With etnaviv not being tied into the IOMMU framework anymore, the MMU functions will only be called under sleeping locks. Thus we are able to allocate the memory for the 2nd level page tables on demand without having to deal with memory allocation in atomic context. This speeds up driver intitialization on MMUv2 GPU cores, as we don't need to preallocate all the page table memory and also reduces memory consumption for most workloads, as most of them won't use the full GPU virtual address space.

README
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 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.
