-- * Option: UseCPA

-  * Description:
-  *
-- * Many kernels have a broken implementation of change_page_attr that leads
-- * to cache aliasing problems. x86_64 kernels between 2.6.0 and 2.6.10 will
-- * force a kernel BUG_ON() when this condition is encountered. For this
-- * reason, the NVIDIA driver is very careful about not using the CPA kernel
-- * interface on these kernels.
-- *
-- * Some distributions have backported this fix to kernel versions that fall
-- * within this version range. The NVIDIA driver attempts to automatically
-- * detect these fixes and reenable usage of the change_page_attr interface.
-- *
-- * Due to the serious nature of the problems that can arise from this, the
-- * NVIDIA driver implements a manual registry key to force usage of this API
-- * to be enabled or disabled. This registry key can be used to force usage
-- * of the API on a known fixed kernel if the NVIDIA driver fails to detect
-- * the kernel as fixed. This registry key can also be used to disable usage
-- * of the API on a bad kernel that is misdetected as a fixed kernel.
-- *
-- * The default value is '-1' (use NVIDIA driver default logic)
-- * A value of '0' will forcibly disable change_page_attr calls.
-- * A value of '1' will forcibly enable change_page_attr calls.
-+ * Many kernels have broken implementations of the change_page_attr()
-+ * kernel interface that may cause cache aliasing problems. Linux/x86-64
-+ * kernels between 2.6.0 and 2.6.10 may prompt kernel BUG()s due to
-+ * improper accounting in the interface's large page management code, for
-+ * example. For this reason, the NVIDIA Linux driver is very careful about
-+ * not using the change_page_attr() kernel interface on these kernels.
-+ *
-+ * Due to the serious nature of the problems that can arise from bugs in
-+ * the change_page_attr(), set_pages_{uc,wb}() and other kernel interfaces
-+ * used to modify memory types, the NVIDIA driver implements a manual
-+ * registry key override to allow forcibly enabling or disabling use of
-+ * these APIs.
-+ *
-+ * Possible values:
-+ *
-+ * ~0 = use the NVIDIA driver's default logic (default)
-+ *  0 = enable use of change_page_attr(), etc.
-+ *  1 = disable use of change_page_attr(), etc.
-+ *
-+ * By default, the NVIDIA driver will attempt to auto-detect if it can
-+ * safely use the change_page_attr() and other kernel interfaces to modify
-+ * the memory types of kernel mappings.
