Subject: [edk2-devel] [PATCH edk2-platforms v6 5/6] SbsaQemu: introduce helper in PPTT generation
Date: Wed, 07 Aug 2024 13:34:43 +0200 [thread overview]
Message-ID: <20240807-acpi65-v6-5-fc426e4abfe2@linaro.org> (raw)
In-Reply-To: <20240807-acpi65-v6-0-fc426e4abfe2@linaro.org>
Function AddPpttTable() adding PPTT got too long. This change moves part
of it into helper function AddCoresToPpttTable() which takes care of
generating entries for Core and below (Cache, Thread).
