1769 6528 d 5 h jermar /kernel/trunk/arch/ Change cache_error exception to take istate * as a parameter.
Make cache_error() print epc in the panic message.
Do not rely on the compiler to generate 'nop' after 'beq' in atomic_add()
and put it there explicitly.
Indentation fixes and cosmetic changes.
 
1731 6542 d 2 h jermar /kernel/trunk/ Updates in Doxygen-style comments.
Make architecture specific modules appear conditionally in the documentation.
Add time management module.
Improve names of other modules and sort module order
to be more like in the design documentation.
 
1705 6545 d 15 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.
 
1702 6546 d 12 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1686 6549 d 15 h decky /kernel/trunk/ update mips32 boot loading API  
1595 6553 d 19 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 6554 d 9 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 6557 d 12 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1474 6559 d 4 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1434 6562 d 8 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.
 
1423 6563 d 13 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1293 6585 d 11 h palkovsky /kernel/trunk/ Implemented mips memcpy (copy from gcc builtin memcpy).  
1288 6585 d 14 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 6591 d 4 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 6597 d 14 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().
 
1222 6598 d 3 h decky /kernel/trunk/arch/ init tasks must be registered before main_bsp()  
1185 6607 d 12 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1184 6607 d 12 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 6608 d 17 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.
 
1122 6628 d 2 h palkovsky /kernel/trunk/arch/mips32/ Set up T9 to entry point on entry to userspace to facilitate better
PIC running.
 
1107 6629 d 4 h jermar /kernel/trunk/ Small atomic #include and typedef changes.  
1104 6629 d 9 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 6630 d 4 h palkovsky /kernel/trunk/arch/ Keep $K1 register for use as a thread local storage pointer on MIPS.  
1100 6631 d 6 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 6631 d 13 h palkovsky /kernel/trunk/ Cleanup of mips
- inline register reads
- better fpu disable/enable - global settings is automatically propagated to task
- fast syscall
 
1087 6632 d 16 h palkovsky /kernel/trunk/arch/mips32/include/mm/ Fix MIPS32 bad paging index computation. Fixed random page faults on mips.  
1078 6634 d 8 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.
 
1070 6634 d 16 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1055 6635 d 9 h cejka /kernel/trunk/arch/mips32/include/ Stack constants moved to stack.h as on other archs.  
1054 6635 d 9 h cejka /kernel/trunk/ Updated stackarg macros for mips32.
Mips32 stack aligned on 8 bytes boundary.
 
1024 6636 d 7 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.
 
980 6637 d 12 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.
 
977 6637 d 12 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6637 d 16 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
958 6638 d 6 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 6638 d 7 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
941 6639 d 7 h palkovsky /kernel/trunk/ Fixed mips elf loading.  
940 6639 d 7 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.
 
938 6639 d 8 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
924 6639 d 18 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.
