Instead, hold the lock while we copy the contents to a stack-based Vector then iterate on it without any locking. Because we rely on heap allocations, we need to propagate errors back in case of OOM condition, therefore, both PCI::enumerate API function and PCI::Access::add_host_controller_and_enumerate_attached_devices use now a ErrorOr<void> return value to propagate errors. OOM Error can only occur when enumerating the m_device_identifiers vector under a spinlock and trying to expand the temporary Vector which will be used locklessly to actually iterate over the PCI::DeviceIdentifiers objects. |
