Description Clayton Craft 2018-05-21 22:02:09 UTC 
devinfo->l3_banks is not initialized for GLK gpus with PCI device ID 3185. This causes deqp, cts, and piglit tests to fail:

shader_runner: ../src/intel/common/gen_l3_config.c:314: get_l3_way_size: Assertion `devinfo->l3_banks' failed.

    i965/glk: Add l3 banks count for 2x6 configuration
    
    2x6 configuration with pci-id 0x3185 has same number of
    banks (2) as 3x6 configuration (pci-id 0x3184).
