Linux kernel source tree
1e32ffbc9d
Currently we can run into issues with provisioning VRAM region, due to requiring contig VRAM BO underneath. We sometimes see that allocation (multiple GB) can fail even when there is enough free space. We don't need CPU access to the buffer in the first place, so can forgo pin_map and therefore also the contig requirement. Keep the same behavior with save and restore during suspend/resume (which can now be done with blitter). We also need the VRAM to occupy the same pages so we don't need to re-program the LMTT, so should still remain pinned (also we don't want something to try evict it). With that covert over to plain pinned kernel object.

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 reStructuredText 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.
