit, s/PMF/osword, s/PMF/oswrch, s/SWINaming, s/Super1, s/SysComms, s/TickEvents, s/Utility, s/vdu/vdu23, s/vdu/vdudriver, s/vdu/vdugrafl, s/vdu/vdugrafv, s/vdu/vdupalxx, s/vdu/vdupointer, s/vdu/vduswis, s/vdu/vduwrch - Lots of updates to deal with zero page relocation
        - s/ARM600 - UseProcessTransfer option. Zero page relocation support. Deleted pre-HAL ClearPhysRAM code to tidy the file up a bit.
        - s/ARMops - Zero page relocation support. Set CPUFlag_HiProcVecs when high vectors are in use.
        - s/KbdResPC - Disable compilation of dead code
        - s/VMSAv6 - UseProcessTransfer option. Zero page relocation support.
      Admin:
        Tested with OMAP & Iyonix ROM softloads, both with high & low zero page.
        High zero page hasn't had extensive testing, but boot sequence + ROM apps seem to work.

      Add new OS_ReadSysInfo 6 items. Change naming of PublicWS values. · d2c62e16
      Jeffrey Lee authored
      Detail:
        s/Middle - Added some new OS_ReadSysInfo 6 items which are needed by the zero page relocation kernel. Also duplicated some existing entries to avoid conflicts with ROL's allocations.
        hdr/OSRSI6, Makefile - New header listing OS_ReadSysInfo 6 items
        hdr/PublicWS - Duplicated the workspace definitions for &0-&4000, but with a 'Legacy_' prefix to their names. Also added some new entries as needed by the zero page relocation kernel. Once existing modules have been updated to use OS_ReadSysInfo 6 & the Legacy_ definitions, the old defs will be removed.
        hdr/KernelWS - Removed 'Export_' prefix from all the exported workspace values, since the kernel can now use the original names directly
        hdr/Options - Dummy HiProcVecs option so merging things will be a bit cleaner

      Update the method the HAL kernel uses to determine the UtilityModule & ROM dates · e249f5da
      Jeffrey Lee authored
      Detail:
        Three main changes:
        * On odd-numbered (i.e. development) versions of the module, the UtilityModule will now take its date from the VersionNum file instead of using a hard-coded date
        * All build versions now look for the new "extended ROM footer" (as created by romlinker 0.04+) at the end of the ROM image and use it to determine the ROM build date for return by OS_ReadSysInfo 9,2. Failing to find the build date in the footer will cause OS_ReadSysInfo 9,2 to return 0.
        * On odd-numbered versions, OS_Byte 0 will now use the ROM build date (as found in the extended footer) to generate the error block that's returned to the user. This seems OK as the PRM describes OS_Byte 0 as returning the "creation date of the operating system". Plus it's a convenient way of getting the ROM build date into the Switcher, since the switcher uses OS_Byte 0. If the extended footer can't be found (or if the string isn't initialised yet, e.g. before Service_PostInit) the code falls back to a hard-coded string containing the date from the VersionNum file.
        File changes:
        Makefile - Updated to not create the obsolete Time+Date file (previously used for the ROM build date)
        Version - Use date from VersionNum file for development builds
        hdr/Options - New UseNewFX0Error variable/option to make it easy to check which OS_Byte 0 variant should be enabled
        hdr/KernelWS - Added new string buffers & extended ROM footer pointer to workspace
        s/Middle - Updated OS_ReadSysInfo 9 code, and added utility functions for searching the extended ROM footer for certain tags
        s/NewReset - Added a couple of calls to initialise the new string buffers just prior to Service_PostInit. This is required since OS_Byte/OS_ReadSysInfo shouldn't enable interrupts, but date conversion relies on the Territory module, which may enable interrupts.
        s/PMF/osbyte - Updated OS_Byte 0 code
      Admin:
        Tested in Tungsten ROM, with and without the extended footer present.

      Kernel fixes for ARMv6 · e5f1d1e5
      Jeffrey Lee authored
      Detail:
        hdr/ARMops - Amended ARMvF description to state that an ARMvF CPU can be ARMv6 or ARMv7
        s/ARMops - Move ARM11JZF_S CPUDesc to KnownCPUTable_Fancy, since it's ARMvF. Update ARM_Analyse_Fancy to detect whether ARMv6 or ARMv7 style cache control is in use, and react accordingly.
        s/HAL - Simplified system control register/MMUC initialisation. There are now just two types of setup - one for ARMv3-ARMv5 and one for ARMv6-ARMv7. Modified HAL_InvalidateCache_ARMvF to use the appropriate cache flush instructions depending on whether it's an ARMv6 or ARMv7 style cache.
      Admin:
        S3C6410 and other ARMv6 machines should work now.
        Tested on BB-xM rev A2.

      Add OS_ReadSysInfo reason codes 11 (read debug info) & 12 (read extended machine ID) · e42119c8
      Jeffrey Lee authored
      Detail:
        OS_ReadSysInfo 10 is left unimplemented since it's a bit fiddly for us.
        OS_ReadSysInfo 11 is compatible with ROL's implementation, exposing HAL_DebugTX and HAL_DebugRX if the HAL provides them.
        See here for 10,11 docs: http://select.riscos.com/prm/core/osreadsysinfo.html
        OS_ReadSysInfo 12 is a new call to return the 'extended machine ID', to allow the HAL to specify the format & validity of the ID.
        If the HAL responds to the new HAL_ExtMachineID call then it's assumed that no old-style machine ID is present. The Kernel will generate an old-style ID using the contents of the extended ID, and use that with OS_ReadSysInfo 2/5.
        New software should use OS_ReadSysInfo 12 in preference to 2/5.
        s/Middle - Updated OS_ReadSysInfo SWI
        s/PMF/osinit - New old-style machine ID initialisation code
        hdr/HALEntries - Added new HAL_ExtMachineID entry

      Update OS_IICOp to support multiple IIC buses · 327d3980
      Jeffrey Lee authored
      Detail:
        OS_IICOp (and in turn, RISCOS_IICOpV) now treat the top byte of R1 as containing the IIC bus number, allowing multiple buses to be used.
        hdr/KernelWS - Changed workspace a bit so that the kernel can support up to IICBus_Count buses (currently 3), each with its own IICBus_* block.
        s/HAL - Update Reset_IRQ_Handler to cope with interrupts from all IIC buses instead of just the first. Fix/update RISCOS_IICOpV description.
        s/NewIRQs - Update InitialiseIRQ1Vtable to set up interrupt handlers for all IRQ-supporting IIC buses
        s/NewReset - Get rid of the IICAbort call that was just before IICInit. IICInit now calls IICAbort itself.
        s/PMF/IIC - Bulk of the changes. Code now uses the IICBus_ structures instead of the IICStatus and IICType variables. Re-entrancy code has been updated to take into account the possiblity of multiple buses; when OS_IICOp calls are nested, the IIC transfers will be added to bus-specific queues instead of all going in the same queue. However only one queue will be processed at a time.
        s/ChangeDyn - Workspace shuffling means a couple of MOV's needed to be swapped with LDR's when getting immediate constants
      Admin:
        Tested with OMAP & IOMD ROM builds.
        Both high & low-level bus types seem to work OK, along with re-entrancy, both on the same bus and on a different bus.

      Fix some issues preventing the Cortex kernel from being used on non-Cortex machines · e718080c
      Jeffrey Lee authored
      Detail:
        hdr/Options - ARM6support and GetKernelMEMC values are now derived from the value of MEMM_Type
        s/ARMops, s/HAL - Code to detect and handle ARMv7 CPUs is now only enabled when using VMSAv6 MMU model. Saves us from having to deal with lack of myIMB, myDSB, etc. implementations on pre-ARMv6.
        s/HAL - Removed some debug code
        s/NewReset - Fix bug spotted by Tom Walker where R12 wasn't being restored by LookForHALRTC if a non-HAL RTC had already been found
        s/AMBControl/memmap - correct the assert clause that was checking that &FFE are the correct L2PT protection bits for non-VMSAv6 machines
