2479 6301 d 8 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2471 6307 d 2 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2445 6323 d 7 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2216 6378 d 2 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2209 6378 d 4 h decky /trunk/uspace/ use futex instead of pthread serialization
synchronize only output to stdout
cleanup
 
2188 6379 d 8 h decky /trunk/ new user space testing framework (unfinished)  
2141 6388 d 22 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.
 
2128 6432 d 3 h jermar /trunk/ Add arm32 architecture. The 32 suffix is used to specify that 16-bit Thumb
instructions are not used. The arm32 code is mostly composed of placeholders
that need to be replaced by real implementation. So far, the arm32 tree
only compiles. If run under GXEmul simulator, an infinit loop at the
kernel entry point will be entered.
 
2089 6447 d 8 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2072 6458 d 0 h jermar /trunk/uspace/libc/ Add bcmp() to libc.  
2071 6458 d 1 h jermar /trunk/ (c) versus (C)  
2015 6497 d 1 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 6499 d 23 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().
 
1999 6508 d 11 h decky /trunk/ start RAM disk support  
1992 6514 d 10 h decky /trunk/uspace/libc/include/ add bool.h  
1923 6551 d 1 h jermar /trunk/ Replace the old IRQ dispatcher and IPC notifier with new implementation.
Note that all architectures except for sparc64 are now broken
and don't even compile.
 
1868 6592 d 7 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
 
1867 6593 d 1 h jermar /trunk/uspace/ Prototype for mmap() should be in mman.h.
Anyway, is there any common sense behind naming of mman.h and mman.c?
 
1866 6593 d 1 h jermar /trunk/uspace/ Indentation and formatting facelift for libc.
Libc headers now have C99 compliant guards.
 
1863 6596 d 1 h jermar /trunk/ Allow architectures to decide between inlined and not inlined version of syscall wrapper.
Implement inlined syscall wrapper for sparc64.
 
1787 6648 d 3 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1781 6655 d 4 h jermar /uspace/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1719 6673 d 1 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
 
1707 6674 d 2 h palkovsky /uspace/trunk/ Added mouse input. Still missing support in console and framebuffer.  
1672 6680 d 23 h palkovsky /uspace/trunk/ Fast uspace scrolling using double buffering.  
1653 6682 d 2 h cejka /uspace/trunk/ Doxygen comments.  
1646 6682 d 8 h palkovsky /uspace/trunk/ Added animation to fb, fb running status shown.  
1610 6683 d 6 h palkovsky /uspace/trunk/ Revised ipc. Now it is preferrable to use only functions from async.h, they
take care of correct buffering, waiting for answers etc.
 
1596 6683 d 14 h palkovsky /uspace/trunk/ Added basic klog.
Added ipc tester.
TODO: add serializing functions to psthread, so that the lines in klog won't intermix.
 
1558 6685 d 10 h palkovsky /uspace/trunk/ Console graphics update.
Slight speed improvement on console redraw.
 
1552 6686 d 4 h palkovsky /uspace/trunk/ Added nice kernel console switching, currently works on fb devices.  
1547 6686 d 7 h palkovsky /uspace/trunk/ AS_AREA_CACHEABLE not needed anymore for sharing.
Added icons to console.
 
1532 6687 d 0 h palkovsky /uspace/trunk/ Small changes to tetris.  
1531 6687 d 2 h jermar /uspace/trunk/ Cleanup of uspace.  
1528 6687 d 2 h palkovsky /uspace/trunk/ Made tetris compile and somewhat run.
Slightly better console.
 
1523 6687 d 4 h cejka /uspace/trunk/ Console support for flush.  
1519 6687 d 5 h palkovsky /uspace/trunk/ Slowly porting tetris screen... not yet done.  
1518 6687 d 6 h palkovsky /uspace/trunk/ Changed recommended way of asynchronous communication.  
1508 6687 d 8 h vana /uspace/trunk/ Ia64 uspace keuboard uspace part  
1505 6687 d 8 h palkovsky /uspace/trunk/ Added mmap, munmap calls.
Added possibility to access framebuffer using shared memory.
