Looks like this was added in 8.0.22, https://github.com/mysql/mysql-server/commit/6653b43360e0819906dc9272797948abaf22b18c. Please try building previous 8.x to confirm.

But in the end there is not much I can do for PPC.

    dev-db/mysql: keyword 8.0.26 for -riscv
    
    8.0.22+ rely on certain types having an always-lock-free property, which
    is (for now?) not the case on this arch.

[Comment 5 Sam James 2021-10-16 02:48:34 UTC]

This doesn't help ppc, but Debian are applying:

* https://sources.debian.org/patches/mysql-8.0/8.0.23-3/atomic-test-words.patch/ (-latomic fix)
and
* https://sources.debian.org/patches/mysql-8.0/8.0.23-3/use-largest-lock-free-type-selector-on-riscv.patch/

I am not able to say if the latter patch would help on PPC at all and honestly I don't think we care (in a nice way). I think we're better off pursuing keeping MariaDB working on PPC instead given it's an older arch.

The patch is kind of invasive so I don't know if Whissi will want to apply it, but it might be OK if just applied on riscv + tests pass as a result. Not sure.

With these two patches, it compiles successfully on riscv, but some router tests fail with missing atomic on runtime (maybe because some of them are linked as MODULE in cmake). I have improved the atomic patch to make it less invasive and the test pass. 

Additionally, a cycle timer implementation is required like mariadb https://github.com/MariaDB/server/pull/1981 otherwise there is timer warning that causes all tests to fail. I also include the patch here.

With these patches, there are still some ```Could not get local host address: Name or service not known``` fails in router unit tests. I am not sure if it is related to my environment.

hi @mysql team
 ping, can we include these two patches? which at #c10, #c11, since upstream already merged..
 or anything still need to do? just let us know..

[Comment 13 Yixun Lan 2022-01-31 11:18:07 UTC]

hi @alexfanqi

please format the patch a little bit
1) give the signed-off (preserve upstream's author info, or add yours)
2) add commit message, document what's the status (if possible)
3) maybe additional info (URL links, etc..)

hi @mysql,
ping, I create a PR to include those two patches from @alexfanqi, basically it only touch RISC-V, so should be quite safe for other ARCHs

and if there is no objection, I will commit in one week myself (2022/02/07), thanks

this one is also required for RISC-V, I've updated PR to include it.
it may sound invasive, but in fact it only touch RISC-V, so pretty safe

[Comment 18 Thomas Deutschmann (RETIRED) 2022-02-04 17:57:05 UTC]

I'll pick this up with next version bump which is pending, no rev bump for this. Thanks.
