2516 6126 d 5 h vana /trunk/kernel/ IA64 rest of neaded changes to work with simics keyboard  
2515 6126 d 5 h vana /trunk/kernel/arch/ia64/include/ IA64 legacy I/O  
2514 6126 d 5 h vana /trunk/kernel/arch/ia64/ IA64 Makefile changes for simics  
2513 6126 d 5 h vana /trunk/kernel/arch/ia64/src/ IA64 simics keyboard support  
2512 6126 d 5 h vana /trunk/kernel/arch/ia64/src/ IA64 loader parameter  
2510 6130 d 6 h jermar /trunk/kernel/ Experimental support for the cgsix framebuffer, which is found on old Ultra 1
worksations, and the SBUS bus and devices. Not tested.
 
2505 6163 d 16 h jermar /trunk/kernel/genarch/src/softint/ Minor cleanup of softint.  
2504 6168 d 6 h jermar /trunk/kernel/generic/ Give the AVL tree walkers the possibility to take an argument.
Each walker is now supposed to return a bool value to support walk termination.

Switch over from the tasks_btree B+tree to tasks_tree AVL tree.
This makes the fix for ticket #48 complete.
 
2503 6168 d 7 h jermar /trunk/kernel/generic/src/adt/ Get rid of code duplicities in the insert path into an AVL tree.  
2502 6168 d 12 h jermar /trunk/kernel/generic/ Replace the threads_btree B+tree with an AVL tree. The new variable is called
threads_tree. For printing list of threads, use the new AVL tree walker
mechanism.

This solves half of ticket #48.
 
2501 6168 d 12 h jermar /trunk/kernel/generic/ Add explicit type for an AVL tree key.
Add function to walk an AVL tree using a supplied walker.
 
2500 6168 d 14 h jermar /trunk/kernel/ Make the kernel compile again after integrating the AVL tree.
Integrate with tests, add the AVL tree implementation author into AUTHORS.
 
2499 6168 d 14 h jermar /trunk/kernel/ Import the AVL tree implementation from the RCU branch.  
2494 6186 d 5 h jermar /trunk/kernel/generic/ Implement a new mechanism for copying data between two address spaces based on
IPC. New system method IPC_M_DATA_SEND is introduced. The implementation is
generic and does not make use of any possible architecture optimizations such as
direct copy from one address space to another.
 
2493 6186 d 9 h jermar /trunk/kernel/generic/include/ipc/ Collapse IPC method numbers.  
2489 6193 d 11 h jermar /trunk/ Allow HelenOS to be built by a native gcc on Solaris.  
2487 6195 d 7 h jermar /trunk/kernel/generic/src/proc/ Kernel stack address was printed twice.  
2482 6200 d 1 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.
 
2477 6207 d 3 h kebrt /trunk/kernel/arch/arm32/src/ fixes bug causing crash in tester 'thread1' test  
2476 6207 d 5 h jermar /trunk/ Cleanup.  
2472 6210 d 6 h jermar /trunk/kernel/generic/src/ipc/ Some left-over stuff from the last commit (IPC cleanup and improved
comments.)
 
2471 6210 d 6 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2470 6214 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().
 
2467 6214 d 8 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2465 6219 d 11 h jermar /trunk/ Merge arm32 into trunk.  
2462 6221 d 5 h jermar /trunk/kernel/ Replace gcc-specific __FUNCTION__ with C99 __func__.
suncc's xregs=no%float can be used only on sparc64.
 
2460 6221 d 6 h jermar /trunk/kernel/ Better infrastructure for building with different compilers.
Separate ICC_CFLAGS added, SUNCC_CFLAGS extended.
 
2459 6221 d 9 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 6221 d 9 h jermar /trunk/kernel/arch/mips32/ Fix mips32 build script.
Replace CFLAGS with GCC_CFLAGS.
 
2457 6221 d 9 h jermar /trunk/kernel/arch/ia32xen/src/smp/ Fix ia32xen so that it can be built.  
2455 6222 d 4 h jermar /trunk/kernel/ Some non-C files (e.g. .S and linker scripts) must be still "compiled" with gcc and GCC_CFLAGS.  
2454 6222 d 4 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 6222 d 10 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 6222 d 12 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 6223 d 6 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2447 6226 d 10 h jermar /trunk/kernel/generic/src/main/ Split accidently joined lines.  
2446 6226 d 10 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 6226 d 11 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2444 6227 d 2 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...
 
2443 6227 d 3 h jermar /trunk/ sscc -> suncc
