4384 5532 d 22 h svoboda /trunk/kernel/generic/src/ Clean up various log messages, mostly udebug.  
4252 5571 d 0 h decky /trunk/kernel/ move event notification to the ipc directory (where it probably belogs to, side-by-side to IRQ notifications)
cleanup the notification code a little bit (there is probably no need to allocate two structured dynamically)		  
4180 5584 d 5 h decky /trunk/kernel/generic/ Unicode aware printf and family functions
(this breaks some things, but will be fixed soon)		  
4173 5584 d 22 h jermar /trunk/ Revive kernel notifications.  
4148 5590 d 9 h decky /trunk/ as kernel little brother drivers are not needed anymore, the device numbers do not have to be correlated between kernel and uspace in any way
introduce new syscall sys_device_assign_devno() for generating system-wide unique device numbers for uspace		  
3983 5607 d 5 h svoboda /trunk/ task_set_name() syscall so that we can have names (for userspace-loaded) tasks again.  
3844 5635 d 22 h decky /trunk/ silent kernel console output when user space console is active  
3842 5636 d 1 h decky /trunk/kernel/generic/src/ make sys_klog atomic  
3819 5641 d 23 h jermar /trunk/ Introduce a new syscall: SYS_IPC_FORWARD_SLOW.  
3707 5682 d 1 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)		  
3614 5706 d 8 h svoboda /trunk/kernel/generic/src/syscall/ Add another stopping point.  
3603 5706 d 21 h svoboda /trunk/ Stoppability sections must be much smaller (design error). Also fix deadlock in udebug_stop(). Fix pause functionality in tracer.  
3438 5772 d 7 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3222 5843 d 4 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3113 5874 d 20 h decky /trunk/kernel/generic/ rename SYS_IO to SYS_KLOG
do not notify uspace klog with every single character, introduce some latency		  
3097 5877 d 0 h decky /trunk/kernel/ resurrect klog  
3096 5877 d 1 h svoboda /trunk/kernel/generic/src/syscall/ Fix malloc(0) in sys_io()  
3064 5878 d 5 h decky /trunk/kernel/generic/src/syscall/ change SYS_IO semantics
add SYS_TASK_SPAWN
proper printf formatting		  
2619 6073 d 22 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 6074 d 10 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 6075 d 7 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 6078 d 3 h jermar /trunk/ Start support for six syscall arguments.
This breaks all architectures.		  
2467 6234 d 2 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.		  
2216 6300 d 23 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2187 6302 d 7 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2119 6362 d 5 h decky /trunk/kernel/generic/src/syscall/ explicit typecast  
2089 6370 d 6 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6380 d 23 h jermar /trunk/ (c) versus (C)  
1888 6506 d 2 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1862 6519 d 3 h jermar /trunk/kernel/ sparc64 work.
Kernel syscall support.
Modify the preemptive_handler for the use by syscalls.		  
1822 6550 d 8 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 6571 d 1 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6578 d 2 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1708 6596 d 8 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1702 6599 d 5 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1597 6606 d 11 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1579 6607 d 22 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 6611 d 21 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1448 6614 d 2 h palkovsky /kernel/trunk/generic/src/syscall/ Better SYS_IO  
1386 6622 d 5 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.
