2482 6209 d 22 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.
 
2481 6209 d 23 h jermar /trunk/uspace/lib/libc/ 1. Implement simple joining of pseudo threads. Only one pseudo thread is allowed to join another pseudo
thread. The restriction is that both pseudo threads must be from the same thread (this is to simplify
synchronization). The joiner doesn't free anything from the joinee. It only gets its return value. Not
tested thoroughly yet.

2. Cleanup of a dead pseudo thread is done by the next scheduled pseudo thread. Not tested thoroughly yet.
 
2479 6214 d 9 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2471 6220 d 3 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2445 6236 d 8 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2216 6291 d 3 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2209 6291 d 5 h decky /trunk/uspace/ use futex instead of pthread serialization
synchronize only output to stdout
cleanup
 
2188 6292 d 9 h decky /trunk/ new user space testing framework (unfinished)  
2141 6301 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.
 
2128 6345 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 6360 d 9 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2072 6371 d 1 h jermar /trunk/uspace/libc/ Add bcmp() to libc.  
2071 6371 d 2 h jermar /trunk/ (c) versus (C)  
2015 6410 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.
 
2012 6413 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().
 
1999 6421 d 12 h decky /trunk/ start RAM disk support  
1992 6427 d 11 h decky /trunk/uspace/libc/include/ add bool.h  
1923 6464 d 2 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 6505 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
 
1867 6506 d 2 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 6506 d 2 h jermar /trunk/uspace/ Indentation and formatting facelift for libc.
Libc headers now have C99 compliant guards.
 
1863 6509 d 2 h jermar /trunk/ Allow architectures to decide between inlined and not inlined version of syscall wrapper.
Implement inlined syscall wrapper for sparc64.
 
1787 6561 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1781 6568 d 5 h jermar /uspace/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1719 6586 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
 
1707 6587 d 3 h palkovsky /uspace/trunk/ Added mouse input. Still missing support in console and framebuffer.  
1672 6594 d 0 h palkovsky /uspace/trunk/ Fast uspace scrolling using double buffering.  
1653 6595 d 3 h cejka /uspace/trunk/ Doxygen comments.  
1646 6595 d 8 h palkovsky /uspace/trunk/ Added animation to fb, fb running status shown.  
1610 6596 d 7 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 6596 d 15 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 6598 d 11 h palkovsky /uspace/trunk/ Console graphics update.
Slight speed improvement on console redraw.
 
1552 6599 d 5 h palkovsky /uspace/trunk/ Added nice kernel console switching, currently works on fb devices.  
1547 6599 d 8 h palkovsky /uspace/trunk/ AS_AREA_CACHEABLE not needed anymore for sharing.
Added icons to console.
 
1532 6600 d 1 h palkovsky /uspace/trunk/ Small changes to tetris.  
1531 6600 d 3 h jermar /uspace/trunk/ Cleanup of uspace.  
1528 6600 d 3 h palkovsky /uspace/trunk/ Made tetris compile and somewhat run.
Slightly better console.
 
1523 6600 d 5 h cejka /uspace/trunk/ Console support for flush.  
1519 6600 d 6 h palkovsky /uspace/trunk/ Slowly porting tetris screen... not yet done.  
1518 6600 d 7 h palkovsky /uspace/trunk/ Changed recommended way of asynchronous communication.
