3210 5843 d 8 h svoboda /branches/dynload/ Introduce SMC_COHERENCE syscall  
3203 5844 d 7 h svoboda /branches/dynload/ Move stuff related to running programs to a separate source file proc/program.c  
3190 5850 d 5 h svoboda /branches/dynload/ Remove vestiges of loading code coming from trunk  
3153 5864 d 5 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3150 5864 d 5 h svoboda /branches/dynload/ Merge trunk changes up to r3090 into dynload (still broken)  
3149 5864 d 6 h svoboda /branches/dynload/ Merge trunk changes up to r3071 into dynload (broken)  
3001 5886 d 4 h svoboda /branches/dynload/kernel/generic/ Kernel support for running programs from userspace.  
2984 5889 d 5 h svoboda /branches/dynload/ Add as_area_change_flags() syscall and libc wrapper. Implementation limited to non-shared areas of anonymous memory.  
2952 5893 d 23 h svoboda /branches/dynload/ Load rtld.so with iloader and make it write to console with a stripped-down version of the C library  
2931 5896 d 6 h svoboda /branches/dynload/kernel/generic/src/syscall/ Fix format specifier when printing unknown syscall id  
2927 5896 d 9 h decky /branches/dynload/ added dynload branch  
2619 6072 d 21 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 6073 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 6074 d 6 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 6077 d 3 h jermar /trunk/ Start support for six syscall arguments.
This breaks all architectures.		  
2467 6233 d 1 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.		  
2216 6299 d 23 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2187 6301 d 6 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2119 6361 d 4 h decky /trunk/kernel/generic/src/syscall/ explicit typecast  
2089 6369 d 5 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6379 d 22 h jermar /trunk/ (c) versus (C)  
1888 6505 d 2 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1862 6518 d 2 h jermar /trunk/kernel/ sparc64 work.
Kernel syscall support.
Modify the preemptive_handler for the use by syscalls.		  
1822 6549 d 7 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 6570 d 0 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6577 d 1 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1708 6595 d 7 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1702 6598 d 4 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1597 6605 d 10 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1579 6606 d 21 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 6610 d 20 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1448 6613 d 2 h palkovsky /kernel/trunk/generic/src/syscall/ Better SYS_IO  
1386 6621 d 4 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 6625 d 19 h vana /kernel/trunk/generic/src/syscall/ kernel changes for uspace FB driver  
1329 6628 d 1 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1318 6628 d 23 h vana /kernel/trunk/ Sysinfo userspace interface  
1306 6631 d 3 h jermar /kernel/trunk/generic/ Add SYS_AS_AREA_DESTROY syscall.
Add few error codes to errno.h
and change as.c accordingly.		  
1297 6635 d 3 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.		  
1294 6636 d 7 h jermar /kernel/trunk/generic/src/syscall/ Remove unused variable.  
1293 6637 d 4 h palkovsky /kernel/trunk/ Implemented mips memcpy (copy from gcc builtin memcpy).
