3343 5926 d 6 h decky /branches/sparc/ add sparc branch  
3222 5968 d 7 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
2541 6253 d 11 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 6349 d 10 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2141 6437 d 0 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 6505 d 2 h jermar /trunk/uspace/libc/generic/ Remove left over debugging stuff.  
2071 6506 d 3 h jermar /trunk/ (c) versus (C)  
2015 6545 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.
 
1868 6640 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 6696 d 5 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1719 6721 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 6730 d 4 h cejka /uspace/trunk/ Doxygen comments.  
1509 6735 d 9 h palkovsky /uspace/trunk/ Reworked styles in framebuffer.  
1505 6735 d 10 h palkovsky /uspace/trunk/ Added mmap, munmap calls.
Added possibility to access framebuffer using shared memory.
 
1501 6735 d 12 h palkovsky /uspace/trunk/ Allocation function for allocating free areas for mmap, map_physmem etc.  
1363 6752 d 0 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 6752 d 6 h jermar /uspace/trunk/libc/generic/ Cleanup after removal of as_area_accept and as_area_send.  
1330 6754 d 6 h palkovsky /uspace/trunk/ Added support to IPC for sharing pages. Remove old calls as_area_send/accept,
modify tests.
 
1307 6757 d 7 h jermar /uspace/trunk/ SYS_AS_AREA_DESTROY support for uspace.

Formatting fixes in libpci.
 
1250 6770 d 10 h jermar /uspace/trunk/ Add as.h to libc and compile pci module only for amd64 and ia32.
