你这个armbian是在哪下载的?官方支持了?找一下这个am40.dtb的原始dts文件。

还有 CRRC 之前那个帖子的原地址现在无效了,你给个新的地址,能看到那个很多设备下载的网站,我下个固件。

我没找到dts,只有这两个dtb,地址:https://musetransfer.com/s/6jq15dl9p
不知为何,我用线刷工具写入emmc,不能启动(HDMI不显示,是否真实启动未知),写入TF卡可正常启动。

没有源码,不知道这个u-boot里是否支持emmc启动。

有相关源码或者可用的ubuntu/debian/armbian/openwrt等系统没,如果有的话新开个帖子讨论吧,不要把不同的机器混在一个帖子里讨论。

rk3399-smart-am40-oc.dtb 的cpu频率高些,不过还是没检测出A72的CPU

不知道咋回事呢,但是a53显示的频率是不对的,显示了a72的频率。群友贴他板子(不同板子,同rk3399)如下

官方固件不是zip,是个img文件。我解压出来了boot.img和uboot.img,但是没工具进一步解包。我到手的am40就是刷了原生android的,不是原始固件所以没提取。
解压出来的uboot和boot我上传到了github:https://github.com/dos7lo/am40
原始固件和两个文件也上传到了百度网盘。https://pan.baidu.com/s/1_Nsm6_UVIRlIk50A3pAOEA?pwd=mc6a
提取码:mc6a
补充谷歌网盘:https://drive.google.com/drive/folders/1M5133bfxPSKqx3iJmEzvsDtwFk1Tk22u?usp=sharing

这种反编译的不是正常dts,只能小改微调使用,不是源文件。

异构核心---升级至7.2-15之后,可以在web上手动绑核,PVE官方已经支持绑核
kvm目前不自适应异构核心CPU,例如RK3399,属于4小核,2大核组成的6核。

当KVM在初始化虚拟机的时候,不知道给虚拟机哪个线程。会出现下面报错
kvm: kvm_init_vcpu: kvm_arch_init_vcpu failed (0): Invalid argument

所以当你的CPU是异构的情况时,你必须在虚拟机启动的时候,手动绑定线程。

如下:
#将虚拟机配置导出为kvm命令
qm showcmd 100 >100.cmd
#添加指定权限
chmod +x 100.cmd
#手动绑定0-3cpu到这个虚拟机
taskset -c 0-3 100.cmd

当然,可以修改PVE底层代码,完成自动化。

编辑/usr/share/perl5/PVE/QemuServer.pm 文件

在下面位置添加#号之间的内容,可以通过搜索kvm_binary; 快速定位

my $use_old_bios_files = undef;
($use_old_bios_files, $machine_type) = qemu_use_old_bios_files($machine_type);
#添加
if (defined($conf->{cpu_taskset})) {
push @$cmd, 'taskset', '-c', $conf->{cpu_taskset};
}

push @$cmd, $kvm_binary;

在下面位置添加#号内容,可以通过搜索$cicustom_fmt 快速定位。

meta => {
    type => 'string',
    format => $meta_info_fmt,
    description => "Some (read-only) meta-information about this guest.",
    optional => 1,
},

#######################
cpu_taskset => {
optional => 1,
type => 'string',
description => "CPU pinning config.",
verbose_description => "When specified VM will be launched with cpuset -c {cpu_taskset} kvm ...\n"
."No argument test is performed so please make sure the value matches VM cpu total thread count.\n"
."This is required when VM is sensitive to host context switching (e.g. gaming),"
." or when host is not SMP so VM thread could be switched to a different CPU architecture (e.g. big.LITTLE for ARM).",
},
#################################
};

my $cicustom_fmt = {
meta => {
type => 'string',
optional => 1,
修改完成之后,重启pve服务

systemctl restart pvedaemon

感谢大佬的贡献!
大佬有加为armbian加上 Panfrost 驱动支持的计划没?
目前Arm 官方只提供安卓平台Mali 系列GPU的支持。有国外大神开源Arm linux Mali 系列GPU的驱动 Panfrost ,可用于加速计算、视频编解码、界面渲染等操作。

大佬您好,我有一个AM60的板子,只有板载的android13系统,可以提取反编译dts。请问我想适配一下armbian系统,需要准备哪些文件呢?如何修改反编译的dts呢?
