This patch series is a RFC implementation of this. This is the initial driver implementation and it has been verified by booting on an emulation platform. During testing, all low power modes were disabled and it was in HS-G1 mode. Please take a look and let us know your thoughts. v2 -> v3: - Split the changes based on functionality - Addressed queue configuration issues - Faster SQE tail pointer increments - Addressed comments from Bart and Manivannan v1 -> v2: - Enabled host_tagset - Added queue num configuration support - Added one more vops to allow vendor provide the wanted MAC - Determine nutrs and can_queue by considering both MAC, bqueuedepth and EXT_IID support - Postponed MCQ initialization and scsi_add_host() to async probe - Used (EXT_IID, Task Tag) tuple to support up to 4096 tasks (theoretically) Asutosh Das (2): ufs: core: prepare ufs for multi circular queue support ufs: core: mcq: Adds Multi-Circular Queue support Can Guo (2): ufs: core: Add Event Specific Interrupt configuration vendor specific ops ufs: host: qcom: Add MCQ support drivers/ufs/core/Makefile | 2 +- drivers/ufs/core/ufs-mcq.c | 474 +++++++++++++++++++++++++++++++++++++++++ drivers/ufs/core/ufshcd-priv.h | 102 +++++++++ drivers/ufs/core/ufshcd.c | 370 +++++++++++++++++++++++++------- drivers/ufs/host/ufs-qcom.c | 134 ++++++++++++ drivers/ufs/host/ufs-qcom.h | 13 ++ include/ufs/ufs.h | 6 + include/ufs/ufshcd.h | 137 ++++++++++++ include/ufs/ufshci.h | 79 +++++++ 9 files changed, 1238 insertions(+), 79 deletions(-) create mode 100644 drivers/ufs/core/ufs-mcq.c
