From 11baad35088dfd4bdabc1710df650dbfb413e7a3 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Kristian=20H=C3=B8gsberg?= Date: Tue, 21 Jan 2014 12:17:03 -0800 Subject: [PATCH] intel: Fix initial MakeCurrent for single-buffer drawables MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Commit 05da4a7a5e7d5bd988cb31f94ed8e1f053d9ee39 attempts to eliminate the call to intel_update_renderbuffer() in the case where we already have a drawbuffer for the drawable. Unfortunately this only checks the back left renderbuffer, which breaks in case of single buffer drawables. This means that the initial viewport will not be set in that case. Instead, we now check whether the initial viewport has not been set, in which case we call out to intel_update_renderbuffer(). https://bugs.freedesktop.org/show_bug.cgi?id=73862 Signed-off-by: Kristian Høgsberg --- src/mesa/drivers/dri/i965/brw_context.c | 10 ++++------ 1 file changed, 4 insertions(+), 6 deletions(-) diff --git a/src/mesa/drivers/dri/i965/brw_context.c b/src/mesa/drivers/dri/i965/brw_context.c index fd0ea547dbd..b54ef1f5a73 100644 --- a/src/mesa/drivers/dri/i965/brw_context.c +++ b/src/mesa/drivers/dri/i965/brw_context.c @@ -918,7 +918,6 @@ intelMakeCurrent(__DRIcontext * driContextPriv, if (driContextPriv) { struct gl_context *ctx = &brw->ctx; struct gl_framebuffer *fb, *readFb; - struct intel_renderbuffer *rb = NULL; if (driDrawPriv == NULL && driReadPriv == NULL) { fb = _mesa_get_incomplete_framebuffer(); @@ -926,7 +925,6 @@ intelMakeCurrent(__DRIcontext * driContextPriv, } else { fb = driDrawPriv->driverPrivate; readFb = driReadPriv->driverPrivate; - rb = intel_get_renderbuffer(fb, BUFFER_BACK_LEFT); driContextPriv->dri2.draw_stamp = driDrawPriv->dri2.stamp - 1; driContextPriv->dri2.read_stamp = driReadPriv->dri2.stamp - 1; } @@ -938,11 +936,11 @@ intelMakeCurrent(__DRIcontext * driContextPriv, intel_gles3_srgb_workaround(brw, fb); intel_gles3_srgb_workaround(brw, readFb); - if (rb && !rb->mt) { - /* If we don't have buffers for the drawable yet, force a call to - * getbuffers here so we can have a default drawable size. */ + /* If the context viewport hasn't been initialized, force a call out to + * the loader to get buffers so we have a drawable size for the initial + * viewport. */ + if (!brw->ctx.ViewportInitialized) intel_prepare_render(brw); - } _mesa_make_current(ctx, fb, readFb); } else { -- 2.30.2
