4581 5518 d 0 h mejdrech /branches/network/ Net: synchronized with trunk rev.4580  
4263 5596 d 23 h mejdrech /branches/network/ Net: merged with trunk:4261  
4153 5618 d 23 h mejdrech /branches/network/ Networking: merged with trunk changes  
3386 5815 d 2 h decky /branches/network/ add new network branch (copy of current trunk)  
3222 5872 d 2 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3113 5903 d 19 h decky /trunk/kernel/generic/ rename SYS_IO to SYS_KLOG
do not notify uspace klog with every single character, introduce some latency		  
3097 5905 d 23 h decky /trunk/kernel/ resurrect klog  
3096 5905 d 23 h svoboda /trunk/kernel/generic/src/syscall/ Fix malloc(0) in sys_io()  
3064 5907 d 3 h decky /trunk/kernel/generic/src/syscall/ change SYS_IO semantics
add SYS_TASK_SPAWN
proper printf formatting		  
2619 6102 d 21 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 6103 d 9 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 6104 d 6 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 6107 d 2 h jermar /trunk/ Start support for six syscall arguments.
This breaks all architectures.		  
2467 6263 d 1 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.		  
2216 6329 d 22 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2187 6331 d 5 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2119 6391 d 3 h decky /trunk/kernel/generic/src/syscall/ explicit typecast  
2089 6399 d 5 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6409 d 22 h jermar /trunk/ (c) versus (C)  
1888 6535 d 1 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1862 6548 d 1 h jermar /trunk/kernel/ sparc64 work.
Kernel syscall support.
Modify the preemptive_handler for the use by syscalls.		  
1822 6579 d 7 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 6600 d 0 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6607 d 1 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1708 6625 d 7 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1702 6628 d 4 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1597 6635 d 10 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1579 6636 d 20 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 6640 d 20 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1448 6643 d 1 h palkovsky /kernel/trunk/generic/src/syscall/ Better SYS_IO  
1386 6651 d 4 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 6655 d 19 h vana /kernel/trunk/generic/src/syscall/ kernel changes for uspace FB driver  
1329 6658 d 1 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1318 6658 d 22 h vana /kernel/trunk/ Sysinfo userspace interface  
1306 6661 d 2 h jermar /kernel/trunk/generic/ Add SYS_AS_AREA_DESTROY syscall.
Add few error codes to errno.h
and change as.c accordingly.		  
1297 6665 d 3 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 6666 d 7 h jermar /kernel/trunk/generic/src/syscall/ Remove unused variable.  
1293 6667 d 3 h palkovsky /kernel/trunk/ Implemented mips memcpy (copy from gcc builtin memcpy).  
1288 6667 d 6 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 6670 d 0 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.
