Hi Arnd,

Thanks for you advice.

Because this is very emergency for customers and have delayed for monthes,

and the

quoted

DRM/KMS will have a little long time to be supported. So I'd like to add

this first

quoted

and will add DRM/KMS version later.

I would also suggest to just write a drm driver for this. I don't see
anything special in this driver that would be better supported via
fbdev. With drm you'll get a more modern framework, and you will still
have the same /dev/fbX device to use for legacy userspace software.

What do you mean with "delayed for months"? The first version of this
series (that I can find) was posted less than two weeks ago.

Sorry for confusing, it was delayed for other reasons internal.

I am not familiar about the DRM, and I'd like to know if the DRM driver will be
support, should I also develop the libdrm too ? Or just coding in kernel level ?
Is there any Document about how to have /dev/fbX device to use ?

If possible, I'd like this could be accept for this time. And I will add the DRM
Version later(for developing and testing will take a long time).

Thanks very much,

BRs
