2141 6320 d 22 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.
 
2127 6364 d 12 h decky /trunk/kernel/generic/src/lib/ add forgotten implementation  
2126 6364 d 23 h decky /trunk/kernel/ small cleanup, more work coming  
2125 6365 d 2 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2104 6377 d 11 h decky /trunk/kernel/generic/src/lib/ more fine order of magnitude display  
2089 6379 d 8 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6390 d 1 h jermar /trunk/ (c) versus (C)  
2063 6404 d 4 h jermar /trunk/kernel/generic/src/lib/ Call big endian byte swap function instead of little endian.  
2062 6404 d 5 h jermar /trunk/kernel/generic/src/lib/ switch statement coding style fixes.  
2050 6419 d 12 h decky /trunk/kernel/ benchmarking with statistics (initial)  
2015 6429 d 1 h jermar /trunk/ Rework support for virtually indexed cache.
Instead of repeatedly flushing the data cache, which was a huge overkill, refuse to create an illegal address alias
in the kernel (again) and allocate appropriate page color in userspace instead. Extend the detection also to
SYS_PHYSMEM_MAP syscall.

Add support for tracking physical memory areas mappable by SYS_PHYSMEM_MAP.

Lots of coding style changes.
 
2005 6438 d 6 h decky /trunk/ update rd  
2002 6438 d 8 h decky /trunk/kernel/generic/ rd work  
2000 6440 d 11 h decky /trunk/kernel/ move files to more proper locations  
1896 6507 d 0 h jermar /trunk/ Convert sparc64 to detect keyboard and determine
its physical address by walking the memory representation
of the OpenFirmware device tree.

Add bus-specific functions that know how to apply the
"ranges" property to one component of the "reg" property.
Buses supported so far include FHC, EBUS and PCI.
 
1787 6580 d 3 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6587 d 5 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6601 d 9 h jermar /kernel/trunk/ Cleanup of comments.  
1708 6605 d 11 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1702 6608 d 7 h cejka /kernel/trunk/ Kernel doxygen comments updated.
