HW access power manager common APIs
| void kbase_hwaccess_pm_gpu_active | ( | struct kbase_device * | kbdev | ) |
Perform any required actions for activating the GPU. Called when the first context goes active.
| kbdev | The kbase device structure for the device (must be a valid pointer) |
| void kbase_hwaccess_pm_gpu_idle | ( | struct kbase_device * | kbdev | ) |
Perform any required actions for idling the GPU. Called when the last context goes idle.
| kbdev | The kbase device structure for the device (must be a valid pointer) |
| void kbase_hwaccess_pm_halt | ( | struct kbase_device * | kbdev | ) |
Halt the power management framework.
Should ensure that no new interrupts are generated, but allow any currently running interrupt handlers to complete successfully. The GPU is forced off by the time this function returns, regardless of whether or not the active power policy asks for the GPU to be powered off.
| kbdev | The kbase device structure for the device (must be a valid pointer) |
| int kbase_hwaccess_pm_init | ( | struct kbase_device * | kbdev | ) |
Initialize the power management framework.
Must be called before any other power management function
| kbdev | The kbase device structure for the device (must be a valid pointer) |
| int kbase_hwaccess_pm_powerup | ( | struct kbase_device * | kbdev, |
| unsigned int | flags | ||
| ) |
kbase_hwaccess_pm_powerup - Power up the GPU. : The kbase device structure for the device (must be a valid pointer) : Flags to pass on to kbase_pm_init_hw
Power up GPU after all modules have been initialized and interrupt handlers installed.
Return: 0 if powerup was successful.
| void kbase_hwaccess_pm_resume | ( | struct kbase_device * | kbdev | ) |
Perform any backend-specific actions to resume the GPU from a suspend
| kbdev | The kbase device structure for the device (must be a valid pointer) |
| void kbase_hwaccess_pm_suspend | ( | struct kbase_device * | kbdev | ) |
Perform any backend-specific actions to suspend the GPU
| kbdev | The kbase device structure for the device (must be a valid pointer) |
| void kbase_hwaccess_pm_term | ( | struct kbase_device * | kbdev | ) |
Terminate the power management framework.
No power management functions may be called after this (except kbase_pm_init)
| kbdev | The kbase device structure for the device (must be a valid pointer) |
| const struct kbase_pm_ca_policy* kbase_pm_ca_get_policy | ( | struct kbase_device * | kbdev | ) |
Get the current policy.
Returns the policy that is currently active.
| kbdev | The kbase device structure for the device (must be a valid pointer) |
| int kbase_pm_ca_list_policies | ( | const struct kbase_pm_ca_policy *const ** | policies | ) |
Retrieve a static list of the available policies.
| [out] | policies | An array pointer to take the list of policies. This may be NULL. The contents of this array must not be modified. |
| void kbase_pm_ca_set_policy | ( | struct kbase_device * | kbdev, |
| const struct kbase_pm_ca_policy * | policy | ||
| ) |
Change the policy to the one specified.
| kbdev | The kbase device structure for the device (must be a valid pointer) |
| policy | The policy to change to (valid pointer returned from kbase_pm_ca_list_policies) |
| const struct kbase_pm_policy* kbase_pm_get_policy | ( | struct kbase_device * | kbdev | ) |
Get the current policy.
Returns the policy that is currently active.
| kbdev | The kbase device structure for the device (must be a valid pointer) |
| int kbase_pm_list_policies | ( | const struct kbase_pm_policy *const ** | policies | ) |
Retrieve a static list of the available policies.
| [out] | policies | An array pointer to take the list of policies. This may be NULL. The contents of this array must not be modified. |
| void kbase_pm_set_debug_core_mask | ( | struct kbase_device * | kbdev, |
| u64 | new_core_mask_js0, | ||
| u64 | new_core_mask_js1, | ||
| u64 | new_core_mask_js2 | ||
| ) |
Set the debug core mask.
This determines which cores the power manager is allowed to use.
| kbdev | The kbase device structure for the device (must be a valid pointer) |
| new_core_mask_js0 | The core mask to use for job slot 0 |
| new_core_mask_js0 | The core mask to use for job slot 1 |
| new_core_mask_js0 | The core mask to use for job slot 2 |
| void kbase_pm_set_policy | ( | struct kbase_device * | kbdev, |
| const struct kbase_pm_policy * | policy | ||
| ) |
Change the policy to the one specified.
| kbdev | The kbase device structure for the device (must be a valid pointer) |
| policy | The policy to change to (valid pointer returned from kbase_pm_list_policies) |
