897 6662 d 4 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.
 
895 6662 d 8 h jermar /kernel/trunk/ sparc64 work.
Very raw and fragile preliminary standalone keyboard support - polling mode only.
Because of a workaround in Simics, the scan codes are the same as on ia32.
 
894 6662 d 11 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
860 6669 d 4 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy
 
832 6679 d 6 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6679 d 12 h jermar /kernel/trunk/ Make use of one unused bit in PTE formats of amd64, ia32 and mips32 to store 1 in valid mappings.
This helps to distinguish valid entries from not present entries with 0 content (i.e. not present
entries with PFN 0 and other bits cleared).
 
827 6680 d 5 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
825 6680 d 11 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 6681 d 5 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 6681 d 6 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 6681 d 16 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
809 6682 d 13 h palkovsky /kernel/trunk/arch/amd64/src/smp/ Simics GS patch even in SMP.  
808 6682 d 19 h palkovsky /kernel/trunk/arch/amd64/ Doc updates.  
807 6682 d 19 h palkovsky /kernel/trunk/arch/amd64/src/boot/ I'm unsure if simics is broken or the only one according to spec,
but SYSCALL now works even with simics.
 
806 6683 d 2 h palkovsky /kernel/trunk/arch/amd64/ Added (finally!) userspace to AMD64.
It does not work on Simics *$U&%&$&*#. Broken simics!!!
There should be probably LEA instead of MOV/ADD, but LEA does not
work in neither qemu nor bochs. Any other simulator to test? :-/
 
803 6683 d 4 h palkovsky /kernel/trunk/arch/amd64/ Basic amd syscall support.  
802 6683 d 6 h palkovsky /kernel/trunk/arch/amd64/ Userspace now starts executing correctly.  
800 6683 d 7 h palkovsky /kernel/trunk/arch/amd64/include/ Split AMD interrupt.h from ia32 version.  
799 6683 d 7 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
798 6683 d 7 h decky /kernel/trunk/arch/amd64/src/boot/ fix init_addr virtual address  
793 6683 d 13 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 6685 d 9 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.
 
769 6687 d 2 h palkovsky /kernel/trunk/ SLAB allocator now uses itself for all its internal structures.
Added description of allocator.
Removed messy_stack_trace from amd64, as it would scroll away important
part of exception.
 
765 6687 d 7 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6687 d 13 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.
 
760 6687 d 15 h jermar /kernel/trunk/ mips32 is not supposed to allocate page table.
This is done by the generic code now.
Remove PTL0 pointer as it is not needed.

Remove GET_PTL0_ADDRESS from kernel.

Update sparc64 comments in barrier.h.
 
756 6689 d 4 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 6690 d 4 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 6701 d 6 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
 
717 6705 d 10 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time
 
703 6707 d 15 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().
 
702 6707 d 16 h jermar /kernel/trunk/arch/amd64/src/ Fix amd64 interrupt_handler to properly remove error code from stack before iretq.  
696 6712 d 9 h decky /kernel/trunk/arch/amd64/ AMD64 SMP boots again  
695 6712 d 9 h decky /kernel/trunk/arch/amd64/ make AMD64 boot again (using grub, see /boot tree), SMP is still broken  
694 6712 d 10 h decky /kernel/trunk/arch/amd64/ break AMD64, will be fixed soon  
691 6712 d 12 h jermar /kernel/trunk/arch/ Cleanup.  
690 6712 d 12 h bondari /kernel/trunk/arch/ Fixes of 3-param frame_alloc() function calls  
687 6712 d 12 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.
 
685 6712 d 13 h decky /kernel/trunk/arch/amd64/ AMD64 PM initialization  
684 6712 d 13 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.
