If the command parser is not active, then it is appropriate to report it as operating at version 0 as no higher mode is supported.

And the "Broadwell Sequences for Changing CD Clock Frequency" section clarifies this further: "For CD clock 337.5 MHz, program 337 decimal. For CD clock 450 MHz, program 449 decimal.

In BXT DSI there is no regs programmed with few horizontal timings in Pixels but txbyteclkhs.. So retrieval process adds some ROUND_UP ERRORS in the process of PIXELS<==>txbyteclkhs. Actually here for the given adjusted_mode, we are calculating the value programmed to the port and then back to the horizontal timing param in pixels. This is the expected value at the end of get_config, including roundup errors. And if that is same as retrieved value from port, then retrieved (HW state) adjusted_mode's horizontal timings are corrected to match with SW state to nullify the errors.

Both execlists and legacy need to reset the context (and mode) of the GPU before we lose control of the system. By resetting the GPU, we revert back to default settings. This simplifies the life of any subsequent driver (in particular for virtualized setups) as it does not then have to try and recover from an unknown condition. As both paths need to reset for the same reason, move the reset to a common point. This unifies the resets added in a647828a (drm/i915: Also perform gpu reset under execlist mode) and 8e96d9c4 (drm/i915: reset the GPU on context fini). v2: Restrict the reset to "modern" gen (where we enable HW contexts) to try and avoid leaving the machine in an unusable state with a risky reset on older GPU. This should keep the status quo as to who performs resets (i.e. currently only GPUs with HW contexts perform a reset on shutdown).
