AGP speed not detected properly

Hi Gildo,

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

I have already tested Linux 2.6.27 on Intrepid Ibex but the result is the same

I point out a possible solution on bugzilla.kernel.org:

Sorry for my english

[Ermenegildo Fiorito (fiorito-g)]

From Albert Gall on bugzilla.kernel.org :

Hello:

With this version of the kernel

http://www.kernel.org/pub/linux/kernel/v2.6/testing/patch-2.6.27-rc5.bz2

and the following options enabled

Symbol: ACPI_PCI_SLOT [=]

Symbol: AMD_IOMMU [=]

seems that the problem is solved.

I would like to prove what someone else and comment on their results.

news?

[Leann Ogasawara (leannogasawara)]

Here's the current kernel config options for ACPI_PCI_SLOT and AMD_IOMMU for Intrepid. Looks like the latter isn't enabled for i386. I'll reassign to the kernel team. Thanks.

ogasawara@emiko:~/ubuntu-intrepid/debian/config$ grep -rn "ACPI_PCI_SLOT" *
amd64/config:45:CONFIG_ACPI_PCI_SLOT=m
i386/config:47:CONFIG_ACPI_PCI_SLOT=m
ogasawara@emiko:~/ubuntu-intrepid/debian/config$ grep -rn "AMD_IOMMU" *
amd64/config:96:CONFIG_AMD_IOMMU=y

[Andy Whitcroft (apw)]

The AMD_IOMMU symbol is not something one can enable for the i386 version of the kernel according to Kconfig:

config AMD_IOMMU
        bool "AMD IOMMU support"
        select SWIOTLB
        depends on X86_64 && PCI && ACPI

Also from the dmesg.log attached above, the agp gart seems to be found and configured ok:

[...]
[ 12.112178] Linux agpgart interface v0.103
[ 12.153706] agpgart: Detected AGP bridge 0
[ 12.154810] agpgart: AGP aperture is 32M @ 0xe4000000

[ 36.749635] agpgart: Putting AGP V3 device at 0000:01:00.0 into 8x mode

So its not clear turning on more gart support is the issue here. We can also see that your graphics card was picked up here (from your lspci output):

01:00.0 VGA compatible controller [0300]: ATI Technologies Inc RV280 [Radeon 9200 PRO] [1002:5960] (rev 01)

Now I do note that this does show the AGP aperture as 32MB, and from your Xorg.log, you seem to have configured it to be 64MB:

(==) RADEON(0): Default visual is TrueColor
(**) RADEON(0): Option "AGPMode" "8"
(**) RADEON(0): Option "GARTSize" "64"
[...]
(**) RADEON(0): Using AGP 8x

(EE) RADEON(0): [agp] Could not bind
(EE) RADEON(0): [agp] AGP failed to initialize. Disabling the DRI.

Can you check if this is a real option in your Xorg.conf configuration file, and if so try and disable that for the i386 boot?

Ermenegildo, not sure why you assigned this to me when Andy had already taken ownership. Please don't assign/reassign bugs to someone without asking first. Thanks.

Some update:
My Xorg working but not Compiz.

I have ATI Radeon 9600 with Pentium4 2.40 on unkown (to me) Motherboard.

I also check Fedora10 and it work fine. There are no xorg.conf in Fedora so I'm attaching Xorg.0.log file

[Wawrzyniec Niewodniczański (wawrzek)]

And Xorg.log from Ubuntu 8.10

This looks similar, the aperture allocated by the BIOS looks to be 16MB
but the card really wants 32MB so there simply is not space. This will
prevent DRI from initialising and that in turn stops compiz from being
used. You might want to check if there are any aperture options in your
BIOS and see if they let you make the space larger.

[Wawrzyniec Niewodniczański (wawrzek)]

I changed Aperture size to 32Mb in Bios and card started to work fine. Thank Andy!!!!

I think there is a problem with screen size in 'text mode'. I will try to explicit add some vga option to the kernel.

If you need any other test please let me know. Anyway I#'m going to try TV-Output next.

[Andy Whitcroft (apw)]

@Ermenegildo Fiorito -- we are still waiting to hear if you have an aperture defined in your xorg.conf. Also others have had success increasing their aperture size in their BIOS, see above. You should also check that and report back.

[Andy Whitcroft (apw)]

@Ermenegildo Fiorito -- could you comment on whether the bios change worked for you. If we do not hear back shortly we will assume that this was the trigger and close the bug. Thanks for your input.

[Ermenegildo Fiorito (fiorito-g)]

The bios change don't work for me

[Andy Whitcroft (apw)]

@Ermenegildo Fiorito -- ok could you attach the dmesg output and /var/log/Xorg.0.log logfile to this bug for me. Thanks!

[Andy Whitcroft (apw)]

 @Ermenegildo Fiorito -- we are still waiting for the dmesg output and /var/log/Xorg.0.log logfile to be attached to this bug for me. Thanks!

[oliver (oliver-schinagl)]

Almost 2010 and still seeing this bug. I'm running Karmic Koala with a 2.6.31-15-generic i386 kernel. I can't change (m)any setting in the bios, as this is an IBM T42 so an IBM bios with limited options.

The two important entries from lspci.
I dunno if it really matters that AGP is stuck in 1x mode, I forced it into agp 4x mode via my xorg.conf ages ago and it 'felt' smoother on the desktop, but that may be a placebo very well. Switching between virtual desktops is just doomed to be slow :p
