[Nouveau] [PATCH 1/6] drm/ttm: rework on ttm_resource to use size_t type

Am 19.10.22 um 17:27 schrieb Somalapuram Amaranath:> Change ttm_resource structure from num_pages to size_t size in bytes.
When you remove the num_pages field (instead of adding the size 
additionally) you need to change all drivers in one patch.

Otherwise the build would break in between patches and that's not 
something we can do.

Please use bo->base.size here. The resource size can actually be larger 
than the BO size, but the extra space shouldn't be CPU map-able.

I think we can remove the local variable now, or is that used in some 
kind of loop?

Thanks,

Here bo->tbo.base.size would make more sense, but apart from that the 
patch looks good to me.

I'm not an expert for nouveau so it might be possible that we better use 
bo->base.size instead of bo->resource->size at some places. But that
can
be cleaned up later if anybody really cares.

I think you can drop the conversion and PFN_UP. What we need here is a 
compare result. Something like this:

if (la->robj->tbo.resource->size >
lb->robj->tbo.resource->size)
 ??? return 1;
if (la->robj->tbo.resource->size <
lb->robj->tbo.resource->size)
 ??? return -1;
return 0;

And I think it makes more sense to use tbo.base.size here as well 
instead of the resource size.

Regards,
Christian.
