	Add an NVMe drive and be more conservative with hotplug-capable PCIe ports. QEMU treats everything as hotpluggable by default, so devices can be added at runtime. However, this leads to unrealistic resource allocations with PCIEXP_HOTPLUG enabled. Tested recent allocator changes with QEMU/Q35 config and: $ make qemu QEMU_EXTRA_CFGS=util/qemu/q35-alpine.cfg Change-Id: I23746b642329356c6767b04ec177cd9411e3adb9 Signed-off-by: Nico Huber <nico.h@gmx.de> Reviewed-on: https://review.coreboot.org/c/coreboot/+/67026 Reviewed-by: Felix Singer <service+coreboot-gerrit@felixsinger.de> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Lean Sheng Tan <sheng.tan@9elements.com>
2021-03-12	util/qemu: Add additional config file for QEMU/Q35	Nico Huber
	The `q35-alpine.cfg` adds a lot of PCIe devices to resemble the topology inside an Intel Alpine Ridge Thunderbolt controller. By no means could this be detected as such a controller. But having a real-world example of such a topology can help to test the allocator and other algorithms on a deeper tree. It adds two levels of PCIe switches (`alpine-root` and `alpine-1`), and two endpoints (a `pci-testdev` and an xHCI controller). It can be added to the default `q35-base.cfg` config, e.g. with: $ make qemu QEMU_EXTRA_CFGS=util/qemu/q35-alpine.cfg Change-Id: Ieab09c5b67a5aafa986e7d68a6c1a974530408b0 Signed-off-by: Nico Huber <nico.h@gmx.de> Reviewed-on: https://review.coreboot.org/c/coreboot/+/51329 Reviewed-by: Arthur Heymans <arthur@aheymans.xyz> Reviewed-by: Angel Pons <th3fanbus@gmail.com> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
