When I try to use the 3D, it returns some errors and the dmesg log shows some memory allocation errors too: [ 3.682347] etnaviv etnaviv: bound 130000.gpu (ops gpu_ops) [ 3.688669] etnaviv etnaviv: bound 134000.gpu (ops gpu_ops) [ 3.695099] etnaviv etnaviv: bound 2204000.gpu (ops gpu_ops) [ 3.700800] etnaviv-gpu 130000.gpu: model: GC2000, revision: 5108 [ 3.723013] etnaviv-gpu 130000.gpu: command buffer outside valid memory window [ 3.731308] etnaviv-gpu 134000.gpu: model: GC320, revision: 5007 [ 3.752437] etnaviv-gpu 134000.gpu: command buffer outside valid memory window [ 3.760583] etnaviv-gpu 2204000.gpu: model: GC355, revision: 1215 [ 3.766766] etnaviv-gpu 2204000.gpu: Ignoring GPU with VG and FE2.0 [ 3.776131] [drm] Initialized etnaviv 1.2.0 20151214 for etnaviv on minor 0 # glmark2-es2-drm Error creating gpu Error: eglCreateWindowSurface failed with error: 0x3009 Error: eglCreateWindowSurface failed with error: 0x3009 Error: CanvasGeneric: Invalid EGL state Error: main: Could not initialize canvas Before this patch: [ 3.691995] etnaviv etnaviv: bound 130000.gpu (ops gpu_ops) [ 3.698356] etnaviv etnaviv: bound 134000.gpu (ops gpu_ops) [ 3.704792] etnaviv etnaviv: bound 2204000.gpu (ops gpu_ops) [ 3.710488] etnaviv-gpu 130000.gpu: model: GC2000, revision: 5108 [ 3.733649] etnaviv-gpu 134000.gpu: model: GC320, revision: 5007 [ 3.756115] etnaviv-gpu 2204000.gpu: model: GC355, revision: 1215 [ 3.762250] etnaviv-gpu 2204000.gpu: Ignoring GPU with VG and FE2.0 [ 3.771432] [drm] Initialized etnaviv 1.2.0 20151214 for etnaviv on minor 0 and the 3D gemos work without this.
