Xorg 7.3

2009-07-01T11:03:35Z

Has anyone developed working drivers for this version of Xorg yet? I tried
compiling the nvxbox source available on sourceforge CVS but got no joy.

cromwell problem

2009-01-03T16:20:44Z

Hi,

i've a problem with cromwell-2.4 and a xbox-1.0.
i attached a wireless usb dongle (Bus 001 Device 003: ID 0ace:1215 ZyDAS
WLA-54L WiFi) to xbox. when it boots cromwell-2.4 bios, it freezes post
detecting hd and cdrom.
if i boot with usb dongle not connected, it boots normally.
do i've include something (or exclude usb detect process in cromwell)?

i've downloaded cvs tree and i've built it with a chroot ambient for
debian lenny i386 (gcc-3.4). i've loaded 2.41-dev into xbox but problem seems to be
present also.

waiting your response,
best regards.

- Dimitri

XIR Support on 2.6.x kernels

2008-12-10T20:19:03Z

Has anybody ported the xir.c USB DVD remote driver to work with a 2.6 era kernel? If so, could you send me the patch or zipped source files?

Thanks,
Brian

xpad driver digital trigger buttons

2008-10-04T21:36:25Z

Hello,
I was wondering why the xpad trigger buttons don't have digital
mappings like some of the other buttons?I added BTN_TL and BTN_TR and it
seems to work alright so I why aren't these in there by default?
btw great driver, very handy.

The floating-point calculations are probably there just because setting
up the video encoder is hairy business and it was the easiest way to go
forward with trying to get control of the thing. Those who last touched
the code were probably just glad to get it working and obviously lost
the interest in optimizing the calculations once the pieces fell in
place.

In order to understand the Conexant CX25871 calculations, you need to
read the data sheet / programming documentation. This document has been
available from Conexant as a free download - a PDF file. However,
Conexant seems to have reorganized their site (again), and I couldn't
find the document now. You can get it from me, though, if you need it.

Re: Mad Catz Beat Pad not recognized in xpad ver 0.1.7

2008-03-07T11:06:10Z

I've done some additional digging and where it fails below

usb_fill_int_urb(xpad->irq_in, udev,
usb_rcvintpipe(udev, ep_irq_in->bEndpointAddress),
xpad->idata, XPAD_PKT_LEN, xpad_irq_in,
xpad, ep_irq_in->bInterval);

I've added in some test code (diff below) just before it. The code bails if
ep_irq_in is NULL (undefined):

@@ -554,6 +556,13 @@

/* init input URB for USB INT transfer from device */
ep_irq_in = &intf->cur_altsetting->endpoint[0].desc;
+
+ // Testing for valid input
+ if (!ep_irq_in) {
+ info("ep_irq_in undefined");
+ goto fail2;
+ }
+
usb_fill_int_urb(xpad->irq_in, udev,
usb_rcvintpipe(udev, ep_irq_in->bEndpointAddress),
xpad->idata, XPAD_PKT_LEN, xpad_irq_in,

As you can see in the dmesg output below:

[ 104.270277] input: Mad Catz Beat Pad

It appears that the call to "ep_irq_in =
&intf->cur_altsetting->endpoint[0].desc;" is returning NULL is not caught by
the code. Therefore it crashes.

I guess there's some additional checking and logic that needs to occur there,
though I am at a loss as to exactly what needs to be done.

Suggestions?

Mad Catz Beat Pad not recognized in xpad ver 0.1.7

2008-03-07T10:11:34Z

I have an unrecognized controller. It's a Mad Catz Beat Pad.

I have modified the xpad.c (from version 0.1.7 in CVS) to attempt to support
this controller. No luck. I can get it to start and perform the xpad_probe,
at which point it picks up the inputs (3 of them) and then promptly causes
the kernel to OOPS with a NULL reference.

Here's the diff of my change:

I have tried this on two different systems with two different kernels. This
system is Hardy Heron (latest development release from Ubuntu) running kernel
2.6.24. I also tried it on my wifes system, which is Gutsy Gibbon (7.10
Ubuntu) running kernel 2.6.22. Both exhibit the same problem.

If I do not apply the patch, the controller is not picked up. Is there some
default thing I can test here?

If only apply "{ 0x0738, 0x4740, "Mad Catz Beat Pad", GAMEPAD_XBOX_MAT },",
then it is still not picked up.

Anything you can do to assist would be greatly appreciated.

Also, it appears as though this driver is not updated into later kernels. The
default in 2.6.24 is version 0.0.6 where it should be 0.1.7 (seeing as it's
been 9 months since that version was released). Do you pass this along to
upstream kernel?

I've attmpted to isolate exactly where in the code it fails. After some
further debugging, i'vediscovered that it succesfully gets input 10, 11 and
12 (3 successive calls to xpad_probe), it then attmpts to get the next input
and fails (this is the fourth call to xpad_probe).

It crashes here in the code:

usb_fill_int_urb(xpad->irq_in, udev,
usb_rcvintpipe(udev, ep_irq_in->bEndpointAddress),
xpad->idata, XPAD_PKT_LEN, xpad_irq_in,
xpad, ep_irq_in->bInterval);

I'm not sure I can offer any additional assistance, as I am not familiar with
the code nor the intent, only that for some reason this causes a NULL
reference and crashes the kernel, but only on the fourth iteration. Perhaps
one of the parameters to the call to usb_fill_int_urb is being passed a NULL
or some other invalid value causing usb_int_fill_urb to fail.

I am willing to assist further in debugging, just let me know what to test.

Cheers,

Rod.

etherboot xromwell?

2008-02-02T05:22:14Z

I just downloaded today's CVS and built it in an attempt to get
etherboot going. I have not been able to get xromwell to etherboot in
either 2.40 (release) or 2.41-dev Feb 2. The former tries forever to
get an address via DHCP, which works fine everywhere but here. The
latter hangs while trying to display the first icon, or so it appears.
I'm not sure how to debug that.

Had to add -fno-stack-protector (IIRC) to the CFLAGS for etherboot to
get it to build at all.

Built on Ubuntu Gutsy...

Does anyone have a working etherbooting xromwell xbe? Does such a
thing exist? I haven't really heard of anyone with an unmodified
cromwell successfully etherbooting anything, but I've seen lots of
complaints about it not working... Do I just need to build it with an
antique GCC or something?

Elisa is very nice, but it currently needs 3d hardware to work properly (otherwise it's just too slow), and afaik there's no 3d on linux on the xbox. (I think it's possible, tough, now that the nouveau project exists to add support for the nvidia graphics chip that the xbox uses.)

Re: kernel 2.4.35 and feisty = xUbuntu?

2007-08-04T11:27:25Z

Hi,

The distro xUbuntu is not simply a version of XUbuntu.
Because xUbuntu is worked out of a console version.
Then the graphical environment was activated.
To get a small desktop environment packages of all repositories was
integrated.
Mr. Hucek created the distro Xebian as a live disk and so did I.

Then Ubuntu community adopted the conception of live disk to dapper and
feisty.

So you may think, xUbuntu (with kernel 2.4.32) uses feisty packages.

----------

The founders of xbox-linux installed successfully linux on xbox360 and
closed development for first Xbox.

I developed xUbuntu (Ubuntu Dapper) for myself with a kernel 2.6.16-20-xbox
and never published it. The fatx driver works with kernel 2.6.18 but not
with newer kernels.

Mr. Hucek created mactel-linux. This way it is possible to upgrade my new
xUbuntu (kernel 2.6.16-20) with a mactel-kernel to feisty.
But I believe Mr. Hucek will not be very amused.

Ciao.

just thinking about how often I use the driver and realized I have never
used it
what would take to convert to 2.6 then?

It all depends on which distro you are running. As of Ubuntu feisty, you
can only use a 2.6 kernel.

No. It hasn't been updated in a long while.

Unfortunately, since recent versions of Ubuntu only work with 2.6,
nothing has really been done to make an up to date Ubuntu disc, as
2.4 is the only kernel that has a good FATX filesystem driver.

To answer my own question:
a) the kernel isn't supposed to use floating point calculations

b) we DO use floating point in drivers/video/xbox/conexant.c

Now if all the other screen drivers can figure out the parameters w/o
floating point calcuations, why does the XBOX chip need such tricks?
First, all screen dimensions are integer in the first place. Second,
even things like clock rates, etc. can be made integer by getting the
proper unit e.g. 0.3 seconds are 300ms.

If the code were a bit more readable/documented, then I'd take it
upon myself to convert that into integer math, but given the
potential to fry screens and graphic chips with the wrong data in the
registers, that's not something I want to debug without having a
clear understanding of what is supposed to be going on. :)

The amount and kind of math done in floating point seems trivial, but
it's not clear to me what precision is required and what some of
these parameters mean, because fields in some structs are not
documented, etc.

Any takers for either explaining me the details or converting this to
integer math? It seems odd that for one such module we run afoul of
the rules.

Xbox Linux kernel for 2.6.21-rc2 working too

2007-03-03T10:21:56Z

Subject says it all.

One question, though, that I don't get. In the kernel configuration's
"Processor type and features" section, the "Math emulation" help
states this:

So if Linux automatically uses a math processor, if present, unless
told to do so otherwise, then why on the one hand does the arch/i386/
Makefile specify in the standard kernel the -msoft-float compiler
flag, and why do we bother removing it for the xbox if the standard
kernel decides it's important to have that option?

I mean, either the kernel does the right thing, even with this
option, and uses the coprocessor if present, or it doesn't. Somehow,
this seems somewhat contradictory to me.

I then googled on the subject, and found this here:

http://uwsg.iu.edu/hypermail/linux/kernel/0409.1/2266.html

So does this mean the kernel is not supposed to use floating point at
all, and the -msoft-float forces the compiled to create references to
libraries, which then aren't linked and hence cause a link error to
catch this problem?

If so, shouldn't we stop patching this, and leave the -msoft-float
compiler flag where it is and reduce the size of the xbox-linux
kernel patch a bit?

Re: Xbox Linux kernel for 2.6.20.1 working (sort of...)

2007-03-02T10:59:48Z

OK, my quest for fairly universal, modular kernel has been reasonably
successful.
I now have a 2.6.20.1 kernel working that has modular support for
just about anything one might want to run on an XBOX or use the XBOX
to do development work on.
Only actual hardware drivers have not been compiled into modules,
because there are so many, and some seem to result in an unbootable
kernel and if I wanted to try which, I'd still be running compile
cycles for the next three months. Most subsystems however seem to
work, e.g. if anyone wants to play with ATM, they can use the ATM
over ethernet module and know the basic infrastructure is in the
kernel. For some that's overkill, for me it's just an insurance that
I don't have to keep dealing with the kernel itself, except if
there's significant upgrade.

The two stumbling blocks I found are the APIC setting
( CONFIG_X86_UP_API ) as mentioned previously. It claims to be
harmless, but for some reason on the XBOX it is not.

The other is the fact that FATX seems to be dependent on NOT having
CONFIG_LBD set. Interestingly enough, though, having CONFIG_LSF set
doesn't seem to be a problem.
It seems odd, though, that a modular file system would depend on the
system's ability to deal with large volumes. Just because that file
system cannot address that large a volume shouldn't mean that the
rest of the system and other file systems should not be able to do
so. Even more curious: the FAT file system code, on which FATX is
based, does NOT have that restriction.

So do we REALLY need that restriction of not having CONFIG_LBD set?

Otherwise, if someone tells me where I can upload the source and
kernel rpms along with the patch and config file, then I'm pretty
much ready to share the results if anyone is interested.

That may well be true. However, at least according to the make
menuconfig option help, this should (and likely is in non-XBOX
configurations) a safe option to select, and the kernel should just
ignore it at run time when the CPU doesn't support the feature.

Depending on which precise version of the kernel source you have, it
basically says "when in doubt, select this option" because the kernel
will just ignore it if the CPU doesn't support the feature and will
run w/o slowdown if the option is selected.

However, something about the XBOX prevents the system from booting
when the option is selected. So ideally, either the option should not
be selectable if the XBOX subarchitecture is selected, or the code
needs to be fixed somehow, such that the option behaves as benignly
on an XBOX as it supposedly behaves on other PC platforms.

Unfortunately I know way too little about the linux kernel to attempt
fixing this.

This option is only needed if the Xbox's CPU supports apic. Have a look
at /proc/cpuinfo. If apic is not mentioned in the flags, this option can
remain deselected.

I think that the PIII CPUs don't support this option, unless they are
used in an SMP configuration.

Hi,

I have been able to eliminate a lot of potential sources for the
unbootable kernel.

I have found one culprit however (there may be more, I'm still testing).
The one known problematic kernel option is this one:

> Location: -> Processor type and features

From the description, this seemed like a perfectly OK option to
select. Somehow, it seems, the XBOX doesn't like it at all.

Either the dependencies of that option should make it unavailable
when the XBOX architecture is selected, or we need some additional
bug fixes somewhere that do whatever's needed that this behaves
properly.
My (lack of) knowledge of the kernel prevents me however from dealing
with this issue, so for now I continue with this option deselected,
to see if there are other options that have similar effects.

Thanks for the offer. *RIGHT NOW* I don't need the Xbox 360
controller. So for myself it's not much of an issue, particularly
since I'm not a game player, but I hope to make my 2.6.20.1 patches
available once things work smoothly, so others can use it, too.

So the issue is much more how to get a definitive version of that
code, particularly since the xpad driver is also in the standard
Linux kernel distribution, so changes really should be pushed
upstream. The less patches we need to do an xbox kernel, and the more
we can push into the regular kernel sources, the better.

Maybe if you have the time, you could compare the state of affairs in
the 2.6.20.1 source tree, and what's on the xbox-linux sourceforge
site, add whatever may be missing from your patches and the xbox-
linux version into the official version, and propagate it to the
kernel maintainers. That way we can then hopefully just get
completely rid of a separately maintained xpad driver.

Greetings,

Ronald

My patch only has stuff for the Xbox360 controller. I can update it if
you need to use it.

Xbox Linux kernel for 2.6.20.1 working (sort of...)

2007-02-25T22:21:15Z

Hi,

I have a bootable kernel for 2.6.20.1 kernel. Of course, I have no
idea if/how well the FATX support will crash the system, but at least
it will compile, and thus hopefully entice someone who knows what
he's doing to fix it eventually ;-)

I have however another problem: I tried to configure that's as
universally useful as possible w/o sacrificing XBOX bootability. The
only way I get a bootable kernel though is if I use the 2.6.18-fc6
xbox kernel, and then do a make oldconfig.

However, the moment I try to make a slightly more universally useful
kernel by enabling a few options that seem like they might come in
handy at some point or another, the kernel won't boot anymore.

Now, since each option change and compile install, and rescue boot
and revert cycle takes several hours, it's extremely unpractical the
enable options one-by one, or to try to narrow down which option(s)
it is exactly that make the kernel not boot.

So what I wonder is if any of you had similar experiences when you
compiled an xbox kernel. If you know/remember any option that you
tried that made the kernel not boot, I'd be very interested in
knowing which because maybe it's as simple as deselecting a few known
bad options to achieve what I want with the rest.

Greetings,

Ronald

Hi,

thanks. Unfortunately, this patch seems to create more questions than
it solves ;-)

Since most of the xbox kernel patches I could find were rather old
and wouldn't cleanly patch, I followed the instructions found here:
http://www.phoronix.net/forums/showthread.php?p=4445
and use the files found here:
http://xbox-linux.cvs.sourceforge.net/*checkout*/xbox-linux/
kernel-2.6/drivers/usb/input/xpad.c
http://xbox-linux.cvs.sourceforge.net/*checkout*/xbox-linux/
kernel-2.6/drivers/usb/input/xpad.h
with minor changes as the post there describes:

except instead of commenting out, I just deleted the corresponding
lines, since there's no point to carry old code in the source for a
new version of the kernel.

The problem is, the patch doesn't work with these versions of the
files, and now I don't know if I work with files that are
a) too new
b) too old
c) from a totally different, incompatible branch
for the patch to work.

If the sources I use are newer, then is the functionality of the
patch already in there?
If the sources I use are older, then were is a more up to date
version of the xpad.c to be found to which I can apply the patch?
If the sources I use are from a separate source branch, then which
should I use and why, and why do we have more than one branch in the
first place?

Just trying to get the cleanest (most applicable patches applied) and
newest kernel running on an XBoX such that I have a good basis from
which to work forward, but it's not like I know anything about xpad
device drivers...

Stupid noob question: where can I get old messages from this list in raw format?

2007-02-24T16:28:09Z

Hi,

I'm trying to apply the xpad.c patch posted on this list back in 5
October 2006 by Matt.
All the list archives seem to be web based, and I can't download a
raw patch file (or copy/paste in a useful way) the patch as displayed
by the various web interfaces and web archives of the list.

Also, why isn't a patch like this reflected in the current source or
available on the files list on sourceforge.

I'm currently in the process of trying to get a 2.6.21-rc1 kernel
running (2.6.20.1 is already working), but getting all the latest
patches into the code is a major PITA because they are not collected
in a central location from what I can tell.

Any hints/help appreciated.

Ronald

Re: Nouveau nvidia oss driver

I basically just packaged the CVS code for Debian; it's at:
http://www.cs.cmu.edu/~ecc/xserver-xorg-video-nvxbox_1.0.1.5_i386.deb
.../xserver-xorg-video-nvxbox_1.0.1.5.dsc
.../xserver-xorg-video-nvxbox_1.0.1.5.tar.gz
It may need to be updated again for the latest xserver-xorg -- if anybody does
that, please let me know so I can track the changes.

I'm also interested in nouveau for Xbox -- lack of 3D made me ditch my
Xbox-based MythTV frontend because I wanted to run StepMania as well.
But I'm not likely to work on it any time soon, since the little PC
I'm using now is a lot faster, quieter, and smaller than the Xbox.

Hi,

there seems to be new binary driver for Xorg created by Eric Cooper.
Search in Newsgroup users for modular nvxbox driver.

Nouveau nvidia oss driver

2007-01-09T09:03:57Z

In the last few months a project has formed to advance the nv driver with better support and open-source 3d. Would it be feasible to run in on the xbox? Has anyone looked into it?

I've been looking at the CVS and this http://xbox.cvs.sourceforge.net/xbox-linux/xf86-video-nvxbox/ seems to be the latest version of the X driver for the xbox. Am I correct?

vdr client

2007-01-06T05:48:53Z

Hi everyone,

I'm discovering the joys of running linux on my xbox. My plan is to
have a vdr streaming client setup which can perform all the regular
functions of a normal vdr client - ie pause/rewind live TV, initiate
recordings on the server, view recordings, administer vdr-burn plugin
to backup to dvd-iso, and if possible check an imap account for emails
and display them on the OSD.

I would like to have a full featured client like this in a loopback
file system, so that I can launch the mini-distro from within xbmc.
This setup needs to have a fairly high WAF..

Currently I'm playing with a xebian distro built in 2005, vdr version
is alot older than my server and I'm only just breaking the surface
of it. I can view some liveTV and intiate recordings but not view them
on the client.
My first plan is install the apt .deb package and try and update vdr.

I'm just wondering if theres anyone who is also using this setup, how
well you got it working, specific problems that the xbox gives etc..

Thanks

I changed the settings to only let members post.

Sorry for the problems in the past.

Re: All the spam on xbox-linux

2006-11-05T13:06:51Z

Perhaps gmail automatically whitelists the mailing-list's email
address if you have ever sent it an e-mail (since all the spam comes
from the xbox-linux-devel e-mail address).

Please, someone alter the list so that it's better, or we should all
just leave and make a new one.
