Subject: [PATCH v3 2/9] mhi: pci-generic: Increase number of hardware events
Date: Thu, 26 Nov 2020 16:29:00 +0100 [thread overview]
Message-ID: <1606404547-10737-3-git-send-email-loic.poulain@linaro.org> (raw)
In-Reply-To: <1606404547-10737-1-git-send-email-loic.poulain@linaro.org>
If the IPA (IP hardware accelerator) is starved of event ring elements,
the modem is crashing (SDX55). That can be prevented by setting a
larger number of events (i.e 2 x number of channel ring elements).
Tested with FN980m module.
