Summary: BUG: Display gets corrupted when using lxfb driver on a
GeodeLX 5535 based chipset
Product: Drivers
Version: 2.5
KernelVersion: 2.6.24.2
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Console/Framebuffers
AssignedTo: jsimmons@infradead.org
ReportedBy: nestorac@gmail.com
Latest working kernel version:
None or unknown
Earliest failing kernel version:
Latest version
Distribution:
Debian Stable (Etch)
Hardware Environment:
AMD Geode 32 bit A830 board, 5536 chipset based embedded computer (TFT 10"
800x600), with GeodeLX embedded GPU. It's webpage is at:
http://www.winmatev.com.tw/PPc/PPcSpec.asp?Prod=03_0013&Typeid=03020101
I own a cheaper version using GeodeGX 500 processor, 256MiB RAM, no
touchscreen.
Software Environment:
Debian 4.0 Stable (Etch), Kernel 2.4.22.2 vanilla + AUFS patch (it has nothing
to do with graphics, but BTW...), all i386, kernel specifically compiled for
Geode GX/LX Processor target (but also does not work for generic i386 target).
Problem Description:
I get a blurry screen when trying to enable Framebuffer, vga=788
option (800x600). Screen gets corrupted, but when I start X.org, it shows
Ok, until I switch again to console. Everything works fine with Vesa FB,
except that, of course, it's more CPU consuming and slower [supposedly].
When blurry, screen looks like it was under a lake.
Steps to reproduce:
1) Compile the kernel, include support for GeodeLX Framebuffer.
2) Install the kernel on the machine
3) Boot it up, adding vga=788 mode to bootloader.
4) Screen gets completely blurry until X.org starts.
Guys, this is a post-2.6.24 regression hence needs
running-around-with-your-hair-on-fire priority please.
Can anyone think what we did to cause this? Recent changes to
drivers/video/geode/ look pretty tame.

Hm, what exactly makes you think so?
The failing kernel version is 2.6.24.2, so most probably the problem is present
in 2.6.24 as well.
Moreover, the reporter didn't specify the last known good kernel, so it might
not be a regression at all.

Beats me. I was probably looking at the wrong report when I decided that.
The failing kernel version is 2.6.24.2, so most probably the problem is present
in 2.6.24 as well.

Yup.
