Audiomix on i.MX8MP registers two gates that share the same enable count
but use the same bit to control the gate instead of two bits. By adding
the flag IMX_CLK_GATE2_SINGLE_BIT we allow the gate2 to use the generic
gate ops for enable, disable and is_enabled.
For the disable_unused, nothing happens if this flag is specified.

This is first part of series which tries to return some sanity to

Extra goal of such refactoring is to ensure that QP is allocated at the

This patch set teaches libbpf how to declare and initialize ARRAY_OF_MAPS and
HASH_OF_MAPS maps. See patch #3 for all the details.
Patch #1 refactors parsing BTF definition of map to re-use it cleanly for
inner map definition parsing.
Patch #2 refactors map creation and destruction logic for reuse. It also fixes
existing bug with not closing successfully created maps when bpf_object map
creation overall fails.
Patch #3 adds support for an extension of BTF-defined map syntax, as well as
parsing, recording, and use of relocations to allow declaratively initialize
outer maps with references to inner maps.
v1->v2:
- rename __inner to __array (Alexei).
====================
Signed-off-by: Alexei Starovoitov <ast@kernel.org>
As discussed at LPC 2019 ([0]), this patch brings (a quite belated) support
for declarative BTF-defined map-in-map support in libbpf. It allows to define
ARRAY_OF_MAPS and HASH_OF_MAPS BPF maps without any user-space initialization
code involved.
Additionally, it allows to initialize outer map's slots with references to
respective inner maps at load time, also completely declaratively.
Despite a weak type system of C, the way BTF-defined map-in-map definition
works, it's actually quite hard to accidentally initialize outer map with
incompatible inner maps. This being C, of course, it's still possible, but
even that would be caught at load time and error returned with helpful debug
log pointing exactly to the slot that failed to be initialized.
As an example, here's a rather advanced HASH_OF_MAPS declaration and
initialization example, filling slots #0 and #4 with two inner maps:
#include <bpf/bpf_helpers.h>
struct inner_map {
__uint(type, BPF_MAP_TYPE_ARRAY);
__uint(max_entries, 1);
__type(key, int);
__type(value, int);
} inner_map1 SEC(".maps"),
inner_map2 SEC(".maps");
struct outer_hash {
__uint(type, BPF_MAP_TYPE_HASH_OF_MAPS);
__uint(max_entries, 5);
__uint(key_size, sizeof(int));
__array(values, struct inner_map);
} outer_hash SEC(".maps") = {
.values = {
[0] = &inner_map2,
[4] = &inner_map1,
},
};
Here's the relevant part of libbpf debug log showing pretty clearly of what's
going on with map-in-map initialization:
libbpf: .maps relo #0: for 6 value 0 rel.r_offset 96 name 260 ('inner_map1')
libbpf: .maps relo #0: map 'outer_arr' slot [0] points to map 'inner_map1'
libbpf: .maps relo #1: for 7 value 32 rel.r_offset 112 name 249 ('inner_map2')
libbpf: .maps relo #1: map 'outer_arr' slot [2] points to map 'inner_map2'
libbpf: .maps relo #2: for 7 value 32 rel.r_offset 144 name 249 ('inner_map2')
libbpf: .maps relo #2: map 'outer_hash' slot [0] points to map 'inner_map2'
libbpf: .maps relo #3: for 6 value 0 rel.r_offset 176 name 260 ('inner_map1')
libbpf: .maps relo #3: map 'outer_hash' slot [4] points to map 'inner_map1'
libbpf: map 'inner_map1': created successfully, fd=4
libbpf: map 'inner_map2': created successfully, fd=5
libbpf: map 'outer_hash': created successfully, fd=7
libbpf: map 'outer_hash': slot [0] set to map 'inner_map2' fd=5
libbpf: map 'outer_hash': slot [4] set to map 'inner_map1' fd=4
Notice from the log above that fd=6 (not logged explicitly) is used for inner
"prototype" map, necessary for creation of outer map. It is destroyed
immediately after outer map is created.
See also included selftest with some extra comments explaining extra details
of usage. Additionally, similar initialization syntax and libbpf functionality
can be used to do initialization of BPF_PROG_ARRAY with references to BPF
sub-programs. This can be done in follow up patches, if there will be a demand
for this.

====================
This patch series adds various observability APIs to bpf_link:
- each bpf_link now gets ID, similar to bpf_map and bpf_prog, by which
user-space can iterate over all existing bpf_links and create limited FD
from ID;
- allows to get extra object information with bpf_link general and
type-specific information;
- implements `bpf link show` command which lists all active bpf_links in the
system;
- implements `bpf link pin` allowing to pin bpf_link by ID or from other
pinned path.
v2->v3:
- improve spin locking around bpf_link ID (Alexei);
- simplify bpf_link_info handling and fix compilation error on sh arch;
v1->v2:
- simplified `bpftool link show` implementation (Quentin);
- fixed formatting of bpftool-link.rst (Quentin);
- fixed attach type printing logic (Quentin);
rfc->v1:
- dropped read-only bpf_links (Alexei);
- fixed bug in bpf_link_cleanup() not removing ID;
- fixed bpftool link pinning search logic;
- added bash-completion and man page.

Add support to look up bpf_link by ID and iterate over all existing bpf_links
in the system. GET_FD_BY_ID code handles not-yet-ready bpf_link by checking
that its ID hasn't been set to non-zero value yet. Setting bpf_link's ID is
done as the very last step in finalizing bpf_link, together with installing
FD. This approach allows users of bpf_link in kernel code to not worry about

Generate ID for each bpf_link using IDR, similarly to bpf_map and bpf_prog.
bpf_link creation, initialization, attachment, and exposing to user-space

through bpf_link_primer and bpf_link_prime(), bpf_link_settle(), and
bpf_link_cleanup() internal API. They guarantee that until bpf_link is
properly attached, user-space won't be able to access partially-initialized
bpf_link either from FD or ID. All this allows to simplify bpf_link attachment

Replace has_group_leader_pid with thread_group_leader. Years ago Oleg
suggested changing thread_group_leader to has_group_leader_pid to handle

Especially as then the code really did need to be the
thread_group_leader.
Today it doesn't make a difference if thread_group_leader races with
de_thread as the task returned from lookup_task in the non-thread case is
just used to find values in task->signal.
Since the races with de_thread have never been handled revert
has_group_header_pid to thread_group_leader for clarity.
Update the comment in lookup_task to remove implementation details that
are no longer true and to mention task->signal instead of task->sighand,
as the relevant cpu timer details are all in task->signal.
