2479 6164 d 4 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2438 6186 d 21 h decky /trunk/ update for new compiler configuration scheme  
2250 6232 d 21 h jermar /trunk/boot/ Fix ticket #31.  
2237 6236 d 21 h jermar /trunk/boot/arch/sparc64/silo/ Upgrade SILO to 1.4.13.  
2185 6242 d 6 h decky /trunk/ rename ipcc to tester  
2160 6249 d 23 h decky /trunk/boot/arch/ remove duplicate dependency  
2141 6251 d 18 h jermar /trunk/ The Ultimate Solution To Illegal Virtual Aliases.
It is better to avoid them completely than to fight them.
Switch the sparc64 port to 16K pages. The TLBs and TSBs
continue to operate with 8K pages only. Page tables and
other generic parts operate with 16K pages.

Because the MMU doesn't support 16K directly, each 16K
page is emulated by a pair of 8K pages. With 16K pages,
illegal aliases cannot be created in 16K D-cache.		  
2082 6316 d 5 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6320 d 21 h jermar /trunk/ (c) versus (C)  
1997 6374 d 23 h decky /trunk/ add version to init and boot loader  
1989 6378 d 3 h decky /trunk/boot/arch/sparc64/loader/ remove disasm on clean  
1982 6381 d 5 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.		  
1979 6381 d 21 h jermar /trunk/ Configuration changes on sparc64.
Compile TSB support by default.
Ask whether to start AP processors in the loader.		  
1978 6381 d 22 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 6382 d 18 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.		  
1972 6394 d 4 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.		  
1917 6420 d 23 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 6431 d 0 h jermar /trunk/ Small improvements in sparc64.  
1903 6432 d 22 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.		  
1899 6434 d 5 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
