3890 5571 d 14 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3274 5759 d 19 h jermar /trunk/ memcpy(), memmove() and similar functions return dst instead of src.
Fix all implementations, including those in assembly. ppc32 assembly
version didn't seem to be affected by this.
 
3044 5828 d 13 h jermar /trunk/kernel/arch/amd64/ Some inline functions in memstr.h seem to be of uncertain origin (amd64).
Replace either with built-in functions or with generic functions.
 
2784 5903 d 13 h jermar /trunk/kernel/arch/ Fortify ia32 and amd64 kernels against mallicious uspace applications that set
DF prior to entering the kernel. For AMD64 syscalls, we don't use the CLD
instruction, but make use of the SFMASK MSR instead. Simics works fine with
it, but QEMU seems to have a problem.
 
2606 6027 d 18 h jermar /trunk/ Support for 6 syscalls arguments on amd64.  
2071 6330 d 13 h jermar /trunk/ (c) versus (C)  
2018 6367 d 16 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
1787 6520 d 16 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1288 6587 d 22 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.
 
1278 6590 d 16 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1212 6600 d 16 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1121 6630 d 13 h jermar /kernel/trunk/ Small textual changes.  
1094 6633 d 23 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1021 6638 d 16 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.
 
955 6640 d 14 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
820 6673 d 12 h jermar /kernel/trunk/ Convert size_t, count_t and index_t to 64-bits on 64-bit architectures.
Change some pfn_t usages to count_t, size_t and index_t.
 
808 6675 d 0 h palkovsky /kernel/trunk/arch/amd64/ Doc updates.  
806 6675 d 8 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 6675 d 10 h palkovsky /kernel/trunk/arch/amd64/ Basic amd syscall support.  
799 6675 d 13 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
717 6697 d 15 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time
 
702 6699 d 22 h jermar /kernel/trunk/arch/amd64/src/ Fix amd64 interrupt_handler to properly remove error code from stack before iretq.  
576 6734 d 9 h palkovsky /kernel/trunk/ Changed ia32 & amd64 to use exc_register instead of trap_register.

Fixed dependency list building. I hope you all have 'makedepend' installed,
if you don't it's time to install it, as CC -M builds the dependency
list without directory names..and it just does not work.
 
534 6739 d 14 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6739 d 15 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6751 d 19 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
472 6764 d 20 h jermar /SPARTAN/trunk/ Changes in build system.
For .S targets, always do -D__ASM__.
Remove unnecessary #define __ASM__ from various *.S files.
At the end of build, generate disassembler dump for kernel.raw.

ia64 work.
Better General Exception handler.
 
348 6821 d 13 h jermar /SPARTAN/trunk/arch/ Optimize some assembler functions.  
332 6823 d 21 h palkovsky /SPARTAN/trunk/ Updated symtab so that it works correctly with BE architectures.
Changed compiler for BE MIPS to be mips-sgi-irix5, because
mipsel -EB does not behave correctly.
Doc updates to amd64.
Added ARC BIOS support to MIPS architecture. Putchar works correctly,
kernel passed FPU & some rwlock tests.
 
257 6832 d 0 h palkovsky /SPARTAN/trunk/ Added basic FPU context (not working).
Added CPU utilities from ia32
Fixed bug in vm.c that wanted PTL to be mapped in bottom memory.
 
252 6832 d 3 h palkovsky /SPARTAN/trunk/arch/amd64/ Added volatile to inb/outb, so that it does not optimeze
lot of things out anymore.
Working delay loop.
 
251 6832 d 10 h palkovsky /SPARTAN/trunk/ Changes, that were needed to make it work on Bochs.
- We CAN use the NX bit in paging tables, but we have
to initialize the NXE bit in EFER register first.
 
242 6832 d 20 h palkovsky /SPARTAN/trunk/ Fixed stack settings in boot.S in real mode.
Added ia32 memmap support.
Added cpuid support.
 
224 6834 d 0 h palkovsky /SPARTAN/trunk/arch/ Interrupts for amd64.
