<div class="bz_comment_block">
<pre class="bz_comment_text">On 11/13/24 Tech board discussed the idea of tracking hugepage memory usage for
EAL bringup and basic DPDK workloads for per patch CI testing. Ideally UNH
could track a baseline for each DPDK tree, and then for per patch testing
compare the baseline for the tree a patch is applied on with the memory usage
test result for that patch.
Testcases would be:
1. Start testpmd (EAL starts) and check memory usage.
2. Start some basic l2/l3 forwarding and check memory usage during.
3. (possible) Create flow rules for a device, check memory usage.
4. etc.
Prereqs to adding this test:
1. Add a runtime command to testpmd which will return hugepage memory usage.
Other notes:
1. UNH would need to track tree memory usage for each device/driver, as we can
expect usage will not be consistent across devices. In principle it is similar
to how UNH stores performance baselines for NIC/tree combinations right now, so
no DB schema updates should be required.
