Subject: [PATCH AUTOSEL 5.4 06/10] perf/x86/intel/pt: Fix mask of num_address_ranges
Date: Mon, 30 Aug 2021 08:00:13 -0400 [thread overview]
Message-ID: <20210830120018.1017841-6-sashal@kernel.org> (raw)
In-Reply-To: <20210830120018.1017841-1-sashal@kernel.org>
From: Xiaoyao Li <xiaoyao.li@intel.com>
[ Upstream commit c53c6b7409f4cd9e542991b53d597fbe2751d7db ]
Per SDM, bit 2:0 of CPUID(0x14,1).EAX[2:0] reports the number of
configurable address ranges for filtering, not bit 1:0.
