2619 6022 d 1 h jermar /trunk/ Modify ipc_answer_*() to make use of all six syscall arguments. The recommended
means of answering calls is via the ipc_answer_m() macros (where m denotes the
number of return arguments) that automatically decide between the fast register
version or the slow universal version of ipc_answer().		  
2541 6076 d 10 h jermar /trunk/uspace/ Header cleanup.
Move off_t, size_t and ssize_t into sys/types.h.
Get rid off the non-standard and dummy types.h.		  
2479 6172 d 9 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2476 6175 d 2 h jermar /trunk/ Cleanup.  
2301 6222 d 9 h decky /trunk/uspace/fb/ copy proper portion of viewport on screen border
(fixes ticket #34)		  
2141 6259 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.		  
2071 6329 d 2 h jermar /trunk/ (c) versus (C)  
2070 6329 d 10 h jermar /trunk/ Rather big indentation and formatting changes.
More inteligent long line wrapping.		  
2025 6366 d 0 h jermar /trunk/ Coding style fixes.  
2015 6368 d 3 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.		  
2012 6371 d 0 h jermar /trunk/ Eliminate confusion between SYS_MAP_PHYSMEM and sys_physmem_map.
The syscall is to be called SYS_PHYSMEM_MAP from now on and the functions that participate in its implementation are
called *physmem_map().		  
1994 6385 d 9 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6385 d 10 h decky /trunk/ make framebuffer code more generic  
1954 6412 d 1 h jermar /trunk/ Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.		  
1888 6454 d 6 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1886 6454 d 10 h jermar /trunk/uspace/fb/ Mapping framebuffer as cacheable was identified to cause the sparc64 port not work on Sun Ultra 5.  
1875 6461 d 3 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 6462 d 14 h jermar /trunk/ Replace FB_BIG_ENDIAN with FB_INVERT_ENDIAN.
Omit tests for architecture endianness in deciding framebuffer endianness.		  
1869 6463 d 6 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.		  
1787 6519 d 5 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
