594 6773 d 4 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
587 6773 d 7 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 6773 d 7 h jermar /kernel/trunk/ Fix ppc32 and sparc64 to compile again.
Fix sparc64 to function again.
 
585 6773 d 7 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 6773 d 8 h palkovsky /kernel/trunk/generic/ Added calling of generic functions to kconsole.  
581 6773 d 11 h palkovsky /kernel/trunk/ Small debug changes.  
578 6773 d 21 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....
 
575 6773 d 23 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 6774 d 22 h jermar /kernel/trunk/generic/include/ Missing braces.
By the way, new ALIGN_UP broke ppc32 (commits 564 vs. 565).
 
569 6775 d 0 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.
 
565 6775 d 23 h jermar /kernel/trunk/generic/include/ Improved ALIGN_UP.  
564 6776 d 0 h jermar /kernel/trunk/ Send in some improvements.  
561 6776 d 6 h decky /kernel/trunk/ better way of placing revision, timestamp and arch in banner  
557 6776 d 9 h jermar /kernel/trunk/ Add comments describing locking rules for some locks.
Cleanup.
 
553 6777 d 1 h palkovsky /kernel/trunk/generic/include/synch/ Fix of compiling without SMP.  
552 6777 d 1 h palkovsky /kernel/trunk/ Named spinlocks  
548 6777 d 3 h jermar /kernel/trunk/ Cleanup and fixes.  
539 6778 d 4 h jermar /kernel/trunk/ Buddy allocator cleanup and fixes.
- Add some comments.
- Update zone information on frames allocation/deallocation.
 
538 6778 d 5 h jermar /kernel/trunk/ Buddy allocator cleanup and fixes II.
- Rewrite IS_BUDDY_LEFT_BLOCK so that it does not need floating point on some architectures (e.g. IA-64).
- Get rid of IS_BUDDY_RIGHT_BLOCK.
- Make sparc64 use zone_create_in_region.
 
537 6778 d 6 h jermar /kernel/trunk/ Buddy system cleanup and fixes.
- missing use of KA2PA in frame_init
- truncating black list addresses to frame boundaries
- removal of left-over obsolete structures
- fixing some comments
 
534 6779 d 3 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6779 d 3 h bondari /SPARTAN/trunk/ Buddy allocator for physical memory complete implementation.
Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed.
NOTE: Other architectures could be broken (but should not be)
 
532 6779 d 4 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
524 6784 d 9 h jermar /kernel/trunk/generic/include/ sort.h was actually written by Sergey Bondari.  
518 6787 d 0 h jermar /kernel/trunk/ Improve kconsole's support for recognition of commands with arguments.
Implement ARG_TYPE_STRING.
Add 'describe' command.
Move kconsole.c to generic/src/console.
Move kconsole.h to generic/include/console.
 
517 6788 d 0 h jermar /kernel/trunk/ Implement basic kernel console command recognition.
Commands without arguments are now recognized.
 
511 6790 d 23 h jermar /kernel/trunk/ Enable dummy kconsole for ia32 and amd64 (UP mode works).  
510 6790 d 23 h jermar /kernel/trunk/ Add chardev_t.
This type is meant to abstract any input character device such as keyboard, serial port etc.
Add stdin.
Add dummy kconsole.
 
503 6791 d 7 h jermar /kernel/trunk/ Rename arch_late_init() to arch_pre_smp_init().
Add arch_post_smp_init().
Enable IRQ_KBD on ia-32 (doesn't work on Bochs SMP, works on Bochs UP).
 
501 6791 d 8 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6792 d 1 h jermar /SPARTAN/trunk/ Rename map_page_to_frame() to page_mapping_insert() and find_mapping() to page_mapping_find().
New names should make it more apparent that these two belong together.
 
489 6798 d 7 h jermar /SPARTAN/trunk/generic/ Make the buddy system more general.
Store implementation defined pointer in buddy_system_t.
Pass buddy system pointer to implementation defined buddy system operations.
 
483 6799 d 3 h jermar /SPARTAN/trunk/ For now, each architecture must use its own -O switch (-O2 doesn't work for ia64, -O3 doesn't work for mips32).

New mips32 atomic_add() function.

Cleanup.
 
482 6800 d 4 h jermar /SPARTAN/trunk/generic/include/ Fix typo in buddy.h.
Make default memsize 8M.
 
480 6801 d 2 h bondari /SPARTAN/trunk/generic/ Buddy system allocator implementation. Not checked. For review only.  
479 6802 d 4 h bondari /SPARTAN/trunk/generic/ Buddy system implementation. Not functional yet - only framework prepeared.
Also added 2 macros FRAME2ADDR and ADDR2FRAME.
 
475 6803 d 9 h jermar /SPARTAN/trunk/ Define atomic_t type.  
471 6804 d 9 h decky /SPARTAN/trunk/ remove NDEBUG, replace it by ~CONFIG_DEBUG
set CONFIG_DEBUG = y
 
458 6805 d 11 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
452 6806 d 3 h decky /SPARTAN/trunk/ major build system revision (unfinished)
this patchset most definitively breaks a lot of things, be patient
