    drm/i915/bdw: Apply workarounds in render ring init function · 86d7f238
    Arun Siluvery authored
    For BDW workarounds are currently initialized in init_clock_gating() but
    they are lost during reset, suspend/resume etc; this patch moves the WAs
    that are part of register state context to render ring init fn otherwise
    default context ends up with incorrect values as they don't get initialized
    until init_clock_gating fn.
    
    v2: Add workarounds to golden render state
    This method has its own issues, first of all this is different for
    each gen and it is generated using a tool so adding new workaround
    and mainitaining them across gens is not a straightforward process.
    
    v3: Use LRIs to emit these workarounds (Ville)
    Instead of modifying the golden render state the same LRIs are
    emitted from within the driver.
    
    v4: Use abstract name when exporting gen specific routines (Chris)
