723 6756 d 3 h palkovsky /kernel/branches/falloc_bad/generic/src/mm/ Cannot printf in frame_alloc, because on ia32/amd64 it
would print before ega_init and that stucks fs.		  
722 6756 d 4 h palkovsky /kernel/branches/falloc_bad/generic/src/main/ Fixed bad stack settings in main for main_bsp_separated_stack.  
721 6756 d 9 h bondari /kernel/branches/falloc_bad/ Failing frame allocator changes.  
720 6756 d 9 h bondari /kernel/branches/falloc_bad/ Failing frame_alloc branch - revision 719  
718 6758 d 2 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 6758 d 5 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
714 6758 d 6 h decky /kernel/trunk/ syscall handler return value
uspace task termination (primitive)		  
712 6758 d 7 h decky /kernel/trunk/ "Hello world" from user space :)  
711 6758 d 7 h decky /kernel/trunk/generic/src/mm/ fix wrong frame memory access  
704 6760 d 7 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.		  
703 6760 d 10 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 6763 d 1 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 6763 d 10 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
689 6765 d 7 h bondari /kernel/trunk/ Frame alloc test #1  
687 6765 d 7 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
686 6765 d 8 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
684 6765 d 8 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 6765 d 9 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
678 6769 d 2 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
677 6769 d 5 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6769 d 5 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
675 6769 d 10 h jermar /kernel/trunk/generic/src/ Clean up.  
674 6769 d 12 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6770 d 1 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6771 d 2 h vana /kernel/trunk/ i8042 bug fix...  
668 6774 d 8 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 6778 d 22 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
662 6781 d 1 h decky /kernel/trunk/ initial syscall table support  
659 6782 d 12 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
654 6784 d 6 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 6784 d 23 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 6785 d 1 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 6786 d 0 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 6787 d 0 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
635 6787 d 23 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 6789 d 2 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
629 6789 d 4 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6789 d 5 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6789 d 7 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 6789 d 8 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.
