The idea is from commita50fe70780("drm/amdkfd: Only apply heavy-weight TLB flush on Aldebaran") and commitf61c40c075("drm/amdkfd: enable heavy-weight TLB flush on Arcturus"). At the moment, heavy-weight TLB could cause problems on ASICs except Aldebaran and Arcturus. A simple hipMallocManaged/hipFree program could trigger this issue.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
