Marcin Kościelnicki 304424e17d drm/nv50: Improve PGRAPH interrupt handling. 
This makes nouveau recognise and report more kinds of PGRAPH errors, as
well as prevent GPU lockups resulting from some of them.

Lots of guesswork was involved and some part of this is probably
incorrect. Some potential-lockuop situations are handled by just
resetting a whole PGRAPH subunit, which doesn't sound like a "proper"
solution, but seems to work just fine... for now.

/*
* This code deals with PGRAPH contexts on NV50 family cards. Like NV40, it's
* the GPU itself that does context-switching, but it needs a special
* microcode to do it. And it's the driver's task to supply this microcode,
* further known as ctxprog, as well as the initial context values, known
* as ctxvals.
*
* Without ctxprog, you cannot switch contexts. Not even in software, since
* the majority of context [xfer strands] isn't accessible directly. You're
* stuck with a single channel, and you also suffer all the problems resulting
* from missing ctxvals, since you cannot load them.
*
* Without ctxvals, you're stuck with PGRAPH's default context. It's enough to
* run 2d operations, but trying to utilise 3d or CUDA will just lock you up,
* since you don't have... some sort of needed setup.
*
* Nouveau will just disable acceleration if not given ctxprog + ctxvals, since
* it's too much hassle to handle no-ctxprog as a special case.
*/
/*
* How ctxprogs work.
*
* The ctxprog is written in its own kind of microcode, with very small and
* crappy set of available commands. You upload it to a small [512 insns]
* area of memory on PGRAPH, and it'll be run when PFIFO wants PGRAPH to
* switch channel. or when the driver explicitely requests it. Stuff visible
* to ctxprog consists of: PGRAPH MMIO registers, PGRAPH context strands,
* the per-channel context save area in VRAM [known as ctxvals or grctx],
* 4 flags registers, a scratch register, two grctx pointers, plus many
* random poorly-understood details.
*
* When ctxprog runs, it's supposed to check what operations are asked of it,
* save old context if requested, optionally reset PGRAPH and switch to the
* new channel, and load the new context. Context consists of three major
* parts: subset of MMIO registers and two "xfer areas".

/*
* xfer areas. These are a pain.
*
* There are 2 xfer areas: the first one is big and contains all sorts of
* stuff, the second is small and contains some per-TP context.
*
* Each area is split into 8 "strands". The areas, when saved to grctx,
* are made of 8-word blocks. Each block contains a single word from
* each strand. The strands are independent of each other, their
* addresses are unrelated to each other, and data in them is closely
* packed together. The strand layout varies a bit between cards: here
* and there, a single word is thrown out in the middle and the whole
* strand is offset by a bit from corresponding one on another chipset.
* For this reason, addresses of stuff in strands are almost useless.
* Knowing sequence of stuff and size of gaps between them is much more
* useful, and that's how we build the strands in our generator.
*
* NVA0 takes this mess to a whole new level by cutting the old strands
* into a few dozen pieces [known as genes], rearranging them randomly,
* and putting them back together to make new strands. Hopefully these
* genes correspond more or less directly to the same PGRAPH subunits
* as in 400040 register.
*
* The most common value in default context is 0, and when the genes
* are separated by 0's, gene bounduaries are quite speculative...
* some of them can be clearly deduced, others can be guessed, and yet
* others won't be resolved without figuring out the real meaning of
* given ctxval. For the same reason, ending point of each strand
* is unknown. Except for strand 0, which is the longest strand and
* its end corresponds to end of the whole xfer.
*
* An unsolved mystery is the seek instruction: it takes an argument
* in bits 8-18, and that argument is clearly the place in strands to
* seek to... but the offsets don't seem to correspond to offsets as
* seen in grctx. Perhaps there's another, real, not randomly-changing
* addressing in strands, and the xfer insn just happens to skip over
* the unused bits? NV10-NV30 PIPE comes to mind...
*
* As far as I know, there's no way to access the xfer areas directly
* without the help of ctxprog.
