2160 6255 d 7 h decky /trunk/boot/arch/ remove duplicate dependency  
2141 6257 d 3 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.		  
2128 6300 d 7 h jermar /trunk/ Add arm32 architecture. The 32 suffix is used to specify that 16-bit Thumb
instructions are not used. The arm32 code is mostly composed of placeholders
that need to be replaced by real implementation. So far, the arm32 tree
only compiles. If run under GXEmul simulator, an infinit loop at the
kernel entry point will be entered.		  
2082 6321 d 14 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6326 d 6 h jermar /trunk/ (c) versus (C)  
2014 6367 d 8 h decky /trunk/ version bump to Xen 3.0.3 (not fully operational yet)  
2013 6367 d 8 h decky /trunk/boot/arch/ bump to GRUB version 0.97  
1998 6380 d 7 h decky /trunk/boot/arch/ add version tag to other bootloaders  
1997 6380 d 7 h decky /trunk/ add version to init and boot loader  
1989 6383 d 12 h decky /trunk/boot/arch/sparc64/loader/ remove disasm on clean  
1982 6386 d 14 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 6387 d 5 h jermar /trunk/ Configuration changes on sparc64.
Compile TSB support by default.
Ask whether to start AP processors in the loader.		  
1978 6387 d 6 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 6388 d 3 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 6399 d 13 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.		  
1952 6413 d 8 h jermar /trunk/ Rename xen32 to ia32xen.
The name seems to be more logical as Xen supports more host architectures.		  
1917 6426 d 7 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 6436 d 9 h jermar /trunk/ Small improvements in sparc64.  
1903 6438 d 7 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 6439 d 14 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
