4343 6092 d 21 h svoboda /branches/dynload/ Merged trunk changes up to r3925 to dynload.  
3674 6237 d 20 h svoboda /branches/dynload/ Merge latest trunk changes to dynload.  
3535 6272 d 1 h svoboda /branches/dynload/ Merge latest trunk changes into dynload.  
3403 6320 d 8 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3107 6420 d 10 h svoboda /branches/dynload/ Merge trunk changes up to r3044 into dynload  
2927 6442 d 9 h decky /branches/dynload/ added dynload branch  
2784 6498 d 21 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 6621 d 23 h jermar /trunk/ Support for six syscall arguments for ia32.  
2071 6925 d 22 h jermar /trunk/ (c) versus (C)  
1787 7116 d 0 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1288 7183 d 7 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 7186 d 0 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1212 7196 d 1 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1100 7228 d 22 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 7234 d 1 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 7234 d 4 h jermar /kernel/trunk/arch/ia32/src/ Improved ia32 interrupt handlers.  
1008 7234 d 6 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 7235 d 22 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 7236 d 2 h jermar /kernel/trunk/ Support for loading segments containing .bss section.  
717 7293 d 0 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time
 
576 7329 d 18 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 7334 d 23 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 7334 d 23 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 7347 d 3 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
392 7394 d 23 h bondari /SPARTAN/trunk/arch/ia32/ Last inline functions for IA-32  
390 7395 d 20 h bondari /SPARTAN/trunk/arch/ia32/ ia-32 memcmp inline  
381 7400 d 20 h jermar /SPARTAN/trunk/ Make cross-compiler the default compiler on IA-32.
For native compilations, use ./build.ia32 native.

Small changes elsewhere.
 
358 7411 d 21 h bondari /SPARTAN/trunk/ built-in memcpy is not used anymore on IA-32.
IA-32 memcpy is now fast and inline.
 
357 7411 d 22 h bondari /SPARTAN/trunk/arch/ia32/src/ small fix  
356 7411 d 23 h bondari /SPARTAN/trunk/arch/ia32/ Get from port functions are now inline  
353 7412 d 9 h bondari /SPARTAN/trunk/arch/ia32/ Outb, outw, outl are now inline functions  
352 7412 d 21 h bondari /SPARTAN/trunk/arch/ia32/ outb inline function  
323 7421 d 7 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 7423 d 10 h jermar /SPARTAN/trunk/arch/ia32/src/ Optimize assembler code according to the knoweledge of IA-32 ABI.  
205 7430 d 9 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 7430 d 21 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

Cleanup.
 
196 7430 d 22 h vana /SPARTAN/trunk/arch/ia32/src/ ASM version of memcopy repaired on ia32  
185 7431 d 7 h decky /SPARTAN/trunk/arch/ OpenFirmware support  
168 7440 d 21 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 7471 d 5 h vana /SPARTAN/trunk/arch/ia32/src/ Typing error fixed
