2618 6026 d 0 h jermar /trunk/ Modify asynchronous IPC to make use of all six syscall arguments. The preferred
means of asynchronous communication is now via the set of ipc_call_async_m()
macros, where m is the number of payload arguments passed to the kernel. These
macros will automatically decide between the fast and the universal slow version
of ipc_call_async.		  
2615 6026 d 21 h jermar /trunk/ Modify synchronous IPC to make use of all six syscall arguments. The preferred
means of synchronous communication is now via the set of ipc_call_sync_m_n()
macros, where m is the number of payload arguments passed to the kernel and n is
the number of return values. These macros will automatically decide between the
fast and the universal slow version of ipc_call_sync.		  
2605 6029 d 17 h jermar /trunk/ Start support for six syscall arguments.
This breaks all architectures.		  
2467 6185 d 16 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.

1862 6470 d 16 h jermar /trunk/kernel/ sparc64 work.
Kernel syscall support.

1787 6522 d 15 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6529 d 16 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6550 d 19 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1597 6558 d 1 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1579 6559 d 11 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 6563 d 11 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1448 6565 d 16 h palkovsky /kernel/trunk/generic/src/syscall/ Better SYS_IO  
1386 6573 d 19 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 6578 d 10 h vana /kernel/trunk/generic/src/syscall/ kernel changes for uspace FB driver  
1329 6580 d 16 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1318 6581 d 13 h vana /kernel/trunk/ Sysinfo userspace interface  
1306 6583 d 17 h jermar /kernel/trunk/generic/ Add SYS_AS_AREA_DESTROY syscall.
Add few error codes to errno.h
and change as.c accordingly.		  
1297 6587 d 18 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 6588 d 22 h jermar /kernel/trunk/generic/src/syscall/ Remove unused variable.  
1293 6589 d 18 h palkovsky /kernel/trunk/ Implemented mips memcpy (copy from gcc builtin memcpy).  
1278 6592 d 15 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1264 6593 d 21 h jermar /kernel/trunk/generic/ Improve Doxygen-comments.  
1258 6595 d 11 h palkovsky /kernel/trunk/ Added support for IRQ notifiactions.
- seems to work correctly on ia32, amd64
- the mips kbd probably lowers interrupts when the char is read from
the port, we will have to find a way how to deal with it.		  
1235 6598 d 22 h jermar /kernel/trunk/generic/ Implementation of SYS_AS_AREA_ACCEPT and SYS_AS_AREA_SEND syscalls.
Note that these replace previously declared SYS_AS_AREA_SHARE_APPROVE
and SYS_AS_AREA_SHARE_PERFORM.		  
1227 6601 d 17 h jermar /kernel/trunk/ Reorganize syscall names to better correspond to kernel architecture.
Add dummy placeholders for SYS_AS_AREA_SHARE_APPROVE and
SYS_AS_AREA_SHARE_PERFORM syscalls.		  
1212 6602 d 15 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1191 6611 d 0 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.		  
1178 6612 d 17 h jermar /kernel/trunk/ Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM.		  
1176 6612 d 21 h jermar /kernel/trunk/generic/ Kernel support for SYS_GET_TASK_ID syscall.  
1118 6632 d 12 h jermar /kernel/trunk/generic/src/syscall/ Change syscall table.  
1112 6632 d 23 h palkovsky /kernel/trunk/ Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).		  
1109 6633 d 11 h jermar /kernel/trunk/ Basic futex. Prototype implementation.  
1100 6635 d 13 h palkovsky /kernel/trunk/ Cleanup of spinlocks, now compiles both ia32 and amd64 with
and without DEBUG_SPINLOCKS. Made spinlocks inline.
Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32).
Made slightly faster syscall for ia32.
Made better interrupt routines for ia32.
Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32.
Aligned interrupt handlers on ia32,amd64, this should prevent problems
with different instruction lengths.		  
1090 6636 d 14 h palkovsky /kernel/trunk/generic/ Reduced unnecessary IPC system calls.
Allow everything to be sync & async, everything is handled using messages.		  
1086 6637 d 10 h palkovsky /kernel/trunk/generic/ Untested better IPC functions.
* There is some bug in MIPS, unpredicatbly sometimes the thread gets mapped
different frame for stack.		  
1066 6639 d 8 h jermar /kernel/trunk/ Support for user space threads.
