Hi, Keir,

 

This is a new version of the patch, it works on changeset 17243. None of the header files under xen/include/acpi has changed this time, and all ported functions are from Linux 2.6.24.2.

 

Best regards,

Huacai Chen

I’ve done a more comprehensive update of the Xen ACPI header files (upgraded to Linux 2.6.24). Please re-work your patch against changeset 17231 in xen-unstable staging tree. Avoid changing any header files under xen/include/acpi/ unless you have good reason. Where you take new files from Linux, please use Linux 2.6.24 or newer.

 Thanks,
 Keir

Hi, all,
 
Some ACPI registers may be in System_Memory but not System_IO space, For these machines S3 fails since current Xen use I/O instructions (e.g. inb(), outb(), etc.) to access ACPI registers. The patch attached fix the bug by adding GAS (generic address structure) support ported from Linux, which should also benefit later ACPI activity within Xen.
