* asmc: add MMIO backend for T2 MacsAbdelkader Boudih2026-06-031-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | T2 Macs (2018+) expose the SMC via memory-mapped registers instead of I/O ports. Add asmcmmio.c/asmcmmio.h implementing the MMIO transport: key read/write, getinfo, getbyindex, and a poll-based wait with exponential backoff. The driver probes for MMIO at attach time by checking the LDKN firmware version key; if MMIO is available it is used, otherwise the standard I/O port backend is used. T2 fan speeds use IEEE 754 floats instead of fpe2 fixed-point. Per-fan manual mode uses F%dMd keys instead of the FS! bitmask. Battery charge limit is exposed via dev.asmc.N.battery_charge_limit.

* asmc: rename wol sysctl to auto_poweronAbdelkader Boudih2026-05-041-1/+3
| | | | | | | | | | | Older SMC firmware exposed AUPO as a Wake-on-LAN control. On updated firmware, the key controls automatic power-on when AC power is restored after a power loss; WoL is handled by the GBE controller instead. Rename the sysctl to reflect the current semantics. No compatibility alias is provided as the sysctl has not appeared in any release.

| | | | | | | | | | | | | | | | | | | | | Probe SMC keys at attach time to detect hardware capabilities, supporting all Intel Apple machines without per-model entries. Sensors are discovered by scanning sorted SMC key ranges for known prefixes and types. Capabilities such as SMS, fan safe speed, and ambient light are detected by key presence. A global key description table provides human-readable names for well-known temperature sensors.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Apple SMCs contain numerous undocumented voltage, current, power, and ambient light sensors. This change adds automatic detection and registration of these sensors as sysctls.

Tested on: - Mac Mini 5,1 (2011) running FreeBSD 15.0-RELEASE - 54 sensors auto-detected and exposed via sysctl - All sensor types verified with multimeter readings - Fixed-point conversions validated against known values - Memory management tested (malloc/free on detach) Reviewed by: adrian Differential Revision: https://reviews.freebsd.org/D55807

* asmc: add support for MacBookPro13,1Marcus Gartner2026-04-161-0/+18
| | | | | | | | | | | | | | | This commit adds support for the MacBookPro13,1 (late 2016, 13-inch). The SMC keys were collected from https://logi.wiki/index.php/SMC_Sensor_Codes. Two temperature keys are omitted because they fail to be read: TI0P (IO Proximity) and Ta0P (Ambient Air). Note that the with this model the `dev.asmc.0.fan.0.minspeed` setting only applies when the fans have been activated by the system. In my testing, the fans did not spin up until CPU temperatures hit about 80C. At lower temperatures, the fans will happily ignore the minimum speed and remain at 0 rpm.

* asmc: add raw SMC key read/write interfaceAbdelkader Boudih2026-04-151-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a debugging interface to read and write arbitrary Apple SMC keys by name through sysctl, enabling hardware exploration and control of undocumented features. The interface provides four sysctls under dev.asmc.0.raw.*: - key - Set the 4-character SMC key name (e.g., "AUPO") - value - Read/write key value as a hex string - len - Auto-detected key value length (can be overridden) - type - Read-only 4-character type string (e.g., "ui8", "flt") Implementation includes a new asmc_key_getinfo() function using SMC command 0x13 to query key metadata. The interface automatically detects key lengths and types, uses hex string encoding for arbitrary binary values, and is safe for concurrent access via CTLFLAG_NEEDGIANT. This interface was essential for discovering that the AUPO key enables Wake-on-LAN from S5 state, and for mapping all 297 SMC keys on Mac Mini 5,1.

| | | | | | | | | | | | | | | | The SMC firmware revision can prove helpful when determining why the behavior of a given controller varies from the maintainers' expected behavior. This should be a sysctl (eventually), but for now dumping out the information via `device_printf(..)` suffices, given that only one asmc(4) compatible device can exist in an Apple platform at any given point in time. This will become a sysctl in the future after additional improvements are incorporated from OpenBSD and NetBSD.

* asmc: add Wake-on-LAN control via sysctlAbdelkader Boudih2026-02-251-0/+5
| | | | | | | | | | | | | | | | | Apple Mac systems support Wake-on-LAN from powered-off state (S5/G2) via the AUPO SMC key. This change adds a convenience sysctl, `dev.asmc.0.wol`. This can be disabled if set to 0 and enabled if set to 1. The AUPO key is volatile and resets to 0x00 on every boot, so WoL must be manually enabled before each shutdown to work from powered-off state. Users need to run: `sysctl dev.asmc.0.wol=1` before shutting down the system. The sysctl is best set to persist in `/etc/sysctl.conf`.
