Subject: [PATCH v3 1/8] megaraid_sas: For SRIOV enabled firmware, ensure VF driver waits for 30secs before reset
Date: Fri, 21 Oct 2016 06:33:29 -0700	[thread overview]
Message-ID: <1477056816-7058-2-git-send-email-kashyap.desai@broadcom.com> (raw)
In-Reply-To: <1477056816-7058-1-git-send-email-kashyap.desai@broadcom.com>

For SRIOV enabled firmware, if there is a OCR(online controller reset)
possibility driver set the convert flag to 1, which is not happening if
there are outstanding commands even after 180 seconds.
As driver does not set convert flag to 1 and still making the OCR to run,
VF(Virtual function) driver is directly writing on to the register
instead of waiting for 30 seconds. Setting convert flag to 1 will cause
VF driver will wait for 30 secs before going for reset.
