1852 6471 d 0 h jermar /trunk/kernel/ sparc64 work.
Bunch of changes in preparation for sparc64 mm and userspace support.
Fix alignment of hardcoded_* variables in linker script.		  
1823 6496 d 3 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.		  
1822 6496 d 8 h jermar /trunk/ sparc64 work.
1. Formatting fixes.
2. When writing to DMMU ASI's, simple membar() can be used in place of flush().
3. Substantial changes in the way the TLB is taken over.
4. Remove unneeded functions.

This is the first revision that also runs on a real world Ultra 5 with UltraSPARC IIi
processor.

Note that 3. needs further work as the current implementation depends on the fact
that the compiler will use registers for local variables in take_over_tlb_and_tt().
Rewrite of that function into assembly is to follow.		  
1792 6514 d 21 h jermar /trunk/ Move functionality of tlb_arch_init() to take_over_tlb_and_tt().
Call take_over_tlb_and_tt() very early after the kernel starts
executing.		  
1790 6515 d 1 h jermar /trunk/ Remove OpenFirmware calls from kernel/ entirely.

Switch the sparc64 port to use bootinfo.

Copy memcpy from boot/ to sparc64 kernel/ and
adjust it for memcpy_from/to_uspace.		  
1789 6515 d 4 h jermar /trunk/ Fix ofw_memmap() in boot infrastructure.
The cell size is 32-bit and not equal sizeof(ofw_arg_t).
Define architecture dependant #address-cells and #size-cells for cases
the respective properties are missing in the OpenFirmware device tree.
The algorithm now works both for ppc32 and sparc64.

Add memmap_t, screen_t and keyboard_t to sparc64 bootinfo structure.
Be more verbose during sparc64 boot.

Move ALIGN_UP to generic part of boot/.

Change header guards in several places so that they don't contain double underscore.		  
1787 6517 d 1 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1784 6517 d 22 h jermar /kernel/trunk/ Sync OpenFirmware functionality with boot.
Random cleanup.		  
1777 6524 d 4 h jermar /kernel/trunk/ Make sparc64 kernel assume it is loaded by our loader.  
895 6650 d 22 h jermar /kernel/trunk/ sparc64 work.
Very raw and fragile preliminary standalone keyboard support - polling mode only.
Because of a workaround in Simics, the scan codes are the same as on ia32.		  
867 6656 d 4 h jermar /kernel/trunk/ Move OFW functionality of ppc32 memory_init to genarch so that the code can also be used by sparc64.
sparc64 is now close to broken as it lacks functionality to provide identity mapping for the whole phyisical memory.		  
847 6661 d 1 h jermar /kernel/trunk/arch/sparc64/ Improve comments in start.S.  
846 6661 d 2 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Relocate kernel to 4M.		  
534 6735 d 23 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6736 d 0 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
529 6738 d 3 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add dummy trap tables.		  
501 6748 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
426 6771 d 5 h jermar /SPARTAN/trunk/ sparc64 work.
Add context_save(), context_set() and context_restore().
Remove putchar() definition from ofw.c.
Add sparc64 putchar().
Add ppc32 putchar() (i.e. the original ofw.c putchar()).
Make arg.h use the builtin va_* constructs.		  
424 6772 d 5 h jermar /SPARTAN/trunk/ sparc64 work.
Link kernel with load address 0x4000.
Add fragment of Linux image header to force SILO to always load the kernel at 0x4000.
Adjust ofw.h and ofw.c to work also on sparc64.		  
420 6775 d 20 h jermar /SPARTAN/trunk/arch/sparc64/ Small sparc64 changes.
Start native boot loader.
