Subject: [PATCH v3 0/4] ACPI / osl: Cleans up acpi_get_table_with_size()/early_acpi_os_unmap_memory()
Date: Wed, 14 Dec 2016 15:04:13 +0800 [thread overview]
Message-ID: <cover.1481698041.git.lv.zheng@intel.com> (raw)
In-Reply-To: <cover.1480490191.git.lv.zheng@intel.com>
acpi_get_table_with_size() is invented to be a replacement of
acpi_get_table() during the early stage so that the early mapped pointer
will not be stored in ACPICA core (acpi_get_table() forces to do so) and
thus the late stage acpi_get_table() won't return a wrong stored pointer.
Since there is early_acpi_os_unmap_memory() required to be invoked as a
reversal of acpi_get_table_with_size(), ACPICA can provide acpi_put_table()
to achieve the same purpose. As long as all early stage acpi_get_table()
calls are paired by early stage acpi_put_table() calls, mappings should be
released before entering the late stage. And the late stage
acpi_get_table() calls will map the table using a late stage ioremap
mechanism.
This patchset cleans up the old APIs and reduces divergences between Linux
and ACPICA upstream.
Lv Zheng (4):
ACPICA: Tables: Back port acpi_get_table_with_size() and
early_acpi_os_unmap_memory() from Linux kernel
ACPICA: Tables: Allow FADT to be customized with virtual address
ACPI / osl: Remove
acpi_get_table_with_size()/early_acpi_os_unmap_memory() users
ACPI / osl: Remove deprecated
acpi_get_table_with_size()/early_acpi_os_unmap_memory()
