1609 6585 d 13 h decky /kernel/trunk/arch/ppc32/ generalize ppc32 exception handling  
1595 6585 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 6586 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 6589 d 12 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1480 6590 d 16 h palkovsky /kernel/trunk/arch/ppc32/ Added ability to process external interrupts to ppc.  
1475 6591 d 4 h jermar /kernel/trunk/arch/ Fix ppc32 and ppc64 to compile again.  
1423 6595 d 13 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1398 6601 d 6 h decky /kernel/trunk/arch/ port ppc32 changes to ppc64 (raw)  
1388 6601 d 8 h bondari /kernel/trunk/arch/ppc32/include/mm/  
1378 6603 d 13 h decky /kernel/trunk/arch/ppc32/ kernel identity mapping still to be done using BAT  
1374 6604 d 3 h decky /kernel/trunk/arch/ppc32/ ppc32 work
update framebuffer
get rid of the BAT memory mapping (not finished yet)		  
1371 6604 d 5 h decky /kernel/trunk/ unify the framebuffer API
use physical address as the base address for the framebuffer		  
1370 6604 d 7 h decky /kernel/trunk/arch/ppc32/ ppc32: update boot API  
1327 6608 d 12 h decky /kernel/trunk/ split framebuffer initialization and sysinfo registration  
1298 6615 d 11 h vana /kernel/trunk/ FB endian fix  
1288 6617 d 15 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.		  
1283 6620 d 4 h decky /kernel/trunk/arch/ppc32/include/ fix nasty CR clobber bug
change coding style		  
1277 6620 d 11 h decky /kernel/trunk/arch/ppc32/ ppc32 work:
(hopefully) final exception entry and exit rewrite
don't use FPU instructions in the kernel
syscall support		  
1270 6621 d 6 h decky /kernel/trunk/arch/ppc32/ page index and VSID fixes  
1269 6621 d 7 h decky /kernel/trunk/ PHT Refill handler  
1268 6621 d 12 h decky /kernel/trunk/arch/ppc32/ minor changes  
1267 6621 d 12 h decky /kernel/trunk/arch/ppc32/ ppc32: proper exception handling from user-space
code cleanup		  
1265 6621 d 13 h jermar /kernel/trunk/arch/ Add dummy IRQ_COUNT and irq_ipc_bind_arch() to ia64, ppc32 and sparc64 so that they compile again.  
1223 6629 d 14 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().		  
1222 6630 d 3 h decky /kernel/trunk/arch/ init tasks must be registered before main_bsp()  
1220 6630 d 4 h decky /kernel/trunk/arch/ppc32/ ppc32: initial userspace support  
1215 6630 d 7 h decky /kernel/trunk/arch/ ppc32: stub for Page Hash Table support  
1185 6639 d 12 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1184 6639 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 6640 d 18 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.		  
1163 6643 d 10 h decky /kernel/trunk/arch/ fix types  
1145 6650 d 12 h decky /kernel/trunk/arch/ppc32/ align ppc32 framebuffer on 128K boundary  
1132 6659 d 7 h decky /kernel/trunk/arch/ppc32/ kernel boot API change  
1107 6661 d 4 h jermar /kernel/trunk/ Small atomic #include and typedef changes.  
1104 6661 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.		  
1070 6666 d 17 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1067 6667 d 1 h decky /kernel/trunk/arch/ppc32/include/boot/ respect two more reserved frames  
1057 6667 d 8 h decky /kernel/trunk/arch/ppc32/ update kernel/loader API  
1024 6668 d 8 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1007 6668 d 14 h decky /kernel/trunk/ ppc32: preemptive scheduling works now
FPU context saving disabled for now
