Subject: [RFC 01/12] arm64: sysreg: Add definitions for FEAT_TLBID
Date: Thu, 1 Oct 2026 12:06:44 +0100 [thread overview]
Message-ID: <20261001110655.461473-2-kristina.martsenko@arm.com> (raw)
In-Reply-To: <20261001110655.461473-1-kristina.martsenko@arm.com>
Describe new system registers and fields added by FEAT_TLBID, so that
later patches can use them. This is based on the latest system register
specifications (version 2026-09, see Link).
The size and number of fields in VTLBID* registers is determined by
information in other registers at runtime, so can't be described
statically here.
