[Intel-gfx] [PATCH v2 00/21] drm/i915: Organize most GPU features by platform

[Carlos Santa]

This patchset includes the following changes:

 - organize most GPU features so that they are easy to group by platforms.
   It seems some of the ground work was already done for Gen7 features.
   Reuse some of that work for the rest of the Gen platforms (GEN6, GEN5, GEN4, GEN3
   and GEN2).

 - make most of these GPU features now a device_info flag also based on
   previous work done by others. The idea is here is to have a central place where
   to add new features and also now it should be possible to see what the supported 
   features are for a given platform by dumping of the struct definitions.
   The list of the features that were converted to a device_info flag include: PSR,
   RUNTIME_PM, CORE_RING_FREQ, CSR, GUC, RESOURCE_STREAMER, RC6,
   RC6p, DP_MST, GMBUS_IRQ, FW_BLC, HW_CONTEXTS, LOGICAL_RING_CONTEXTS, L3_DPF, and
   GMCH_DISPLAY.

- Changes since v1, thanks to Rodrigo and others for the comments

- Patch 1: "drm/i915: Make GEN7_FEATURES inherit from GEN6"
  - Avoid further code duplication by making GEN7 inherit from GEN6
  - Disabled RPM for IVB and added a FIXME comment

- Patch 2: "drm/i915: Move HAS_CSR definition to platform definition"
  - Spreads out the features instead of creating a new define for GEN9_FEATURES

- Patch 3: "drm/i915: Move HAS_GUC_UCODE definition to platform definition"
  - Kill off this patch, not needed

- Patch 4: "drm/i915: Move HAS_GUC_SCHED definition to platform definition"
  - Kill off this patch, not needed

- Patch 5: "drm/i915: Move HAS_RC6p definition to platform definition"
  - Eliminate the need of creating yet another macro for IVB_FEATURES, simply list
    the features by platform

- Patch 6: "drm/i915: Move HAS_DP_MST definition to platform definition"
  - Now it correctly list the platforms that support this feature

- Patch 7: "drm/i915: Make GEN6_FEATURES inherit from GEN5"
  - Avoid further code dup by making GEN6 inherit from GEN5

- Patch 8: "drm/i915: Introduce GEN4_FEATURES for device info"
  - Introduce GEN4 features, but kill off creating new sub categories for
    GEN4 platforms.

- Patch 9: "drm/i915: Introduce GEN3_FEATURES for device info"
  - Introduce GEN3 features, but kill off creating new sub categories for
    GEN4 platforms.

- Patch 10: "drm/i915: Introduce GEN2_FEATURES for device info"
  - Introduce GEN2 features, fix a minor bug with num_pipes

- Patch 10: "drm/i915: Move HAS_L3_DPF definition to platform definition"
  - Fix which platforms actually support this feature
