2465 6175 d 6 h jermar /trunk/ Merge arm32 into trunk.  
2462 6177 d 1 h jermar /trunk/kernel/ Replace gcc-specific __FUNCTION__ with C99 __func__.
suncc's xregs=no%float can be used only on sparc64.
 
2460 6177 d 1 h jermar /trunk/kernel/ Better infrastructure for building with different compilers.
Separate ICC_CFLAGS added, SUNCC_CFLAGS extended.
 
2459 6177 d 4 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 6177 d 5 h jermar /trunk/kernel/arch/mips32/ Fix mips32 build script.
Replace CFLAGS with GCC_CFLAGS.
 
2457 6177 d 5 h jermar /trunk/kernel/arch/ia32xen/src/smp/ Fix ia32xen so that it can be built.  
2455 6178 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 6178 d 0 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 6178 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 6178 d 7 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 6179 d 1 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2447 6182 d 5 h jermar /trunk/kernel/generic/src/main/ Split accidently joined lines.  
2446 6182 d 5 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 6182 d 7 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2444 6182 d 22 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...
 
2443 6182 d 22 h jermar /trunk/ sscc -> suncc  
2442 6182 d 23 h jermar /trunk/ Add dummy option for Sun Studio C Compiler.
For each architecture, offer only compilers that support the target.
 
2441 6183 d 0 h decky /trunk/kernel/ fix ICC compilation  
2440 6183 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 6183 d 0 h decky /trunk/kernel/arch/ia32/src/ fix ICC compilation  
2438 6183 d 0 h decky /trunk/ update for new compiler configuration scheme  
2437 6183 d 0 h decky /trunk/ experimental support for ICC
(the sources has to be modified to avoid ICC compiler warnings)
 
2436 6184 d 1 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 6196 d 11 h jermar /trunk/ Improve comments for the IPC subsystem.
Fix formatting and indentation.
 
2321 6204 d 6 h decky /trunk/ keep mouse state in i8042_grab, unify keyboard and mouse IRQ handler
(this fixes ticket #12)
 
2319 6204 d 11 h decky /trunk/kernel/generic/src/console/ run mcall only on active CPUs  
2317 6204 d 22 h decky /trunk/kernel/arch/ia32/include/ remove outstanding move  
2316 6204 d 22 h decky /trunk/kernel/arch/ia32/include/ remove forgotten movs  
2314 6204 d 23 h decky /trunk/kernel/arch/ia32/include/ allow to compile with -O0  
2310 6207 d 2 h jermar /trunk/kernel/generic/ Cleanup the waitq_wakeup() interface.
Replace numeric constants (i.e. 0)
and boolean constants (i.e. false) with
more readable WAKEUP_FIRST. Also change the
type of the second argument of waitq_wakeup()
to a newly introduced type wakeup_mode_t.

Fix behaviour of waitq_wakeup() in case
that WAKEUP_ALL semantics is required
but no threads are sleeping in the wait
queue. This is a similar fix to that of
Jan Hudecek committed in the RCU branch,
but, IMHO, is more straightforward and
also doesn't eat up previous missed
wakeups.
 
2302 6210 d 4 h decky /trunk/ force VGA palette to 3:2:3 palette on 8 bpp modes
(this fixes ticket #33)
 
2285 6219 d 10 h jermar /trunk/kernel/generic/src/proc/ Formatting and indentation fixes.  
2275 6224 d 2 h decky /trunk/kernel/generic/ add fancy uptime kconsole command  
2272 6225 d 3 h jermar /trunk/kernel/ Indentation and formatting fixes.  
2268 6226 d 2 h jermar /trunk/kernel/generic/ Document and assert proper usage of THREAD_FLAG_WIRED.
Original patch by Jan Hudecek.
 
2267 6227 d 2 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix indentation.  
2266 6227 d 2 h jermar /trunk/kernel/arch/sparc64/src/mm/ Add few assertions to tsb.c and clean it up a little bit.  
2252 6229 d 0 h jermar /trunk/kernel/arch/sparc64/src/mm/ Move one MEMBAR instruction from a delay slot,
which is, due to SF Erratum #51, a potentionally
dangerous place for a MEMBAR to be.
 
2233 6235 d 0 h decky /trunk/kernel/arch/ use the hlt instruction more properly  
2232 6235 d 1 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM
