      drm/i915/params: switch to device specific parameters · 8a25c4be
      Jani Nikula 提交于
      Start using device specific parameters instead of module parameters for
      most things. The module parameters become the immutable initial values
      for i915 parameters. The device specific parameters in i915->params
      start life as a copy of i915_modparams. Any later changes are only
      reflected in the debugfs.
      
      The stragglers are:
      
      * i915.force_probe and i915.modeset. Needed before dev_priv is
        available. This is fine because the parameters are read-only and never
        modified.
      
      * i915.verbose_state_checks. Passing dev_priv to I915_STATE_WARN and
        I915_STATE_WARN_ON would result in massive and ugly churn. This is
        handled by not exposing the parameter via debugfs, and leaving the
        parameter writable in sysfs. This may be fixed up in follow-up work.
      
      * i915.inject_probe_failure. Only makes sense in terms of the module,
        not the device. This is handled by not exposing the parameter via
        debugfs.

      drm/i915/guc: kill doorbell code and selftests · e9362e13
      Daniele Ceraolo Spurio 提交于
      Instead of relying on the workqueue, the upcoming reworked GuC
      submission flow will offer the host driver indipendent control over
      the execution status of each context submitted to GuC. As part of this,
      the doorbell usage model has been reworked, with each doorbell being
      paired to a single lrc and a doorbell ring representing new work
      available for that specific context. This mechanism, however, limits
      the number of contexts that can be registered with GuC to the number of
      doorbells, which is an undesired limitation. To avoid this limitation,
      we requested the GuC team to also provide a H2G that will allow the host
      to notify the GuC of work available for a specified lrc, so we can use
      that mechanism instead of relying on the doorbells. We can therefore drop
      the doorbell code we currently have, also given the fact that in the
      unlikely case we'd want to switch back to using doorbells we'd have to
      heavily rework it.
      The workqueue will still have a use in the new interface to pass special
      commands, so that code has been retained for now.
      
      With the doorbells gone and the GuC client becoming even simpler, the
      existing GuC selftests don't give us any meaningful coverage so we can
      remove them as well. Some selftests might come with the new code, but
      they will look different from what we have now so if doesn't seem worth
      it to keep the file around in the meantime.
