2013-10-18drm/radeon: rework audio optionAlex Deucher
In 3.12 I changed audio to be enabled by default, but you still had to turn it on via xrandr. This was confusing to users so change it to minic the previous behavior: - audio option is set to -1 (auto) by default which is the current 3.12 behavior (audio is enabled but requires xrandr to turn it on). - if audio = 1, the audio is enabled without needing to mess with xrandr (previous behavior) - audio = 0 disables audio It retains the new feature of allowing the user to enable audio on the fly with xrandr, but turns audio on automatically if radeon.audio=1 is set which is what most users expect.

2013-10-18drm/i915: Disable GGTT PTEs on GEN6+ suspendBen Widawsky
Once the machine gets to a certain point in the suspend process, we expect the GPU to be idle. If it is not, we might corrupt memory. Empirically (with an early version of this patch) we have seen this is not the case. We cannot currently explain why the latent GPU writes occur. In the technical sense, this patch is a workaround in that we have an issue we can't explain, and the patch indirectly solves the issue. However, it's really better than a workaround because we understand why it works, and it really should be a safe thing to do in all cases. The noticeable effect other than the debug messages would be an increase in the suspend time. I have not measure how expensive it actually is. I think it would be good to spend further time to root cause why we're seeing these latent writes, but it shouldn't preclude preventing the fallout. NOTE: It should be safe (and makes some sense IMO) to also keep the VALID bit unset on resume when we clear_range(). I've opted not to do this as properly clearing those bits at some later point would be extra work. v2: Fix bugzilla link Bugzilla: http://bugs.freedesktop.org/show_bug.cgi?id=65496 Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=59321 Tested-by: Takashi Iwai <tiwai@suse.de> Tested-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Tested-By: Todd Previte <tprevite@gmail.com> Cc: stable@vger.kernel.org Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

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.

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."

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(). The regression was introduced in commit 7dcd2677ea912573d9ed4bcd629b0023b2d11505 Author: Konstantin Khlebnikov <khlebnikov@openvz.org> Date: Wed Jul 17 10:22:58 2013 +0400 drm/i915: fix long-standing SNB regression in power consumption after resume though there was no good reason to initialize the static vlv_work from another delayed work to begin with (especially since this will happen multiple times).

2013-09-28drm/msm: deal with mach/iommu.h removalRob Clark
We still need an API exported by msm iommu driver (but not visible in any public header anymore). For now, just declare the prototype ourselves, but when msm iommu driver provides a better option, use that instead. Signed-off-by: Rob Clark <robdclark@gmail.com>

The include file has been removed and the file does not need it anyway, so remove it. Fixes a compile error. Signed-off-by: Joerg Roedel <joro@8bytes.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

2013-09-26drm/i915: Fix up usage of SHRINK_STOPDaniel Vetter
In commit 81e49f811404f428a9d9a63295a0c267e802fa12 Author: Glauber Costa <glommer@openvz.org> Date: Wed Aug 28 10:18:13 2013 +1000 i915: bail out earlier when shrinker cannot acquire mutex SHRINK_STOP was added to tell the core shrinker code to bail out and go to the next shrinker since the i915 shrinker couldn't acquire required locks. But the SHRINK_STOP return code was added to the ->count_objects callback and not the ->scan_objects callback as it should have been, resulting in tons of dmesg noise like shrink_slab: i915_gem_inactive_scan+0x0/0x9c negative objects to delete nr=-xxxxxxxxx Fix discusssed with Dave Chinner.
