Currently the machine hangs during booting while accessing the BXT_MIPI_PORT_CTRL register during pipe HW state readout. After some experimentation I found that the hang is caused by the DSI PLL being disabled, or it being enabled but with an incorrect divider configuration. Enabling the PLL got rid of the boot problem, so fix this by checking the PLL enabled state/configuration before attempting to read out the HW state. The DSI_PLL_ENABLE register is in the always-on power well, while the BXT_DSI_PLL_CTL is in power well 0. This isn't exactly matched by the transcoder power domain, but what we really need is just a runtime PM reference, which is provided by any power domain. Ville also found this dependency specified in BSpec, so I added a reference to that too. v2: - Make sure we hold a power reference while accessing the PLL registers. v3: (Jani) - Simplify check in bxt_get_dsi_transcoder_state() - Add comment explaining why we check for valid dividers in bxt_dsi_pll_is_enabled() CC: Shashank Sharma <shashank.sharma@intel.com> CC: Uma Shankar <uma.shankar@intel.com> CC: Jani Nikula <jani.nikula@intel.com> Fixes: c6c794a2 ("drm/i915/bxt: Initialize MIPI DSI for BXT") Signed-off-by:

In commit 0a878716 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Oct 15 14:23:01 2015 +0200 drm/i915: restore ggtt double-bind avoidance we wrote the ggtt_bind_vma() observing a number of cleanups we could do over the template of aliasing_gtt_bind_vma(). Now let's apply the cleanups we made there back to the original. The essence is to avoid redundant variables and assignements, and by doing so make the code easier to read. Signed-off-by:

In order for VLV and CHV to use i9xx_crtc_compute_clocks(), a number of if ladders is necessary: one for setting the find_dpll() hook, one for choosing the limits struct, one for choosing the right compute dpll function and one for initializing the crtc_compute_clock() hook. By extracting a platform specific implementation for each platform, the number of if-ladders is reduced to one. While at it also clean up bxt_find_best_dpll() which depends on some of the CHV code.

When calculating clocks, just pass a pointer to crtc_state->dpll directly to the find_dpll() hook. Back when this was introduced in commit f47709a9 ("drm/i915: create pipe_config->dpll for clock state") there was no staged crtc config or atomic crtc state, so it was possible to overwrite the current configuration on error. That hasn't been the case for a while now, so finally make it "disappear". Signed-off-by:

None of the code in ironlake_crtc_compute_clock() is relevant for CPU eDP. The CPU eDP PLL is turned on and off in ironlake_edp_pll_{on,off} from the DP code and that doesn't depend on the crtc_state->dpll values, so just return early in that case. v2: Rebase without patch that drops lvds downclock code.

The checks were added in commit 5dc5298b ("drm/i915: add proper CPU/PCH checks to crtc_mode_set functions") in a time when there was doubts on what PCHs would be supported by HSW. There are similar checks for PCH type in intel_detect_pch() and the function pointers are initialized based on platform/pch information, so the removed WARN can't ever be reached. v2: Rebase without patch that drops lvds downclock code.

Remove the clock calculation from ironlake_crtc_compute_clock() when the encoder compute_config() already set one. The value was just thrown away in that case. Note that the previously set clock is not validated against the limits anymore. That is ok since the fixed clocks from DP and SDVO are within the supported range, so the call to ironlake_compute_clocks() would never fail in that case. v2: Add note about not checking fixed clocks agains limits.

The wait for other gens was added in commit 564ed191 ("drm/i915: gmch: fix stuck primary plane due to memory self-refresh mode") since that's necessary when disabling cxsr. However, cxsr disabling was later moved to intel_pre_disable_primary() in commit 87d4300a ("drm/i915: Move intel_(pre_disable/post_enable)_primary to intel_display.c, and use it there.") and that function got its own vblank wait for cxsr in commit 262cd2e1 ("drm/i915: CHV DDR DVFS support and another watermark rewrite"). So remove the extra vblank wait from i9xx_crtc_distable(). Cc: Kalyan Kondapally <kalyan.kondapally@intel.com> Signed-off-by:

Commit d15d7538 ("drm/i915: Tune down init error message due to failure injection") added i915_load_error message to failure path on device initialization. The message is printed after the device is freed. And as the message printing helper uses the device structure, this leads to use after free. Spotted by Kasan.

Joonas and Daniel remarked that our debugging output should stay compatible with the core DRM's debug facility. The recently added __i915_printk() would output debug messages even if debugging is completely disabled via the drm.debug option. To fix this make __i915_printk behave the same as DRM_DEBUG_DRIVER in this case.

At the end of an atomic commit, we currently wait for vblanks to complete, call put() on the various runtime PM references, and then try to optimize our watermarks (on platforms that need two-step watermark programming). This can lead to watermark registers being programmed while the power well is powered down. We need to wait until after watermark optimization is complete before dropping our runtime power references. Note that in the future the watermark optimization is probably going to move to an asynchronous workqueue task that happens at some arbitrary point after vblank. When we make that change, we'll no longer necessarily be operating under the power reference held here, so we'll need to wrap the watermark register programmin in a call to intel_runtime_pm_get_if_in_use() or similar.

The moves a couple of functions programming the gamma LUT and CSC units into their own file. On generations prior to Haswell there is only a gamma LUT. From haswell on there is also a new enhanced color correction unit that isn't used yet. This is why we need to set the GAMMA_MODE register, either we're using the legacy 8bits LUT or enhanced LUTs (of 10 or 12bits). The CSC unit is only available from Haswell on. We also need to make a special case for CherryView which is recognized as a gen 8 but doesn't have the same enhanced color correction unit from Haswell on. v2: Fix access to GAMMA_MODE register on older generations than Haswell (from Matt Roper's comments) Signed-off-by: -

The BXT display connections have DSI transcoders A and C that can be muxed to any pipe, not unlike the eDP transcoder. Add the notion of DSI transcoders. The "normal" transcoders A, B and C are not used with BXT DSI, so care must be taken to avoid accessing those registers with DSI transcoders in the hardware state readout, modeset, and generally everywhere. v2: addressing comments by Ville: - rename the dsi get config function to hsw_get_dsi_transcoder_state - rebase onto the higher level split of pipe/transcoder functions - use more has_dsi_encoder as we can now because of the above, with no need to look at the transcoder so much - rename IS_DSI_TRANSCODER to transcoder_is_dsi - use the above a bit more instead of comparing to < TRANSCODER_EDP Reviewed-by:
