Event ring priorities have remained out of use and are set to 1 by default. This series brings about an enum entry expanding use of the priority field by adding high priority tasklet scheduling to the menu. In some cases, tasklet scheduling delays can be a nuisance. An example would be ath11k adding a610f3c65d3b ("bus: mhi: Wait for M2 state during system resume") in response to it. This issue can be potentially avoided if the controller uses a dedicated event ring for control packets with high priority tasklet scheduling in place. There are no functional changes added to the controller (pci_generic or ath11k) drivers with this series and the only changes there are use of the enum in place of a harcoded value of "1". In the future, controllers can opt in to have any event ring scheduled in high priority. Tested on: X86_64 architecture with SDX65 on Ubuntu 18.04 distribution. v2: -Remove enum and update kernel doc for priority simplifying the implementation -Drop patches for controller changes as they become unnecessary -Merge adding and enabling of support patches Hemant Kumar (1): bus: mhi: core: Add support for processing priority of event ring drivers/bus/mhi/core/init.c | 3 +-- drivers/bus/mhi/core/main.c | 9 +++++++-- include/linux/mhi.h | 2 +- 3 files changed, 9 insertions(+), 5 deletions(-) -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, a Linux Foundation Collaborative Project
