684 6722 d 2 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.
 
675 6726 d 4 h jermar /kernel/trunk/generic/src/ Clean up.  
673 6726 d 19 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.
 
671 6727 d 20 h vana /kernel/trunk/ i8042 bug fix...  
651 6741 d 16 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)
 
640 6743 d 18 h jermar /kernel/trunk/ sparc64 work.
CPU identification.
 
628 6745 d 23 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6746 d 1 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.
 
623 6746 d 6 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.
 
621 6747 d 2 h palkovsky /kernel/trunk/ better architecture line  
578 6751 d 15 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....
 
564 6753 d 18 h jermar /kernel/trunk/ Send in some improvements.  
562 6754 d 0 h decky /kernel/trunk/generic/src/main/ fix typo  
561 6754 d 0 h decky /kernel/trunk/ better way of placing revision, timestamp and arch in banner  
534 6756 d 21 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6756 d 21 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
523 6763 d 1 h jermar /kernel/trunk/ Clean up.  
518 6764 d 18 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 6765 d 18 h jermar /kernel/trunk/ Implement basic kernel console command recognition.
Commands without arguments are now recognized.
 
512 6768 d 3 h jermar /kernel/trunk/ SMP work.
Add madt_irq_to_pin().
Make ksmp() use virtual irq_to_pin() function, which makes better sence for ACPI configurations.
 
510 6768 d 17 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.
 
506 6768 d 22 h decky /kernel/trunk/ preparation for init task loading  
503 6769 d 1 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 6769 d 2 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
470 6782 d 16 h jermar /SPARTAN/trunk/ ia64 work.
Big cleanup of IA-64 interrupt processing.
Merge of interrupt.c and interrupt_handler.c.
Rewrite of ivt.S and interrupt.c.
Higher level interrupt handlers are now passed a vector number and a pointer to stack structure.

ia32 work.
ia32 has ordered writes. Until it deploys weaker memory ordering model, write_barrier() can be empty statement.
 
463 6783 d 2 h decky /SPARTAN/trunk/ even fancier release/revision display  
462 6783 d 3 h decky /SPARTAN/trunk/ include svn revision and build time in the kernel  
460 6783 d 4 h decky /SPARTAN/trunk/ some fancy stuff  
458 6783 d 5 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
430 6789 d 19 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
414 6804 d 7 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.
 
413 6804 d 17 h jermar /SPARTAN/trunk/ Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority.
 
402 6812 d 6 h jermar /SPARTAN/trunk/ Add ALIGN() macro.

Fix usage of early_mapping() in main.c.
The previous version would not map part of the heap.
Please, review.
 
389 6818 d 6 h jermar /SPARTAN/trunk/ MIPS work.
Fix some name inconsistencies between cp0 functions' declarations and definitions.
Add and implement tlb_init_arch().
Add tlb_modified() exception handler.

Other architectures: add dummy tlb_init_arch().
 
374 6828 d 18 h jermar /SPARTAN/trunk/ Revert previous change in frame_t as it broke IA-64.
(Most likely some alignment problem.)

Rename heap_init(), malloc() and free(), respectively, to early_heap_init(), early_malloc() and early_free(), respectively.
Define new macros malloc() and free(). They are to be replaced by real functions some day.
 
373 6828 d 20 h jermar /SPARTAN/trunk/ Physical memory management work.
Add "__attribute__ ((packed))" to frame_t so that it takes up less space.
Note that this is essential as there is lot of these structures.
Remove busy list from zone_t as it is redundant.
 
369 6830 d 22 h jermar /SPARTAN/trunk/src/main/ The more physical frames, the more memory allocated for heap.  
298 6847 d 5 h decky /SPARTAN/trunk/ remove lower 2 GB identity mapping (IA-32)  
242 6850 d 3 h palkovsky /SPARTAN/trunk/ Fixed stack settings in boot.S in real mode.
Added ia32 memmap support.
Added cpuid support.
 
238 6850 d 23 h vana /SPARTAN/trunk/ Register dump on IA-64 exceptions
