Bug ID: 93466
Summary: [r600g] Emulate fp64 OpenCL operations using integer
arithmetic
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW
Severity: enhancement
Priority: medium
Component: Drivers/Gallium/r600
Assignee: dri-devel at lists.freedesktop.org
Reporter: rivanvx at gmail.com
QA Contact: dri-devel at lists.freedesktop.org
For teaching and demonstration purposes it would be cool to have emulated fp64
arithmetic on low-end Evergreen and Northern Islands chips which don't support
it (e.g. Caicos). However slow it might end up being, it would be really useful
to have it at least for teaching GPU computing.
