Subject: [PATCH v2 3/3] docs/system/arm/emulation.rst: Report FEAT_GTG support
Date: Mon,  3 Oct 2022 17:23:15 +0100	[thread overview]
Message-ID: <20221003162315.2833797-4-peter.maydell@linaro.org> (raw)
In-Reply-To: <20221003162315.2833797-1-peter.maydell@linaro.org>

FEAT_GTG is a change tho the ID register ID_AA64MMFR0_EL1 so that it
can report a different set of supported granule (page) sizes for
stage 1 and stage 2 translation tables.  As of commit c20281b2a5048
we already report the granule sizes that way for '-cpu max', and now
we also correctly make attempts to use unimplemented granule sizes
fail, so we can report the support of the feature in the
documentation.
