[OE-core] [PATCH] mesa: use x11 as egl_native_platform when the configure argument "platforms" contains x11
From: Quanyang Wang
This fixes an issue that the mesa egl library detecting the wrong
platform type.

---
When mesa update from 19.1 to 20.0, there is an issue that the mesa egl
will detect the wrong platform type, this issue results that in the sato
X11 window system all opengl/opengles apps by using egl run into
"Segmentation fault".
I have filed a bug to mesa community:
https://gitlab.freedesktop.org/mesa/mesa/-/issues/3075#note_519060
Until now there is no response from the developers.
There are several solutions to resolve it:
1) When running an openg/opengles app in sato, export
EGL_PLATFORM="x11".
2) Adjust the configure argument order in mesa.inc to make
"-Dplatforms=wayland,x11,drm,surfaceless"
to be "-Dplatforms=x11,wayland,drm,surfaceless" to dodge this issue.
3) Apply this patch for a workaround then waiting for mesa development
community to work out a perfect solution.

+Subject: [PATCH] meson: use x11 as egl_native_platform when the configure
+ argument "platforms" contains x11
+
+When mesa is configured with argument
"-Dplatforms=wayland,x11,drm,surfaceless",
+in meson.build, the "wayland" is the first element of "platforms" and the
+"egl_native_platform" will be "wayland", then in src/egl/meson.build,
+_EGL_NATIVE_PLATFORM will be assigned to be _EGL_NATIVE_WAYLAND. And in the
+commit 86d3a346 ("egl: fix _EGL_NATIVE_PLATFORM fallback"), the function
+_eglNativePlatformDetectNativeDisplay delete the return value _EGL_PLATFORM_X11
+when detecting "wayland" and "gbm" failed, this will result that in
_eglGetNativePlatform
+the platform type will be _EGL_NATIVE_PLATFORM which is equal to be
_EGL_NATIVE_WAYLAND
+even if the app runs at a "X11" platform.
+
+So when an X11 app using egl:
+x_dpy = XOpenDisplay(NULL);
+...
+dpy = eglGetDisplay((EGLNativeDisplayType) x_dpy);
+eglGetDisplay will run into crash because libEGL.so detected the wrong
platform type.
+
+root@genericx86-64:~# export DISPLAY=:0
+root@genericx86-64:~# eglgears_x11
+Segmentation fault
+
+When apps run at wayland or gbm platform, eglGetDisplay can detect the
platform type
+automatically, but x11 can't. So use x11 as egl_native_platform when the
configure
+argument "platforms" contains x11.

[OE-core] [PATCH v2] kexec-tools: fix arm kexec failure for __NR_kexec_file_load
From: Wang Quanyang
Once use kexec in arm arch, it will throw out the error info as below:
Could not find a free area of memory of 0xc78e744 bytes...
This is because that kexec use kexec_file_load to load image by default
but arm doesn't support it. So add this patch to avoid use kexec_file_load
in arm platforms.

+In the kernel upstream commit 4ab65ba7a5cb
+("ARM: add kexec_file_load system call number"),
+__NR_kexec_file_load for arm has been defined to be 401.
+This results that even if kexec_file_load isn't implemented

This is because that kexec use kexec_file_load to load image by default
but arm doesn't support it. So add this patch to avoid use kexec_file_load
in arm platforms.

+Subject: [PATCH] kexec/arm: undefine __NR_kexec_file_load for arm
+
+In the kernel upstream commit 4ab65ba7a5cb
+("ARM: add kexec_file_load system call number"),
+__NR_kexec_file_load for arm has been defined to be 401.
+This results that even if kexec_file_load isn't implemented
+for arm but the function is_kexec_file_load_implemented()
+will still return true. So undef __NR_kexec_file_load for
+arm architecture.

[OE-core] weston-init: run login before start weston.service
From: Wang Quanyang When systemd start the weston.service, the script "weston-start" will check if the dir "XDG_RUNTIME_DIR" (usually is /run/user/0) exits and create it. Then weston will create a socket file "wayland-0" for communications with clients in this dir. If systemd is built with enabling "pam" feature, the login will call "run-user-0.mount" to mount tmpfs at the dir "/run/user/0", then the socket file "wayland-0" will be missing since it is created in the old "/run/user/0". So add "PAMName=login" to let weston.service call login first, once tmpfs is mounted at "/run/user/0", then call weston-start to create a socket file in it.
