3890 5793 d 0 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3631 5874 d 22 h jermar /trunk/kernel/arch/ia32/src/ The IA-32 manual is very secretive about the fact that the SYSENTER instruction
disables interrupts (I found only one evidence of this in the instruction's
pseudo code). The sysenter_handler needs to reenable the interrupts in order to
preserve the preemptive nature of the kernel.
 
3485 5924 d 22 h jermar /trunk/ Support for SYSENTER on ia32.  
3274 5981 d 4 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.
 
3043 6049 d 23 h jermar /trunk/kernel/arch/ia32/ Some inline functions in memstr.h seem to be of uncertain origin (ia32).
Replace either with built-in functions or with generic functions.
 
2784 6124 d 23 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 6248 d 0 h jermar /trunk/ Support for six syscall arguments for ia32.  
2071 6551 d 23 h jermar /trunk/ (c) versus (C)  
1787 6742 d 1 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1288 6809 d 8 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 6812 d 1 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1212 6822 d 2 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1100 6854 d 23 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 6860 d 2 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 6860 d 5 h jermar /kernel/trunk/arch/ia32/src/ Improved ia32 interrupt handlers.  
1008 6860 d 7 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 6862 d 0 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 6862 d 4 h jermar /kernel/trunk/ Support for loading segments containing .bss section.  
717 6919 d 1 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time
 
576 6955 d 19 h palkovsky /kernel/trunk/ Changed ia32 & amd64 to use exc_register instead of trap_register.

Fixed dependency list building. I hope you all have 'makedepend' installed,
if you don't it's time to install it, as CC -M builds the dependency
list without directory names..and it just does not work.
