3343 5879 d 6 h decky /branches/sparc/ add sparc branch  
3222 5921 d 6 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
2541 6206 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 6302 d 9 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2141 6389 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.
 
2075 6458 d 2 h jermar /trunk/uspace/libc/generic/ Remove left over debugging stuff.  
2071 6459 d 2 h jermar /trunk/ (c) versus (C)  
2015 6498 d 2 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.
 
1868 6593 d 8 h jermar /trunk/ sparc64 work.
- the syscall wrapper needs to use the "memory"
clobber specifier to prevent over-optimization.
- on sparc64, the user address space spans the whole
64-bit space and therefore the macro
USER_ADDRESS_SPACE_SIZE_ARCH, as it was defined,
overflows to 0
- stop using USER_ADDRESS_SPACE_SIZE_ARCH and define
MAX_HEAP_SIZE instead
- in our situation when kernel and user address spaces
are separate, the G (global) bit cannot be used
(there is no point in it anymore)
- add the DEBUG() macro to stdio.h; DEBUG() uses
SYS_IO and is a good debugging tool for getting
early userspace to work
 
1787 6649 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1719 6674 d 2 h decky /uspace/trunk/ big code cleanup, compile with -Wall -Werror to enforce better coding
there is currently one warning that requires attention, please review
 
1653 6683 d 3 h cejka /uspace/trunk/ Doxygen comments.  
1509 6688 d 8 h palkovsky /uspace/trunk/ Reworked styles in framebuffer.  
1505 6688 d 9 h palkovsky /uspace/trunk/ Added mmap, munmap calls.
Added possibility to access framebuffer using shared memory.
 
1501 6688 d 11 h palkovsky /uspace/trunk/ Allocation function for allocating free areas for mmap, map_physmem etc.  
1363 6704 d 23 h vana /uspace/trunk/ Earliest version of Userspace Framebuffer driver, with stream support in libc.
Also Virtual framebuffers made as split on main fb and its usage by streams

(please test it and report)
 
1357 6705 d 5 h jermar /uspace/trunk/libc/generic/ Cleanup after removal of as_area_accept and as_area_send.  
1330 6707 d 5 h palkovsky /uspace/trunk/ Added support to IPC for sharing pages. Remove old calls as_area_send/accept,
modify tests.
