      drm/i915: move module parameters into a struct, in a new file · d330a953
      由 Jani Nikula 提交于 
      With 20+ module parameters, I think referring to them via a struct
improves clarity over just having a bunch of globals. While at it, move
the parameter initialization and definitions into a new file
i915_params.c to reduce clutter in i915_drv.c.

Apart from the ill-named i915_enable_rc6, i915_enable_fbc and
i915_enable_ppgtt parameters, for which we lose the "i915_" prefix
internally, the module parameters now look the same both on the kernel
command line and in code. For example, "i915.modeset".

The downsides of the change are losing static on a couple of variables
and not having the initialization and module_param_named() right next to
each other. On the other hand, all module parameters are now defined in
one place at i915_params.c. Plus you can do this to find all module
parameter references:

$ git grep "i915\." -- drivers/gpu/drm/i915

v2:
- move the definitions into a new file
- s/i915_params/i915/
- make i915_try_reset i915.reset, for consistency

      drm/sysfs: sort out minor and connector device object lifetimes. · 5bdebb18
      由 Dave Airlie 提交于 
      So drm was abusing device lifetimes, by having embedded device structures
in the minor and connector it meant that the lifetime of the internal drm
objects (drm_minor and drm_connector) were tied to the lifetime of the device
files in sysfs, so if something kept those files opened the current code
would kfree the objects and things would go downhill from there.

Now in reality there is no need for these lifetimes to be so intertwined,
especailly with hotplugging of devices where we wish to remove the sysfs
and userspace facing pieces before we can unwind the internal objects due
to open userspace files or mmaps, so split the objects out so the struct
device is no longer embedded and do what fbdev does and just allocate
and remove the sysfs inodes separately.

      drm/i915: re-layout intel_panel.c to obey 80 char limit · 9084e7d2
      由 Daniel Vetter 提交于 
      Especially intel_gmch_panel_fitting was shifting way too much over the
right edge and also was way too long. So extract two helpers, one for
gen4+ and one for gen2/3. Now the entire thing is again almost
readable ...

Spurred by checkpatch freaking out about a Ville's pipeconfig rework
in intel_panel.c

Otherwise just two lines that needed appropriate breaking.

Not functional change in this patch.

      drm/i915: Add explicit pipe src size to pipe config · 37327abd
      由 Ville Syrjälä 提交于 
      Rather that mess about with hdisplay/vdisplay from requested_mode, add
explicit pipe src size information to pipe config.

Now requested_mode is only really relevant for dvo/sdvo output timings.
For everything else either adjusted_mode or pipe src size should be
used.

In many places where we end up using pipe source size, we should
actually use the primary plane size, but we don't currently store
that information explicitly. As long as we treat primaries as full
screen only, we can get away with this. Eventually when we move
primaries over to drm_plane, we need to fix it all up.

v2: Add a comment to explain what pipe_src_{w,h} are
    Add a note about primary planes to commit message

      drm/i915: Fix pipe config warnings when dealing with LVDS fixed mode · 4c6df4b4
      由 Ville Syrjälä 提交于 
      intel_fixed_panel_mode() overwrote the adjusted_mode with the fixed mode
only partially. Notably it forgot to copy over the sync flags. The LVDS code however programmed the hardware with the sync flags from fixed mode, and then later the pipe config comparison obviously failed as we
filled out the adjusted_mode in get_config from the real registers.

Just call drm_mode_copy() in intel_fixed_panel_mode() to copy over the
whole thing, and then just use adjusted_mode in the LVDS code to figure
out which sync settings the hardware needs.

Also constify the fixed_mode argument to intel_fixed_panel_mode().

      drm/i915: fix lvds/dp panel fitter setting · a52690e4
      由 Imre Deak 提交于 
      If need to enable the panel fitter, the crtc timings have to be
programmed according to the panel's native (fixed) mode. This isn't the
case atm, since after the encoder changes adjusted_mode to fixed
mode the crtc_* timing fields of adjusted_mode will stay at their original
non-native values that the user passed in. This results in a corrupted
output.

One exception is when we have a second pass of computing encoder configs
due to bandwidth limitation, since then we'll set adjusted_mode.crtc_*
fields to the fixed mode values set in the first pass; so in this case
things will work out.

Fix this by updating the adjusted_mode.crtc_* fields when we set the
fixed panel mode.

This regression has been introduced in

      drm/i915: clean up crtc timings computation · 135c81b8
      由 Daniel Vetter 提交于 
      In the old days of the crtc helpers we've only had the encoder and
crtc ->mode_fixup callbacks. So when the lvds connector wanted to
adjust the crtc timings it had to set a driver-private mode flag to
tell the crtc mode fixup code to not overwrite them with the generic
ones.

When converting things to the new infrastructure I've kept the entire
logic and only moved the flag to pipe_config->timings_set. But this
logic is pretty tricky and already caused regressions:

    drm/i915: fix pfit regression for non-autoscaled resolutions

So take advantage of the flexibility our own modeset infrastructure
affords us and prefill default crtc timings. This allows us to rip out
->timings_set. Note that we overwrite things again when retrying the
pipe config computation due to bandwidth constraints to avoid bogus
crtc timings if the encoder only does relative adjustments (which is
how the pfit code works). Only a theoretical concern though since
platforms where we retry (pch-split platforms) do not need
adjustements (since only the old gmch pfit needs that). But let's
better be safe than sorry.

Since we now initialize the crtc timings before calling the
encoder->compute_config functions the crtc initialization in the gmch
pfit code is now redudant and so can be removed.

    drm/i915: factor out GMCH panel fitting code and use for eDP v3

broke that by reordering the computation of the gmch pfit state with
the block of code that prepared the adjusted mode for it and told the
modeset core not to overwrite the adjusted mode with default settings.

We might want to switch around the core code to just fill in defaults,
but this code predates the pipe_config modeset rework. And in the old
crtc helpers we did not have a suitable spot to do this.
