Subject: [PATCH v1 00/16] Add Multi Circular Queue Support
Date: Thu, 22 Sep 2022 18:05:07 -0700 [thread overview]
Message-ID: <cover.1663894792.git.quic_asutoshd@quicinc.com> (raw)
UFS Multi-Circular Queue (MCQ) has been added in UFSHCI v4.0 to improve storage performance.
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.
v1:
- Split the changes
- Addressed Bart's comments
- Addressed Bean's comments
* RFC versions:
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)
