2131 6485 d 23 h decky /branches/ add development branches  
2119 6533 d 1 h decky /trunk/kernel/generic/src/syscall/ explicit typecast  
2071 6551 d 19 h jermar /trunk/ (c) versus (C)  
1862 6689 d 23 h jermar /trunk/kernel/ sparc64 work.
Kernel syscall support.
Modify the preemptive_handler for the use by syscalls.
 
1787 6741 d 22 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6748 d 23 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6770 d 1 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1597 6777 d 7 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1579 6778 d 18 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 6782 d 18 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1448 6784 d 23 h palkovsky /kernel/trunk/generic/src/syscall/ Better SYS_IO  
1386 6793 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 6797 d 16 h vana /kernel/trunk/generic/src/syscall/ kernel changes for uspace FB driver  
1329 6799 d 23 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1318 6800 d 20 h vana /kernel/trunk/ Sysinfo userspace interface  
1306 6803 d 0 h jermar /kernel/trunk/generic/ Add SYS_AS_AREA_DESTROY syscall.
Add few error codes to errno.h
and change as.c accordingly.
 
1297 6807 d 1 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 6808 d 4 h jermar /kernel/trunk/generic/src/syscall/ Remove unused variable.  
1293 6809 d 1 h palkovsky /kernel/trunk/ Implemented mips memcpy (copy from gcc builtin memcpy).  
1278 6811 d 22 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1264 6813 d 4 h jermar /kernel/trunk/generic/ Improve Doxygen-comments.  
1258 6814 d 18 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 6818 d 4 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 6821 d 0 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 6821 d 22 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1191 6830 d 7 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.
 
1178 6831 d 23 h jermar /kernel/trunk/ Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM.
 
1176 6832 d 4 h jermar /kernel/trunk/generic/ Kernel support for SYS_GET_TASK_ID syscall.  
1118 6851 d 19 h jermar /kernel/trunk/generic/src/syscall/ Change syscall table.  
1112 6852 d 5 h palkovsky /kernel/trunk/ Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).
 
1109 6852 d 17 h jermar /kernel/trunk/ Basic futex. Prototype implementation.  
1100 6854 d 19 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 6855 d 20 h palkovsky /kernel/trunk/generic/ Reduced unnecessary IPC system calls.
Allow everything to be sync & async, everything is handled using messages.
 
1086 6856 d 17 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 6858 d 14 h jermar /kernel/trunk/ Support for user space threads.  
1040 6859 d 4 h palkovsky /kernel/trunk/generic/ Changed ipc to use spinlocks instead of mutexes again.
Fixed loading inits to set nameservice as the first loaded process.
Lot of TODO in ipc done.
 
1032 6859 d 15 h jermar /kernel/trunk/generic/ mmap() syscall.  
1027 6859 d 16 h palkovsky /kernel/trunk/ Implemented callback IPC call (connect_to_me).  
1024 6859 d 21 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.
