3222 5812 d 6 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3113 5843 d 23 h decky /trunk/kernel/generic/ rename SYS_IO to SYS_KLOG
do not notify uspace klog with every single character, introduce some latency		  
3097 5846 d 3 h decky /trunk/kernel/ resurrect klog  
3096 5846 d 3 h svoboda /trunk/kernel/generic/src/syscall/ Fix malloc(0) in sys_io()  
3064 5847 d 7 h decky /trunk/kernel/generic/src/syscall/ change SYS_IO semantics
add SYS_TASK_SPAWN
proper printf formatting		  
2619 6043 d 0 h jermar /trunk/ Modify ipc_answer_*() to make use of all six syscall arguments. The recommended
means of answering calls is via the ipc_answer_m() macros (where m denotes the
number of return arguments) that automatically decide between the fast register
version or the slow universal version of ipc_answer().		  
2618 6043 d 13 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 6044 d 10 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 6047 d 6 h jermar /trunk/ Start support for six syscall arguments.
This breaks all architectures.		  
2467 6203 d 4 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.		  
2216 6270 d 2 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2187 6271 d 9 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2119 6331 d 7 h decky /trunk/kernel/generic/src/syscall/ explicit typecast  
2071 6350 d 1 h jermar /trunk/ (c) versus (C)  
1862 6488 d 5 h jermar /trunk/kernel/ sparc64 work.
Kernel syscall support.
Modify the preemptive_handler for the use by syscalls.		  
1787 6540 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6547 d 5 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6568 d 8 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1597 6575 d 14 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1579 6577 d 0 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 0 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1448 6583 d 5 h palkovsky /kernel/trunk/generic/src/syscall/ Better SYS_IO  
1386 6591 d 8 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 6595 d 23 h vana /kernel/trunk/generic/src/syscall/ kernel changes for uspace FB driver  
1329 6598 d 5 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1318 6599 d 2 h vana /kernel/trunk/ Sysinfo userspace interface  
1306 6601 d 6 h jermar /kernel/trunk/generic/ Add SYS_AS_AREA_DESTROY syscall.
Add few error codes to errno.h
and change as.c accordingly.		  
1297 6605 d 7 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 6606 d 10 h jermar /kernel/trunk/generic/src/syscall/ Remove unused variable.  
1293 6607 d 7 h palkovsky /kernel/trunk/ Implemented mips memcpy (copy from gcc builtin memcpy).  
1278 6610 d 4 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1264 6611 d 10 h jermar /kernel/trunk/generic/ Improve Doxygen-comments.  
1258 6613 d 0 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 6616 d 10 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 6619 d 6 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 6620 d 4 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1191 6628 d 13 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.		  
1178 6630 d 5 h jermar /kernel/trunk/ Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM.		  
1176 6630 d 10 h jermar /kernel/trunk/generic/ Kernel support for SYS_GET_TASK_ID syscall.  
1118 6650 d 1 h jermar /kernel/trunk/generic/src/syscall/ Change syscall table.
