1024 6820 d 18 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1021 6820 d 19 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 6821 d 12 h decky /kernel/trunk/ ppc32: basic exception and interrupt handling  
984 6821 d 21 h palkovsky /kernel/trunk/arch/ Fixed invlpg for ia32 & amd64.  
977 6821 d 23 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6822 d 2 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
959 6822 d 16 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.		  
958 6822 d 17 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 6822 d 17 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
940 6823 d 18 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6823 d 18 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
910 6830 d 23 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
906 6833 d 12 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 6836 d 13 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 6836 d 16 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 6836 d 20 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
860 6843 d 13 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
832 6853 d 14 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6853 d 21 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 6854 d 13 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.
