Tiny Core 8 with Intel HD Graphics 500 on Intel Atom E3930 CPU

[dspence]

Hi all,

I'm having trouble getting Tiny Core 8 to work on a new machine that has an Intel Atom E3930 CPU, with integrated HD Graphics 500.  lspci identifies the graphics as "Intel Corporation Device 5a85 (rev 0b)".

I want to run Xvesa on it, but it reports "Interrupt pointer (seg d0 off 20) doesn't point at ROM" four times, before reporting "Fatal server error: no screens found", followed by a segmentation fault.

I have also tried Xorg.  I installed that with libva-intel-driver.tcz, xf86-video-intel.tcz, and also firmware-i915.tcz, and from /var/log/messages and /var/log/Xorg.0.log, it looked like it was working, but I only had a black screen.

Xvesa is really the one I want to have working, though.

Has anyone managed to get Tiny Core 8 to work with graphics on this chip?  Any help would be appreciated.

Thanks.

You have a third option, framebuffer and Xfbdev. Please see the FAQ for samples of the vga= bootcode.

[dspence]

Thank you, curaga!  Xfbdev works!  It even seems fast on this hardware!

[dspence]

Just an update: I got Xorg to work and I've decided to continue with that, for reasons of performance and compatibility with other, older Atom CPUs with integrated graphics.

Thank you again!

Hi dspence
If it could help someone else with hardware similar to yours, maybe you could post some hints on what they need to do.

Hi Rich,

There was really no issue with Xorg on this hardware.  There was a syntax error before the call to 'waitforX', caused by the automatic removal of three conditional calls to Xvesa with different screen resolutions.

I think that Xvesa won't run because this machine has UEFI with no Compatibility Support Module.

I did have an issue with Xorg on some older hardware, with Intel Atom N2600, Z530, and Z510 that looked like this in Xorg.0.log:

...

This was solved by removing libva-intel-driver.tcz from onboot.lst.  The Illegal Instruction seems to be coming from file /usr/local/lib/dri/kms_swrast_dri.so in the Xorg-7.7-3d.tcz extension.

[Juanito]

as per the Xorg-7.7-3d info file:

*** minimum cpu pentium-m ***

[curaga]

Those Atoms are above pentium-m, so maybe another compiler/build process bug.

[coreplayer2]

This could all be outdated info, but AFAICT  the Xorg Intel driver does not appear to support the 500 series graphics chip used in many Atom based computers.
https://www.x.org/wiki/IntelGraphicsDriver/

This apparently is the list of currently supported Intel graphics chips
https://www.x.org/wiki/IntelLaptopChips/

On the positive side Intel has released a driver "Intel Embedded Graphic Driver" for linux which supports these graphics chipsets....    but i'm still looking for that. 

[dspence]

Okay, there are still issues on the machine with the Intel Atom E3930 CPU with integrated HD Graphics 500.  Overall it seems to work fine, but when I connected using x11vnc, opened a terminal (aterm) and scrolled, the image was corrupted.

After trying a bunch of different things (various arguments to x11vnc, a different VNC server, an older version of aterm) I then tried grabber.tcz to get a screen grab of what was displayed on the screen (as opposed to what I saw with VNC) and the same thing happened with grabber.

I have attached a couple of files to this message.
1. File camera.jpg is what I see on the screen.
2. File grabber.png is what is grabbed with the grabber program.  This is the same as what appears when connected using x11vnc and x0vncserver.

Using the exact same software, this corruption does not happen when using older hardware with Atom N2600 or Z530.

So yeah, maybe the Xorg Intel driver doesn't fully support this chip yet. :-/

[Juanito]

What happens with the xorg-server modesetting driver (i.e. don't load the intel driver)?

[curaga]

IIRC the same was seen in vmware, and there the user decided to use another terminal instead of aterm.

[dspence]

Hi Juanito,

So I removed xf86-video-intel.tcz from onboot.lst, and rebooted.

I ended up at "failed in waitforX".

Hi curaga,

I will try another terminal and post the results.  Thanks for the suggestion.

Edit:
So I tried lxterminal.tcz.  It does not show the same bad behaviour as aterm, but I can't use it for other reasons.

The gnome-terminal.tcz extension also doesn't display the bad behaviour as aterm.  It has other bad points (and btw it is missing dependency libffi5.tcz, but even after providing that it won't launch from the icon on wbar.  I had to launch it using sudo, from aterm.)

I will look for other terminals to try.

Hi dspence

I will look for other terminals to try.

Maybe rxvt?
