4685 5621 d 20 h jermar /trunk/ Fix 16bpp modes.  
4676 5624 d 22 h jermar /trunk/ RGB conversion functions should work with a well-defined pixel format.  
4669 5628 d 5 h pillai /trunk/ ARM port for development board integratorcp(ARM926EJ core module).  
4223 5744 d 2 h decky /trunk/kernel/ represent special keystrokes (cursor arrows, page up/down, delete, etc.) as appropriate Unicode characters
do not parse ANSI control sequences in kconsole, but in serial line driver
 
4187 5754 d 1 h decky /trunk/ simplify glyph mapping function
draw invalid glyphs with a distinctive color
 
4182 5754 d 3 h decky /trunk/kernel/genarch/src/fb/ fix cursor  
4177 5754 d 3 h decky /trunk/kernel/genarch/ use Unicode font glyphs and mapping for framebuffer  
4093 5766 d 0 h decky /trunk/kernel/genarch/src/ chardev_t -> outdev_t
small fixes and cleanups
 
3908 5789 d 23 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3876 5793 d 21 h decky /trunk/kernel/genarch/ add BGR 888 visual, remove FB_INVERT_ENDIAN  
3844 5805 d 20 h decky /trunk/ silent kernel console output when user space console is active  
3790 5829 d 5 h svoboda /trunk/kernel/ Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.  
3752 5841 d 6 h svoboda /trunk/kernel/genarch/src/fb/ Another memmove() instead of memcpy().  
3741 5843 d 0 h jermar /trunk/kernel/genarch/src/fb/ cstyle  
3733 5844 d 4 h decky /trunk/kernel/genarch/src/fb/ fix console overdrawing when is logo on  
3710 5851 d 20 h decky /trunk/ resurrect kernel logo  
3709 5851 d 22 h decky /trunk/kernel/ invert VGA 3:2:3 palette to reflect changes in revision 3692  
3707 5851 d 23 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)
 
3692 5857 d 20 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 5861 d 17 h rimsky /trunk/ Added forgotten stuff related to framebuffers with offsets. Got rid of VISUAL_SB1500_PALETTE.  
3672 5862 d 22 h jermar /trunk/ Merge sparc branch to trunk.  
2141 6481 d 18 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 6538 d 22 h decky /trunk/kernel/genarch/src/fb/ signed/unsigned comparison, explicit typecast  
2089 6540 d 4 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2086 6542 d 0 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 6550 d 21 h jermar /trunk/ (c) versus (C)  
2054 6578 d 19 h jermar /trunk/kernel/ Fix important comment in kernel/arch/sparc64/src/proc/scheduler.c.

Improve framebuffer code.

Formatting and indentation fixes.
 
2015 6589 d 21 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 6607 d 4 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6607 d 5 h decky /trunk/ make framebuffer code more generic  
1991 6607 d 22 h jermar /trunk/kernel/genarch/src/fb/ The prefered switch statement indentation is the one replaced by the previous commit :-)  
1990 6608 d 1 h decky /trunk/kernel/genarch/src/fb/ framebuffer cleanup  
1981 6611 d 5 h jermar /trunk/kernel/ Indentation, formatting and minor changes.  
1888 6676 d 0 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1875 6682 d 22 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 6684 d 8 h jermar /trunk/ Replace FB_BIG_ENDIAN with FB_INVERT_ENDIAN.
Omit tests for architecture endianness in deciding framebuffer endianness.
 
1869 6685 d 1 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.
 
1837 6717 d 9 h jermar /trunk/ Support 24bpp framebuffers with 4 pixelbytes (each pixel aligned on 32-bits).

At least on sparc64, the OpenFirmware linebytes property specifies the number
of pixels between consecutive scan lines of the display. Fix scanilne calculation,
including possible alignment.

Add note to 8bpp pixel functions pointing out drawbacks of that mode.
 
1790 6739 d 0 h jermar /trunk/ Remove OpenFirmware calls from kernel/ entirely.

Switch the sparc64 port to use bootinfo.

Copy memcpy from boot/ to sparc64 kernel/ and
adjust it for memcpy_from/to_uspace.
 
1787 6740 d 23 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
