1100 6668 d 9 h palkovsky /kernel/trunk/ Cleanup of spinlocks, now compiles both ia32 and amd64 with
and without DEBUG_SPINLOCKS. Made spinlocks inline.
Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32).
Made slightly faster syscall for ia32.
Made better interrupt routines for ia32.
Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32.
Aligned interrupt handlers on ia32,amd64, this should prevent problems
with different instruction lengths.
 
1094 6668 d 19 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1078 6671 d 12 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.
 
1077 6671 d 16 h palkovsky /kernel/trunk/ Modified debugger to be able to coexist in AS watch mode and SMP.  
1074 6671 d 18 h palkovsky /kernel/trunk/ Ported AMD64 debugger to ia32 and enabled AS watchpoint to ia32 as well.

Did small changes to IPC infrastructure.
 
1066 6672 d 4 h jermar /kernel/trunk/ Support for user space threads.  
1064 6672 d 5 h palkovsky /kernel/trunk/arch/amd64/ Cleanup of amd64 code.  
1063 6672 d 6 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1060 6672 d 9 h palkovsky /kernel/trunk/ Added task_print.
Fixed ipc to support connect_me_to.
 
1052 6672 d 13 h decky /kernel/trunk/arch/amd64/src/boot/ fix wrong structure members size assumption  
1051 6672 d 13 h jermar /kernel/trunk/arch/amd64/ Move amd64's ident_page_mapper() and page_fault() to page.h.  
1050 6672 d 14 h palkovsky /kernel/trunk/ Added null console for buffering output when no real output available.
Added identity mapper for AMD64 that allows whole physical memory to be
accessed before paging is initialized.
 
1039 6672 d 18 h decky /kernel/trunk/arch/ update for the use of more init tasks  
1037 6672 d 18 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)
 
1021 6673 d 12 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 6674 d 5 h decky /kernel/trunk/ ppc32: basic exception and interrupt handling  
959 6675 d 9 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.
 
958 6675 d 10 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 6675 d 10 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
938 6676 d 11 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
906 6686 d 6 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 6689 d 6 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.
 
894 6689 d 13 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
827 6707 d 6 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
825 6707 d 13 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 6708 d 7 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 6708 d 7 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 6708 d 17 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
809 6709 d 14 h palkovsky /kernel/trunk/arch/amd64/src/smp/ Simics GS patch even in SMP.  
808 6709 d 20 h palkovsky /kernel/trunk/arch/amd64/ Doc updates.  
807 6709 d 20 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 6710 d 3 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 6710 d 6 h palkovsky /kernel/trunk/arch/amd64/ Basic amd syscall support.  
802 6710 d 7 h palkovsky /kernel/trunk/arch/amd64/ Userspace now starts executing correctly.  
799 6710 d 9 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
798 6710 d 9 h decky /kernel/trunk/arch/amd64/src/boot/ fix init_addr virtual address  
793 6710 d 15 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 6714 d 3 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 6716 d 6 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.
