2007-08-15nouveau: Allow GART notifiers when using sgdma code.Ben Skeggs
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.

2007-07-12nouveau: separate region_offset into map_handle and offset.Ben Skeggs
2007-07-09nouveau: Allocate mappable VRAM for notifiers..Ben Skeggs
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.
