2018 6364 d 1 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2017 6364 d 5 h decky /trunk/kernel/arch/ia32xen/ update for Xen  
2016 6364 d 5 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 6365 d 22 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 6368 d 0 h decky /trunk/ version bump to Xen 3.0.3 (not fully operational yet)  
2010 6370 d 21 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix comment.  
2009 6370 d 22 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6372 d 23 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2007 6373 d 21 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 6375 d 3 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
2001 6376 d 20 h jermar /trunk/kernel/ Indentation and comment fixes.  
1996 6383 d 0 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 6383 d 5 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6383 d 6 h decky /trunk/ make framebuffer code more generic  
1988 6384 d 20 h jermar /trunk/kernel/arch/sparc64/src/mm/ Update comment and move initialization code away from application processor codepath.  
1987 6384 d 23 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 6385 d 3 h decky /trunk/kernel/arch/sparc64/src/drivers/ The FFB framebuffer looks more like 32b  
1984 6385 d 23 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller		  
1983 6387 d 2 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.		  
1982 6387 d 6 h jermar /trunk/ Modify the sparc64 startup code to not cause MMU traps before it takes over the TLB and
the trap table. Fix several PA2KA and KA2PA omittions or errors. Fix configuration to pass
the DEFS variable along.
