Subject: Bottom halves being disabled
Date: Tue, 24 Aug 2004 05:09:29 -0700 (PDT) [thread overview]
Message-ID: <20040824120929.1377.qmail@web52204.mail.yahoo.com> (raw)
Hi All,
In the NOR driver code, the spin locks are acquired
everywhere with bottom halves disabled using the
spin_lock_bh() API. My doubt is why are the bottom
halves disabled? (Doesn't that add to the real time
latency on the system!)
Hoping someone would clear the doubt
Ed
