It's clearly your decision, but you're probably better off supporting
the modern channel context APIs, even if (at this time) you only support
a single channel.

The settings and methods here that apply to the "whole hardware" are
mostly obsolete as far as mac80211 is concerned.

Now, I also don't recommend you change that now, and it's clearly not a
requirement for an in-tree driver, but something to think about.

That's a bit weird, port is always 0. But I guess it's some kind of
preparation for future multi-interface changes (and then you probably
want the channel contexts too?)

I'm not convinced that warrants an "info" level trace, but YMMV.

dito

Also, here, I'd consider using sta-state API, it tells you more. Here
it's even less important though since from mac80211's POV it's exactly
the same (it only ever calls sta_state) but the driver with
sta_add/sta_remove gets a filtered view thereof.

I note you don't handle any kinds of firmware restart scenarios here. I
guess eventually you'd want to?

> +static void rtw_watch_dog_work(struct work_struct *work)

Hm, is that really a "watchdog" in the usual sense?

It seems more like some sort of "periodic work" like the LPS stuff
below, or whatever the PHY dynamic thing is - but not a "watchdog" in
the sense of checking that things are still OK?

Anyway, just a nit about semantics.

(I was looking for FW restart handling here or so)

Maybe I'm misreading the code, but does this every do anything? It
looked like you only get here after the callback.

Consider using at least round_jiffies_relative() - this is expensive
from a power consumption POV already and doesn't look like it needs
perfect timing.

same here?

It sort of looked like you don't even need the completion, but I may not
be understanding the full flow.

Typically the flow would be

probe -> load firmware -> firmware callback -> continue work

but I haven't checked in detail if it's different here. If it is though,
why should it be? You can't really do anything without firmware?

> +++ b/drivers/net/wireless/realtek/rtw88/main.h

This file is a bit confusing. On the one hand, you have things like:


> +#define RTW_WATCH_DOG_DELAY_TIME	round_jiffies_relative(HZ * 2)

(ohh. you did use round_jiffies_relative!)

This which are very clearly driver specific.

On the other hand you have:

And lots of other things like that which look like some kind of device
API (firmware, hardware, OTP, ...)

IMHO it'd be cleaner to separate that into different files.

Again, for example:

> +enum rtw_regulatory_domains {
> +	RTW_REGD_FCC	= 0,
> +	RTW_REGD_MKK	= 1,
> +	RTW_REGD_ETSI	= 2,

Must be hardware API otherwise you wouldn't really care about the exact
values, I guess?

> +

> +};

Where this is clearly pure driver but everything is completely
intermingled.

It's not a huge problem, but ...

Again, clearly something with the device, otherwise you wouldn't go to
the effort of doing correct-endian-bitfields :-)

(Which I wouldn't really recommend anyway ... but that's another story)

Why not make those inlines?

This is kinda incomplete, perhaps we should export ieee80211_get_bssid()
instead?

Anyway, none of that really seems like blocking issues.
