3606 5700 d 2 h svoboda /branches/tracing/ Merge latest trunk changes into tracing.  
3431 5766 d 4 h svoboda /branches/tracing/kernel/ Add configuration option CONFIG_UDEBUG to compile udebug in the kernel or not.  
3425 5766 d 15 h svoboda /branches/tracing/ Merge latest trunk changes into tracing (broken)  
3424 5767 d 3 h svoboda /branches/tracing/ Merge trunk changes up to r3180 into tracing  
3018 5877 d 8 h svoboda /branches/tracing/ Isolate udebug-related thread_t fields into udebug_thread_t  
2901 5894 d 4 h svoboda /branches/tracing/ Split SYSCALL event into SYSCALL_B and SYSCALL_E, the extra event allows seeing long-running syscalls immediately, as well as calls with invalid syscall id  
2817 5928 d 6 h svoboda /branches/tracing/kernel/generic/ Add REGS_READ and REGS_WRITE debug methods to access userspace register state (no effect yet)  
2813 5928 d 12 h svoboda /branches/tracing/ Move debug call preprocessing from ipc/sysipc.c to udebug/udebug_ipc.c  
2808 5929 d 5 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2805 5930 d 9 h svoboda /branches/tracing/ add ipc call to retrieve syscall arguments  
2804 5930 d 11 h svoboda /branches/tracing/kernel/generic/ allow for attaching to tasks with sleeping threads  
2801 5930 d 15 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2799 5930 d 16 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 5939 d 9 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2619 6067 d 3 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 6067 d 16 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 6068 d 13 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 6071 d 9 h jermar /trunk/ Start support for six syscall arguments.
This breaks all architectures.		  
2467 6227 d 7 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.		  
2216 6294 d 5 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2187 6295 d 12 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2119 6355 d 10 h decky /trunk/kernel/generic/src/syscall/ explicit typecast  
2089 6363 d 11 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6374 d 4 h jermar /trunk/ (c) versus (C)  
1888 6499 d 8 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1862 6512 d 8 h jermar /trunk/kernel/ sparc64 work.
Kernel syscall support.
Modify the preemptive_handler for the use by syscalls.		  
1822 6543 d 13 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 6564 d 6 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6571 d 8 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1708 6589 d 14 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1702 6592 d 10 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1597 6599 d 16 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1579 6601 d 3 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 6605 d 3 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1448 6607 d 8 h palkovsky /kernel/trunk/generic/src/syscall/ Better SYS_IO  
1386 6615 d 10 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 6620 d 1 h vana /kernel/trunk/generic/src/syscall/ kernel changes for uspace FB driver  
1329 6622 d 8 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1318 6623 d 5 h vana /kernel/trunk/ Sysinfo userspace interface  
1306 6625 d 9 h jermar /kernel/trunk/generic/ Add SYS_AS_AREA_DESTROY syscall.
Add few error codes to errno.h
and change as.c accordingly.
