727 6822 d 3 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
724 6824 d 4 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
718 6826 d 4 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 6826 d 7 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
714 6826 d 8 h decky /kernel/trunk/ syscall handler return value
uspace task termination (primitive)		  
712 6826 d 8 h decky /kernel/trunk/ "Hello world" from user space :)  
711 6826 d 9 h decky /kernel/trunk/generic/src/mm/ fix wrong frame memory access  
704 6828 d 9 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.		  
703 6828 d 12 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().		  
701 6831 d 3 h jermar /kernel/trunk/generic/src/mm/ Fix zone_print_one() and zone_print_list().
- add missing spinlock_unlock()
- add missing interrupts_disable() and interrupts_restore()
Coding style fixes and cleanup.		  
699 6831 d 12 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
689 6833 d 9 h bondari /kernel/trunk/ Frame alloc test #1  
687 6833 d 9 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
686 6833 d 10 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
684 6833 d 10 h jermar /kernel/trunk/ Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface.		  
683 6833 d 11 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
681 6833 d 13 h jermar /kernel/trunk/ Minor changes.  
678 6837 d 4 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
677 6837 d 7 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6837 d 7 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
675 6837 d 12 h jermar /kernel/trunk/generic/src/ Clean up.  
674 6837 d 14 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6838 d 3 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6839 d 4 h vana /kernel/trunk/ i8042 bug fix...  
669 6842 d 3 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().		  
668 6842 d 10 h bondari /kernel/trunk/generic/src/console/ Zones related commands infrastructure for console. Also fixed small bug that caused infinite loop during command parsing  
664 6847 d 0 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
662 6849 d 3 h decky /kernel/trunk/ initial syscall table support  
659 6850 d 14 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
654 6852 d 8 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.		  
651 6853 d 1 h decky /kernel/trunk/ remove arch/$ARCH/boot where not needed, change global Makefile accordingly
remove early_mapping() (breaks ppc32 for now)
change early heap initialization (required for init to work)		  
650 6853 d 3 h jermar /kernel/trunk/ sparc64 work.
Implement interrupt_disable(), interrupt_enable(), interrupt_restore() and interrupt_read() functions.
Fix context save/restore to save/restore register %i7.		  
646 6854 d 2 h jermar /kernel/trunk/ Fix cpu_init(): frame_alloc() can return 0 as the valid address of block of frames. Do not signal error.

sparc64 work.
Reorganize kernel vs. userspace memory layout.
Add panic_printf().
Turn dummy() into nop rather than into infinite loop.		  
640 6855 d 2 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
635 6856 d 1 h palkovsky /kernel/trunk/ Fixed kconsole resolution of similar commands.
Add commands to debugger to allow for simple profiling or
calling debug actions if needed.		  
631 6857 d 4 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
629 6857 d 6 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6857 d 7 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6857 d 9 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.		  
624 6857 d 10 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.
