Subject: flush_icache_range in the sticore driver
Date: Tue, 5 Jul 2022 18:46:23 +0200 [thread overview]
Message-ID: <20220705164623.GA14566@lst.de> (raw)
Hi all,
flush_icache_range is supposed to flush the instruction cache, which is
something no driver should be doing. It was added in commit 03b18f1b2afe
("[PARISC] Clean up sti_flush") but the explanation in there looks odd.
Can someone shed a light what flushes this tries to flush and why it
can't be done behind a proper API?
