Subject: Contiguous Memory Allocator (CMA)
Date: Tue, 21 Dec 2021 09:35:33 -0500	[thread overview]
Message-ID: <CADJuq2wCLDStwfiWSQNr9bNKjW5cqvGm_UkgKCpJ4E-GLXgkCQ@mail.gmail.com> (raw)

Hello
    Is CMA still supported as described in this document
https://lwn.net/Articles/396707/ ?
Or has it changed and there is a newer version which details how to
allocate a chunk of contiguous memory on bootup and then use it with a
loadable kernel module?
What I want to do is allocate a chunk of contiguous memory at boot time and
use it with a loadable driver.
It will be a vanilla Centos kernel and I wonder if they are compiled with
the CMA enabled.
When I check dmesg I see
 " 0K cma-reserved" so it still exists.

Thanks

S
