Subject: Non-power related ACPI devices (help)
Date: Sun, 26 Jan 2003 18:03:19 -0500 [thread overview]
Message-ID: <3E346937.7080100@attbi.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 811 bytes --]
Hello,
I've installed Redhat 8.0 on a Compaq TC1000 tablet computer that I own.
I upgraded the kernel to 2.4.20+ the corresponding ACPI patch from
sourceforge. I have compiled the kernel with CONFIG_ACPI_DEBUG. The
TC1000 is fairly standard except for two devices. The first being the
touchscreen and the second some related buttons. I finally tracked down
the devices under windows and found that both are configured via ACPI.
I've attached the corresponding snippet from dsdt.
The first device is nothing more than a serial port on com1 (I believe).
The corresponding windows driver is a serial driver. The other one I am
not sure about.
My question is: how can i get these devices initialized via ACPI? If
someone could point me in the right direction, I'd greatly appreciate it.
Thanks,
Frank
