This patch series introduces in the first change a new UFS ioctl, allowing user-space to send UFS queries and retrieve information from them. In addition, the other three patches add utilities to support debugging efforts and supply information that will help analysis of issue: UFS trace events, dump host controller registers and requests descriptors on failures, several statistics. Dolev Raviv (1): scsi: ufs: add ioctl interface for query request Gilad Broner (1): scsi: ufs: add trace events and dump prints for debug Lee Susman (1): scsi: ufs: add debugfs for ufs Sujit Reddy Thumma (1): scsi: ufs: inject errors to verify error handling drivers/scsi/ufs/Makefile | 1 + drivers/scsi/ufs/debugfs.c | 1038 +++++++++++++++++++++++++++++++++++++++++ drivers/scsi/ufs/debugfs.h | 42 ++ drivers/scsi/ufs/ufs-qcom.c | 53 +++ drivers/scsi/ufs/ufs.h | 53 +-- drivers/scsi/ufs/ufshcd.c | 964 ++++++++++++++++++++++++++++++++++++-- drivers/scsi/ufs/ufshcd.h | 115 +++++ drivers/scsi/ufs/ufshci.h | 3 + include/linux/ftrace_event.h | 3 + include/trace/events/ufs.h | 227 +++++++++ include/uapi/scsi/Kbuild | 1 + include/uapi/scsi/ufs/Kbuild | 3 + include/uapi/scsi/ufs/ioctl.h | 57 +++ include/uapi/scsi/ufs/ufs.h | 66 +++ lib/Kconfig.debug | 14 + 15 files changed, 2556 insertions(+), 84 deletions(-) create mode 100644 drivers/scsi/ufs/debugfs.c create mode 100644 drivers/scsi/ufs/debugfs.h create mode 100644 include/trace/events/ufs.h create mode 100644 include/uapi/scsi/ufs/Kbuild create mode 100644 include/uapi/scsi/ufs/ioctl.h create mode 100644 include/uapi/scsi/ufs/ufs.h -- 1.8.5.2 -- Qualcomm Israel, on behalf of Qualcomm Innovation Center, Inc.
