2522 6090 d 23 h jermar /trunk/uspace/lib/libc/ Add wrappers facilitating easy use of IPC_M_DATA_SEND calls and answers.  
2495 6155 d 14 h jermar /trunk/uspace/lib/libc/generic/io/ Formatting changes.  
2492 6161 d 12 h jermar /trunk/uspace/lib/libc/generic/ Add comment clarifying how a fibril waiting for a message gets rescheduled.  
2490 6163 d 13 h jermar /trunk/uspace/lib/libc/generic/ Improve comments in async.c  
2488 6165 d 8 h jermar /trunk/uspace/lib/libc/generic/ Improve comments in async.c  
2486 6165 d 11 h jermar /trunk/uspace/lib/libc/ Remove duplicit and empty time.h from libc.
Move timeval functions from async.c to time.c.		  
2485 6169 d 9 h jermar /trunk/uspace/lib/libc/generic/ More fibril/psthread cleanup.  
2484 6169 d 10 h jermar /trunk/uspace/lib/libc/generic/ More psthread/fibril cleanup.  
2483 6169 d 14 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 6170 d 5 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.		  
2481 6170 d 7 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 6174 d 16 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2471 6180 d 10 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)		  
2470 6184 d 8 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 6184 d 10 h jermar /trunk/uspace/libc/generic/ Fix a bug in userspace thread_create() that confused success of the
syscall with failure.		  
2445 6196 d 16 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)		  
2436 6198 d 10 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 6210 d 19 h jermar /trunk/ Improve comments for the IPC subsystem.
Fix formatting and indentation.		  
2230 6249 d 13 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 6249 d 16 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.
