Bug ID: 111403
Summary: OpenCL device doesn't support "Image support"
Product: Mesa
Version: 18.0
Hardware: Other
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Other
Assignee: mesa-dev at lists.freedesktop.org

when running clinfo command on my platform, I noticed OpenCL Device(ADM
Radeon HD8470) doesn't support "Image Support".
As a beginner, I don't know why such a problem occurred. It's whether a
fault which about AMD HD8470 Device or Video Driver on my platform, or I was
ever neglect some compiling options when build mesa(packages such as
mesa-libOpenCL/mesa-libOpenCL-devel come from mesa source rpm package ).
Information about my platfom as follows：

Anyone can give some hints about this problem? The following links shows AMD
HD8470 Device support OpenCL 1.2.

If the problem can't be solved via software path, Maybe the best choice is
changing OpenCL Device or Platform.
