dmi: Mark all struct dmi_system_id instances const

2017-09-14T09:59:30+00:00

... and __initconst if applicable.

Based on similar work for an older kernel in the Grsecurity patch.

[JD: fix toshiba-wmi build]
[JD: add htcpen]
[JD: move __initconst where checkscript wants it]

ACPI / blacklist: add acpi_match_platform_list()

2017-08-28T23:42:48+00:00

ACPI OEM ID / OEM Table ID / Revision can be used to identify
a platform based on ACPI firmware info.  acpi_blacklisted(),
intel_pstate_platform_pwr_mgmt_exists(), and some other funcs,
have been using similar check to detect a list of platforms
that require special handlings.

Move the platform check in acpi_blacklisted() to a new common
utility function, acpi_match_platform_list(), so that other
drivers do not have to implement their own version.

There is no change in functionality.

ACPI / blacklist: add _REV quirk for Dell Inspiron 7537

2017-04-19T00:35:54+00:00

The battery can only be detected after AC power adapter event.

Adding the machine to acpi_rev_dmi_table[] can work around this
issue.

ACPI / blacklist: Make Dell Latitude 3350 ethernet work

2016-11-16T22:01:29+00:00

The Dell Latitude 3350's ethernet card attempts to use a reserved
IRQ (18), resulting in ACPI being unable to enable the ethernet.

Adding it to acpi_rev_dmi_table[] helps to work around this problem.

ACPI / blacklist: add _REV quirks for Dell Precision 5520 and 3520

2016-11-16T21:57:39+00:00

Precision 5520 and 3520 either hang at login and during suspend or reboot.

It turns out that that adding them to acpi_rev_dmi_table[] helps to work
around those issues.

ACPI / osi: Collect _OSI handling into one single file

2016-05-04T22:13:53+00:00

_OSI handling code grows giant and it's time to move them into one file.

This patch collects all _OSI handling code into one single file.
So that we only have the following functions to be used externally:

 early_acpi_osi_init(): Used by DMI detections;
 acpi_osi_init(): Used to initialize OSI command line settings and install
                  Linux specific _OSI handler;
 acpi_osi_setup(): The API that should be used by the external quirks.
 acpi_osi_is_win8(): The API is used by the external drivers to determine
                     if BIOS supports Win8.

CONFIG_DMI is not useful as stub dmi_check_system() can make everything
stub because of strip.

No functional changes.

ACPI / osi: Cleanup coding style issues before creating a separate OSI source file

2016-05-04T22:13:52+00:00

This patch performs necessary cleanups before moving OSI support to
another file.

 1. Change printk into pr_xxx
 2. Do not initialize values to 0
 3. Do not append additional "return" at the end of the function
 4. Remove useless comments which may easily break line breaking rule

After fixing the coding style issues, rename functions to make them looking
like acpi_osi_xxx.

No functional changes.

ACPI / osi: Fix default _OSI(Darwin) support

2016-05-04T22:13:52+00:00

The following commit always reports positive value when Apple hardware
queries _OSI("Darwin"):

 Commit: 7bc5a2bad0b8d9d1ac9f7b8b33150e4ddf197334
 Subject: ACPI: Support _OSI("Darwin") correctly

However since this implementation places the judgement in runtime, it
breaks acpi_osi=!Darwin and cannot return unsupported for _OSI("WinXXX")
invoked before invoking _OSI("Darwin").

This patch fixes the issues by reverting the wrong support and implementing
the default behavior of _OSI("Darwin")/_OSI("WinXXX") on Apple hardware via
DMI matching.
