614 6767 d 17 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.
 
611 6768 d 0 h jermar /kernel/trunk/generic/src/console/ Fix kconsole so that side-effect command shortcuts do not take effect.  
609 6768 d 1 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
608 6768 d 2 h palkovsky /kernel/trunk/generic/src/console/ intelligent retyping for set4  
607 6768 d 2 h palkovsky /kernel/trunk/ Fixed weird simics panic.
Run kconsole, if we panic. This currently works in gxemul,
simics. In mips we need to modify the simulator.
On ia32 we need a function, that would speak directly to the chip
and fetch the character using polling.
 
606 6768 d 3 h palkovsky /kernel/trunk/ Small kconsole readline changes.
Some mips tweaks to allow for real keyboard support in indy.
 
603 6768 d 20 h palkovsky /kernel/trunk/generic/src/ Added set4 command.  
602 6768 d 21 h palkovsky /kernel/trunk/ Symtab returns correct addresses even when symtab is befor bss.
Some tab completion optimization.
 
601 6768 d 23 h palkovsky /kernel/trunk/ Added some readline functionality to kconsole.
Arrows editing, history, tab completion.
 
596 6769 d 19 h jermar /kernel/trunk/ kconsole cleanup.
Separate commands from the engine.
 
594 6770 d 0 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
591 6770 d 1 h palkovsky /kernel/trunk/generic/src/ Fixes in new console.  
589 6770 d 2 h palkovsky /kernel/trunk/generic/src/console/ Added * operator to symbols.  
588 6770 d 2 h palkovsky /kernel/trunk/ Added support for backspace
- printing '\b' should move the cursor one char to the left
- backspace key should return '\b' to application
 
585 6770 d 3 h palkovsky /kernel/trunk/generic/ String constants without spaces are now supported by call commands.
For more we would need some lexer.
The call? commands are not compatibile with stdarg functions on AMD
architectures, because of the calling sequence.
 
582 6770 d 4 h palkovsky /kernel/trunk/generic/ Added calling of generic functions to kconsole.  
579 6770 d 7 h palkovsky /kernel/trunk/generic/src/ Removed unnecessary interrupts_disable from kconsole.
Fixed calling gets() with interrupts_disable.
 
575 6770 d 18 h palkovsky /kernel/trunk/ Added generic exc_register/exc_dispatch functions,
copied from ia32 architecture. Currently only mips32 uses them.

The chardev_t can now be both input & output device (was
needed for serial driver).

Broken other architectures - ia64, sparc, powerpc will not compile.

Mips32 supports input on all msim, gxemul, indy(tested emulation
in gxemul, loses characters), simics. Simics serial line
is done using polling, I was unable to make it produce
an interrupt when the key was pressed.
 
552 6773 d 21 h palkovsky /kernel/trunk/ Named spinlocks  
548 6773 d 23 h jermar /kernel/trunk/ Cleanup and fixes.
