Subject: amd: fix tile_swizzle on gfx11 - should be shifted by 10 bits, not 8
X-Git-Tag: upstream/22.3.5~34
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2da08ed347dc5f730caa46ebba5444a9bd2b344f;p=platform%2Fupstream%2Fmesa.git

amd: fix tile_swizzle on gfx11 - should be shifted by 10 bits, not 8

This reverts the radv_adjust_tile_swizzle change to unify the code.

Fixes: 529eb739fc4 - radeonsi/gfx11: add CB deltas
