PCI/ACPI: Allow ACPI to be built without CONFIG_PCI set

2018-12-20T09:19:49Z

We are compiling PCI code today for systems with ACPI and no PCI device present. Remove the useless code and reduce the tight dependency. Signed-off-by: Sinan Kaya Acked-by: Bjorn Helgaas # PCI parts Acked-by: Ingo Molnar Signed-off-by: Rafael J. Wysocki

ACPI / EC: Fix regression related to PM ops support in ECDT device

2017-11-20T23:13:02Z

On platforms (ASUS X550ZE and possibly all ASUS X series) with valid ECDT EC but invalid DSDT EC, EC PM ops won't be invoked as ECDT EC is not an ACPI device. Thus the following commit actually removed post-resume acpi_ec_enable_event() invocation for such platforms, and triggered a regression on them that after being resumed, EC (actually should be ECDT) driver stops handling EC events: Commit: c2b46d679b30c5c0d7eb47a21085943242bdd8dc Subject: ACPI / EC: Add PM operations to improve event handling for resume process Notice that the root cause actually is "ECDT is not an ACPI device" rather than "the timing of acpi_ec_enable_event() invocation", this patch fixes this issue by enumerating ECDT EC as an ACPI device. Due to the existence of the noirq stage, the ability of tuning the timing of acpi_ec_enable_event() invocation is still meaningful. This patch is a little bit different from the posted fix by moving acpi_config_boot_ec() from acpi_ec_ecdt_start() to acpi_ec_add() to make sure that EC event handling won't be stopped as long as the ACPI EC driver is bound. Thus the following sequence shouldn't disable EC event handling: unbind,suspend,resume,bind.

ACPI: Remove FSF mailing addresses

ACPI / PCI: Stub out pci_acpi_crs_quirks() and make it x86 specific

2014-05-06T23:09:47Z

For pci_acpi_crs_quirks(), ia64 already doesn't use it, and we can not foresee it should be used in ARM64, so stub out pci_acpi_crs_quirks() to avoid introducing platform specific dummy stub function. Signed-off-by: Hanjun Guo Reviewed-by: Bjorn Helgaas Signed-off-by: Rafael J. Wysocki

ACPI / dock: Drop struct acpi_dock_ops and all code related to it

2014-02-21T23:48:56Z

Since struct acpi_dock_ops and the code handling it don't have any users any more after the previous changes, drop that structure and the code related to it altogether. Signed-off-by: Rafael J. Wysocki

ACPI / dock: Use ACPI device object pointers instead of ACPI handles

2014-02-21T00:10:09Z

Rework the ACPI dock station driver to store ACPI device object pointers instead of ACPI handles in its internal data structures. The purpose is moslty to make subsequent simplifications possible, but also this allows the overall code size to be reduced slightly. Signed-off-by: Rafael J. Wysocki

ACPI: Clean up inclusions of ACPI header files

2013-12-07T00:03:14Z

Replace direct inclusions of , and , which are incorrect, with inclusions and remove some inclusions of those files that aren't necessary. First of all, , and should not be included directly from any files that are built for CONFIG_ACPI unset, because that generally leads to build warnings about undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set, includes those files and for CONFIG_ACPI unset it provides stub ACPI symbols to be used in that case. Second, there are ordering dependencies between those files that always have to be met. Namely, it is required that be included prior to so that the acpi_pci_root declarations the latter depends on are always there. And which provides basic ACPICA type declarations should always be included prior to any other ACPI headers in CONFIG_ACPI builds. That also is taken care of including as appropriate.

ACPI / dock / PCI: Drop ACPI dock notifier chain

2013-07-14T23:33:12Z

The only user of the ACPI dock notifier chain is the ACPI-based PCI hotplug (acpiphp) driver that uses it to carry out post-dock fixups needed by some systems with broken _DCK. However, it is not necessary to use a separate notifier chain for that, as it can be simply replaced with a new callback in struct acpi_dock_ops. For this reason, add a new .fixup() callback to struct acpi_dock_ops and make hotplug_dock_devices() execute it for all dock devices with hotplug operations registered. Accordingly, make acpiphp point that callback to the function carrying out the post-dock fixups and do not register a separate dock notifier for each device registering dock operations. Finally, drop the ACPI dock notifier chain that has no more users. Signed-off-by: Rafael J. Wysocki

ACPI / dock: Do not check CONFIG_ACPI_DOCK_MODULE

2013-07-14T23:33:11Z

Since commit 94add0f (ACPI / dock: Initialize ACPI dock subsystem upfront) the ACPI dock driver cannot be a module, so CONFIG_ACPI_DOCK_MODULE is never set. For this reason, simplify the preprocessor conditional in include/acpi/acpi_drivers.h referring to that sybbol unnecessarily. Signed-off-by: Rafael J. Wysocki
