From: Yousong Zhou Date: Mon, 10 Oct 2016 13:11:18 +0000 (+0800) Subject: x86: 64: enable pci hotplug and acpipnp X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=d1000f81a895bd84d9aa19998cc4a468a5f68ea4;p=openwrt%2Fstaging%2Fblogic.git x86: 64: enable pci hotplug and acpipnp This will allow dynamically adding/removing at least virtio-net pci devices which are quite the norm in cloud environment with QEMU/KVM netdev_add bridge,id=wan2,br=br-wan,helper=/home/yousong/.usr/libexec/qemu-bridge-helper device_add virtio-net-pci,id=devwan2,netdev=wan2,mac=11:22:33:22:11:00 The config was formed by selecting target x86/64 first, then select CONFIG_HOTPLUG_PCI and CONFIG_HOTPLUG_PCI_ACPI with make kernel_menuconfig CONFIG_TARGET=subtarget The following text tries to explain how the current config was formed 1. CONFIG_PCI_LABEL and CONFIG_ATA_PIIX were removed because they were already enabled in x86 platform config 2. CONFIG_ATA_SFF was removed because it was enabled in generic config 3. CONFIG_NLS was removed because it will be selected by CONFIG_PCI_LABEL Signed-off-by: Yousong Zhou --- diff --git a/target/linux/x86/64/config-default b/target/linux/x86/64/config-default index 216db70aecb2..646e773e347e 100644 --- a/target/linux/x86/64/config-default +++ b/target/linux/x86/64/config-default @@ -40,9 +40,6 @@ CONFIG_ARCH_SUPPORTS_INT128=y CONFIG_ARCH_SUPPORTS_NUMA_BALANCING=y CONFIG_ARCH_USE_CMPXCHG_LOCKREF=y CONFIG_ARCH_WANT_BATCHED_UNMAP_TLB_FLUSH=y -CONFIG_ATA_SFF=y -CONFIG_ATA_PIIX=y -CONFIG_PATA_ATIIXP=y CONFIG_AUDIT_ARCH=y # CONFIG_BACKLIGHT_APPLE is not set CONFIG_BACKLIGHT_CLASS_DEVICE=y @@ -109,6 +106,12 @@ CONFIG_HAVE_MEMORY_PRESENT=y CONFIG_HAVE_VIRT_CPU_ACCOUNTING_GEN=y CONFIG_HID=y CONFIG_HID_BATTERY_STRENGTH=y +CONFIG_HOTPLUG_PCI=y +CONFIG_HOTPLUG_PCI_ACPI=y +# CONFIG_HOTPLUG_PCI_ACPI_IBM is not set +# CONFIG_HOTPLUG_PCI_CPCI is not set +# CONFIG_HOTPLUG_PCI_PCIE is not set +# CONFIG_HOTPLUG_PCI_SHPC is not set CONFIG_HPET=y CONFIG_HPET_MMAP=y # CONFIG_HP_ACCEL is not set @@ -156,7 +159,6 @@ CONFIG_MODULES_USE_ELF_RELA=y CONFIG_MUTEX_SPIN_ON_OWNER=y CONFIG_NEED_DMA_MAP_STATE=y CONFIG_NET_FLOW_LIMIT=y -CONFIG_NLS=y CONFIG_NR_CPUS=8 # CONFIG_NUMA is not set CONFIG_OUTPUT_FORMAT="elf64-x86-64" @@ -165,10 +167,10 @@ CONFIG_PARAVIRT_CLOCK=y # CONFIG_PARAVIRT_DEBUG is not set CONFIG_PARAVIRT_SPINLOCKS=y # CONFIG_PARAVIRT_TIME_ACCOUNTING is not set +CONFIG_PATA_ATIIXP=y CONFIG_PCIEAER=y CONFIG_PCIEPORTBUS=y CONFIG_PCI_BUS_ADDR_T_64BIT=y -CONFIG_PCI_LABEL=y # CONFIG_PCI_MMCONFIG is not set CONFIG_PGTABLE_LEVELS=4 CONFIG_PHYSICAL_ALIGN=0x1000000 @@ -241,9 +243,8 @@ CONFIG_X86_64=y CONFIG_X86_64_SMP=y CONFIG_X86_ACPI_CPUFREQ=y # CONFIG_X86_ACPI_CPUFREQ_CPB is not set -# CONFIG_X86_POWERNOW_K8 is not set -# CONFIG_X86_AMD_PLATFORM_DEVICE is not set CONFIG_X86_AMD_FREQ_SENSITIVITY=y +# CONFIG_X86_AMD_PLATFORM_DEVICE is not set CONFIG_X86_CMOV=y CONFIG_X86_CMPXCHG64=y CONFIG_X86_DEBUGCTLMSR=y @@ -255,6 +256,7 @@ CONFIG_X86_MINIMUM_CPU_FAMILY=64 # CONFIG_X86_PCC_CPUFREQ is not set # CONFIG_X86_PMEM_LEGACY is not set CONFIG_X86_PM_TIMER=y +# CONFIG_X86_POWERNOW_K8 is not set CONFIG_X86_TSC=y # CONFIG_X86_VSYSCALL_EMULATION is not set CONFIG_X86_X2APIC=y
