From: Kenneth Graunke Date: Thu, 26 Sep 2013 00:01:55 +0000 (-0700) Subject: i965: Move hardware limits to brw_device_info. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d76f6c7ae4d738193af2b3a06c4e6321e5e4daac;p=mesa.git i965: Move hardware limits to brw_device_info. Since each kind of device has its own brw_device_info structure, we can simply store the URB and thread limits there. This eliminates all the large if-ladders, and simplifies the context initialization code quite a bit.
