It appears that the DSDT tables and the related ASL files are present for few boareds in Linux BIOS. If so how are other boards expected to provide the required DSDT table. Does it has to be taken care either by the kernel or intiramfs ? Is Linux BIOS ACPI 3.0 compatible ?
The reason I am looking at this is for supporting PCIe hotplug which looks for _OSC method. This has been specified in ACPI 3.0 spec.
which MB or chipset?
for MCP55, you may need to modify DSDT in seregenti_cheetah/8132/8111. you may need access to nvidia mcp55 NDA doc.
you may not look at your MB current DSDT in Normal BIOS. that dsdt is belonging to IBV ( Phoenix or AMI) instead of MB vendor.
