Merged long time ago. ---------------------------------------- Bug #2002: acpica upgrade to 20110211 (tentative) http://bugs.dragonflybsd.org/issues/2002 Author: Magliano Andrea Status: Closed Priority: Normal Assignee: Category: Target version: Hi all, the background: using dfly on an old laptop with not fully acpi compliant chipset caused kernel panic, due to: - double free in /sys/contrib/dev/acpica-unix/namespace/nspredef.c - null pointer exception in AcpiReadBitRegister (fixed with commit 744f6957d487e57f1e5e6ed66c85a5601f48804f) As the first problem has been already fixed in a later acpica release (found in http://git.moblin.org/cgit.cgi/acpica/commit/?id=235329a8f3056c9a7553e3a0a5ad43213384312b), the only reasonable thing to me to do was an acpica release upgrade. So i dared bringing in acpica 20110211: https://github.com/randy1/DragonFlyBSD/commit/ea7ae20415c0af1882c4bcb40167443f4fae9d12 It's a big patch, but it's just a bring in of acpica-unix-20110211.tar.gz with the least number of modifications to compile. It's still not usable anyway: - absurd temp values reported (was the same in fbsd 6.3, seen in forums) - on that laptop two GPEs cause an interrupt storm, slowing down the system Changes in /sys/dev/acpi are kept at a minimum to adapt to the new api (btw simpler, but more fine grained), except new AcpiSetupGpeForWake(), for what i followed fbsd 8.0 code As i'm new to dfly, acpica, git(hub) i'm not sure if: - i brought in all necessary stuff from tarball - all things i brought in are really necessary - my modifications in /sys/dev/acpi dir are meaningful at all That's why i would be grateful if someone experienced could review the patch and give feedback. Further, patch unrelated feedback (coding style, git usage, ...) is highly appreciated too.
