2141 6271 d 23 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.
 
2125 6316 d 3 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2106 6324 d 9 h jermar /trunk/kernel/ Merge as_t structure into one and leave the differring parts in as_genarch_t.

Indentation and formatting changes in header files.
 
2102 6329 d 3 h decky /trunk/kernel/genarch/src/fb/ signed/unsigned comparison, explicit typecast  
2101 6329 d 3 h decky /trunk/kernel/ fix signed/unsigned comparison and integer overflow  
2100 6329 d 4 h decky /trunk/kernel/ signed/unsigned comparison, explicit typecast  
2089 6330 d 9 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2086 6332 d 6 h jermar /trunk/kernel/genarch/src/fb/ Don't write to frame buffer memory, which is past the resolution.
This fixes Ticket #17

Coding style a formatting changes in the frame buffer code.
 
2071 6341 d 2 h jermar /trunk/ (c) versus (C)  
2054 6369 d 1 h jermar /trunk/kernel/ Fix important comment in kernel/arch/sparc64/src/proc/scheduler.c.

Improve framebuffer code.

Formatting and indentation fixes.
 
2015 6380 d 2 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.
 
2007 6388 d 1 h jermar /trunk/kernel/ Introduce page colors. So far, only sparc64 uses correct page color bits. Other architectures have a dummy define
specifying zero bits for a page color.

There is a new check of page color in as_area_share(). Because of lack of support for this in the userspace, the
check has been #ifef'ed out.
 
1994 6397 d 9 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6397 d 10 h decky /trunk/ make framebuffer code more generic  
1991 6398 d 3 h jermar /trunk/kernel/genarch/src/fb/ The prefered switch statement indentation is the one replaced by the previous commit :-)  
1990 6398 d 6 h decky /trunk/kernel/genarch/src/fb/ framebuffer cleanup  
1981 6401 d 10 h jermar /trunk/kernel/ Indentation, formatting and minor changes.  
1974 6412 d 4 h jermar /trunk/kernel/genarch/src/ofw/ Rewrite OFW device tree traversal algorithms to iterate over the list of peers rather than recurse on each
peer node. This saves us from big troubles with stack overflows.
 
1972 6414 d 9 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.
 
1957 6423 d 10 h decky /trunk/kernel/ ia32: mouse support, mouse regrab is still broken
