As the userspace mappings are torn down on every GPU write, we prefer to track when the buffer is activated (via a fresh i915_gem_fault). This makes the LRU conceptually simpler. With coherent mappings, the remaining use-case for set_domain_ioctl is GPU synchronisation. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> |
