FW for Loongson-LS2C5LE

Hi is it possible to get fw compatible with mainline linux for that board?

天创者

刷了新的rom, 南桥风扇不转，天创者的V1.5和V1.4有区别吗？看图片是1.4, 我的板子是1.5,

有无可能支持fwupd

看了看lvfs,上面有arm的板子的固件,框架应该有跨平台的可能
如果能支持的话,希望能尽量引导厂商上传,不然国产机器都不知道去哪找新的固件

无法在新世界固件的 A2101 主板和 L71 笔记本上启动 AOSC OS LiveKit

AOSC OS 的 LiveKit 启动盘在搭载新世界固件的龙梦 A2101 主板和同方 L71 笔记本上启动失败，在 EFI Shell 中发现 bootloongarch64.efi 文件被截断为了 bootloon.efi 的格式。启动盘是用 grub-mkrescue 生成的，但在其他架构上没有发现这个问题（亦有可能是因为其他架构少有超过 8.3 格式的 .EFI 可执行文件名）。

有问题的 iso 可以从这里下载 https://releases.aosc.io/os-loongarch64/livekit/aosc-os_livekit_20230707_loongarch64.iso 。

此外，Qemu 8.0 中并不能复现这个问题。

天创者L5A2主板更新BIOS后启动失败

主板上面的丝印是 LS3A5000_7A2000_EVB_BOARD_V1.5，原来的固件在 UEFI Shell 的 vers 信息如下：

用 spi -u UDK2018_3A5000-7A2000_Desktop_EVB_V4.0.05429-stable202302_dbg.fd 刷入后，重启就没有任何显示输出了。

想请问：

可能是什么样的问题呢..？
固件上有什么调试的办法吗，是否可以确定一下启动不起来的具体原因？（UART..？）

使用edk2固件在qemu启动出错

使用环境为x86_64 archlinux，qemu版本7.2
无论是使用自己编译的edk2固件还是这个仓库里的版本都会报错：

使用这个版本正常启动，但是当使用SATA硬盘时，map中没有fs0设备（虽然能正常检测到AHCI控制器）

A2101 - Can not be upgraded using the upgrade tool in BIOS menu

When I try to upgrade the BIOS from the internal upgrade tool in BIOS v3.25, the following message be shown.
"不支持的固件版本"
BTW, the size of beta8 file is 4128768 bytes. but the size of v3.25 is 4194304 bytes.

The current BIOS file (UDK2018-LoongArch-A2101-pre-beta8.fd) is not signed version.
I have to write the file using the external tool into the flash chip. correct?

天创者NL430i笔记本背光无法调节

天创者NL430i（固件支持新世界），无论是在旧世界内核下还是新世界内核(Linux 6.5.0-4)下，都无法调节背光，/sys/class/backlight 目录直接是空的。我看了一下dmesg里有下面的错误

[ 1.311260] loongson_laptop: acpi_evalf(ECBG, d, ...) failed: AE_NOT_FOUND

我看了一下内核相关的代码(drivers/platform/loongarch/loongson-laptop.c)应该是在调用EC的一个ACPI方法。我dump了一下机器的DSDT表发现HKEY设备直接就没有ECBG这个方法。与之相反，航天706所的龙芯笔记本的背光是可以调节的（当然它只支持旧世界），它的DSDT里的HKEY设备里面ECBG方法就是有的。所以这个背光无法调节的问题应该是出厂固件的bug。请问能否提供修复bug之后的固件？

附NL430i和706笔记本的DSDT和dmesg dump Link

A2101 - Crash running "ls" in grub shell after removing a USB stick

When I booting the system with a USB stick plugged in, the boot failed because (hd0) changed from the HDD to the USB stick. It's not an issue: such behavior is very common among all motherboards. But when I removed the USB stick and tried to verify with "ls" in grub shell:

天创者主板开关机时会有长滴短滴的响声

天创者主板开关机时会有长滴短滴的响声；
需求：
1、能否提供下各报警声音的具体含义？（比如长滴一声，短滴一声的代表什么？）
2、能否对RELEASE版本关闭滴滴，或者只短滴一声？
谢谢

7a2000 evb iommu初始化失败

最新的固件配合chenhuacai/linux@7316858 仍然有can't derive routing for PCI INT A的报错
chenhuacai/linux#2
内核维护者认为prestable202308固件没有传递正确的中断信息。因此重开一个issue。

Feature request: Expose the LS7A watchdog via an ACPI WDAT table

This is handy for kernel development and certain use cases wanting some reliability. It's very convenient and preferable to have the device exposed via WDAT so we could avoid registering a platform device in Linux for that. (Currently there's no platform device usage in arch/loongarch so we'd really like to protect that "purity".)

See also https://lwn.net/Articles/701235/ for some background from the Linux side.

3A5000-7A2000-EVB (and maybe others): Add an option for automatically starting the system when the AC power is connected?

I want to access my 3A5000-7A2000-EVB via SSH when I'm out for vacation. But occasionally a 5-minute power rage happens in my apartment, then the system is down and I cannot restart it until I return.

Can we add an option to automatically boot once the AC power is (re)connected? I remember there was such an option in A2101 old-world firmware.

Or maybe this option already exists but I didn't find it?

Wonder about my motherboard type

My motherboard looks like ML5A, but board information shown in the system looks more like L5BMB01-CRB. I don't know which firmware suits my board.

请求增加ML5A_MB(L5A1)固件

L5A1是天创者主板，京东上还有在售卖，本仓库提供的固件目前没有针对集显的显存进行初始化，我们需要做集显驱动，请求帮助 @lichao

天创者 L5A2 每次主机关机（电源未断），再开USB设备都不工作，如键盘，鼠标。需要重拔插一下

开机时，键盘三个灯都会亮一下。但马上就灭了。
已经更新为202308的bios，之前的202303也有这个问题。

天创者L5A2主板更新BIOS不成功

天创者L5A2主板更新主板厂家给的版本：LS3A50007A-6-1-pason.fd后显示的版本号是：Loongs0n-UDK2018-U4.0.05420-stable202302
然后下载本仓库UDK2018_3A5000-7A2000_Desktop_EVB_V4.0.05429-stable202302_rel版本固件升级后不成功，bios版本仍然是显示厂家的版本，spi -u命令是显示两行ok的

用这个固件在qemu上启动自己的内核，进入了uefi shell，如何进一步引导呢

我编了一个nuttx内核，龙芯架构。
qemu命令：

./qemu-system-loongarch64 -m 4G -smp 1 --cpu la464 --machine virt -bios ./bios/edk2-loongarch64-code.fd -kernel ./nuttx -vga none -nographic -gdb tcp::1122 -S

看起来只能进入uefi shell，这个内核没有文件系统，直接用-kernel指定了内核。
启动以后，进入了uefi shell，请问接下来如何引导内核？

Reproducible with both the grub in LoongArch Arch Linux 2022.06.16.1 ISO and my Gentoo grub package.

@yetist says the LoongArch Arch Linux's grub should be working, so I guess this might be a firmware problem. Strange indeed...

LM-LS3B5000-7A1000-2w-V01-server_A2114 - Firmware needed

Does anyone have the new firmware for this board?
It is named as LM-LS3B5000-7A1000-2w-V01-server_A2114.
On both CPUs there is a "Primitive sample" sign.
Athough the CPU shows LS3A5000 on the package, it is actually recognized as loongson-3B5000 in the BIOS, and it has a frequency of 1.6Ghz.

3A6000 (XA61200 V1.10): Resizable BAR switch causes Breakpoint Exception if an external GPU is connected

When I enable both "Above 4G decoding" and "Resizable BAR switch" with a GPU (AMD RX550 640SP) connected on the XA61200 V1.10 board, the firmware triggers a Breakpoint Exception:

I can work it around by removing the external GPU, turning off "Resizable BAR switch" (via the serial console, thanks to it I don't need to reprogram the flash!), and then reconnecting the GPU. Interestingly, the kernel still reports BAR size = 4GB even if "Resizable BAR switch" is off and "Above 4G decoding" is on.

刷写内存条spd JEDEC参数以后性能没有对应提升

我的主板是 A2101 固件 vUDK2018-LoongArch-V4.0.05132-beta10
内存是镁光 CT8G4DFS632A.M4FB 8GB ddr4 3200 x2

默认参数为 3200 CL22/24/26
我用内存条spd编程器修改内存jedec参数为 3200 CL20， STREAM性能提升非常小：

请问固件的内存训练，是否遵循JEDEC标准的各种参数进行训练
如果为否，固件是否可以提供内存参数调节界面

UDK2018_3A5000-7A2000 固件是否能提供rel版本

202308的固件是否能提供rel版本
（dbg版本启动会多耗调试信息输出时间，但我没有串口，所以就算有输出什么有用的信息我，也看不到）

后续会有更新版本的固件吗？比如新的stable固件，以及中文支持

a2101: one PCIE slot does not work

The PCIE x4 slot most close to CPU does not work. Another PCIE x4 slot and the PCIE x16 slot work fine.

I've checked to BIOS setting, all PCIE ports are "enabled".

To make things worse, a double-slot GPU plugged in the PCIE x16 slot would physically block the only working PCIE x4 slot so I have no PCIE x4 slot to use now :(.

Booting new world open source Linux ditro on 3A5000-7A2000-EVB

Hello chinese friends!

I have motherboard 3A5000-7A2000-EVB v1.5 with UEFI (BIOS) firmware Loongson-UDK2018-V2.0.05269-beta8 which seems to be much older than DK2018_3A5000-7A2000_Desktop_EVB_V4.0.05383-beta10_dbg.fd in this repository.
https://linux-hardware.org/?probe=2fea9476f5

I have successfully booted and installed Loongnix 20. It is an "old world" Linux distribution built with non-upstream toolchain. This article https://blog.xen0n.name/en/posts/tinkering/loongarch-faq and https://lpc.events/event/16/contributions/1178/attachments/1000/1948/lpc2022-loongarch-20220913.pdf say about new and old worlds. Now I want to boot an open source new world Linux distro built with upstream toolchain (gcc, binutils). But I cannot boot any of them.

First, I tried to boot LiveCDs , e.g. https://github.com/fedora-remix-loongarch/releases-info , in virt-manager (qemu) which is preinstalled in Loongnix and got "cannot allocate memory for memory map"

I tried to add initrd+vmlinuz from them into Loognix's Grub bootloader. It froze when trying to load them.

Then I tried to replace /boot/efi/EFI/*/grub*.efi with Grub EFI binary from a new world LiveCD and got the same error, now on the real machine:

The only thing that comes to mind is that this UEFI (BIOS) version does not support new ISA/ABI (how to name it correctly?).
There is no "Security" page in the UEFI, so updating via a EFI shell will probably be the only option. But I am afraid to brick the motherboard.

Could you please comment if updating firmware is the right solution to run new world LoongArch binaries?
Thanks)

请求增加航天706所的天熠TR41A1笔记本新固件支持

这款笔记本电脑用了一年有余，扩展性不错，支持2个固态硬盘，内存可扩容到32G，7A1000桥片显卡，机内机外接口齐全，很适合用来跟踪了解龙芯上有社区代码提交动态，也有一定的用户基础。曾就新固件联系过厂家技术，目前没有新固件支持，所以很是希望龙芯能提供这款笔记本的新固件，热盼回复！

希望串口控制能更完善一些

现在的串口可以代替键盘做输入，但是完全是盲敲，回应在串口上没有，只显示在屏幕上，
如果ansi的屏幕控制比较麻烦，或者只让uefi的shell 能够在串口工作，也很好，对于远程维护和远程安装系统，帮助很大。

3a5000 7a2000 evb 请求支持HMA82GR7CJR8N-XN RDIMM

目前固件在write leveling时发生错误。

查看memconfig，发现RDIMM应该是被支持的，至少没有直接报错。

如果有需要，我可以把SPD参数读出来。

天创者主板固件是否能增加中文语言支持

毕竟龙芯品牌，没中文说不过去XD
