4647 5592 d 21 h jermar /branches/arm/ Branch out a new arm branch.  
4314 5677 d 19 h jermar /trunk/kernel/arch/sparc64/ Replace all deprecated BA (Bicc) instructions with BA %xcc instructions.  
4277 5684 d 23 h jermar /trunk/kernel/arch/sparc64/ On sparc64, do fast indentity mapping only for physical memory.
For addresses above physical memory, such as I/O devices,
fall through to the C miss handler and map the memory noncacheably.
Replace deprecated Bicc instructions with proper Bcc instructions.		  
3672 5814 d 19 h jermar /trunk/ Merge sparc branch to trunk.  
2078 6498 d 22 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.		  
2071 6502 d 19 h jermar /trunk/ (c) versus (C)  
2058 6529 d 4 h jermar /trunk/kernel/arch/sparc64/src/ Improve comments.  
2049 6534 d 3 h jermar /trunk/kernel/arch/sparc64/src/ More formatting and indentation changes.  
2009 6546 d 18 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6548 d 19 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2001 6552 d 16 h jermar /trunk/kernel/ Indentation and comment fixes.  
1996 6558 d 21 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.		  
1982 6563 d 2 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 6563 d 19 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.		  
1975 6573 d 17 h jermar /trunk/kernel/arch/sparc64/src/ Typo.  
1954 6585 d 18 h jermar /trunk/ Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.		  
1917 6602 d 20 h jermar /trunk/ sparc64 work:
- hw_map() can now support up to 8M requests
- CPU stacks are now locked in DTLB of the respective processor
- kernel in the boot phase no longer relies on the stack provided by OpenFirmware
- instead of of doing FLUSHW during kernel startup, simply set the
window state registers to the wanted state
- NWINDOW -> NWINDOWS
- Add/fix some comments and copyrights.		  
1906 6612 d 21 h jermar /trunk/ Small improvements in sparc64.  
1905 6613 d 5 h jermar /trunk/kernel/arch/sparc64/src/ Small fixes.
The sparc64 kernel now compiles again even if not compiled with SMP support.		  
1903 6614 d 19 h jermar /trunk/ SMP stuff for sparc64.
Almost complete except for IPIs.
The absence of IPI support deadlocks
the kernel when more CPUs are configured.
