Previous change in the AML parser code blindly set all non-successful
dispatcher statuses to AE_OK. That approach is incorrect, though,
because successful control method invocations from module-level
return AE_CTRL_TRANSFER. Overwriting AE_OK to this status causes the
AML parser to think that there was no return value from the control
method invocation.

The dispatcher and the executer process the parse nodes During table
load. Error status from the evaluation confuses the AML parser. This
results in the parser failing to complete parsing of the current
scope op which becomes problematic. For the incorrect AML below, _ADR
never gets created.
definition_block(...)
{
Scope (\_SB)
{
Device (PCI0){...}
Name (OBJ1, 0x0)
OBJ1 = PCI0 + 5 // Results in an operand error.
} // \_SB not closed
// parser looks for \_SB._SB.PCI0, results in AE_NOT_FOUND error
// Entire scope block gets skipped.
Scope (\_SB.PCI0)
{
Name (_ADR, 0x0)
}
}
Fix the above error by properly completing the initial \_SB scope
after an error by clearing errors that occur during table load. In
the above case, this means that OBJ1 = PIC0 + 5 is skipped.

After commit 18996f2db9 (ACPICA: Events: Stop unconditionally
clearing ACPI IRQs during suspend/resume) the status of ACPI events
is not cleared any more when entering the ACPI S5 system state (power
off) which causes some systems to power up immediately after turing
off power in certain situations.
That is a functional regression, so address it by making the code
clear the status of all ACPI events again when entering S5 (for
system-wide suspend or hibernation the clearing of the status of all
events is not desirable, as it might cause the kernel to miss wakeup
events sometimes).

This change alters the parser so that the table load does not abort
upon an error.
Notable changes:
If there is an error while parsing an element of the termlist, we
will skip parsing the current termlist element and continue parsing
to the next opcode in the termlist.
If we get an error while parsing the conditional of If/Else/While or
the device name of Scope, we will skip the body of the statement all
together and pop the parser_state.
If we get an error while parsing the base offset and length of an
operation region declaration, we will remove the operation region
from the namespace.

As the acpi code disables interrupts in acpi_idle_enter_bm, and calls
code that grabs the acpi lock, it causes issues as the lock is currently
in RT a sleeping lock.
The lock was converted from a raw to a sleeping lock due to some
previous issues, and tests that showed it didn't seem to matter.
Unfortunately, it did matter for one of our boxes.
This patch converts the lock back to a raw lock. I've run this code on a
few of my own machines, one being my laptop that uses the acpi quite
extensively. I've been able to suspend and resume without issues.

which on some systems does rely on op_regions.
Calling _STA before things are ready leads to errors such as these
(under Linux, on some hardware):
[ 0.123579] ACPI Error: No handler for Region [ECRM] (00000000ba9edc4c)
[generic_serial_bus] (20170831/evregion-166)
[ 0.123601] ACPI Error: Region generic_serial_bus (ID=9) has no handler

[ 0.123618] ACPI Error: Method parse/execution failed
\_SB.I2C1.BAT1._STA, AE_NOT_EXIST (20170831/psparse-550)
End 2015 support for the _SUB method was removed for exactly the same
reason. Removing current_status from struct acpi_device_info only has a limited
impact. Within ACPICA it is only used by 2 debug messages, both
of which are modified to no longer print it with this commit.
Outside of ACPICA, there was one user in Linux, which has been patched to
no longer use current_status in Torvald's current master.
I've not checked if free_BSD or others are using the current_status field.

After being enabled for the first time, the GPEs may have STS bits already
set. Setting EN bits is not sufficient to trigger the GPEs again, so this
patch polls GPEs after enabling them for the first time.
This is a cleaner version on top of the "GPE clear" fix generated according
to Mika's report and Rafael's original Linux based fix. Based on Linux

There is a risk that a GPE method/handler may be invoked twice. Let's
consider a case, both GPE0(RAW_HANDLER) and GPE1(_Exx) is triggered.
=======================================+=============================
IRQ handler (top-half) |IRQ polling
=======================================+=============================
acpi_ev_detect_gpe() |
LOCK() |
READ (GPE0-7 enable/status registers)|
^^^^^^^^^^^^ROOT CAUSE^^^^^^^^^^^^^^^|
Walk GPE0 |
UNLOCK() |LOCK()
Invoke GPE0 RAW_HANDLER |READ (GPE1 enable/status bit)
|acpi_ev_gpe_dispatch(irq=false)
| CLEAR (GPE1 enable bit)
| CLEAR (GPE1 status bit)
LOCK() |UNLOCK()
Walk GPE1 +=============================
acpi_ev_gpe_dispatch(irq=true) |IRQ polling (defer)
CLEAR (GPE1 enable bit) +=============================
CLEAR (GPE1 status bit) |acpi_ev_async_execute_gpe_method()
Walk others | Evaluate GPE1 _Exx
fi | acpi_ev_async_enable_gpe()
UNLOCK() | LOCK()
=======================================+ SET (GPE enable bit)
IRQ handler (bottom-half) | UNLOCK()
=======================================+
acpi_ev_async_execute_gpe_method() |
Evaluate GPE1 _Exx |
acpi_ev_async_enable_gpe() |
LOCK() |
SET (GPE1 enable bit) |
UNLOCK() |
=======================================+=============================
If acpi_ev_detect_gpe() is only invoked from the IRQ context, there won't be
more than one _Lxx/_Exx evaluations for one status bit flagging if the IRQ
handlers controlled by the underlying IRQ chip/driver (ex. APIC) are run in
serial. Note that, this is a known potential gap and we had an approach,
locking entire non-raw-handler processes in the top-half IRQ handler and
handling all raw-handlers out of the locked loop to be friendly to those
IRQ chip/driver. But the approach is too complicated while the issue is not
so real, thus ACPICA treated such issue (if any) as a parallelism/quality
issue of the underlying IRQ chip/driver to stop putting it on the radar.
Bug in link #1 is suspiciously reflecting the same cause, and if so, it can
also be fixed by this simpler approach.
But it will be no excuse an ACPICA problem now if ACPICA starts to poll
IRQs itself. In the changed scenario, _Exx will be evaluated from the task
context due to new ACPICA provided "polling after enabling GPEs" mechanism.
And the above figure uses edge-triggered GPEs demonstrating the possibility
of evaluating _Exx twice for one status bit flagging.
As a conclusion, there is now an increased chance of evaluating _Lxx/_Exx
more than once for one status bit flagging.
However this is still not a real problem if the _Lxx/_Exx checks the
underlying hardware IRQ reasoning and finally just changes the 2nd and the
follow-up evaluations into no-ops. Note that _Lxx should always be written
in this way as a level-trigger GPE could have it's status wrongly
duplicated by the underlying IRQ delivery mechanisms. But _Exx may have
very low quality BIOS by BIOS to trigger real issues. For example, trigger
duplicated button notifications.
To solve this issue, we need to stop reading a bunch of enable/status
register bits, but read only one GPE's enable/status bit. And GPE status
register's W1C nature ensures that acknowledging one GPE won't affect
another GPEs' status bits. Thus the hardware GPE architecture has already
provided us with the mechanism of implementing such parallelism.
So we can lock around one GPE handling process to achieve the parallelism:
1. If we can incorporate GPE enable bit check in detection and ensure the
atomicity of the following process (top-half IRQ handler):
READ (enable/status bit)
if (enabled && raised)
CLEAR (enable bit)
and handle the GPE after this process, we can ensure that we will only
invoke GPE handler once for one status bit flagging.
2. In addtion for edge-triggered GPEs, if we can ensure the atomicity of
the following process (top-half IRQ handler):
READ (enable/status bit)
if (enabled && raised)
CLEAR (enable bit)
CLEAR (status bit)
and handle the GPE after this process, we can ensure that we will only
invoke GPE handler once for one status bit flagging.
By doing a cleanup in this way, we can remove duplicate GPE handling code
and ensure that all logics are collected in 1 function. And the function
will be safe for both IRQ interrupt and IRQ polling, and will be safe for
us to release and re-acquire acpi_gbl_gpe_lock at any time rather than raw
handler only during the top-half IRQ handler. Lv Zheng.

Unconditionally clearing ACPI IRQs during suspend/resume can lead to
unexpected IRQ losts. This patch fixes this issue by removing such IRQ
clearing code.
If this patch triggers regression, the regression should be in the GPE
handlers that cannot correctly determine some spurious triggered events as
no-ops. Please report any regression related to this commit to the ACPI

For the kernel-resident ACPICA, optionally be silent about the
NOT_FOUND case. Although this is potentially a serious problem,
it can generate a lot of noise/errors on platforms whose
firmware carries around a bunch of unused Package objects.
To disable these errors, define ACPI_IGNORE_PACKAGE_RESOLUTION_ERRORS

ACPICA commit 8faf6fca445eb7219963d80543fb802302a7a8c7
This change completes the integration of the recent changes to
package object handling with the module-level code support.
For acpi_exec, the -ep flag is removed.
This change allows table load to behave as if it were a method
invocation. Before this, the definition block definition below would
have loaded all named objects at the root scope. After loading, it
would execute the if statements at the root scope.
DefinitionBlock (...)
{
Name(OBJ1, 0)
if (1)
{
Device (DEV1)
{
Name (_HID,0x0)
}
}
Scope (DEV1)
{
Name (OBJ2)
}
}
The above code would load OBJ1 to the namespace, defer the execution
of the if statement and attempt to add OBJ2 within the scope of DEV1.
Since DEV1 is not in scope, this would incur an AE_NOT_FOUND error.
After this error is emitted, the if block is invoked and DEV1 and its
_HID is added to the namespace.
This commit changes the behavior to execute the if block in place
rather than deferring it until all tables are loaded. The new
behavior is as follows: insert OBJ1 in the namespace, invoke the if
statement and add DEV1 and its _HID to the namespace, add OBJ2 to the
scope of DEV1.

The declaration External (ABCD.EFGH) creates two nodes in the namespace: ABCD
and EFGH where ABCD is marked as an implicit external node. ABCD is labeled as
implicit because there does not exist a specific External (ABCD) declaration.
Before this change, the declaration External (ABCD.EFGH) and
External (ABCD.EFGH.IJKL) creates the namespace nodes ABCD, EFGH, and IJKL
where ABCD and EFGH are labeled as implicit external nodes. This is incorrect.
The only implicit node should be ABCD because EFGH and IJKL are explicit nodes.
This change fixes the labeling procecess of external op namespace nodes so that
nodes are properly labeled as implicit external.

ACPICA commit 9605023e7e6d1f05581502766c8cf2905bcc03d9
This patch implements a new infinite loop detection mechanism to replace
the old one, it uses acpi_os_get_timer() to limit loop execution into a
determined time slice.
This is useful in case some hardware/firmware operations really require the
AML interpreter to wait while the old mechanism could expire too fast on
recent machines.
The new mechanism converts old acpi_gbl_max_loop_iterations to store the user
configurable value for the new mechanism in order to allow users to be
still able to configure this value for acpiexec via command line. This
patch also removes wrong initilization code of acpi_gbl_max_loop_iterations
accordingly (it should have been initialized by ACPI_INIT_GLOBAL, and the
default value is also properly tuned for acpiexec). Reported by M. Foronda,
fixed by Lv Zheng.

ACPICA commit 08a00639b0d6756e8ba1421419fc3728904651d9
The calls to acpi_os_acquire_object can result in a null being assigned
to Op (for example if a mutex acquire fails) which can lead to a
null pointer dereference on Op on the call to ASL_CV_TRANSFER_COMMENTS
(via function cv_transfer_comments). Move the block into the previous
block that checks for a null Op so that we never can call
cv_transfer_comments with a null Op.

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

ACPICA commit 04c28c7549e694ea85f40bcc816039e5fbb4169c
This patch adds testability of deferred table verification mechanism. As
acpiexec uses dynamically allocated root table list from its very early
stage, a change to acpi_reallocate_root_table() is required to allow deferred
table verification mechanism to be triggered in such an environment. Note
that acpi_gbl_enable_table_validation is still TRUE by default, thus:
1. Developers need to manually set acpi_gbl_enable_table_validation to FALSE
for acpiexec to enable this test.
2. For all other OSPMs (Linux, BSDs, etc.), this commit is a no-op.

Runtime GPEs have corresponding _Lxx/_Exx methods and are enabled
automatically during the initialization of the ACPI subsystem through
acpi_update_all_gpes() with the assumption that acpi_setup_gpe_for_wake()
will be called in advance for all of the GPEs pointed to by _PRW
objects in the namespace that may be affected by acpi_update_all_gpes().
That is, acpi_ev_initialize_gpe_block() can only be called for a GPE
block after acpi_setup_gpe_for_wake() has been called for all of the
_PRW (wakeup) GPEs in it.
The platform firmware on some systems, however, expects GPEs to be
enabled before the enumeration of devices which is when
acpi_setup_gpe_for_wake() is called and that goes against the above
assumption.
For this reason, introduce a new flag to be set by
acpi_ev_initialize_gpe_block() when automatically enabling a GPE
to indicate to acpi_setup_gpe_for_wake() that it needs to drop the
reference to the GPE coming from acpi_ev_initialize_gpe_block()
and modify acpi_setup_gpe_for_wake() accordingly. These changes
allow acpi_setup_gpe_for_wake() and acpi_ev_initialize_gpe_block()
to be invoked in any order.

In some cases GPEs are already active when they are enabled by
acpi_ev_initialize_gpe_block() and whatever happens next may depend
on the result of handling the events signaled by them, so the
events should not be discarded (which is what happens currently) and
they should be handled as soon as reasonably possible.
For this reason, modify acpi_ev_initialize_gpe_block() to
dispatch GPEs with the status flag set in-band right after
enabling them.

ACPICA commit 8b14afac65d983610cc5387ede6d85ea5ee075be
The following ACPI table contains an invalid target node within the
Alias operator:
definition_block ("", "SSDT", 1, "Bug", "BugTable", 0x00001000)
{
Scope (_SB)
{
Device (DEV0)
{
Name (_ADR, 1)
Device (DEV1)
{
Alias (_ADR, _ADR)
}
}
}
}
If an ACPI table contains such an invalid target node in an Alias
operator, a segmentation fault will occur when the target node is
dereferenced within acpi_ex_create_alias. Add a check for such an invalid
target node in acpi_ex_create_alias and return AE_NULL_OBJECT as suggested
by @acpibob.

ACPICA commit ffddee6638aced83be18b8bc88569586c1a43e03
This patch allows tables not verified in early stage verfied in
acpi_reallocate_root_table(). This is useful for OSPMs like linux where tables
cannot be verified in early stage due to early ioremp limitations on some
architectures. Reported by Hans de Geode, fixed by Lv Zheng.

ACPICA commit 182bdffc0644f568be614a6d4debd651e29ca587
They are all mechanisms used to verify if a table is qualified to be
installed and controlled by acpi_gbl_enable_table_validation, so combine them
together. By doing so, table duplication check is applied to the statically
loaded tables (however whether it is actually enabled is still determined
by acpi_gbl_enable_table_validation). Lv Zheng.

acpi_gbl_verify_table_checksum is used to avoid validating (mapping) an entire
table in OS boot stage. 2nd "Reload" check in acpi_tb_install_standard_table()
is prepared for the same purpose. So this patch combines them together

ACPICA commit d3c944f2cdc8c7e847b7942b1864f285189f7bce
Windows seems to allow arbitrary table signatures for Load/load_table
opcodes:
ACPI BIOS Error (bug): Table has invalid signature [PRAD] (0x44415250)
So this patch removes dynamic load signature checks. However we need to
find a way to avoid table loading against tables like MADT. This is not
covered by this commit.
This Windows behavior has been validated on link #1. An end user bug
report can also be found on link #2.
This patch also includes simple cleanup for static load signature check
code. Reported by Ye Xiaolong, Fixed by Lv Zheng.

ACPICA commit 894e49ef22db354eb1685cdb6f5f991766351d3c
acpisrc now has capability to convert both the followings:
1. Form 1:
typedef struct/union foo { struct/union foo {
.... --> ...
} FOO; }
2. Form 2:
typedef struct/union foo FOO; --> typedef struct/union foo foo;
It becomes unable to handle the following:
3. Form3:
typedef struct/union foo { /* comment */
...
} FOO;
-->
strut/union foo { /* comment */
...
};
As:
1. The purpose of acpisrc is to convert formatted code (ACPICA coding
style) into linux coding style,
2. acpisrc is a very simple tool that doesn't fully handle C language.
This commit changes the definitions side in order not to regress and we
shall make "no comments in struct/union line" as a new ACPICA coding style
rule. Lv Zheng.

Call directly into acpica to load a table to obtain its index on return.
We choose the direct call of acpica internal functions to avoid having
to modify its API which is used outside of Linux as well.
Use that index to unload the table again when the corresponding
directory in configfs gets removed. This allows to change SSDTs without
rebooting the system. It also allows to destroy devices again that a
dynamically loaded SSDT created.
This is widely similar to the DT overlay behavior.

An invalid opcode indicates something seriously wrong with the
input AML file. The AML parser is immediately confused and lost,
causing the resulting parse tree to be ill-formed. The actual
disassembly can then cause numerous unrelated errors and faults.
This change aborts the disassembly upon discovery of such an
opcode during the AML parse phase.
