From bc92c0edf33f3f38275f6aa4e0639b3ddeef68ca Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Wed, 11 Feb 2009 10:48:36 +1000 Subject: drm/nv50: fix nv9x chipsets NVIDIA do this fun little sequence after updating the PRAMIN page tables. On 9xxx chips, none of the PRAMIN BAR bindings (except the initial one) worked, hence the majority of the setup needed to create a channel ended up in the wrong place, causing all sorts of fun. This is done by NVIDIA on nv8x chips also, so we'll do it for them too, even though they appear to work without it. --- shared-core/nv50_instmem.c | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/shared-core/nv50_instmem.c b/shared-core/nv50_instmem.c index b7a51f09..d76ebf38 100644 --- a/shared-core/nv50_instmem.c +++ b/shared-core/nv50_instmem.c @@ -297,6 +297,13 @@ nv50_instmem_bind(struct drm_device *dev, struct nouveau_gpuobj *gpuobj) vram += NV50_INSTMEM_PAGE_SIZE; } + NV_WRITE(0x070000, 0x00000001); + while(NV_READ(0x070000) & 1); + NV_WRITE(0x100c80, 0x00040001); + while(NV_READ(0x100c80) & 1); + NV_WRITE(0x100c80, 0x00060001); + while(NV_READ(0x100c80) & 1); + gpuobj->im_bound = 1; return 0; } -- cgit v1.2.3
