1039 6652 d 12 h decky /kernel/trunk/arch/ update for the use of more init tasks  
1037 6652 d 12 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
1024 6653 d 5 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1021 6653 d 6 h jermar /kernel/trunk/ Hopefully final version of interrupt handlers for amd64 and ia32.
amd64 has been especially tricky to debug.
Error code detection is now done in compile time.		  
1004 6653 d 23 h decky /kernel/trunk/ ppc32: basic exception and interrupt handling  
984 6654 d 8 h palkovsky /kernel/trunk/arch/ Fixed invlpg for ia32 & amd64.  
977 6654 d 10 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6654 d 13 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
959 6655 d 3 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.		  
958 6655 d 4 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.		  
955 6655 d 4 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
940 6656 d 5 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6656 d 6 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
910 6663 d 11 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
906 6666 d 0 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 6669 d 0 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 6669 d 3 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 6669 d 7 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
860 6676 d 0 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
832 6686 d 1 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6686 d 8 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 6687 d 1 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
825 6687 d 7 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 6688 d 1 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 6688 d 2 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 6688 d 11 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
809 6689 d 9 h palkovsky /kernel/trunk/arch/amd64/src/smp/ Simics GS patch even in SMP.  
808 6689 d 14 h palkovsky /kernel/trunk/arch/amd64/ Doc updates.  
807 6689 d 15 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 6689 d 22 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 6690 d 0 h palkovsky /kernel/trunk/arch/amd64/ Basic amd syscall support.  
802 6690 d 2 h palkovsky /kernel/trunk/arch/amd64/ Userspace now starts executing correctly.  
800 6690 d 3 h palkovsky /kernel/trunk/arch/amd64/include/ Split AMD interrupt.h from ia32 version.  
799 6690 d 3 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
798 6690 d 3 h decky /kernel/trunk/arch/amd64/src/boot/ fix init_addr virtual address  
793 6690 d 9 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 6692 d 5 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.		  
769 6693 d 22 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 6694 d 3 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6694 d 9 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.
