module: Convert symbol namespace to string literal

2024-12-02T19:34:44Z

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

ACPI: introduce acpi_arch_init()

2024-11-22T20:32:25Z

To avoid arch-specific code in general ACPI initialization flow, introduce a weak symbol acpi_arch_init(). Currently, arm64 and riscv can utillize this to insert their arch-specific flow. In the future, other architectures can also have a chance to define their own arch-specific ACPI initialization process if necessary.

ACPI: EC: make EC support compile-time conditional

2024-10-24T15:47:15Z

The embedded controller code is mainly used on x86 laptops and cannot work without PC style I/O port access. Make this a user-visible configuration option that is default enabled on x86 but otherwise disabled, and that can never be enabled unless CONFIG_HAS_IOPORT is also available. The empty stubs in internal.h help ignore the EC code in configurations that don't support it. In order to see those stubs, the sbshc code also has to include this header and drop duplicate declarations. All the direct callers of ec_read/ec_write already had an x86 dependency and now also need to depend on APCI_EC.

xen/pvh: Setup gsi for passthrough device

2024-09-25T07:54:52Z

In PVH dom0, the gsis don't get registered, but the gsi of a passthrough device must be configured for it to be able to be mapped into a domU. When assigning a device to passthrough, proactively setup the gsi of the device during that process.

platform/x86: wmi: Remove wmi_get_event_data()

2024-09-05T15:21:59Z

Since the WMI driver core now takes care of retrieving the WMI event data even for legacy WMI notify handlers, this function is no longer used. Remove it to prevent WMI drivers from messing up the ACPI firmware on some machines.

platform/x86: wmi: Pass event data directly to legacy notify handlers

2024-09-05T15:21:59Z

The current legacy WMI handlers are susceptible to picking up wrong WMI event data on systems where different WMI devices share some notification IDs. Prevent this by letting the WMI driver core taking care of retrieving the event data. This also simplifies the legacy WMI handlers and their implementation inside the WMI driver core.

Add a new function for RISC-V to do architecture specific initialization similar to acpi_arm_init().
