From c318bef76206c2ecb6016e8e68c4ac6ff9a4c8cb Mon Sep 17 00:00:00 2001 From: Julia Suvorova Date: Fri, 12 Nov 2021 06:08:54 -0500 Subject: hw/acpi/ich9: Add compat prop to keep HPC bit set for 6.1 machine type To solve issues [1-2] the Hot Plug Capable bit in PCIe Slots will be turned on, while the switch to ACPI Hot-plug will be done in the DSDT table. Introducing 'x-keep-native-hpc' property disables the HPC bit only in 6.1 and as a result keeps the forced 'reserve-io' on pcie-root-ports in 6.1 too.
