Commit Message

Sujuan Chen Nov. 21, 2022, 11:37 a.m. UTC
The current WED only supports 256 wcid, whereas mt7986 can support up to 512 entries,
so firmware provides a rule to get sta_info by DA when wcid is set to 0x3ff by txd.
Also, WED provides a register to overwrite txd wcid, that is, wcid[9:8] can
be overwritten by 0x3 and wcid[7:0] is set to 0xff by host driver.

However, firmware is unable to get sta_info from DA as DA != RA for 4addr cases,
so firmware and wifi host driver both use wcid (256 - 271) and (768 ~ 783)
for sync up to get correct sta_info

Hi Sujuan,

I took just a brief look at the patch, but I think you can significantly
reduce the patch size doing something like:

int __mt76_wcid_alloc(u32 *mask, int size, u8 flag)
{
	...
}

static inline int mt76_wcid_alloc(u32 *mask, int size)
{
	return __mt76_wcid_alloc(, 0);
}

can you please honor mt7915_mcu_wa_cmd() returned value?

I think it easier to understand the code if you run the code below just if wed
is active, right?

		if (!mtk_wed_device_active())
			break;

mtk_wed_device_active() need mt76_dev to get wed.
!mtk_wed_device_active() is include in MT76_WED_DISABLED.
Would it be better to run if (!mtk_wed_device_active())?

Actually, the logic is a bit more complicated.
Using only mtk_wed_device_active() cannot cover all cases.
wcid(256~271) is special using for WDS when WED is enabled.
and wcid(256~271) will be used for normal sta when wcid(exclude
256~271) is run out.

I will change MT76_WED_DISABLED to MT76_WED_DEFAULT which includes
below situation:
	(wed is disabled || beacon wcid(0))

is it ok?

Hi Lore,

ack, thanks. I will do it in v2.

Actually, it's a bit more complicated.
Using only mtk_wed_device_active() cannot cover all cases.
for wed on(MT76_WED_ACTIVE), We should use wcid outside of (256~271).
and when wed on but sta exceeds (512-16), we should use wcid(256~271).
for wed on and sta is wds case(MT76_WED_WDS_ACTIVE), we
use wcid(256~271) .

mtk_wed_device_active() need mt76_dev to get wed.
!mtk_wed_device_active() is include in MT76_WED_DISABLED.
Would it be better to run if (!mtk_wed_device_active())?

Actually, the logic is a bit more complicated.
Using only mtk_wed_device_active() cannot cover all cases.
wcid(256~271) is special using for WDS when WED is enabled.
and wcid(256~271) will be used for normal sta when wcid(exclude
256~271) is run out.

I will change MT76_WED_DISABLED to MT76_WED_DEFAULT which includes
below situation:
	(wed is disabled || beacon wcid(0))

is it ok?
