Bug ID: 111404
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 enumerating OpenCL platforms and devices with the clinfo command, I found
that OpenCL devices (AMD Radeon HD 8470) do not support OpenCL images.
I don't understand why this problem occurs. I don't even understand whether
this is a fault in the graphics card itself or the graphics card driver, or
ignore several options when compiling mesa.
