Subject: Help needed with hugepages
Date: Wed, 23 Oct 2024 16:04:06 +0100 [thread overview]
Message-ID: <CAJK_iehzaOoGS48PSj1h9n4AK6GEaDP2CPxkBZUrK6rYhYLFxQ@mail.gmail.com> (raw)
Hi, we are running on Ubuntu 24.04. The kernel parameters include:
default_hugepagesz=1G hugepagesz=1G hugepages=25 hugepagesz=2M hugepages=1024
No mount point is specified for the huge pages as secondary process
support is not required.
The o/s reports:
$ cat /proc/meminfo | grep HugePages_Total
HugePages_Total: 25
$ cat /proc/meminfo | grep Hugepagesize
Hugepagesize: 1048576 kB
Why does it not report the 2M pages?
When our application runs I see:
EAL: 1024 hugepages of size 2097152 reserved, but no mounted hugetlbfs
found for that size
Is that an error condition?
Best regards
David
