GP100's page table nests a lot more deeply than the GF100-compatible layout we're currently using, which means our hackish-but-simple way of dealing with BAR2 VMM teardown won't work anymore. In order to sanely handle the chicken-and-egg (BAR2's PTs get mapped into themselves) problem, we need prevent page tables getting mapped back into BAR2 during the destruction of its VMM. To do this, we simply key off the state that's now maintained by the BAR2 init/fini functions. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
