dGFX has local memory so it does not have aperture or support CPU fences but even for iGFX it have a small number of fences. As replacement for fences to track frontbuffer modifications by CPU we have a software tracking that is already in used by FBC and PSR. PSR don't support fences so it shows that this tracking is reliable. So lets make fences a nice-to-have to activate FBC for GEN9+, this will allow us to enable FBC for dGFXs and iGFXs even when there is no available fence. We do not set fences to rotated planes but FBC only have restrictions against 16bpp, so adding it here. Also adding a new check for the tiling format, fences are only set to X and Y tiled planes but again FBC don't have any restrictions against tiling so adding linear as supported as well, other formats should be added after tested but IGT only supports drawing in thse 3 formats. intel_fbc_hw_tracking_covers_screen() maybe can also have the same treatment as fences but BSpec is not clear if the size limitation is for hardware tracking or general use of FBC and I don't have a 5K display to test it, so keeping as is for safety. v2: - Added tiling and pixel format rotation checks - Changed the GEN version not requiring fences to 11 from 9, DDX needs some changes but it don't have support for GEN11+ v3: - Changed back to GEN9+ - Moved GEN test to inside of tiling_is_valid() v4: - moved rotation check to its own functions v5: - renamed rotations_is_valid to rotation_is_valid - moved pre-g4x rotation check to rotation_is_valid() Cc: Daniel Vetter <daniel.vetter@intel.com> Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

On Ivybridge, we can go lower than rc6 to rc6p. And this is required for Ivybridge to hit the same minimum power consumption as rc6 on other platforms, so make it so. v2: Update selftest to include all rc6 residency counters Note that Andi did mention that we should be converting the magic numbers into opaque magic macros, so if they ever get reused (unlikely given only Ivybridge used the extra modes) we'll need to pay back the technical debt.

It is strictly sufficient to only delay the intel_engine_pm_put from the context barrier (and not from the context exit) in order to prevent the gem_exec_nop contention.

It looks like some callers expect a non-volatile object, that they do not want the contents of the pages lost if they happen to not be looking at it. The shrinker however sees that we mark the pages as DONTNEED and believes that it can freely reap them. However, since the huge object use plain pages, they cannot be swapped out as they have no backing storge, and the only way we can shrink them is by discarding the contents. In light of the callers wanting to keep the contents around, both IS_SHRINKABLE and marking the pages as volatile are incorrect. If we drop the IS_SHRINKABLE flag we avoid the immediate issue of the shrinker accidentally removing valuable content. We will have to remember that a huge object is not suitable for exercising the shrinker interaction -- although we can introduce a shrinkable one if we require. Signed-off-by:

Keep the engine-pm awake until the next jiffie, to avoid immediate ping-pong under moderate load. (Forcing the idle barrier excerbates the moderate load, dramatically increasing the driver overhead.)

Few edp panels like Sharp is triggering short and long hpd pulse after panel is getting powered off. Currently driver is already ignoring long pulse for eDP panel but in order to process the short pulse, it turns on the VDD which requires panel power_cycle_delay + panel_power_on_delay these delay on Sharp panel introduced the responsiveness overhead of 800ms in the modeset sequence and as well is in suspend sequence. Ignoring any short pulse if panel is powered off. FIXME: It requires to wait for panel_power_off delay in order to check the panel power status due to pps_lock because panel triggers short pulse immediately after writing PP_OFF to PP_CTRL register and wait_panel_off waits for panel_power_off delay with pps_lock held. This still creates responsiveness overhead of panel_power_off delay. v2: - checking vdd along with panel power to ignore the hpd. [Jani,Ville] v3: - safer side check to ignore the long hpd when eDP have power, adding type of hpd to debug log. [Jani] Signed-off-by:

We only consider crtc_state->enable when initially calculating plane visibility. Later on we try to override the plane's state to invisible if the crtc is in DPMS off state (crtc_state->active==false). Unfortunately the code doing that only updates the plane_state.visible flag and the crtc_state.active_planes bimask, but forgets to update some of the other plane bitmasks stored in the crtc_state. Namely crtc_state.nv12_planes is left set up based on the original visibility check which makes icl_check_nv12_planes() pick a slave plane for the flagged plane in the bitmask. Later on we hit the watermark code which sees a plane with a slave assigned and it then makes the logical assumption that the master plane must itself be visible. Since the master's plane_state.visible flag was already cleared we get a WARN. Fix the problem by clearing all the plane bitmasks for DPMS off. This is more or less the wrong approach and instead we should calculate all the plane related state purely based crtc_state->enable (to guarantee that the subsequent DPMS on can't fail). However in the past we definitely had some roadblocks to making that happen. Not sure how many are left these days, but let's stick to the current approach since it's a much simpler fix to the immediate problem (the WARN). v2: Keep the visible=false, it's important (Rodrigo) Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by:

This fixes a problem found on the MacBookPro 2017 Retina panel. The panel reports 10 bpc color depth in its EDID, and the firmware chooses link settings at boot which support enough bandwidth for 10 bpc (324000 kbit/sec = multiplier 0xc), but the DP_MAX_LINK_RATE dpcd register only reports 2.7 Gbps (multiplier value 0xa) as possible, in direct contradiction of what the firmware successfully set up. This restricts the panel to 8 bpc, not providing the full color depth of the panel. This patch adds a quirk specific to the MBP 2017 15" Retina panel to add the additiional 324000 kbps link rate during edp setup. Link to previous discussion of a different attempted fix with Ville and Jani: https://patchwork.kernel.org/patch/11325935/ v2: Follow Jani's proposal of defining quirk_rates[] instead of just appending 324000. This for better clarity. v3: Rebased onto current drm-tip, as of 16-March-2020. Adapt to new edid_quirks parameter of drm_dp_has_quirk(). Signed-off-by:
