Red Hat Bugzilla – Bug 518109
iasl doesn't properly decode DMAR tables
Last modified: 2010-03-30 04:19:48 EDT
Description of problem:
The current version of iasl in RHEL5.4 is very old (circa: 2006).
Fedora's latest version is sprint '09.
Updated version needed to properly decode DMAR tables
extracted from /sys/firmware/acpi/tables/DMAR.
Current decode is wrong in a couple places, so it challenges
the user to know whether the ACPI DMAR tables are correct or not.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Extract a DMAR table from /sys/firmware/acpi/tables/DMAR
(may have to use F11 to do so if kernel support not added yet).
2. run 'iasl -d DMAR.raw' where DMAR.raw was geneated by
cat /sys/firmware/acpi/tables/DMAR > DMAR.raw
PCI segment number incorrect; PCI dev's listed multiple times, etc.
Output that matches Fedora & upstream for proper interpretation.
An update to latest iasl upstream version was proposed on bug #518209.
iasl was updated to a newer upstream version, and iasl-20090123-1.el5 should fix this.
Moving to ON_QA so bug verification can begin.
