3398 5725 d 10 h rimsky /branches/sparc/ US used as a code for the UltraSPARC I-II subarchitecture instead of US2.  
3365 5743 d 2 h rimsky /branches/sparc/ Integrated US-III port into the build process; added script for downloading and patching SILO; added patched SILO binaries; modified sources of the Sparc64 port up to the beginning of the main_bsp_separated_stack function: phys. address size not hardwired but configurable (41 bits on US-II, 43 bits on US-III), WSTATE register implicitly written 0 on startup.  
3343 5749 d 7 h decky /branches/sparc/ add sparc branch  
2078 6325 d 8 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 6329 d 4 h jermar /trunk/ (c) versus (C)  
2058 6355 d 13 h jermar /trunk/kernel/arch/sparc64/src/ Improve comments.  
2049 6360 d 12 h jermar /trunk/kernel/arch/sparc64/src/ More formatting and indentation changes.  
2009 6373 d 3 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6375 d 4 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2001 6379 d 1 h jermar /trunk/kernel/ Indentation and comment fixes.  
1996 6385 d 6 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 6389 d 12 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 6390 d 4 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 6400 d 2 h jermar /trunk/kernel/arch/sparc64/src/ Typo.  
1954 6412 d 3 h jermar /trunk/ Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.		  
1917 6429 d 5 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 6439 d 6 h jermar /trunk/ Small improvements in sparc64.  
1905 6439 d 14 h jermar /trunk/kernel/arch/sparc64/src/ Small fixes.
The sparc64 kernel now compiles again even if not compiled with SMP support.		  
1903 6441 d 4 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 6442 d 11 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.
