From 163f8526123ffa38783fc911b5f7a19debce7f73 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Mon, 2 Jul 2007 19:31:18 +1000 Subject: nouveau: rewrite gpu object code Allows multiple references to a single object, needed to support PCI(E)GART scatter-gather DMA objects which would quickly fill PRAMIN if each channel had its own. Handle per-channel private instmem areas. This is needed to support NV50, but might be something we want to do on earlier chipsets at some point? Everything that touches PRAMIN is a GPU object. --- shared-core/nv10_fifo.c | 33 ++++++++++++++++++--------------- 1 file changed, 18 insertions(+), 15 deletions(-) (limited to 'shared-core/nv10_fifo.c') diff --git a/shared-core/nv10_fifo.c b/shared-core/nv10_fifo.c index b84971de..07ec4635 100644 --- a/shared-core/nv10_fifo.c +++ b/shared-core/nv10_fifo.c @@ -28,8 +28,11 @@ #include "drm.h" #include "nouveau_drv.h" -#define RAMFC_WR(offset, val) NV_WI32(fifoctx + NV10_RAMFC_##offset, (val)) -#define RAMFC_RD(offset) NV_RI32(fifoctx + NV10_RAMFC_##offset) + +#define RAMFC_WR(offset,val) INSTANCE_WR(chan->ramfc->gpuobj, \ + NV10_RAMFC_##offset/4, (val)) +#define RAMFC_RD(offset) INSTANCE_RD(chan->ramfc->gpuobj, \ + NV10_RAMFC_##offset/4) #define NV10_RAMFC(c) (dev_priv->ramfc_offset + NV10_RAMFC__SIZE) #define NV10_RAMFC__SIZE ((dev_priv->chipset) >= 0x17 ? 64 : 32) @@ -38,20 +41,21 @@ nv10_fifo_create_context(drm_device_t *dev, int channel) { drm_nouveau_private_t *dev_priv = dev->dev_private; struct nouveau_fifo *chan = &dev_priv->fifos[channel]; - uint32_t fifoctx = NV10_RAMFC(channel), pushbuf; - int i; - - pushbuf = nouveau_chip_instance_get(dev, chan->cmdbuf_obj->instance); + int ret; - for (i=0; iramfc))) + return ret; /* Fill entries that are seen filled in dumps of nvidia driver just * after channel's is put into DMA mode */ RAMFC_WR(DMA_PUT , chan->pushbuf_base); RAMFC_WR(DMA_GET , chan->pushbuf_base); - RAMFC_WR(DMA_INSTANCE , pushbuf); + RAMFC_WR(DMA_INSTANCE , chan->pushbuf->instance >> 4); RAMFC_WR(DMA_FETCH , NV_PFIFO_CACHE1_DMA_FETCH_TRIG_128_BYTES | NV_PFIFO_CACHE1_DMA_FETCH_SIZE_128_BYTES | NV_PFIFO_CACHE1_DMA_FETCH_MAX_REQS_8 | @@ -67,18 +71,17 @@ void nv10_fifo_destroy_context(drm_device_t *dev, int channel) { drm_nouveau_private_t *dev_priv = dev->dev_private; - uint32_t fifoctx = NV10_RAMFC(channel); - int i; + struct nouveau_fifo *chan = &dev_priv->fifos[channel]; - for (i=0; iramfc) + nouveau_gpuobj_ref_del(dev, &chan->ramfc); } int nv10_fifo_load_context(drm_device_t *dev, int channel) { drm_nouveau_private_t *dev_priv = dev->dev_private; - uint32_t fifoctx = NV10_RAMFC(channel); + struct nouveau_fifo *chan = &dev_priv->fifos[channel]; uint32_t tmp; NV_WRITE(NV03_PFIFO_CACHE1_PUSH1 , 0x00000100 | channel); @@ -120,7 +123,7 @@ int nv10_fifo_save_context(drm_device_t *dev, int channel) { drm_nouveau_private_t *dev_priv = dev->dev_private; - uint32_t fifoctx = NV10_RAMFC(channel); + struct nouveau_fifo *chan = &dev_priv->fifos[channel]; uint32_t tmp; RAMFC_WR(DMA_PUT , NV_READ(NV04_PFIFO_CACHE1_DMA_PUT)); -- cgit v1.2.3
