</div></div>Having a closer look at the patches related to external buffers, shows<br>
the following:<br>
<br>
2c4097aff1b i965: Only put external handles into the handle ht<br>
17.3 only<br>
<br>
d7a19d69ebc i965: Use PTE MOCS for all external buffers<br>
17.4 + 17.3<br>
4b1e70cc57d i965: Switch over to fully external-or-not MOCS scheme<br>
17.4 only<br>
<br>
344252a27f8 i965/bufmgr: Add a helper to mark a BO as external<br>
0a6a137eb27 i965: Mark BOs as external when we export their handle<br>
These fixes<br>
<br>
With the above in mind, it seems that 4b1e70cc57d should have been<br>
tagged for 17.3?<br></blockquote><div><br></div><div>It's not strictly necessary but probably makes back-porting easier. I'm fine with pulling it into 17.3.<br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
On the 17.2 front: Andres is right - commit 2c4097aff1b seems like a<br>
bare minimum for this series.<br>
Considering how well into the 17.2 series we are, I'm a bit worried<br>
about picking if :-\<br></blockquote><div><br></div><div>Agreed. <br></div></div></div></div>
