      drm/i915: Add support for DP Video pattern compliance tests · 611032bf
      由 Manasi Navare 提交于 
      The intel_dp_autotest_video_pattern() function gets invoked through the
compliance test handler on a HPD short pulse if the test type is
set to DP_TEST_VIDEO_PATTERN. This performs the DPCD registers
reads to read the requested test pattern, video pattern resolution,
frame rate and bits per color value. The results of this analysis
are handed off to userspace so that the userspace app can set the
video pattern mode appropriately for the test result/response.
When the  test is requested with specific BPC value, we read the BPC
value from the DPCD register. If this BPC value in intel_dp structure
has a non-zero value and we're on a display port connector, then we use
the value to calculate the bpp for the pipe. Also in this case if its
a 18bpp video pattern request, then we force the dithering on pipe to be
disabled since it causes CRC mismatches.

The compliance_test_active flag is set at the end of the individual
test handling functions. This is so that the kernel-side operations
can be completed without the risk of interruption from the userspace
app that is polling on that flag.

v5:
* Remove test_result variable
* Populate the compliance test data at the end of the function (Jani Nikula)
v4:
*Return TEST_NAK on read failures and invalid values (Jani Nikula)
* Address CRC mismatch errors
v3:
* Use the updated properly shifted bit definitions (Jani Nikula)
* Force dithering to be disabled on 18bpp compliance
test request (Manasi Navare)
v2:
* Updated the DPCD Register reads based on proper defines in header (Jani Nikula)
* Squahsed the patch that forced the pipe bpp to compliance test bpp (Jani Nikula)

      drm/i915: Fixes to support DP Compliance EDID tests · b48a5ba9
      由 Manasi Navare 提交于 
      This patch addresses a few issues from the original patch for
DP Compliance EDID test support submitted by
Todd Previte<todd.previte@gmail.com>

Video Mode requested in the EDID test handler for the EDID Read
test (CTS 4.2.2.3) should be set to PREFERRED as per the CTS spec.

v2:
* Added read debugfs data from test_data.edid if its EDID test (Jani NIkula)

      drm: Nuke fb->pixel_format · 438b74a5
      由 Ville Syrjälä 提交于 
      Replace uses of fb->pixel_format with fb->format->format.
Less duplicated information is a good thing.

Note that coccinelle failed to eliminate the
"/* fourcc format */" comment from drm_framebuffer.h, so I had
to do that part manually.

      drm: Nuke fb->bits_per_pixel · 272725c7
      由 Ville Syrjälä 提交于 
      Replace uses of fb->bits_per_pixel with fb->format->cpp[0]*8.
Less duplicated information is a good thing.

Note that I didn't put parens around the cpp*8 in the below cocci script,
on account of not wanting spurious parens all over the place. Instead I
did the unsafe way, and tried to look over the entire diff to spot if
any dangerous expressions were produced. I didn't see any.

There are some cases where previously the code did X*bpp/8, so the
division happened after the multiplication. Those are now just X*cpp
so the division effectively happens before the multiplication,
but that is perfectly fine since bpp is always a multiple of 8.
