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.

@yetist gsgpu-devel 已经 rebase 到 Linux v6.7-rc7

yetist

autistic-chad

好，安排

autistic-chad

yetist gsgpu-devel branch 已经更新到v6.8-rc2, 主要是drm scheduler的几个比较trivial的API变化. gsgpu branch 更新到 v6.7 正式版.

autistic-chad

@yetist @杜比更新一个软件3D渲染的进度，软件3D渲染用softpipe是可以跑的，默认的llvmpipe不知道为什么不能跑（表现在glxgears直接就是黑屏，貌似完全没发生渲染操作，因为我调用glClear()是可以给绘图缓冲区一个solid color fill的，但是任何渲染操作都是noop）。所以需要设置环境变量 export GALLIUM_DRIVER=softpipe （当然最好不要直接放在.bashrc里，因为有的程序打开3d后会很慢，softpipe的性能实在是太弱了）。在x11 (glx, egl), wayland (egl), 和没有显示管理器的裸的 drm+egl 环境下都能跑(drm+egl 可以用kmscube测试, egl 下可以用 eglgears 测试)。我拍了两个小视频, glxgears (x11), kmscube (drm+egl)。

当然softpipe比较慢，所以跑3D游戏那不现实。现在我主要想搞清楚为什么 llvmpipe 没法渲染。

环境变量确实有效，可以解决安装程序中部分界面黑屏的问题。 😄

会不会是由于 mesa 缺补丁，导致无法匹配合适的 driver，最终用了 noop driver 呢？

开启 CONFIG_PWM_LS=m 之后，编译会报错：

yetist 您用的是 gsgpu-devel 还是 gsgpu branch？v6.8-rc2 要用 gsgpu-devel。这一行在 gsgpu-devel 已经改成了 pwm->chip.id = -1; gsgpu-devel的HEAD的commit id是b079a856d7b07672c28c2cfb3493de5ab68b9210

autistic-chad

@yetist gsgpu-devel branch 已经 rebase 到最新的 v6.9-rc3。v6.8到v6.9居然只有一个非常trivial的api变化需要相应修改（直接根据amdgpu的相关commit a78a8da51b3照着抄就行），看来drm子系统的内核api是越来越稳定了 🤣
