Hi Michael,
What exactly indicates proper CMI support? I have a problem with acpi_hp(4)
on ProBook 645 G1 (infamous ``driver bug: Unable to set devclass (class: ppc
devname: (unknown))'' error), but it looks like all GUIDs listed inside the
`acpi_hp.c' are there:
$ cat /dev/wmistat0 | egrep '95F24279|5FB7F034|2D114B49'
{5FB7F034-2C63-45E9-BE91-3D44E2C707E4} 1 NO WMAA NO NO AA
{95F24279-4D7B-4334-9387-ACCDC67EF61C} 1 NO NO NO 0x80+ -
{2D114B49-2DFB-4130-B8FE-4A3C09E75133} 247 NO NO NO NO BC
Despite that "driver bug" message, /dev/hpcmi gets created, but reading it
yields just a bunch (247 of them, like the number above) of blank lines, and
issuing various sysctl(8) calls also does not work properly.
$ sysctl dev.acpi_hp.0.hdd_temperature
dev.acpi_hp.0.hdd_temperature: 4 <-- ??? what units are these?
# sysctl dev.acpi_hp.0.wlan_enabled=1
dev.acpi_hp.0.wlan_enabled: 0
sysctl: dev.acpi_hp.0.wlan_enabled=1: Interrupted system call
