Hello all,
I need to remap 1 page from user space to kernel and I use get_user_pages_remote for this purpose
ret = get_user_pages_remote(tsk, tsk->mm, offset, 1,
0,
&pinned_page, NULL);
Kernel is 4.9.88
I compiled module for Arm Vertex board and run it under QEMU with no problem
But on Android 9 with this exactly kernel I got Oops:
Unable to handle kernel paging request at virtual address fe002000
pgd = d8c14000
[fe002000] *pgd=00000000
Internal error: Oops: 5 [#1] PREEMPT SMP ARM
I checked config files and did not find any difference( almost except balloon ) in memory related configs.
Does anybody have a clue what is a problem here?
Regards,
Lev
