Renesas BSP v3.5.1 (kernel v4.9 stable) [Environment] poky: yocto-2.1.2 (cca8dd15c8096626052f6d8d25ff1e9a606104a3) meta-openembedded: 55c8a76da5dc099a7bc3838495c672140cedb78e meta-linaro: 2f51d38048599d9878f149d6d15539fb97603f8f [Information] - U-boot: Changed load address from H'49000000 to H'50000000 - XDG_RUNTIME_DIR has been changed from "/run/user/root" to "/run/user/0" - Change location of include directory, which stores common user header files, to $(INCSHARED) - In BSP Only, core-image-weston is not supported even though local-wayland.conf is provided. - Please set Salvator-x SW7 Pin-1. In after Yocto BSP v2.12.0, it is  necessary to enable BKUP_TRG signal for Suspend to RAM. - The dtb filename was changed in R-Car H3. Only "Image-r8a7795-es1-salvator-x.dtb" is supported in this version. Please use "Image-r8a7795-es1-salvator-x.dtb" It supports R-Car H3 WS1.0 and WS1.1. - Please update your local.conf and bblayers.conf corresponding to Yocto v2.16.0 package. You can refer to meta-rcargen3/docs/sample/conf/ for updated contents. - You have to re-compile out-of-recipe software like user application by v2.16.0 SDK toolchains. - In some boards, the resuming from System Suspend to RAM may cause unstable operation or failed to resume.

+From d02226b3d5872b184c1d50c7f4706ac9467ffb81 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] weston-launch: Provide a default version that doesn't require
+ PAM
+
+weston-launch requires PAM for starting weston as a non-root user.
+
+Since starting weston as root is a valid use case by itself, if
+PAM is not available, provide a default version of weston-launch
+without non-root-user support.
+
+Upstream-Status: Pending
