From: Kenneth Graunke Date: Tue, 27 Feb 2018 07:17:35 +0000 (-0800) Subject: i965: Generalize intel_upload.c to support multiple uploaders. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=eb99bf8abe367aaf01ccf50347b510d8cfb87688;p=mesa.git i965: Generalize intel_upload.c to support multiple uploaders. I'd like to reuse the upload logic for a new program cache, but the buffers will need to have a different lifetime than the default uploader, and also some address space restrictions. So, we can't use a single uploader for both situations - we'll need two of them. This creates a public 'uploader' structure, and adjusts the interface to take an uploader rather than always using brw->upload. It should have no functional change at the moment.
