ACPICA commit aaace77db4c3b267a65b75c33f84ace6f65bbcf7
Originally, when acpi_gbl_use32_bit_fadt_addresses is TRUE, GAS override can
only happen when the Address field mismatches.
According to the investigation result, Windows may favor 32-bit FADT
addresses in some cases. So we need this quirk working after enabling full
GAS support. This requires us to override GAS access_size/bit_width/bit_offset
fields as long as acpi_gbl_use32_bit_fadt_addresses is TRUE.
This patch enhances this quirk mechanism to make it working with full GAS
support. Lv Zheng.

Some logics actually relying on the existence of FADT, currently relies on
the number of loaded tables. This false dependency can easily trigger
regressions. One of them has been introduced by commit 8ec3f45907
(ACPICA: Tables: Fix global table list issues by removing fixed table).
The commit changing the fixed table indexes results in the change of FADT
table index, originally, it was 3 (thus the installed table count should be
greater than 4), while currently it is 0 (and the installed table count may
be 3).
This patch fixes this regression by cleaning up the code. Lv Zheng.

ACPICA commit c0b38b4c3982c2336ee92a2a14716107248bd941
The fixed table indexes leave holes in the global table list:
1. One hole can be seen when there is only 1 FACS provided by the BIOS.
2. Tow holes can be seen when it is a reduced hardware platform.
The holes do not break OSPMs but have broken ACPI debugger "tables"
command.
Also the "fixed table indexes" mechanism may make the descriptors of the
standard tables installed earlier than DSDT to be overwritten by the
descriptors of the fixed tables. For example, FACP disappears from the
global table list after DSDT is installed.
This patch fixes all above issues by removing the "fixed table indexes"
mechanism which is too complicated to be maintained in a regression safe
manner. After removal, the table loader will determine the indexes of the
fixed tables. Lv Zheng.

ACPICA commit f7b86f35416e3d1f71c3d816ff5075ddd33ed486
The following commit is reported to have broken s2ram on some platforms:
Commit: 0249ed2444
ACPICA: Add option to favor 32-bit FADT addresses.
The platform reports 2 FACS tables (which is not allowed by ACPI
specification) and the new 32-bit address favor rule forces OSPMs to use
the FACS table reported via FADT's X_FIRMWARE_CTRL field.
The root cause of the reported bug might be one of the followings:
1. BIOS may favor the 64-bit firmware waking vector address when the
version of the FACS is greater than 0 and Linux currently only supports
resuming from the real mode, so the 64-bit firmware waking vector has
never been set and might be invalid to BIOS while the commit enables
higher version FACS.
2. BIOS may favor the FACS reported via the "FIRMWARE_CTRL" field in the
FADT while the commit doesn't set the firmware waking vector address of
the FACS reported by "FIRMWARE_CTRL", it only sets the firware waking
vector address of the FACS reported by "X_FIRMWARE_CTRL".
This patch excludes the cases that can trigger the bugs caused by the root
cause 2.
There is no handshaking mechanism can be used by OSPM to tell BIOS which
FACS is currently used. Thus the FACS reported by "FIRMWARE_CTRL" may still
be used by BIOS and the 0 value of the 32-bit firmware waking vector might
trigger such failure.
This patch tries to favor 32bit FACS address in another way where both the
FACS reported by "FIRMWARE_CTRL" and the FACS reported by "X_FIRMWARE_CTRL"
are loaded so that further commit can set firmware waking vector in the
both tables to ensure we can exclude the cases that trigger the bugs caused
by the root cause 2. The exclusion is split into 2 commits as this commit
is also useful for dumping more ACPI tables, it won't get reverted when
such exclusion is no longer necessary. Lv Zheng.

The original table handling code does not always verify checksums before
installing a table, this is because code to achieve this must be
implemented here and there in the redundant code blocks.
There are two stages during table initialization:
1. "INSTALLED" after acpi_tb_install_table() and acpi_tb_override_table(),
struct acpi_table_desc.Pointer is ensured to be NULL. This can be safely used
during OSPM's early boot stage.
2. "VALIDATED" after acpi_tb_validate_table(), struct acpi_table_desc.Pointer is
ensured to be not NULL. This must not be used during OSPM's early boot
stage.
This patch changes acpi_tb_add_table() into an early boot safe API to reduce
code redundancies by changing the table state that is returned by this
function from "VALIDATED" to "INSTALLED". Then the table verification
code can be done in a single place. Originally, the acpi_tb_add_table() can
only be used by dynamic table loadings that are executed after early boot
stage, it cannot be used by static table loadings that are executed in
early boot stage as:
1. The address of the table is a virtual address either maintained by
OSPMs who call acpi_load_table() or by ACPICA whenever "Load" or
"LoadTable" opcodes are executed, while during early boot stage,
physical address of the table should be used for table loading.
2. The API will ensure the state of the loaded table to be "VALIDATED"
while during early boot stage, tables maintained by root table list
should be kept as "INSTALLED".
To achieve this:
1. Rename acpi_tb_install_table() to acpi_tb_install_fixed_table() as it only
applies to DSDT/FACS installation. Rename acpi_tb_add_table() to
acpi_tb_install_non_fixed_table() as it will be applied to the installation
of the rest kinds of tables.
2. Introduce acpi_tb_install_table(), acpi_tb_install_and_override_table to collect
redudant code where their invocations actually have slight differences.
1. acpi_tb_install_table() is used to fill an struct acpi_table_desc where the
table length is known to the caller.
2. acpi_tb_install_and_override_table() is used to perform necessary
overriding before installation.
3. Change a parameter of acpi_tb_install_non_fixed_table() from struct acpi_table_desc
to acpi_physical_address to allow it to be invoked by static table
loadings. Also cleanup acpi_ex_load_op() and acpi_load_table() to accomodate
to the parameter change.
4. Invoke acpi_tb_install_non_fixed_table() for all table loadings other than
DSDT/FACS in acpi_tb_parse_root_table() to improve code maintainability
(logics are collected in the single function). Also delete useless code
from acpi_tb_parse_root_table().
5. Remove all acpi_tb_validate_table() from acpi_tb_install_non_fixed_table() and
acpi_tb_install_fixed_table() so that the table descriptor is kept in the
state of "INSTALLED" but not "VALIDATED" after returning from these
functions.
6. Introduce temporary struct acpi_table_desc (new_table_desc/old_table_desc) into
the functions to indicate a table descriptor that is not maintained by
acpi_gbl_root_table_list. Introduce acpi_tb_acquire_temporal_table() and
acpi_tb_release_temporal_table() to handle the use cases of such temporal
tables. They are only used for verified installation.
7. Introduce acpi_tb_verify_table() to validate table and verify table
checksum, also remove table checksum verification from
acpi_tb_validate_table(). Invoke acpi_tb_validate_table() in the functions
that will convert a table into "LOADED" state or invoke it from
acpi_get_table_XXX() APIs. Invoke acpi_tb_verify_table() on temporary
struct acpi_table_desc(s) that are going to be "INSTALLED".
8. Change acpi_tb_override_table() logic so that a temporary struct acpi_table_desc
will be overridden before installtion, this makes code simpler.
After applying the patch, tables are always installed after being
overridden and the table checksums are always verified before installation.

commit 64b3db22c0 (2.6.39),
"Remove use of unreliable FADT revision field" causes regression
for old P4 systems because now cst_control and other fields are
not reset to 0.
The effect is that acpi_processor_power_init will notice
cst_control != 0 and a write to CST_CNT register is performed
that should not happen. As result, the system oopses after the
"No _CST, giving up" message, sometimes in acpi_ns_internalize_name,
sometimes in acpi_ns_get_type, usually at random places. May be
during migration to CPU 1 in acpi_processor_get_throttling.
Every one of these settings help to avoid this problem:
- acpi=off
- processor.nocst=1
- maxcpus=1
The fix is to update acpi_gbl_FADT.header.length after
the original value is used to check for old revisions.

(GAS) addresses. The 64-bit addresses are only used if the 32-bit
addresses are zero. This change provides compatibility with all
versions of Windows. The worst case that this solves is when both
the 32-bit and 64-bit addresses are non-zero, but only the 32-bit
addresses are actually valid. This appears to happen in some
BIOSes because in this case, Windows uses the 32-bit addresses.

Incorrect register length mismatch between the 32 and 64 bit
registers in some cases. Code was was checking the wrong pointer
for non-zero, should be looking at the address within the GAS
structure.

Add new globals for the PM1 status registers (A/B), similar to the
way the PM1 enable registers are handled. Instead of overloading
the FADT Event Register blocks. This makes the code clearer and
less prone to error.
