      drm/i915/display: rename display version macros · 93e7e61e
      由 Lucas De Marchi 提交于 
      While converting the rest of the driver to use GRAPHICS_VER() and
MEDIA_VER(), following what was done for display, some discussions went
back on what we did for display:

	1) Why is the == comparison special that deserves a separate
	macro instead of just getting the version and comparing directly
	like is done for >, >=, <=?

	2) IS_DISPLAY_RANGE() is weird in that it omits the "_VER" for
	brevity. If we remove the current users of IS_DISPLAY_VER(), we
	could actually repurpose it for a range check

With (1) there could be an advantage if we used gen_mask since multiple
conditionals be combined by the compiler in a single and instruction and
check the result. However a) INTEL_GEN() doesn't use the mask since it
would make the code bigger everywhere else and b) in the cases it made
sense, it also made sense to convert to the _RANGE() variant.

So here we repurpose IS_DISPLAY_VER() to work with a [ from, to ] range
like was the IS_DISPLAY_RANGE() and convert the current IS_DISPLAY_VER()
users to use == and != operators. Aside from the definition changes,
this was done by the following semantic patch:

	@@ expression dev_priv, E1; @@
	- !IS_DISPLAY_VER(dev_priv, E1)
	+ DISPLAY_VER(dev_priv) != E1

	@@ expression dev_priv, E1; @@
	- IS_DISPLAY_VER(dev_priv, E1)
	+ DISPLAY_VER(dev_priv) == E1

	@@ expression dev_priv, from, until; @@
	- IS_DISPLAY_RANGE(dev_priv, from, until)
	+ IS_DISPLAY_VER(dev_priv, from, until)

      drm/i915/display: Simplify GLK display version tests · 2b5a4562
      由 Matt Roper 提交于 
      GLK has always been a bit of a special case since it reports INTEL_GEN()
as 9, but has version 10 display IP.  Now we can properly represent the
display version as 10 and simplify the display generation tests
throughout the display code.

Aside from manually adding the version to the glk_info structure, the
rest of this patch is generated with a Coccinelle semantic patch.  Note
that we also need to switch any code that matches gen10 today but *not*
GLK to be CNL-specific:

v2:
 - Convert gen10 conditions that don't include GLK into CNL conditions.

v3.1:
 - Manually re-add the ".display.version = 10" to glk_info after
   regenerating patch via Coccinelle.

v4:
 - Also apply cocci rules to intel_pm.c and i915_irq.c!  (CI)

      drm/i915/display: Support PSR Multiple Instances · b64d6c51
      由 Gwan-gyeong Mun 提交于 
      It is a preliminary work for supporting multiple EDP PSR and
DP PanelReplay. And it refactors singleton PSR to Multi Transcoder
supportable PSR.
And this moves and renames the i915_psr structure of drm_i915_private's to
intel_dp's intel_psr structure.
It also causes changes in PSR interrupt handling routine for supporting
multiple transcoders. But it does not change the scenario and timing of
enabling and disabling PSR. And it not support multiple pipes with
a single transcoder PSR case yet.

v2: Fix indentation and add comments
v3: Remove Blank line
v4: Rebased
v5: Rebased and Addressed Anshuman's review comment.
    - Move calling of intel_psr_init() to intel_dp_init_connector()
v6: Address Anshuman's review comments
   - Remove wrong comments and add comments for a limit of supporting of
     a single pipe PSR
v7: Update intel_psr_compute_config() for supporting multiple transcoder
    PSR on BDW+
v8: Address Anshuman's review comments
   - Replace DRM_DEBUG_KMS with drm_dbg_kms() / DRM_WARN with drm_warn()
v9: Fix commit message
v10: Rebased
v11: Address Jose's review comment.
  - Reorder calling order of intel_psr2_program_trans_man_trk_ctl().
  - In order to reduce changes keep the old name for drm_i915_private.
  - Change restrictions of multiple instances of PSR.
v12: Address Jose's review comment.
  - Change the calling of intel_psr2_program_trans_man_trk_ctl() into
    commit_pipe_config().
  - Change a checking order of CAN_PSR() and connector_status to original
    on i915_psr_sink_status_show().
  - Drop unneeded intel_dp_update_pipe() function.
  - In order to wait a specific encoder which belong to crtc_state on
    intel_psr_wait_for_idle(), add checking of encoder.
  - Add an whitespace to comments.
v13: Rebased and Address Jose's review comment.
  - Add and use for_each_intel_psr_enabled_encoder() macro.
  - In order to use correct frontbuffer_bit for each pipe,
    fix intel_psr_invalidate() and intel_psr_flush().
  - Remove redundant or unneeded codes.
  - Update comments.
v14: Address Jose's review comment
  - Add and use for_each_intel_encoder_can_psr() macro and
    for_each_intel_encoder_mask_can_psr() macro.
  - Add source_support member variable into intel_psr structure.
  - Update CAN_PSR() macro that checks source_support.
  - Move encoder's PSR availity check to psr_init() from
    psr_compute_config().
