Issues with running iRT
Posted: Sep 02, 2007 04:05:03 AM

Hi:

Thanks for making the iRT demo available!

I am trying to install this on my Fedora 7 PS3 installation running 2.6.23-rc3 kernel.

When I run iRT, it gave me the following error:

No controllers found in /dev/input
Please make sure that the controller
is plugged in with the USB cable

However, /dev/input/js0 and /dev/js0 are both present.

Is it possible to run the demo without the gamepad (I have a USB keyboard attached).

Thanks,

Bernard

Okay got this working with YDL 5 running 2.6.16-20061110.ydl.2ps3. Basically I guess iRT is looking specifically for /dev/input/event* files which are not present in 2.6.23. This is the contents for my /dev/input:

ls -l /dev/input/

total 0
crw------- 1 root root 13, 64 Sep 1 20:30 event0
crw------- 1 root root 13, 65 Sep 1 20:30 event1
crw------- 1 root root 13, 66 Sep 1 20:30 event2
crw------- 1 root root 13, 0 Sep 1 20:30 js0
crw------- 1 root root 13, 63 Sep 1 20:30 mice

Is this an iRT issue or kernel issue?

Cheers,

Bernard

Finally got it working with 2.6.23-rc5 kernel. Make sure that you have:

CONFIG_INPUT_EVDEV=m

This will create the /dev/input/event* files.

Geoff Levand has already added this to his most recent ps3-linux git kernel tree.

To the IBM folks -- are there plans to make the full version (the one which supports load balancing on PS3 cluster) available to the general public too?

Thank you,

Bernard

All you need is the Device Drivers -> Input device support -> Event interface (CONFIG_INPUT_EVDEV=m or CONFIG_INPUT_EVDEV=y) in your kernel config and in the case of the module load it properly.

Bernard,

Thanks for working through the controller issues.
We originally coded to the /dev/input/js0 device but then found it was missing from the YD 5.0.2 image so we recoded to the /dev/input/event* devices before this release. This has been an on going problem and Joaquin can fill in the details if needed.

The cluster question, yes if we find that users desire this feature we could make it available. Our initial goal with this release was to keep it simple but still give people an idea of how Cell performs at ray-tracing.

I've been trying to get this working on Ubuntu 7.04 on my (european) PS3 (well, it 's really the Ubuntu 7.04 kernel with beta 7.10 packages)

I'm almost there... Got the rpm's unpacked and put in /opt just fine.

When I start up iRT it loads the scene and waits for me to press PS on the pad (/dev/input/event3). But it doesn't respond to my presses.

/dev/input/event3 does seem to be my pad, if I cat /dev/input/event3 and press buttons, the screen fills up nicely with data.

I'm thinking there might be some hardware differences between the territories, so I've provided a hexdump of what happens when I press the PS button (cat /dev/input/event3 | hexdump -C)

I hope somebody can either help me out here or perhaps fix iRT if this should be a problem in the code. I'd love to see it running!

Best regards,
Carsten Sorensen

Do you have multiple PS3 controllers connected?

What does
"dmesg | grep -i sony"
show?

Here is the output from /dev/input/event0 (the joystick on my FC6 machine)

00000000 46 e6 e5 16 00 0c ce ad 00 03 00 00 00 00 00 8b |F...............|

00000090 46 e6 e5 17 00 00 1c e5 00 00 00 00 00 00 00 00 |F...............|

We read from dev/event and look for an event type of 1 and a button modifier of 304.

In the event output it looks something like (on my machine)

000000c0 46 e6 e5 17 00 02 18 cb 00 01 01 30 00 00 00 01 |F..........0....|
or
00000130 46 e6 e5 17 00 03 2a 4c 00 01 01 30 00 00 00 00 |F.....*L...0....|

| ^ Button Modifier 304 = 0x130
^ Event code 1 = 0x1

Depending on if the button is pressed.

I'm sorry, the spacing was mangled in my post. The 0x0001 and 0x0130 are in the second half of the output.

Hi Joaquin,

No, I just have the one controller connected.

"dmesg | grep -i sony" output:

http:// 33.371757 scsi 0:0:0:0: CD-ROM SONY PS-SYSTEM 302R 4084
http:// 38.434654 input: Sony PLAYSTATION(R)3 Controller as /class/input/input3

http:// 42.747011 scsi 3:0:0:2: Direct-Access Sony GL819 CF 1.08 PQ: 0 ANSI: 0

I'm not sure what you're looking for here, am I missing a kernel module perhaps? I've noticed that the xpad module (for XBox controllers) sometimes loads, which changes the /dev/input/event3 output slightly... It wasn't loaded when I did the output in my original post though.

Thanks,
Carsten Sorensen

I've been playing some more with my pad, I can get it to generate different numbers for the button modifier, from 0x120 to 0x12F depending on the button pressed - but PS always generates 0x120, the same as select. Very odd. In fact I can't tell the difference between the messages -

select:

I'm not sure what would cause the PS button to report the same code as select. I presume the PS button works as expected in GameOS right? Are you able to turn your PS3 off and on using the PS button when in GameOS?

Thanks,
Joaquin

Hi:

I've the same problem, when running iRT on YDL 6.1 I got the following error

No controllers found in /dev/input
Please make sure that the controller
is plugged in with the USB cable

I've installed nothing but the 3 rpm containing iRT and the scenes; the cellsdk was already installed.
/dev/input/js0-1 are present but when I connect my sixaxis on usb I got this error :

sony: probe of 0003:054C:0268.0006 failed with error 17

but still when I cat /dev/input/js0 screen fills up with data when I press buttons on the sixaxis

any ideas ??

thanks
