Change Details

This patch enables WriteBooster to improve write performance. It reserves SLC space from normal (TLC) storage to handle incoming writes, reducing latency and handling bursty writes. The buffer can be dedicated to a single LU or shared across multiple LUs, depending on configuration. Data staged in SLC is later flushed back to TLC automatically or on demand, without changing data placement. The following table shows WriteBooster performance as tested on a Galaxy Book S + UFS 4.0(HS-GEAR 4) device. ---------------------------------------------------------------- | Workload | BS | QD | WriteBooster | Bandwidth | ---------------------------------------------------------------- | Sequential Write | 1MB | 32 | On | 1568 MiB/s | | Sequential Write | 1MB | 32 | Off | 556 MiB/s | ---------------------------------------------------------------- Also, this function adds a power mode change quirk to the Intel Lakefield UFS controller.
