From de783a6897e0f67f456793b10c48f24e5ee70a85 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Tue, 26 Mar 2019 00:25:31 -0700 Subject: [PATCH] iris: Actually advertise some modifiers I neglected to fill out this driver function, causing us to advertise 0 modifiers. Now we advertise the various tilings and let the driver pick them. I've verified that X tiling works with Weston (by hacking the list to skip Y tiling). Y+CCS doesn't work yet because it's multiplane and the Gallium dri state tracker isn't really prepared for that. Leave it off for now. --- src/gallium/drivers/iris/iris_resource.c | 39 ++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) diff --git a/src/gallium/drivers/iris/iris_resource.c b/src/gallium/drivers/iris/iris_resource.c index 164647b..bf8af13 100644 --- a/src/gallium/drivers/iris/iris_resource.c +++ b/src/gallium/drivers/iris/iris_resource.c @@ -139,6 +139,44 @@ target_to_isl_surf_dim(enum pipe_texture_target target) unreachable("invalid texture type"); } +static void +iris_query_dmabuf_modifiers(struct pipe_screen *pscreen, + enum pipe_format pfmt, + int max, + uint64_t *modifiers, + unsigned int *external_only, + int *count) +{ + struct iris_screen *screen = (void *) pscreen; + const struct gen_device_info *devinfo = &screen->devinfo; + + uint64_t all_modifiers[] = { + DRM_FORMAT_MOD_LINEAR, + I915_FORMAT_MOD_X_TILED, + I915_FORMAT_MOD_Y_TILED, + // XXX: (broken) I915_FORMAT_MOD_Y_TILED_CCS, + }; + + int supported_mods = 0; + + for (int i = 0; i < ARRAY_SIZE(all_modifiers); i++) { + if (!modifier_is_supported(devinfo, all_modifiers[i])) + continue; + + if (supported_mods < max) { + if (modifiers) + modifiers[supported_mods] = all_modifiers[i]; + + if (external_only) + external_only[supported_mods] = util_format_is_yuv(pfmt); + } + + supported_mods++; + } + + *count = supported_mods; +} + static isl_surf_usage_flags_t pipe_bind_to_isl_usage(unsigned bindings) { @@ -1442,6 +1480,7 @@ static const struct u_transfer_vtbl transfer_vtbl = { void iris_init_screen_resource_functions(struct pipe_screen *pscreen) { + pscreen->query_dmabuf_modifiers = iris_query_dmabuf_modifiers; pscreen->resource_create_with_modifiers = iris_resource_create_with_modifiers; pscreen->resource_create = u_transfer_helper_resource_create; -- 2.7.4
