4343 5603 d 0 h svoboda /branches/dynload/ Merged trunk changes up to r3925 to dynload.  
3674 5747 d 23 h svoboda /branches/dynload/ Merge latest trunk changes to dynload.  
3535 5782 d 4 h svoboda /branches/dynload/ Merge latest trunk changes into dynload.  
3403 5830 d 10 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3107 5930 d 12 h svoboda /branches/dynload/ Merge trunk changes up to r3044 into dynload  
2927 5952 d 11 h decky /branches/dynload/ added dynload branch  
2784 6009 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.
 
2613 6132 d 1 h jermar /trunk/ Support for six syscall arguments for ia32.  
2071 6436 d 0 h jermar /trunk/ (c) versus (C)  
1787 6626 d 3 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1288 6693 d 9 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 6696 d 3 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1212 6706 d 3 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1100 6739 d 0 h palkovsky /kernel/trunk/ Cleanup of spinlocks, now compiles both ia32 and amd64 with
and without DEBUG_SPINLOCKS. Made spinlocks inline.
Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32).
Made slightly faster syscall for ia32.
Made better interrupt routines for ia32.
Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32.
Aligned interrupt handlers on ia32,amd64, this should prevent problems
with different instruction lengths.
 
1021 6744 d 3 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.
 
1016 6744 d 6 h jermar /kernel/trunk/arch/ia32/src/ Improved ia32 interrupt handlers.  
1008 6744 d 8 h jermar /kernel/trunk/ Fix bug in ia32 interrupt handlers.
Handlers for interrupts greater than 31 wrapped the shift around and thus failed to correctly identify
the need to emulate error word.
 
958 6746 d 1 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.
 
952 6746 d 5 h jermar /kernel/trunk/ Support for loading segments containing .bss section.  
717 6803 d 2 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time
