[Why] Current code does not guarantee the correct endianness of memory being copied to fw, specifically in the case where cpu isn't little endian. [How] Windows and Diags are always little endian, so we define a macro that does nothing. Linux already defines this macro and will do the correct endianness conversion. Signed-off-by:

[why] We have seen a green screen after resume from suspend in a Raven system connected with two displays (HDMI and DP) on X based system. We noticed that this issue is related to bad DCC metadata from user space which may generate hangs and consequently an underflow on HUBP. After taking a deep look at the code path we realized that after resume we try to restore the commit with the DCC enabled framebuffer but the framebuffer is no longer valid. [how] This problem was only reported on Raven based system and after suspend, for this reason, this commit adds a new parameter on fill_plane_dcc_attributes() to give the option of disabling DCC programmatically. In summary, for disabling DCC we first verify if is a Raven system and if it is in suspend; if both conditions are true we disable DCC temporarily, otherwise, it is enabled. Co-developed-by:

[Why] We expect to be able to perform immediate flipping without having to recalculate and update all the watermarks. There are certain usecases today (1080p @ 90deg, 2160p @ 90deg) such that we get a urgency value of 0 for frac_urg_bw_flip because we're explicitly passing in a value of "false" for requiring immediate flip support into the DLG calculation. [How] Always pass in true into the calculation. With this we get a correct non-zero value for frac_urg_bw_flip. Signed-off-by:

[why] Optc needs to know if timing is enabled with ODM or DSC before computing crc. Otherwise value computed will be inaccurate. Before this change, the CRC computed without ODM is not equal to the CRC computed with ODM for the same timing. This is unexpected as we are driving the same timing despite of the underlaying hardware setup to achieve it. This is caused by missing hardware programming sequence to support it.

[Why] As it stands, psr has feature flags in dm, stream, and link. Most are not defined well enough, and different dm layers have different uses for these same flags. [How] We define a new structure called psr_settings in dc_link that will hold the following psr feature flags: psr_feature_enable - psr is supported psr_allow_active - psr is currently active psr_version - internal psr version supported psr_frame_capture_indication_req psr_sdp_transmit_line_num_deadline The last two flags were moved out of the power module for the purposes of consolidating psr flags. Their use is already well-defined. Psr caps reported by sink will also be stored in dc_link, in dpcd_caps.psr_caps. Signed-off-by:
