Depending upon one module option to be sanitized (through USES_PPGTT) for the other is a bit too fragile for my taste. At least WARN about this.

GEN8 brings an expansion of the HW contexts: "Logical Ring Contexts". These expanded contexts enable a number of new abilities, especially "Execlists". The macro is defined to off until we have things in place to hope to work. v2: Rename "advanced contexts" to the more correct "logical ring contexts". v3: Add a module parameter to enable execlists. Execlist are relatively new, and so it'd be wise to be able to switch back to ring submission to debug subtle problems that will inevitably arise. v4: Add an intel_enable_execlists function. v5: Sanitize early, as suggested by Daniel. Remove lrc_enabled.

Some legacy HW context code assumptions don't make sense for this new submission method, so we will place this stuff in a separate file. Note for reviewers: I've carefully considered the best name for this file and this was my best option (other possibilities were intel_lr_context.c or intel_execlist.c). I am open to a certain bikeshedding on this matter, anyway. And some point in time, it would be a good idea to split intel_lrc.c/.h even further, but for the moment just shove everything together. v2: Change to intel_lrc.c v3: Squash together with the header file addition Signed-off-by:

Part of the pre-validation for an execbuffer call is that there is at least one object in the execlist. As we bail if we fail to lookup any object, we can be sure that after the eb_lookup_vma() there is at least one object in the vma list and so we do not need to assert. Signed-off-by:

We have an implementation requirement that precludes the user from requesting a ggtt entry when the device is operating in ppgtt mode. Move the current check from inside the execbuffer object collation to the prevalidation phase. v2: Roll both invalid flags checks into one Signed-off-by:

Based upon a hunk from a patch from Chris Wilson, but augmented to: - Process the batch in the full ppgtt vm so that self-relocations match again with userspace's expectations.. - Add a comment why plain pin for the global gtt binding is safe at that point. v2: Drop local bind_vm variable (Chris). v3: Explain why this works despite the lack of proper active tracking for the ggtt batch vma.

Adapt the macro so that we can pass either the struct drm_device or the struct drm_i915_private pointers and get the answer we want. Over time, my plan is to convert all users over to using drm_i915_private and so trimming down the pointer dance. Having spent a few hours chasing that goal and achieved over 8k of object code saving, it appears to be a worthwhile target. This interim macro allows us to slowly convert over. Signed-off-by:

Move the decision on whether we need to have a mappable object during execbuffer to the fore and then reuse that decision by propagating the flag through to reservation. As a corollary, before doing the actual relocation through the GTT, we can make sure that we do have a GTT mapping through which to operate. Note that the key to make this work is to ditch the obj->map_and_fenceable unbind optimization - with full ppgtt it doesn't make a lot of sense any more anyway. v2: Revamp and resend to ease future patches. v3: Refresh patch rationale References: https://bugs.freedesktop.org/show_bug.cgi?id=81094Signed-off-by:

If an object is not bound into the global GTT, then it cannot be accessed via the GTT. This restores the original code that was muddled by ppGTT. In the process, we remove a WARN that had long outlived its usefulness and was simply being coded around instead. Signed-off-by:

I keep telling myself that those tables aren't great because their size is the number of dwords we need to program and not the number of entries (number of dwords = number of entries * 2). And... I got it wrong when I refactored the code. Fortunately, it was only wrong when the VBT table (or the code parsing it) is itself erroneous. Long story short, it shouldn't matter, but still, there's a potential array overflow and random programming of the DDI translation tables. Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by:

Make the intel_{enable,disable}_primary_hw_plane() simply call .update_primary_plane(), thus eliminating the rmw from these functions which should help the poor old 830M. Now we can also remove the .update_primary_plane() from the .crtc_enable() hooks because we end up calling it via intel_crtc_enable_planes()->intel_enable_primary_hw_plane(). This also has the nice benefit of making primary planes a bit closer to the way we handle sprite planes during modesets. v2: Just write 0 to DSPCNTR and DSPSURF/DSPADDR if the plane is (to be) disabled. Quicker, and more importantly avoids an oops when fb==NULL due to BIOS fb takeover failure.

Move the entire DSPCNTR register setup into the .update_primary_plane() functions. That's where it belongs anyway and it'll also help 830M which has the extra problem that plane registers reads will return the value latched at the last vblank, not the value that was last written. Also move DSPPOS and DSPSIZE setup there. v2: Don't move variable initialization to avoid churn later Reviewed-by:

adj was defined as u8. The issue is last_adj can be negative and adj is initialized with: adj = dev_priv->rps.last_adj; and we were also happily doing things like: if (adj < 0) (thank static analysers!) v2: Make new_delay an int in case we overflow the u8 in the intermediate computations. new_delay will get clamped at the end anyway.

If there are pending page flips when the fd gets closed those page flips may have events associated to them. When the page flip eventually completes it will queue the event to file_priv->event_list, but that may be too late and file_priv->event_list has already been cleaned up. Thus we leak a bit of kernel memory in the form of the event structure. To avoid such problems clear out such pending events from intel_crtc->unpin_work at ->preclose(). Any event that already made it to file_priv->event_list will get cleaned up by the drm_release_events() a bit later. We can ignore the file_priv->event_space accounting since file_priv is going away. This is already how drm core deals with pending vblank events, which are maintained by the drm core. What saves us from a total disaster (ie. dereferencing and alrady freed file_priv) is the fact that the fb descruction triggers a modeset and there we wait for pending flips. Signed-off-by:

It looks like frobbing the cmnreset line on pne PHY disturbs the other PHY on chv. The result is a black screen. On HDMI it's just a flash of black, but DP usually falls over and can't get back up. As a workaround set up the power domains so that both common lane wells power up and down together. I also tried leaving the cmnreset deasserted even the if the power well goes down but that didn't seem acceptable to the PHY. Reviewed-by:

The VLV/CHV DDL registers are uniform, and neatly enough the register offsets are sane so we can easily unify them to a single set of defines and just pass the pipe as the parameter to compute the register offset. Note that we now fill out the drain latency for pipe C on CHV which we didn't do before. The rest of the pipe C watermarks are still untouched but that will be remedied later by adding a proper cherryview_update_wm() function. v2: Add a note about CHV pipe C changes (Paulo) Reviewed-by:

Add defines for all the watermark registers on modernish gmch platforms. VLV has increased the number of bits available for certain watermaks so expand the masks appropriately. Also vlv and chv have added some extra FW registers. Not sure what happened on chv because a new register called FW9 is now at the offset where FW7 was on vlv, while FW7 and FW8 (another new register) have been moved off somewhere else. Oh well, well just need two defines for FW7 then. v2: Fix DSPHOWM1 offset (Paulo) Reviewed-by:
