2021-08-25drm/i915/dg2: Memory latency values from pcode must be doubledMatt Roper
The memory latency values returned by pcode on DG2 are in units of "2 usec" rather than 1 usec on all other platforms. I.e., we need to double the value returned by pcode to obtain the true latency value. The bspec wording here was a bit ambiguous as to whether it wanted us to multiply or divide the pcode value by two, but we confirmed offline with the hardware team that we need to double the value the pcode gives us; this change is intended to support a larger range of potential latency values.

2021-08-20drm/i915/irq: reduce inlines to reduce header dependenciesJani Nikula
Presumably if the compiler is smart, it does not generate an extra function call to the update functions that are now static.

2021-08-18drm/i915/adl_p: Also disable underrun recovery with MSOMatt Roper
One of the cases that the bspec lists for when underrun recovery must be disabled is "COG;" that note actually refers to eDP multi-segmented operation (MSO). Let's ensure the this additional restriction is honored by the driver.

2021-08-18drm/i915/dp: return proper DPRX link training resultLee Shawn C
After DPRX link training, intel_dp_link_train_phy() did not return the training result properly. If link training failed, i915 driver would not run into link train fallback function. And no hotplug uevent would be received by user space application.

2021-08-16drm/i915/display: Fix sel fetch plane offset calculationJosé Roberto de Souza
skl_calc_main_surface_offset() is used to calculate an aligned plane surface address considering the inner framebuffer x and y offset. It can not be used by selective fetch functions becase there is no PLANE_SEL_FETCH_SURF. So the PLANE_SEL_FETCH_OFFSET.y should only be PLANE_OFFSET.y + damaged_area_within_plane.y1. This fixes glitches seen in fbcon caused by typing something in the terminal.
