Analyze and fix the following issue in the Linux kernel code: interconnect: qcom: Add support for mask-based BCMs
Problem Details: Some BCMs aren't directly associated with the data path (i.e. ACV) and therefore don't communicate using BW. Instead, they are simply enabled/disabled with a simple bit mask. Add support for these. Origin commit retrieved from: https://git.codelinaro.org/clo/la/kernel/msm-5.15/-/commit/2d1573e02069981...

Analyze and fix the following issue in the Linux kernel code: igc: Handle already enabled taprio offload for basetime 0
Problem Details: Since commit e17090eb2494 ("igc: allow BaseTime 0 enrollment for Qbv") it is possible to enable taprio offload with a basetime of 0. However, the check if taprio offload is already enabled (and thus -EALREADY should be returned for igc_save_qbv_schedule) still relied on adapter->base_time > 0. This ca...

Problem Details: Only set adapter->taprio_offload_enable after validating the arguments. Otherwise, it stays set even if the offload was not enabled. Since the subsequent code does not get executed in case of invalid arguments, it will not be read at first. However, by activating and then deactivating another offload (...
