Linux Kernel Install Fail Because Broadcom NetXtreme 100G DKMS Driver Build Failed.

richliu — Tue, 27 Sep 2022 08:14:23 +0000

Environment is CentOS 8, broadcom 100G NetXtreme-E series driver .
Host : Ampere Altra Platform

if rebuild the CentOS kernel and there was previous Broadcom nic driver alredy installed, it will trigger dkms to rebuild the driver on current kernel.

make install error as following

[root@localhost linux-4.18.0-80.11.2.el8_0]# make install                                            [55/2101]

 Done.

And check the log file “/var/lib/dkms/bnxt_re/221.0.114.0/build/make.log”

It shows

DKMS make.log for bnxt_en-1.10.2.221.0.114.0 for kernel 4.18.0 (aarch64)
Tue Sep 27 15:41:04 CST 2022
Makefile:603: arch/aarch64/Makefile: No such file or directory
make[2]: *** No rule to make target 'arch/aarch64/Makefile'.  Stop.

Seems cannot find the Makefile, that because the drvier cannot locate right Makefile, because the include architecture is arm64, not aarch64 in Linux kernel .

By the way, basicly arm64 and aarch64 are the same thing, I don’t know why it shows aarch64 on kernel architecture and use arm64 as fold name. probably some traditional history.

solution is easy, go to the include folder and link arm64 to aarch, DONE! ex:

cd /lib/modules/4.18.0/build/arch
ln -sf arm64 aarch64

ubuntu 下安裝 Broadcom wifi driver.

richliu — Mon, 19 Jul 2010 08:19:13 +0000

Linux 下 Broadcom 的 Wifi Driver 可以在 802.11 Linux STA driver 下載到.

不過在 ubuntu 下, 其實這個工作更容易
[BASH]
# sudo apt-get install bcmwl-kernel-source
[/BASH]
然後就會下載並且編好 Broadcom Wifi Driver.
會放在 /lib/modules/[kernelversion]/updates/dkms 下
以我的為例, 就會放在
[BASH]
# cd /lib/modules/2.6.32-23-generic-pae/updates/dkms
# ls -lF
-rw-r–r– 1 root root 10812004 2010-07-01 10:16 nvidia-current.ko
-rw-r–r– 1 root root 2138420 2010-07-16 11:55 wl.ko
[/BASH]

wl.ko 就是 Broadcom wifi 的 module 了, 接下來就是像一般 Wifi 的用法了.

不過這是 STA. 如果是 AP 的話一般人大概是拿不到的.
個人測試過 43225 w/o EEPROM 是沒有問題的.

Intel ICH9 AHCI mode + Windows XP 的問題.

richliu — Wed, 27 Feb 2008 19:11:43 +0000

Intel 官方的 Matrix Driver for Window XP 不支援 ICH9 的 AHCI, 聽說 Vista 的版本是支援的(我不確定, 短期內不想也不會 Update 到 Vista).

如果要在 Windows XP 裝 ICH9 的 AHCI Driver, 就要動一些小手腳, 剛剛 Search 一下, 有找到一篇文章 How to enable AHCI on Intel ICH9 under XP, 利用 Intel 放出來的 Floppy Driver, 改一下 PCI Sub device id. 讓 Windows XP 也可以支援 ICH9 的 AHCI Driver. 大致講一下執行步驟 (不按照原文, 按照原文似乎會有問題)
*注意: 這些步驟有可能傷害你的電腦或是程式, 本人不負擔任何責任..
1. 下載必要的程式
MagicISO (Only needed when you don’t want or can not use a floppy disk.)
32-bit Floppy Configuration Utility for Intel® Matrix Storage Manager
2. 利用 MagicISO 解出 Intel Floppy Matrix Storage Manager 內的 .IMA File.
3. 將 IASTOR.SYS Copy 到 Windows SYSTEM32/DRIVERS 的目錄
4. 編輯 IAAHCI.INF, 將所有字串“2821” 置換成 “2923”
5. 置換字串
PCI\VEN_8086&DEV_2923&CC_0106.DeviceDesc = "Intel(R) 82801HR/HH/HO SATA AHCI Controller"
成為
PCI\VEN_8086&DEV_2923&CC_0106.DeviceDesc = "Intel(R) ICH9 SATA AHCI Controller"
6. 建立 Windows Register
用編輯器建立一個 AHCI_ICH9.REG 內容如下
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\CriticalDeviceDatabase\pci#ven_8086&dev_2923&cc_0106]
“Service”=”iaStor”
“ClassGUID”=”{4D36E96A-E325-11CE-BFC1-08002BE10318}”

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor]
“Type”=dword:00000001
“Start”=dword:00000000
“Group”=”SCSI miniport”
“ErrorControl”=dword:00000001
“ImagePath”=”system32\\drivers\\iaStor.sys”
“tag”=dword:00000019
“DisplayName”=”Intel AHCI Controller”

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor\Parameters]
“queuePriorityEnable”=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor\Enum]
“0”=”PCI\\VEN_8086&DEV_2923&SUBSYS_B0051458&REV_02\\3&13c0b0c5&0&FA”
“Count”=dword:00000001
“NextInstance”=dword:00000001
儲存完畢, 點二下執行

7. 在我的電腦 -> 硬體 -> 裝置管理員 -> IDE ATA/ATAPI 控制器
點 Intel(R) ICH9 2 Port SATA Controller (印像是這樣 :p)
選內容 -> 驅動程式 -> 更新驅動程式 -> 從磁片安裝 , 選到剛剛修改完那個目錄, 將 Driver 硬改成 Intel(R) ICH9 SATA AHCI Controller. 這個 Driver 未經過認證, 就裝下去就對了.

8. 重開機, 調整 BIOS 內的 SATA Mode 從 Compatible 到 AHCI. (各家主機版不一樣, 我是 P5K-VM)

9. 再開機有可能會再要裝一次 Driver, 再指到剛剛改好的 AHCI Driver
接下來會要求重開機, 按照要求重開

10. 檢查裝置管理員 -> IDE ATA/ATAPI 控制器內, 是不是變成 Intel(R) ICH9 SATA AHCI Controller ?

我是有成功, 不過不要問我效能有沒有變快…. 這很難試吧 XD
