585 6785 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 6785 d 4 h palkovsky /kernel/trunk/generic/ Added calling of generic functions to kconsole.  
581 6785 d 7 h palkovsky /kernel/trunk/ Small debug changes.  
578 6785 d 17 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....
 
575 6785 d 19 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 6786 d 19 h jermar /kernel/trunk/generic/include/ Missing braces.
By the way, new ALIGN_UP broke ppc32 (commits 564 vs. 565).
 
569 6786 d 21 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.
 
565 6787 d 20 h jermar /kernel/trunk/generic/include/ Improved ALIGN_UP.  
564 6787 d 20 h jermar /kernel/trunk/ Send in some improvements.  
561 6788 d 2 h decky /kernel/trunk/ better way of placing revision, timestamp and arch in banner  
557 6788 d 6 h jermar /kernel/trunk/ Add comments describing locking rules for some locks.
Cleanup.
 
553 6788 d 21 h palkovsky /kernel/trunk/generic/include/synch/ Fix of compiling without SMP.  
552 6788 d 21 h palkovsky /kernel/trunk/ Named spinlocks  
548 6789 d 0 h jermar /kernel/trunk/ Cleanup and fixes.  
539 6790 d 0 h jermar /kernel/trunk/ Buddy allocator cleanup and fixes.
- Add some comments.
- Update zone information on frames allocation/deallocation.
 
538 6790 d 1 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 6790 d 2 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 6791 d 0 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6791 d 0 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 6791 d 0 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
524 6796 d 5 h jermar /kernel/trunk/generic/include/ sort.h was actually written by Sergey Bondari.  
518 6798 d 21 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 6799 d 20 h jermar /kernel/trunk/ Implement basic kernel console command recognition.
Commands without arguments are now recognized.
 
511 6802 d 19 h jermar /kernel/trunk/ Enable dummy kconsole for ia32 and amd64 (UP mode works).  
510 6802 d 20 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 6803 d 3 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 6803 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6803 d 21 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 6810 d 3 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 6811 d 0 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 6812 d 0 h jermar /SPARTAN/trunk/generic/include/ Fix typo in buddy.h.
Make default memsize 8M.
 
480 6812 d 23 h bondari /SPARTAN/trunk/generic/ Buddy system allocator implementation. Not checked. For review only.  
479 6814 d 1 h bondari /SPARTAN/trunk/generic/ Buddy system implementation. Not functional yet - only framework prepeared.
Also added 2 macros FRAME2ADDR and ADDR2FRAME.
 
475 6815 d 5 h jermar /SPARTAN/trunk/ Define atomic_t type.  
471 6816 d 5 h decky /SPARTAN/trunk/ remove NDEBUG, replace it by ~CONFIG_DEBUG
set CONFIG_DEBUG = y
 
458 6817 d 7 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
452 6817 d 23 h decky /SPARTAN/trunk/ major build system revision (unfinished)
this patchset most definitively breaks a lot of things, be patient
 
440 6819 d 2 h jermar /SPARTAN/trunk/generic/include/mm/ Add some comments for buddy system operations.  
430 6823 d 21 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
414 6838 d 10 h jermar /SPARTAN/trunk/ Create generic context_save() and context_restore().
These two functions are defined inline and only call context_save_arch() and context_restore_arch(), respectively.
The main purpose of this is to enable centralized commenting of these important and tricky functions.
