2058 6527 d 10 h jermar /trunk/kernel/arch/sparc64/src/ Improve comments.  
2049 6532 d 9 h jermar /trunk/kernel/arch/sparc64/src/ More formatting and indentation changes.  
2009 6545 d 0 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6547 d 1 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2001 6550 d 22 h jermar /trunk/kernel/ Indentation and comment fixes.  
1996 6557 d 3 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 6561 d 9 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 6562 d 1 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 6572 d 0 h jermar /trunk/kernel/arch/sparc64/src/ Typo.  
1954 6584 d 0 h jermar /trunk/ Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.		  
1917 6601 d 2 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 6611 d 3 h jermar /trunk/ Small improvements in sparc64.  
1905 6611 d 11 h jermar /trunk/kernel/arch/sparc64/src/ Small fixes.
The sparc64 kernel now compiles again even if not compiled with SMP support.		  
1903 6613 d 1 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.		  
1900 6614 d 8 h jermar /trunk/kernel/arch/sparc64/src/ Block the secondary processors after they setup kernel mapping in ITLB and DTLB and
switch to kernel trap table.		  
1899 6614 d 9 h jermar /trunk/ sparc64 work:
- Loader now starts all processors.
- Kernel halts all but the bootstrup processor for now.
- Read clock-frequency from the respective processor node in the device tree		  
1887 6626 d 8 h jermar /trunk/kernel/arch/sparc64/ When creating TLB mapping for the sparc64 kernel, enable CV (cacheable virtually) bit.
Also install locked mappings only in context 0.		  
1881 6628 d 8 h jermar /trunk/ sparc64 work:
- find a CPU node and read its clock_frequency attribute
- implement asm_delay_loop()
- set TICK_COMPARE register according to processor frequency
- small improvements at random places

OpenFirmware work:
- two new functions for walking the device tree

Generic boot loader work:
- added basic string functions

Usual pile of indentation and formatting fixes.		  
1880 6630 d 0 h jermar /trunk/ Small improvements here and there.  
1868 6635 d 7 h jermar /trunk/ sparc64 work.
- the syscall wrapper needs to use the "memory"
clobber specifier to prevent over-optimization.
- on sparc64, the user address space spans the whole
64-bit space and therefore the macro
USER_ADDRESS_SPACE_SIZE_ARCH, as it was defined,
overflows to 0
- stop using USER_ADDRESS_SPACE_SIZE_ARCH and define
MAX_HEAP_SIZE instead
- in our situation when kernel and user address spaces
are separate, the G (global) bit cannot be used
(there is no point in it anymore)
- add the DEBUG() macro to stdio.h; DEBUG() uses
SYS_IO and is a good debugging tool for getting
early userspace to work
