glxinfo
Every OpenGL application that wants to use a depth buffer always crashes,
including glxgears:
glxgears: dri2.c:906: dri2_allocate_textures: Assertion `*zsbuf' failed.
I debugged the assertion with gdb:
templ structure contents passed to resource_create():
$2 = {reference = {count = 0}, width0 = 300, height0 = 300, depth0 = 1,
array_size = 1, format = PIPE_FORMAT_Z24X8_UNORM,
target = PIPE_TEXTURE_2D, last_level = 0, nr_samples = 0, nr_storage_samples
= 0, usage = 0, bind = 1, flags = 0,
next = 0x0, screen = 0x0}
In nv50_miptree_create() in gallium/drivers/nouveau/nv50/nv50_miptree.c:389
the call to nouveau_bo_new() returns -22 that causes it to return NULL.
MESA_DEBUG=1 glxgears prints the following before segfaulting:
Mesa: User error: GL_OUT_OF_MEMORY in Resizing framebuffer
Computer: MacBook Pro 2010 (NVIDIA GeForce 320M "MCP89")
Resolution: 1280x800
OS: Lubuntu 18.10
Mesa: 18.2.2, but happens also with the versions that come with Lubuntu 16.04
and 18.04
I can compile and run mesa from sources, if it helps debugging.</pre>
