::fidl::internal::NaturalThenable< ::fuchsia_media::ProfileProvider::RegisterHandlerWithCapacity> RegisterHandlerWithCapacity (::fidl::Request< ::fuchsia_media::ProfileProvider::RegisterHandlerWithCapacity> request)Register a thread as a media thread. This notifies the media subsystem that this thread
should have an elevated scheduling profile applied to it in order to meet audio or video
deadlines.
`name` is the name of a system scheduling role to apply to the thread given by
`thread_handle` -- different products may customize the underlying scheduling strategy based
on the requested role. `period` is the suggested interval to be scheduled at. `period` may
be zero if the thread has no preferred scheduling interval. `capacity` is the proportion of
the scheduling interval the thread needs to be running to achieve good performance or to
meet the scheduling deadline defined by `period`. `capacity` may be zero if the workload has
no firm runtime requirements. Note that `capacity` should be a good faith estimate based on
the worst case runtime the thread requires each period. Excessive capacity requests may
be rejected or result in scaling back the performance of other threads to fit resource
limits.
Capacity, max runtime, and period have the following relationship:
capacity = max runtime / period
Where:
0
<
= max runtime
<
= period and 0
<
= capacity
<
= 1
For heterogeneous systems, the capacity should be planned / measured against the highest
performance processor(s) in the system. The system will automatically adjust the effective
capacity to account for slower processors and operating points and will avoid processors and
operating points that are too slow to meet the requested scheduling parameters (provided
they are reasonable).
Returns the period and capacity (actually maximum runtime) that was applied, either of which
may be zero to indicate not applicable.
::fidl::internal::NaturalThenable< ::fuchsia_media::ProfileProvider::UnregisterHandler> UnregisterHandler (::fidl::Request< ::fuchsia_media::ProfileProvider::UnregisterHandler> request)Reset a thread's scheduling profile to the default.
::fidl::internal::NaturalThenable< ::fuchsia_media::ProfileProvider::RegisterMemoryRange> RegisterMemoryRange (::fidl::Request< ::fuchsia_media::ProfileProvider::RegisterMemoryRange> request)Register a memory range as being used for media processing. This notifies the media
subsystem that this memory should have an elevated memory profile applied to it in order to
meet audio or video deadlines.
`name` is the name of a system memory role to apply to the memory given by
`vmar_handle` -- different products may customize the underlying memory strategy based
on the requested role.
::fidl::internal::NaturalThenable< ::fuchsia_media::ProfileProvider::UnregisterMemoryRange> UnregisterMemoryRange (::fidl::Request< ::fuchsia_media::ProfileProvider::UnregisterMemoryRange> request)Reset a memory range's memory profile.
