938 6695 d 12 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
925 6695 d 20 h palkovsky /kernel/trunk/arch/ia32/src/mm/ Fix e820list on ia32.  
906 6705 d 6 h palkovsky /kernel/trunk/ Added lazy fpu context allocation.
- threads that don't use fpu, don't get allocated fpu context
- fpu context alignment on AMD64 nicely disappeared		  
897 6708 d 6 h jermar /kernel/trunk/ sparc64 work.
Fix KBD_VIRT_ADDRESS.
Call before_thread_runs() prior to the switch to the thread's stack. Add comment why this is crucial.
Add after_thread_ran() to the scheduler.
Add before_thread_runs_arch() and after_thread_ran_arch() for sparc64, mapping/demapping thread's kernel stack.
Add dummy after_thread_ran_arch() to all other architectures.
Add dtlb_insert_mapping() to promote code reuse.		  
894 6708 d 13 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
893 6708 d 18 h jermar /kernel/trunk/arch/ sparc64 work.
Revive OFW console code and use it before the kernel switches to standalone console.

ia32 + ia64 cosmetic changes.		  
878 6710 d 16 h vana /kernel/trunk/ Active keyboard read for ia32  
827 6726 d 7 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
825 6726 d 13 h jermar /kernel/trunk/ Remove WAKEUP_IPI stuff.

Make it possible to use PAGE_GLOBAL on ia32, amd64 and mips32.
Make ia32 and amd64 map the kernel using PAGE_GLOBAL.		  
822 6727 d 7 h palkovsky /kernel/trunk/ Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.		  
820 6727 d 8 h jermar /kernel/trunk/ Convert size_t, count_t and index_t to 64-bits on 64-bit architectures.
Change some pfn_t usages to count_t, size_t and index_t.		  
814 6727 d 18 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
812 6728 d 8 h jermar /kernel/trunk/ Documentation and dot.bochsrc upgrade.  
793 6729 d 15 h jermar /kernel/trunk/ Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations.		  
778 6731 d 11 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.		  
756 6735 d 6 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 6736 d 6 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.		  
750 6737 d 10 h jermar /kernel/trunk/ ia32 SMP updates.
Update info about supported version of Bochs (bump the counter to 2.2.6).
Add Task Priority Register type and initialize this register to a known state.		  
730 6745 d 13 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
727 6747 d 8 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
717 6751 d 12 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
714 6751 d 13 h decky /kernel/trunk/ syscall handler return value
uspace task termination (primitive)		  
712 6751 d 14 h decky /kernel/trunk/ "Hello world" from user space :)  
703 6753 d 17 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().		  
693 6758 d 12 h decky /kernel/trunk/arch/ia32/ simplify and cleanup ia32 boot process, remove obsolete stuff  
690 6758 d 14 h bondari /kernel/trunk/arch/ Fixes of 3-param frame_alloc() function calls  
687 6758 d 14 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
684 6758 d 15 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.		  
682 6758 d 16 h decky /kernel/trunk/arch/ia32/src/mm/ fix ia32 build  
680 6762 d 8 h decky /kernel/trunk/arch/ remove deprecated pre-grub stuff on ia32
prepare for the same on amd64		  
674 6762 d 19 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
672 6764 d 8 h jermar /kernel/trunk/arch/ia32/ ia32 work.
Initialize LDR and DFR registers in Local APIC so that logical destination addresses work.		  
671 6764 d 9 h vana /kernel/trunk/ i8042 bug fix...  
670 6764 d 13 h vana /kernel/trunk/arch/ia32/src/drivers/ i8042 command word init... It should work on ia32 but I have done it for Indy and I'm not sure it will work because on Silicon should not be the same software in universal microprocesor i8042. So if It will not work I'll remove it and will write i8042 AT function emulation.  
629 6782 d 11 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6782 d 12 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6782 d 14 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 6782 d 20 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.		  
615 6784 d 19 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
606 6785 d 15 h palkovsky /kernel/trunk/ Small kconsole readline changes.
Some mips tweaks to allow for real keyboard support in indy.
