4387 5540 d 9 h svoboda /trunk/kernel/generic/src/ Reduce Udebug overhead with some nifty tricks.  
4385 5541 d 7 h svoboda /trunk/kernel/generic/src/syscall/ Revert accidental change.  
4384 5541 d 7 h svoboda /trunk/kernel/generic/src/ Clean up various log messages, mostly udebug.  
4252 5579 d 9 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 5592 d 14 h decky /trunk/kernel/generic/ Unicode aware printf and family functions
(this breaks some things, but will be fixed soon)
 
4173 5593 d 7 h jermar /trunk/ Revive kernel notifications.  
4148 5598 d 18 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 5615 d 14 h svoboda /trunk/ task_set_name() syscall so that we can have names (for userspace-loaded) tasks again.  
3844 5644 d 7 h decky /trunk/ silent kernel console output when user space console is active  
3842 5644 d 10 h decky /trunk/kernel/generic/src/ make sys_klog atomic  
3819 5650 d 9 h jermar /trunk/ Introduce a new syscall: SYS_IPC_FORWARD_SLOW.  
3707 5690 d 10 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)
 
3614 5714 d 17 h svoboda /trunk/kernel/generic/src/syscall/ Add another stopping point.  
3603 5715 d 7 h svoboda /trunk/ Stoppability sections must be much smaller (design error). Also fix deadlock in udebug_stop(). Fix pause functionality in tracer.  
3438 5780 d 17 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3222 5851 d 13 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3113 5883 d 6 h decky /trunk/kernel/generic/ rename SYS_IO to SYS_KLOG
do not notify uspace klog with every single character, introduce some latency
 
3097 5885 d 10 h decky /trunk/kernel/ resurrect klog  
3096 5885 d 10 h svoboda /trunk/kernel/generic/src/syscall/ Fix malloc(0) in sys_io()  
3064 5886 d 14 h decky /trunk/kernel/generic/src/syscall/ change SYS_IO semantics
add SYS_TASK_SPAWN
proper printf formatting
 
2619 6082 d 7 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 6082 d 20 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 6083 d 17 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 6086 d 13 h jermar /trunk/ Start support for six syscall arguments.
This breaks all architectures.
 
2467 6242 d 11 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2216 6309 d 9 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2187 6310 d 16 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2119 6370 d 14 h decky /trunk/kernel/generic/src/syscall/ explicit typecast  
2089 6378 d 15 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6389 d 8 h jermar /trunk/ (c) versus (C)  
1888 6514 d 12 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1862 6527 d 12 h jermar /trunk/kernel/ sparc64 work.
Kernel syscall support.
Modify the preemptive_handler for the use by syscalls.
 
1822 6558 d 18 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 6579 d 10 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6586 d 12 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1708 6604 d 18 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1702 6607 d 14 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1597 6614 d 20 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1579 6616 d 7 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 6620 d 7 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.
