void after turning off BAT for the segment containing itself.
The monster macro for the exception vector code was not really
elegant besides being too long for the 32 byte performance
monitor exception slot. Furthermore wasting three of the SPRG*
registers as cheap scratch memory wasn't that nice either.
We now have a three-step approach: The exception vectors
themselves contain only five instructions which branch to common
code at the beginning of the same physical page. That one sets
up BAT for itself, turns address translation back on and jumps
into the kernel. There we turn off BAT again, dump an iframe,
and enter the actual exception handler (/dispatcher). Upon return
the registers are restored from the iframe and we get back to the
place where the exception occurred.

and 24 bits the set upper bits were overwriting the upper bits of
the word at the target location (usually something like a branch
instruction).
This is the kind of bug that easily take six hours to find, especially
when working with interrupt code and being convinced that the problem
must be related.

* fixed weird pointer conversion in SetStyle()
* fixed a potential mix up in operator=() in case the
other ServerFont has fStyle == NULL
ServerWindow:
* the WindowLayer fTopLayer cannot be deleted by
client request, just for safety reasons
* the link is flushed if there is no drawing engine,
but this case is theoretical only
* deleting the ServerWindow object syncs with the
client, so that when BBitmaps are deleted, they
can be sure there are no pending messages (which
would be executed in a nother thread)
* there is no timeout anymore when sending messages
to the client, which made absolutely no sense
AGGTextRenderer:
* renamed fFontManager to fFontCache, because that's
what it really is
* fLastFamilyAndStyle defaulted to the system plain
font and therefor that font was never loaded when
the font never changed meanwhile
DrawingMode:
* I'm not quite sure but I think there was the
potential of a division by zero, at least I
had crashes with "divide error"
HWInterface:
* fix update when the cursor shape changed in
double buffered mode
ViewLayer:
* since the top layer is never really deleted
before its time has come, it is not necessary
to set it to NULL in the ViewLayer destructor
ViewLayer/WindowLayer:
* added a function to collect the view tokens
that are affected by an update session
EventDispatcher:
* use the importance of the message for the timeout
in _SendMessage()
* drop mouse moved events in the server if we're
lagging behind more than 5 ms (Axel, maybe review)
View:
* there were some problems with the locking
of the BWindow looper in RemoveSelf(), since
this is called from the window destructor,
also of BWindows from BBitmaps, which have
never been run (this might need review), at
least I seem to have solved the crashing
problems introduced by actually deleting the
view hirarchy in the BWindow destructor
* fixed _Draw() for being used non-recursively,
temporarily disabled DrawAfterChildren, which
didn't work yet anyways (because views cannot
draw over children in the server yet)
Window:
* small cleanup when deleting shortcuts
* sync with the server when having send
AS_DELETE_WINDOW (see ServerWindow above)
* fixed locking in Begin/EndViewTransaction()
* removed folding of _UPDATE_ messages, since
there is only one ever in the queue
* set the fInTransaction flag during an update,
I plan to use this in BView later to
flush the link when drawing outside of an
update
* BView::_Draw() is now called by view token,
this gives the next leap forward in speed,
the overhead because of drawing clean views
was considerable

The time base conversion factor is the 32 bit value
2^32 * 1000000 / time base frequency,
so the system time can be computed by
system time = time base * conversion factor / 2^32.
The expression in system_time() looks more complicated now, but is
actually much faster (factor 2.5 on my Mac mini). I'm positively
surprised, how good the assembly looks, that GCC 4 generates. There's
not that much potential for optimization by hand-coding the function.

* The generic physical page mapper reserves the virtual address range
for the IO space now, so that noone can interfere until an area has
been created. The location of the IO space is no longer fixed; it
didn't look to me like it was necessary for x86, and we definitely
need to be flexible for PPC.

available under R5).
The solution is a bit messy, but we have to live with it :-)
The runtime loader now patches the __gRuntimeLoader symbol in libroot.so to point
to its exported structure instead of passing it to the init functions as an
argument.

pass its path to the kernel, where it's opened and used for
getting/setting the real time. The expensive atomic_*64() on PPC
32-bit make things a bit more complicated. Moreover, missing
64 bit multiplication and division instructions won't really
allow system_time() to be anywhere near as fast as on x86. :-/

Basically the architecture specific code is now responsible to
init and make use of the platform specific code, now. The reason
being that we have only one kernel per platform and thus cannot
decide at compile time, which platform to use (if any).
The PPC implementation features an abstract base class PPCPlatform
(implemented for all supported platforms) through which platform
support is provided.

* Improved error message in case the initial shell couldn't be executed.
* Disabled setting the colors via arguments, mostly because it just did quit
the app in case there were any arguments and no /etc/rgb.txt file. This
allows Terminal to be used by the debug_server instead of MiniTerminal.

them to the kernel via kernel_args.

types to <OS.h>.

remapping stuff into separate functions and made them available to

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).

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.

* 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.

* 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).

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.

* ViewLayer now deletes the view bitmap on destruction, if any.
* BitmapManager::Delete() now also accepts NULL bitmaps.

* if file panels shouldn't be quit, we no longer call QuitRequested() for
them and stop quitting windows (which left normal windows open, because
file panels always return "false" in QuitRequested())

and ResizeBy()
* WindowLayer::SetSizeLimits() needs to be called with the
AllWindows lock held
* I was observing weird behaviour with "unclickable" windows
that I might have fixed by explicitly excluding invisible
windows from Desktop::WindowAt(), there might be something
wrong with the "current" window list though, Axel would know
* finally found the problem with "delayed background clearing"
* enabled delayed background clearing and removed unnecessary
code. It should be more efficient, since it clears larger
areas at once, and it solves the problem of views unable to
draw into regions that are pending for another update - among
other things, updates in resizing windows are more fluent,
especially for B_FULL_UPDATE_ON_RESIZE views. "Cut off" scroll
bars should no longer appear when the view being scrolled takes
too long to redraw.

* Moved BGWindow stuff into Backgrounds.cpp.
* Cleanup to match our style guide better.

I wouldn't be surprised, if more wrappers are still missing.

specifying whether only the exact supplied address is acceptable. If
false, the address is considered a hint only. It will be picked, if
available, otherwise a greater address is tried to be acquired, and
as last resort any address. This feature is only implemented for PPC.
It is needed since the preferred kernel text base address 0x80000000
might not be available (and actually isn't on my Mac mini).
* Fixed a bug in the PPC memory management code:
is_{virtual,physical}_allocated() were checking whether the given
range was completely contained by an existing range instead of
checking for intersection. As a consequence we could (and did) allocate
a range intersecting with already allocated ranges. The kernel segment
thus overwrote OF memory for instance.
* The ELF loader makes sure that it got both text and data segment of
the image to be loaded.
The PPC boot loader successfully loads kernel and modules now. Next
comes the hard part, I'm afraid.

platform_allocation_region(). Since the callback stuff doesn't seem to
work, the Open Firmware didn't ask us to allocate memory in turn, and
thus we didn't know about the range that had been mapped and reused it
later.

into a new frame_buffer_support.h
* added blend32 routine for blending a certain color with
a scanline in the frame buffer
* added "solid" versions of B_OP_ALPHA drawing with
B_ALPHA_OVERLAY alha function (blending on top of
a non-transparent background such as the frame buffer)
* implemented an optimized shortcut for alpha blended
FillRect() in Painter
* used the "packed" version of scanlines for shapes with
an outline thicker than 4 pixels (and filled shapes anyways),
this improves drawing speed when there are a few anti-aliased
pixels at the beginning of a scanline, then a solid fill and
some anti-aliased pixels at the end of the scanline. Such as
large letters.
To summarize: The alpha blending in Painter seems to be about
1.45 times faster than on BeOS R5 which benefits drawing large
shapes. For example, drawing a large alpha blended rounded rect
is 1.28 times faster on the Haiku app_server. On the other hand,
B_OP_COPY is quite tough to beat. It is currently 10 times faster
on R5. But a great deal seems to be caused by the Painter
rasterization algorithm itself, since commenting out the actual
drawing doesn't gain any speed.
The other useful experience I collected was that reading and
writing and over the PCI bus in the same loop really hurts
performance. It is actually faster (like 1.8 times!!) to allocate
a second buffer, read from frame buffer into that, doing the
blending at the same time, then writing the buffer back to the
screen.

and thus, it could be used again which led to a crash.
Changed the free ranges list from a singly linked list to a doubly linked
list so that not all free ranges have to be searched for the one to be
freed anymore.

the modified bit set were written back (that's the case when they weren't put into
the modified pages queue yet), they were enqueued into the active queue twice, messing
up the page lists with various effects - this little thing took me busy for the last
few days :-/
* Improved the "page" debugger command: it now prints out much more info, and also lets
you lookup pages via physical address.
* The dump commands are now using kprintf() instead of dprintf().

IP, and UDP, as well as a home brewn UDP based protocol, "remote disk",
which provides random access to a single remote file/device. The Open
Firmware flavored boot loader automatically initializes the net stack,
searches for a remote disk, and tries to boot from it, if the boot
device is a network device (e.g. when loading the boot loader via
TFTP).
This is quite nice for developing with a two-machine setup, since one
doesn't even need to install Haiku on the test machine anymore, but can
serve it directly from the development machine. When the networking
support in the kernel is working, this method could even be used to
fully boot, not just for loading kernel and initial modules.

argument value of 0 should only free the old allocation.

* bfs_inode must be packed, otherwise the structure is larger due to
different alignment requirements.
* The off_t array returned by bfs_inode::Values() is in on-disk
endianess. This was ignored in some places. Hope I squashed all
occurences.
Those fixes should probably be back-ported to the kernel add-on, too.
Will do that when I get to that point in the kernel, unless someone
beats me to it.
The PPC boot loader does at least find the kernel on a BFS volume now.
Haven't dared to let it be loaded yet.

that later. The PPC kernel builds again, now.

of_call_method() which is actually an implementation of the
"call-method" client function.
* of_interpret() announced one less return value than actually needed.
Seemed to work anyway, though.
