[opensource-dev] Question about BUG-41029 and 64 bit usage

[Cinder Roxley]

Mine has 6GB and was relatively inexpensive ($211 USD)

As far as the viewer, I think the best way to go would be to bite the bullet and rework those to use size_t.

Yep - I saw a lot of memory related texture references too - I don't know if cards these days have more than 4GB of video memory - definitely a possibility soon if not already.

Funny, i just so happened to stumble across this a few days ago when i had this mindblowing realization that this might be the cause for the Viewer not properly reporting VRAM over 4gb but i don't happen to have a 4+gb VRAM GPU so i wouldn't be able to test anything i do and ultimately dropped the idea of touching it for now.

I'm taking a look at https://jira.secondlife.com/browse/BUG-41029and whilst it seems straightforward, it seems to be unraveling into something that touches dozens of files and I wondered if someone had done this work already.

There is a lot usage of 32 bit types (U32Bytes, U32Megabytes etc.) defined indirectly here: 

https://bitbucket.org/lindenlab/viewer64/src/9270caf3d4324f9c1c33aa158f80e0fe84036a48/indra/llcommon/llunittype.h?at=default&fileviewer=file-view-default#llunittype.h-824

that are used to count memory sizes/usage/difference etc.  I think we can convert them to their U64 equivalents for all viewers. 

Nat points out, rewriting this code using size_t as a return type would make more sense but that seems like it would involve more invasive code changes including changes in fundamental LL headers.

What does the collective wisdom say?
