2034 6501 d 13 h jermar /trunk/kernel/arch/sparc64/include/ get_cycle() for sparc64.  
2025 6503 d 4 h jermar /trunk/ Coding style fixes.  
2023 6503 d 8 h decky /trunk/kernel/arch/ add dummy cycle.h  
2016 6503 d 14 h jermar /trunk/kernel/arch/sparc64/src/mm/ The D-cache line size is actually 32 bytes on UltraSPARC II, IIi (and also IIe).  
2015 6505 d 7 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.		  
2010 6510 d 6 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix comment.  
2009 6510 d 6 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6512 d 7 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2007 6513 d 5 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 6514 d 12 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
2001 6516 d 5 h jermar /trunk/kernel/ Indentation and comment fixes.  
1996 6522 d 9 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.		  
1994 6522 d 14 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6522 d 15 h decky /trunk/ make framebuffer code more generic  
1988 6524 d 5 h jermar /trunk/kernel/arch/sparc64/src/mm/ Update comment and move initialization code away from application processor codepath.  
1987 6524 d 8 h jermar /trunk/kernel/arch/sparc64/src/ Take the possible difference between kernel and physical address into account in TSB and userspace window buffer
allocation and deallocation code.		  
1986 6524 d 12 h decky /trunk/kernel/arch/sparc64/src/drivers/ The FFB framebuffer looks more like 32b  
1984 6525 d 8 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller		  
1983 6526 d 11 h jermar /trunk/kernel/arch/sparc64/src/mm/ sparc64 work:
- fix computation of the frame allocator configuration frame
- mark the first physical frame unavailable, no matter what is its address

Because of that, we can now boot past the frame_arch_init() on the Ultra 60 now.		  
1982 6526 d 15 h jermar /trunk/ Modify the sparc64 startup code to not cause MMU traps before it takes over the TLB and
the trap table. Fix several PA2KA and KA2PA omittions or errors. Fix configuration to pass
the DEFS variable along.
