| Subject: [PATCH] intel: limit shader geometry on BDW GT1 |
| |
| Similar to the SKL GT1 fix introduced here: |
| |
| https://gitlab.freedesktop.org/asimiklit/mesa/commit/b1ba7ffdbd54fdb5da18d086c7b7a830e06a1cff |
| |
| we need to limit the .urb.max_entries[MESA_SHADER_GEOMETRY] on BDW GT1 |
| to address failures in these two tests: |
| |
| dEQP-GLES31.functional.geometry_shading.layered.render_with_default_layer_3d |
| dEQP-GLES31.functional.geometry_shading.layered.render_with_default_layer_2d_array |
| |
| The value 690 was found via bisection. 691 is the actual max on the |
| hardware I'm using, but 690 seemed like a nice round number. |
