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 enables the firmware waking vectors for both 32bit/64bit FACS
tables in order to ensure we can exclude the cases that trigger the bugs
caused by the root cause 2. The exclusion is split into 2 commits so that
if it turns out not to be necessary, this single commit can be reverted
without affecting the useful one. Lv Zheng, Bob Moore.

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

is also useful for dumping more ACPI tables, it won't get reverted when

ACPICA commit 7aa598d711644ab0de5f70ad88f1e2de253115e4
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 1.
ACPI specification says:
A. 32-bit FACS address (FIRMWARE_CTRL field in FADT):
Physical memory address of the FACS, where OSPM and firmware exchange
control information.
If the X_FIRMWARE_CTRL field contains a non zero value then this field
must be zero.
A zero value indicates that no FACS is specified by this field.
B. 64-bit FACS address (X_FIRMWARE_CTRL field in FADT):
64bit physical memory address of the FACS.
This field is used when the physical address of the FACS is above 4GB.
If the FIRMWARE_CTRL field contains a non zero value then this field
must be zero.
A zero value indicates that no FACS is specified by this field.
Thus the 32bit and 64bit firmware waking vector should indicate completely
different resuming environment - real mode (1MB addressable) and non real
mode (4GB+ addressable) and currently Linux only supports resuming from
real mode.
This patch enables 64-bit firmware waking vector for selected FACS via new
acpi_set_firmware_waking_vectors() API so that it's up to OSPMs to
determine which resuming mode should be used by BIOS and ACPICA changes
won't trigger the bugs caused by the root cause 1. Lv Zheng.

There is code in acpi_hw_build_pci_list() destructing returned object
(return_list_head) before touching it while the allocated new object
(list_head) is not tracked correctly to be destructed on the error case,
which is detected as unsecure code by the "Coverity" tool.
This patch fixes this issue by always intializing the returned object in
acpi_hw_build_pci_list() so that the caller of acpi_hw_build_pci_list() needn't
initialize it and always using the returned object to track the new
allocated objects. Lv Zheng.

It is reported that ACPI interrupts do not work any more on
Dell Latitude D600 after commit c50f13c672 (ACPICA: Save
current masks of enabled GPEs after enable register writes).
The problem turns out to be related to the fact that the
enable_mask and enable_for_run GPE bit masks are not in
sync (in the absence of any system suspend/resume events)
for at least one GPE register on that machine.
Address this problem by writing the enable_for_run mask into
enable_mask as soon as enable_for_run is updated instead of
doing that only after the subsequent register write has
succeeded. For consistency, update acpi_hw_gpe_enable_write()
to store the bit mask to be written into the GPE register
in enable_mask unconditionally before the write.
Since the ACPI_GPE_SAVE_MASK flag is not necessary any more after
that, drop it along with the symbols depending on it.

ACPICA commit 7af00219681ab35ebe57d64a9189fd04a5a026d8
Windows uses a value of 2, and has no plans to ever change this. So, _REV is
essentially useless for its primary purpose.
Worse, some BIOS vendors have used the difference in _REV values between
Windows and ACPICA to indicate which one is running.
It has been decided by the ACPI community to deprecate this method, and return
1 for ACPI 1.0 (32-bit integers) and 2 for ACPI 2.0 and greater (both 32-bit
and 64-bit integers.

This change adds the basic low-level infrastructure for the External
AML opcode. The interpreter will simply ignore this op, as the op
is intended for use by the disassembler only.
Note that External() opcode is useful for disassembler, interpreter
can simply ignore it and still return exceptions for unknown control
methods so the kernel part only includes the grammar definition of
External() opcode in order to ignore it but doesn't interpret it.

ACPICA commit f92a08512b0b35dce4a7fc6a73216674a3c2541b
Some conditional compilation definitions are wrong across header and source
files. This patch corrects them for the resources component.
NOTE that a further patch in this patchset cleans up all ACPI_EXEC_APP,
converting them into ACPI_DEBUGGER, including part of this change.

ACPICA commit 6eb364d790dd103bd4990f808e0095a421c437cb
acpi_tb_store_table() implements a logic that is only correct to iasl. So it
won't be used by any other utilities except iasl. This function is
complained by the kernel users as an unused function. The best choice to
stop releasing it to the Linux kernel should be moving it to adisasm.c.
ACPI table manager can use both struct acpi_table_desc (direct referencing)
and table index (indirect referencing) as the descriptor to the table, so
acpi_tb_get_next_root_index() is extended to return both of them to allow
maximum usability from the callers. NOTE that indirect referencing is a
design result to meet the boot stage static allocation requirement for the
table descriptors.
This is a linuxized acpi_tb_store_table() removing result, there should be
no functional changes introduced to the Linux kernel by this patch except
the additonal kernel unused argument for acpi_tb_get_next_root_index()
(renamed to acpi_tb_get_next_root_index()). This argument is used in the
ACPICA upstream.

ACPICA commit e25d791e4b3d5b9f4ead298269610cb05f89749a
There is a facility in Linux, developers can obtain GPE and fixed event
status via /sys/firmware/interrupts/. This is implemented using
acpi_get_event_status() and acpi_get_gpe_status(). Recently while debugging some
GPE race issues, it is found that the facility is lacking in the ability to
obtain real hardware register values, the confusing information makes
debugging difficult.
This patch modifies acpi_get_gpe_status() to return EN register values to fix
this gap. Then flags returned from acpi_get_event_status() and
acpi_get_gpe_status() are also cleaned up to reflect this change.
The old ACPI_EVENT_FLAG_SET is carefully kept to avoid regressions. It can
be deleted after we can make sure all its references are removed from OSPM
code. Lv Zheng.

ACPI_MTX_TABLES is acquired and released by the callers of
acpi_tb_install_standard_table() so releasing it in the function itself is
causing the following error in Linux kernel if the table is reloaded:

ACPICA commit b60612373a4ef63b64a57c124576d7ddb6d8efb6
For physical addresses, since the address may exceed 32-bit address range
after calculation, we should use 0x%8.8X%8.8X instead of ACPI_PRINTF_UINT
and ACPI_FORMAT_UINT64() instead of
ACPI_FORMAT_NATIVE_UINT()/ACPI_FORMAT_TO_UINT().
This patch also removes above replaced macros as there are no users.
This is a preparation to switch acpi_physical_address to 64-bit on 32-bit
kernel builds.

ACPICA commit 154f6d074dd38d6ebc0467ad454454e6c5c9ecdf
There are code pieces converting pointers using "(acpi_physical_address) x"
or "ACPI_CAST_PTR (t, x)" formats, this patch cleans up them.
Known issues:
1. Cleanup of "(ACPI_PHYSICAL_ADDRRESS) x" for a table field
For the conversions around the table fields, it is better to fix it with
alignment also fixed. So this patch doesn't modify such code. There
should be no functional problem by leaving them unchanged.

OSPMs like Linux expect an acpi_physical_address returning value from
acpi_find_root_pointer(). This triggers warnings if sizeof (acpi_size) doesn't
equal to sizeof (acpi_physical_address):
