1769 6701 d 5 h jermar /kernel/trunk/arch/ Change cache_error exception to take istate * as a parameter.
Make cache_error() print epc in the panic message.
Do not rely on the compiler to generate 'nop' after 'beq' in atomic_add()
and put it there explicitly.
Indentation fixes and cosmetic changes.		  
1754 6712 d 15 h jermar /kernel/trunk/ Indentation and some improved comments.
Remove forgotten comment from gxemul.sh.		  
1702 6719 d 12 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1595 6726 d 19 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.		  
1221 6771 d 3 h decky /kernel/trunk/ printf-related and other code cleanup  
1196 6777 d 13 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1126 6800 d 14 h palkovsky /kernel/trunk/arch/mips32/src/ Fix bad order of EPC & STATUS change in syscall_shortcut.  
1119 6801 d 5 h palkovsky /kernel/trunk/arch/ Fixed bad rflags masking in amd64.
Added TLS get address instruction emulation for mips.		  
1100 6804 d 6 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.		  
1096 6804 d 13 h palkovsky /kernel/trunk/ Cleanup of mips
- inline register reads
- better fpu disable/enable - global settings is automatically propagated to task
- fast syscall		  
959 6811 d 5 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.		  
958 6811 d 6 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.		  
955 6811 d 7 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
852 6834 d 12 h palkovsky /kernel/trunk/ Fixes in memory allocator
- proper kernel blacklisting, when kernel not loaded on page boundary
- correct zone adding in zone list (how could this work??)		  
799 6846 d 5 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
794 6846 d 10 h palkovsky /kernel/trunk/ Added MIPS userspace. Currently can't make it work in gxemul.  
615 6901 d 15 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
614 6902 d 1 h palkovsky /kernel/trunk/ Added support for mips breakpoints.
We have a kind of kernel debugger :-)
Breakpoints on JMP/Branch instructions are not supported and
they are reported after the breakpoint is fired and exited as
a BranchDelay exception. If we found a way, how to detect these
instructions, we would be able to support them as 'one-time' breakpoints.		  
610 6902 d 9 h palkovsky /kernel/trunk/arch/mips32/ Cleanup of unnecessary things.  
609 6902 d 9 h palkovsky /kernel/trunk/ added support for breakpoints to mips32
