From 5f05cd7086c54bccf1c2f0b003b78a08dc55472a Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Sun, 24 Jun 2007 19:00:26 +1000 Subject: nouveau: NV04/NV10/NV20 PGRAPH engtab functions NV04/NV10 load_context()/save_context() are stubs. I don't know enough about how they work to implement them sanely. The "old" context_switch() code remains hooked up, so it shouldn't break anything. NV20 will probably break if load_context() works. No inital context values are filled in, so when the first channel is created PGRAPH will probably end up having its state zeroed. Some setup from nv20_graph_init() will probably need to be moved to the per-channel context setup. --- shared-core/nv10_graph.c | 17 ++++++++++++++++- 1 file changed, 16 insertions(+), 1 deletion(-) (limited to 'shared-core/nv10_graph.c') diff --git a/shared-core/nv10_graph.c b/shared-core/nv10_graph.c index fb189709..d1fe0a54 100644 --- a/shared-core/nv10_graph.c +++ b/shared-core/nv10_graph.c @@ -611,7 +611,7 @@ void nouveau_nv10_context_switch(drm_device_t *dev) if (offset > 0) \ fifo->pgraph_ctx[offset] = val; \ } while (0) -int nv10_graph_context_create(drm_device_t *dev, int channel) { +int nv10_graph_create_context(drm_device_t *dev, int channel) { drm_nouveau_private_t *dev_priv = dev->dev_private; struct nouveau_fifo *fifo = &dev_priv->fifos[channel]; uint32_t tmp, vramsz; @@ -663,6 +663,21 @@ int nv10_graph_context_create(drm_device_t *dev, int channel) { return 0; } +void nv10_graph_destroy_context(drm_device_t *dev, int channel) +{ +} + +int nv10_graph_load_context(drm_device_t *dev, int channel) +{ + DRM_ERROR("stub!\n"); + return 0; +} + +int nv10_graph_save_context(drm_device_t *dev, int channel) +{ + DRM_ERROR("stub!\n"); + return 0; +} int nv10_graph_init(drm_device_t *dev) { drm_nouveau_private_t *dev_priv = dev->dev_private; -- cgit v1.2.3 From c806bba4665bb369168ee0b453fa28e2e0bf2a5d Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Thu, 5 Jul 2007 00:12:33 +1000 Subject: nouveau/nv50: Initial channel/object support Should be OK on G84 for a single channel, multiple channels *almost* work.
