Post FEAT_LPA2, Aarch64 extends the 4KB and 16KB translation granule to
large virtual addresses. Currently, the test is being skipped for said
granule sizes, because the page sizes have been statically defined; to
work around that would mean breaking the nice array of structs used for

If/when my SNC patches go upstream the SNC check could become:
snc_ways=$(ls -d /sys/fs/resctrl/mon_data/mon_L3_00/mon_sub_L3_* 2>/dev/null |
wc -l)
assuming you have /sys/fs/resctrl mounted.

There are multiple assertion formatting functions in the `assert.c`
file, which are not covered with tests yet. Implement the KUnit test
for these functions.
The test consists of 11 test cases for the following functions:
1) 'is_literal'
2) 'is_str_literal'
3) 'kunit_assert_prologue', test case

Resctrl selftest prints a message on test failure that Sub-Numa
Clustering (SNC) could be enabled and points the user to check theirs BIOS
settings. No actual check is performed before printing that message so
it is not very accurate in pinpointing a problem.
Figuring out if SNC is enabled is
Sub-NUMA Cluster divides CPUs sharing an L3 cache into separate NUMA
nodes. Systems may support splitting into either two or four nodes.
When SNC mode is enabled the effective amount of L3 cache available
for allocation is divided by the number of nodes per L3.
Detect which SNC mode is active by
Changes v2:
- Removed patches 2 and 3 since now this part will be supported by the
kernel.
Sub-Numa Clustering (SNC) allows splitting CPU cores, caches and memory
into multiple NUMA nodes. When enabled, NUMA-aware applications can
achieve better performance on bigger server platforms.

Merge dependency:
Reset nr_hugepages to zero before the start of the test.
If a non-zero number of hugepages is already set before the start of the
test, the following problems arise:
- The probability of the test getting OOM-killed increases.
Proof: The test wants to run on 80% of available memory to prevent
The compaction_test memory selftest introduces fragmentation in memory
and then tries to allocate as many hugepages as possible. This series
addresses some problems.
First off, correctly set the number of hugepages to zero before trying
to set a large number of them.
Now, consider a situation in
