1100 6662 d 0 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.
 
1078 6665 d 2 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.
 
1077 6665 d 6 h palkovsky /kernel/trunk/ Modified debugger to be able to coexist in AS watch mode and SMP.  
1074 6665 d 8 h palkovsky /kernel/trunk/ Ported AMD64 debugger to ia32 and enabled AS watchpoint to ia32 as well.  
1070 6665 d 10 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1066 6665 d 18 h jermar /kernel/trunk/ Support for user space threads.  
1059 6666 d 0 h jermar /kernel/trunk/ Clear user address space when creating new page tables.
Fix mapping of l_apic and io_apic on amd64.
 
1037 6666 d 8 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)
 
1024 6667 d 1 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.
 
1021 6667 d 2 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.
 
1019 6667 d 4 h vana /kernel/trunk/arch/ia32/ ia32 MMX and SSEx support  
1016 6667 d 5 h jermar /kernel/trunk/arch/ia32/src/ Improved ia32 interrupt handlers.  
1008 6667 d 8 h jermar /kernel/trunk/ Fix bug in ia32 interrupt handlers.
Handlers for interrupts greater than 31 wrapped the shift around and thus failed to correctly identify
the need to emulate error word.
 
984 6668 d 4 h palkovsky /kernel/trunk/arch/ Fixed invlpg for ia32 & amd64.  
977 6668 d 6 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6668 d 9 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
959 6668 d 23 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.
 
958 6669 d 0 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.
 
957 6669 d 0 h decky /kernel/trunk/arch/ run ppc32 kernel above 2 GB  
955 6669 d 0 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
952 6669 d 4 h jermar /kernel/trunk/ Support for loading segments containing .bss section.  
940 6670 d 1 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.
 
938 6670 d 2 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
925 6670 d 10 h palkovsky /kernel/trunk/arch/ia32/src/mm/ Fix e820list on ia32.  
910 6677 d 7 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
906 6679 d 20 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 6682 d 20 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 6683 d 3 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
893 6683 d 8 h jermar /kernel/trunk/arch/ sparc64 work.
Revive OFW console code and use it before the kernel switches to standalone console.

ia32 + ia64 cosmetic changes.
 
878 6685 d 6 h vana /kernel/trunk/ Active keyboard read for ia32  
860 6689 d 20 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy
 
854 6691 d 2 h bondari /kernel/trunk/ ELF loading workaround: some core declarations.  
832 6699 d 21 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6700 d 4 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 6700 d 21 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
825 6701 d 3 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 6701 d 20 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.
 
822 6701 d 21 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 6701 d 22 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 6702 d 7 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
