Consolidate the two separate timestamp Kconfig options into a single CONFIG_NET_TIMESTAMP option that covers SO_TIMESTAMP, SO_TIMESTAMPNS and SO_TIMESTAMPING socket options. Previously CONFIG_NET_TIMESTAMPING was a separate option only used by PKT sockets for hardware TX/RX timestamps and error queue support. Since both options guard the same io_time field in iob_s and share the s_options bitmask, merging them simplifies configuration without functional impact. Changes: - Replace all CONFIG_NET_TIMESTAMPING with CONFIG_NET_TIMESTAMP in pkt_input.c, pkt_recvmsg.c, pkt_sendmsg_buffered.c, pkt_sendmsg_unbuffered.c, pkt_sockif.c, pkt_netpoll.c, pkt.h, setsockopt.c, getsockopt.c - Simplify iob.h conditional from OR of both to single option - Remove NET_TIMESTAMPING Kconfig entry, update NET_TIMESTAMP description to cover all three socket options Signed-off-by: wenquan1 <wenquan1@xiaomi.com>

|
|
int "Preallocated socket callbacks"
|
|
default 16 if !DEFAULT_SMALL
|
|
default 4 if DEFAULT_SMALL
|
|
---help---
|
|
Number of preallocated socket callbacks (all tasks).
|
|
|
|
This number of callbacks will be pre-allocated during system boot.
|
|
If dynamic callbacks allocation is enabled, more callbacks may be
|
|
allocated at a later time, as the system needs them. Else this
|
|
will be the maximum number of callbacks available to the system
|
|
at all times.
|
|
|
|
Set to 0 to disable (and rely only on dynamic allocations).
|
|
|
|
config NET_ALLOC_DEVIF_CALLBACKS
|
|
int "Dynamic socket callbacks allocation"
|
|
default 0
|
|
---help---
|
|
Dynamic memory allocations for socket callbacks.
|
|
|
|
When set to 0 all dynamic allocations are disabled.
|
|
|
|
When set to 1 a new callback will be allocated every time, and
|
|
it will be free'd when no longer needed.
|
|
|
|
Setting this to 2 or more will allocate the callbacks in batches
|
|
(with batch size equal to this config). When a callback is no
|
|
longer needed, it will be returned to the free callbacks pool,
|
|
and it will never be deallocated!
