806 6702 d 23 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 6703 d 1 h palkovsky /kernel/trunk/arch/amd64/ Basic amd syscall support.  
802 6703 d 3 h palkovsky /kernel/trunk/arch/amd64/ Userspace now starts executing correctly.  
799 6703 d 4 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
798 6703 d 4 h decky /kernel/trunk/arch/amd64/src/boot/ fix init_addr virtual address  
793 6703 d 10 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 6706 d 23 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 6709 d 1 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 6710 d 0 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 6725 d 6 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time
 
703 6727 d 12 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 6727 d 13 h jermar /kernel/trunk/arch/amd64/src/ Fix amd64 interrupt_handler to properly remove error code from stack before iretq.  
696 6732 d 6 h decky /kernel/trunk/arch/amd64/ AMD64 SMP boots again  
695 6732 d 6 h decky /kernel/trunk/arch/amd64/ make AMD64 boot again (using grub, see /boot tree), SMP is still broken  
694 6732 d 7 h decky /kernel/trunk/arch/amd64/ break AMD64, will be fixed soon  
691 6732 d 8 h jermar /kernel/trunk/arch/ Cleanup.  
690 6732 d 8 h bondari /kernel/trunk/arch/ Fixes of 3-param frame_alloc() function calls  
687 6732 d 9 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.
 
685 6732 d 10 h decky /kernel/trunk/arch/amd64/ AMD64 PM initialization  
684 6732 d 10 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 6736 d 2 h decky /kernel/trunk/arch/ remove deprecated pre-grub stuff on ia32
prepare for the same on amd64
 
674 6736 d 13 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
625 6756 d 9 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.
 
576 6762 d 0 h palkovsky /kernel/trunk/ Changed ia32 & amd64 to use exc_register instead of trap_register.

Fixed dependency list building. I hope you all have 'makedepend' installed,
if you don't it's time to install it, as CC -M builds the dependency
list without directory names..and it just does not work.
 
566 6764 d 1 h palkovsky /kernel/trunk/ Fixed bug in Intel32/AMD64 boot, that could cause page fault on boot.
Fixes of configuration program.
 
548 6765 d 5 h jermar /kernel/trunk/ Cleanup and fixes.  
540 6766 d 2 h jermar /kernel/trunk/arch/ Map all available frames of memory on ia32 and amd64 (ticket #10).  
534 6767 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6767 d 5 h bondari /SPARTAN/trunk/ Buddy allocator for physical memory complete implementation.
Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed.
NOTE: Other architectures could be broken (but should not be)
 
532 6767 d 6 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
512 6778 d 12 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.
 
511 6779 d 1 h jermar /kernel/trunk/ Enable dummy kconsole for ia32 and amd64 (UP mode works).  
503 6779 d 9 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 6779 d 10 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6780 d 3 h jermar /SPARTAN/trunk/ Rename map_page_to_frame() to page_mapping_insert() and find_mapping() to page_mapping_find().
New names should make it more apparent that these two belong together.
 
472 6792 d 11 h jermar /SPARTAN/trunk/ Changes in build system.
For .S targets, always do -D__ASM__.
Remove unnecessary #define __ASM__ from various *.S files.
At the end of build, generate disassembler dump for kernel.raw.

ia64 work.
Better General Exception handler.
 
467 6793 d 8 h jermar /SPARTAN/trunk/arch/ Add sparc64 context_offset.h.
Fix symbolic links in amd64 to be relative.
 
458 6793 d 13 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
457 6793 d 13 h decky /SPARTAN/trunk/ new build system almost finished  
452 6794 d 5 h decky /SPARTAN/trunk/ major build system revision (unfinished)
this patchset most definitively breaks a lot of things, be patient
