Description Marc-Christian Petersen 2004-12-07 12:35:23 UTC

Description of problem:

I just wanted to compile a 2.4.21-26.EL myself and saw that ACPI was
missing for arch/i386/config.in so I added it (simply including
drivers/acpi/Config.in). Compilation aborted due to missing
include/asm-i386/acpi.h. This is also valid for -25.EL, -20.EL and
probably earlier.

Is this intended?

Beside that, I found one circular dependency which is fixed by
attached patch and missing send_IPI_self when you compile with IOAPIC.
Find attached 2 patches which fixes this.

ciao, Marc

Thanks for the patches, Marc.  I seem to recall that there was some good
reason that we don't support ACPI in x86 configs, but I don't remember
the details.  I'll check into this at some point.

Comment 4 Rik van Riel 2004-12-08 02:34:49 UTC
Too many broken ACPI bioses, IIRC.

Also, the upstream ACPI x86 codebase didn't work on x86-64 and ia64 at
the time, so we took the ia64 ACPI codebase and added x86-64 bits to
it as we went along - slightly different from the x86 acpi codebase at
the time.

Comment 5 Ernie Petrides 2005-06-04 00:22:56 UTC
Okay, so the bottom line is that CONFIG_ACPI is not supported on x86.
