2860 6098 d 0 h cejka /trunk/ Context handling unified for sparc64.  
2071 6552 d 0 h jermar /trunk/ (c) versus (C)  
1976 6619 d 6 h jermar /trunk/kernel/arch/sparc64/ sparc64 context does not have to include the CLEANWIN register.  
1864 6687 d 21 h jermar /trunk/ sparc64 update.
- Prototype userspace layer implementation that
at least relates to sparc64 and compiles cleanly.
- Fixes for kernel's preemptible_handler and code
related to running userspace.
- Enable userspace. Several dozen instructions
are now run in userspace! We are pretty near
the userspace milestone for sparc64.
 
1787 6742 d 2 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
666 6937 d 23 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 6943 d 21 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 6945 d 22 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.
 
534 6961 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6961 d 1 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
529 6963 d 4 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add dummy trap tables.
 
528 6964 d 0 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 6964 d 6 h jermar /kernel/trunk/ saprc64 work.
Perform leaf-procedure optimization for context_save and context_restore.
 
526 6964 d 7 h jermar /kernel/trunk/ sparc64 work.
No need to save/restore local registers.
 
525 6964 d 10 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add stack.h.
 
501 6973 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
472 6986 d 6 h jermar /SPARTAN/trunk/ Changes in build system.
For .S targets, always do -D__ASM__.
Remove unnecessary #define __ASM__ from various *.S files.
At the end of build, generate disassembler dump for kernel.raw.

ia64 work.
Better General Exception handler.
 
428 6996 d 2 h jermar /SPARTAN/trunk/arch/sparc64/src/ sparc64 work.
In context_save() and context_restore(), reserve 128 bytes on stack for save area.
 
426 6996 d 7 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.
