Nouveau - Oct 2011 - NVIDIA (including Optimus) laptop owners - please read!

Hi guys and gals,

I'm working on improving nouveau's support for MXM (Mobile PCI Express
Module) chips and need some more data to check my implementation.

To see if you can help, the first thing to do is jump over
to /sys/firmware/acpi/tables and run "grep MXMS *".

[root at nisroch tables]# grep MXMS *
Binary file DSDT matches
[root at nisroch tables]# 

If this isn't present, while running nouveau, using i2c-tools (fedora
package name) do the following as root:

modprobe i2c-dev
i2cdetect -l

Any you should see something like:

[root at nisroch ~]# i2cdetect -l
i2c-0	smbus     	SMBus I801 adapter at 1860 SMBus adapter
i2c-1	i2c       	nouveau-0000:01:00.0-2     I2C adapter
i2c-2	i2c       	nouveau-0000:01:00.0-0     I2C adapter
i2c-3	i2c       	nouveau-0000:01:00.0-10    I2C adapter
i2c-4	i2c       	nouveau-0000:01:00.0-6     I2C adapter
i2c-5	i2c       	nouveau-0000:01:00.0-11    I2C adapter
i2c-6	i2c       	nouveau-0000:01:00.0-12    I2C adapter
i2c-7	i2c       	nouveau-0000:01:00.0-8     I2C adapter

For every nouveau entry there, run "i2cdetect <bus>" (where
number is
the i2c-<bus> in the above list).  If you see 0x54 or 0x56 appear on any
of the i2c busses, please save the output of "i2cdump <bus>
<address>",
where <address> is 0x54 or 0x56 (whichever appears).

If you either the above is present, it would be a great help if you
could email the matching files along with a number of different vbios
images to mmio.dumps at gmail.com.

Now, onto the different vbios images.  To obtain these, install
envytools[1] and run the following:

nvagetbios -S PRAMIN > vbios_pramin.rom
nvagetbios -s PROM > vbios_prom.rom

If fetching the VBIOS from PROM fails with (for example):

[root at nisroch tables]# nvagetbios -s PROM >vbios.rom
Attempt to extract the vbios from card 0 (nva8) using PROM
Invalid signature(0x55aa). You may want to try another retrieval method.
[root at nisroch tables]# 

Then it's possible that we need to fetch it from ACPI instead.  The
easiest way is probably to reboot with "nouveau.vbios=ACPI" in your
kernel options, and then:

mount -t debugfs debugfs /sys/kernel/debug
cp /sys/kernel/debug/dri/0/vbios.rom ~/

Any questions, feel free to respond to this email or jump into #nouveau
on freenode and ping me (darktama).

Thanks in advance!
Ben.

I have two i2c devices for my nvc3 (555M) on Optimus: 15 and 16. 
But when I probe both, there's no occupied addresses. 
Is this normal?

Also, I don't think any Optimus laptops feature MXM cards. 
I can only assume that the Optimus versions of the 460M, 
560M, and 570M are fixed to the motherboard.

There are some Optimus laptops with the MXMX and MXDS ACPI calls, 
but they aren't MXM. 90% of Optimus laptops are _DSM.

Hello,
I have an Asus U36SD with nvidia optimus technology.
OS is Fedora 15 + virt-preview repo. I have also win7 installed in
another partition.
I have the default nouveau drivers installed.

Let me know if you need further info.

Ben, most Optimus laptops have no physical output for the Nvidia GPU. 
Oddballs like the Dell XPS line have the HDMI ports connected to the GPU 
and Asus laptops have the MXDS/MXMX mux for the LVDS.

Come to the #bumblebee-dev channel on Freenode if you want any 
additional resources. We're eager to help.

i2cdetect output has both 0x54 and 0x56. But I've stuck on getting vbios
images.
# nvagetbios -s PROM >vbios.rom

gives me the error you've mentioned:
> Attempt to extract the vbios from card 0 (nv86) using PROM
> Invalid signature(0x55aa). You may want to try another retrieval method.
>
and adding string (without quotes) "nouveau.vbios=ACPI" to kernel
options
doesn't work at all. GRUB2 shows me error:
> alloc magic is broken at 0xdfbdbc50
> Aborted. Press any key to exit.

Nouveau already works MUCH better than proprietary driver for my tasks.
Thanks a lot for that! Please help me to help you.

My system info:

   - Debian testing/unstable
   - kernel 3.0.0-1-686-pae from repository
   - libdrm-nouveau1a 2.4.26-1
   - xserver-xorg-video-nouveau 1:0.0.16+git20110411+8378443-1+exp1
