684 6738 d 23 h jermar /kernel/trunk/ Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface.
 
683 6738 d 23 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.
 
681 6739 d 2 h jermar /kernel/trunk/ Minor changes.  
678 6742 d 17 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
676 6742 d 20 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
673 6743 d 16 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.
 
669 6747 d 15 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().
 
664 6752 d 13 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.
 
662 6754 d 15 h decky /kernel/trunk/ initial syscall table support  
651 6758 d 14 h decky /kernel/trunk/ remove arch/$ARCH/boot where not needed, change global Makefile accordingly
remove early_mapping() (breaks ppc32 for now)
change early heap initialization (required for init to work)
 
650 6758 d 15 h jermar /kernel/trunk/ sparc64 work.
Implement interrupt_disable(), interrupt_enable(), interrupt_restore() and interrupt_read() functions.
Fix context save/restore to save/restore register %i7.
 
631 6762 d 17 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
629 6762 d 19 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6762 d 20 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6762 d 22 h palkovsky /kernel/trunk/ We are now almost -Wall clean.
- redefined atomic_t
- deleted many, many unused variables
- some minor code cleanups found using compiler warning.
 
624 6762 d 23 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6763 d 4 h jermar /kernel/trunk/ Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros.
SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations
in dynamically allocated structures on which spinlock_initialize() is called after
their creation.
SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations
of global spinlocks. It declares and initializes the spinlock.
Moreover, both macros are empty on UP so that -Wall warnings about unused structures
get supressed.
 
622 6763 d 18 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
615 6765 d 3 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
609 6765 d 21 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
607 6765 d 22 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.
 
601 6766 d 18 h palkovsky /kernel/trunk/ Added some readline functionality to kconsole.
Arrows editing, history, tab completion.
 
597 6767 d 1 h jermar /kernel/trunk/ Finer grained TLB invalidate functions for ia32 and amd64. Not yet deployed.  
596 6767 d 14 h jermar /kernel/trunk/ kconsole cleanup.
Separate commands from the engine.
 
594 6767 d 19 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
587 6767 d 22 h jermar /kernel/trunk/ Nasty hack for ppc32.
Main Makefile now passes -D$(ARCH) so that it is possible to have ugly architectural #ifdefs.
 
586 6767 d 22 h jermar /kernel/trunk/ Fix ppc32 and sparc64 to compile again.
Fix sparc64 to function again.
 
585 6767 d 22 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 6767 d 23 h palkovsky /kernel/trunk/generic/ Added calling of generic functions to kconsole.  
581 6768 d 2 h palkovsky /kernel/trunk/ Small debug changes.  
578 6768 d 12 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....
 
575 6768 d 14 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.
 
571 6769 d 13 h jermar /kernel/trunk/generic/include/ Missing braces.
By the way, new ALIGN_UP broke ppc32 (commits 564 vs. 565).
 
569 6769 d 15 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.
 
565 6770 d 14 h jermar /kernel/trunk/generic/include/ Improved ALIGN_UP.  
564 6770 d 15 h jermar /kernel/trunk/ Send in some improvements.  
561 6770 d 21 h decky /kernel/trunk/ better way of placing revision, timestamp and arch in banner  
557 6771 d 1 h jermar /kernel/trunk/ Add comments describing locking rules for some locks.
Cleanup.
 
553 6771 d 16 h palkovsky /kernel/trunk/generic/include/synch/ Fix of compiling without SMP.  
552 6771 d 16 h palkovsky /kernel/trunk/ Named spinlocks
