[Mesa-dev] freedreno: 'Unhandled NIR tex src type: 11' on A3XX

[Brian Masney]

Hi,

I'm trying to get the GPU working using the Freedreno driver (A330) on
the Nexus 5 phone. I'm using kernel 5.2rc3 with some out of tree patches
related to the GPU [1] and mesa 19.1.0-rc5 on postmarketOS. When I run
glxgears, I see the gears show up for a fraction of a second and then
it terminates due to the following error:

-----

decl_var uniform INTERP_MODE_NONE sampler2D sampler (0, 0, 0)

        /* preds: */
        vec1 32 ssa_0 = load_const (0x00000000 /* 0.000000 */)
        vec2 32 ssa_1 = intrinsic load_barycentric_pixel () (1) /* interp_mode=1 */
        vec4 32 ssa_2 = intrinsic load_interpolated_input (ssa_1, ssa_0) (0, 0) /* base=0 */ /* component=0 */  /* in_0 */
        vec1 32 ssa_3 = deref_var &sampler (uniform sampler2D) 
        vec2 32 ssa_4 = vec2 ssa_2.x, ssa_2.y
        vec4 32 ssa_5 = tex ssa_3 (texture_deref), ssa_3 (sampler_deref), ssa_4 (coord)
Unhandled NIR tex src type: 11

        block block_1:
}

Assertion failed: !"" (../src/freedreno/ir3/ir3_context.c: ir3_context_error: 407)

I verified that the mesa 19.1.0-rc5 release contains this recent a3xx
fix from Jonathan:
https://gitlab.freedesktop.org/mesa/mesa/commit/1db86d8b62860380c34af77ae62b019ed2376443

Any suggestions?

    The GPU specific patches start at Rob's patch 'qcom-scm: add support
    to restore secure config' on that list. I submitted the patches
    below that a few weeks ago to the upstream kernel and I expect
    they'll be merged. Once I have a working GPU, I plan to start
    working on the interconnect support in the kernel for msm8974 so
    that the clock hacks can be dropped.
