3710 5628 d 21 h decky /trunk/ resurrect kernel logo  
3709 5628 d 23 h decky /trunk/kernel/ invert VGA 3:2:3 palette to reflect changes in revision 3692  
3707 5629 d 0 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)		  
3692 5634 d 21 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 5638 d 18 h rimsky /trunk/ Added forgotten stuff related to framebuffers with offsets. Got rid of VISUAL_SB1500_PALETTE.  
3672 5639 d 23 h jermar /trunk/ Merge sparc branch to trunk.  
2141 6258 d 19 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 6315 d 23 h decky /trunk/kernel/genarch/src/fb/ signed/unsigned comparison, explicit typecast  
2089 6317 d 5 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2086 6319 d 2 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 6327 d 22 h jermar /trunk/ (c) versus (C)  
2054 6355 d 21 h jermar /trunk/kernel/ Fix important comment in kernel/arch/sparc64/src/proc/scheduler.c.

Improve framebuffer code.

Formatting and indentation fixes.		  
2015 6366 d 22 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 6384 d 5 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6384 d 6 h decky /trunk/ make framebuffer code more generic  
1991 6384 d 23 h jermar /trunk/kernel/genarch/src/fb/ The prefered switch statement indentation is the one replaced by the previous commit :-)  
1990 6385 d 2 h decky /trunk/kernel/genarch/src/fb/ framebuffer cleanup  
1981 6388 d 6 h jermar /trunk/kernel/ Indentation, formatting and minor changes.  
1888 6453 d 2 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1875 6459 d 23 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.
