大家好，我正在把龙芯7A2000的独显芯片（貌似代号叫LG100?）内核驱动模块gsgpu移植到最新的主线内核上。目前的状态是可以通过编译但是还在调试之中（还没有调试通），大家有兴趣的可以一起加入进来，代码在github上 https://github.com/cl91/linux/tree/gsgpu 注意是gsgpu branch. 这个内核模块需要固件，我打包在 https://github.com/cl91/linux-gsgpu-archpkg gsgpu这个内核模块是8月底龙芯公司推送到loongnix的，可以比较好的支持背光和硬件加速（我就是因为天创者笔记本背光的问题才想到移植这个内核模块的），但是是基于4.19内核版本。Linux内核的DRM子系统从4.19到6.6rc2已经发生了比较大的变化，所以原厂的驱动代码有很多地方需要修改。很不幸7A2000的GPU部分是完全没有文档的，但是放出来的这个内核模块很显然是基于amdgpu大概2018年中的某个版本(估计就是v4.19)改的。大部分代码基本上是直接进行了字符串替换 amdgpu -> gsgpu。所以我个人猜测硬件本身是仿照早期的AMDGPU设计的，根据内核代码和loongnix里的libLLVM-8-loonggpu.so中的某些符号我猜测可能是基于ATI大概07年左右的R600架构设计的。（我个人不太认为是直接买AMD的软IP核，AMD貌似也不卖？摩尔线程是直接买的PowerVR的IP核，龙芯要是走拿来主义路线为啥不选择一个比较新的架构？所以这说不通。）貌似官方内部团队对这个内核模块也没有搞得很清楚，只是大概能跑通，代码质量比较一般。代码中AMDGPU-specific的部分貌似也没删干净，很多代码我猜测硬件是没有相应的功能的（看代码的时候有一个很好的判断到底那些代码是AMDGPU驱动直接字符串替换的还是龙芯团队后来修改的的方法，就是代码比较工整特别是注释的英语语法非常标准的地方一定是AMDGPU原来的代码，代码比较混乱特别是注释有大量语法错误的十有八九是龙芯团队后来加上去的 😆 ）。我本人对AMDGPU也不是非常熟悉，大家有什么想法请告诉我。在移植的过程中我整理了v4.19到v6.6rc2中DRM子系统的相关commit，放在github上（ https://github.com/cl91/linux-gsgpu-archpkg/blob/master/gsgpu-notes ），大家可以参考。

现在遇到的一个问题是加载完gsgpu内核驱动后系统马上就卡死了，没有机会做下一步的诊断。有没有人用过天创者上的USB串口界面调试过内核？可以告诉我一些经验不。更正一下我原帖里的猜测：看了更多的代码之后我比较倾向于认为7A2000独显是模仿AMD的GFX8架构设计的，这样就把时间拉到了2014年，和主流的差距小了一点（gfx8直到18年还属于主流架构，这样一看差距就更小了）。当然AMD显卡设计的特点是不同的IP block独立性比较高，所以不确定是不是所有的ip block都是gfx8时代的设计。

autistic-chad 可以在天创者笔记本bios界面上，打开串口，然后用双头usb线，连结到另一台计算机上，会识别成一个串口这个gsgpu，loongnix 上内核驱动和xserver-video-loongson代码可以找到一些，在uos上也可以找到gsgpu-dri的代码，目前大致上是这样。关于这个gpu，从收集的参数和实际性能看，我觉得更接近于r600，也就是amd 780e上集成的hd3000显卡核心，后续的gpgpu应该还会加上通用计算部分的支持。下面这个链接是收集到的信息，仅供参考龙芯新桥片7A2000的一些特性和主板图片视频资源 https://bbs.loongarch.org/d/99-7a2000

加 Telegram 群 loongson_users ，有技术问题可以在那儿尽情讨论（懂的人会更多）。这是重要的开发工作，我看到这些很感动，目前社区里开发者多少都不算多。祝你好运！如果有我搞过的东西，只要你问我和朋友们都会教你。

我也在移植 gsgpu，硬件系统是3A5000+7A2000，OS是 ArchLinux (6.3.0内核)。我遇到的问题是，ArchLinux中无法启动Gnome，我怀疑是因为缺少GPU驱动，所以就想把 loongnix 里的 gsgpu 移植到 ArchLinux。从 loognix 的源里下载了内核代码( http://pkg.loongnix.cn/loongnix/pool/main/l/linux/linux_4.19.190.8.6.orig.tar.gz ), 参考了 AMDGPU 驱动在 4.19 和 6.3 的差异，通过 dkms 编译成功了，但是在 insmod 后，应该触发 IH: XDMA trap 的地方却触发了 GPU 的 0x92(146) 异常。 GSGPU 异常后，系统还活着，所以能看 log，但是 0x92异常卡了我两个多月了，一直搞不定。希望能和大佬交流一下，wx: tsingkong

TSiNGKONG 噢噢我加你微信了我的微信号是 cl91tp

TSiNGKONG 我现在的status是虽然加载gsgpu模块后屏幕黑屏系统卡死，但sysrq还能用，所以用sysrq sync fs一下内核panic的log其实都是保留下来了，重启后能在journalctl里看到。这样我就能用printk大法定位问题。我修了几个小bug，但现在还没有到你说的那个gpu异常那儿。我现在的panic log是 Oct 02 23:13:04 mako kernel: [drm] Got VBIOS from mapped PCI ROM!

另外：由于我看过他们闭源 shader compiler 的反汇编等内容，具体驱动代码不适合我自己写，不过大家需要的话可以叫我（或者其他做过逆向的人）帮忙出些文档之类不破坏净室的事情。

TSiNGKONG 我现在遇到了和你类似的问题，就是gpu初始化的最后gsgpu_submit_job后gpu没法正确返回结果，而是ring xdma0 timeout. drm 的job scheduling从v4.19到v6.6变化还是比较大的，所以可能是我对这一块的理解有点问题。 Oct 05 16:54:59 mako kernel: [drm] gsgpu kernel modesetting enabled.

@xen0n @TSiNGKONG @杜比更新一下进度，现在之前两个bug貌似都解决了，xdma0 ring timeout 这个我把dma强行设置成32位的貌似就行了，我怀疑是硬件问题（或者固件的bug），导致显卡的xdma引擎没法dma到高于32位的地址。gfx fault这个问题是由于xdma的command ring中写入了错误的buffer地址导致的，在我的代码中我直接把相关的代码替换成amdgpu中(主要是vram_mgr 改用了新的DRM Buddy Allocator，这块变化比较大)，现在貌似已经调试通过了。现在的进度是驱动大体基本已经跑通了，驱动可以加载并且初始化硬件，但是在切换到fb的时候还有问题，是由于atomic mode setting相关的问题导致的，会在切换fb的时候出现BUG(): scheduling while atomic。atomic mode setting这个我也不大懂，所有在看相关的文档。我贴个最新的dmesg log [drm] gsgpu kernel modesetting enabled.

我正在把龙芯独显驱动的内核模块gsgpu移植到最新的主线内核上

autistic-chad

杜比噢如果龙芯公司有开源驱动的计划，那就好办了。这个 xf86-video-loongson 驱动代码我之前看了一下，貌似除了设置了一个用lasx/lsx写的专门的2D blitter以外，并没有比xserver自带的 xf86-video-modesetting 增加更多的加速功能（早期的图形卡是有专门的2D加速功能的，但gsgpu貌似没有相关的硬件单元，这个xf86-video-loongson除了这个lasx/lsx的blitter以外也没有别的2D加速功能）。我个人认为这个 lasx/lsx 写的 blitter 意义不是很大，因为 gcc 和 llvm 最近都合并了 lasx/lsx 相关的代码，随着编译器的进步编译器在编译 pixman 的时候应该可以直接生成使用了 lasx/lsx 的 blitter。即使编译器没法生成，这个优化也应该在 pixman 中做而不是在 xf86-video-loongson 中做（换句话说他这个 lasx/lsx 的 2D blitter 应该直接放到 pixman 中而不是在 xf86-video-loongson 中）。

现代的 Linux 图形驱动栈其实就两个部分，一个是内核模块，一个是用户空间的mesa （当然如果mesa调用了llvm来编译shader，那还依赖llvm）。xf86的驱动架构是为00年之前（可能最晚到05年左右吧）的显卡，特别是那些只有2D加速功能的显卡设计的，已经不适用现代3D显卡了。现代的 Linux 图形栈只需要一个通用的 xf86-video-modesetting 作为 Xorg 驱动就行了（Wayland已经彻底抛弃了 xf86-video 驱动架构，换句话说 Wayland 直接把 xf86-video-modesetting 的相关功能放在了 compositor 里）。

autistic-chad

杜比这个共享显存的问题，GSGPU 有一个module parameter叫 use_system_ram，可以关闭独显，采用共享显存。我在 7A2000 下测试过，但是有问题，跑不通，我过几天有空再试试。

autistic-chad

yetist 噢您这个是hibernate还是suspend？前者是关闭内存把状态写入磁盘的深度休眠，后者是内存还开着。如果是前者的话（您的log貌似表示您测试的是hibernate不是suspend），您能测试一下suspend不？如果是后者，是确定可以进入休眠（屏幕关闭，风扇关闭），但是按电源键唤醒后只能看到一个console光标，没法继续唤醒流程？我看了一下你提供的log，貌似到 11月 14 09:22:41 labook kernel: PM: hibernation: hibernation entry 这儿就结束了，没有唤醒记录。

我调试的时候只测试了suspend，hibernate还没测试过。如果您是hibernate有问题我周末在我的机器上尝试复现一下。我从来没用过hibernate（我一直都是suspend）所以没想到。

yetist

autistic-chad

嗯，挂起到内存没有问题，能回来的。
休眠到磁盘(需要用resume参数指定swap分区），能睡下去；按了电源键唤醒后，只能看到一个console光标在左上角，没法继续唤醒了，可能是显示出问题了。

911linux

linux-gsgpu-archpkg]$ makepkg

==> 错误：文件 install (xorg-server.install) 不存在，或者不是一个常规文件。

…

这是什么问题

autistic-chad

911linux 您需要cd 到 xorg-server 目录再执行 makepkg。xorg-server.install 文件是存在的，你可以检查一下你clone的 linux-gsgpu-archpkg repo 下有没有这个文件（在xorg-server目录下）。如果还是不行，可以直接安装 prebuilt 目录下的 xorg-server 包。

autistic-chad

yetist hibernate 这个比较复杂，因为系统hibernate之后是完全断电的。之后恢复其实某种程度上相当于是重启了。您试过在同样的笔记本上安装旧世界 loongnix，（开启gsgpu模块后）系统能否正常从hibernate 中恢复？我在调试gsgpu的过程中把天创者笔记本的固件搞坏了（话说它这个固件有bug吧，内核模块不应该能破坏固件，我怀疑应该是哪里映射到系统总线空间的固件页面本来要设置成只读的他们给设置成读写了），所以现在装不了新系统（现在的系统还能进入，但是每次启动的时候花屏，且无法进入固件，包括grub中选择Enter firmware setting也不行），没法和 loongnix 比较。我等周末有空的时候用现有的 Loongarchlinux 尝试复现这个hibernate bug。

话说有人知道天创者笔记本怎么联系厂家修固件不？或者有谁自己刷过？ @杜比

杜比

autistic-chad
https://github.com/loongson/Firmware
https://gitee.com/loongson/Firmware/tree/main/5000Series/Laptop/LM-A2207
这两个地址都可以下载固件和提issues

如果能进到固件的shell，有个spi命令，可以刷固件
如果无法进到shell，但系统启动正常，有个工具可用，
如果里面提供的二进制可执行文件不工作，可重新编译生成
https://github.com/MarsDoge/OsTools
https://gitee.com/bexsder/OsTools

休眠到磁盘上这个功能，在天创笔记本上偶尔无效，大概率反应很迟缓，往往要等到耐心极限，不只是固件的锅。
用上游内核，包括在pc机上，默认情况下，进入Hibernate很快，恢复也大多不正常。

记得之前有人提到过，从Hibernate恢复，唤醒链有一定的相关性，反应迟钝和等待部件加电状态相关，目前没有进一步的信息。

autistic-chad

杜比在刷了n次固件之后我貌似已经定位到破坏天创者笔记本固件的元凶了，原厂代码中有一行 *(int *)(0x80000e0010010444) |= 0x10;这一行在驱动初始化和从休眠中恢复的时候都会调用。我不知道这一行原本的目的到底是修改哪个寄存器，但这应该是龙芯工程师在调试的时候加上去的，然后发布最终代码的时候不小心没删掉。因为不同的系统中物理地址空间中的io映射是不一样的，而这个地址在天创者笔记本上正好对应的是固件映射在物理地址空间中的页面（我升级了16G内存和无线网卡，没升级的机器可能不对应这个页面），所以这行代码就破坏了天创者笔记本的固件。这一点经过我刷了n多次固件后证实，只要执行这一行代码，固件必然挂掉。

@yetist 我已经push了相关的fix（就是直接把这行删掉，我大不清楚龙芯工程师原本的意图是什么，不过去掉了貌似没啥影响）到我的github repo。我正在打包中，马上上传prebuilt packages。

杜比

autistic-chad 周末在天创者笔记本上测试了一下，使用archlinux的livecd ver 10.10安装，整理如下：

livecd可以启动引导到桌面环境，不需要nomodeset开关选项，loongson的drm驱动正常工作
安装过程中，进入分区选择步骤黑屏，应该是个提示信息，按回车，可以显示分区方案
配置lightdm为登录管理器，可以登录xfce4和mate，plasma白屏
使用sddm登录管理器时，白屏，无法继续
使用 pacman -U 安装 gsgpu 相关软件包，修改/boot/grub/grub.conf，添加gsgpu引导选项
使用gsgpu驱动可以进入系统，可以使用lightdm和deepin的登录管理器，sddm黑屏
使用gsgpu驱动可以进入mate和xfce4，plasma黑屏
在xfce4环境下，启动plasma配置程序黑屏
从表现的现象推断，涉及opengl的模块黑屏，转换成软件模拟，可以工作
在debian上也做了相关测试，用楼主的patch，编译内核，可以工作

淡炒番茄

这个代码真厉害。

autistic-chad

淡炒番茄正式发布的内核模块能出现这行代码某种程度上也反映出龙芯相关团队内部的开发管理流程有很大问题，这种调试代码能check in到repo而且能通过code review本身就是很严重的管理体系上的疏漏（我甚至有理由怀疑他们code review估计就是走个形式，聊胜于无），或者也可能是为了发布进度赶工过于着急。所以为了代码质量，我还是呼吁龙芯公司早日开源用户空间的3D驱动，让社区一起改进代码吧。

当然这其实也是固件本身的一个bug，这个页面需要设置成只读它给设置成可读写了。原则上说内核不管做啥（除了直接访问spi之外）都不应该能破坏固件。

ghw

autistic-chad 😆 群里有个大佬测试3A6000的固件输出里有3A5000字样

autistic-chad

ghw 哈哈估计是赶工没注意，忘了改了，最先关注的肯定是功能上的实现，这种字符串错误优先级肯定比较低。其实也没有办法，和国外fabless大厂相比龙芯毕竟非常缺钱和缺人力，所以其实最好的办法是开源，让社区一起搞。

淡炒番茄

其实固件是没法开源的，外面的人也没法搞。像Intel也是FSP的二进制发布到社区，然后可以开发Uboot，coreboot，Linuxboot等。

yetist

杜比

出现黑屏现象，主要是3D用不了，跑glxgears即可验证。

autistic-chad

杜比 yetist 对出现黑屏的原因是没有用户空间的3D驱动，所以桌面环境只要用了OpenGL或Vulkan必然黑屏。2D软件渲染是可用的。这个只能等龙芯开源3D驱动了，大家先用2D桌面环境吧（话说7A2000显卡的3D性能估计也带不动3D桌面，当然可能简单的特效估计还行）。loongson DRM 也能用是因为我给 xserver 打的补丁 https://github.com/loongarchlinux/extra/pull/3 同时修复了 xf86-video-modesetting 在 loongson DRM driver 和在 gsgpu 下的适配问题。这个补丁我今晚就给上游推送，最近有点忙我忘了 😅 。

autistic-chad

新增 gsgpu-devel branch，track 上游最新的主线内核 (现在是 v6.7-rc2)，所有的后续开发工作也会在 gsgpu-devel branch进行。gsgpu branch 是稳定版 (v6.6 内核)，除了大的bug fix以外不会随意改动，在 v6.7 发布后我会把 gsgpu branch 指向到时候最新的稳定版。

ghw

autistic-chad 😄 小声哔哔，能顺便把7A2000的网卡合并进来嘛 😅 😅 😅

autistic-chad

ghw 我的天创者笔记本网卡是自动就识别了，不需要out of tree驱动？你说的这个要移植的驱动叫什么？

ghw

autistic-chad
天创者主板上还有个自带网卡
