= RISC-V AP-TEE TG Specifications

This repository is for specification deliverables of the AP-TEE TG per the proposed https://github.com/riscv-non-isa/riscv-ap-tee/blob/main/charter.adoc[charter]. The specification(s) are not ratified and everything in these documents may change.

= License

This work is licensed under a Creative Commons Attribution 4.0 International License (CC-BY-4.0). 

See the https://github.com/riscv/docs-spec-template/blob/main/LICENSE[LICENSE] file for details.

= Contributors

Contributors to this specification are contained in the link:src/contributors.adoc[contributors] file.

= Dependencies

This project is built using AsciiDoctor (Ruby). The repository has been setup to build the PDF on

checkin using GitHub actions. Workflow dependencies are located in the `dependencies` directory.

For more information on AsciiDoctor, specification guidelines, or building locally, see the

https://github.com/riscv/docs-dev-guide[RISC-V Documentation Developer Guide].

= Cloning the project

This project uses https://git-scm.com/book/en/v2/Git-Tools-Submodules[GitHub Submodules]

to include the https://github.com/riscv/docs-resources[RISC-V docs-resources project]

to achieve a common look and feel.

When cloning this repository for the first time, you must either use 

`git clone --recurse-submodules` or execute `git submodule init` and `git submodule update` after the clone to populate the docs-resources directory. Failure to clone the submodule, will result

in the PDF build fail with an error message like the following:

    $ make

    asciidoctor-pdf \

    -a toc \

    -a compress \

    -a pdf-style=docs-resources/themes/riscv-pdf.yml \

    -a pdf-fontsdir=docs-resources/fonts \

    --failure-level=ERROR \

    -o profiles.pdf profiles.adoc

    asciidoctor: ERROR: could not locate or load the built-in pdf theme `docs-resources/themes/riscv-pdf.yml'; reverting to default theme

    No such file or directory - notoserif-regular-subset.ttf not found in docs-resources/fonts

      Use --trace for backtrace

    make: *** [Makefile:7: profiles.pdf] Error 1 

= Building the document

The final specification form of PDF can be generated using the `make` command.
