4055 5558 d 8 h trochtova /branches/dd/ changes in trunk (rev 4054) merged into dd branch  
3022 5841 d 10 h decky /branches/dd/ device drivers branch  
2784 5911 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 6035 d 1 h jermar /trunk/ Support for six syscall arguments for ia32.  
2071 6339 d 0 h jermar /trunk/ (c) versus (C)  
1787 6529 d 2 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1288 6596 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 6599 d 2 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1212 6609 d 3 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1100 6642 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 6647 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 6647 d 6 h jermar /kernel/trunk/arch/ia32/src/ Improved ia32 interrupt handlers.  
1008 6647 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 6649 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 6649 d 5 h jermar /kernel/trunk/ Support for loading segments containing .bss section.  
717 6706 d 2 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time
 
576 6742 d 20 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 6748 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6748 d 1 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6760 d 6 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
392 6808 d 1 h bondari /SPARTAN/trunk/arch/ia32/ Last inline functions for IA-32  
390 6808 d 23 h bondari /SPARTAN/trunk/arch/ia32/ ia-32 memcmp inline  
381 6813 d 22 h jermar /SPARTAN/trunk/ Make cross-compiler the default compiler on IA-32.
For native compilations, use ./build.ia32 native.

Small changes elsewhere.
 
358 6824 d 23 h bondari /SPARTAN/trunk/ built-in memcpy is not used anymore on IA-32.
IA-32 memcpy is now fast and inline.
 
357 6825 d 1 h bondari /SPARTAN/trunk/arch/ia32/src/ small fix  
356 6825 d 1 h bondari /SPARTAN/trunk/arch/ia32/ Get from port functions are now inline  
353 6825 d 11 h bondari /SPARTAN/trunk/arch/ia32/ Outb, outw, outl are now inline functions  
352 6825 d 23 h bondari /SPARTAN/trunk/arch/ia32/ outb inline function  
323 6834 d 9 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 6836 d 12 h jermar /SPARTAN/trunk/arch/ia32/src/ Optimize assembler code according to the knoweledge of IA-32 ABI.  
205 6843 d 11 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 6843 d 23 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

Cleanup.
 
196 6844 d 1 h vana /SPARTAN/trunk/arch/ia32/src/ ASM version of memcopy repaired on ia32  
185 6844 d 9 h decky /SPARTAN/trunk/arch/ OpenFirmware support  
168 6853 d 23 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 6884 d 8 h vana /SPARTAN/trunk/arch/ia32/src/ Typing error fixed  
141 6884 d 8 h vana /SPARTAN/trunk/ Clear IOPL on start of system on all CPUs and clear NT before all irets.  
137 6885 d 6 h vana /SPARTAN/trunk/arch/ia32/src/ Comments  
136 6885 d 6 h vana /SPARTAN/trunk/ Error word support debuging and testing passed with #NM & #GP exceptions.  
132 6885 d 9 h vana /SPARTAN/trunk/arch/ia32/ Added support for error-word generating exceptions in return routine.
