On gmch platforms the normal pipe source CRC registers don't work for DP and TV encoders. And on newer platforms the single pipe CRC has been replaced by a set of CRC at different stages in the platform. Now most of our userspace tests don't care one bit about the exact CRC, they simply want something that reflects any changes on the screen. Hence add a new auto target for platform agnostic tests to use. v2: Pass back the adjusted source so that it can be shown in debugfs. v3: I seem to be unable to get a stable CRC for DP ports. So let's just disable them for now when using the auto mode. Note that testcases need to be restructured so that they can dynamically skip connectors. They also first need to set up the desired mode configuration, since otherwise the auto mode won't do the right thing. v4: Don't leak the modeset mutex on error paths. v5: Spelling fix for the i9xx auto_source function.

Now we only print messages when we actually enable VDD and when we actually disable VDD. The changes in the last commit triggered a big number of messages while the driver was being initialized, and I thought we were toggling things on/off too many times, but that was not really true: we were just being too verbose.

If the eDP output is disabled, then we try to use /dev/i2c-X file to do i2c transations, we get a WARN from intel_dp_check_edp() saying we're trying to do AUX communication with the panel off. So this commit reorganizes the code so we enable the VDD at intel_dp_i2c_aux_ch() instead of just the callers inside i915.ko. This fixes the i2c subtest from the pc8 test of intel-gpu-tools on machines that have eDP panels. Signed-off-by:

Similarly rename the other related functions in the power domain interface. Higher level driver code calling these functions knows only about power domains, not the underlying power wells which may be different on different platforms. Also these functions really init/cleanup/resume power domains and only through that all related power wells, so rename them accordingly. Note that I left i915_{request,release}_power_well as is, since that really changes the state only of a single power well (and is HSW specific). It should also get a better name once we make it more generic by controlling things through a new audio power domain. v4: - use intel prefix instead of i915 everywhere (Paulo) - use a $prefix_$block_$action format (Daniel) Signed-off-by:

We store cursor_x/y as int16_t internally, but the user provided coordinates are int32_t. Clamp the coordinates so that they don't overflow the int16_t. Since the cursor is only 64x64 in size, the clamping can't cause any visual changes. Signed-off-by:

The only real need for this field was in i915_{request,release}_power_well, but there we can get at it by a container_of magic. Also since in the future we'll have multiple power wells each with its own power_well struct it makes sense to remove the field from there where it'd be just redundancy. Suggested-by: -

Currently we make sure that all power domains are enabled during driver init and turn off unneded ones only after the first modeset. Similarly during suspend we enable all power domains, which will remain on through the following resume until the first modeset. This logic is supported by intel_set_power_well() in the power domain framework. It would be nice to simplify the API, so that we only have get/put functions and make it more explicit on the higher level how this "power well on during init" logic works. This will make it also easier if in the future we want to shorten the time the power wells are on. For this add a new device private flag tracking whether we have the power wells on because of init/suspend and use only intel_display_power_get()/put(). As nothing else uses intel_set_power_well() we can remove it. This also fixes commit 6efdf354 Author: Imre Deak <imre.deak@intel.com> Date: Wed Oct 16 17:25:52 2013 +0300 drm/i915: enable only the needed power domains during modeset where removing intel_set_power_well() resulted in not releasing the reference on the power well that was taken during init and thus leaving the power well on all the time. Regression reported by Paulo. v2: - move the init_power_on flag to the power_domains struct (Daniel) v3: - add note about this being a regression fix too (Paulo) Signed-off-by:

In the future we'll need to support multiple power wells, so prepare for that here. Create a new power domains struct which contains all power domain/well specific fields. Since we'll have one lock protecting all power wells, move power_well->lock to the new struct too. No functional change. Signed-off-by:

All our registers which are written through the MCHBAR are defined descriptively as an offset to the MCHBAR. We had 3 outliers here. Convert these as well so all registers which are offsets are MCHBAR can be easily identified/found within the code. With this, convert DCLK to also follow this format. Signed-off-by:

Daniel pointed out that it was hard to get anything lockless to work correctly, so don't even try for this non critical piece of code and just use a spin lock. v2: Make intel_pipe_crc->opened a bool v3: Use assert_spin_locked() instead of a comment (Daniel Vetter) v4: Use spin_lock_irq() in the debugfs functions (they can only be called from process context), Use spin_lock() in the pipe_crc_update() function that can only be called from an interrupt handler, Use wait_event_interruptible_lock_irq() when waiting for data in the cicular buffer to ensure proper locking around the condition we are waiting for.

So far the modeset code enabled all power domains if it needed any. It wasn't a problem since HW generations so far only had one always-on power well and one dynamic power well that can be enabled/disabled. For domains powered by always-on power wells (panel fitter on pipe A and the eDP transcoder) we didn't do anything, for all other domains we just enabled the single dynamic power well. Future HW generations will change this, as they add multiple dynamic power wells. Support for these will be added later, this patch prepares for those by making sure we only enable the required domains. Note that after this change on HSW we'll enable all power domains even if it was the domain for the panel fitter on pipe A or the eDP transcoder. This isn't a problem since the power domain framework already checks if the domain is on an always-on power well and doesn't do anything in this case. Signed-off-by:

There is no hard need for this to be a spin lock, as we don't take these locks in irq context from anywhere. An upcoming patch will add calls to punit read/write functions from within regions protected by this lock and those functions need a mutex in turn. As a solution for that convert the spin lock to be a mutex. Signed-off-by:

Since we use intel_enable_rc6() now for more than just when we're enabling RC6, we'll see this message many times, and it is just confusing. As an example, calc_residency calls this function whenever poked via sysfs. This leaves the impression in dmesg that we're constantly re-enabling RC6. While at it, move the defines and description from drv.h to intel_pm.c, since these are only ever used in that code. Signed-off-by:
