1862 6488 d 22 h jermar /trunk/kernel/ sparc64 work.
Kernel syscall support.
Modify the preemptive_handler for the use by syscalls.
 
1822 6520 d 4 h jermar /trunk/ sparc64 work.
1. Formatting fixes.
2. When writing to DMMU ASI's, simple membar() can be used in place of flush().
3. Substantial changes in the way the TLB is taken over.
4. Remove unneeded functions.

This is the first revision that also runs on a real world Ultra 5 with UltraSPARC IIi
processor.

Note that 3. needs further work as the current implementation depends on the fact
that the compiler will use registers for local variables in take_over_tlb_and_tt().
Rewrite of that function into assembly is to follow.
 
1787 6540 d 21 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6547 d 22 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1708 6566 d 4 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1702 6569 d 1 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1597 6576 d 7 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1579 6577 d 17 h jermar /kernel/trunk/generic/ Framework for task_kill().
Some pieces (e.g. implementation of ktask_cleanup() kernel thread and
task_destroy() function) are missing.
Changed locking order for task lock, threads_lock and thread lock from
threads_lock, thread lock, task lock to task lock, threads_lock, thread lock.
 
1474 6581 d 17 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1448 6583 d 22 h palkovsky /kernel/trunk/generic/src/syscall/ Better SYS_IO  
1386 6592 d 1 h palkovsky /kernel/trunk/ Fixed mips bug fith TLS register not being properly saved on syscall context
switch.
Reverted SYS_IO, so that it could be used on machines without fb.
 
1362 6596 d 16 h vana /kernel/trunk/generic/src/syscall/ kernel changes for uspace FB driver  
1329 6598 d 22 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1318 6599 d 19 h vana /kernel/trunk/ Sysinfo userspace interface  
1306 6601 d 23 h jermar /kernel/trunk/generic/ Add SYS_AS_AREA_DESTROY syscall.
Add few error codes to errno.h
and change as.c accordingly.
 
1297 6606 d 0 h jermar /kernel/trunk/ Add SYS_CAP_GRANT and SYS_CAP_REVOKE syscalls.
Move SYS_PREEMPT_CONTROL to ddi.c.
Add some comments and fix some small issues.
 
1294 6607 d 3 h jermar /kernel/trunk/generic/src/syscall/ Remove unused variable.  
1293 6608 d 0 h palkovsky /kernel/trunk/ Implemented mips memcpy (copy from gcc builtin memcpy).  
1288 6608 d 3 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.
 
1278 6610 d 21 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.
