3888 5595 d 8 h jermar /tags/0.4.0/ Tag 0.4.0.  
3844 5609 d 1 h decky /trunk/ silent kernel console output when user space console is active  
3842 5609 d 3 h decky /trunk/kernel/generic/src/ make sys_klog atomic  
3819 5615 d 2 h jermar /trunk/ Introduce a new syscall: SYS_IPC_FORWARD_SLOW.  
3707 5655 d 3 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)		  
3614 5679 d 11 h svoboda /trunk/kernel/generic/src/syscall/ Add another stopping point.  
3603 5680 d 0 h svoboda /trunk/ Stoppability sections must be much smaller (design error). Also fix deadlock in udebug_stop(). Fix pause functionality in tracer.  
3438 5745 d 10 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3222 5816 d 6 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3113 5847 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 5850 d 3 h decky /trunk/kernel/ resurrect klog  
3096 5850 d 3 h svoboda /trunk/kernel/generic/src/syscall/ Fix malloc(0) in sys_io()  
3064 5851 d 7 h decky /trunk/kernel/generic/src/syscall/ change SYS_IO semantics
add SYS_TASK_SPAWN
proper printf formatting		  
2619 6047 d 1 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 6047 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 6048 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 6051 d 6 h jermar /trunk/ Start support for six syscall arguments.
This breaks all architectures.		  
2467 6207 d 4 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.		  
2216 6274 d 2 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2187 6275 d 9 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2119 6335 d 7 h decky /trunk/kernel/generic/src/syscall/ explicit typecast  
2089 6343 d 9 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6354 d 2 h jermar /trunk/ (c) versus (C)  
1888 6479 d 5 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1862 6492 d 5 h jermar /trunk/kernel/ sparc64 work.
Kernel syscall support.
Modify the preemptive_handler for the use by syscalls.		  
1822 6523 d 11 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 6544 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6551 d 5 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1708 6569 d 11 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1702 6572 d 8 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1597 6579 d 14 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1579 6581 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 6585 d 0 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1448 6587 d 5 h palkovsky /kernel/trunk/generic/src/syscall/ Better SYS_IO  
1386 6595 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 6599 d 23 h vana /kernel/trunk/generic/src/syscall/ kernel changes for uspace FB driver  
1329 6602 d 5 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1318 6603 d 2 h vana /kernel/trunk/ Sysinfo userspace interface  
1306 6605 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 6609 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.
