In px30, rkvdec and vdpu&vepu need set grf and ensure working in current hardware mode before running. this issue may accur when get iommu dte_addr, thus add set_grf before, then ensure the hardware working mode. refer log when probe: [ 3.040107][ T53] mpp_rkvdec ff440000.hevc: Adding to iommu group 1 [ 3.040455][ T53] mpp_rkvdec ff440000.hevc: probing start [ 3.040939][ T53] rkvdec_init:1139: failed on clk_get clk_cabac [ 3.040991][ T53] rkvdec_init:1142: failed on clk_get clk_hevc_cabac [ 3.041031][ T53] mpp_rkvdec ff440000.hevc: reset_group->rw_sem_on=0 [ 3.041057][ T53] mpp_rkvdec ff440000.hevc: reset_group->rw_sem_on=0 [ 3.041107][ T53] mpp_rkvdec ff440000.hevc: shared_video_cabac is not found!

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
