2470 6192 d 0 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 6192 d 2 h jermar /trunk/uspace/libc/generic/ Fix a bug in userspace thread_create() that confused success of the
syscall with failure.
 
2468 6192 d 3 h jermar /trunk/ Remove some forgotten \r from arm32 files.
Formatting changes.
Add some correct BOOT_mips32_* guards.
 
2467 6192 d 4 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2466 6196 d 8 h mencl /branches/rcu/kernel/ Added forgoten favl.h and favl.c and changed balance atribute of avl
tree to int8_t.
 
2465 6197 d 7 h jermar /trunk/ Merge arm32 into trunk.  
2464 6198 d 2 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 6198 d 12 h hudecek /branches/rcu/kernel/genarch/src/kbd/ Fixed a typo  
2462 6199 d 1 h jermar /trunk/kernel/ Replace gcc-specific __FUNCTION__ with C99 __func__.
suncc's xregs=no%float can be used only on sparc64.
 
2461 6199 d 2 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 6199 d 2 h jermar /trunk/kernel/ Better infrastructure for building with different compilers.
Separate ICC_CFLAGS added, SUNCC_CFLAGS extended.
 
2459 6199 d 5 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 6199 d 5 h jermar /trunk/kernel/arch/mips32/ Fix mips32 build script.
Replace CFLAGS with GCC_CFLAGS.
 
2457 6199 d 5 h jermar /trunk/kernel/arch/ia32xen/src/smp/ Fix ia32xen so that it can be built.  
2456 6200 d 0 h hudecek /branches/rcu/kernel/ Model use of RCU  
2455 6200 d 0 h jermar /trunk/kernel/ Some non-C files (e.g. .S and linker scripts) must be still "compiled" with gcc and GCC_CFLAGS.  
2454 6200 d 1 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 6200 d 6 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 6200 d 8 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 6201 d 2 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2450 6202 d 4 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 6203 d 13 h decky /trunk/uspace/rd/ remove unnecessary includes  
2448 6204 d 5 h jermar /branches/arm/kernel/arch/arm32/src/cpu/ Start the CPU identification string with cpu[0-9].  
2447 6204 d 6 h jermar /trunk/kernel/generic/src/main/ Split accidently joined lines.  
2446 6204 d 6 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 6204 d 8 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2444 6204 d 22 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...
 
2443 6204 d 23 h jermar /trunk/ sscc -> suncc  
2442 6205 d 0 h jermar /trunk/ Add dummy option for Sun Studio C Compiler.
For each architecture, offer only compilers that support the target.
 
2441 6205 d 0 h decky /trunk/kernel/ fix ICC compilation  
2440 6205 d 0 h jermar /trunk/kernel/generic/ Fix the problem with sys_thread_create() by splitting the create and attach functionality of
thread_create(). Now it is possible to specify a flag that will cause thread_create() to only allocate and
initialize the thread structure. A call to thread_attach() will make the thread visible to the system.
This arrangement makes it easier to undo creation of a thread in case of a failure in sys_thread_create().
 
2439 6205 d 1 h decky /trunk/kernel/arch/ia32/src/ fix ICC compilation  
2438 6205 d 1 h decky /trunk/ update for new compiler configuration scheme  
2437 6205 d 1 h decky /trunk/ experimental support for ICC
(the sources has to be modified to avoid ICC compiler warnings)
 
2436 6206 d 2 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.
 
2435 6208 d 15 h jelen /branches/fs/ Doxygen documentation format  
2434 6208 d 17 h jelen /branches/fs/uspace/cat/ Cat user file library update  
2433 6208 d 17 h jelen /branches/fs/uspace/ Revert changes from migration to trunk + file user interface  
2432 6208 d 17 h jelen /branches/fs/boot/arch/ Boot config for ramdisk  
2431 6209 d 0 h mencl /branches/rcu/kernel/ Repaired extavl and extavlrel data structures, added benchmark tests for avl based data structures and
simulating timeout mechanismus
