Mutexes are represented by 'struct mutex', defined in include/linux/mutex.h
-and implemented in kernel/locking/mutex.c. These locks use a three
-state atomic counter (->count) to represent the different possible
-transitions that can occur during the lifetime of a lock:
-
- 1: unlocked
- 0: locked, no waiters
- negative: locked, with potential waiters
-
-In its most basic form it also includes a wait-queue and a spinlock
-that serializes access to it. CONFIG_SMP systems can also include
-a pointer to the lock task owner (->owner) as well as a spinner MCS
-lock (->osq), both described below in (ii).
+and implemented in kernel/locking/mutex.c. These locks use an atomic variable
+(->owner) to keep track of the lock state during its lifetime. Field owner
+actually contains 'struct task_struct *' to the current lock owner and it is
+therefore NULL if not currently owned. Since task_struct pointers are aligned
+at at least L1_CACHE_BYTES, low bits (3) are used to store extra state (e.g.,
+if waiter list is non-empty). In its most basic form it also includes a
+wait-queue and a spinlock that serializes access to it. Furthermore,
+CONFIG_MUTEX_SPIN_ON_OWNER=y systems use a spinner MCS lock (->osq), described
+below in (ii).
When acquiring a mutex, there are three possible paths that can be
taken, depending on the state of the lock:
-(i) fastpath: tries to atomically acquire the lock by decrementing the
- counter. If it was already taken by another task it goes to the next
- possible path. This logic is architecture specific. On x86-64, the
- locking fastpath is 2 instructions:
-
- 0000000000000e10 <mutex_lock>:
- e21: f0 ff 0b lock decl (%rbx)
- e24: 79 08 jns e2e <mutex_lock+0x1e>
-
- the unlocking fastpath is equally tight:
-
- 0000000000000bc0 <mutex_unlock>:
- bc8: f0 ff 07 lock incl (%rdi)
- bcb: 7f 0a jg bd7 <mutex_unlock+0x17>
-
+(i) fastpath: tries to atomically acquire the lock by cmpxchg()ing the owner with
+ the current task. This only works in the uncontended case (cmpxchg() checks
+ against 0UL, so all 3 state bits above have to be 0). If the lock is
+ contended it goes to the next possible path.
(ii) midpath: aka optimistic spinning, tries to spin for acquisition
while the lock owner is running and there are no other tasks ready
Disadvantages
-------------
-Unlike its original design and purpose, 'struct mutex' is larger than
-most locks in the kernel. E.g: on x86-64 it is 40 bytes, almost twice
-as large as 'struct semaphore' (24 bytes) and tied, along with rwsems,
-for the largest lock in the kernel. Larger structure sizes mean more
-CPU cache and memory footprint.

TCP Segmentation Offload
========================
fragmentation offload are the same as TSO. However the IPv4 ID for
fragments should not increment as a single IPv4 datagram is fragmented.
+UFO is deprecated: modern kernels will no longer generate UFO skbs, but can
+still receive them from tuntap and similar devices. Offload of UDP-based
+tunnel protocols is still supported.

========================================================
fact that the outer header also requests to have a non-zero checksum
included in the outer header.
-Finally there is SKB_GSO_REMCSUM which indicates that a given tunnel header
-has requested a remote checksum offload. In this case the inner headers
-will be left with a partial checksum and only the outer header checksum
-will be computed.
+Finally there is SKB_GSO_TUNNEL_REMCSUM which indicates that a given tunnel
+header has requested a remote checksum offload. In this case the inner
+headers will be left with a partial checksum and only the outer header
+checksum will be computed.
Generic Segmentation Offload
============================
is the outer IPv4 ID field. It is up to the device drivers to guarantee
that the IPv4 ID field is incremented in the case that a given header does
not have the DF bit set.
+
+SCTP accelleration with GSO
+===========================
+
+SCTP - despite the lack of hardware support - can still take advantage of
+GSO to pass one large packet through the network stack, rather than
+multiple small packets.
+
+This requires a different approach to other offloads, as SCTP packets
+cannot be just segmented to (P)MTU. Rather, the chunks must be contained in
+IP segments, padding respected. So unlike regular GSO, SCTP can't just
+generate a big skb, set gso_size to the fragmentation point and deliver it
+to IP layer.
+
+Instead, the SCTP protocol layer builds an skb with the segments correctly
+padded and stored as chained skbs, and skb_segment() splits based on those.
+To signal this, gso_size is set to the special value GSO_BY_FRAGS.
+
+Therefore, any code in the core networking stack must be aware of the
+possibility that gso_size will be GSO_BY_FRAGS and handle that case
+appropriately. (For size checks, the skb_gso_validate_*_len family of
+helpers do this automatically.)
+
+This also affects drivers with the NETIF_F_FRAGLIST & NETIF_F_GSO_SCTP bits
+set. Note also that NETIF_F_GSO_SCTP is included in NETIF_F_GSO_SOFTWARE.

+ * Rules for modifying this file:
+ * a) Update of this file should typically correspond to a datamanual revision.
+ * Datamanual revision that was used should be updated in comment below.
+ * If there is no update to datamanual, do not update the values. If you
+ * need to use values different from that recommended by the datamanual
+ * for your design, then you should consider adding values to the device-
+ * -tree file for your board directly.
+ * b) We keep the mode names as close to the datamanual as possible. So
+ * if the manual calls a mode, DDR50, or DDR or DDR 1.8v or DDR 3.3v,
+ * we follow that in code too.
+ * c) If the values change between multiple revisions of silicon, we add
+ * a revision tag to both the new and old entry. Use 'rev11' for PG 1.1,
+ * 'rev20' for PG 2.0 and so on.
+ * d) The node name and node label should be the exact same string. This is
+ * to curb naming creativity and achieve consistency.
