ASpeed distinguishes among various generations of the AST graphics chipset with various models. [1] The most-recent model AST 2600 is of the 7th generation, the AST 2500 is of the 6th generation, and so on. The ast driver simply picks one of the models as representative for the whole generation. In several places, individual models of the same generation need to be handled differently, which then requires additional code for detecting the model. Introduce different generations of the Aspeed chipset. In the source code, refer to the generation instead of the representation model where possible. The few places that require per-model handling are now clearly marked. In the enum ast_chip, we arrange each model's value such that it encodes the generation. This allows for an easy test. The actual values are ordered, but not of interest to the driver. v2: * use __ast_gen_is_eq() (Jingfeng) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://web.archive.org/web/20141007093258/http://www.aspeedtech.com/products.php?fPath=20 # 1 Reviewed-by: Jocelyn Falempe <jfalempe@redhat.com> Tested-by: Jocelyn Falempe <jfalempe@redhat.com> # AST2600 Reviewed-by: Sui Jingfeng <suijingfeng@loongson.cn> Link: https://patchwork.freedesktop.org/patch/msgid/20230621130032.3568-10-tzimmermann@suse.de
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.
