From: Wenjing Liu <[email protected]> [why] There are some new changes for HDCP2 firmware locality check. The implementation doesn't perfectly fit the intended design and clarity.
1. Clarify and consolidate variable responsibilities. The previous implementation introduced the following variables: - config.ddc.funcs.atomic_write_poll_read_i2c (optional pointer) - hdcp->config.ddc.funcs.atomic_write_poll_read_aux (optional pointer) - hdcp->connection.link.adjust.hdcp2.force_sw_locality_check (bool) - hdcp->config.debug.lc_enable_sw_fallback (bool) - use_fw (bool) They will be used together to determine two operations: - Whether to use FW locality check - Whether to use SW fallback on FW locality check failure The refactor streamlines this by introducing two variables in the hdcp2 link adjustment, while ensuring function pointers are always assigned and remain independent from policy decisions: - use_fw_locality_check (bool) -> true if fw locality should be used. - use_sw_locality_fallback (bool) -> true to reset use_fw_locality_check back to false and retry on fw locality check failure. 2. Mixed meanings of l_prime_read transition input l_prime_read originally means if l_prime is read when sw locality check is used. When FW locality check is used, l_prime_read means if lc init write, l prime poll and l_prime read combo operation is successful. The mix of meanings is confusing. The refactor introduces a new variable l_prime_combo_read to isolate the second meaning into its own variable. 3. Missing specific error code on firmware locality error. The original change reuses the generic DDC failure error code when firmware fails to return locality check result. This is not ideal as DDC failure indicates an error occurred during an I2C/AUX transaction. FW locality failure could be caused by polling timeout in firmware or failure to acquire firmware access. Which sits at a higher level of abstraction above DDC hardware. An incorrect error code could mislead the debug into a wrong direction. 4. Adding macros to simplify the process of adding new error codes. Currently, to add an error code, the developer needs to add both the enum and the string translation. This is error prone and can lead to inconsistencies. The refactor adds a macro to automatically add the string translation based on the enum. 5. Correcting misplaced comments. The previous implementation of the firmware locality check resulted in some comments in hdcp2_transition being incorrectly positioned. This refactor relocates those comments to their appropriate locations for better clarity.
