1595 6561 d 14 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.
 
1587 6562 d 4 h jermar /kernel/trunk/ task_destroy() implementation, fixes in as_destroy() and task_kill().
This is the first version of HelenOS that would perform complete cleanup leading from thread to destruction of address space.
 
1511 6565 d 7 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1474 6566 d 23 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1434 6570 d 3 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.
 
1423 6571 d 8 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1293 6593 d 6 h palkovsky /kernel/trunk/ Implemented mips memcpy (copy from gcc builtin memcpy).  
1288 6593 d 9 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.
 
1258 6598 d 23 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.
 
1223 6605 d 9 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().
 
1222 6605 d 22 h decky /kernel/trunk/arch/ init tasks must be registered before main_bsp()  
1185 6615 d 7 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1184 6615 d 7 h jermar /kernel/trunk/ Move arch/thread.h to arch/proc/thread.h on all architectures.
Replace ARCH_THREAD_DATA with new thread_arch_t arch on all architectures.
Similarily, add task_arch_t arch on all architectures.
On amd64 and ia32, grow the TSS segment by 64K + 1B to support IO port
permission bitmap. For the same reason, define per task IO port permission bitmaps
on ia32 and amd64.
 
1171 6616 d 12 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.
 
1122 6635 d 21 h palkovsky /kernel/trunk/arch/mips32/ Set up T9 to entry point on entry to userspace to facilitate better
PIC running.
 
1107 6636 d 23 h jermar /kernel/trunk/ Small atomic #include and typedef changes.  
1104 6637 d 4 h jermar /kernel/trunk/ Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.
 
1102 6637 d 23 h palkovsky /kernel/trunk/arch/ Keep $K1 register for use as a thread local storage pointer on MIPS.  
1100 6639 d 1 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.
 
1096 6639 d 8 h palkovsky /kernel/trunk/ Cleanup of mips
- inline register reads
- better fpu disable/enable - global settings is automatically propagated to task
- fast syscall
 
1087 6640 d 11 h palkovsky /kernel/trunk/arch/mips32/include/mm/ Fix MIPS32 bad paging index computation. Fixed random page faults on mips.  
1078 6642 d 3 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.
 
1070 6642 d 11 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1055 6643 d 4 h cejka /kernel/trunk/arch/mips32/include/ Stack constants moved to stack.h as on other archs.  
1054 6643 d 4 h cejka /kernel/trunk/ Updated stackarg macros for mips32.
Mips32 stack aligned on 8 bytes boundary.
 
1024 6644 d 2 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.
 
980 6645 d 7 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.
 
977 6645 d 7 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6645 d 11 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
958 6646 d 1 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.
 
955 6646 d 2 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
941 6647 d 2 h palkovsky /kernel/trunk/ Fixed mips elf loading.  
940 6647 d 2 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.
 
938 6647 d 3 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
924 6647 d 13 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
910 6654 d 8 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
906 6656 d 21 h palkovsky /kernel/trunk/ Added lazy fpu context allocation.
- threads that don't use fpu, don't get allocated fpu context
- fpu context alignment on AMD64 nicely disappeared
 
860 6666 d 21 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy
 
853 6669 d 6 h palkovsky /kernel/trunk/arch/mips32/ Some arc bios tweaks. Wanted to print configuration data, but
the ARC seems to return strange values.
Newport graphics card does not seem to be easy to port, give up now.
 
852 6669 d 7 h palkovsky /kernel/trunk/ Fixes in memory allocator
- proper kernel blacklisting, when kernel not loaded on page boundary
- correct zone adding in zone list (how could this work??)
