Subject: [PATCH 5.4 13/37] perf/x86/intel/pt: Fix mask of num_address_ranges
Date: Fri, 10 Sep 2021 14:30:16 +0200 [thread overview]
Message-ID: <20210910122917.613045427@linuxfoundation.org> (raw)
In-Reply-To: <20210910122917.149278545@linuxfoundation.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.
