Greetings,
I've read your ASLs and figured out how psm0 fails to attach.
Both of the two ASLs have _CID (compat id) of MSE0 (read: psm0) as a package.
But, unfortunately, our current code does not handle such _CIDs.
So, for interim solution, I would propose following snippet of ASL.
Device (MSE0) // psm0/psmcpnp0
{
Name (_HID, EisaId ("SYN0105"))
Name (_CID, EisaId ("PNP0F13")) /// XXX - for now
Name (_CSR, Buffer (6)
{
0x23, 0x00, 0x10, 0x01, 0x79, 0x00
})
}
For long time solution, we have to modify the logic of acpi_isa_pnp_probe()
(defined in src/sys/dev/acpica/acpi.c) to support multiple _CID EisaIds.
I ever saw such patch before. (as long as my memory serves right)
# Mmm, takawata-san's work?
yours sincerely,
Taku
