752 6775 d 5 h jermar /kernel/trunk/generic/include/ Replace % operator by explicit overflow test to make this ADT compile on ia64.  
747 6778 d 22 h jermar /kernel/trunk/ ia64 work.
Add nice wrappers for thash and ttag instructions.
Add nice wrappers for accessing reion registers and PTA.
Fix set_vhpt_environment().
Allocate and initialize page_ht (a.k.a. VHPT).

Add missing header to sparc64.
Remove excessive header from debug.h.		  
735 6783 d 4 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
730 6784 d 4 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
729 6784 d 4 h jermar /kernel/trunk/generic/include/ In-array FIFO implementation.  
727 6785 d 23 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
724 6788 d 0 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
718 6790 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 6790 d 3 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
712 6790 d 4 h decky /kernel/trunk/ "Hello world" from user space :)  
703 6792 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().		  
699 6795 d 8 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
689 6797 d 5 h bondari /kernel/trunk/ Frame alloc test #1  
687 6797 d 5 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
686 6797 d 6 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
684 6797 d 6 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 6797 d 7 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
681 6797 d 9 h jermar /kernel/trunk/ Minor changes.  
678 6801 d 0 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
676 6801 d 3 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
673 6801 d 23 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
669 6805 d 23 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().		  
664 6810 d 20 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
662 6812 d 23 h decky /kernel/trunk/ initial syscall table support  
651 6816 d 21 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 6816 d 23 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.		  
631 6821 d 0 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
629 6821 d 2 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6821 d 3 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6821 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.		  
624 6821 d 6 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6821 d 11 h jermar /kernel/trunk/ Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros.
SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations
in dynamically allocated structures on which spinlock_initialize() is called after
their creation.
SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations
of global spinlocks. It declares and initializes the spinlock.
Moreover, both macros are empty on UP so that -Wall warnings about unused structures
get supressed.		  
622 6822 d 1 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
615 6823 d 10 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
609 6824 d 4 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
607 6824 d 5 h palkovsky /kernel/trunk/ Fixed weird simics panic.
Run kconsole, if we panic. This currently works in gxemul,
simics. In mips we need to modify the simulator.
On ia32 we need a function, that would speak directly to the chip
and fetch the character using polling.		  
601 6825 d 1 h palkovsky /kernel/trunk/ Added some readline functionality to kconsole.
Arrows editing, history, tab completion.		  
597 6825 d 8 h jermar /kernel/trunk/ Finer grained TLB invalidate functions for ia32 and amd64. Not yet deployed.  
596 6825 d 21 h jermar /kernel/trunk/ kconsole cleanup.
Separate commands from the engine.		  
594 6826 d 2 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).
