1051 6649 d 12 h jermar /kernel/trunk/arch/amd64/ Move amd64's ident_page_mapper() and page_fault() to page.h.  
1050 6649 d 12 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 6649 d 16 h decky /kernel/trunk/arch/ update for the use of more init tasks  
1037 6649 d 17 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
1024 6650 d 9 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1021 6650 d 10 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 6651 d 3 h decky /kernel/trunk/ ppc32: basic exception and interrupt handling  
984 6651 d 12 h palkovsky /kernel/trunk/arch/ Fixed invlpg for ia32 & amd64.  
977 6651 d 14 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6651 d 17 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
959 6652 d 7 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.		  
958 6652 d 8 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 6652 d 8 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
940 6653 d 9 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6653 d 10 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
910 6660 d 15 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
906 6663 d 4 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 6666 d 4 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 6666 d 8 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 6666 d 11 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.
