3489 5685 d 1 h rimsky /branches/sparc/ More files made conform the US-III specification. (Changes concern mainly TSB.)  
3467 5702 d 23 h rimsky /branches/sparc/ SMP and CPU initialiation modified to work even with Serengeti OFW tree layout; support for output to the Simics CLI console added (see my blog); some header files modified to conform US-III definition. Now HelenOS (on the sample configuration - usiii.simics) is able to run some userspace tasks.  
3440 5708 d 7 h rimsky /branches/sparc/kernel/arch/sparc64/ TLB modifications in order to make functions tlb_print and tlb_invalidate_all work correctly in US-III.  
3343 5737 d 3 h decky /branches/sparc/ add sparc branch  
2071 6316 d 23 h jermar /trunk/ (c) versus (C)  
2065 6330 d 22 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
1891 6437 d 22 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1860 6456 d 1 h jermar /trunk/kernel/ A lot of untested sparc64 stuff:
- Write ASID to hardware when a thread is about to run in userspace.
- Add userspace() and switch_to_userspace() functions.
- Handle special cases when the userspace spill/fill handler causes MMU trap.
- Resolve some TODOs in the existing sparc64 code.
- sparc64 has now C99 compliant header guards.
- Formatting and indentation fixes.		  
1823 6486 d 4 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.		  
1822 6486 d 9 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.		  
1787 6507 d 2 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6514 d 3 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6535 d 6 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
617 6716 d 21 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Support for TLB Demap operations.
Add tlb_invalidate(), tlb_invalidate_asid() and tlb_invalidate_page() (latter two are broken as they ignore asid).		  
534 6726 d 0 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6726 d 1 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
531 6726 d 23 h jermar /kernel/trunk/arch/sparc64/include/mm/ sparc64 work.
MMU ASI & virtual addresses definitions.		  
530 6727 d 9 h jermar /kernel/trunk/arch/sparc64/include/mm/ sparc64 work.
TTE (Translation Table Entry) type definitions.
