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
