2489 6256 d 11 h jermar /trunk/ Allow HelenOS to be built by a native gcc on Solaris.  
2488 6258 d 4 h jermar /trunk/uspace/lib/libc/generic/ Improve comments in async.c  
2486 6258 d 7 h jermar /trunk/uspace/lib/libc/ Remove duplicit and empty time.h from libc.
Move timeval functions from async.c to time.c.		  
2485 6262 d 5 h jermar /trunk/uspace/lib/libc/generic/ More fibril/psthread cleanup.  
2484 6262 d 6 h jermar /trunk/uspace/lib/libc/generic/ More psthread/fibril cleanup.  
2483 6262 d 10 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 6263 d 1 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.		  
2481 6263 d 3 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 6267 d 12 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2471 6273 d 6 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)		  
2470 6277 d 4 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 6277 d 6 h jermar /trunk/uspace/libc/generic/ Fix a bug in userspace thread_create() that confused success of the
syscall with failure.		  
2468 6277 d 7 h jermar /trunk/ Remove some forgotten \r from arm32 files.
Formatting changes.
Add some correct BOOT_mips32_* guards.		  
2465 6282 d 11 h jermar /trunk/ Merge arm32 into trunk.  
2445 6289 d 12 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)		  
2438 6290 d 5 h decky /trunk/ update for new compiler configuration scheme  
2436 6291 d 6 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 6303 d 15 h jermar /trunk/ Improve comments for the IPC subsystem.
Fix formatting and indentation.		  
2230 6342 d 10 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 6342 d 12 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.
