2482 6195 d 7 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.
 
2481 6195 d 9 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 6199 d 19 h jermar /trunk/uspace/ Remove dummy presenter.  
2479 6199 d 19 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2478 6201 d 15 h jermar /trunk/uspace/rd/ Add sanity checks for reads and writes that occur past the end of the
ramdisk image.
 
2477 6202 d 9 h kebrt /trunk/kernel/arch/arm32/src/ fixes bug causing crash in tester 'thread1' test  
2476 6202 d 11 h jermar /trunk/ Cleanup.  
2475 6202 d 11 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.
 
2474 6204 d 10 h jermar /tags/0.2.0.5/ Add tag for HelenOS 0.2.0.5.  
2473 6204 d 11 h jermar /trunk/ Bump version to 0.2.0.5 (Twilight).  
2472 6205 d 13 h jermar /trunk/kernel/generic/src/ipc/ Some left-over stuff from the last commit (IPC cleanup and improved
comments.)
 
2471 6205 d 13 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2470 6209 d 11 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 6209 d 12 h jermar /trunk/uspace/libc/generic/ Fix a bug in userspace thread_create() that confused success of the
syscall with failure.
 
2468 6209 d 14 h jermar /trunk/ Remove some forgotten \r from arm32 files.
Formatting changes.
Add some correct BOOT_mips32_* guards.
 
2467 6209 d 15 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2466 6213 d 18 h mencl /branches/rcu/kernel/ Added forgoten favl.h and favl.c and changed balance atribute of avl
tree to int8_t.
 
2465 6214 d 17 h jermar /trunk/ Merge arm32 into trunk.  
2464 6215 d 12 h jermar /branches/arm/kernel/ Cleanup of arm32 branch.
- indentation and formatting
- replacement of \n\r with mere \n
- added -DFB_INVERT_ENDIAN so that the framebuffer has correct colors
 
2463 6215 d 23 h hudecek /branches/rcu/kernel/genarch/src/kbd/ Fixed a typo  
2462 6216 d 12 h jermar /trunk/kernel/ Replace gcc-specific __FUNCTION__ with C99 __func__.
suncc's xregs=no%float can be used only on sparc64.
 
2461 6216 d 12 h mencl /branches/rcu/kernel/ Added Fast avl tree structure which should be used as timeout data structure instead of simple avl tree. This
structure has much faster search min and delete min operations (constant time).
 
2460 6216 d 12 h jermar /trunk/kernel/ Better infrastructure for building with different compilers.
Separate ICC_CFLAGS added, SUNCC_CFLAGS extended.
 
2459 6216 d 15 h jermar /trunk/kernel/arch/ Fix a bug in ia32 and ia32xen Sun Studio builds.
In arch Makefile.inc, SUNCC_CFLAGS can only be appended via the += operator.
 
2458 6216 d 16 h jermar /trunk/kernel/arch/mips32/ Fix mips32 build script.
Replace CFLAGS with GCC_CFLAGS.
 
2457 6216 d 16 h jermar /trunk/kernel/arch/ia32xen/src/smp/ Fix ia32xen so that it can be built.  
2456 6217 d 11 h hudecek /branches/rcu/kernel/ Model use of RCU  
2455 6217 d 11 h jermar /trunk/kernel/ Some non-C files (e.g. .S and linker scripts) must be still "compiled" with gcc and GCC_CFLAGS.  
2454 6217 d 11 h jermar /trunk/kernel/ A bit of infrastructure for building with different compilers.
CFLAGS split into GCC_CFLAGS and SUNCC_CFLAGS.
As of now, there are no separate ICC_CFLAGS, but can be easily added.
 
2453 6217 d 17 h jermar /trunk/kernel/ More suncc fixes.
- remove more empty declarations
- add options to turn errors on empty structs into warnings and options to
silence these warnings
 
2452 6217 d 18 h jermar /trunk/kernel/ More suncc fixes.
- Removed extra semicolons after function declaration.
- Sun Studio recognizes only C99 __func__ and no gcc-specific __FUNCTION__.
In this case, a simple -D option can fix the problem.
 
2451 6218 d 13 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2450 6219 d 14 h mencl /branches/rcu/kernel/ Repaired avl and extavl tree timeout unregister and delete_min. These
faults caused problems with initializing cpus and they appeared only in
multi processor systems.
 
2449 6220 d 23 h decky /trunk/uspace/rd/ remove unnecessary includes  
2448 6221 d 15 h jermar /branches/arm/kernel/arch/arm32/src/cpu/ Start the CPU identification string with cpu[0-9].  
2447 6221 d 17 h jermar /trunk/kernel/generic/src/main/ Split accidently joined lines.  
2446 6221 d 17 h jermar /trunk/kernel/generic/ More efficient and simpler task termination.

Based on the assumption, that after its creation, only the task itself can create more threads for itself,
the last thread with userspace context to execute thread_exit() will perform futex and IPC cleanup. When
the task has no threads, it is destroyed. Both the cleanup and destruction is controlled by reference
counting.

As for userspace threads, even though there could be a global garbage collector for joining threads, it is
much simpler if the uinit thread detaches itself before switching to userspace.

task_kill() is now an idempotent operation. It just instructs the threads within a task to exit.

Change in the name of a thread state: Undead -> JoinMe.
 
2445 6221 d 18 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2444 6222 d 9 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...
 
2443 6222 d 10 h jermar /trunk/ sscc -> suncc
