2013-10-11Revert "i915: Update VGA arbiter support for newer devices"Dave Airlie
This reverts commit 81b5c7bc8de3e6f63419139c2fc91bf81dea8a7d. Adding drm/i915 into the vga arbiter chain means that X (in a piece of well-meant paranoia) will do a get/put on the vga decoding around _every_ accel call down into the ddx. Which results in some nice performance disasters [1]. This really breaks userspace, by disabling DRI for everyone, and stops OpenGL from working, this isn't limited to just the i915 but both the integrated and discrete GPUs on multi-gpu systems, in other words this causes untold worlds of pain, Ville tried to come up with a Great Hack to fiddle the required VGA I/O ops behind everyone's back using stop_machine, but that didn't really work out [2]. Given that we're fairly late in the -rc stage for such games let's just revert this all. One thing we might want to keep is to delay the disabling of the vga decoding until the fbdev emulation and the fbcon screen is set up. If we kill vga mem decoding beforehand fbcon can end up with a white square in the top-left corner it tried to save from the vga memory for a seamless transition. And we have bug reports on older platforms which seem to match these symptoms. But again that's something to play around with in -next.

2013-10-03drm/i915: Mask LPSP to get PSR working even with Power Well in use by audio.Rodrigo Vivi
Power Well in use forces constantly PSR to exit. On recent Kernel I noticed that PSR Performance Counter was always 0 indicating that PSR was never really achieved. By masking LPSP, PSR can work normally and save power on Haswell. Two bugs had been raised with PSR flag enabled: - "Screen flickers when booted by enabling PSR in the kernel (i915.enable_psr=1) , the system is booting to a gray screen." - "When booting the DUT with PSR feature enabled in the kernel (i915.enable_psr=1) , the system is booting to a gray screen."

2013-10-01drm/i915: fix rps.vlv_work initializationImre Deak
During driver loading we are initializing rps.vlv_work in valleyview_enable_rps() via the rps.delayed_resume_work delayed work. This is too late since we are using vlv_work already via i915_driver_load()->intel_uncore_sanitize()-> intel_disable_gt_powersave(). This at least leads to the following kernel warning: INFO: trying to register non-static key. the code is fine but needs lockdep annotation. turning off the locking correctness validator. Fix this by initialzing vlv_work before we call intel_uncore_sanitize().

Note that after resume the bios might or might not have enabled pipe A already.

2013-09-24drm/i915/tv: clear adjusted_mode.flagsDaniel Vetter
The native TV encoder has it's own flags to adjust sync modes and enabled interlaced modes which are totally irrelevant for the adjusted mode. This worked out nicely since the input modes used by both the load detect code and reported in the ->get_modes callbacks all have no flags set, and we also don't fill out any of them in the ->get_config callback. This changed with the additional sanitation done with commit 2960bc9cceecb5d556ce1c07656a6609e2f7e8b0 Author: Imre Deak <imre.deak@intel.com> Date: Tue Jul 30 13:36:32 2013 +0300 drm/i915: make user mode sync polarity setting explicit sinc now the "no flags at all" state wouldn't fit through core code any more. So fix this up again by explicitly clearing the flags in the ->compute_config callback. Aside: We have zero checking in place to make sure that the requested mode is indeed the right input mode we want for the selected TV mode. So we'll happily fall over if userspace tries to pull us. But that's definitely work for a different patch series. So just add a FIXME comment for now.

2013-09-24drm/i915/dp: increase i2c-over-aux retry interval on AUX DEFERJani Nikula
There is no clear cut rules or specs for the retry interval, as there are many factors that affect overall response time. Increase the interval, and even more so on branch devices which may have limited i2c bit rates.

2013-09-24drm/i2c: tda998x: fix audio mutingRussell King
Fix a bug that was introduced in commit c4c11dd160a8 ("drm/i2c: tda998x: add video and audio input configuration") when Sebastian cleaned up my original patch. Without this being fixed, audio is muted when the display is turned off, never to be re-enabled.

2013-09-24drm/i915: Use a temporary va_list for two-pass string handlingChris Wilson
In commit edc3d8848dc9fe2a470316363dab8ef211d77e01 Author: Mika Kuoppala <mika.kuoppala@linux.intel.com> Date: Thu May 23 13:55:35 2013 +0300 drm/i915: avoid big kmallocs on reading error state we introduce a two-pass mechanism for splitting long strings being formatted into the error-state. The first pass finds the length, and the second pass emits the right portion of the string into the accumulation buffer. Unfortunately we use the same va_list for both passes, resulting in the second pass reading garbage off the end of the argument list. As the two passes are only used for boundaries between read() calls, the corruption is only rarely seen.

2013-09-23drm/radeon: don't set default clocks for SI when DPM is disabledAlex Deucher
This is a partial revert of c6cf7777a32da874fabec4fd1c2a579f0ba4e4dd. We need to take into account the clk voltage dependencies of the board. Not doing so can lead to stability issues on certain boards if the clks exceed the levels in the dep tables. DPM already takes that into account, so for optimal performance, use DPM.

This patch adds a helper function to fetch the max clock from the voltage clock dependecy tables. Clocks above that level tend to be unstable and will require additional driver tweaks in order to work properly.
