Bug ID: 108261 Summary: [amdgpu][GL_ARB_bindless_texture][opengl 4] GPU hang on AMD Raven Product: Mesa Version: git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: RobusGrobus95@gmail.com QA Contact: dri-devel@lists.freedesktop.org

GPU hang appears when trying to render scene to FBO (framebuffer object) with attached texture with resident handle, but if all the handles of attached texture are not reesident (or if there is no handles), hang disappears. For example this pseudocode causes GPU hang: GLuint renderbufId; glCreateRenderbuffers(1, &renderbufId); glNamedRenderbufferStorage(renderbufId, GL_DEPTH_COMPONENT, width(), height());

GLuint texId; glCreateTextures(GL_TEXTURE_2D, 1, &texId); glTextureStorage2D(texId, 1, GL_RGBA8, width(), height());

GLuint64 handle = glGetTextureHandleARB(texId); glMakeTextureHandleResidentARB(handle);

glBindFramebuffer(GL_FRAMEBUFFER, fboID); glFramebufferTexture(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, texId, 0); glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_RENDERBUFFER, rboId); //render some triangles glBindFramebuffer(GL_FRAMEBUFFER, 0); //render main scene glSwapBuffers();

And this not: GLuint renderbufId; glCreateRenderbuffers(1, &renderbufId); glNamedRenderbufferStorage(renderbufId, GL_DEPTH_COMPONENT, width(), height());

GLuint texId; glCreateTextures(GL_TEXTURE_2D, 1, &texId); glTextureStorage2D(texId, 1, GL_RGBA8, width(), height());

GLuint64 handle = glGetTextureHandleARB(texId); std::cout << handle << std::endl; //prevent optimizing out

glBindFramebuffer(GL_FRAMEBUFFER, fboID); glFramebufferTexture(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, texId, 0); glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_RENDERBUFFER, rboId); //render some triangles glBindFramebuffer(GL_FRAMEBUFFER, 0); //render main scene glSwapBuffers();

I can try to write full cpp sample for exposing the hang, if it's needed. There is already open source graphic engine (my "pet" project) affected by the hang, but code is quite complex (https://gitlab.com/KawaiiGraphics/Kawaii3D https://gitlab.com/KawaiiGraphics/Misaka3D ; workaround added in commit b53d98dacff2b0392c2143c8901289e93ddd8623, so only previous versions are affected).
