i915 is the only driver using those fields in the drm_gem_object
structure, so they only waste memory for all other drivers.
Move the fields into drm_i915_gem_object instead and patch the i915 code
with the following sed commands:
sed -i "s/obj->base.read_domains/obj->read_domains/g" drivers/gpu/drm/i915/*.c drivers/gpu/drm/i915/*/*.c
sed -i "s/obj->base.write_domain/obj->write_domain/g" drivers/gpu/drm/i915/*.c drivers/gpu/drm/i915/*/*.c
s/uint32_t/u16/ and plonk them next to
unsigned int cache_dirty:1;
Sure, no problem. Should I push this to drm-misc or should it go in
using some Intel tree?
How desperate are you? Can you wait until rc5 for the fields to
disappear?
I think this should be via drm-intel-next-queued, since nobody else has
a dependency. Otoh, you want it in early to ensure nobody else picks up
a dependency ;)
Well it's probably in there for years and nobody noticed, so I think we
can wait a bit longer as well :)
Going to send a V2 with your comments addressed soon.
Christian.
