Description Craig Stout 2018-04-11 22:48:23 UTC
On mesa 17.3, function anv_CreateImageView:

iview->n_planes = anv_image_aspect_get_planes(iview->aspect_mask);

    iview->aspect_mask is 0x6, n_planes is 1

anv_foreach_image_aspect_bit(iaspect_bit, image, expanded_aspects) {

    expanded_aspects is 0x6, the loop runs *twice*

iview->planes[vplane].optimal_sampler_surface_state.state = alloc_surface_state(device);
         iview->planes[vplane].general_sampler_surface_state.state = alloc_surface_state(device);

    Allocated surface state for vplane 0 and 1

In function anv_DestroyImageView:

for (uint32_t plane = 0; plane < iview->n_planes; plane++) {

Loop runs only once.

Thanks for the report Craig, just sent a fix for this : https://patchwork.freedesktop.org/patch/216846/
Comment 2 Craig Stout 2018-04-12 18:42:17 UTC
I'll give it a try.
Comment 3 Craig Stout 2018-04-12 18:50:15 UTC
I'm seeing this message:

INTEL-MESA: error: ../../third_party/mesa/src/intel/vulkan/genX_cmd_buffer.c:971 ASSERT: iview->n_planes == 1
Comment 4 Lionel Landwerlin 2018-04-12 20:17:35 UTC
Hm.. Either we don't have a test covering this or asserts are disabled our CI :(
Comment 5 Mark Janes 2018-04-12 21:00:09 UTC
Asserts are on in CI
Comment 6 Lionel Landwerlin 2018-04-12 21:00:58 UTC
Thanks, just noticed it's an anv_assert() which just prints out something.
Running a new patch now.
Comment 7 Lionel Landwerlin 2018-04-12 22:02:57 UTC
v2 sent.
Comment 8 Craig Stout 2018-04-13 18:33:31 UTC
v2 looks good to me.
