Install ATI driver in Slackware 12.0

2008年6月14日 没有评论

Yesterday installed Slackware 12.0 on dell Optiplex 320, and find its default video driver “VESA” only support “1024×768 61Hz”. So download the latest ATI Linux driver “ati_driver-installer-8.443.1-x86.x86_64.zip”, execute unzip and run the codes in text mode, it would display a command line gui for step-by-step configuration and setup. Follow the way, final can see the LCD has already support “1280×1024 75Hz”. It’s very cool and has nice gui of my slackware, even more beautiful than former Mandriva.

Grown-up Life

2008年5月9日 没有评论

Do you know that the harder thing to do and the right thing to do are usually the same thing? Nothing that has meaning is easy. “Easy” doesn’t enter into grown-up life.

I remember once imagining what my life would be like, what I’d be like. I pictured having all these qualities, strong positive qualities that people could pick up on from across the room. But as time passed, few ever became any qualities that I actually had. And all the possibilities I faced and the sorts of people I could be, all of them got reduced every year to fewer and fewer. Until finally they got reduced to one, to who I am. And that’s who I am.

BX schedule of May

2008年5月6日 没有评论

Pang will go to Taiwan tomorrow, just for changing password and re-configure PVG.

According to communication with Poweron TE, I know their requirements clearly and later created a report to Gavin. Poweron needs serial port to control Keyboard, which this port is used for debugging on current BX1200 system. I am going to build the testing environment and find the solution.

WebDisk and PVG would be integrated into a whole system, Pang said this is for convenience to carry the devices to Singapore(Demo Show). It seems Huang Pengcheng has became working on this issue.

Shan, Xiaoyu will arrive at Shenzhen, and he will give a training to Product Departments and Customer Service Team in Shenzhen. He is a good fellow.

FAQ and Feedback form, I will write these two documents in recent days.

Last Sunday, I went to Zhuhai with my wife. Zhuhai is still a quiet city, gray sea, blue sky and hot sunshine. It’s very nice to meet Plasmon’s old friends, Sam, Kevin, and Hans. Hans has been living with his girlfriend, who was working in Guangzhou when I am in Plasmon. Kevin said he plan to leave Plasmon and look for a revive. Sam now lived in 4rd floor, he even brought a game joystick for car racing. Everything looks so familiar, just as happened in yesterday, while it has been about one year. Thank you, my friends. It’s you who make me have the above feeling.

BIOS/CMOS

2008年4月15日 没有评论

BIOS is shorter of Basic Input/Output System, which is stored in ROM/EEPROM/EPROM/Flash. It is a coded program, and uses a dedicated memory called CMOS to keep its implements and setting, for example, date, harddisk driver and so on. It’s a fucking life, while everyone has to live. It’s hard life.

SuperMicro server boards

2008年4月14日 没有评论

Intel 5100: San Clemente

Intel 5400: Harpetown

Intel 5200: Wolfdale-DP

New Super servers and workstations based on the Intel 5100 chipset, with regular DDR2 memory instead of FBD memory, offer superior performance-per-watt and cost-to-performance ratios, because DDR2 memory costs about $10 less per module compared to FBD and generate less heat.

Designed for cost-effective 1U/2U/4U and tower systems, the new X7DCL-i server board supports up to 32GB of DDR2 memory, six expansion slots including three high-performance PCI-Express slots, and six SATA2 ports with RAID5 in a standard ATX form factor. For onboard SAS support, SuperMicro also offer the X7DCL-3, which supports SuperMicro also offer the X7DCL-3, which supports eight SAS ports with RAID5 optional.

Memory manufactories: Apacer, ATP Electronices, Hynix, Micron, Smart Modules, Staktek(Entorian)

Famous researching engine: Naver in Korea, Yandex in Russia

VMDq: Virtual Machine Device Queues is another breakthrough technology from Intel that helps offload network I/O data, processing from the VM monitor software to network silicon.

Receiving Packets: As data packets arrive at the network adapter, a layer 2 classifier/sorter in the network control sorts and determines which VM each packet is destined for based on MAC addresses and VLAN tags, then places the packet in a receive queue assigned to that VM. The hypervisor’s switch merely routes the packets to the respective VM instead of performing the heavy lifting work of sort data, Thus, VMDq, improves platform efficient for handle receives side network I/O and increase CPU utilization for application processing.

EIDE: Enhanced IDE, the latest ATA version is 8, which is also in processing.

48bit address, equals 144 PeraBytes.

1068E chipset and its drivers

2008年4月14日 没有评论

LSI 1068E chipset, by setting a jumper, can be used in 2 modes.

1. 1068MPT-Fusion, PCI ID 1000:0054, Embedded MPT-Fusion BIOS, used with MPT-Fusion(SAS) driver.

2. 1068MegaRAID, PCI ID: 1000:0055, Embedded MegaRAID BIOS, providing RAID 0,1

LSI MegaRAID 84016 SAS controller contains two 1068E controllers and one Intel ICP unit. It driver is megaraid_sas.ko, not mpt_sas.ko as 1068E D.Card in BX1200 platform, which just acts as HBA card.

Act As Filter

2008年3月31日 没有评论

Act as filter, which is used to collect information and analyze it to create valuable report to Gavin. That’s what he told me this morning when I can not reply his step-by-step questions. In fact, I know my situation in the current team. Why did he say above words? I think it is because he wants me to improve myself in a short time. Gavin often is kind man with good manners, and what I should learn from him, is he can control his temperament well and always seemed as calmly. I must response more quickly and be brave in following general working.

BX1600 Project

2008年3月27日 没有评论

On SuperMicro 936a platform with X7DCL-3 motherboard, it can not install Linux on the IDE Disk or CF cards via USB CD-ROM. This has been confirmed by SuperMicro Technical Support, who later suggests me to download the latest BIOS and try again. By the way, in other PC, burn the UIT OS in CF, and it will meet halting as system boot(mkdevices halt), while install UIT OS on SATA disk successfully,the init script in initrd.img and /etc/fstab should be modified with corresponding strings.

When compile new module file(for example, .ko), and put in /lib/modules/2.6.22-16 directory, it is necessary to issue “depmod -a” to update “module.dep” file, which is used by kernel to automatically insert module when system boots. “modinfo” is useful command to check module’s information.

Cache Clean

2008年3月26日 没有评论

I-SCSI Target is not included in the package built yesterday. Rae Chen told me to retrieve iSCSI-Target sources from svn, and then compile it in other virtue machine, which has been configured as compiling environment for BX1200. Note, it should add “make -C /source/linux-2.6.17 -m $PWD”, here /source/linux-2.6.17 is kernel source directory, and “-m” indicates the target directory. And then copied the created .ko to /lib/modules/2.6.17/ directory, and rebuild the installation package. Later I try the package in BX1200, and it still says ISCSI Target module is not loaded. While in command line, issue “depmod -a && modprobe”, it is loaded well. I have to fix this non-automatic loading issue tomorrow.

Inventec decides to return the unit to Taiwan for customer application.

On the new SuperMicro platform 936a(XDCL-3), whenever install Slax and CentOS5.1, both of them can not recognize the IDE-Flash card, while it can be viewed in BIOS setting. It makes the installation process more complicated, I have to install the system in other servers(Tyan 2U), and then replace the card. I should find a solution, or easy way to test.

There will have a meeting about BA880 tomorrow. Something wrong with them in UT. Yang Ke has reported this issue and sent me the relevant log. Perhaps it is related to BS3000e’s bug.

Build HugeMem kernel successfully

2008年3月25日 没有评论

First off, in the linux kernel source, modify .config file to enable huge memory(>64GB). Then build the bzImage, and when issue “make modules_install”, set the target directory to keep the created modules. If do not identify the target path, it will be installed to /lib/modules by default. Second, in my local Mandriva Linux, download the latest BX1200 package, for example, put it into /tmp directory. Unpack the tarball file, and will see three sub directories: /boot, /etc and /opt. Enter the /boot directory, unzip the rootfs.tar.gz.zip, which includes all PHP codes, shell scripts and configuration files in /etc. Replace the kernel file, and /lib/modules/2.6.17. Then create new rootfs.tar.gz, and build new tarball package for huge memory. Later I test this on my local vmware. Note, initrd.img contains all simply boot scripts. It can be viewed by executing “zcat initrd.img | cpio -div”.

BX1600 platform arrives Shenzhen today, which makes a lot of noise. I have to identify the fan speed.
