831 6677 d 2 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).
 
830 6677 d 4 h jermar /kernel/trunk/ Make ASID FIFO for mips32 be allocated statically.
Make ASID FIFO for sparc64 and ia64 be allocated dynamically.
Fix ia64 to call asid_fifo_init().
All three architectures now call asid_fifo_init() from as_arch_init().
 
827 6677 d 19 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
825 6678 d 2 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.
 
823 6678 d 19 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.
 
822 6678 d 20 h palkovsky /kernel/trunk/ Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.
 
821 6678 d 20 h jermar /kernel/trunk/arch/sparc64/src/mm/ Do not add CONFIG_STACK_SIZE to kernel.size.  
820 6678 d 20 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.
 
819 6678 d 22 h vana /kernel/trunk/arch/ia64/ TR tlb filling functions  
818 6679 d 1 h vana /kernel/trunk/arch/ia64/ IA-64 TLB filling functions for dynamic tlb filling (TC tlb).  
817 6679 d 4 h palkovsky /kernel/trunk/ Small cleanup.  
816 6679 d 5 h jermar /kernel/trunk/ Fix mapping1 test.

Cleanup.
 
815 6679 d 5 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.
 
814 6679 d 6 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
813 6679 d 18 h jermar /kernel/trunk/ Change ia64 kernel image to link and load at 0x100000 where
it (or its heap or stack) won't mess up with the ROM region.

Blacklist ia64 frame 0 from frame allocator so that 0 won't be
returned to malloc and friends. This can be reenabled again
once the kernel is not identity mapped.
 
812 6679 d 20 h jermar /kernel/trunk/ Documentation and dot.bochsrc upgrade.  
811 6679 d 22 h jermar /kernel/trunk/ Fix number of steps in softint division.
Make ia64 port compile with softint.
 
809 6680 d 3 h palkovsky /kernel/trunk/arch/amd64/src/smp/ Simics GS patch even in SMP.  
808 6680 d 9 h palkovsky /kernel/trunk/arch/amd64/ Doc updates.  
807 6680 d 9 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 6680 d 16 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 6680 d 19 h palkovsky /kernel/trunk/arch/amd64/ Basic amd syscall support.  
802 6680 d 20 h palkovsky /kernel/trunk/arch/amd64/ Userspace now starts executing correctly.  
800 6680 d 21 h palkovsky /kernel/trunk/arch/amd64/include/ Split AMD interrupt.h from ia32 version.  
799 6680 d 21 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
798 6680 d 22 h decky /kernel/trunk/arch/amd64/src/boot/ fix init_addr virtual address  
797 6681 d 1 h palkovsky /kernel/trunk/arch/mips32/ Fixed uspace address constants.  
796 6681 d 2 h palkovsky /kernel/trunk/ Gxemul support for mips userspace. MIPS now _must_ be started
always with userspace, there is (almost) no way how to pass parameters
to kernel.
 
794 6681 d 3 h palkovsky /kernel/trunk/ Added MIPS userspace. Currently can't make it work in gxemul.  
793 6681 d 3 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.
 
792 6681 d 4 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.
 
786 6682 d 2 h bondari /kernel/trunk/ frame_alloc() functions variations in order to avoid problems with frame_alloc_generic() changes.
IMPORTANT: Parameter order for frame_alloc() was changed
 
778 6683 d 0 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.
 
769 6684 d 16 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 6684 d 21 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
764 6685 d 2 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
763 6685 d 4 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.
 
762 6685 d 5 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference
 
760 6685 d 6 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.
 
758 6685 d 20 h jermar /kernel/trunk/arch/ sparc64 bugfix.
When disabling IMMU and DMMU the kernel has to perform synchronization operation
(e.g flush %r or membar #Sync instruction). There is no guarantee that the address
contained in %r is in DTLB and therefore the flush instruction can fault. Normally
this would be recognized and fixed by the OpenFirmware Fast Data MMU fault handler.
However, this handler lives in virtually mapped memory and an attempt to execute
there while the MMUs are disabled would result in a nested trap leading to error state.
Replacing flush %r instruction with membar #Sync, wich is sufficient in this case,
fixes this problem.
