Testing related miniconf during Zephyr Summit

Perkowski, Maciej
 

Hi,
I started a gh discussion so we (the people presenting during testing miniconf) can sync up the topics we’d like to cover/be covered. https://github.com/zephyrproject-rtos/zephyr/discussions/35845 If you have any comments/ideas/suggestions related to the miniconf, please share them in this discussion.

Hi Alex,

 

By last night’s meeting, below is the guide on how to use 3rd party tool-chain.

I'm not an expert in NFS by any means, but looking at its description here https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Software/ONTAP_OS/What_is_the_NFSv3_mount_%22noac%22_option%3F I'm not sure if it's going to make a difference.

 

What worries me is all the "computations" happen locally on the same machine, it's only tools that are being used are located on NFS share. So since there's no distributed (between multiple clients) execution of say "twister" script, why top-level VFS capabilities are not enough here?

Hi Hake, all,

 

Our scenario for build problem reproduction is quite simple:

  1. Zephyr SDK installed on NFS share
  2. Massively parallel execution, e.g. 10 instances of "twister" script building & running entire test-suite for all QEMU platforms.

If we move Zephyr SDK right to the build machine the issue goes away.

Use of simulated platforms is important because their executions happen in parallel, while execution on a real target boards is gated by very limited amount of available boards (we may have a few, but not 10s or even 100s).

 

Another interesting observation is with use of the same one technical user for execution of all "twister" instances (and subsequently all children processes) we quite early hit a limit of processes existing simultaneously for 1 user. On our servers we have "max user processes" ("ulimit -u") set to 4096 by default. And so the first thing we learned it's necessary to set it to something much higher, which we don now to get NFS-related problem reproduced.

 

Now, NFS-related problem seem to be related to some issues with synchronization as at some point we get a lot of python processes waiting for something with the following stack-trace:

---------------------->8----------------------

$ cat /proc/30876/stack

[<ffffffff9a912076>] futex_wait_queue_me+0xc6/0x130

[<ffffffff9a912e1b>] futex_wait+0x17b/0x280

[<ffffffff9a914b66>] do_futex+0x106/0x5a0

[<ffffffff9a915080>] SyS_futex+0x80/0x190

[<ffffffff9af8dede>] system_call_fastpath+0x25/0x2a

[<ffffffffffffffff>] 0xffffffffffffffff

---------------------->8----------------------

 

We're still in progress of debugging that. Once we have more data, we'll happily share it!

Hi All,

 

Todays weekly meeting agenda

 

Follow up last weekly meeting

 

1.     Mcuboot can be ROM?

2.     Multi-branch checking in parallel. Alex, do you send out your scenario summary?

3.     https://github.com/zephyrproject-rtos/zephyr/issues/34571

according to my experiences, it is because your board uart output some exception character which looks like a EOF to console handler.

 

 

General topics:

 

1.     V.2.6.0 board testing discussion.

a)      Any common pending issues found in this release?

 

  1. Zephyr summit topic discussion

https://github.com/zephyrproject-rtos/zephyr/wiki/2021-Zephyr-Developer-Summit

 

3.     Round table discussion

Hake

  1. Zephyr SDK installed on NFS share
  2. Massively parallel execution, e.g. 10 instances of "twister" script building & running entire test-suite for all QEMU platforms.

If we move Zephyr SDK right to the build machine the issue goes away.

Use of simulated platforms is important because their executions happen in parallel, while execution on a real target boards is gated by very limited amount of available boards (we may have a few, but not 10s or even 100s).

 

Another interesting observation is with use of the same one technical user for execution of all "twister" instances (and subsequently all children processes) we quite early hit a limit of processes existing simultaneously for 1 user. On our servers we have "max user processes" ("ulimit -u") set to 4096 by default. And so the first thing we learned it's necessary to set it to something much higher, which we don now to get NFS-related problem reproduced.

 

Now, NFS-related problem seem to be related to some issues with synchronization as at some point we get a lot of python processes waiting for something with the following stack-trace:

---------------------->8----------------------

$ cat /proc/30876/stack

[<ffffffff9a912076>] futex_wait_queue_me+0xc6/0x130

[<ffffffff9a912e1b>] futex_wait+0x17b/0x280

[<ffffffff9af8dede>] system_call_fastpath+0x25/0x2a

[<ffffffffffffffff>] 0xffffffffffffffff

---------------------->8----------------------

 

We're still in progress of debugging that. Once we have more data, we'll happily share it!

Hi All,

 

Todays weekly meeting agenda

 

Follow up last weekly meeting

 

1.     Mcuboot can be ROM?

2.     Multi-branch checking in parallel. Alex, do you send out your scenario summary?

3.     https://github.com/zephyrproject-rtos/zephyr/issues/34571

according to my experiences, it is because your board uart output some exception character which looks like a EOF to console handler.

 

 

General topics:

 

1.     V.2.6.0 board testing discussion.

a)      Any common pending issues found in this release?

 

  1. Zephyr summit topic discussion

https://github.com/zephyrproject-rtos/zephyr/wiki/2021-Zephyr-Developer-Summit

 

3.     Round table discussion

 

Regards,

Hake

I just remember we have file sync issue before, so try to add noac will disable the cache in nfs, which will downgrade the performance, but sync the files always.

I'm not an expert in NFS by any means, but looking at its description here https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Software/ONTAP_OS/What_is_the_NFSv3_mount_%22noac%22_option%3F I'm not sure if it's going to make a difference.

 

What worries me is all the "computations" happen locally on the same machine, it's only tools that are being used are located on NFS share. So since there's no distributed (between multiple clients) execution of say "twister" script, why top-level VFS capabilities are not enough here?
