2860 5857 d 7 h cejka /trunk/ Context handling unified for sparc64.  
2071 6311 d 7 h jermar /trunk/ (c) versus (C)  
1976 6378 d 13 h jermar /trunk/kernel/arch/sparc64/ sparc64 context does not have to include the CLEANWIN register.  
1949 6398 d 14 h jermar /trunk/kernel/arch/ Remove notes about automatically generated context_offset.h
and replace it with a proper copyright notice.		  
1888 6436 d 10 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1851 6460 d 14 h jermar /trunk/kernel/ sparc64 work.
Define the istate structure.
Move the identity-mapping handler to assembly.
Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it.

Little bit of formatting and indentation.		  
1787 6501 d 9 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1702 6529 d 13 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
860 6642 d 3 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
666 6697 d 6 h jermar /kernel/trunk/ sparc64 work.
Fix clean_window trap handler so that it clears output registers instead of input registers!
Fix interrupt handlers to save global registers.		  
657 6703 d 4 h jermar /kernel/trunk/ sparc64 work.
Context again. It turns out, according to SCD 2.4, that registers that didn't have to be saved were saved (%o1 - %o5) and
registers that had to be saved were not saved (%i0 - %i5, %l0 - %l7).		  
650 6705 d 5 h jermar /kernel/trunk/ sparc64 work.
Implement interrupt_disable(), interrupt_enable(), interrupt_restore() and interrupt_read() functions.
Fix context save/restore to save/restore register %i7.

528 6723 d 7 h jermar /kernel/trunk/ sparc64 work.
The context_save/context_restore needed two other improvements.
First, storing of %fp because of window_fills.
Second, flushing all active windows before CONTEXT_LOAD to make CWP - 1 the overlap window.		  
527 6723 d 14 h jermar /kernel/trunk/ saprc64 work.
Perform leaf-procedure optimization for context_save and context_restore.		  
526 6723 d 14 h jermar /kernel/trunk/ sparc64 work.
No need to save/restore local registers.		  
501 6732 d 12 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.
