In case of YF/YS tiled buffers libdrm need not know about the tiling
format because these buffers don't have hardware support to be tiled
or detiled through a fenced region. But, libdrm still need to know
about buffer alignment restrictions because kernel uses it when
resolving the relocation.
Mesa uses drm_intel_gem_bo_alloc_for_render() to allocate Yf/Ys buffers.
So, use the passed alignment value in this function to initialize the
align variable in drm_intel_bo. Note that we continue ignoring the
alignment value passed to drm_intel_gem_bo_alloc() to follow the
previous behavior.
V2: Add a condition to avoid allocation from cache. (Ben)
V3: Make no changes in cache allocation strategy. Just update the alignment.
Update the aperture size estimate including the alignment. (Ben, Chris)
V4: Move aperture size adjustments inside drm_intel_bo_gem_set_in_aperture_size()
Don't split sentences across the one-line header and the changelog. (Chris)

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.
