4055 5585 d 12 h trochtova /branches/dd/ changes in trunk (rev 4054) merged into dd branch  
3022 5868 d 14 h decky /branches/dd/ device drivers branch  
2784 5939 d 4 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 6063 d 9 h jermar /trunk/ Support for 6 syscalls arguments on amd64.  
2071 6366 d 4 h jermar /trunk/ (c) versus (C)  
2018 6403 d 7 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
1787 6556 d 6 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1288 6623 d 13 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 6626 d 6 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1212 6636 d 7 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1121 6666 d 4 h jermar /kernel/trunk/ Small textual changes.  
1094 6669 d 14 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1021 6674 d 7 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 6676 d 5 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
820 6709 d 2 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 6710 d 15 h palkovsky /kernel/trunk/arch/amd64/ Doc updates.  
806 6710 d 22 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 6711 d 1 h palkovsky /kernel/trunk/arch/amd64/ Basic amd syscall support.  
799 6711 d 4 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
717 6733 d 6 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time
