Subject: [PATCH 08/20] common/cnxk: use SSO time counter threshold for IRQ
Date: Mon, 7 Feb 2022 12:59:20 +0530	[thread overview]
Message-ID: <20220207072932.22409-8-ndabilpuram@marvell.com> (raw)
In-Reply-To: <20220207072932.22409-1-ndabilpuram@marvell.com>

Enable time counter based threshold for raising SSO
EXE_INT instead of IAQ threshold.
