759 6685 d 14 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.  
757 6685 d 19 h jermar /kernel/trunk/ Blacklist addresses between 0xa0000 and 0xfffff on ia64 for frame allocator.
This area contains VGA text frame buffer and should be avoided.
falloc2 test now passes on ia64.
 
756 6686 d 16 h jermar /kernel/trunk/ Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.
 
755 6687 d 16 h jermar /kernel/trunk/ Change page_mapping_find/insert interfaces to take as_t * as first argument
and not asid_t as second argument. This change was necessitated by the
removal of mapping array from as_area_t and the fact that an address
space doesn't have an ASID when it is created.
 
727 6698 d 18 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
 
724 6700 d 19 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
703 6705 d 3 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().
 
684 6710 d 1 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 6714 d 3 h jermar /kernel/trunk/generic/src/ Clean up.  
673 6714 d 18 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.
 
671 6715 d 19 h vana /kernel/trunk/ i8042 bug fix...  
651 6729 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 6731 d 17 h jermar /kernel/trunk/ sparc64 work.
CPU identification.
 
628 6733 d 22 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6734 d 0 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 6734 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 6735 d 1 h palkovsky /kernel/trunk/ better architecture line  
578 6739 d 14 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....
 
564 6741 d 17 h jermar /kernel/trunk/ Send in some improvements.  
562 6741 d 23 h decky /kernel/trunk/generic/src/main/ fix typo  
561 6741 d 23 h decky /kernel/trunk/ better way of placing revision, timestamp and arch in banner  
534 6744 d 21 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6744 d 21 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
523 6751 d 0 h jermar /kernel/trunk/ Clean up.  
518 6752 d 17 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 6753 d 17 h jermar /kernel/trunk/ Implement basic kernel console command recognition.
Commands without arguments are now recognized.
 
512 6756 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 6756 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 6756 d 22 h decky /kernel/trunk/ preparation for init task loading  
503 6757 d 0 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 6757 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
470 6770 d 15 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 6771 d 2 h decky /SPARTAN/trunk/ even fancier release/revision display  
462 6771 d 2 h decky /SPARTAN/trunk/ include svn revision and build time in the kernel  
460 6771 d 3 h decky /SPARTAN/trunk/ some fancy stuff  
458 6771 d 4 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
430 6777 d 18 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
414 6792 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 6792 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 6800 d 5 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.
