2019-03-27drm/i915: Reject Yf tiling for HDR formats, v2.Maarten Lankhorst
This was missing in the original addition of those formats, but in PLANE_SIZE description it's mentioned that 8 cpp formats are not valid with Yf tiling. Reject this case properly. Also reject Y21x Yf tiling support this is also not supported. Changes since v1: - Reject Y21x as well.

2019-03-27drm/i915: Handle YUV subpixel support betterMaarten Lankhorst
Y41x formats is a 4:4:4 format, so it can be addressed with pixel level accuracy. Meanwhile it seems that while rotating YUYV 4:2:2 formats need a multiple of 2 for width and height, otherwise corruption occurs. For YUV 4:2:2, the spec says that w/h should always be even, but we get away with odd height while unrotated. When rotating it seems corruption occurs with an odd x/y, and w/h should always be even. Just to be completely paranoid, reject odd x/y w/h when rotating 90/270.

2019-03-27drm/i915: Drop new chunks of context creation ABI (for now)Chris Wilson
The intent was to expose these as part of the means to perform full context recovery (though not the SINGLE_TIMELINE, that is for later and just sucked as collateral damage). As that requires a couple more patches to complete the series, roll back the earlier chunks of ABI for an intervening PR. We keep all the internals intact and under selftests.

2019-03-27drm/i915: Disable semaphore on vGPU for nowZhenyu Wang
This is to disable semaphore usage when on vGPU for now. Unfortunately GVT-g hasn't fully enabled semaphore usage yet, so current guest with semaphore use would cause vGPU failure. Although current semaphore failure with vGPU can be simply resolved by allowing cmd parser to accept MI_SEMAPHORE_WAIT command with address audit, we're checking general usage of semaphore and how we should handle it properly for virtualization in consider of function and security concern. So we decide to request to disable it for now in guest driver. Once GVT could support it, we would add new compat bit to turn it on.

2019-03-27drm/i915: Update TRANS_MSA_MISC for fastsetsVille Syrjälä
Update the DP MSA MISC bits for fastsets. This is needed when we change between limited and full range RGB output. On HSW+ changing limited_range does not currently result in a full modeset since we have don't have the readout code for it (for DP we could, and probably should, readout from TRANS_MSA_MISC itself, for HDMI we would have to rely on the infoframe). So the PIPE_CONF_CHECK() is only performed for pre-HSW platforms. That means any change in the value will result in a fastset instead. Fortunately there is no prohibition to changing TRANS_MSA_MISC dynamically, so it looks like we can legally do fastsets for this.

Iterate over child devices instead of ports in parse_ddi_ports() to initialize ddi_port_info. We'll eventually need to decide some stuff based on the child device order, which may be different from the port order. As a bonus, this allows better abstractions for e.g. dvo port mapping. There's a subtle change in the DDC pin and AUX channel sanitization as we change the order. Otherwise, this should not change behaviour.

2019-03-25drm/i915: Disable C3 when enabling vblank interrupts on i945gmVille Syrjälä
The AGPBUSY thing doesn't work on i945gm anymore. This means the gmch is incapable of waking the CPU from C3 when an interrupt is generated. The interrupts just get postponed indefinitely until something wakes up the CPU. This is rather annoying for vblank interrupts as we are unable to maintain a steady framerate unless the machine is sufficiently loaded to stay out of C3. To combat this let's use pm_qos to prevent C3 whenever vblank interrupts are enabled. To maintain reasonable amount of powersaving we will attempt to limit this to C3 only while leaving C1 and C2 enabled. v2: Use READ_ONCE() (Chris) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=30364 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190322180804.3300-1-ville.syrjala@linux.intel.com Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>

Since commit b7137e0cf1e5 ("drm/i915: Defer enabling rc6 til after we submit the first batch/context"), intel_suspend_gt_powersave() has been a no-op. As we still do not need to do anything explicitly on suspend (we do everything required on idling), remove the defunct function.
