[linux-yocto] [PATCH] common-pc: enable support for bochs vga interface (qemu stdvga)

2019-08-12 Thread Alexander Kanavin 
This will enable standardizing qemu machines to '-vga std' emulated
hardware (as opposed to the current mix of vmware or cirrus cards,
both outdated).

See https://bugzilla.yoctoproject.org/show_bug.cgi?id=13466 for details.

Re: [linux-yocto] how to add recipe-sysroot-native to PKG_CONFIG_PATH for linux-yocto

2019-05-14 Thread Alexander Kanavin 
You probably need to add a dependency on glib-2.0 to your recipe, then
the needed pkgconfig will be in the target sysroot.

If you can copy-paste the entire recipe, that would help.

Thanks. I'm new to this - why is the patch in version branches, but
not in master?
