The Yocto Project docs was migrated from Docbook to Sphinx in YP 3.2. This 3.1 is an LTS release, and since 3.1 docs are 'close to' the docs in 3.2, we agreed to backport sphinx docs onto 3.1. This first patch brings all changes done in 3.2 until: 7f64574f7 README: include detailed information about sphinx There are other changes after this commit, but they will be selectively backported in individual patches. This patch was generated with the following command: git cherry-pick -n \ $(git log --reverse --oneline \ ac352ad7f95db7eeacb53c2778caa31800bd7c26..7f64574f7 \ | cut -f1 -d' ') The following commits were applies in the dunfell docs, but not in master, so they were first reverted (and squashed into this change). A commit will reintroduce the content from these patches in the Sphinx files in a followup patch. 069c27574 Documenation: Prepared for the 3.1.1 release bd140f0f9 Documentation: Add 3.1.1 version updates missing from previous commit 17cc71a8f Documenation: Prepared for the 3.1.2 release 1a69e2c02 Documenation: Prepared for the 3.1.3 release 8910ac1c7 Documenation: Prepared for the 3.1.4 release (From yocto-docs rev: c25fe058b88b893b0d146f3ed27320b47cdec236) Signed-off-by: Nicolas Dechesne <nicolas.dechesne@linaro.org> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

<title>Slow Write Speed on Live Images</title>
|
|
|
|
<para>
|
|
In one of our previous releases (denzil), users noticed that booting
|
|
off of a live image and writing to disk was noticeably slower.
|
|
This included the boot itself, especially the first one, since first
|
|
boots tend to do a significant amount of writing due to certain
|
|
post-install scripts.

|
<para>
|
|
The problem (and solution) was discovered by using the Yocto tracing
|
|
tools, in this case 'perf stat', 'perf script', 'perf record'
|
|
and 'perf report'.
