| Subject: [PATCH] virgl: support emulating planar image sampling |
| |
| Mesa emulates planar format sampling with per-plane samplers. Virgl now |
| supports this by allowing the plane index to be passed when creating a |
| sampler view from a planar image. With this change, mesa now passes that |
| information to virgl. |
