ASpeed Technologies KMS VGA Driver error in log

[Keven]

1. ASpeed Technologies KMS VGA Driver error in log
2. Hi, I have an error message in my kernel log and I don't know if this
need to be taken care of or this is a normal behaviour. 

The component is [PATCH] drm: Initial KMS driver for AST (ASpeed
Technologies) 2000 series
This article is related to the new compoent. 
http://lists.freedesktop.org/archives/dri-devel/2012-April/021578.html

The code file should be 
Linux/drivers/gpu/drm/ast/ast_mode.c

The error I have is  
[    7.518793] [drm:ast_cursor_init] *ERROR* pinned cursor cache at 0

When I start my machine, I receive these messages from the component.

[    7.515770] ast 0000:01:01.0: enabling device (0000 -> 0003)
[    7.516711] [drm] AST 1100 detected
[    7.516764] [drm] dram 324000000 0 32 04000000
**
[    7.518793] [drm:ast_cursor_init] *ERROR* pinned cursor cache at 0
**
[   23.703894] fb1: astdrmfb frame buffer device
[   23.703897] drm: registered panic notifier
[   23.703902] [drm] Initialized ast 0.1.0 20120228 for 0000:01:01.0 on
minor 0



This can be traced back to the function
int ast_cursor_init(struct drm_device *dev)
and 
	DRM_ERROR("pinned cursor cache at %llx\n", ast->cursor_cache_gpu_addr);

So.. is this normal ? ? ?

Also, I do *not* use the inboard graphical card. I plugged an external
card in the pci-express slow on this board. There is no options in the
bios to deactive the external card and check if the message is
different. As I am using another card, the system does work.

Please advise.

Oh thanks for pointing this out, its just left over debug, I'll send a patch
to remove it.

Hello, 
I see no changes in the current kernel tree. Maybe you forgot about
it ?

Not sure what kernel tree you are looking in, should be in Linus tree upstream now.
