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.
