3745 5799 d 16 h rimsky /branches/sparc/ Merged latest trunk changes (revs 3722 to 3744) into the sparc branch.  
3742 5799 d 18 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3343 5928 d 13 h decky /branches/sparc/ add sparc branch  
2677 6160 d 14 h jermar /trunk/ Rename IPC_M_AS_AREA_SEND to IPC_M_SHARE_OUT. Rename IPC_M_AS_AREA_RECV to
IPC_M_SHARE_IN. Provide user-friendly wrappers for these methods so that even
dummies can get it right. Some applications using simpler protocols still use
these methods directly.		  
2619 6201 d 9 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().		  
2479 6351 d 17 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2301 6401 d 16 h decky /trunk/uspace/fb/ copy proper portion of viewport on screen border
(fixes ticket #34)		  
2141 6439 d 7 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 6508 d 10 h jermar /trunk/ (c) versus (C)  
2070 6508 d 17 h jermar /trunk/ Rather big indentation and formatting changes.
More inteligent long line wrapping.		  
2025 6545 d 7 h jermar /trunk/ Coding style fixes.  
2015 6547 d 10 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 6550 d 8 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 6564 d 17 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6564 d 18 h decky /trunk/ make framebuffer code more generic  
1954 6591 d 9 h jermar /trunk/ Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.		  
1888 6633 d 13 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1886 6633 d 17 h jermar /trunk/uspace/fb/ Mapping framebuffer as cacheable was identified to cause the sparc64 port not work on Sun Ultra 5.  
1875 6640 d 10 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 6641 d 21 h jermar /trunk/ Replace FB_BIG_ENDIAN with FB_INVERT_ENDIAN.
Omit tests for architecture endianness in deciding framebuffer endianness.
