3403 5779 d 17 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3107 5879 d 19 h svoboda /branches/dynload/ Merge trunk changes up to r3044 into dynload  
2927 5901 d 18 h decky /branches/dynload/ added dynload branch  
2784 5958 d 6 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 6081 d 8 h jermar /trunk/ Support for six syscall arguments for ia32.  
2071 6385 d 7 h jermar /trunk/ (c) versus (C)  
1787 6575 d 9 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1288 6642 d 16 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 6645 d 9 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1212 6655 d 10 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1100 6688 d 7 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 6693 d 10 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 6693 d 13 h jermar /kernel/trunk/arch/ia32/src/ Improved ia32 interrupt handlers.  
1008 6693 d 15 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 6695 d 8 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 6695 d 12 h jermar /kernel/trunk/ Support for loading segments containing .bss section.  
717 6752 d 9 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time
 
576 6789 d 3 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.
 
534 6794 d 8 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6794 d 8 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6806 d 13 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
392 6854 d 8 h bondari /SPARTAN/trunk/arch/ia32/ Last inline functions for IA-32  
390 6855 d 6 h bondari /SPARTAN/trunk/arch/ia32/ ia-32 memcmp inline  
381 6860 d 5 h jermar /SPARTAN/trunk/ Make cross-compiler the default compiler on IA-32.
For native compilations, use ./build.ia32 native.

Small changes elsewhere.
 
358 6871 d 6 h bondari /SPARTAN/trunk/ built-in memcpy is not used anymore on IA-32.
IA-32 memcpy is now fast and inline.
 
357 6871 d 8 h bondari /SPARTAN/trunk/arch/ia32/src/ small fix  
356 6871 d 8 h bondari /SPARTAN/trunk/arch/ia32/ Get from port functions are now inline  
353 6871 d 18 h bondari /SPARTAN/trunk/arch/ia32/ Outb, outw, outl are now inline functions  
352 6872 d 6 h bondari /SPARTAN/trunk/arch/ia32/ outb inline function  
323 6880 d 16 h jermar /SPARTAN/trunk/ Add comments for new floating point modifiers to print.c.
Remove left-over comments from AMD64 and IA-32 page.c.
Coding style clean up.
 
316 6882 d 19 h jermar /SPARTAN/trunk/arch/ia32/src/ Optimize assembler code according to the knoweledge of IA-32 ABI.  
205 6889 d 18 h jermar /SPARTAN/trunk/ Get rid of memcopy().
All we now have is memcpy() and _memcpy().
memcpy() is defined to be builtin.
Where not applicable, architectures must implement memcpy() code or call slowish _memcopy().
 
198 6890 d 6 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

Cleanup.
 
196 6890 d 8 h vana /SPARTAN/trunk/arch/ia32/src/ ASM version of memcopy repaired on ia32  
185 6890 d 16 h decky /SPARTAN/trunk/arch/ OpenFirmware support  
168 6900 d 6 h jermar /SPARTAN/trunk/ Add type cast to __address in vm_create().
This seems to fix the problem with userspace.
Looks like KA2PA() returned wrong address when applied on pte_t *.

Uncomment panic() in gp_fault().
Get rid of cli and sti in userspace code.
 
142 6930 d 15 h vana /SPARTAN/trunk/arch/ia32/src/ Typing error fixed  
141 6930 d 15 h vana /SPARTAN/trunk/ Clear IOPL on start of system on all CPUs and clear NT before all irets.  
137 6931 d 13 h vana /SPARTAN/trunk/arch/ia32/src/ Comments  
136 6931 d 13 h vana /SPARTAN/trunk/ Error word support debuging and testing passed with #NM & #GP exceptions.
