Re: [PATCH v3 1/2] Perform additional retries if Doorbell read returns 0

Hi Ranjan,

But for few registers zero may be a valid value and we don’t want those registers to get penalized with 30 read retries where 1/3 reads would have sufficed.

If 0 is a valid register value you'll end up always doing 3 retries before returning. Even if the first register reads were "successful". Peculiar!
