/*
* 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.
