I want to update the VP9 bilin load, just like you did with VP8, but it
seems like this patch（[PATCH v2 1/5] lavc/vp9dsp: R-V V mc avg） doesn't
merge the current updates here but merges the previous version instead, so
the subsequent patches will have conflicts.

Unfortunately I only test to obtain benchmarks and basic correctness. I

Do macros definition also need a comma? I noticed that many of my old code
and SiFive's code don't have a comma

Is it necessary here? Many macros in the C file are copied from MIPS, where
it is called ff_avg4_msa. Here, it has been simply changed to ff_avg4_rvv.

To obtain test results, need to comment out the if (w == h) in
tests/checkasm/vvc_mc.c.
Because vset needs to be used in the loop, I manually wrote a cumbersome
vset macro.

Using this will give output `if (bpp == 8 && (flags & AV_CPU_FLAG_RVI)) {`
Did you comment out the MISALIGNED flag check but not add RVI, resulting in
no output?

In banana_f3, further reducing the value of mf resulted in another
performance improvement. I think in the end we might need to use different

If the full register name is passed here, some require four parameters,

It might be a bit inconvenient to find the patches related to vp8, vp9 that
were sent earlier. Here, I've placed them in a zip file in this reply

The order of some instructions appears imperfect because, when len==32, the
registers for operations like hv can only just suffice, making it difficult
to adjust.
It's possible to create a separate function for len<32, but it likely won't
have a significant impact, so this hasn't been done yet.

Alright, using m8, but for now don't add code to address dependencies in

larly, you can use \restore as a truth value directly: `.if \restore`.
Okay
FWIW, it seems that you could just as well include func/endfunc inside the
macros.
Do you mean to generate func/endfunc using macros?
