So about this locking piglit test (depthstencil-render-miplevels 146 s=z24_s8_d=z32f_s8), I've been able to track it down to: line 218: piglit_report_result(PIGLIT_SKIP);
How did you determine that? It's weird, I wouldn't expect a skipped test to produce any actual GPU rendering.
I used gdb and step into the code until it locked. It gets out at level 0, after going through:
/** * Attach the proper miplevel of each texture to the framebuffer */ void set_up_framebuffer_for_miplevel(int level)...
Before this call, there is a framebuffer initialization: GLuint fbo; glGenFramebuffers(1, &fbo); glBindFramebuffer(GL_DRAW_FRAMEBUFFER, fbo); glBindFramebuffer(GL_READ_FRAMEBUFFER, fbo);
for (int level = 0; level <= max_miplevel; ++level) { set_up_framebuffer_for_miplevel(level);
