2008-06-23nv50: use same dma object for fb/tt accessBen Skeggs
We depend on the VM fully now for memory protection, separate DMA objects for VRAM and GART are unneccesary. However, until the next interface break (soon) a client can't depend on the objects being the same and must still call NV_OBJ_SET_DMA_* methods appropriately.
2008-06-23nouveau: allocate drm-use vram buffers from end of vram.Ben Skeggs
This avoids seeing garbage from engine setup etc before X gets around to pointing the CRTCs at a new scanout buffer. Not actually a noticable problem before G80 as PRAMIN is forced to the end of VRAM by the hardware already.
2008-03-13nv50: force channel vram access through vmBen Skeggs
If we ever want to be able to use the 3D engine we have no choice. It appears that the tiling setup (required for 3D on G8x) is in the page tables. The immediate benefit of this change however is that it's now not possible for a client to use the GPU to render over the top of important engine setup tables, which also live in VRAM. G8x VRAM size is limited to 512MiB at the moment, as we use a 1-1 mapping of real vram pages to their offset within the start of a channel's VRAM DMA object and only populate a single PDE for VRAM use.

2007-08-06nouveau: Various internal and external API changesBen Skeggs
1. DRM_NOUVEAU_GPUOBJ_FREE Used to free GPU objects. The obvious usage case is for Gr objects, but notifiers can also be destroyed in the same way. GPU objects gain a destructor method and private data fields with this change, so other specialised cases (like notifiers) can be implemented on top of gpuobjs. 2. DRM_NOUVEAU_CHANNEL_FREE 3. DRM_NOUVEAU_CARD_INIT Ideally we'd do init during module load, but this isn't currently possible. Doing init during firstopen() is bad as X has a love of opening/closing the DRM many times during startup. Once the modesetting-101 branch is merged this can go away. IRQs are enabled in nouveau_card_init() now, rather than having the X server call drmCtlInstHandler(). We'll need this for when we give the kernel module its own channel. 4. DRM_NOUVEAU_GETPARAM Add CHIPSET_ID value, which will return the chipset id derived from NV_PMC_BOOT_0. 4. Use list_* in a few places, rather than home-brewed stuff.

2007-07-20Replace DRM_IOCTL_ARGS with (dev, data, file_priv) and remove DRM_DEVICE.Eric Anholt
The data is now in kernel space, copied in/out as appropriate according to the This results in DRM_COPY_{TO,FROM}_USER going away, and error paths to deal with those failures. This also means that XFree86 4.2.0 support for i810 DRM is lost.
2007-07-20Replace filp in ioctl arguments with drm_file *file_priv.Eric Anholt
As a fallout, replace filp storage with file_priv storage for "unique identifier of a client" all over the DRM. There is a 1:1 mapping, so this should be a noop. This could be a minor performance improvement, as everything on Linux dereferenced filp to get file_priv anyway, while only the mmap ioctls went the other direction.
2007-07-20Remove DRM_ERR OS macro.Eric Anholt
This was used to make all ioctl handlers return -errno on linux and errno on *BSD. Instead, just return -errno in shared code, and flip sign on return from shared code to *BSD code.
2007-07-17nouveau: G8x PCIEGARTBen Skeggs
Actually a NV04-NV50 ttm backend for both PCI and PCIEGART, but PCIGART support for G8X using the current mm has been hacked on top of it.

2007-07-09nouveau/nv50: Initial channel/object supportBen Skeggs
Should be OK on G84 for a single channel, multiple channels *almost* work. Untested on G80.
2007-07-09nouveau: rewrite gpu object codeBen Skeggs
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.
2007-06-28nouveau: never touch PRAMIN with NV_WRITE, cleanup RAMHT code a bitBen Skeggs
2007-06-28nouveau: Nuke DMA_OBJECT_INIT ioctl (bumps interface to 0.0.7)Ben Skeggs
For various reasons, this ioctl was a bad idea. At channel creation we now automatically create DMA objects covering available VRAM and GART memory, where the client used to do this themselves. However, there is still a need to be able to create DMA objects pointing at specific areas of memory (ie. notifiers). Each channel is now allocated a small amount of memory from which a client can suballocate things (such as notifiers), and have a DMA object created which covers the suballocated area. The NOTIFIER_ALLOC ioctl exposes this functionality.

2007-02-28nouveau: intrusive drm interface changesBen Skeggs
graphics objects: - No longer takes flags/dmaobj parameters, requires some major changes to the ddx to setup the object through the FIFO. This change is likely to cause breakages on some cards (tested on NV05,NV28,NV35, NV40 and NV4E). dma objects: - now takes a "class" parameter, not really used yet but we may need it at some point. - parameters are checked, so clients can't randomly create DMA objects pointing at whatever they feel like. misc: - Added FB_SIZE/AGP_SIZE getparams - Read PFIFO_INTR in PFIFO irq handler, not PMC_INTR - Dump PGRAPH trap info on PGRAPH_INTR_NOTIFY if NSOURCE isn't NOTIFICATION_PENDING.

2006-11-18Check some return vals, fixes a couple of oopses.Ben Skeggs
2006-11-14Restructure initialisation a bit.Ben Skeggs
- Do important card init in firstopen - Give each channel it's own cmdbuf dma object - Move RAMHT config state to the same place as RAMRO/RAMFC - Make sure instance mem for objects is *after* RAM{FC,HT,RO}
2006-11-06Leave the bottom 64kb of RAMIN untouched.Ben Skeggs
The binary driver will screw up either it's init or shutdown, leaving the screen(s) in an unusable state without this. Something important in there?

2006-10-17NV40: *Now* fifo ctx switching works for me..Ben Skeggs
Ok, I lied before.. it was a fluke it worked and required magic to repeat it.. It actually helps to fill in RAMFC entries in the correct place. The code also clears RAMIN entirely instead of just the hash-table.

2006-09-07Fix second start of X server without module reload beforehand, and a couple ↵Ben Skeggs
of other fixes. - Mark the correct RAMIN slots as free (oops) - Remove a VRAM alloc that shouldn't have been there (oops) - Move HT init out of firstopen() and into dma_init() - Setup PFIFO_RAM{HT,FC,RO} in pfifo_init()
2006-09-02Use DMA_IN_MEMORY for DMA objects. This is needed for a DDX change that willBen Skeggs
be committed soon after this. Without the change, MEMFORMAT_DMA_OUT appears to have no effect.
