According to the spec we need to set it before taking over the MMU,
but we can't call it before arch_mmu_init(), since we need the OF
to allocate the page table. So we do it after we have allocated
the new page table.
* Added PPC specific kernel_args: The virtual address ranges we want
to keep in the kernel. We fill that in with the translations we
find when initializing the MMU stuff. We remove the memory the
boot loader occupies from those. Besides the stack for the boot
loader only the OF stuff remains.
* arch_mmu_allocate() now starts to search at KERNEL_BASE for a free
virtual address when no particular address is requested. This saves
us further trouble in the kernel, since those allocations would
need to be remapped otherwise.

brick wall collisions. Along the way I found a few defines that no longer
exist in Haiku - changed B_BEOS_VERSION_DANO to use Haiku versions (anyone
rebuilding under Dano might want to undo it). By the way, the BeOS version
number define system might be worth using, since it's a numerical compare
rather than #if defined(V1) || defined (V2) || defined (V3) and so on.
What sort of errors? Besides needing libzeta.so for some things, the
networking compatibility compile doesn't work (libbind and all that).
Some examples among many:

the fact that I couldn't find ptesync in an otherwise more complete
documentation I downloaded yesterday made me suspicious.
* arch_cpu_global_TLB_invalidate() uses tlbia now. The instruction is
optional, but so is tlbie (how I understood it is that both exist,
when the architecture implementation has a TLB). And the former loop
looked just scary.
* Implemented arch_cpu_user_TLB_invalidate(). It does just the same as
arch_cpu_global_TLB_invalidate().
* Some changes with respect to synchronization required on page table
and segment register updates.
* Some more minor renaming. Pulled a new function
remove_page_table_entry() out of unmap_tmap().
* In arch_vm_translation_map_init_post_area() we do now remap the page
table into the kernel address space, if it was without before. The
page table might actually be a good application for BAT, though.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@15773 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Renamed occurrences of ASID/asid to VSID/vsid where appropriate.
* vm_translation_map_arch_info::vsid_base is now the first usable
VSID and doesn't need to be shifted anymore.
* Changed the VSID base shift from 4 to 3, since we need only 8 VSIDs
per team.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@15772 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Fixed several off-by-one comparisons with num_pages.
* vm_alloc_virtual_from_kernel_args() now makes sure the allocated
region lies within the kernel address space (or is at least
>= KERNEL_BASE).
* Simplified one or two patches.

fill_page_table_entry() by a ptesync(). Mapping the kernel heap
took about 2 minutes here before.
* Added missing shift of the asid_base in ppc_translation_map_change_asid().
* Commented out the BAT stuff in arch_vm_translation_map_init_post_area().
Besides that I think it won't work that way, it made the page table
unaccessible; though I'm not sure why.
* Added a bit of documentation to the beginning of the file. Should give
enough information to understand what happens here without further
detailed knowledge about the architecture.

BeMail uses 2, Terminal (under Dano) 4, and Tracker as well as pe 3 - so 3 seems
to be a good compromise.

* added another optimized bitmap drawing routine
for B_OP_ALPHA and BGR[A]32 bitmaps. When actual
blending takes place, it is more than 1.7 times
faster than R5, and about the same speed when
the bitmap is fully opaque.

arch_mmu_allocate() to set the "cache inhibited" flag. One negative
effect was that for such memory the lwarx instruction (used by the
atomic_*() functions) does "... cause the system data storage error
handle to be invoked...", as the architecture specification puts it.

with quite good results I might add. Drawing B_RGB32
bitmaps is more than 1.2 times faster than on R5, while
B_CMAP8 bitmaps are slightly slower. The optimization
is only for B_OP_COPY and unscaled bitmaps
(B_RGB32 and B_CMAP8). Drawing only parts of the bitmap
is supported. Adding optimization for scaled bitmaps
should be beneficial, since the generic version is 2 two
4 times slower. I think it gets even worse for partial
bitmaps.

{HAIKU,HOST,TARGET}_KERNEL_PIC_{CC,LINK}FLAGS which define the
compiler/linker flags specifying the kind of position independence
the kernel shall have. For x86 we had and still have -fno-pic, but the
PPC kernel has -fPIE (position independent executable) now, as we
need to relocate it.
* The boot loader relocates the kernel now. Mostly copied the relocation
code from the kernel ELF loader. Almost completely rewrote the PPC
specific relocation code, though. It's more correct and more complete now
(some things are still missing though).
* Added boot platform awareness to the kernel. Moved the generic
Open Firmware code (openfirmware.c/h) from the boot loader to the kernel.
* The kernel PPC serial debug output is sent to the console for the time
being.
* The PPC boot loader counts the CPUs now and allocates the kernel stacks
(made OF device iteration a bit more flexible on the way -- the search
can be restricted to subtree). Furthermore we really enter the kernel...
(Yay! :-) ... and crash in the first dprintf() (in the atomic_set()
called by acquire_spinlock()). kprintf() works, though.

probably increase the values we got from BScrollBar::GetSteps(), though, as
it's a bit slow.

with the "EventMask" test app the last time:
* The focus view didn't get any mouse messages anymore if there was a permanent
B_POINTER_EVENTS view.
* B_KEYBOARD_EVENTS now works again.
* B_MOUSE_WHEEL_CHANGED messages no do arrive their targets without prior
keyboard input.
* Added TODO item that other focus messages don't go through to the app without
keyboard input (fix only works for B_MOUSE_WHEEL_CHANGED).

wider, so that they completely fill up the space they have (making them nicely
aligned to the surrounding border).
* the placement controls now accept up to 5 bytes (for things like "-1000").
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@15751 a95241bf-73f2-0310-859d-f6bbb57e9c96
as cached_block::data - which led to a crash as block_cache::FreeBlock() tried to
free both later.
Since neither cached_block::parent_data nor cached_block::original are supposed
to be != NULL in block_cache::FreeBlock(), they are no longer freed, but the system
panics if one of them is not NULL.
This should fix bug #77.

* The left and right box should now always look aligned horizontally
(at least under Haiku).
* Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@15748 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Less flickering when drawing the label: the area of the label is now
clipped, so there is no need to fill the background again.
* Consumed the last reserved member for the bounding box of the label.
* More or less rewrote the header.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@15747 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Better error reporting when writing the attributes.
* Minor cleanup.

preferences app writes its info with this type (instead of B_MESSAGE_TYPE as
Be's does).
It's now possible to set the background image for Tracker under Haiku.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@15742 a95241bf-73f2-0310-859d-f6bbb57e9c96

attribute is longer than B_MIME_TYPE_LENGTH.
* NodeInfo::GetType() now null terminates the attribute; you cannot expect
that strings in attributes are null terminated (it already wrote the null
byte to B_MIME_TYPE_LENGTH - 1 for safety, but why not do it right?).

when the image had been rebuilt. That was a bit annoying...

panel window (and thus the text is no longer cut off under Haiku).
Instead of only writing "JPEG Image" for JPEG images, and nothing for
all other image types, the MIME types short description is now displayed
(or the MIME type itself if no such description exists).
