2467 6185 d 17 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2216 6252 d 15 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2187 6253 d 22 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2119 6313 d 20 h decky /trunk/kernel/generic/src/syscall/ explicit typecast  
2089 6321 d 21 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6332 d 14 h jermar /trunk/ (c) versus (C)  
1888 6457 d 18 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1862 6470 d 18 h jermar /trunk/kernel/ sparc64 work.
Kernel syscall support.
Modify the preemptive_handler for the use by syscalls.
 
1822 6501 d 23 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 6522 d 16 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6529 d 17 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1708 6547 d 23 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1702 6550 d 20 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1597 6558 d 2 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1579 6559 d 13 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 6563 d 12 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1448 6565 d 18 h palkovsky /kernel/trunk/generic/src/syscall/ Better SYS_IO  
1386 6573 d 20 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 6578 d 11 h vana /kernel/trunk/generic/src/syscall/ kernel changes for uspace FB driver  
1329 6580 d 17 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1318 6581 d 15 h vana /kernel/trunk/ Sysinfo userspace interface  
1306 6583 d 19 h jermar /kernel/trunk/generic/ Add SYS_AS_AREA_DESTROY syscall.
Add few error codes to errno.h
and change as.c accordingly.
 
1297 6587 d 19 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 6588 d 23 h jermar /kernel/trunk/generic/src/syscall/ Remove unused variable.  
1293 6589 d 19 h palkovsky /kernel/trunk/ Implemented mips memcpy (copy from gcc builtin memcpy).  
1288 6589 d 23 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.
 
1278 6592 d 16 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1264 6593 d 22 h jermar /kernel/trunk/generic/ Improve Doxygen-comments.  
1258 6595 d 13 h palkovsky /kernel/trunk/ Added support for IRQ notifiactions.
- seems to work correctly on ia32, amd64
- the mips kbd probably lowers interrupts when the char is read from
the port, we will have to find a way how to deal with it.
 
1235 6598 d 23 h jermar /kernel/trunk/generic/ Implementation of SYS_AS_AREA_ACCEPT and SYS_AS_AREA_SEND syscalls.
Note that these replace previously declared SYS_AS_AREA_SHARE_APPROVE
and SYS_AS_AREA_SHARE_PERFORM.
 
1227 6601 d 19 h jermar /kernel/trunk/ Reorganize syscall names to better correspond to kernel architecture.
Add dummy placeholders for SYS_AS_AREA_SHARE_APPROVE and
SYS_AS_AREA_SHARE_PERFORM syscalls.
 
1212 6602 d 17 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1191 6611 d 2 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.
 
1178 6612 d 18 h jermar /kernel/trunk/ Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM.
 
1176 6612 d 23 h jermar /kernel/trunk/generic/ Kernel support for SYS_GET_TASK_ID syscall.  
1118 6632 d 13 h jermar /kernel/trunk/generic/src/syscall/ Change syscall table.  
1112 6633 d 0 h palkovsky /kernel/trunk/ Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).
 
1109 6633 d 12 h jermar /kernel/trunk/ Basic futex. Prototype implementation.  
1100 6635 d 14 h palkovsky /kernel/trunk/ Cleanup of spinlocks, now compiles both ia32 and amd64 with
and without DEBUG_SPINLOCKS. Made spinlocks inline.
Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32).
Made slightly faster syscall for ia32.
Made better interrupt routines for ia32.
Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32.
Aligned interrupt handlers on ia32,amd64, this should prevent problems
with different instruction lengths.
 
1090 6636 d 15 h palkovsky /kernel/trunk/generic/ Reduced unnecessary IPC system calls.
Allow everything to be sync & async, everything is handled using messages.
