The Arm ACPI code relied on PCI_NETBSD_CONFIGURE to configure devices that were not enabled by system firmware. This is not safe to do unless the firmware explicitly permits it using a device specific method defined in the PCI firmware spec. Introduce a new PCI resource manager that discovers what has already been configured by firmware and allocates from the remaining space. This will ensure that devices setup by firmware are untouched and only will program BARs of devices that are not enabled at boot time. The current implementation assumes that the parent PCI-PCI bridge's are already configured. A worthwhile improvement in the future would be to support programming windows for bridges that are not fully configured. @ text @# $NetBSD: std.generic64,v 1.19 2022/06/25 13:24:35 jmcneill Exp $ # # generic NetBSD/evbarm64 with FDT support machine evbarm aarch64 include "conf/std" include "arch/aarch64/conf/std.aarch64" # arch standard options # Architecture options options AARCH64 options ACPI_REDUCED_HW options ARM_GENERIC_TODR options ARM_INTR_IMPL="" options DRAM_BLOCKS=256 options EVBARM_BOARDTYPE="FDT" options FDT # Flattened Device Tree support options FPU_VFP options MODULAR options MODULAR_DEFAULT_AUTOLOAD options PCI_NETBSD_CONFIGURE options PCI_RESOURCE options PCI_SMCCC # Arm PCI Conf Access Firmware Interface options _ARM32_NEED_BUS_DMA_BOUNCE options __HAVE_GENERIC_CPU_INITCLOCKS options __HAVE_PCI_CONF_HOOK options __HAVE_PCI_MSI_MSIX options __BUS_SPACE_HAS_PROBING_METHODS options __BUS_SPACE_HAS_STREAM_METHODS # XXXNH not yet #options __HAVE_CPU_UAREA_ALLOC_IDLELWP makeoptions BOARDMKFRAG="${THISARM}/conf/mk.generic64" # initrd support options MEMORY_DISK_HOOKS options MEMORY_DISK_DYNAMIC pseudo-device md # General options options CHILD_MAX=1024 # 160 is too few options OPEN_MAX=1024 # 128 is too few @ 1.19 log @Remove GIC_SPLFUNCS. @ text @d1 1 a1 1 # $NetBSD: std.generic64,v 1.18 2021/10/31 12:34:48 jmcneill Exp $ d22 1 @ 1.18 log @Disable GIC_SPLFUNCS (still crashy) @ text @d1 1 a1 1 # $NetBSD: std.generic64,v 1.17 2021/10/30 19:28:40 jmcneill Exp $ a18 1 #options GIC_SPLFUNCS # Experimental @ 1.17 log @Enable GIC_SPLFUNCS again.
