77 * Periodic OA samples are read() into these buffer structures via the
78 * i915 perf kernel interface and appended to the
79 * perf_ctx->sample_buffers linked list. When we process the
80 * results of an OA metrics query we need to consider all the periodic
81 * samples between the Begin and End MI_REPORT_PERF_COUNT command
84 * 'Periodic' is a simplification as there are other automatic reports
85 * written by the hardware also buffered here.
87 * Considering three queries, A, B and C:
90 * ________________A_________________
92 * | ________B_________ _____C___________
95 * And an illustration of sample buffers read over this time frame:
96 * [HEAD ][ ][ ][ ][ ][ ][ ][ ][TAIL ]
98 * These nodes may hold samples for query A:
99 * [ ][ ][ A ][ A ][ A ][ A ][ A ][ ][ ]
101 * These nodes may hold samples for query B:
102 * [ ][ ][ B ][ B ][ B ][ ][ ][ ][ ]
104 * These nodes may hold samples for query C:
105 * [ ][ ][ ][ ][ ][ C ][ C ][ C ][ ]
107 * The illustration assumes we have an even distribution of periodic
108 * samples so all nodes have the same size plotted against time:
110 * Note, to simplify code, the list is never empty.
112 * With overlapping queries we can see that periodic OA reports may
113 * relate to multiple queries and care needs to be take to keep
114 * track of sample buffers until there are no queries that might
115 * depend on their contents.
117 * We use a node ref counting system where a reference ensures that a
118 * node and all following nodes can't be freed/recycled until the
119 * reference drops to zero.
121 * E.g. with a ref of one here:
122 * [ 0 ][ 0 ][ 1 ][ 0 ][ 0 ][ 0 ][ 0 ][ 0 ][ 0 ]
124 * These nodes could be freed or recycled ("reaped"):
127 * These must be preserved until the leading ref drops to zero:
128 * [ 1 ][ 0 ][ 0 ][ 0 ][ 0 ][ 0 ][ 0 ]
130 * When a query starts we take a reference on the current tail of
131 * the list, knowing that no already-buffered samples can possibly
132 * relate to the newly-started query. A pointer to this node is
133 * also saved in the query object's ->oa.samples_head.
135 * E.g. starting query A while there are two nodes in .sample_buffers:
136 * ________________A________
140 * ^_______ Add a reference and store pointer to node in
143 * Moving forward to when the B query starts with no new buffer nodes:
144 * (for reference, i915 perf reads() are only done when queries finish)
145 * ________________A_______
150 * ^_______ Add a reference and store pointer to
151 * node in B->oa.samples_head
153 * Once a query is finished, after an OA query has become 'Ready',
154 * once the End OA report has landed and after we we have processed
155 * all the intermediate periodic samples then we drop the
156 * ->oa.samples_head reference we took at the start.
158 * So when the B query has finished we have:
159 * ________________A________
160 * | ______B___________
162 * [ 0 ][ 1 ][ 0 ][ 0 ][ 0 ]
163 * ^_______ Drop B->oa.samples_head reference
165 * We still can't free these due to the A->oa.samples_head ref:
166 * [ 1 ][ 0 ][ 0 ][ 0 ]
168 * When the A query finishes: (note there's a new ref for C's samples_head)
169 * ________________A_________________
173 * [ 0 ][ 0 ][ 0 ][ 0 ][ 1 ][ 0 ][ 0 ]
174 * ^_______ Drop A->oa.samples_head reference
176 * And we can now reap these nodes up to the C->oa.samples_head:
177 * [ X ][ X ][ X ][ X ]
178 * keeping -> [ 1 ][ 0 ][ 0 ]
180 * We reap old sample buffers each time we finish processing an OA
181 * query by iterating the sample_buffers list from the head until we
182 * find a referenced node and stop.
184 * Reaped buffers move to a perfquery.free_sample_buffers list and
185 * when we come to read() we first look to recycle a buffer from the
186 * free_sample_buffers list before allocating a new buffer.

1710 * drain everything currently running on the GPU until the hardware is idle
1711 * before capturing the first snapshot of counters - otherwise the results

1714 * When the command parser reaches an End marker it needs to stall until
1715 * everything currently running on the GPU has finished before capturing the
1716 * end snapshot - otherwise the results won't be a complete representation

1725 * workload is stretched by larger pipeline bubbles the bubbles themselves
