/* NVIDIA context programs handle a number of other conditions which are
|
|
* not implemented in our versions. It's not clear why NVIDIA context
|
|
* programs have this code, nor whether it's strictly necessary for
|
|
* correct operation. 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. If it's set, they only transfer the small 0x300 byte block
|
|
* of state + the state for a single vs as opposed to the state for
|
|
* all vs units. It doesn't seem likely that it'll occur in normal
|
|
* operation, especially seeing as it appears NVIDIA may have screwed
|
|
* up the ctxprogs for some cards and have an invalid instruction
|
|
* rather than a cp_lsr(ctx, dwords_for_1_vs_unit) instruction.
|
|
* - There's a number of places where context offset 0 (where we place
|
|
* the PRAMIN offset of the context) is loaded into either 0x408000,
|
|
* 0x408004 or 0x408008. Not sure what's up there either.
|
|
* - The ctxprogs for some cards save 0x400a00 again during the cleanup
|
|
* path for auto-loadctx.
