In the end, I found several font-related issues which also affected the results on other platforms. The cause of the font problem on Fedora 27 is the introduction of URW++ v2 font family. It is not compatible with fixfonts.sh's font conversion. Another problem on Fedora 27 is that ghostscript 9.22 does not work with a2ping script. I reported the issue to Red Hat Bugzilla [1]. So far, it has not been resolved. a2ping issue is not touched in this patch set. [1]: https://bugzilla.redhat.com/show_bug.cgi?id=1530268 Patch #1 adds a font conversion script for .svg files. In some .svg files, non-free font names such as "Helvetica" and "Courier" are used. Also, a generic font name of "Sans" causes the result to depend on locale setting. Converting those names to URW font- family names can eliminate the ambiguity. It also adds a recipe to convert fonts in .eps files which are the origin of figures (mostly generated by gnuplot). Patch #2 fixes fixfonts.sh to avoid unintended conversions. Patch #3 fixes font names embedded in .eps files which look like the result of wrong conversion before they were committed. Patch #4 adds conversion scripts for URW++ v2 font family. Which set of scripts to use is determined in Makefile according to the result of "fc-list" command. These changes have been tested on Ubuntu Trusty, Ubuntu Xenial, Fedora 26, and Fedora 27 (with ghostscript downgraded to 9.20). Differences in the resulting figures can be seen in Figures 9.1, 9.7, 9.8, 17.5, and 17.6. You need to do "make neatfreak; make -j4" to ensure all the affected figures to be rebuilt. Thanks, Akira NOTE 1: After KPTI was applied, ghostscript slowed down significantly on virtual guest machines (might as well on real machines). NOTE 2: Before this change, full rebuild on Ubuntu Trusty with small RAM size (<2GB) sometimes ended up in DOS (thrashing). Now this symptom has disappeared. -- Akira Yokosawa (4): Add fixsvgfonts.sh Fix pattern order in fixfonts.sh future: Fix embedded font name in .eps files Makefile: Support URW++ v2 font family names Makefile | 38 +++++++++++++++++++++---- future/be-lb-n4-rf-all.eps | 4 +-- future/be-lw-n4-rf-all.eps | 4 +-- future/latencytrend.eps | 4 +-- utilities/fixanepsfonts-urwps.sh | 27 ++++++++++++++++++ utilities/fixfonts-urwps.sh | 61 ++++++++++++++++++++++++++++++++++++++++ utilities/fixfonts.sh | 28 ++++++++++++++---- utilities/fixsvgfonts-urwps.sh | 23 +++++++++++++++ utilities/fixsvgfonts.sh | 15 ++++++++++ 9 files changed, 187 insertions(+), 17 deletions(-) create mode 100644 utilities/fixanepsfonts-urwps.sh create mode 100644 utilities/fixfonts-urwps.sh create mode 100644 utilities/fixsvgfonts-urwps.sh create mode 100644 utilities/fixsvgfonts.sh -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe perfbook" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
