973 6810 d 9 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
965 6810 d 12 h palkovsky /kernel/trunk/ Added skeleton name service.
Cleanup for IPC to use mutexes instead of spinlocks.
 
955 6811 d 1 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
938 6812 d 3 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
820 6843 d 23 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.
 
817 6844 d 7 h palkovsky /kernel/trunk/ Small cleanup.  
794 6846 d 5 h palkovsky /kernel/trunk/ Added MIPS userspace. Currently can't make it work in gxemul.  
756 6851 d 21 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.
 
754 6852 d 21 h jermar /kernel/trunk/generic/ Remove address space area mapping array.
The information is to be stored directly in page tables.
This is to better support 64-bit systems which can have
fairly large address space areas.
 
727 6863 d 23 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
 
718 6868 d 0 h decky /kernel/trunk/ interface change: as_area_load_mapping -> as_area_set_mapping (set single page mapping)
map init directly from the physical frames it is loaded in
 
717 6868 d 3 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time
 
703 6870 d 8 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().
 
673 6879 d 23 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.
 
654 6894 d 3 h jermar /kernel/trunk/generic/src/ Fix page_insert_mapping().
Some architectures (e.g. ia32) need to have the lower-numbered PTL's flagged as PAGE_WRITE in order to prevent overriding protection bits of leaf TTE's.
 
629 6899 d 2 h decky /kernel/trunk/ init task loading (yet buggy)  
625 6899 d 5 h palkovsky /kernel/trunk/ We are now almost -Wall clean.
- redefined atomic_t
- deleted many, many unused variables
- some minor code cleanups found using compiler warning.
 
615 6901 d 10 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
609 6902 d 4 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
578 6904 d 19 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....
