Hi,
Obviously old userspace + new kernel combo needs to be supported. But I'm not so sure about a mixed case, does old userspace + new userspace need to be supported to run at the same time?
For example, a new 64-bit mesa+libdrm and a 32-bit old set, both running apps at the same time.
Or is it acceptable to assume that once a new userspace has been run, an old one won't be run for this boot?
old 32b userspace in a chroot, for example?
Maybe you can give a better description of what you are wanting to do? Could you decide on 32b vs 64b userspace on a per 'struct drm_file' basis (ie. each time /dev/dri/cardN is opened)?
