[Linux-fbdev-devel] request_mem_region problem ...

[Sven L. <lu...@dp...>]

Hello, ...

I have begun porting pm3fb to the new api, well, more exactly i am
adapting tdfxfb to handle pm3 chips, and will port parts of pm3fb to it
as i need them.

I have a problem when loading pm3fb as a module, and that is that
request_mem_region fails. I know that pm3_fix.mmio_start and
pm3_fix.mmio_len are correct, but request_mem_region still fails.

I am still searching the definition of request_mem_region in the source,
but any help would be most welcome.

Note, this is with stock 2.5.44.

Also, if i register the framebuffer, without defining any of the
fillrect, copyarea and imageblit functions (even the generic ones) i
suppose it is normal i only get a black screen, isn't it ?

Friendly,

Sven Luther
