2019 6538 d 7 h decky /trunk/kernel/ prepare for new test infrastructure  
2018 6538 d 8 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2017 6538 d 11 h decky /trunk/kernel/arch/ia32xen/ update for Xen  
2016 6538 d 12 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 6540 d 5 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 6542 d 7 h decky /trunk/ version bump to Xen 3.0.3 (not fully operational yet)  
2012 6543 d 3 h jermar /trunk/ Eliminate confusion between SYS_MAP_PHYSMEM and sys_physmem_map.
The syscall is to be called SYS_PHYSMEM_MAP from now on and the functions that participate in its implementation are
called *physmem_map().		  
2011 6544 d 9 h decky /trunk/kernel/ resolve ticket #4  
2010 6545 d 4 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix comment.  
2009 6545 d 4 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6547 d 5 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2007 6548 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.		  
2005 6549 d 10 h decky /trunk/ update rd  
2004 6549 d 10 h decky /trunk/kernel/generic/include/ cleanup  
2003 6549 d 10 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
2002 6549 d 12 h decky /trunk/kernel/generic/ rd work  
2001 6551 d 3 h jermar /trunk/kernel/ Indentation and comment fixes.  
2000 6551 d 14 h decky /trunk/kernel/ move files to more proper locations  
1999 6551 d 15 h decky /trunk/ start RAM disk support  
1996 6557 d 7 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.
