drm_gem_mmap failing!

[Vikas Patil <vikasmpatil@xxxxxxxxx>]

Hi All,

 

I am running the webkit on custom linux based on 3.4.25 kernel on omap5. However it is failing to map some memory using drm_gem_mmap() at following code.

 

 

if (map->size < vma->vm_end - vma->vm_start) {

                                ret = -EINVAL;

                                goto out_unlock;

                }

 

Here is one of the failing params

vma->vm_pgoff = 170254

map->size:73728

 vma->vm_end = 1776594944

 vma->vm_start:1776463872

 (vm_end - vm_start):131072

 

Could anyone please suggest how to debug this or Is this a known bug?

 

Regards,

Vikas
