From a7ee842acd30578f4170f69124c3986ee35a6df8 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Tue, 1 Jul 2014 15:37:56 +0200 Subject: [PATCH] llvmpipe: get rid of llvmpipe_get_texture_tile_linear Because the layout is always linear this didn't really do much any longer - at some point this triggered per-tile swizzled->linear conversion. The x/y coords were ignored too. Apart from triggering conversion, this also invoked alloc_image_data(), which could only actually trigger mapping of display target resources. So, instead just call resource_map in the callers (which also gives the ability to unmap again). Note that mapping/unmapping of display target resources still isn't really all that clean (map/unmap may be unmatched, and all such mappings use the same pointer thus usage flags are a lie).
