[PATCH 0/2 V4] Power-well API implementation for Haswell

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

   This is V4 and here're some changes notes:

   change between V3-->V4:
   - add new structure i915_power_well
   - initialize drm_device pointer at module init time
   - change function name

   change between V2-->V3:
   - make SND_HDA_I915 selectable
   - use snd_printdd to output message
   - add return error code check
   - use symbol_request to replace symbol_get
   - release power_well at azx_free
   - some typo fixes

   changes between V1-->V2:
   - use reference count to track power-well usage
   - remove external module, compiled into snd-hda-intel instead
   - manage symbols and module loading properly
   - remove IS_HSW macro, use flag instead
   - remove audio callback for gfx driver to avoid dependency 
   - split whole patch into two pieces for easy review
   - more typo fixes
