2019-03-26drm/i915: take a reference to uncore in the engine and use itDaniele Ceraolo Spurio13-218/+243
A few advantages: - Prepares us for the planned split of display uncore from GT uncore - Improves our engine-centric view of the world in the engine code and allows us to avoid jumping back to dev_priv. - Allows us to wrap accesses to engine register in nice macros that automatically pick the right mmio base.

2019-03-26drm/fbdev: Make skip_vt_switch the defaultDaniel Vetter6-7/+4
KMS drivers really should all be able to restore their display state on resume without fbcon helping out. So make this the default. Since I'm not entirely foolish, make it only a default, which drivers can still override. That way when the inevitable regression report happens I can fix things up with a one-liner plus FIXME comment that someone should fix up the suspend/resume code in that driver. But at least all new drivers won't be broken by accident as soon as you turn off fbcon because "suspend/resume worked when I tested it". v2: Keep this for radeon because of commit 18c437caa5b18a235dd65cec224eab54bebcee65 Author: Alex Deucher <[email protected]> Date: Tue Nov 14 17:19:29 2017 -0500 Revert "drm/radeon: dont switch vt on suspend" Thanks to Michel Dänzer for pointing this one out.

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.

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.

2019-03-25drm: Fix drm_release() and device unplugNoralf Trønnes2-9/+3
If userspace has open fd(s) when drm_dev_unplug() is run, it will result in drm_dev_unregister() being called twice. First in drm_dev_unplug() and then later in drm_release() through the call to drm_put_dev(). Since userspace already holds a ref on drm_device through the drm_minor, it's not necessary to add extra ref counting based on no open file handles. Instead just drm_dev_put() unconditionally in drm_dev_unplug(). We now have this: - Userpace holds a ref on drm_device as long as there's open fd(s) - The driver holds a ref on drm_device as long as it's bound to the struct device When both sides are done with drm_device, it is released.

If the downscaling fails and we end up with a best_depth of 0, then ignore it. This actually works around a cascade of failure, but it the simplest fix for now. The scaling patch broke the udl driver, as the udl driver doesn't expose planes at all, so gets the two default 32-bit formats, but the udl driver then ask for 16bpp fbdev, and the scaling code falls over. This fixes the udl driver since the scaled depth support was added.

2019-03-24drm/i915: Remove defunct intel_suspend_gt_powersave()Chris Wilson3-18/+0
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.

2019-03-24drm/i915: always pin hw_id for GVT contextZhenyu Wang1-0/+7
Initially found issue with closed context debug check when pin hw_id for GVT context, looks we should always pin hw_id for that as GVT context is fixed for each vGPU life cycle, and we'd also like to get pinned hw_id e.g for perf reason, etc. Cc: Chris Wilson <[email protected]> Signed-off-by: Zhenyu Wang <[email protected]> Reviewed-by: Chris Wilson <[email protected]> Signed-off-by: Chris Wilson <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
