3770 5592 d 18 h rimsky /branches/sparc/ Working on Niagara port - TLB initialization, MMU fault status area initialization, hypercall enhancement, modified tick.c so that the (hyperprivileged) TICK register does not have to be accessed. Now the initialization phase proceeds, but some parts of it are omitted for now (e.g. CPU initialization).  
3742 5600 d 4 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3489 5676 d 21 h rimsky /branches/sparc/ More files made conform the US-III specification. (Changes concern mainly TSB.)  
3343 5728 d 23 h decky /branches/sparc/ add sparc branch  
2266 6218 d 21 h jermar /trunk/kernel/arch/sparc64/src/mm/ Add few assertions to tsb.c and clean it up a little bit.  
2161 6237 d 20 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix TSB bug during TSB refill.
When one wants to enable a TSB entry, he or she should set the
entry invalid bit to false, as opposed to setting it to true.		  
2141 6239 d 16 h jermar /trunk/ The Ultimate Solution To Illegal Virtual Aliases.
It is better to avoid them completely than to fight them.
Switch the sparc64 port to 16K pages. The TLBs and TSBs
continue to operate with 8K pages only. Page tables and
other generic parts operate with 16K pages.

Because the MMU doesn't support 16K directly, each 16K
page is emulated by a pair of 8K pages. With 16K pages,
illegal aliases cannot be created in 16K D-cache.		  
2089 6298 d 2 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6308 d 19 h jermar /trunk/ (c) versus (C)  
2048 6340 d 21 h jermar /trunk/ Formatting and indentation changes.  
2009 6352 d 19 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2001 6358 d 17 h jermar /trunk/kernel/ Indentation and comment fixes.  
1996 6364 d 21 h jermar /trunk/kernel/ Add option to compile the sparc64 kernel without the TTE_CV bit support.
The bit is not used by default now.
Enabling it may theoretically lead to physical memory inconsistencies until code that
mitigates the problem is written.		  
1960 6390 d 19 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix the following bug:

Ticket #3 data_access_exception after killing task on sparc64		  
1917 6408 d 20 h jermar /trunk/ sparc64 work:
- hw_map() can now support up to 8M requests
- CPU stacks are now locked in DTLB of the respective processor
- kernel in the boot phase no longer relies on the stack provided by OpenFirmware
- instead of of doing FLUSHW during kernel startup, simply set the
window state registers to the wanted state
- NWINDOW -> NWINDOWS
- Add/fix some comments and copyrights.		  
1891 6429 d 18 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1889 6430 d 20 h jermar /trunk/kernel/ Fix bug in mm/as.c:
- as_area_destroy() should not work with AS but as

sparc64 work:
- start implementing TSB support
