25/* NVIDIA context programs handle a number of other conditions which are
26 * not implemented in our versions. It's not clear why NVIDIA context
27 * programs have this code, nor whether it's strictly necessary for
28 * correct operation. We'll implement additional handling if/when we
29 * discover it's necessary.
30 *
31 * - On context save, NVIDIA set 0x400314 bit 0 to 1 if the "3D state"
32 * flag is set, this gets saved into the context.
33 * - On context save, the context program for all cards load nsource
34 * into a flag register and check for ILLEGAL_MTHD. If it's set,
35 * opcode 0x60000d is called before resuming normal operation.
36 * - Some context programs check more conditions than the above. NV44
37 * checks: ((nsource & 0x0857) || (0x400718 & 0x0100) || (intr & 0x0001))
38 * and calls 0x60000d before resuming normal operation.
39 * - At the very beginning of NVIDIA's context programs, flag 9 is checked
40 * and if true 0x800001 is called with count=0, pos=0, the flag is cleared
41 * and then the ctxprog is aborted. It looks like a complicated NOP,
42 * its purpose is unknown.
43 * - In the section of code that loads the per-vs state, NVIDIA check
44 * flag 10. If it's set, they only transfer the small 0x300 byte block
45 * of state + the state for a single vs as opposed to the state for
46 * all vs units. It doesn't seem likely that it'll occur in normal
47 * operation, especially seeing as it appears NVIDIA may have screwed
48 * up the ctxprogs for some cards and have an invalid instruction
49 * rather than a cp_lsr(ctx, dwords_for_1_vs_unit) instruction.
50 * - There's a number of places where context offset 0 (where we place
51 * the PRAMIN offset of the context) is loaded into either 0x408000,
52 * 0x408004 or 0x408008. Not sure what's up there either.
53 * - The ctxprogs for some cards save 0x400a00 again during the cleanup
54 * path for auto-loadctx.
