3343 5749 d 21 h decky /branches/sparc/ add sparc branch  
3233 5772 d 22 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3145 5815 d 5 h jermar /trunk/kernel/arch/sparc64/include/ On sparc64, when the operand to the FLUSH instruction doesn't matter, the
instruction's semantics is to flush the pipeline.
 
3134 5816 d 3 h jermar /trunk/kernel/arch/ Add smc_coherence_block().  
3133 5816 d 17 h jermar /trunk/kernel/arch/ Add smc_coherence() macro to all architectures.
So far, only amd64, ia32, ia64 and sparc64 are implemented.
 
3104 5824 d 6 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3071 5826 d 23 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style
 
3070 5826 d 23 h decky /trunk/kernel/arch/ introduce portable formatting directives
remove common types
 
2860 5875 d 18 h cejka /trunk/ Context handling unified for sparc64.  
2797 5887 d 18 h jermar /trunk/kernel/ Each architecture should only announce its endianity.
The conversion macros should be defined only once.
 
2794 5888 d 18 h jermar /trunk/kernel/ Add macros for byte swapping of uint16_t's.  
2725 5944 d 23 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)
 
2721 5946 d 0 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2610 6026 d 21 h jermar /trunk/ Support for six syscall arguments for sparc64.
There is a minor stability issue which needs to be fixed (kernel panics upon entering kconsole from the
console task).
 
2510 6098 d 18 h jermar /trunk/kernel/ Experimental support for the cgsix framebuffer, which is found on old Ultra 1
worksations, and the SBUS bus and devices. Not tested.
 
2272 6237 d 19 h jermar /trunk/kernel/ Indentation and formatting fixes.  
2231 6247 d 21 h jermar /trunk/kernel/arch/sparc64/ Fix a nasty bug in the TLB miss handlers on sparc64.
After we no longer lock the kernel stack in the DTLB,
there is a real danger of nested DTLB misses. The nested
miss can very easily clobber the DTLB Tag Access register.
Therefore, the original miss may not read this register, but
it has to receive its value as an argument. The argument
value is saved in the trap table when it is guaranteed that
the nested TLB miss will not occur.
 
2216 6249 d 18 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2143 6259 d 22 h jermar /trunk/kernel/arch/sparc64/include/ Remove unneeded enum member.  
2141 6260 d 14 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.
