3890 5792 d 23 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3274 5981 d 4 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 6049 d 22 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 6124 d 22 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 6249 d 3 h jermar /trunk/ Support for 6 syscalls arguments on amd64.  
2071 6551 d 23 h jermar /trunk/ (c) versus (C)  
2018 6589 d 1 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
1787 6742 d 1 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1288 6809 d 7 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 6812 d 1 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1212 6822 d 1 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1121 6851 d 22 h jermar /kernel/trunk/ Small textual changes.  
1094 6855 d 8 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1021 6860 d 1 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 6861 d 23 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
820 6894 d 21 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 6896 d 10 h palkovsky /kernel/trunk/arch/amd64/ Doc updates.  
806 6896 d 17 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 6896 d 19 h palkovsky /kernel/trunk/arch/amd64/ Basic amd syscall support.  
799 6896 d 22 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.
