一、提取AMDGopDriver.rom和vbios_1002_164c.bin

准备BIOS：ACB19103.bin，WIN系统操作
1、使用ubu处理bios，导出AMDGopDriver.efi
2、再使用edk2-BaseTools-win32-master工具把AMDGopDriver.efi 转为AMDGopDriver.rom
所在目录CMD：
.\EfiRom.exe -f 0x1002 -i 0xffff -e .\AMDGopDriver.efi
使用这个命令进行转换，1002是amd生厂商标识。-i 0xffff这个是产品id，这个随便四位十六进制都行（不需要写具体对应显卡编号），你就会得到AMDGopDriver.rom
3、PVE下操作，提取vbios_1002_164c.bin
nano vbios.c
gcc vbios.c -o vbios #需要安装gcc apt install gcc
./vbios #生成vbios_1002_164c.bin

vbios.c的源码
#include <stdint.h>
#include <stdio.h>
#include <stdlib.h>

int main(int argc, char** argv)
{
FILE* fp_vfct;
FILE* fp_vbios;
UEFI_ACPI_VFCT* pvfct;
char vbios_name[0x400];

if (!(fp_vfct = fopen("/sys/firmware/acpi/tables/VFCT", "r"))) {
    perror(argv[0]);
    return -1;
}

if (!(pvfct = malloc(sizeof(UEFI_ACPI_VFCT)))) {
    perror(argv[0]);
    return -1;
}

if (sizeof(UEFI_ACPI_VFCT) != fread(pvfct, 1, sizeof(UEFI_ACPI_VFCT), fp_vfct)) {
    fprintf(stderr, "%s: failed to read VFCT header!\n", argv[0]);
    return -1;
}

ULONG offset = pvfct->VBIOSImageOffset;
ULONG tbl_size = pvfct->SHeader.TableLength;

if (!(pvfct = realloc(pvfct, tbl_size))) {
    perror(argv[0]);
    return -1;
}

if (tbl_size - sizeof(UEFI_ACPI_VFCT) != fread(pvfct + 1, 1, tbl_size - sizeof(UEFI_ACPI_VFCT), fp_vfct)) {
    fprintf(stderr, "%s: failed to read VFCT body!\n", argv[0]);
    return -1;
}

fclose(fp_vfct);

while (offset < tbl_size) {
    GOP_VBIOS_CONTENT* vbios = (GOP_VBIOS_CONTENT*)((char*)pvfct + offset);
    VFCT_IMAGE_HEADER* vhdr = &vbios->VbiosHeader;

    if (!vhdr->ImageLength)
        break;

    snprintf(vbios_name, sizeof(vbios_name), "vbios_%x_%x.bin", vhdr->VendorID, vhdr->DeviceID);

    if (!(fp_vbios = fopen(vbios_name, "wb"))) {
        perror(argv[0]);
        return -1;
    }

    if (vhdr->ImageLength != fwrite(&vbios->VbiosContent, 1, vhdr->ImageLength, fp_vbios)) {
        fprintf(stderr, "%s: failed to dump vbios %x:%x\n", argv[0], vhdr->VendorID, vhdr->DeviceID);
        return -1;
    }

    fclose(fp_vbios);

    printf("dump vbios %x:%x to %s\n", vhdr->VendorID, vhdr->DeviceID, vbios_name);

    offset += sizeof(VFCT_IMAGE_HEADER);
    offset += vhdr->ImageLength;
}

return 0;

}

二、配置配置 GRUB

nano /etc/default/grub

修改为：
GRUB_CMDLINE_LINUX_DEFAULT=“quiet initcall_blacklist=sysfb_init”

update-grub
reboot

三、屏蔽驱动

nano /etc/modprobe.d/pve-blacklist.conf

在里面加入
blacklist nvidiafb
blacklist amdgpu
blacklist i915
blacklist snd_hda_intel
options vfio_iommu_type1 allow_unsafe_interrupts=1

最后更新initramfs
update-initramfs -u -k all
reboot

四、用MobaXterm将AMDGopDriver.rom和vbios_1002_164c.bin放到/usr/share/kvm/目录

五、配置win10虚拟机参数

nano /etc/pve/qemu-server/xxx.conf #xxx.conf的xxx是虚拟机编号
1、在cpu:hots 后面添加 ,hidden=1
2、hostpci1: 0000:05:00.0,pcie=1,x-vga=1 后面添加 ,romfile=vbios_1002_164c.bin
3、hostpci1: 0000:05:00.1,pcie=1 后面添加 ,romfile=AMDGopDriver.rom
Amd的核显（独显）编号和hdmi声卡编号一般挨着的，不一定是我这里05.00.0和05.00.1
虚拟机采用ovmf+i440fx或者q35都行，如果i440fx机型不需要pcie=1参数
显卡

#pve unraid核显直通多个efi多个rom合并转化成1个rom教程

.\EfiRom.exe -f 0xffff -i 0xffff -b .\vbios_1002_164c.bin -e .\AMDGopDriver.efi -o 5700u.rom

就这样一行命令简单合并转化出来1个rom，x-vga后面就挂一个5700u.rom就是了。如果不能直通，你把-f -i 后面编号改为真实编号比如：-f 0x1002 -i 0x164c

六，系统安装完后

先打RadeonResetBugFixService.exe补丁
下载解压放在c盘根目录，cmd管理员模式下运行 RadeonResetBugFixService.exe install
再安装AMD驱动。

七、过虚拟化文件

dpkg -l|grep kvm

dpkg -i pve-qemu-kvm_8.1.2-4_amd64_anti_detection20231105.deb

nano /etc/pve/qemu-server/101.conf

首行插入：
