1256 6616 d 21 h jermar /kernel/trunk/arch/ Improve SYS_IOSPACE_ENABLE support.
The general protection fault handler now contains
code to service early I/O Permission bitmap faults.
 
1251 6617 d 22 h jermar /kernel/trunk/ Fix BITS2BYTES macro to return 0 when passed 0 as argument.
Fix ia32 TSS segment granularity to be 0.
Fix ia32 and amd64 initial TSS limit to be 103.
Little textual changes here and there.
 
1212 6623 d 18 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1203 6628 d 20 h jermar /kernel/trunk/arch/ Full implementation of amd64 and ia32 SYS_ENABLE_IOSPACE syscall.
Needs testing.
 
1201 6628 d 20 h jermar /kernel/trunk/arch/ Fix amd64 and ia32 management of I/O bitmap in before_task_runs_arch()
by treating the iomap array as a bitmap. Make use of the bitmap type
and functions added in previous commit.
 
1187 6632 d 19 h jermar /kernel/trunk/ Cleanup pm.c and pm.h code on ia32 and amd64.
Add before_task_runs() and before_task_runs_arch() for each architecture.
Add ia32 and amd64 code to ensure I/O Permission Bitmap update.
 
1186 6632 d 20 h jermar /kernel/trunk/arch/ Replace assembly from pm.c with new inline functions defined in asm.h.  
1184 6632 d 22 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.
 
1121 6653 d 15 h jermar /kernel/trunk/ Small textual changes.  
1112 6654 d 2 h palkovsky /kernel/trunk/ Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).
 
1104 6654 d 19 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.
 
1100 6656 d 16 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.
 
1077 6659 d 23 h palkovsky /kernel/trunk/ Modified debugger to be able to coexist in AS watch mode and SMP.  
1072 6660 d 0 h palkovsky /kernel/trunk/ Added debugger to AMD64.
Added automatic debugging of AS if it is not rewritten with zero.
Did small changes to IPC infrastructure.
 
1070 6660 d 2 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1064 6660 d 11 h palkovsky /kernel/trunk/arch/amd64/ Cleanup of amd64 code.  
1063 6660 d 12 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1051 6660 d 20 h jermar /kernel/trunk/arch/amd64/ Move amd64's ident_page_mapper() and page_fault() to page.h.  
1050 6660 d 20 h palkovsky /kernel/trunk/ Added null console for buffering output when no real output available.
Added identity mapper for AMD64 that allows whole physical memory to be
accessed before paging is initialized.
 
1024 6661 d 17 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.
 
1021 6661 d 18 h jermar /kernel/trunk/ Hopefully final version of interrupt handlers for amd64 and ia32.
amd64 has been especially tricky to debug.
Error code detection is now done in compile time.
 
984 6662 d 20 h palkovsky /kernel/trunk/arch/ Fixed invlpg for ia32 & amd64.  
977 6662 d 22 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6663 d 1 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
959 6663 d 15 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.
 
958 6663 d 16 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 6663 d 16 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
940 6664 d 17 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.
 
938 6664 d 18 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
910 6671 d 23 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
895 6677 d 16 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 6677 d 19 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
860 6684 d 12 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy
 
832 6694 d 14 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6694 d 20 h jermar /kernel/trunk/ Make use of one unused bit in PTE formats of amd64, ia32 and mips32 to store 1 in valid mappings.
This helps to distinguish valid entries from not present entries with 0 content (i.e. not present
entries with PFN 0 and other bits cleared).
 
825 6695 d 19 h jermar /kernel/trunk/ Remove WAKEUP_IPI stuff.

Make it possible to use PAGE_GLOBAL on ia32, amd64 and mips32.
Make ia32 and amd64 map the kernel using PAGE_GLOBAL.
 
814 6697 d 0 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
808 6698 d 3 h palkovsky /kernel/trunk/arch/amd64/ Doc updates.  
806 6698 d 10 h palkovsky /kernel/trunk/arch/amd64/ Added (finally!) userspace to AMD64.
It does not work on Simics *$U&%&$&*#. Broken simics!!!
There should be probably LEA instead of MOV/ADD, but LEA does not
work in neither qemu nor bochs. Any other simulator to test? :-/
 
803 6698 d 12 h palkovsky /kernel/trunk/arch/amd64/ Basic amd syscall support.
