1377 6606 d 19 h jermar /kernel/trunk/arch/sparc64/include/drivers/ Remove unneeded macro.  
1288 6620 d 20 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.		  
1265 6624 d 19 h jermar /kernel/trunk/arch/ Add dummy IRQ_COUNT and irq_ipc_bind_arch() to ia64, ppc32 and sparc64 so that they compile again.

1184 6642 d 18 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.

Change the encapsulated counter type to long so that it supports negative values as well.		  
1082 6669 d 12 h jermar /kernel/trunk/arch/sparc64/include/ Fix atomic_postdec() operation.  
1070 6669 d 22 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1024 6671 d 13 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
977 6672 d 18 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6672 d 22 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
958 6673 d 12 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 6673 d 13 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
940 6674 d 13 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6674 d 14 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
910 6681 d 19 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
901 6685 d 21 h jermar /kernel/trunk/arch/ ia64 work.
Provide PA2KA(identity) mapping for kernel data references via Alternate Data TLB Fault handler.
Add before_thread_runs_arch() that maps kstack, if necessary.
Add easy to use dtlb_mapping_insert() for comfortable insertion of kernel data mappings.		  
897 6687 d 8 h jermar /kernel/trunk/ sparc64 work.
Fix KBD_VIRT_ADDRESS.
Call before_thread_runs() prior to the switch to the thread's stack. Add comment why this is crucial.
Add after_thread_ran() to the scheduler.
Add before_thread_runs_arch() and after_thread_ran_arch() for sparc64, mapping/demapping thread's kernel stack.
Add dummy after_thread_ran_arch() to all other architectures.
Add dtlb_insert_mapping() to promote code reuse.		  
895 6687 d 12 h jermar /kernel/trunk/ sparc64 work.
Very raw and fragile preliminary standalone keyboard support - polling mode only.
Because of a workaround in Simics, the scan codes are the same as on ia32.		  
894 6687 d 15 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
893 6687 d 20 h jermar /kernel/trunk/arch/ sparc64 work.
Revive OFW console code and use it before the kernel switches to standalone console.

ia32 + ia64 cosmetic changes.		  
889 6688 d 19 h jermar /kernel/trunk/arch/sparc64/include/drivers/ Forgotten fb.h for sparc64.  
883 6688 d 20 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Switch console to framebuffer (needs proper detection and initialization).
No native keyboard support, so far.
Memory management trap handler fixes.
Do not use OpenFirmware trap table anymore.		  
877 6690 d 12 h jermar /kernel/trunk/arch/sparc64/ Fixes in sparc64 preliminary TLB miss handler.
Compute and insert identity mapping for kernel on the fly.		  
873 6690 d 20 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add more MMU helper functions and make data TLB miss handler more verbose.		  
867 6692 d 17 h jermar /kernel/trunk/ Move OFW functionality of ppc32 memory_init to genarch so that the code can also be used by sparc64.
sparc64 is now close to broken as it lacks functionality to provide identity mapping for the whole phyisical memory.		  
864 6693 d 9 h jermar /kernel/trunk/arch/sparc64/include/trap/ Add forgotten file.  
863 6693 d 9 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.

Fix ppc32 to at least compile.		  
792 6708 d 18 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.		  
765 6712 d 11 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6712 d 17 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
760 6712 d 20 h jermar /kernel/trunk/ mips32 is not supposed to allocate page table.
This is done by the generic code now.
Remove PTL0 pointer as it is not needed.

Remove GET_PTL0_ADDRESS from kernel.

Update sparc64 comments in barrier.h.		  
758 6713 d 9 h jermar /kernel/trunk/arch/ sparc64 bugfix.
When disabling IMMU and DMMU the kernel has to perform synchronization operation
(e.g flush %r or membar #Sync instruction). There is no guarantee that the address
contained in %r is in DTLB and therefore the flush instruction can fault. Normally
this would be recognized and fixed by the OpenFirmware Fast Data MMU fault handler.
However, this handler lives in virtually mapped memory and an attempt to execute
there while the MMUs are disabled would result in a nested trap leading to error state.
Replacing flush %r instruction with membar #Sync, wich is sufficient in this case,
fixes this problem.
