Overview
|
||||
========
|
||||
|
||||
The folio_queue struct forms a single segment in a segmented list of folios
|
||||
that can be used to form an I/O buffer. As such, the list can be iterated over
|
||||
using the ITER_FOLIOQ iov_iter type.
|
||||
|
||||
The publicly accessible members of the structure are::
|
||||
|
||||
struct folio_queue {
|
||||
struct folio_queue *next;
|
||||
struct folio_queue *prev;
|
||||
...
|
||||
};
|
||||
|
||||
A pair of pointers are provided, ``next`` and ``prev``, that point to the
|
||||
segments on either side of the segment being accessed. Whilst this is a
|
||||
doubly-linked list, it is intentionally not a circular list; the outward
|
||||
sibling pointers in terminal segments should be NULL.
|
||||
|
||||
Each segment in the list also stores:
|
||||
|
||||
* an ordered sequence of folio pointers,
|
||||
* the size of each folio and
|
||||
* three 1-bit marks per folio,
|
||||
|
||||
but hese should not be accessed directly as the underlying data structure may
|
||||
change, but rather the access functions outlined below should be used.
|
||||
|
||||
The facility can be made accessible by::
|
||||
|
||||
#include <linux/folio_queue.h>
|
||||
|
||||
and to use the iterator::
|
||||
|
||||
#include <linux/uio.h>
|
||||
|
||||
|
||||
Initialisation
|
||||
==============
|
||||
|
||||
A segment should be initialised by calling::
|
||||
|
||||
void folioq_init(struct folio_queue *folioq);
|
||||
|
||||
with a pointer to the segment to be initialised. Note that this will not
|
||||
necessarily initialise all the folio pointers, so care must be taken to check
|
||||
the number of folios added.
|
||||
|
||||
|
||||
Adding and removing folios
|
||||
==========================
|
||||
|
||||
Folios can be set in the next unused slot in a segment struct by calling one
|
||||
of::
|
||||
|
||||
unsigned int folioq_append(struct folio_queue *folioq,
|
||||
struct folio *folio);
|
||||
|
||||
unsigned int folioq_append_mark(struct folio_queue *folioq,
|
||||
struct folio *folio);
|
||||
|
||||
Both functions update the stored folio count, store the folio and note its
|
||||
size. The second function also sets the first mark for the folio added. Both
|
||||
functions return the number of the slot used. [!] Note that no attempt is made
|
||||
to check that the capacity wasn't overrun and the list will not be extended
|
||||
automatically.
|
||||
|
||||
A folio can be excised by calling::
|
||||
|
||||
void folioq_clear(struct folio_queue *folioq, unsigned int slot);
|
||||
|
||||
This clears the slot in the array and also clears all the marks for that folio,
|
||||
but doesn't change the folio count - so future accesses of that slot must check
|
||||
if the slot is occupied.
|
||||
|
||||
|
||||
Querying information about a folio
|
||||
==================================
|
||||
|
||||
Information about the folio in a particular slot may be queried by the
|
||||
following function::
|
||||
|
||||
struct folio *folioq_folio(const struct folio_queue *folioq,
|
||||
unsigned int slot);
|
||||
|
||||
If a folio has not yet been set in that slot, this may yield an undefined
|
||||
pointer. The size of the folio in a slot may be queried with either of::
|
||||
|
||||
unsigned int folioq_folio_order(const struct folio_queue *folioq,
|
||||
unsigned int slot);
|
||||
|
||||
size_t folioq_folio_size(const struct folio_queue *folioq,
|
||||
unsigned int slot);
|
||||

The first function returns the size as an order and the second as a number of
|
||||
bytes.

||||
Querying information about a folio_queue
|
||||
========================================
|
||||
|
||||
Information may be retrieved about a particular segment with the following
|
||||
functions::
|
||||
|
||||
unsigned int folioq_nr_slots(const struct folio_queue *folioq);
|
||||
|
||||
unsigned int folioq_count(struct folio_queue *folioq);
|
||||
|
||||
bool folioq_full(struct folio_queue *folioq);
|
||||
|
||||
The first function returns the maximum capacity of a segment. It must not be
|
||||
assumed that this won't vary between segments. The second returns the number
|
||||
of folios added to a segments and the third is a shorthand to indicate if the
|
||||
segment has been filled to capacity.
|
||||
|
||||
Not that the count and fullness are not affected by clearing folios from the
|
||||
segment. These are more about indicating how many slots in the array have been
|
||||
initialised, and it assumed that slots won't get reused, but rather the segment
|
||||
will get discarded as the queue is consumed.
|
||||
|
||||
|
||||
Folio marks
|
||||
===========
|
||||
|
||||
Folios within a queue can also have marks assigned to them. These marks can be
|
||||
used to note information such as if a folio needs folio_put() calling upon it.
|
||||
There are three marks available to be set for each folio.
|
||||
|
||||
The marks can be set by::
|
||||
|
||||
void folioq_mark(struct folio_queue *folioq, unsigned int slot);
|
||||
void folioq_mark2(struct folio_queue *folioq, unsigned int slot);
|
||||
void folioq_mark3(struct folio_queue *folioq, unsigned int slot);
|
||||
|
||||
Cleared by::
|
||||
|
||||
void folioq_unmark(struct folio_queue *folioq, unsigned int slot);
|
||||
void folioq_unmark2(struct folio_queue *folioq, unsigned int slot);
|
||||
void folioq_unmark3(struct folio_queue *folioq, unsigned int slot);
|
||||
|
||||
And the marks can be queried by::
|
||||
|
||||
bool folioq_is_marked(const struct folio_queue *folioq, unsigned int slot);
|
||||
bool folioq_is_marked2(const struct folio_queue *folioq, unsigned int slot);
|
||||
bool folioq_is_marked3(const struct folio_queue *folioq, unsigned int slot);
|
||||
|
||||
The marks can be used for any purpose and are not interpreted by this API.
|
||||
|
||||
|
||||
Folio queue iteration
|
||||
=====================
|
||||
|
||||
A list of segments may be iterated over using the I/O iterator facility using
|
||||
an ``iov_iter`` iterator of ``ITER_FOLIOQ`` type. The iterator may be
|
||||
initialised with::
|
||||
|
||||
void iov_iter_folio_queue(struct iov_iter *i, unsigned int direction,
|
||||
const struct folio_queue *folioq,
|
||||
unsigned int first_slot, unsigned int offset,
|
||||
size_t count);
|
||||
|
||||
This may be told to start at a particular segment, slot and offset within a
|
||||
queue. The iov iterator functions will follow the next pointers when advancing
|
||||
and prev pointers when reverting when needed.
|
||||
|
||||
|
||||
Lockless simultaneous production/consumption issues
|
||||
===================================================
|
||||
|
||||
If properly managed, the list can be extended by the producer at the head end
|
||||
and shortened by the consumer at the tail end simultaneously without the need
|
||||
to take locks. The ITER_FOLIOQ iterator inserts appropriate barriers to aid
|
||||
with this.
|
||||
|
||||
Care must be taken when simultaneously producing and consuming a list. If the
|
||||
last segment is reached and the folios it refers to are entirely consumed by
|
||||
the IOV iterators, an iov_iter struct will be left pointing to the last segment
|
||||
with a slot number equal to the capacity of that segment. The iterator will
|
||||
try to continue on from this if there's another segment available when it is
|
||||
used again, but care must be taken lest the segment got removed and freed by
|
||||
the consumer before the iterator was advanced.
|
||||
|
||||
It is recommended that the queue always contain at least one segment, even if
|
||||
that segment has never been filled or is entirely spent. This prevents the
|
||||
head and tail pointers from collapsing.

||||

=====

Pkeys use 3 bits in each page table entry, to encode a "protection key index",
|

giving 8 possible keys.
|
||||
|
||||
Protections for each key are defined with a per-CPU user-writable system

register (POR_EL0). This is a 64-bit register encoding read, write and execute
|
||||
overlay permissions for each protection key index.
|

Being a CPU register, POR_EL0 is inherently thread-local, potentially giving
|
||||
each thread a different set of protections from every other thread.

Unlike x86_64, the protection key permissions also apply to instruction

community review. After positive community review, work should be sent to

|
||||
platform-specific maintainers, who are going to be responsible for handling
|
||||
patches for the platform from now on.
|
||||
|
||||
Note that the soc@kernel.org is usually not the place to discuss the patches,
