As the ppgtt for execlists is tightly coupled to the executing context, and not switch separately, we no longer use the ppgtt->switch_mm hooks on gen8+. Remove them. References: 79e6770c ("drm/i915: Remove obsolete ringbuffer emission for gen8+") Signed-off-by:

PLLs are the source clocks for the DDIs so in order to determine the ddi clock we need to check the PLL configuration. This gets a little tricky for ICL since there is no register bit that maps directly to the link clock. So this patch creates a separate function in intel_dpll_mgr.c to obtain the write array PLL Params and compares the set pll_params with the table to get the corresponding link clock. v2: - Fix the encoder type check (DK). - Improve our error checking, return a sane value (Mika, Paulo). - Fix table entries (Paulo).

Add and enum for TC ports and auxiliary functions to handle them. Icelake brings a lot of registers and other things that only apply to the TC ports and are indexed starting from 0, so having an enum for tc_ports that starts at 0 really helps the indexing.

Let's not take any chances by using a shortcut to mark the objects as in the CPU domain upon freezing (all pages will be written to disk and so on restore all objects will start from the CPU domain). Currently, we simply mark the objects as being in the CPU domain, bypassing the flushes. Let's call the full domain transfer function so that we have less special case code (and symmetry with the suspend path) even though it will be mostly redundant. Signed-off-by:

As we have already suspended the device, this should be a no-op except for marking that all writes are indeed complete. The downside is that we then have to walk all the lists of objects for what should be a no-op (in some cases they will be mmio read to ensure the GGTT writes are indeed flushed, and clflushes to ensure that cpu writes are in memory). It seems prudent and the safer course for us to ensure all writes are flushed to memory before suspend. Signed-off-by:

Set up the SKL+ scaler initial phase registers correctly. Otherwise we start fetching the data from the center of the first pixel instead of the top-left corner, which obviously then leads to right/bottom edges replicating data excessively as the data runs out half a pixel too soon.

Like we do for encoder let's make the plane->get_hw_state() return the pipe to which the plane is currently attached. We don't currently allow planes to move between the pipes, but perhaps one day we will. In either case this makes the code more uniform and perhaps makes intel_plane_mapping_ok() slightly more clear. Note that for i965 and g4x planes A and B still have pipe select bits but they're hardwired to pipe A and B respectively. This means we can safely interpret those bits just like on gen2/3. This allows the same readout code work for plane C (which can still be assigned to eiter pipe on i965) should we ever expose it. g4x no longer allows moving the cursor planes between the pipes, but the pipe select bits can still be set in the register. Thus we have to ignore those bits. OTOH i965 still allows the cursors to move between pipes thus we have to trust the bits there. Signed-off-by:

On resume, we have to rewrite all the PDE entries for gen7 ppgtts. If we switch on full-ppgtt, there is then one address space with no PDE, the GGTT. Currently under aliasing-ppgtt, the GGTT address space does have an associated ppgtt and so the restore works just fine. We would have a similar problem if we tried disabling aliasing-ppgtt (i915.enable_ppgtt=0). So skip the empty ppgtt, as being non-existent it doesn't need restoring. Signed-off-by:

During testing we encounter a conflict between SUSPEND_TEST_DEVICES and disabling reset (gem_eio/suspend). This results in the device continuing on without being reset, but since it has gone through HW sanitization to account for the suspend/resume cycle, we have to assume the device has been reset to its defaults. A simple way around this is to skip the sanitize phase for SUSPEND_TEST_DEVICES by moving it to suspend-late. Signed-off-by:

During suspend we want to flush out all active contexts and their rendering. To do so we queue a request from the kernel's context, once we know that request is done, we know the GPU is completely idle. To speed up that switch bump the GPU clocks. Switching to the kernel context prior to idling is also used to enforce a barrier before changing OA properties, and when evicting active rendering from the global GTT. All cases where we do want to race-to-idle. v2: Limit the boosting to only the switch before suspend. v3: Limit it to the wait-for-idle on suspend. Signed-off-by:

We can reduce our exposure to random neutrinos by resting on the kernel context having flushed out the user contexts to system memory and beyond. The corollary is that we then we require two passes through the idle handler to go to sleep, which on a truly idle system involves an extra pass through the slow and irregular retire work handler.

Since we use i915_gem_find_active_request() from inside intel_engine_dump() and may call that at any time, we do not guarantee that the engine is paused nor that the signal kthreads and irq handler are suspended, so we cannot assert that the breadcrumb doesn't advance and that the irq hasn't happened on another CPU signaling the request we believe to be idle. The second assert removed (that request->engine == engine) remains valid, but is now more rigorously checked during retirement.

DPCD 2009h "Synchronization latency in sink" has bits that tell us the maximum number of frames sink can take to resynchronize to source timing when exiting PSR. More importantly, as per eDP 1.4b, this is the "Minimum number of frames following PSR exit that the Source device needs to wait for PSR entry." We currently use this value only to setup the number frames to wait before PSR2 selective update. But, based on the above description it makes more sense to use this to configure idle frames for both PSR1 and and PSR2. This will ensure we wait the required number of frames before activation whether it is PSR1 or PSR2. The minimum number of idle frames remains 6, while allowing sink synchronization latency and VBT to increase this value. This also solves the flip-flop between sink and source frames that I noticed on my Thinkpad X260 during PSR exit. This specific panel has a value of 8h, which according to the spec means the "Source device must wait for more than eight active frames after PSR exit before initiating PSR entry. (In this case, should be provided by the panel supplier.)" VBT however has a value of 0.

Let's suppress the underruns around every modeset sequence instead of trying to avoid it. Planes are disabled at this point anyway so we don't really gain anything from keeping the underrun reporting enabled. Also for PCH ports we already suppress all underruns here anyway so trying avoid it for the CPU eDP doesn't seem all that important. Maybe this gets rid of some lingering spurious underruns?

VBT seems to have some bits to tell us whether the internal LVDS port has something hooked up. In theory one might expect the VBT to not have a child device for the LVDS port if there's no panel hooked up, but in practice many VBTs still add the child device. The "LVDS config" bits seem more reliable though, so let's check those. So far we've used the "LVDS config" bits to check for eDP support on ILK+, and disable the internal LVDS when the value is 3. That value is actually documented as "Both internal LVDS and SDVO LVDS", but in practice it looks to mean "eDP" on all the ilk+ VBTs I've seen. So let's keep that interpretation, but for pre-ILK we will consider the value 3 to also indicate the presence of the internal LVDS. Currently we have 25 DMI matches for the "no internal LVDS" quirk. In an effort to reduce that let's toss in a WARN when the DMI match and VBT both tell us that the internal LVDS is not present. The hope is that people will report a bug, and then we can just nuke the corresponding entry from the DMI quirk list. Credits to Jani for this idea. v2: Split the basic int_lvds_support thing to a separate patch (Jani) v3: Rebase v4: Limit this to VBT version >= 134 Cc: Jani Nikula <jani.nikula@intel.com> Cc: Ondrej Zary <linux@rainbow-software.org> Signed-off-by:
