2068 6429 d 7 h jermar /trunk/kernel/ Formatting and indentation fixes.  
2067 6432 d 5 h jermar /trunk/kernel/ More formatting changes.  
2065 6435 d 22 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
2058 6448 d 9 h jermar /trunk/kernel/arch/sparc64/src/ Improve comments.  
2056 6449 d 11 h jermar /trunk/kernel/arch/sparc64/include/ Fix mismatched byteswapping macros on sparc64.  
2055 6449 d 12 h jermar /trunk/kernel/arch/sparc64/src/ sparc64 work:
- No need to lock kernel stack and userspace window buffer into DTLB.		  
2054 6449 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 6453 d 8 h jermar /trunk/kernel/arch/sparc64/src/ More formatting and indentation changes.  
2048 6454 d 1 h jermar /trunk/ Formatting and indentation changes.  
2047 6455 d 23 h jermar /trunk/kernel/arch/sparc64/include/ Convert sparc64 critical section barriers to RMO memory model.
More portable, no confusion from documentation.		  
2046 6456 d 1 h jermar /trunk/kernel/arch/sparc64/include/ Another comment fix.  
2045 6456 d 1 h jermar /trunk/kernel/arch/sparc64/include/ Fix comment.  
2044 6456 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 6456 d 2 h jermar /trunk/kernel/arch/sparc64/src/ Make the sparc64 kernel compile again.  
2038 6456 d 21 h jermar /trunk/kernel/arch/sparc64/ Remove old stuff.  
2037 6456 d 22 h jermar /trunk/kernel/arch/sparc64/include/ Backout change from revision 2034.
sparc64 is not yet ready for get_cycle().		  
2034 6457 d 6 h jermar /trunk/kernel/arch/sparc64/include/ get_cycle() for sparc64.  
2025 6458 d 21 h jermar /trunk/ Coding style fixes.  
2023 6459 d 0 h decky /trunk/kernel/arch/ add dummy cycle.h  
2016 6459 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 6461 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 6465 d 23 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix comment.  
2009 6465 d 23 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6468 d 0 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2007 6468 d 22 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 6470 d 4 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
2001 6471 d 21 h jermar /trunk/kernel/ Indentation and comment fixes.  
1996 6478 d 1 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 6478 d 6 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6478 d 7 h decky /trunk/ make framebuffer code more generic  
1988 6479 d 22 h jermar /trunk/kernel/arch/sparc64/src/mm/ Update comment and move initialization code away from application processor codepath.  
1987 6480 d 1 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 6480 d 4 h decky /trunk/kernel/arch/sparc64/src/drivers/ The FFB framebuffer looks more like 32b  
1984 6481 d 0 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller		  
1983 6482 d 4 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 6482 d 7 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 6483 d 0 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 6483 d 20 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 6489 d 5 h jermar /trunk/kernel/arch/sparc64/ sparc64 context does not have to include the CLEANWIN register.  
1975 6492 d 22 h jermar /trunk/kernel/arch/sparc64/src/ Typo.
