From 58d11524dace34f6e9e513b23eaeb098d1eafd0b Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Sun, 10 Jun 2012 19:11:55 -0700 Subject: [PATCH] mesa: Add GL_TEXTURE_CUBE_MAP to _mesa_max_texture_levels(). [v2] For cube maps, _mesa_generate_mipmap() calls this with GL_TEXTURE_CUBE_MAP (the gl_texture_object's Target) rather than one of the faces. This caused _mesa_max_texture_levels() to return 0, which resulted in maxLevels == -1 and the next line's assertion to fail. This function is called from seven places: - fbobject.c: framebuffer_texture() - mipmap.c: _mesa_generate_mipmap() - texgetimage.c: - getteximage_error_check() - getcompressedteximage_error_check() - texparam.c: _mesa_GetTexLevelParameteriv() - texstorage.c: tex_storage_error_check() All of these (or their callers) now explicitly check for invalid targets already, so this shouldn't cause invalid targets to slip through. (Technically _mesa_generate_mipmap() doesn't check for invalid targets, but the API-facing _mesa_GenerateMipmapEXT() function does.) +2 oglconforms (float-texture/mipmap.automatic and mipmap.manual) In addition to fixing the mipmap bug, it should also cause glTexStorage to accept GL_TEXTURE_CUBE_MAP, which is explicitly allowed by the spec. v2: Drop alterations to callers; this is now in a patch series that adds explicit checking to API functions.
