105 the upper bits in that field for a dma-pinned count. "Sort of", means that,
109 on it 1024 times, then it will appear to have a single dma-pinned count.

202 The whole point of marking folios as "DMA-pinned" or "gup-pinned" is to be able
203 to query, "is this folio DMA-pinned?" That allows code such as folio_mkclean()

/linux/Documentation/arch/powerpc/
A Dpmu-ebb.rst53 existing "pinned" and "exclusive" attributes of perf_events. This means EBB
54 events will be given priority over other events, unless they are also pinned.
55 If an EBB event and a regular event are both pinned, then whichever is enabled
70 An EBB event must be created with the "pinned" and "exclusive" attributes set.
100 This behaviour occurs because the EBB event is pinned and exclusive. When the
101 EBB event is enabled it will force all other non-pinned events off the PMU. In
103 pinned on the PMU then the enable will not be successful.
