Move the template files to be in the same directory as the rvgen package. Furthermore, the installation will now only install the templates to the package directory, not /usr/share/. This simplify templates reading, as the scripts do not need to find the templates at multiple places. 2. Move dot2k_templates/* to: - templates/dot2k/ - templates/container/ This allows sharing templates reading code between DA monitor generation and container generation (and any future generation type). For template files which can be shared between different generation types, support putting them in templates/ This restructure aligns with the recommendation from: https://python-packaging.readthedocs.io/en/latest/non-code-files.html Reviewed-by: Gabriele Monaco Signed-off-by: Nam Cao --- tools/verification/rvgen/Makefile | 5 +- tools/verification/rvgen/rvgen/dot2k.py | 47 ++++++++----------- .../templates}/Kconfig | 0 .../templates/container/Kconfig} | 0 .../templates/container/main.c} | 0 .../templates/container/main.h} | 0 .../templates/dot2k}/main.c | 0 .../templates/dot2k}/trace.h | 0 8 files changed, 20 insertions(+), 32 deletions(-) rename tools/verification/rvgen/{dot2k_templates =3D> rvgen/templates}/Kco= nfig (100%) rename tools/verification/rvgen/{dot2k_templates/Kconfig_container =3D> rv= gen/templates/container/Kconfig} (100%) rename tools/verification/rvgen/{dot2k_templates/main_container.c =3D> rvg= en/templates/container/main.c} (100%) rename tools/verification/rvgen/{dot2k_templates/main_container.h =3D> rvg= en/templates/container/main.h} (100%) rename tools/verification/rvgen/{dot2k_templates =3D> rvgen/templates/dot2= k}/main.c (100%) rename tools/verification/rvgen/{dot2k_templates =3D> rvgen/templates/dot2= k}/trace.h (100%) diff --git a/tools/verification/rvgen/Makefile b/tools/verification/rvgen/M= akefile index cea9c21c3bce..8d08825e7e54 100644 --- a/tools/verification/rvgen/Makefile +++ b/tools/verification/rvgen/Makefile @@ -3,7 +3,6 @@ INSTALL=3Dinstall prefix ?=3D /usr bindir ?=3D $(prefix)/bin mandir ?=3D $(prefix)/share/man -miscdir ?=3D $(prefix)/share/rvgen srcdir ?=3D $(prefix)/src =20 PYLIB ?=3D $(shell python3 -c 'import sysconfig;
