646 6705 d 5 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.		  
644 6705 d 14 h jermar /kernel/trunk/arch/ Remove unnecessary files or files that are now part of the boot/ module.  
640 6706 d 4 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
635 6707 d 4 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.		  
634 6707 d 17 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Better way of trap table organization.
Kernel trap handlers now "stay" on addresses on wich they were linked.		  
633 6708 d 6 h palkovsky /kernel/trunk/arch/ Fixes of compilation of atomic.  
632 6708 d 6 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add trap_install_handler().
Use trap_install_handler() to install register window clean, spill and fill handlers.		  
631 6708 d 6 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
630 6708 d 8 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Register window clean, spill and fill handlers.		  
629 6708 d 8 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6708 d 10 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
627 6708 d 11 h jermar /kernel/trunk/ Fix ia64 and sparc64 to compile with new atomic_t.
Fix rwlock test #5 and semaphore test #1 to compile with new atomic_t.

sparc64 work.
TBA must be set before a function call when MMU is switched off.		  
626 6708 d 11 h palkovsky /kernel/trunk/ Less checking in kernel config,
allow DEADLOCK_DEBUG only for SMP.		  
625 6708 d 12 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 6708 d 12 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6708 d 17 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 6709 d 7 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
621 6709 d 13 h palkovsky /kernel/trunk/ better architecture line  
620 6709 d 13 h palkovsky /kernel/trunk/ Build string now contains correct architecture.  
619 6710 d 2 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Functions for disabling/enabling MMU.
TLB initialization.
Identity mapping of first 4M for kernel.
Switch to kernel copy of trap table.
