+ * This function also assumes that struct drm_info_list.data will point to the

/**
* DOC: Xe Power Management
*
- * Xe PM shall be guided by the simplicity.
- * Use the simplest hook options whenever possible.
- * Let's not reinvent the runtime_pm references and hooks.
- * Shall have a clear separation of display and gt underneath this component.
+ * Xe PM implements the main routines for both system level suspend states and
+ * for the opportunistic runtime suspend states.
*
- * What's next:
+ * System Level Suspend (S-States) - In general this is OS initiated suspend
+ * driven by ACPI for achieving S0ix (a.k.a. S2idle, freeze), S3 (suspend to ram),
+ * S4 (disk). The main functions here are `xe_pm_suspend` and `xe_pm_resume`. They
+ * are the main point for the suspend to and resume from these states.
*
- * For now s2idle and s3 are only working in integrated devices. The next step
- * is to iterate through all VRAM's BO backing them up into the system memory
- * before allowing the system suspend.
+ * PCI Device Suspend (D-States) - This is the opportunistic PCIe device low power
+ * state D3, controlled by the PCI subsystem and ACPI with the help from the
+ * runtime_pm infrastructure.
+ * PCI D3 is special and can mean D3hot, where Vcc power is on for keeping memory
+ * alive and quicker low latency resume or D3Cold where Vcc power is off for
+ * better power savings.
+ * The Vcc control of PCI hierarchy can only be controlled at the PCI root port
+ * level, while the device driver can be behind multiple bridges/switches and
+ * paired with other devices. For this reason, the PCI subsystem cannot perform
+ * the transition towards D3Cold. The lowest runtime PM possible from the PCI
+ * subsystem is D3hot. Then, if all these paired devices in the same root port
+ * are in D3hot, ACPI will assist here and run its own methods (_PR3 and _OFF)
+ * to perform the transition from D3hot to D3cold. Xe may disallow this
+ * transition by calling pci_d3cold_disable(root_pdev) before going to runtime
+ * suspend. It will be based on runtime conditions such as VRAM usage for a
+ * quick and low latency resume for instance.
*
- * Also runtime_pm needs to be here from the beginning.
+ * Runtime PM - This infrastructure provided by the Linux kernel allows the
+ * device drivers to indicate when the can be runtime suspended, so the device
+ * could be put at D3 (if supported), or allow deeper package sleep states
+ * (PC-states), and/or other low level power states. Xe PM component provides
+ * `xe_pm_runtime_suspend` and `xe_pm_runtime_resume` functions that PCI
+ * subsystem will call before transition to/from runtime suspend.
*
- * RC6/RPS are also critical PM features. Let's start with GuCRC and GuC SLPC
- * and no wait boost. Frequency optimizations should come on a next stage.
+ * Also, Xe PM provides get and put functions that Xe driver will use to
+ * indicate activity. In order to avoid locking complications with the memory
+ * management, whenever possible, these get and put functions needs to be called
+ * from the higher/outer levels.
+ * The main cases that need to be protected from the outer levels are: IOCTL,
+ * sysfs, debugfs, dma-buf sharing, GPU execution.
+ *
+ * This component is not responsible for GT idleness (RC6) nor GT frequency
+ * management (RPS).
