2089 6328 d 7 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2082 6334 d 7 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2078 6335 d 3 h jermar /trunk/kernel/arch/sparc64/src/ When invalidating entire TLBs on sparc64, make sure to also invalidate any (locked) global entries.
This fixes Ticket #21.
Fix a comment in start.S stating that the kernel installs a global entry for itself. All entries installed by the kernel
are local to some memory context.		  
2076 6337 d 8 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 6339 d 0 h jermar /trunk/ (c) versus (C)  
2067 6349 d 6 h jermar /trunk/kernel/ More formatting changes.  
2058 6365 d 9 h jermar /trunk/kernel/arch/sparc64/src/ Improve comments.  
2055 6366 d 12 h jermar /trunk/kernel/arch/sparc64/src/ sparc64 work:
- No need to lock kernel stack and userspace window buffer into DTLB.		  
2054 6366 d 22 h jermar /trunk/kernel/ Fix important comment in kernel/arch/sparc64/src/proc/scheduler.c.

Improve framebuffer code.

Formatting and indentation fixes.		  
2049 6370 d 8 h jermar /trunk/kernel/arch/sparc64/src/ More formatting and indentation changes.  
2048 6371 d 1 h jermar /trunk/ Formatting and indentation changes.  
2044 6373 d 2 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 6373 d 2 h jermar /trunk/kernel/arch/sparc64/src/ Make the sparc64 kernel compile again.  
2038 6373 d 21 h jermar /trunk/kernel/arch/sparc64/ Remove old stuff.  
2016 6376 d 7 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 6378 d 0 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 6382 d 23 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix comment.  
2009 6382 d 23 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6385 d 0 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2001 6388 d 21 h jermar /trunk/kernel/ Indentation and comment fixes.
