2045 6415 d 6 h jermar /trunk/kernel/arch/sparc64/include/ Fix comment.  
2044 6415 d 6 h jermar /trunk/kernel/arch/sparc64/ On sparc64's tick interrupt, adjust the TICK_COMPARE register instead of the TICK
register. The TICK register now increments linearily and can be used by the get_cycle()
function.		  
2038 6416 d 2 h jermar /trunk/kernel/arch/sparc64/ Remove old stuff.  
2037 6416 d 2 h jermar /trunk/kernel/arch/sparc64/include/ Backout change from revision 2034.
sparc64 is not yet ready for get_cycle().		  
2034 6416 d 10 h jermar /trunk/kernel/arch/sparc64/include/ get_cycle() for sparc64.  
2025 6418 d 1 h jermar /trunk/ Coding style fixes.  
2023 6418 d 5 h decky /trunk/kernel/arch/ add dummy cycle.h  
2015 6420 d 4 h jermar /trunk/ Rework support for virtually indexed cache.
Instead of repeatedly flushing the data cache, which was a huge overkill, refuse to create an illegal address alias
in the kernel (again) and allocate appropriate page color in userspace instead. Extend the detection also to
SYS_PHYSMEM_MAP syscall.

Add support for tracking physical memory areas mappable by SYS_PHYSMEM_MAP.

Lots of coding style changes.		  
2009 6425 d 3 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6427 d 4 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2007 6428 d 3 h jermar /trunk/kernel/ Introduce page colors. So far, only sparc64 uses correct page color bits. Other architectures have a dummy define
specifying zero bits for a page color.

There is a new check of page color in as_area_share(). Because of lack of support for this in the userspace, the
check has been #ifef'ed out.		  
2003 6429 d 9 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1984 6440 d 5 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller		  
1978 6442 d 4 h jermar /trunk/ sparc64 code to support physical memory that starts on non-zero addresses.
Still needs to be tested on systems with such setup.		  
1976 6448 d 10 h jermar /trunk/kernel/arch/sparc64/ sparc64 context does not have to include the CLEANWIN register.  
1954 6464 d 3 h jermar /trunk/ Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.		  
1949 6468 d 12 h jermar /trunk/kernel/arch/ Remove notes about automatically generated context_offset.h
and replace it with a proper copyright notice.		  
1948 6468 d 14 h jermar /trunk/kernel/ Remove broken, outdated and unused gencontext.c utilities.  
1946 6471 d 2 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
- Improve panic screen on data_access_exception
by dumping contents of DSFSR and DSFAR.
- Change the FHC enable interrupt code to only
set the IMAP_V bit.		  
1942 6472 d 4 h jermar /trunk/ Convert ia64 to the new IRQ and notification scheme.
