Re: Compaq Presario 2105US ACPI = NO MOUSE

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
