3890 6301 d 1 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3274 6489 d 6 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 6558 d 1 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 6633 d 0 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 6757 d 5 h jermar /trunk/ Support for 6 syscalls arguments on amd64.  
2071 7060 d 1 h jermar /trunk/ (c) versus (C)  
2018 7097 d 4 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
1787 7250 d 3 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1288 7317 d 10 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 7320 d 3 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1212 7330 d 4 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1121 7360 d 0 h jermar /kernel/trunk/ Small textual changes.  
1094 7363 d 11 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1021 7368 d 4 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 7370 d 2 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
820 7402 d 23 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 7404 d 12 h palkovsky /kernel/trunk/arch/amd64/ Doc updates.  
806 7404 d 19 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 7404 d 22 h palkovsky /kernel/trunk/arch/amd64/ Basic amd syscall support.  
799 7405 d 0 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.
