3274 5743 d 16 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 5812 d 11 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 5887 d 11 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 6011 d 15 h jermar /trunk/ Support for 6 syscalls arguments on amd64.  
2071 6314 d 11 h jermar /trunk/ (c) versus (C)  
2018 6351 d 14 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
1787 6504 d 13 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1288 6571 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.
 
1278 6574 d 13 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1212 6584 d 14 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1121 6614 d 10 h jermar /kernel/trunk/ Small textual changes.  
1094 6617 d 21 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1021 6622 d 14 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 6624 d 12 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
820 6657 d 9 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 6658 d 22 h palkovsky /kernel/trunk/arch/amd64/ Doc updates.  
806 6659 d 5 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 6659 d 8 h palkovsky /kernel/trunk/arch/amd64/ Basic amd syscall support.  
799 6659 d 11 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
717 6681 d 13 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time
