I have been looking into a regression for Linux v6.18-rc where time taken to
run some internal graphics tests on our Tegra234 device has increased from
around 35% causing the tests to timeout. Bisect is pointing to this commit
and I also see we have CONFIG_KVFREE_RCU_BATCHED=y.
Thanks for reporting! Uh, this has been put aside while I was busy working
on other stuff... but now that we have two people complaining about this,
I'll allocate some time to investigate and improve it.
It'll take some time though :)
By the way, how many CPUs do you have on your system, and does your
kernel have CONFIG_CODE_TAGGING enabled?
For this device there are 12 CPUs. I don't see CONFIG_CODE_TAGGING enabled.
Thanks
