Subject: Re: [PATCH net-next v6 1/3] dpll: zl3073x: scale poll interval proportionally to timeout
Date: Tue, 11 Aug 2026 14:20:49 +0200	[thread overview]
Message-ID: <86c957ed-0083-4aaa-a5b5-d744d8c604af@redhat.com> (raw)
In-Reply-To: <20260809182340.1081610-2-ivecera@redhat.com>

Sashiko findings with comments:

 > Will this introduce a latency regression for fast bulk hardware
 > operations? [...] zl3073x_flash_download() loops over data [...]
 > This multiplies the total firmware flashing time

Firmware flash operations were tested with no observable regression.
Testing showed that the existing callers typically completed in low
hundreds of sleep cycles with the fixed 10 us interval. With the
scaled interval, the cycle count dropped to single digits — the
reduced iteration count compensates for the longer per-iteration
sleep.

Thanks,
Ivan
