Bug ID: 106527 Summary: OpenCL corrupted memory on AMD R9 280X Product: DRI Version: XOrg git Hardware: Other OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu-pro Assignee: dri-devel@lists.freedesktop.org Reporter: riccardodemaria@gmail.com
I am trying to use the AMD R9 280X (Tahiti) with the latest Ubuntu 18.04 and AMDGPU-PRO driver.
OpenCL appears to work with
export GPU_FORCE_64BIT_PTR=1
see https://bugs.freedesktop.org/show_bug.cgi?id=102491
however the memory appears corrupted on the device resulting in random data populating partially or entirely the buffers.
A simple OpenCL program is sufficient to show the problem:

in my case.
