[drm/mgag200] 90f479ae51: vm-scalability.median -18.8% regression
by kernel test robot
Greeting,
FYI, we noticed a -18.8% regression of vm-scalability.median due to commit:
commit: 90f479ae51afa45efab97afdde9b94b9660dd3e4 ("drm/mgag200: Replace struct mga_fbdev with generic framebuffer emulation")
https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next.git master
in testcase: vm-scalability
on test machine: 288 threads Intel(R) Xeon Phi(TM) CPU 7295 @ 1.50GHz with 80G memory
with following parameters:
runtime: 300s
size: 8T
test: anon-cow-seq-hugetlb
cpufreq_governor: performance
test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us.

883a2cefc0 ("rcu/tree: support kfree_bulk() interface in .."): [ 13.962148] WARNING: CPU: 0 PID: 212 at lib/debugobjects.c:484 debug_print_object
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://github.com/0day-ci/linux/commits/Uladzislau-Rezki-Sony/rcu-tree-s...
commit 883a2cefc0684ec945a069e1091407f1f07a0558
Author: Uladzislau Rezki (Sony) <urezki(a)gmail.com>
AuthorDate: Tue Dec 31 13:22:41 2019 +0100
Commit: 0day robot <lkp(a)intel.com>

rcu/tree: support kfree_bulk() interface in kfree_rcu()
kfree_rcu() logic can be improved further by using kfree_bulk()
interface along with "basic batching support" introduced earlier.
The are at least two advantages of using "bulk" interface:
- in case of large number of kfree_rcu() requests kfree_bulk()
reduces the per-object overhead caused by calling kfree()
per-object.
- reduces the number of cache-misses due to "pointer chasing"
between objects which can be far spread between each other.
This approach defines a new kfree_rcu_bulk_data structure that
stores pointers in an array with a specific size. Number of entries
in that array depends on PAGE_SIZE making kfree_rcu_bulk_data
structure to be exactly one page.
Since it deals with "block-chain" technique there is an extra
need in dynamic allocation when a new block is required. Memory
is allocated with GFP_NOWAIT | __GFP_NOWARN flags, i.e. that
allows to skip direct reclaim under low memory condition to
prevent stalling and fails silently under high memory pressure.
The "emergency path" gets maintained when a system is run out
of memory. In that case objects are linked into regular list
and that is it.
In order to evaluate it, the "rcuperf" was run to analyze how
much memory is consumed and what is kfree_bulk() throughput.
Testing on the HiKey-960, arm64, 8xCPUs with below parameters:
CONFIG_SLAB=y
kfree_loops=200000 kfree_alloc_num=1000 kfree_rcu_test=1
102898760401 ns, loops: 200000, batches: 5822, memory footprint: 158MB
89947009882 ns, loops: 200000, batches: 6715, memory footprint: 115MB
rcuperf shows approximately ~12% better throughput(Total time)
in case of using "bulk" interface. The "drain logic" or its RCU
callback does the work faster that leads to better throughput.
