Subject: [PATCH v3 41/60] arm64/mm: Add FEAT_LPA2 specific TCR_EL1.DS field
Date: Tue, 7 Mar 2023 15:05:03 +0100 [thread overview]
Message-ID: <20230307140522.2311461-42-ardb@kernel.org> (raw)
In-Reply-To: <20230307140522.2311461-1-ardb@kernel.org>
From: Anshuman Khandual <anshuman.khandual@arm.com>
As per ARM ARM (0487G.A) TCR_EL1.DS fields controls whether 52 bit input
and output address get supported on 4K and 16K page size configuration,
when FEAT_LPA2 is known to have been implemented. This adds TCR_DS field
definition which would be used when FEAT_LPA2 gets enabled.
