2131 6488 d 5 h decky /branches/ add development branches  
2076 6552 d 10 h jermar /trunk/kernel/ Beat the implicit illegal virtual alias created by reusing userspace frames.
In the anonymous and ELF backends, if the architecture has virtually indexed D-cache,
selectively flush cachelines belonging to the frame being freed.
This fixes Ticket #20.
 
2071 6554 d 2 h jermar /trunk/ (c) versus (C)  
2015 6593 d 2 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 6598 d 1 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6600 d 2 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.
