[Why] We need DMCUB on Renoir to support DMCU and PHY initialization. The DMUB service provides a mechanism to load the DMCUB. [How] Include the DMUB service in amdgpu_dm. Frontdoor loading of the DMCUB firmware needs to happen via PSP. To pass the firmware to PSP we need to hand it off to the firmware list in the base driver during software initialization. Most of the DMUB service can technically be initialized at this point in time, but we don't want to be allocating framebuffer memory for hardware that doesn't support the DMCUB and in order to check that we need to be able to read registers - something DM helpers aren't setup to do in software initialization. So everything but the service creation itself will get deferred to hardware initialization.

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. 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.
