From b7a9222dc7492181588cedd62b94482fab8e9c95 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Michel=20D=C3=A4nzer?= Date: Mon, 13 Aug 2007 13:22:43 +0200 Subject: [PATCH] i915tex: Make sure pitch is aligned properly for render-to-texture. Just always align texture pitch to multiples of 64 bytes for now, pending a more sophisticated scheme to do it only when really necessary. --- src/mesa/drivers/dri/i915tex/intel_mipmap_tree.c | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) diff --git a/src/mesa/drivers/dri/i915tex/intel_mipmap_tree.c b/src/mesa/drivers/dri/i915tex/intel_mipmap_tree.c index fc38a28290d..74f6b2d8515 100644 --- a/src/mesa/drivers/dri/i915tex/intel_mipmap_tree.c +++ b/src/mesa/drivers/dri/i915tex/intel_mipmap_tree.c @@ -97,9 +97,19 @@ intel_miptree_create(struct intel_context *intel, break; } - if (ok) + if (ok) { + if (!mt->compressed) { + /* XXX: Align pitch to multiple of 64 bytes for now to allow + * render-to-texture to work in all cases.
