2492 6229 d 17 h jermar /trunk/uspace/lib/libc/generic/ Add comment clarifying how a fibril waiting for a message gets rescheduled.  
2491 6229 d 18 h jermar /trunk/uspace/ Fix two minor bugs in uspace's make clean.  
2490 6231 d 17 h jermar /trunk/uspace/lib/libc/generic/ Improve comments in async.c  
2489 6231 d 20 h jermar /trunk/ Allow HelenOS to be built by a native gcc on Solaris.  
2488 6233 d 12 h jermar /trunk/uspace/lib/libc/generic/ Improve comments in async.c  
2486 6233 d 16 h jermar /trunk/uspace/lib/libc/ Remove duplicit and empty time.h from libc.
Move timeval functions from async.c to time.c.
 
2485 6237 d 14 h jermar /trunk/uspace/lib/libc/generic/ More fibril/psthread cleanup.  
2484 6237 d 15 h jermar /trunk/uspace/lib/libc/generic/ More psthread/fibril cleanup.  
2483 6237 d 19 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 6238 d 10 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.
 
2481 6238 d 11 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.
 
2480 6242 d 21 h jermar /trunk/uspace/ Remove dummy presenter.  
2479 6242 d 21 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2478 6244 d 17 h jermar /trunk/uspace/rd/ Add sanity checks for reads and writes that occur past the end of the
ramdisk image.
 
2476 6245 d 14 h jermar /trunk/ Cleanup.  
2475 6245 d 14 h jermar /trunk/uspace/rd/ Improve the rd task (not tested):
- allow more connections
- support write operation
- support concurrent requests
- sanity checks
- add comments

Please review.
 
2471 6248 d 15 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2470 6252 d 13 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 6252 d 14 h jermar /trunk/uspace/libc/generic/ Fix a bug in userspace thread_create() that confused success of the
syscall with failure.
 
2468 6252 d 16 h jermar /trunk/ Remove some forgotten \r from arm32 files.
Formatting changes.
Add some correct BOOT_mips32_* guards.
 
2465 6257 d 19 h jermar /trunk/ Merge arm32 into trunk.  
2449 6264 d 2 h decky /trunk/uspace/rd/ remove unnecessary includes  
2445 6264 d 20 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2443 6265 d 12 h jermar /trunk/ sscc -> suncc  
2442 6265 d 12 h jermar /trunk/ Add dummy option for Sun Studio C Compiler.
For each architecture, offer only compilers that support the target.
 
2438 6265 d 13 h decky /trunk/ update for new compiler configuration scheme  
2436 6266 d 15 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 6279 d 0 h jermar /trunk/ Improve comments for the IPC subsystem.
Fix formatting and indentation.
 
2321 6286 d 19 h decky /trunk/ keep mouse state in i8042_grab, unify keyboard and mouse IRQ handler
(this fixes ticket #12)
 
2301 6292 d 20 h decky /trunk/uspace/fb/ copy proper portion of viewport on screen border
(fixes ticket #34)
 
2230 6317 d 18 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 6317 d 21 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 6319 d 14 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2210 6319 d 16 h decky /trunk/ use more useful values  
2209 6319 d 17 h decky /trunk/uspace/ use futex instead of pthread serialization
synchronize only output to stdout
cleanup
 
2193 6320 d 20 h decky /trunk/uspace/tester/ reimplement all tests from original ipcc
(cleanup needed)
 
2192 6320 d 20 h decky /trunk/uspace/libc/arch/sparc64/include/ fix uspace atomic_add according kernel code  
2188 6320 d 21 h decky /trunk/ new user space testing framework (unfinished)  
2186 6320 d 22 h decky /trunk/uspace/tester/ rename ipcc.c to tester.c  
2185 6320 d 22 h decky /trunk/ rename ipcc to tester
