2016 6383 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 6385 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.		  
2010 6390 d 4 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix comment.  
2009 6390 d 4 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6392 d 5 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2001 6396 d 2 h jermar /trunk/kernel/ Indentation and comment fixes.  
1996 6402 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.		  
1994 6402 d 12 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6402 d 13 h decky /trunk/ make framebuffer code more generic  
1988 6404 d 3 h jermar /trunk/kernel/arch/sparc64/src/mm/ Update comment and move initialization code away from application processor codepath.  
1987 6404 d 6 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 6404 d 10 h decky /trunk/kernel/arch/sparc64/src/drivers/ The FFB framebuffer looks more like 32b  
1984 6405 d 5 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller		  
1983 6406 d 9 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 6406 d 13 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.		  
1978 6407 d 5 h jermar /trunk/ sparc64 code to support physical memory that starts on non-zero addresses.
Still needs to be tested on systems with such setup.		  
1977 6408 d 2 h jermar /trunk/ Fix bad indentation in ofw.c

sparc64 work:
o Fix copyright in main.c
o Move code from unused parts of the trap table.		  
1976 6413 d 11 h jermar /trunk/kernel/arch/sparc64/ sparc64 context does not have to include the CLEANWIN register.  
1975 6417 d 4 h jermar /trunk/kernel/arch/sparc64/src/ Typo.  
1960 6428 d 5 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix the following bug:

Ticket #3 data_access_exception after killing task on sparc64
