2488 6212 d 2 h jermar /trunk/uspace/lib/libc/generic/ Improve comments in async.c  
2486 6212 d 6 h jermar /trunk/uspace/lib/libc/ Remove duplicit and empty time.h from libc.
Move timeval functions from async.c to time.c.
 
2485 6216 d 4 h jermar /trunk/uspace/lib/libc/generic/ More fibril/psthread cleanup.  
2484 6216 d 5 h jermar /trunk/uspace/lib/libc/generic/ More psthread/fibril cleanup.  
2483 6216 d 8 h jermar /trunk/uspace/lib/libc/ Remove fibril_join().
We cannot guarantee our assumptions that easily.
This broken feature is removed instead of fixing because there are now users of it.
 
2482 6216 d 23 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.
 
2481 6217 d 1 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 6221 d 11 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2471 6227 d 5 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2470 6231 d 3 h jermar /trunk/ Fix a double-free recently introduced in revision r2436.
Add a comment clarifying the life-cycle of the kernel_uarg structure.

Comment out the freeing of userspace thread stack while still running on it.
This should be fixed by implementing userspace version of thread_join().
 
2469 6231 d 4 h jermar /trunk/uspace/libc/generic/ Fix a bug in userspace thread_create() that confused success of the
syscall with failure.
 
2468 6231 d 6 h jermar /trunk/ Remove some forgotten \r from arm32 files.
Formatting changes.
Add some correct BOOT_mips32_* guards.
 
2465 6236 d 9 h jermar /trunk/ Merge arm32 into trunk.  
2445 6243 d 10 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2438 6244 d 3 h decky /trunk/ update for new compiler configuration scheme  
2436 6245 d 4 h jermar /trunk/ Fix two memory leaks.

In kernel, kernel_uarg structure needs to be deallocated when a thread
with userspace context is destroyed.

In userspace, the return value of the SYS_THREAD_CREATE must be checked
for error conditions and in case of error, uarg and stack must be freed
up.
 
2359 6257 d 14 h jermar /trunk/ Improve comments for the IPC subsystem.
Fix formatting and indentation.
 
2230 6296 d 8 h jermar /trunk/uspace/ Remove printf() serialization from thread1 test in tester.
The agreement among developers seems to be that:
- there _must_ be a futex to serialize access to printf()
- there _must_ be pseudo thread serialization in printf()
- the best place for this is vprintf(), the one that goes to console
 
2229 6296 d 10 h jermar /trunk/ Revert some of the changes introduced in revision 2209.
I think it is not correct to remove serialization of pseudo threads in printf_core.c.
With thread-level futex serialization, several pseudo threads running in one thread could easily deadlock
the task.

Add a dedicated futex serialization to thread1.c test only.
 
2216 6298 d 4 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2209 6298 d 6 h decky /trunk/uspace/ use futex instead of pthread serialization
synchronize only output to stdout
cleanup
 
2192 6299 d 10 h decky /trunk/uspace/libc/arch/sparc64/include/ fix uspace atomic_add according kernel code  
2188 6299 d 10 h decky /trunk/ new user space testing framework (unfinished)  
2141 6309 d 1 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 6352 d 5 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 6367 d 11 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2082 6373 d 11 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2075 6377 d 3 h jermar /trunk/uspace/libc/generic/ Remove left over debugging stuff.  
2072 6378 d 3 h jermar /trunk/uspace/libc/ Add bcmp() to libc.  
2071 6378 d 4 h jermar /trunk/ (c) versus (C)  
2070 6378 d 11 h jermar /trunk/ Rather big indentation and formatting changes.
More inteligent long line wrapping.
 
2061 6396 d 11 h jermar /trunk/ Improve comments and fix formatting in (sparc64) TLS implementation.
Improve some comments and formatting in sparc64 uspace thread library
code.

Update required msim version.
 
2025 6415 d 1 h jermar /trunk/ Coding style fixes.  
2015 6417 d 4 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 6420 d 2 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().
 
2005 6426 d 9 h decky /trunk/ update rd  
1999 6428 d 13 h decky /trunk/ start RAM disk support  
1992 6434 d 13 h decky /trunk/uspace/libc/include/ add bool.h  
1971 6457 d 2 h jermar /trunk/uspace/libc/generic/ Textual changes.  
1923 6471 d 3 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.
