20 * -------------------
21 * Statistics Overview
22 * -------------------
23 *
24 * As part of managing the driver and understanding what's going on, we keep
25 * track of statistics from two different sources:
26 *
27 * - Statistics from the device
28 * - Statistics maintained by the driver
29 *
30 * Generally, the hardware provides us traditional IETF and MIB Ethernet
31 * statistics, for example, the total packets in and out, various errors in
32 * packets, the negotiated status etc. The driver, on the other hand, primarily
33 * contains statistics around driver-specific issues, such as information about
34 * checksumming on receive and transmit and the data in and out of a specific
35 * ring.
36 *
37 * We export statistics in two different forms. The first form is the required
38 * GLDv3 endpoints, specifically:
39 *
40 * - The general GLDv3 mc_getstat interface
41 * - The GLDv3 ring mri_stat interface
42 *
43 * The second form that we export statistics is through kstats. kstats are
44 * exported in different ways. Particularly we arrange the kstats to monitor the
45 * layout of the device. Currently we have kstats which capture both the IEEE
46 * and driver-implementation specific stats. There are kstats for each of the
47 * following structures:
48 *
49 * - Each physical function
50 * - Each VSI
51 * - Each Queue
52 *
53 * The PF's kstat is called 'pfstats' so as not to collide with other system
54 * provided kstats. Thus, for instance 0, usually the first PF, the full kstat
55 * would be: i40e:0:pfstats:.
56 *
57 * The kstat for each VSI is called vsi_%instance. So for the first PF, which is
58 * instance zero and the first vsi, which has id 0, it will be named vsi_0 and
59 * the full kstat would be i40e:0:vsi_0:.
60 *
61 * The kstat for each queue is trqpair_tx_%queue and trqpair_rx_%queue. Note
62 * that these are labeled based on their local index, which may mean that
63 * different instances have overlapping sets of queues. This isn't a problem as
64 * the kstats will always use the instance number of the pf to distinguish it in
65 * the kstat tuple.
66 *
67 * ---------------------
68 * Hardware Arrangements
69 * ---------------------
70 *
71 * The hardware keeps statistics at each physical function/MAC (PF) and it keeps
72 * statistics on each virtual station interface (VSI).
73 *
74 * The hardware keeps these statistics as 32-bit and 48-bit counters. We are
75 * required to read them and then compute the differences between them. The
76 * 48-bit counters span more than one 32-bit register in the BAR. The hardware
77 * suggests that to read them, we perform 64-bit reads of the lower of the two
78 * registers that make up a 48-bit stat. The hardware guarantees that the reads
79 * of those two registers will be atomic and we'll get a consistent value, not a
80 * property it has for every read of two registers.
81 *
82 * For every kstat we have based on this, we have a corresponding uint64_t that
83 * we keep around as a base value in a separate structure. Whenever we read a
84 * value, we end up grabbing the current value, calculating a difference between
85 * the previously stored value and the current one, and updating the kstat with
86 * that difference. After which, we go through and update the base value that we
87 * stored. This is all encapsulated in i40e_stat_get_uint32() and
88 * i40e_stat_get_uint48().
89 *
90 * The only unfortunate thing here is that the hardware doesn't give us any kind
91 * of overflow counter. It just tries to make sure that the uint32_t and
92 * uint48_t counters are large enough to hopefully not overflow right away. This
93 * isn't the most reassuring statement and we should investigate ways of
94 * ensuring that if a system is active, but not actively measured, we don't lose
95 * data.
96 *
97 * The pf kstats data is stored in the i40e_t`i40e_pf_kstat. It is backed by the
98 * i40e_t`i40e_pf_stat structure. Similarly the VSI related kstats are in
99 * i40e_t`i40e_vsis[idx].iv_kstats and the data is backed in the
100 * i40e_t`i40e_vsis[idx].iv_stats. All of this data is protected by the
101 * i40e_stat_lock, which should be taken last, when acquiring locks.
