Subject: [PATCH 09/11] ACPICA: Tables: Allow FADT to be customized with virtual address
Date: Wed, 30 Nov 2016 15:21:49 +0800 [thread overview]
Message-ID: <b08910f2bb009b36eee1b5a86c8c265a86c153b2.1480490191.git.lv.zheng@intel.com> (raw)
In-Reply-To: <cover.1480490191.git.lv.zheng@intel.com>
ACPICA commit d98de9ca14891130efc5dcdc871b97eb27b4b0f5
FADT parsing code requires FADT to be installed as
ACPI_TABLE_ORIGIN_INTERNAL_PHYSICAL, using new
acpi_tb_get_table()/acpi_tb_put_table(), other address types can also be allowed,
thus facilitates FADT customization with virtual address. Lv Zheng.
