Subject: [PATCH v3 10/30] baseband/acc100: fix clearing PF IR outside handler
Date: Tue, 11 Oct 2022 19:53:26 -0700 [thread overview]
Message-ID: <20221012025346.204394-11-hernan.vargas@intel.com> (raw)
In-Reply-To: <20221012025346.204394-1-hernan.vargas@intel.com>
Clearing of PF info ring outside of handler may cause interrupt to be
missed.
A condition in the ACC100 PMD implementation may cause an interrupt
functional handler call to be missed due to related bit being cleared
when checking PF info ring status.
Fixes: 06531464151 ("baseband/acc100: support interrupt")
