3707 5616 d 10 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)		  
3692 5622 d 8 h rimsky /trunk/ Fixed the bug when on SunBlade1500 we wrote to an address outside the framebuffer memory. A nasty hack to the 8-bit palette so that on sb1500 we do not have to turn black into white and white into black.  
3679 5626 d 5 h rimsky /trunk/ Added forgotten stuff related to framebuffers with offsets. Got rid of VISUAL_SB1500_PALETTE.  
3672 5627 d 9 h jermar /trunk/ Merge sparc branch to trunk.  
2141 6246 d 6 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.		  
2102 6303 d 10 h decky /trunk/kernel/genarch/src/fb/ signed/unsigned comparison, explicit typecast  
2089 6304 d 16 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2086 6306 d 12 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 6315 d 9 h jermar /trunk/ (c) versus (C)  
2054 6343 d 7 h jermar /trunk/kernel/ Fix important comment in kernel/arch/sparc64/src/proc/scheduler.c.

Improve framebuffer code.

Formatting and indentation fixes.		  
2015 6354 d 9 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.		  
1994 6371 d 16 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6371 d 17 h decky /trunk/ make framebuffer code more generic  
1991 6372 d 10 h jermar /trunk/kernel/genarch/src/fb/ The prefered switch statement indentation is the one replaced by the previous commit :-)  
1990 6372 d 13 h decky /trunk/kernel/genarch/src/fb/ framebuffer cleanup  
1981 6375 d 17 h jermar /trunk/kernel/ Indentation, formatting and minor changes.  
1888 6440 d 12 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1875 6447 d 9 h jermar /trunk/ sparc64 work.
- Changes to enable userspace keyboard drivers.
- Fix z8530 initialization (i.e. clear any pending Tx interrupts).
- Experimental support for framebuffers with inverted colors.		  
1871 6448 d 20 h jermar /trunk/ Replace FB_BIG_ENDIAN with FB_INVERT_ENDIAN.
Omit tests for architecture endianness in deciding framebuffer endianness.		  
1869 6449 d 12 h jermar /trunk/ Pass "fb.bpp-align" property to userspace so that our fb task works properly even on
framebuffers used in some Sun hardware.
