Subject: [RESEND PATCH v2 3/3] Fix IIO event constraints for Snowridge
Date: Mon, 15 Nov 2021 12:03:34 +0300 [thread overview]
Message-ID: <20211115090334.3789-4-alexander.antonov@linux.intel.com> (raw)
In-Reply-To: <20211115090334.3789-1-alexander.antonov@linux.intel.com>
From: Alexander Antonov <alexander.antonov@linux.intel.com>
According to the latest uncore document, DATA_REQ_OF_CPU (0x83),
DATA_REQ_BY_CPU (0xc0) and COMP_BUF_OCCUPANCY (0xd5) events have
constraints. Add uncore IIO constraints for Snowridge.
Fixes: 210cc5f9db7a ("perf/x86/intel/uncore: Add uncore support for Snow Ridge server")
