From 746df5671789aa5338c82a8e1b7fb50d342198e0 Mon Sep 17 00:00:00 2001 From: Felix Kuehling Date: Wed, 9 Mar 2005 15:28:47 +0000 Subject: If the texture image changed force emitting the texture address, even if it didn't change. This seems to flush texture cashes. Fixes multi-textured lighting in quake2. --- src/mesa/drivers/dri/savage/savagestate.c | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) (limited to 'src/mesa') diff --git a/src/mesa/drivers/dri/savage/savagestate.c b/src/mesa/drivers/dri/savage/savagestate.c index fd3da8262e..dd143f0949 100644 --- a/src/mesa/drivers/dri/savage/savagestate.c +++ b/src/mesa/drivers/dri/savage/savagestate.c @@ -1445,8 +1445,16 @@ static void savageEmitChangedRegChunk (savageContextPtr imesa, } static void savageUpdateRegister_s4(savageContextPtr imesa) { - /* the savage4 uses the contiguous range of BCI registers 0x1e-0x39 - * 0x1e-0x27 are local, no need to check them for global changes */ + /* In case the texture image was changed without changing the + * texture address as well, we need to force emitting the texture + * address in order to flush texture cashes. */ + if ((imesa->dirty & SAVAGE_UPLOAD_TEX0) && + imesa->oldRegs.s4.texAddr[0].ui == imesa->regs.s4.texAddr[0].ui) + imesa->oldRegs.s4.texAddr[0].ui = 0xffffffff; + if ((imesa->dirty & SAVAGE_UPLOAD_TEX1) && + imesa->oldRegs.s4.texAddr[1].ui == imesa->regs.s4.texAddr[1].ui) + imesa->oldRegs.s4.texAddr[1].ui = 0xffffffff; + savageEmitChangedRegs (imesa, 0x1e, 0x39); imesa->dirty=0; -- cgit v1.2.3
