Chromium on POWER

This repository contains a set of patches that allow the Chromium browser to build and run on ppc64le hosts.

In addition, this repository contains an interactive utility for automatically applying and rebasing patches to a given chromium source tree.

Layout

Individual patches are roughly grouped by the part of chromium they modify. For example, patches for the sandbox system can be found in the sandbox folder.

patches.json contains a manifest of all of the patches. In this file, patches are grouped by the directory that they must be applied in, relative to the chromium source directory.

For example, patches under "." are to be applied in the root chromium source directory, and patches under "v8" are to be applied in <chromium source root>/v8.

Chromium Patching Framework

cpf.py contains the Chromium Patching Framework, an interactive utility for applying and rebasing patches to a given source tree.

To apply all patches listed in the manifest to a local copy of the chromium source tree, do the following:

./cpf.py /path/to/chromium/tree

Example output:

[+] Applying "sandbox/0001-linux-seccomp-bpf-ppc64-glibc-workaround-in-SIGSYS-h.patch"... Success
[+] Applying "sandbox/0001-sandbox-Enable-seccomp_bpf-for-ppc64.patch"... Success

[+] Applying "sandbox/0001-sandbox-linux-Implement-partial-support-for-ppc64-sy.patch"... Success

If an error is encountered, you will be prompted with the following options:
