4055 5725 d 5 h trochtova /branches/dd/ changes in trunk (rev 4054) merged into dd branch  
3022 6008 d 8 h decky /branches/dd/ device drivers branch  
2784 6078 d 21 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 6203 d 2 h jermar /trunk/ Support for 6 syscalls arguments on amd64.  
2071 6505 d 22 h jermar /trunk/ (c) versus (C)  
2018 6543 d 1 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
1787 6696 d 0 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1288 6763 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 6766 d 0 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1212 6776 d 0 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1121 6805 d 21 h jermar /kernel/trunk/ Small textual changes.  
1094 6809 d 8 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1021 6814 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 6815 d 23 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
820 6848 d 20 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 6850 d 9 h palkovsky /kernel/trunk/arch/amd64/ Doc updates.  
806 6850 d 16 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 6850 d 19 h palkovsky /kernel/trunk/arch/amd64/ Basic amd syscall support.  
799 6850 d 21 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
717 6873 d 0 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time
