drm/nouveau: Add DRM driver for NVIDIA GPUs
This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA. This driver is a KMS-based driver and requires a compatible nouveau userspace libdrm and nouveau X.org driver. This driver requires firmware files not available in this kernel tree, interested parties can find them via the nouveau project git archive. This driver is reverse engineered, and is in no way supported by nVidia. Support for nearly the complete range of nvidia hw from nv04->g80 (nv50) is available, and the kms driver should support driving nearly all output types (displayport is under development still) along with supporting suspend/resume. This work is all from the upstream nouveau project found at nouveau.freedesktop.org. The original authors list from nouveau git tree is: Anssi Hannula <anssi.hannula@iki.fi> Ben Skeggs <bskeggs@redhat.com> Francisco Jerez <currojerez@riseup.net> Maarten Maathuis <madman2003@gmail.com> Marcin Kościelnicki <koriakin@0x04.net> Matthew Garrett <mjg@redhat.com> Matt Parnell <mparnell@gmail.com> Patrice Mandin <patmandin@gmail.com> Pekka Paalanen <pq@iki.fi> Xavier Chantry <shiningxc@gmail.com> along with project founder Stephane Marchesin <marchesin@icps.u-strasbg.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

1874 * 1) is done by a cunning combination of writes to offsets 0x1c and

1876 * read back correctly. This then affects bits 4-7 of NV_PFB_CFG0

1881 * NV_PFB_CFG0

1884 * and writes to varying locations, often alternating the test pattern
1885 * and 0, doubtless to make sure buffers are filled, residual charges
1886 * on tracks are removed etc.
1887 *

38/* NVidia uses context objects to drive drawing operations.
39
40 Context objects can be selected into 8 subchannels in the FIFO,
41 and then used via DMA command buffers.
42
43 A context object is referenced by a user defined handle (CARD32). The HW
44 looks up graphics objects in a hash table in the instance RAM.
45
46 An entry in the hash table consists of 2 CARD32. The first CARD32 contains
47 the handle, the second one a bitfield, that contains the address of the
48 object in instance RAM.
49
50 The format of the second CARD32 seems to be:
51
52 NV4 to NV30:
53
54 15: 0 instance_addr >> 4
55 17:16 engine (here uses 1 = graphics)
56 28:24 channel id (here uses 0)
57 31 valid (use 1)
58
59 NV40:
60
61 15: 0 instance_addr >> 4 (maybe 19-0)
62 21:20 engine (here uses 1 = graphics)
63 I'm unsure about the other bits, but using 0 seems to work.
64
65 The key into the hash table depends on the object handle and channel id and
66 is given as:

217 * The following is some guesswork on how the TV encoder flicker
218 * filter/rescaler works:
219 *
220 * It seems to use some sort of resampling filter, it is controlled
221 * through the registers at NV_PTV_HFILTER and NV_PTV_VFILTER, they
222 * control the horizontal and vertical stage respectively, there is
223 * also NV_PTV_HFILTER2 the blob fills identically to NV_PTV_HFILTER,
224 * but they seem to do nothing. A rough guess might be that they could
225 * be used to independently control the filtering of each interlaced
226 * field, but I don't know how they are enabled. The whole filtering
227 * process seems to be disabled with bits 26:27 of PTV_200, but we
228 * aren't doing that.
229 *
230 * The layout of both register sets is the same:
231 *
232 * A: [BASE+0x18]...[BASE+0x0] [BASE+0x58]..[BASE+0x40]
233 * B: [BASE+0x34]...[BASE+0x1c] [BASE+0x74]..[BASE+0x5c]
234 *
235 * Each coefficient is stored in bits [31],[15:9] in two's complement
236 * format. They seem to be some kind of weights used in a low-pass
237 * filter. Both A and B coefficients are applied to the 14 nearest
238 * samples on each side (Listed from nearest to furthermost. They
239 * roughly cover 2 framebuffer pixels on each side). They are
240 * probably multiplied with some more hardwired weights before being
241 * used: B-coefficients are applied the same on both sides,
242 * A-coefficients are inverted before being applied to the opposite
243 * side.
244 *
245 * After all the hassle, I got the following formula by empirical
246 * means...
