I do not think you should add it inside *kernel*. Proper acceleration
support really belongs to X...

X, fbdev apps, gpm ... acceleration curves are typically done in HW,
thus it makes sense in this case to have it in the kernel driver
(besides, it should be fairly simple anyway) when it's in normal mode.
When it's in raw mode for use by the synaptics X driver, if course, it's
expected that those things are to be done by that driver.

It should be doable once in gpm, all other apps can use gpm's repeater
mode...

...but you are right, doing it in /dev/input/mice emulation layer
makes some sense. OTOH I thought we were moving away from
/dev/input/mice... Its Dmitry's call I guess.

Heh, yes, it is. No hurry anyway, I finally got synaptics working
properly in X ...
Why would we move away from the mouse mux ? It's proven to be very
useful to me at least :)

It is very limited - number of buttons, wheels, etc. Once X supports
hotplugging mouse multipexor outgrows its usefullness (GPM can simply
be restarted every time we detect new input device).

I dont have so much information on 74xx and marvell's
bridge chips but for an advice,investigating the
latest u-boot source that includes DB64360 (marvell
discovery II) DB64460(marvell discovery III) board
support may be helpful, DB64360 bridge chip is the
same as MVME6100,then find the differences of two
boards and start to modify them.

* kernel hang on 'now booting the kernel'
From: Ali Paikan @ 2005-12-25 10:18 UTC (permalink / raw)
To: linuxppc-dev
Dear Sir,
I am a student and I tried to install Linux on ML300 board. I need that fo=
r
doing my final project but I have many problems.
I compiled the open source PowerPC kernel (linuxppc_2_4_devel) with a cross=
compiler which I built it by Dan Kegel cross tools. Before compiling, I
updated xparameters_ml300.h according to my base system design from Xilinx =
EDK.
Next, I tried to download kernel ELF file to board and every thing seen wel=
l.
But My kernel hanged up when it was going to load main kernel image with sh=
ow
this message on serial console:
loaded at: 00400000 004B01E4
board data at: 004AD13C 004AD154
relocated to: 00405648 00405660
zimage at: 00405C13 004AC65E
avail ram: 004B1000 08000000
Linux/PPC load: console=3DttyS0,9600 ip=3Doff root=3D/dev/xsysace/disc0/par=
t3 rw
Uncompressing Linux...done.
Now booting the kernel
I debugged the kernel and results showed memory initialized and load_kernel=
function decompressed image into address 0x0 as well. (I can see tree NOP
instructions from address 0x0).
But, I am not sure about next step in jumping to address 0x000C and running=
the main part of kernel.
I wondered more when I tried to make a Xilinx System ACE file with Impact. =
It failed too with showing this fatal error:
FATAL_ERROR:GuiUtilities:WinApp.c:710:$Revision - This application has
discovered an exceptional condition from which it cannot recover. Process
will terminate. To resolve this error, please consult the Answers Database=
and other online resources at http://support.xilinx.com. If you need furthe=
r
assistance, please open a Webcase by clicking on the "WebCase" link at http=
://support.xilinx.com.
I don't have any problem for making system ace from other ELF files.
Might it be for my bad compilation?
Is my base system building for FPGA not correct?
Where is my wrong?
For more information I attached my all configuration and log files at end o=
f
this mail.
I am too great if you help me in this case and I look forward to hearing fr=
om you.
Sorry my pure English!
Sincerely,
Ali Paikan

* [PATCH/RFC?] usb/input: Add support for fn key on Apple PowerBooks
From: Michael Hanselmann @ 2005-12-25 21:20 UTC (permalink / raw)
To: linux-kernel; +Cc: linux-input, linuxppc-dev, linux-kernel
This patch adds a basic input hook support to usbhid because the quirks
method is outrunning the available bits. A hook for the Fn and Numlock
keys on Apple PowerBooks is included.

Well, we have used 11 out of 32 available bits so there still some
reserves. My concern is that your implementation allows only one
hook to be installed while with quirks you can have several of them
active per device.
As far as the hook itself - i have that feeling that it should not be
done in kernel but via a keymap.

I haven't looked at the details so I can't comment much there, though
the hook has the interest of making it possible to have it in a module
that gets separately loaded if necessary, no ? Maybe the driver could
maintain a list of hooks ?

While I understand your feeling, it's a bit annoying in this specific
case because previous models did this in hardware and all mac keymaps
already account for that. Knowing how nasty it has been to get mac
keymaps updated and in a good shape, and to get distros to properly get
them, it makes a lot of sense to have this small hook in the kernel that
makes the USB keyboard behave exactly like the older ADB couterparts.

Our board is PQ2FADS_ZU,and we bought a BDI2000 to debug it.
There is a LH28F016SC flash in the PQ2FADS_ZU board.
I tested the default .cfg (for 8260ads) to driver LH28F016SC flash,but it didn't work.
How to modify the .cfg file? thanks.

* Can I use the system call provided by uboot in an assembly language program as in ppcbug?
From: Zhang Xin-W22390 @ 2005-12-26 12:43 UTC (permalink / raw)
To: linuxppc-embedded
[-- Attachment #1: Type: text/plain, Size: 494 bytes --]
Hello,
I want to call some system calls to do input/ouput in assembly language
program, and does uboot provide such syscall? As in PPCBUG, I can
program the following code:
li r10,0x0022
sc
to do an output to console.
I know I can program a standalone application using printf() to achieve
this function, as illustrated by the example uboot provides. Instead, I
want to use assembly language.
Thanks and Regards.

I don't know of public example code but in general it is pretty easy.
Just set up the EBC registers to map your device into some unused
address space, and then use ioremap() and friends to access the bus.

If you are running in the U-Boot environment, then you can use
standard C programs; read about "standalone applications" - but this
is off topic here; please read the docs and post any remaining
questions on the u-boot-users mailing list.
Once you started the Linux kernel, then all of U-Boot is gone and
dead and there is no way to call any U-Boot code any more - except by
resetting the board.

Hi All:
I want port Linux system to the MVME6100, I found moto has this kind of
patch for the MOTO SBC, just like patch-2.6.6-mcg.rm01.gz file.
Any know how and where can I download it?
Thank you very much.

* Which CAN driver to port to for PPC
From: David Jander @ 2005-12-27 16:30 UTC (permalink / raw)
To: Wolfgang Denk; +Cc: linuxppc-embedded
Hi,
We have developed CAN hardware based on the Philips SJA1000 controller hooked
to a MPC8xx based processor board. Now we want to write driver support for
it. My first try was lincan-0.3.1, which seemed quite well written at first
glance. Porting was easy too, and the driver works fine on our board with the
latest kernel (2.6.14).
But.... this driver lacks a proper way of checking the status of the CAN
controller from userspace :-( Not that nice after all!
Then I see on the DENX website, mention of Rubini's OCAN (mostly useless to
us), and Peak's PCAN drivers (there is a port for MPC5200 on DENX's site). No
word about lincan, though.
The reason I suppose is, someone already figured out that lincan is not a good
choice for whatever reason (status reportability ??), right?
Before beginning to re-invent wheels and re-discover known problems in certain
CAN driver architectures, could someone please point me to the right place to
start looking for answers (if that place exists) or just give the answer,
opinion or experience with one of PeakCAN, lincan, can4linux, etc...?
I am again puzzeled about which way to go.
Thanks for any advice,

* [PATCH] PPC44x EMAC driver: disable TX status deferral in half-duplex mode
From: Eugene Surovegin @ 2005-12-27 20:36 UTC (permalink / raw)
To: Jeff Garzik; +Cc: netdev, linuxppc-embedded
Disable TX status deferral (EMACx_MR[MWSW=001]) in half-duplex mode.
I have two reports when EMAC stops transmitting when connected to a
hub. TX ring debug printouts show complete mess when this happens,
probably hardware collision handling doesn't work quite well in this
mode.
This is relevant only for SoCs with EMAC4 core (440GX, 440SP, 440SPe).
Tested on 440GX.

I need to port ocan to support SJA1000 on an ARM device, as a client
asked for it. Also, another client asked for a 2.6 port, so all of
this will happen pretty soon (2-3 weeks). I don't know if that makes
any difference.

From: siman @ 2005-12-28 1:55 UTC (permalink / raw)
To: linuxppc-embedded
In-Reply-To: <20051228010003.3F26D6894D@ozlabs.org>
Hi all:
I want to port Linux to the prpmc610 system and mvme6100,does any one has
the experience for these boards?
The prpmc610 has the ppc5bug.
Also I found there is file for that named "patch-2.4.25-mcg.rm01.gz ", it
was patch for mvme6100 on the standard kernel. Who knows how can I get the
file?
Thanks all.
