[dpdk-dev] [PATCH v4 1/5] test: load drivers when required

[David Marchand]

Concatenating to test_args if event_eth_tx_adapter_autotest is executed
makes all subsequent tests inherit from the drivers loading while this
is unneeded.

[dpdk-dev] [PATCH v4 2/5] test: skip subtests in no-huge mode

[David Marchand]

From: Ruifeng Wang <ruifeng.wang@arm.com>

When running with '--no-huge' flag, tests failed with messages as:
    ACL context creation with invalid NUMA should have failed!
    fbk hash creation should have failed
    test_table_pipeline: Check pipeline invalid params failed.

These cases test against invalid socket ID as input parameter, and
expect error return. But function calls return success because
invalid sock ID is overwritten to SOCKET_ID_ANY when in no-huge mode.

The tests against invalid socket ID are skipped in no-huge mode.

Fixes: 5640171c528a ("malloc: fix external heap allocation in no-huge mode")

[dpdk-dev] [PATCH v4 3/5] test: allow no-huge mode for fast-tests

[David Marchand]

From: Ruifeng Wang <ruifeng.wang@arm.com>

In environments where hugepage are not available, such as
containers, many cases in fast-tests suite should also run
if no-huge EAL option is used.

Flag is appended to each case in fast-tests suite to indicate
whether it lives with no-huge mode.
With the flag, fast-tests suite can be generated based on
detected hugepage availability of building environment.
All cases will be valid if hugepage is available, whereas
only applicable cases will be added if environment has no
hugepage support.

[dpdk-dev] [PATCH v4 4/5] ci: run tests even without hugepage

[David Marchand]

From: Ruifeng Wang <ruifeng.wang@arm.com>

As fast-tests suite generated with only applicable cases included,
hugepage is not a mandatory to run the test.
Ignore the result of hugepage set up, so that validation in environment
without hugepage can proceed.
