2014-10-16drm/i915: Don't trust the DP_DETECT bit for eDP ports on CHVVille Syrjälä1-12/+21
On CHV the display DDC pins may be muxed to an alternate function if there's no need for DDC on a specific port, which is the case for eDP ports since there's no way to plug in a DP++ HDMI dongle. This causes problems when trying to determine if the port is present since the the DP_DETECTED bit is the latched state of the DDC SDA pin at boot. If the DDC pins are muxed to an alternate function the bit may indicate that the port isn't present. To work around this look at the VBT as well as the DP_DETECTED bit to determine if we should attempt registering an eDP port. Do this only for ports B and C since port D doesn't support eDP (no PPS/BLC). In theory someone could also wire up a normal DP port w/o DDC lines. That would just mean that simple DP++ HDMI dongles wouldn't work on such a port. With this change we would still fail to register such DP ports. But let's hope no one wires their board in such a way, and if they do we can extend the VBT checks to cover normal DP ports as well.

Improper truncated integer division in the scale() function causes actual_brightness != brightness. This (partial) work-around should be sufficient for a majority of use-cases, but it is by no means a complete solution.

2014-09-30ACPI / i915: Update the condition to ignore firmware backlight change requestAaron Lu1-5/+11
Some of the Thinkpads' firmware will issue a backlight change request through i915 operation region unconditionally on AC plug/unplug, the backlight level used is arbitrary and thus should be ignored. This is handled by commit 0b9f7d93ca61 (ACPI / i915: ignore firmware requests for backlight change). Then there is a Dell laptop whose vendor backlight interface also makes use of operation region to change backlight level and with the above commit, that interface no long works. The condition used to ignore the backlight change request from firmware is thus changed to: if the vendor backlight interface is not in use and the ACPI backlight interface is broken, we ignore the requests; oterwise, we keep processing them.

If we fail to create our mmu notification, we report the error back and currently store the error inside the i915_mm_struct. This not only causes subsequent registerations of the same mm to fail (an issue if the first was interrupted by a signal and needed to be restarted) but also causes us to eventually try and free the error pointer.

2014-09-19drm/i915: HSW always use GGTT selector for secure batchesChris Wilson1-2/+3
gen6 and earlier conflate address space selection (ppgtt vs ggtt) with the security bit (i.e. only privileged batches were allowed to run from ggtt). From Haswell only, you are able to select the security bit separate from the address space - and we always requested to use ppgtt. This breaks the golden render state batch execution with full-ppgtt as that is only present in the global GTT and more generally any secure batch that is not colocated in the ppgtt and ggtt. So we need to disable the use of the ppgtt selector bit for secure batches, or else we hang immediately upon boot and thence after every GPU reset... v2: Only HSW differentiates between secure dispatch and ggtt, so simply ignore the differentiation and always use secure==ggtt.

Limit the watermark value to at least 8 cache lines. That also matches the burst size we use on most platforms. BSpec seems to indicate we should limit the watermark to 'burst size + 1'.

Apparently the pipe has to go through one full frame before we enable the TV port. Add a vblank wait to intel_enable_tv() to make sure that happens. Another approach was attempted by placing the vblank wait just after enabling the port. The theory behind that attempt was that we need to let the port stay enabled for one full frame before disabling it again during load detection. But that didn't work, and we definitely must have the vblank wait before enabling the port.
