Description Don Dutile 2009-08-18 17:52:25 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):

How reproducible:

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
Actual results:
PCI segment number incorrect; PCI dev's listed multiple times, etc.

Expected results:
Output that matches Fedora & upstream for proper interpretation.

Additional info:
Comment 1 Eduardo Habkost 2009-08-19 09:52:32 EDT
An update to latest iasl upstream version was proposed on bug #518209.
Comment 2 Eduardo Habkost 2009-09-09 17:51:10 EDT
iasl was updated to a newer upstream version, and iasl-20090123-1.el5 should fix this.
Comment 3 Lawrence Lim 2009-10-08 10:20:55 EDT
Moving to ON_QA so bug verification can begin.
