early_acpi_os_unmap_memory() from Linux kernel
ACPICA commit cac6790954d4d752a083e6122220b8a22febcd07
This patch back ports Linux acpi_get_table_with_size() and
early_acpi_os_unmap_memory() into ACPICA upstream to reduce divergences.
The 2 APIs are used by Linux as table management APIs for long time, it
contains a hidden logic that during the early stage, the mapped tables
should be unmapped before the early stage ends.
During the early stage, tables are handled by the following sequence:
acpi_get_table_with_size();
parse the table
early_acpi_os_unmap_memory();
During the late stage, tables are handled by the following sequence:
acpi_get_table();
parse the table
Linux uses acpi_gbl_permanent_mmap to distinguish the early stage and the
late stage.
The reasoning of introducing acpi_get_table_with_size() is: ACPICA will
remember the early mapped pointer in acpi_get_table() and Linux isn't able to
prevent ACPICA from using the wrong early mapped pointer during the late
stage as there is no API provided from ACPICA to be an inverse of
acpi_get_table() to forget the early mapped pointer.
But how ACPICA can work with the early/late stage requirement? Inside of
ACPICA, tables are ensured to be remained in "INSTALLED" state during the
early stage, and they are carefully not transitioned to "VALIDATED" state
until the late stage. So the same logic is in fact implemented inside of
ACPICA in a different way. The gap is only that the feature is not provided
to the OSPMs in an accessible external API style.
It then is possible to fix the gap by providing an inverse of
acpi_get_table() from ACPICA, so that the two Linux sequences can be
combined:
acpi_get_table();
parse the table
acpi_put_table();
In order to work easier with the current Linux code, acpi_get_table() and
acpi_put_table() is implemented in a usage counting based style:
1. When the usage count of the table is increased from 0 to 1, table is
mapped and .Pointer is set with the mapping address (VALIDATED);
2. When the usage count of the table is decreased from 1 to 0, .Pointer
is unset and the mapping address is unmapped (INVALIDATED).
So that we can deploy the new APIs to Linux with minimal effort by just
invoking acpi_get_table() in acpi_get_table_with_size() and invoking
acpi_put_table() in early_acpi_os_unmap_memory(). Lv Zheng.

ACPICA commit 68af3c3aa238dd8040e846ac6b4827a016434d8d
During early OS boot stage, drivers that have mapped system memory should
unmap it during the same stage. Linux kernel has an error message
indicating the unbalanced early memory mappings.
This patch back ports such error message into ACPICA for the early table
mappings, so that ACPICA development environment is also aware of this OS
specific requirement and thus is able to ensure the consistent quality
locally. Lv Zheng.

ACPICA commit b2294cae776f5a66a7697414b21949d307e6856f
This patch removes unwanted spaces for typedef. This solution doesn't cover
function types.
Note that the linuxize result of this commit is very giant and should have
many conflicts against the current Linux upstream. Thus it is required to
modify the linuxize result of this commit and the commits around it
manually in order to have them merged to the Linux upstream. Since this is
very costy, we should do this only once, and if we can't ensure to do this
only once, we need to revert the Linux code to the wrong indentation result
before merging the linuxize result of this commit. Lv Zheng.

This patch refines ACPI_TABLE_ORIGIN_xxx flags. No functional changes.
The previous commits have introduced the following internal APIs:
1. acpi_tb_acquire_table: Acquire struct acpi_table_header according to
ACPI_TABLE_ORIGIN_xxx flags.
2. acpi_tb_release_table: Release struct acpi_table_header according to
ACPI_TABLE_ORIGIN_xxx flags.
3. acpi_tb_install_table: Make struct acpi_table_desc.Address not NULL according to
ACPI_TABLE_ORIGIN_xxx flags.
4. acpi_tb_uninstall_table: Make struct acpi_table_desc.Address NULL according to
ACPI_TABLE_ORIGIN_xxx flags.
5. acpi_tb_validate_table: Make struct acpi_table_desc.Pointer not NULL according to
ACPI_TABLE_ORIGIN_xxx flags.
6. acpi_tb_invalidate_table: Make struct acpi_table_desc.Pointer NULL according to
ACPI_TABLE_ORIGIN_xxx flags.
It thus detects that the ACPI_TABLE_ORIGIN_UNKNOWN is redundant to
ACPI_TABLE_ORIGIN_OVERRIDE.
The ACPI_TABLE_ORIGIN_xxTERN_VIRTUAL flags are named as VIRTUAL in order
not to confuse with x86 logical address, this patch also renames all
"logical override" into "virtual override".

This patch is mainly a naming cleanup to clarify hidden logics, no
functional changes.
acpi_initialize_tables() is used by Linux to install table addresses for
early boot steps. During this stage, table addresses are mapped by
early_ioremap() mechanism which is different from the runtime IO mappings.
Thus it is not safe for ACPICA to keep mapped pointers in struct acpi_table_desc
structure during this stage.
In order to support this in ACPICA, table states are divided into
1. "INSTALLED" (where struct acpi_table_desc.Pointer is always NULL) and
2. "VALIDATED" (where struct acpi_table_desc.Pointer is always not NULL).
During acpi_initialize_tables(), table state are ensured to be "INSTALLED"
but not "VALIDATED". This logic is ensured by the original code in very
ambigious way. For example, currently acpi_tb_delete_table() is invoked in
some place to perform an uninstallation while it is invoked in other place
to perform an invalidation. They happen to work just because no one enters
the penalty where the 2 behaviours are not equivalent.
The naming cleanups are made in this patch:
A. For installation and validation:
There is code setting struct acpi_table_desc.Pointer first and delete it
immediately to keep the descriptor's state as "INSTALLED" during the
installation. This patch implements this in more direct way. After
applying it, struct acpi_table_desc.Pointer will never be set in
acpi_tb_install_table() and acpi_tb_override_table() as they are the only
functions invoked during acpi_initialize_tables(). This is achieved by:
1. Rename acpi_tb_verify_table() to acpi_tb_validate_table() to clarify this
change.
2. Rename acpi_tb_table_override() to acpi_tb_override_table() to keep nameing
consistencies as other APIs (verb. Table).
3. Stops setting struct acpi_table_desc.Pointer in acpi_tb_install_table() and
acpi_tb_table_override().
4. Introduce acpi_tb_acquire_table() to acquire the table pointer that is not
maintained in the struct acpi_table_desc of the global root table list and
rewrite acpi_tb_validate_table() using this new function to reduce
redundancies.
5. Replace the table pointer using the overridden table pointer in
acpi_tb_add_table(). As acpi_tb_add_table() is not invoked during early boot
stage, tables returned from this functions should be "VALIDATED". As
acpi_tb_override_table() is modified by this patch to return a "INSTALLED"
but not "VALIDATED" descriptor, to keep acpi_tb_add_table() unchanged,
struct acpi_table_desc.Pointer is filled in acpi_tb_add_table().
B. For invalidation and uninstallation:
The original code invalidate table by invoking acpi_tb_delete_table() here
and there, but actually this function should only be used to uninstall
tables. This can work just because its invocations are equivalent to
invalidation in some cases.
This patch splits acpi_tb_delete_table() into acpi_tb_invalidate_table() and
acpi_tb_uninstall_table() and cleans up the hidden logic using the new
APIs. This is achieved by:
1. Rename acpi_tb_delete_table() to acpi_tb_uninstall_table() as it is mainly
called before resetting struct acpi_table_desc.Address. Thus the table
descriptor is in "not INSTALLED" state. This patch enforces this by
setting struct acpi_table_desc.Address to NULL in this function.
2. Introduce acpi_tb_invalidate_table() to be the reversal of
acpi_tb_validate_table() and invoke it in acpi_tb_uninstall_table().
3. Introduce acpi_tb_release_table() to release the table pointer that is not
maintained in acpi_gbl_root_table_list and rewrite acpi_tb_invalidate_table()
using this new function to reduce redundancies.
After cleaning up, the maintainability of the internal APIs are also
improved:
1. acpi_tb_acquire_table: Acquire struct acpi_table_header according to
ACPI_TABLE_ORIGIN_xxx flags.
2. acpi_tb_release_table: Release struct acpi_table_header according to
ACPI_TABLE_ORIGIN_xxx flags.
3. acpi_tb_install_table: Make struct acpi_table_desc.Address not NULL according to
ACPI_TABLE_ORIGIN_xxx flags.
4. acpi_tb_uninstall_table: Make struct acpi_table_desc.Address NULL according to
ACPI_TABLE_ORIGIN_xxx flags.
5. acpi_tb_validate_table: Make struct acpi_table_desc.Pointer not NULL according to
ACPI_TABLE_ORIGIN_xxx flags.
6. acpi_tb_invalidate_table: Make struct acpi_table_desc.Pointer NULL according to
ACPI_TABLE_ORIGIN_xxx flags.
7. acpi_tb_override_table: Replace struct acpi_table_desc.Address and
struct acpi_table_desc.Flags. It only happens in
"INSTALLED" state.
The patch has been unit tested in acpi_exec by:
1. Initializing;
2. Executing exc_tbl ASLTS tests;
3. Executing "Load" command.
So that all original acpi_tb_install_table() and acpi_tb_override_table()
invocations are covered.
Known Issues:
1. Cleanup acpi_tb_add_table() to Kill Code Redundancies
Current implementation in acpi_tb_add_table() is not very clean, further
patch can rewrite acpi_tb_add_table() with ordered acpi_tb_install_table(),
acpi_tb_override_table() and acpi_tb_validate_table(). It is not done in this
patch so that it is easy for the reviewers to understand the changes in
this patch.

interfaces.
This changes can reduce source code differences between Linux and ACPICA
upstream to help improving the release automation.
The side effect of applying this patch in Linux is:
1. Some ACPICA initialization/termination APIs are no longer exported in
Linux, these include:
acpi_load_tables
acpi_initialize_subsystem
acpi_enable_subsystem
acpi_initialize_objects
acpi_terminate
2. This patch does not affect the following APIs as they are currently not
marked with ACPI_EXPORT_SYMBOL in Linux:
acpi_reallocate_root_table
acpi_initialize_tables
Such functions should not be exported as they are internal to ACPI
subsystem in Linux, and will only be invoked inside of ACPI subsystem's
initialization routines marked with __init and termination routines marked
with __exit. While on other OSPMs, such functions may still need to be
exported.
Thus this patch adds the configurability for ACPICA, so that it leaves
OSPMs to determine if the __init/__exit marked functions should be exported
or not. Lv Zheng.

to prevent wrongly overwriting fixmap that still want to use.
ACPI used to rely on low mappings being all linearly mapped and
grew a habit: it never really unmapped certain kinds of tables
after use.
This can cause problems - for example the hypothetical case
when some spurious access still references it.
v2: remove prev_map and prev_size in __apci_map_table
v3: let acpi_os_unmap_memory() call early_iounmap too, so remove extral calling to
early_acpi_os_unmap_memory
v4: fix typo in one acpi_get_table_with_size calling
