2044 6369 d 20 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.		  
2043 6369 d 20 h jermar /trunk/kernel/arch/sparc64/src/ Make the sparc64 kernel compile again.  
2038 6370 d 15 h jermar /trunk/kernel/arch/sparc64/ Remove old stuff.  
2037 6370 d 16 h jermar /trunk/kernel/arch/sparc64/include/ Backout change from revision 2034.
sparc64 is not yet ready for get_cycle().		  
2034 6371 d 0 h jermar /trunk/kernel/arch/sparc64/include/ get_cycle() for sparc64.  
2033 6371 d 0 h decky /trunk/kernel/arch/ppc32/include/ get_cycle() for PPC32  
2025 6372 d 15 h jermar /trunk/ Coding style fixes.  
2023 6372 d 18 h decky /trunk/kernel/arch/ add dummy cycle.h  
2018 6372 d 20 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2017 6373 d 0 h decky /trunk/kernel/arch/ia32xen/ update for Xen  
2016 6373 d 1 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 6374 d 18 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 6376 d 19 h decky /trunk/ version bump to Xen 3.0.3 (not fully operational yet)  
2010 6379 d 17 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix comment.  
2009 6379 d 17 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6381 d 18 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2007 6382 d 16 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 6383 d 22 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
2001 6385 d 15 h jermar /trunk/kernel/ Indentation and comment fixes.  
1996 6391 d 19 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.
