2023 6360 d 9 h decky /trunk/kernel/arch/ add dummy cycle.h  
2018 6360 d 10 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2017 6360 d 14 h decky /trunk/kernel/arch/ia32xen/ update for Xen  
2016 6360 d 15 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 6362 d 8 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.		  
2014 6364 d 10 h decky /trunk/ version bump to Xen 3.0.3 (not fully operational yet)  
2010 6367 d 7 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix comment.  
2009 6367 d 7 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6369 d 8 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2007 6370 d 6 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 6371 d 13 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
2001 6373 d 5 h jermar /trunk/kernel/ Indentation and comment fixes.  
1996 6379 d 10 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 6379 d 14 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6379 d 16 h decky /trunk/ make framebuffer code more generic  
1988 6381 d 6 h jermar /trunk/kernel/arch/sparc64/src/mm/ Update comment and move initialization code away from application processor codepath.  
1987 6381 d 9 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 6381 d 12 h decky /trunk/kernel/arch/sparc64/src/drivers/ The FFB framebuffer looks more like 32b  
1984 6382 d 8 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller		  
1983 6383 d 12 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.
