2020-06-30drm/amd/display: Only revalidate bandwidth on medium and fast updatesNicholas Kazlauskas
[Why] Changes that are fast don't require updating DLG parameters making this call unnecessary. Considering this is an expensive call it should not be done on every flip. DML touches clocks, p-state support, DLG params and a few other DC internal flags and these aren't expected during fast. A hang has been reported with this change when called on every flip which suggests that modifying these fields is not recommended behavior on fast updates.

For AF_PACKET injection, we need to support its call chain of: packet_sendmsg -> packet_snd -> packet_parse_headers -> dev_parse_header_protocol -> parse_protocol Without a valid parse_protocol, this returns zero, and the tun driver then gives userspace bogus values that it can't deal with.

2020-06-30drm/i915/fbc: Reduce fbc1 compression interval to 1 secondVille Syrjälä
The default fbc1 compression interval we use is 500 frames. That translates to over 8 seconds typically. That's rather excessive so let's drop it to 1 second. The hardware will not attempt recompression unless at least one line has been modified, so a shorter compression interval should not cause extra bandwidth use in the purely idle scenario. Of course in the mostly idle case we are possibly going to recompress a bit more. Should really try to find some kind of sweet spot to minimize the energy usage...

2020-06-30drm/i915/fbc: Fix fence_y_offset handlingVille Syrjälä
The current fence_y_offset calculation is broken. I think it more or less used to do the right thing, but then I changed the plane code to put the final x/y source offsets back into the src rectangle so now it's just subtraacting the same value from itself. The code would never have worked if we allowed the framebuffer to have a non-zero offset. Let's do this in a better way by just calculating the fence_y_offset from the final plane surface offset. Note that we don't align the plane surface address to fence rows so with horizontal panning there's often a horizontal offset from the fence start to the surface address as well. We have no way to tell the hardware about that so we just ignore it. Based on some quick tests the invlidation still happens correctly. I presume due to the invalidation nuking at least the full line (or a segment of multiple lines).

2020-06-30drm/i915: Skip stale object handle for debugfs per-file-statsChris Wilson
As we close a handle GEM object, we update the drm_file's idr with an error^W NULL pointer to indicate the in-progress closure, and finally removing it. If we read the idr directly, we may then see an invalid object pointer, and in our debugfs per_file_stats() we therefore need to protect against the entry being invalid.

2020-06-30drm: panel: simple: Warn in case of incorrect bus format for LVDS panelsLaurent Pinchart
Only the MEDIA_BUS_FMT_RGB666_1X7X3_SPWG, MEDIA_BUS_FMT_RGB888_1X7X4_SPWG and MEDIA_BUS_FMT_RGB888_1X7X4_JEIDA bus formats are valid for LVDS panels. Warn at probe time to catch the common mistake of using an incorrect format, as well as discrepancies between the bus format and the reported bpc.
