Add kunit test cases for drm_dp_get_vc_payload_bw() with all the DP1.4 and UHBR link configurations. v2: - List test cases in decreasing rate,lane count order matching the corresponding DP Standard tables. (Ville) - Add references to the DP Standard tables. v3: - Sort the testcases properly. v4: - Avoid 'stack frame size x exceeds limit y in drm_test_dp_mst_calc_pbn_div()' compiler warn.

The current way of calculating the pbn_div value, the link BW per each MTP slot, worked only for DP 1.4 link rates. Fix things up for UHBR rates calculating with the correct channel coding efficiency based on the link rate. v2: - Return the fractional pbn_div value from drm_dp_get_vc_payload_bw(). v3: - Fix rounding up quotient while calculating req_slots.

On UHBR links the PBN divider is a fractional number, accordingly store it in fixed point format. For now drm_dp_get_vc_payload_bw() always returns a whole number and all callers will use only the integer part of it which should preserve the current behavior. The next patch will fix drm_dp_get_vc_payload_bw() for UHBR rates returning a fractional number for those (also accounting for the channel coding efficiency correctly).

IVB Bspec says: "Frame Buffer Compression is only supported with memory surfaces of 4096 lines or less and pipe source sizes of 4096 pixels by 2048 lines or less. " so seems like we should be able to bump the offset+size limit to at least 4kx4k. Make it so.

Unfortunately even the HPD based detection added in commit cfe5bdfb ("drm/i915: Check HPD live state during eDP probe") fails to detect that the VBT's eDP/DDI-A is a ghost on Asus B360M-A (CFL+CNP). On that board eDP/DDI-A has its HPD asserted despite nothing being actually connected there :( The straps/fuses also indicate that the eDP port is present. So if one boots with a VGA monitor connected the eDP probe will mistake the DP->VGA converter hooked to DDI-E for an eDP panel on DDI-A. As a last resort check what kind of DP device we've detected, and if it looks like a DP->VGA converter then conclude that the eDP port should be ignored.

vlv_dpio_read() and vlv_dpio_write() really operate on the phy, not pipe. Passing the pipe instead of the phy as parameter is supposed to be a convenience, but when the caller has the phy, it becomes an inconvenience.

At least one TGL had regression when using u8 types for entry setup frames calculation. So, let's switch to use ints instead. intel_psr_entry_setup_frames() function expects to return u8 but since in case of error the error code -ETIME is returned. This doesn't fit into u8 and hence the return value is not as expected.

Just use a simple {} to zero initialize arrays/structs instead of the hodgepodge of stuff we are using currently.

Perform all the intel_pre_update_crtc() stuff for all pipes first, and only then do the intel_update_crtc() vblank evasion stuff for every pipe back to back. This should make it more likely that the plane updates from multiple pipes happen on the same frame (assuming the pipes are running in sync, eg. due to bigjoiner or port sync).

Split intel_update_crtc() into two parts such that the first part performs all the non-vblank evasion preparatory stuff, and the second part just does the vblank evasion stuff. For now we just call these back to back so that there is no funcitonal change.
