794 6748 d 0 h palkovsky /kernel/trunk/ Added MIPS userspace. Currently can't make it work in gxemul.  
789 6748 d 18 h palkovsky /kernel/trunk/generic/ Early SLAB initialization, the cpu-cache is initialized later.
If you want to use slab_cache_create befor slab_cpu_enable, add
a flag SLAB_CACHE_MAGDEFERRED.
 
773 6750 d 14 h palkovsky /kernel/trunk/ Added slab stress test.
Fixed race condition in slab allocator.
Moved initialization of slab to the point where we know correct config.cpu_count
Correctly passes tests on amd64, ia32 in both bochs & qemu.
 
759 6752 d 14 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.  
757 6752 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 6753 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 6754 d 15 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.
 
754 6754 d 16 h jermar /kernel/trunk/generic/ Remove address space area mapping array.
The information is to be stored directly in page tables.
This is to better support 64-bit systems which can have
fairly large address space areas.
 
727 6765 d 17 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
 
724 6767 d 19 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
718 6769 d 18 h decky /kernel/trunk/ interface change: as_area_load_mapping -> as_area_set_mapping (set single page mapping)
map init directly from the physical frames it is loaded in
 
717 6769 d 21 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time
 
703 6772 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 6777 d 0 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 6781 d 2 h jermar /kernel/trunk/generic/src/ Clean up.  
673 6781 d 18 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.
 
671 6782 d 18 h vana /kernel/trunk/ i8042 bug fix...  
654 6795 d 22 h jermar /kernel/trunk/generic/src/ Fix page_insert_mapping().
Some architectures (e.g. ia32) need to have the lower-numbered PTL's flagged as PAGE_WRITE in order to prevent overriding protection bits of leaf TTE's.
 
651 6796 d 15 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 6798 d 16 h jermar /kernel/trunk/ sparc64 work.
CPU identification.
 
629 6800 d 20 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6800 d 21 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6800 d 23 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 6801 d 5 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 6802 d 0 h palkovsky /kernel/trunk/ better architecture line  
615 6803 d 4 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
609 6803 d 22 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
578 6806 d 13 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....
 
564 6808 d 17 h jermar /kernel/trunk/ Send in some improvements.  
562 6808 d 22 h decky /kernel/trunk/generic/src/main/ fix typo  
561 6808 d 22 h decky /kernel/trunk/ better way of placing revision, timestamp and arch in banner  
534 6811 d 20 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6811 d 20 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
523 6817 d 23 h jermar /kernel/trunk/ Clean up.  
518 6819 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 6820 d 17 h jermar /kernel/trunk/ Implement basic kernel console command recognition.
Commands without arguments are now recognized.
 
512 6823 d 2 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 6823 d 16 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.
 
508 6823 d 19 h jermar /kernel/trunk/ Basic keyboard support for ia32.
For some reason, keyoboard looks dead on SMP.

Make kinit() print "kinit..." strings in longer intervals.
 
506 6823 d 21 h decky /kernel/trunk/ preparation for init task loading
