Subject: [Linux-kernel-mentees] [PATCH v1 00/15] scsi: use generic power management
Date: Fri, 17 Jul 2020 12:04:23 +0530	[thread overview]
Message-ID: <20200717063438.175022-1-vaibhavgupta40@gmail.com> (raw)

Linux Kernel Mentee: Remove Legacy Power Management.

The purpose of this patch series is to upgrade power management in scsi
drivers. This has been done by upgrading .suspend() and .resume() callbacks.

The upgrade makes sure that the involvement of PCI Core does not change the
order of operations executed in a driver. Thus, does not change its behavior.

In general, drivers with legacy PM, .suspend() and .resume() make use of PCI
helper functions like pci_request/release_regions(), pci_set_power_state(),
pci_save/restore_state(), pci_enable/disable_device(), etc. to complete
their job.

The conversion requires the removal of those function calls, change the
callbacks' definition accordingly and make use of dev_pm_ops structure.

All patches are compile-tested only.
