intel xe驱动

shangyatsen

使用这个分支的drm/xe能驱动intel dg1，实测能点亮进桌面。存在三个问题: 1. dma_fence有个warn，dmesg会打印日志。2. 鼠标指针运动时，会跟着一个花屏小方框。3. 声卡没驱动，msi有问题。

新世界新驱动，给楼主探索的热情点赞

淡炒番茄

不是说intel独立显卡只能用在intel主板上嘛？而且还是要新一些的主板，据说是vbios在bios里面？

xry111

淡炒番茄没 VBIOS 的话只是内核引导前要盲开。目前 AMD 比较新的卡在 3A6000 上也是关掉 VBIOS 盲开的，因为 BIOS 里面模拟执行 VBIOS (都是 x86 指令) 的模拟器有问题，在 3A6000 上模拟比较新的 A 卡会炸掉。

Anyway 据 phoronix 的报道 Xe 驱动目前哪怕在 x86 上都一堆 bug，而且 Linus 也抱怨它“严重缺乏测试”。

太6了😂话说能不能开qsv？

shangyatsen

https://github.com/FanFansfan/loongson-linux/tree/loongarch-xe 新的6.7分支的驱动，当前把kunit都跑过了，igt-gpu-tools还有大量测试case有问题，用户态的pthread_barrier似乎也有问题。

桌面环境能运行起来了，但仍有不稳定问题

glory

主板型号：ML5A_MB 无显存无集显输出版本

CPU型号：龙芯3A5000LL

桥片型号：龙芯7A1000

编译6.8.1版本内核，以打开xe独显相关选项，但开机后lspci依然找不到dg1显卡，dg1也没有显示输出，但风扇正常转，请问是什么情况？

shangyatsen

glory dmesg看pcie有没有错误

shangyatsen

glory 额，看上去固件枚举设备可能有问题。要么看下固件日志，提交issue，要么尝试内核选项,pci nocrs, realloc重新枚举设备。

glory

shangyatsen 试了pci=nocrs,realloc 还试了pci=noacpi,nocrs,realloc又或者pci=nocrs,realloc noacpi,都不行，还是这样不识别

shangyatsen

glory 那无了，串口下固件日志github提交一下issue
