Full amd64 support isn't really appropriate for most situations OpenWRT is deployed. Whereas x86-x32 seems extremely appropriate for these situations. As such enable x86-x32 support.
CONFIG_ARCH_MMAP_RND_COMPAT_BITS is required to follow along, otherwise the kernel build breaks. Signed-off-by: Elliott Mitchell <ehem+open...@m5p.com> --- I suggest OpenWRT should place some effort towards x86-x32. x86-x32 seems a rather superior generic target for OpenWRT. Only issue is it could be valuable to have at least minimal amd64 userland support alongside the x86-x32 version. Note, this simply enables kernel support. Until userspace building is added, this does almost nothing. --- target/linux/x86/64/config-5.15 | 1 - target/linux/x86/64/config-6.1 | 2 -- target/linux/x86/config-5.15 | 2 ++ target/linux/x86/config-6.1 | 3 +++ 4 files changed, 5 insertions(+), 3 deletions(-) diff --git a/target/linux/x86/64/config-5.15 b/target/linux/x86/64/config-5.15 index 28a4758e57..3c60769a85 100644 --- a/target/linux/x86/64/config-5.15 +++ b/target/linux/x86/64/config-5.15 @@ -503,7 +503,6 @@ CONFIG_X86_PM_TIMER=y # CONFIG_X86_POWERNOW_K8 is not set # CONFIG_X86_VSYSCALL_EMULATION is not set CONFIG_X86_X2APIC=y -# CONFIG_X86_X32 is not set CONFIG_XEN=y CONFIG_XENFS=y CONFIG_XEN_512GB=y diff --git a/target/linux/x86/64/config-6.1 b/target/linux/x86/64/config-6.1 index 66ae3e35f0..812fa0cfa6 100644 --- a/target/linux/x86/64/config-6.1 +++ b/target/linux/x86/64/config-6.1 @@ -558,8 +558,6 @@ CONFIG_X86_PM_TIMER=y # CONFIG_X86_POWERNOW_K8 is not set # CONFIG_X86_VSYSCALL_EMULATION is not set CONFIG_X86_X2APIC=y -# CONFIG_X86_X32 is not set -# CONFIG_X86_X32_ABI is not set CONFIG_XEN=y CONFIG_XENFS=y CONFIG_XEN_512GB=y diff --git a/target/linux/x86/config-5.15 b/target/linux/x86/config-5.15 index 71f06ad470..e93e46414a 100644 --- a/target/linux/x86/config-5.15 +++ b/target/linux/x86/config-5.15 @@ -13,6 +13,7 @@ CONFIG_ARCH_MAY_HAVE_PC_FDC=y CONFIG_ARCH_MHP_MEMMAP_ON_MEMORY_ENABLE=y CONFIG_ARCH_MIGHT_HAVE_PC_PARPORT=y CONFIG_ARCH_MIGHT_HAVE_PC_SERIO=y +CONFIG_ARCH_MMAP_RND_COMPAT_BITS=8 CONFIG_ARCH_NR_GPIO=512 CONFIG_ARCH_RANDOM=y CONFIG_ARCH_SELECT_MEMORY_MODEL=y @@ -429,6 +430,7 @@ CONFIG_X86_UP_IOAPIC=y CONFIG_X86_USE_PPRO_CHECKSUM=y CONFIG_X86_VERBOSE_BOOTUP=y CONFIG_X86_VMX_FEATURE_NAMES=y +CONFIG_X86_X32=y CONFIG_XZ_DEC_BCJ=y CONFIG_XZ_DEC_X86=y CONFIG_ZLIB_INFLATE=y diff --git a/target/linux/x86/config-6.1 b/target/linux/x86/config-6.1 index d6f8f6180b..a7affa9e56 100644 --- a/target/linux/x86/config-6.1 +++ b/target/linux/x86/config-6.1 @@ -14,6 +14,7 @@ CONFIG_ARCH_MAY_HAVE_PC_FDC=y CONFIG_ARCH_MHP_MEMMAP_ON_MEMORY_ENABLE=y CONFIG_ARCH_MIGHT_HAVE_PC_PARPORT=y CONFIG_ARCH_MIGHT_HAVE_PC_SERIO=y +CONFIG_ARCH_MMAP_RND_COMPAT_BITS=8 CONFIG_ARCH_NR_GPIO=512 CONFIG_ARCH_SELECT_MEMORY_MODEL=y CONFIG_ARCH_SPARSEMEM_ENABLE=y @@ -451,6 +452,8 @@ CONFIG_X86_UP_IOAPIC=y CONFIG_X86_USE_PPRO_CHECKSUM=y CONFIG_X86_VERBOSE_BOOTUP=y CONFIG_X86_VMX_FEATURE_NAMES=y +CONFIG_X86_X32=y +CONFIG_X86_X32_ABI=y CONFIG_XZ_DEC_BCJ=y CONFIG_XZ_DEC_X86=y CONFIG_ZLIB_INFLATE=y -- (\___(\___(\______ --=> 8-) EHM <=-- ______/)___/)___/) \BS ( | ehem+open...@m5p.com PGP 87145445 | ) / \_CS\ | _____ -O #include <stddisclaimer.h> O- _____ | / _/ 8A19\___\_|_/58D2 7E3D DDF4 7BA6 <-PGP-> 41D1 B375 37D0 8714\_|_/___/5445 -- (\___(\___(\______ --=> 8-) EHM <=-- ______/)___/)___/) \BS ( | ehem+sig...@m5p.com PGP 87145445 | ) / \_CS\ | _____ -O #include <stddisclaimer.h> O- _____ | / _/ 8A19\___\_|_/58D2 7E3D DDF4 7BA6 <-PGP-> 41D1 B375 37D0 8714\_|_/___/5445 _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
