2009-03-06drm/nouveau: make portion of vram as reserved for PRAMIN on all chipsetsBen Skeggs
NV04 was completely busted. Push buffers were getting allocated at the end of VRAM, overwriting PRAMIN. So, it turns out PRAMIN is in VRAM on all chips. Question answered!
2009-03-02drm: drop Linux < 2.6.19 supportPekka Paalanen
This also means dropping the DRM_ODD_MM_COMPAT case. Signed-off-by: Pekka Paalanen <pq@iki.fi>

Fixes nouveau_ioctl_mem_free Oops
2009-02-04nouveau: bring in new mm api definitions, without the actual mm codeBen Skeggs
Use of the new bits is guarded with a mm_enabled=0 hardcode.
2008-12-10Revert "Merge branch 'modesetting-gem'"Jesse Barnes
This reverts commit 6656db10551bbb8770dd945b6d81d5138521f208. We really just want the libdrm and ioctl bits, not all the driver stuff.

2008-07-18nv50: 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.

2008-06-25nouveau: 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.

Also, power cycle PGRAPH when resetting AGP -- it seems to fix problems encountered by p0g on nv25

this adds something to say the kernel initialised the memory region not the userspace. and blocks userspace from deallocating kernel areas

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.
