Hello,
I am facing issue related to CMA allocation failure of large size buffer.
I am beginner in Linux memory management. So I need your help to debug the issue,
I have below questions
1. Why migration failed ?
2. Who pinned the pages/Which process have pinned the pages ? How to identify that.
3. How to migrate pages forcefully so failure will avoid.(not preferable approach)
etc.
Any help would be appreciated.
Please let me know if you require further information.
Regards,
Pankaj
