Every access to either the GTT or CPU pointer is supposed to be proceeded by a set_domain ioctl so that GEM is able to manage the cache domains correctly and for the following access to be coherent. Of course, some people explicitly want incoherent, non-blocking access which is going to trigger warnings by this patch but are probably better served by explicit suppression. v2: Also mark the pointers as inaccessible following the explicit unmap and implicit unmap upon return to the cache.

libdrm - userspace library for drm This is libdrm, a userspace library for accessing the DRM, direct rendering manager, on Linux, BSD and other operating systes that support the ioctl interface. The library provides wrapper functions for the ioctls to avoid exposing the kernel interface directly, and for chipsets with drm memory manager, support for tracking relocations and buffers. libdrm is a low-level library, typically used by graphics drivers such as the Mesa DRI drivers, the X drivers, libva and similar projects. New functionality in the kernel DRM drivers typically requires a new libdrm, but a new libdrm will always work with an older kernel. Compiling --------- libdrm is a standard autotools packages and follows the normal configure, build and install steps. The first step is to configure the package, which is done by running the configure shell script: ./configure By default, libdrm will install into the /usr/local/ prefix. If you want to install this DRM to replace your system copy, pass --prefix=/usr and --exec-prefix=/ to configure. If you are building libdrm from a git checkout, you first need to run the autogen.sh script. You can pass any options to autogen.sh that you would other wise pass to configure, or you can just re-run configure with the options you need once autogen.sh finishes. Next step is to build libdrm: make and once make finishes successfully, install the package using make install If you are install into a system location, you will need to be root to perform the install step.
