The ungate work turns on the clock before it exits hibern8, if the link was put in hibern8 during clock gating work. There occurs a race condition when clock scaling work calls ufshcd_hold() to make sure low power states cannot be entered, but that returns by checking only whether the clocks are on. This causes the clock scaling work to issue UIC commands when the link is in hibern8 causing failures. Make sure we exit hibern8 state before returning from ufshcd_hold(). Callstacks for race condition: ufshcd_scale_gear ufshcd_devfreq_scale ufshcd_devfreq_target update_devfreq devfreq_monitor process_one_work worker_thread kthread ret_from_fork ufshcd_uic_hibern8_exit ufshcd_ungate_work process_one_work worker_thread kthread ret_from_fork Signed-off-by:

In case the power configuration fails, skip further processing of the probing function and return immediately. This has 2 reasons: 1. Don't allow the UFS to continue running in PWM 2. Avoid multiple calls to pm_runtime_put_sync() when not in error handling or power management contexts Signed-off-by:

During runtime resume operation, clock scaling may get indirectly resumed via call to ufshcd_set_dev_pwr_mode(): Start/Stop Unit command times out and SCSI error handling ultimately calls the host reset handler to recover, during which clock scaling is resumed. Error case exit path of runtime resume will disable clocks. As clock scaling was already resumed, it will get scheduled later on and try to access UFS registers while clocks are disabled, resulting in unclocked register access. Signed-off-by:

Add a write memory barrier to make sure descriptors prepared are actually written to memory before ringing the doorbell. We have also added the write memory barrier after ringing the doorbell register so that controller sees the new request immediately. Signed-off-by:

This patch addresses the issue of driver firing DCMDs in PCI shutdown/detach path irrespective of firmware state. Driver will now check whether firmware is in operational state or not before firing DCMDs. If firmware is in unrecoverable state or does not become operational within specfied time, driver will skip firing DCMDs. [mkp: fixed typos] Signed-off-by:

For SRIOV enabled firmware, if there is a OCR(online controller reset) possibility driver set the convert flag to 1, which is not happening if there are outstanding commands even after 180 seconds. As driver does not set convert flag to 1 and still making the OCR to run, VF(Virtual function) driver is directly writing on to the register instead of waiting for 30 seconds. Setting convert flag to 1 will cause VF driver will wait for 30 secs before going for reset. CC: stable@vger.kernel.org Signed-off-by:
