3623 5724 d 3 h svoboda /branches/tracing/ Merge latest trunk changes into tracing.  
3606 5725 d 15 h svoboda /branches/tracing/ Merge latest trunk changes into tracing.  
3431 5791 d 17 h svoboda /branches/tracing/kernel/ Add configuration option CONFIG_UDEBUG to compile udebug in the kernel or not.  
3425 5792 d 5 h svoboda /branches/tracing/ Merge latest trunk changes into tracing (broken)  
3424 5792 d 16 h svoboda /branches/tracing/ Merge trunk changes up to r3180 into tracing  
3018 5902 d 21 h svoboda /branches/tracing/ Isolate udebug-related thread_t fields into udebug_thread_t  
2901 5919 d 17 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 5953 d 19 h svoboda /branches/tracing/kernel/generic/ Add REGS_READ and REGS_WRITE debug methods to access userspace register state (no effect yet)  
2813 5954 d 1 h svoboda /branches/tracing/ Move debug call preprocessing from ipc/sysipc.c to udebug/udebug_ipc.c  
2808 5954 d 18 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2805 5955 d 22 h svoboda /branches/tracing/ add ipc call to retrieve syscall arguments  
2804 5956 d 0 h svoboda /branches/tracing/kernel/generic/ allow for attaching to tasks with sleeping threads  
2801 5956 d 4 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2799 5956 d 6 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 5964 d 22 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2619 6092 d 17 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 6093 d 5 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 6094 d 2 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 6096 d 22 h jermar /trunk/ Start support for six syscall arguments.
This breaks all architectures.		  
2467 6252 d 20 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.		  
2216 6319 d 18 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2187 6321 d 1 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2119 6380 d 23 h decky /trunk/kernel/generic/src/syscall/ explicit typecast  
2089 6389 d 1 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6399 d 18 h jermar /trunk/ (c) versus (C)  
1888 6524 d 21 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1862 6537 d 21 h jermar /trunk/kernel/ sparc64 work.
Kernel syscall support.
Modify the preemptive_handler for the use by syscalls.		  
1822 6569 d 3 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 6589 d 20 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6596 d 21 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1708 6615 d 3 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1702 6618 d 0 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1597 6625 d 6 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1579 6626 d 16 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 6630 d 16 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1448 6632 d 21 h palkovsky /kernel/trunk/generic/src/syscall/ Better SYS_IO  
1386 6641 d 0 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 6645 d 15 h vana /kernel/trunk/generic/src/syscall/ kernel changes for uspace FB driver  
1329 6647 d 21 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1318 6648 d 18 h vana /kernel/trunk/ Sysinfo userspace interface
