Newbie looking to try latest ACPI support...

I recently got a Toshiba Satellite 1115-S103 laptop which only has ACPI power management. Obviously the drivers in RH 8.0 (kernel version 2.4.18-18.8) don't do anything useful.

I was hoping to try out a newer development driver but I'm not sure if it's best to just try the acpi-20020918 for which 2.4.18 patches are available, or should I not bother with those and go with the latest drivers for 2.4.20, which obviously means upgrading to that kernel???

I'd say upgrade to that kernel. :)

I ended up upgrading my kernel to 2.4.20 and applied the acpi-20021205-2.4.20.diff.

I turned off APM and chose the following ACPI related kernel config options:

# CONFIG_HOTPLUG_PCI_ACPI is not set
CONFIG_ACPI=y
CONFIG_ACPI_DEBUG=y
CONFIG_ACPI_BUSMGR=m
CONFIG_ACPI_SYS=m
CONFIG_ACPI_CPU=m
CONFIG_ACPI_BUTTON=m
CONFIG_ACPI_AC=m
CONFIG_ACPI_EC=m
CONFIG_ACPI_CMBATT=m
CONFIG_ACPI_THERMAL=m

For some reason no modules were installed in /lib/modules/2.4.20:

[root@toshiba1115 linux-2.4.20]# find /lib/modules/2.4.20 -name '*acpi*' -print [root@toshiba1115 linux-2.4.20]#

Just to make sure I started over and did it again. Same thing. I'm sure I'm missing just one simple step.

did you run `make modules_install'?

Of course.
I just ran it again just now for about the tenth time and still no go. Here's the relavant part of the output from "make modules_install":

make[1]: Entering directory `/usr/src/linux-2.4.20/drivers'^M make -C acpi modules_install^M
make[2]: Entering directory /usr/src/linux-2.4.20/drivers/acpi'^M make[2]: Nothing to be done for modules_install'.^M make[2]: Leaving directory `/usr/src/linux-2.4.20/drivers/acpi'^M make -C atm modules_install^M

Yet that directory does seem to contain the files:

[root@toshiba1115 linux-2.4.20]# ls drivers/acpi/

Config.in       battery.c    executer   ospm         resources

acpi_ksyms.o    events       osl.c      processor.c  utils.c

[root@toshiba1115 linux-2.4.20]#

Maybe I'll just wipe out that directory and start all over with a fresh copy of the kernel sources and acpi patch...

I did that my starting with a clean 2.4.20 kernel, applied the acpi-20021205-2.4.20.diff patches, reconfigured my kernel, did the correct kernel build procedure. Everything worked without apparent error and I do have files in the acpi driver directory:

[root@toshiba1115 pcmcia-cs-3.2.3]# ls /lib/modules/2.4.20/kernel/drivers/acpi/ ac.o battery.o button.o fan.o processor.o thermal.o toshiba_acpi.o

While updating my PCMCIA driver I saw the following errors:

make[2]: Leaving directory `/usr/src/pcmcia-cs-3.2.3/etc/cis'
-> Updating client scripts in /etc/pcmcia
-> Running depmod...

Is this anything to worry about??

Still no joy...

Even tough everything "seemed" to compile and install I can't load my ACPI modules. Any time I try I get stuff like this:

[root@toshiba1115 root]# insmod battery 2>&1 | more /lib/modules/2.4.20/kernel/drivers/acpi/battery.o: unresolved symbol acpi_get_handle_R2bfeb410 /lib/modules/2.4.20/kernel/drivers/acpi/battery.o: unresolved symbol acpi_ut_exit_R4403d3ee /lib/modules/2.4.20/kernel/drivers/acpi/battery.o: unresolved symbol acpi_os_free_R43b9bbb4 /lib/modules/2.4.20/kernel/drivers/acpi/battery.o: unresolved symbol acpi_extract_package_R06f4a82a /lib/modules/2.4.20/kernel/drivers/acpi/battery.o: unresolved symbol acpi_ut_trace_R8d457864 /lib/modules/2.4.20/kernel/drivers/acpi/battery.o: unresolved symbol acpi_remove_notify_handler_R2bb55d6e /lib/modules/2.4.20/kernel/drivers/acpi/battery.o: unresolved symbol acpi_ut_value_exit_Rdcbde352 /lib/modules/2.4.20/kernel/drivers/acpi/battery.o: unresolved symbol acpi_evaluate_object_R39f1a5dc /lib/modules/2.4.20/kernel/drivers/acpi/battery.o: unresolved symbol acpi_bus_get_status_Redecd2bd /lib/modules/2.4.20/kernel/drivers/acpi/battery.o: unresolved symbol acpi_ut_debug_print_Rac38b5ca /lib/modules/2.4.20/kernel/drivers/acpi/battery.o: unresolved symbol acpi_bus_generate_event_R03047640 ...and so on...

I even logged the output of "make modules" and checked the acpi stuff and there is no sign of any kinds of errors...
