We'll implement additional handling if/when we + * discover it's necessary. + * + * - On context save, NVIDIA set 0x400314 bit 0 to 1 if the "3D state" + * flag is set, this gets saved into the context. + * - On context save, the context program for all cards load nsource + * into a flag register and check for ILLEGAL_MTHD. If it's set, + * opcode 0x60000d is called before resuming normal operation. + * - Some context programs check more conditions than the above. NV44 + * checks: ((nsource & 0x0857) || (0x400718 & 0x0100) || (intr & 0x0001)) + * and calls 0x60000d before resuming normal operation. + * - At the very beginning of NVIDIA's context programs, flag 9 is checked + * and if true 0x800001 is called with count=0, pos=0, the flag is cleared + * and then the ctxprog is aborted. It looks like a complicated NOP, + * its purpose is unknown. + * - In the section of code that loads the per-vs state, NVIDIA check + * flag 10.
