If you look at the DSDT attached there you can clearly see nodes defines which should lead to e.g. : /sys/bus/platform/devices/INT33C2:00 Showing up (which should then be bound by i2c-designware-platform).

It depends whether the BIOS has enabled those or not. If # cat /sys/bus/acpi/devices/INT33C2:00/status # cat /sys/bus/acpi/devices/INT33C3:00/status returns 0xf, then the device should be there, otherwise it is not. The "status" refers directly shat _STA() ACPI method returns. Note that the device could also be in PCI mode, in case lspci should show it. ^ permalink raw reply [flat|nested] 12+ messages in thread

Interesting. Marcos, can you give this a try please ? > The "status" refers directly shat _STA() ACPI method returns. Ok, so assuming that Marcos' testing shows it is not enabled, is there anything we can, could there be some ACPI call to enable these devs ? > Note that the device could also be in PCI mode, in case lspci should > show it.

The touchpad was working on Windows. Mika, I verified my BIOS configurations and there isn't any configuration to enable PCI devices. Do you beleive there is something about secure boot?

In your ACPI DSDT, there is also a device called PS2M that happens to to look like touch pad to me. For example it reports one of these _HIDs: Method (_HID, 0, NotSerialized) // _HID: Hardware ID { If (SYNA) { Return (0x190A2E4F) } If (ALPS) { Return (0x0713A906) } If (ELAN) { Return (0x08018416) } If (STLC) { Return (0x41C18C4E) } If (FOLT) { Return (0x01019419) } Return (0x060A2E4F) } Have you checked if any of these are present in /sys/bus/acpi/devices/*? > > > >>>>The "status" refers directly shat _STA() ACPI method returns. > >>>Ok, so assuming that Marcos' testing shows it is not enabled, > >>>is there anything we can, could there be some ACPI call to > >>>enable these devs ? > >>> > >>>>Note that the device could also be in PCI mode, in case lspci should > >>>>show it. > >>>Right, it does not show in lspci. > >OK.

Yes.

No, that is a guess because the windows drivers for this touchpad can do both ps/2 and i2c-hid, and we're sort of hoping that i2c-hid is attached, so that we don't need to reverse-engineer a new ps/2 protocol. But it looks like we are out of luck there, and we really need to figure out the ps/2 protocol. > In your ACPI DSDT, there is also a device called PS2M that happens to to > look like touch pad to me.

Well, given that the device name is PS2M I would expect it to be connected via serio using PS/2 protocol. ^ permalink raw reply [flat|nested] 12+ messages in thread
