Custom kernel modules and patches for XPenology DSM 6.1 (kernel 3.10.102) on HP MicroServer Gen7 N54L (AMD Turion II).

• i2c-piix4.ko kernel module (https://github.com/fetzerch/hp-n54l-drivers)
• jc42.ko
• k10temp.ko
• w83795.ko

insmod i2c-piix4.ko
insmod k10temp.ko
modprobe i2c-piix4
modprobe k10temp

Patched kvm-amd.ko module enabling KVM/SVM virtualization on AMD CPUs.

The stock Synology kernel is compiled with CONFIG_CPU_SUP_AMD=n, which means boot_cpu_data.x86_vendor is never set to X86_VENDOR_AMD. As a result, the kernel's cpu_has_svm() check in virtext.h fails with "not amd" even on genuine AMD hardware, making it impossible to load kvm-amd and use hardware virtualization.

This module patches has_svm() in svm.c to check for AMD vendor directly via CPUID instruction, bypassing the broken boot_cpu_data. Works on any AMD CPU with SVM (AMD-V) support.

Use with synoKVM — a QEMU/libvirt/webvirtmgr package for Synology DSM.

insmod kvm-amd.ko
chmod 666 /dev/kvm

lsmod | grep kvm_amd
dmesg | grep -i "nested\|kvm"

Expected output: "Nested Virtualization enabled", "Nested Paging enabled"
