803 6680 d 7 h palkovsky /kernel/trunk/arch/amd64/ Basic amd syscall support.  
802 6680 d 9 h palkovsky /kernel/trunk/arch/amd64/ Userspace now starts executing correctly.  
799 6680 d 10 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
798 6680 d 10 h decky /kernel/trunk/arch/amd64/src/boot/ fix init_addr virtual address  
793 6680 d 16 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.		  
769 6684 d 5 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.		  
756 6686 d 7 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 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.		  
717 6702 d 13 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
703 6704 d 18 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 6704 d 19 h jermar /kernel/trunk/arch/amd64/src/ Fix amd64 interrupt_handler to properly remove error code from stack before iretq.  
696 6709 d 12 h decky /kernel/trunk/arch/amd64/ AMD64 SMP boots again  
695 6709 d 12 h decky /kernel/trunk/arch/amd64/ make AMD64 boot again (using grub, see /boot tree), SMP is still broken  
694 6709 d 13 h decky /kernel/trunk/arch/amd64/ break AMD64, will be fixed soon  
691 6709 d 14 h jermar /kernel/trunk/arch/ Cleanup.  
690 6709 d 15 h bondari /kernel/trunk/arch/ Fixes of 3-param frame_alloc() function calls  
687 6709 d 15 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
685 6709 d 16 h decky /kernel/trunk/arch/amd64/ AMD64 PM initialization  
684 6709 d 16 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.		  
680 6713 d 8 h decky /kernel/trunk/arch/ remove deprecated pre-grub stuff on ia32
prepare for the same on amd64
