3890 6151 d 2 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3274 6339 d 7 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 6408 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 6483 d 1 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 6607 d 6 h jermar /trunk/ Support for 6 syscalls arguments on amd64.  
2071 6910 d 2 h jermar /trunk/ (c) versus (C)  
2018 6947 d 4 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
1787 7100 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1288 7167 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 7170 d 4 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1212 7180 d 4 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1121 7210 d 1 h jermar /kernel/trunk/ Small textual changes.  
1094 7213 d 11 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1021 7218 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 7220 d 2 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
820 7253 d 0 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 7254 d 13 h palkovsky /kernel/trunk/arch/amd64/ Doc updates.  
806 7254 d 20 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 7254 d 22 h palkovsky /kernel/trunk/arch/amd64/ Basic amd syscall support.  
799 7255 d 1 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.
