Hi,
This series fixes up an issue that WB is not re-enabled after device reset.
Stanley Chu (2):
scsi: ufs: Re-enable WriteBooster after device reset
scsi: ufs: Uninline ufshcd_vops_device_reset function

Thus we need to reset those flag variables kept in struct hba to align the device status and ensure WriteBooster related functions being configured properly after device reset. Without this fix, WriteBooster will not be enabled successfully after by ufshcd_wb_ctrl() after device reset because hba->wb_enabled remains true. Flags required to be reset to default values: - fWriteBoosterEn: hba->wb_enabled - fWriteBoosterBufferFlushEn: hba->wb_buf_flush_enabled - fWriteBoosterBufferFlushDuringHibernate: No variable mapped Fixes: 3d17b9b5ab11 ("scsi: ufs: Add write booster feature support") Signed-off-by: Stanley Chu <stanley.chu@mediatek.com> --- drivers/scsi/ufs/ufshcd.h | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/drivers/scsi/ufs/ufshcd.h b/drivers/scsi/ufs/ufshcd.h index 08c8a591e6b0..36d367eb8139 100644 --- a/drivers/scsi/ufs/ufshcd.h +++ b/drivers/scsi/ufs/ufshcd.h @@ -1221,8 +1221,13 @@ static inline void ufshcd_vops_device_reset(struct ufs_hba *hba) if (hba->vops && hba->vops->device_reset) { int err = hba->vops->device_reset(hba); - if (!err) + if (!err) { ufshcd_set_ufs_dev_active(hba); + if (ufshcd_is_wb_allowed(hba)) { + hba->wb_enabled = false; + hba->wb_buf_flush_enabled = false; + } + } if (err != -EOPNOTSUPP) ufshcd_update_evt_hist(hba, UFS_EVT_DEV_RESET, err); } -- 2.18.0 ^ permalink raw reply related [flat|nested] 9+ messages in thread

Hi Bean, Thanks for your review. Yes, I agreed that wb related variables is a mess currently. I would like to clean them up once I have time.
