jmcneill | acpi: i2c: only claim child devices with a _CRS or _ADR method
acpi_enter_i2c_devs is too aggressive with claiming child device nodes.
Restrict it to devices with either a _CRS or _ADR method. A driver is
free to claim more if appropriate.
Fixes missing HKEY (LEN0268) device on Thinkpad T14s Gen 6 (X1E).

jmcneill | acpi_match_cpu_info: Skip test for 'acpi_active'.
This allows us to call this function from acpi_md_callback, which is
when CPUs are attached on Arm.

thorpej | branches: 1.33.10;
- Handle dtlink in acpi_pack_compat_list().
- Don't pass the _HID value as the device name; always use the ACPI
node name.
|
| 1.32 |
| 22-Jan-2022 |
thorpej | Change the devhandle_from_*() functions to also take a "super handle",
from which the newly created handle will inherit it's implementation.
The root implementation for a new handle type is used if an invalid
"super handle" is passed.

jmcneill | acpi: Add helper for querying DSM function 0.
|

jmcneill | acpi: Add acpi_dsd_bool helper
|

jmcneill | acpi: Support DT link compat string lists
A "compatible" DSD property may either be a string, or a package of
strings. Support both variants in acpi_compatible_match.
|
| 1.28 |
| 26-Dec-2021 |
jmcneill | acpi: Support DT link device ID
The PRP0001 device ID is used to tell the OS to match a driver against
the "compatible" _DSD property. Make acpi_compatible_match aware of this
special device ID and match device compatible entries against the
compatible property when applicable.
|
| 1.27 |

skrll | Fix struct member prefix to be consistent. same code before and after.
|
| 1.26 |
| 15-Sep-2021 |
thorpej | Adjust the device_call() calling convention so as to provide type checking
of the arguments passed to the call, using auto-generated argument
structures and binding macros.
|
| 1.25 |
| 09-Aug-2021 |
andvar | fix various typos in compatibility, mainly in comments.
|
| 1.24 |
| 05-Feb-2021 |
thorpej | ACPI device handle implementation.
|
| 1.23 |
| 27-Jan-2021 |
thorpej | Introduce weighted matching for ACPI autoconfiguration, and provide
acpi_compatible_match() based around device_compatible_entry. Matches
against _HID score big, matches against _CID are weighted in the
standard most-to-least-specific ordering, less than _HID.
Also provide a maching value for _CLS, that's always less than _HID
and _CID matches, and use that in acpi_match_class().
Also provide acpi_compatible_lookup(), that returing the matching
entry based on the same criteria.

jmcneill | build fix
|
| 1.21 |
| 26-Jan-2021 |
jmcneill | Add a device_t parameter to acpi_enter_i2c_devs. If non-NULL, all child
acpi_devnodes will be claimed by that device so we don't later try to
attach a duplicate device to that node at acpinodebus.
|
| 1.20 |
| 14-Jan-2021 |
thorpej | - Add a new routine, acpi_pack_compat_list(), that packs the _HID
and _CID device ID strings into an OpenFirmware-like string list,
analogous to how the "compatible" property is represented in
OpenFirmware and the Device Tree specifications.
- Add generic routines for evaluating Device Specific Methods (_DSM).
|
| 1.19 |
| 23-Oct-2020 |
jmcneill | branches: 1.19.2;
Add acpi_intr_establish_irq, which is like acpi_intr_establish except
it takes a struct acpi_irq * instead of ACPI_HANDLE. Useful if a device
has more than one IRQ resource (acpi_intr_establish always picks the
first).
|
| 1.18 |
| 31-Dec-2019 |
mlelstv | Free buffers only when allocated.
|
| 1.17 |
| 29-Dec-2019 |
jmcneill | Add support for reading _DSD string property values.
|
| 1.16 |
| 22-Dec-2019 |
thorpej | Add acpi_intr_mask() and acpi_intr_unmask() which, following the pre-existing
ACPI software layering model, are wrappers around acpi_md_intr_mask() and
acpi_md_intr_unmask(), which in turn are wrappers around intr_mask() and
intr_unmask().
XXX ARM and IA64 implementations of acpi_md_intr_mask() and
acpi_md_intr_unmask() are just stubs for now.
|
| 1.15 |
| 21-Dec-2018 |
jmcneill | Add acpi_dsd_integer, which reads an integer value from an ACPI 5.0 _DSD
key/value package list.
|
| 1.14 |
| 16-Nov-2018 |
jmcneill | Use acpi_md_intr_establish/disestablish to handle device IRQs. The existing
code abused AcpiOsInstallInterruptHandler, which is meant for installing
the SCI handler.
|
| 1.13 |
| 12-Oct-2018 |
jmcneill | Add helper function to match a PCI-defined class/subclass/interface
against a _CLS object.
|
| 1.12 |
| 12-Oct-2018 |
jmcneill | Pull in sys/cpu.h for struct cpu_info and CPU_INFO_ITERATOR.

bouyer | branches: 1.11.2;
Allow registering ACPI interrupt handlers with a xname.
AcpiOsInstallInterruptHandler(), part of ACPICA API, doesn't allow passing
the xname. I extend the API with AcpiOsInstallInterruptHandler_xname()
for this purpose, and change acpi_md_OsInstallInterruptHandler() to
accept and use the xname (ia64 doens't use it).
The xname was hardcoded to "acpi SCI" in the
x86 acpi_md_OsInstallInterruptHandler(), so I make
AcpiOsInstallInterruptHandler() call
AcpiOsInstallInterruptHandler_xname with xname = "acpi SCI".
Now 'vmstat -i' shows the device's name instead of "acpi SCI" for for i2c HID
interrupts.
Proposed on tech-kern@ on Dec 29.

bouyer | branches: 1.10.2;
Cast to uintptr_t before casting to void *; fix a warning on i386
|
| 1.9 |
| 10-Dec-2017 |
bouyer | Implement a ACPI helper to fill the property array expected from our I2C
framework from the ACPI tables.
Also implement acpi_intr_establish(), acpi_intr_disestablish() and
acpi_intr_string().
Needed for the upcoming HID over I2C support, proposed on tech-kern@
on Dec, 1.
|
| 1.8 |
| 21-Jun-2011 |
jruoho | Rename acpi_get_node() to acpi_match_node() for consistency.
|
| 1.7 |
| 20-Jun-2011 |
jruoho | Add two new functions, acpi_match_cpu_info() and acpi_match_cpu_handle(),
which will match a given struct cpu_info with the corresponding ACPI handle,
and vice versa.
|
| 1.6 |
| 02-Nov-2010 |
gsutre | branches: 1.6.6;
acpi_eval_integer: check that the evaluation produced a result.
ok jruoho@
|
| 1.5 |
| 07-Jun-2010 |
jruoho | branches: 1.5.2;
Use the new ACPICA functions AcpiAttachData() and AcpiGetData() to associate
all "struct acpi_devnodes" to their corresponding ACPI_HANDLEs. Anywhere in
the acpi(4) subtree, the node-structure can be obtained from a handle via
acpi_get_node(). The idea is similar to e.g. device_private().
Benefits: (a) simplifies code, (b) avoids issues with locking as ACPICA does
the serialization for us, (c) avoids the need to access the glocal softc, and
(d) avoids the O(n) loop required to search for a handle from the node queue.
|
| 1.4 |
| 27-Apr-2010 |
jruoho | branches: 1.4.2; 1.4.4;
Be consistent with the returned exception codes. Check for NULL pointers.
|
| 1.3 |
| 24-Apr-2010 |
jruoho | Add utility function acpi_get_node().
This retrieves a struct acpi_devnode from a handle. Since this requires
accessing the global softc, it is better to do it in one place alone. The
same goes for possible locking of the node-queue; it is better not to
publicize such a lock for generic device drivers.
|
| 1.2 |
| 15-Apr-2010 |
jruoho | Arrange some comments.
|
| 1.1 |
| 14-Apr-2010 |
jruoho | Reorganize the main file: add several missing prototypes, move the functions
around so that they appear in their logical order and place, etc. In
addition, split the utility functions to a separate file.
No functional change. Ok jmcneill@.
