3489 5720 d 22 h rimsky /branches/sparc/ More files made conform the US-III specification. (Changes concern mainly TSB.)  
3467 5738 d 19 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 5744 d 4 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 5773 d 0 h decky /branches/sparc/ add sparc branch  
2071 6352 d 20 h jermar /trunk/ (c) versus (C)  
2065 6366 d 19 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
1891 6473 d 19 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).
 
1860 6491 d 22 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 6522 d 1 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.
 
1822 6522 d 5 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 6542 d 22 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6549 d 23 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6571 d 2 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
617 6752 d 18 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 6761 d 21 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6761 d 21 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
531 6762 d 20 h jermar /kernel/trunk/arch/sparc64/include/mm/ sparc64 work.
MMU ASI & virtual addresses definitions.
 
530 6763 d 6 h jermar /kernel/trunk/arch/sparc64/include/mm/ sparc64 work.
TTE (Translation Table Entry) type definitions.
