PCI helper functions such as pci_enable/disable_device(), pci_save/restore_state(), pci_set_power_state(), etc. were used by the legacy framework to perform standard operations related to PCI PM. This driver is using the generic framework and thus calls for those functions should be dropped as those tasks are now performed by the PCI core.

Provide HS-G4 support in MediaTek UFS platforms. To support HS-G4, introduce mechanism to get the MediaTek UFS controller version. With such information, driver can make right decision to apply different configurations in different controllers.

Some vendors need newer UniPro version to decide if some features can be enabled or not. Simply add missing enums for the latest UniPro versions. Link: https://lore.kernel.org/r/20201029115750.24391-6-stanley.chu@mediatek.comSigned-off-by:

UFS proprietary features (including features introduced later) in MediaTek UFS platforms have complicated combinations among different platforms. To ease code readability and maintenance, decouple all proprietary features from platform bindings. Each feature would be enabled only if specific property string is defined in device tree node.

In ufs_mtk_unipro_set_lpm(), use specific unsigned values as the argument to invoke ufshcd_dme_set(). At the same time, change the name of ufs_mtk_unipro_set_pm() to ufs_mtk_unipro_set_lpm() to align the naming convention in MediaTek UFS driver.

Whenever we encounter a sense code of ALUA transitioning in scsi_io_completion() it means that the SCSI midlayer ran out of retries trying to wait for ALUA transitioning. In these cases we should be passing up the error, but signalling that the I/O might be retried, preferably on another path. So return BLK_STS_AGAIN in these cases.

We should be setting the 'transitioning' ALUA state once we get a Unit Attention indicating the array is in transitioning. There are arrays which cannot respond to an RTPG while in transitioning, and others have issues correctly reporting the state. So better to set the state during Unit Attention handling and wait for TUR / RTPG to run its course. Link: https://lore.kernel.org/r/20200930080256.90964-4-hare@suse.deReviewed-by:

Hannes Reinecke authored
When the ALUA state indicates transitioning we should not retry the command immediately, but rather complete the command with BLK_STS_AGAIN to signal the completion handler that it might be retried. This allows multipathing to redirect the command to another path if possible, and avoid stalls during lengthy transitioning times.

Bodo knows the code better than me now, has time to review patches and is excellent at it, and has lots of ideas for how to make the driver better, so this patch adds him as the maintainer. There was no entry in there already. Andy had posted on the list here: https://www.spinics.net/lists/target-devel/msg14690.html when it got transitioned to me. I added an entry because several companies used it and I thought it would be easy for them to find Bodo.

It is simpler for drivers to provide a ->device_reset() callback irrespective of whether the GPIO, or firmware interface necessary to do the reset, is discovered during probe. Change ->device_reset() to return an error code. Drivers that provide the callback, but do not do the reset operation should return -EOPNOTSUPP.

DeepSleep is a UFS v3.1 feature that achieves the lowest power consumption of the device, apart from power off. In DeepSleep mode, no commands are accepted, and the only way to exit is using a hardware reset or power cycle. This patch assumes that if a power cycle was an option, then power off would be preferable, so only exit via a hardware reset is supported. Drivers that wish to support DeepSleep need to set a new capability flag UFSHCD_CAP_DEEPSLEEP and provide a hardware reset via the existing ->device_reset() callback. It is assumed that UFS devices with wspecversion >= 0x310 support DeepSleep.

A use-after-free or null-pointer error occurs when the 251-byte response data is copied from IOMB buffer to response message buffer in function pm8001_mpi_get_nvmd_resp(). After sending the command get_nvmd_data(), the caller begins to sleep by calling wait_for_complete() and waits for the wake-up from calling complete() in pm8001_mpi_get_nvmd_resp(). Due to unexpected events (e.g., interrupt), if response buffer gets freed before memcpy(), a use-after-free error will occur. To fix this, the complete() should be called after memcpy().

In function check_fw_ready() we busy wait using udelay. The CPU is not released and we see need_resched failures. Busy waiting is not necessary since we are in process context and we can sleep instead. Replace udelay with msleep of 20 ms intervals while waiting for firmware to become ready. It has been verified that check_fw_ready is not being used in interrupt context anywhere, hence it is safe to make this change.

Incorrect value of the running_req was causing the driver unload to be stuck during the SAS lldd_dev_gone notification handling. During SATA I/O completion, for some error status values, the driver schedules the event handler and running_req is decremented from that. However, there are some other error status values (like IO_DS_IN_RECOVERY, IO_XFER_ERR_LAST_PIO_DATAIN_CRC_ERR) where the I/O has already been completed by fw/driver so running_req is not decremented. Also during NCQ error handling, driver itself will initiate READ_LOG_EXT and ABORT_ALL. When libsas/libata initiate READ_LOG_EXT (0x2F), driver increments running_req. This will be completed by the driver in pm80xx_chip_sata_req(), but running_req was not decremented. Link: https://lore.kernel.org/r/20201102165528.26510-3-Viswas.G@microchip.com.comAcked-by:

Driver submits all internal requests (like abort_task, event acknowledgment etc.) through inbound queue 0. While submitting those, driver does not acquire any lock and this may lead to a race when there is an I/O request coming in on CPU0 and submitted through inbound queue 0. To avoid this, lock acquisition has been moved to pm8001_mpi_build_cmd(). All command submission will go through this path.
