From 9560b6dea8e48f24ba04ad190edaae62354c1c11 Mon Sep 17 00:00:00 2001 From: Tomas Hruby Date: Thu, 2 Sep 2010 15:44:04 +0000 Subject: [PATCH] ACPI driver - 99% of the code is Intel's ACPICA. The license is compliant with BSD and GNU and virtually all systems that use ACPI use this code, For instance it is part of the Linux kernel. - The only minix specific files are acpi.c osminixxf.c platform/acminix.h and include/minix/acpi.h - At the moment the driver does not register interrupt hooks which I believe is mainly for handling PnP, events like "battery level is low" and power management. Should not be difficult to add it if need be. - The interface to the outside world is virtually non-existent except a trivial message based service for PCI driver to query which device is connected to what IRQ line. This will evolve as more components start using this driver. VM, Scheduler and IOMMU are the possible users right now. - because of dependency on a native 64bit (long long, part of c99) it is compiled only with a gnu-like compilers which in case of Minix includes gcc llvm-gcc and clang --- drivers/Makefile | 6 +- drivers/acpi/Makefile | 153 ++ drivers/acpi/acpi.c | 279 ++++ drivers/acpi/dispatcher/dsfield.c | 776 ++++++++++
