[Why&How] pow(a,x) is implemented as exp(x*log(a)). log(0) will crash. So return 0^x = 0, unless x=0, convention seems to be 0^0 = 1. Cc: stable@vger.kernel.org Signed-off-by:

[why] Current pipe merge and split logic only supports cases where new dc_state is allocated and relies on dc->current_state to gather information from previous dc_state. Calls to validate_bandwidth on UPDATE_TYPE_MED would cause an issue because there is no new dc_state allocated, and data in dc->current_state would be overwritten during pipe merge. [how] Only allow validate_bandwidth when new dc_state space is created. Signed-off-by:

[Why] with eDP + DP, each display use one pipe. after DP unplugged, eDP switch from one pipe to two pipes -- pipe split. dpp1_cm_set_regamma_pwl will be executed too. The duration from switch single pipe to dual pipes is a little long which could let eDP enter PSR mode. upon two pipes for eDP are setup, eDP PHY is disabled. front pipe is not really running to fetch data from frame buffer. i.e., dchubp is not in normal working status. execution of hubbub1_wm_change_req_wa may cause p-state warning. [How] disable eDP PSR before dc_commit_state. psr is disabled when execute hubbub1_wm_change_req_wa. Signed-off-by:
