scsi: ufs: Introduce skipping manual flush for Write Booster · 5df6f2de

由 Kiwoong Kim 提交于 8月 25, 2020

We have two knobs to control flush for write booster,
fWriteBoosterBufferFlushDuringHibernate and fWriteBoosterBufferFlushEn.

Some vendors use only fWriteBoosterBufferFlushDuringHibernate because this
can reportedly cover most scenarios. Also, there have been some reports
that flush by fWriteBoosterBufferFlushEn could lead to increased power
consumption thanks to unexpected internal operations. Consequently, we need
a way to enable or disable fWriteBoosterEn operations. Add quirk to bypass
manual flush.

The legacy API wrappers in include/linux/pci-dma-compat.h should go away as
they create unnecessary midlayering for include/linux/dma-mapping.h API.
Instead use dma-mapping.h API directly.

The patch has been generated with the coccinelle script below.  And has
been hand modified to replace each GFP_ with a correct flag depending upon
the context.  Compile tested.

scsi: mpt3sas: Remove pci-dma-compat wrapper API · a5a20c4a

由 Suraj Upadhyay 提交于 7月 29, 2020

The legacy API wrappers in include/linux/pci-dma-compat.h should go away as
they create unnecessary midlayering for include/linux/dma-mapping.h API.
Instead use dma-mapping.h API directly.

The patch has been generated with the coccinelle script below.  Compile
tested.
