必赢亚洲www36netEngadget@COMPUTEX 二零零六:Dell展场拾遗

****在微星Computex
2009的摊儿,摆出了一张长得很像声卡的东西,实际上,它正是声卡,比较特别的是,那张声卡不但主打游戏游戏用户,也主打音响头疼友,一张典故价格落在100到150法郎之间。以下为Annti在会议室打盹梦里见到的,恐怕与真情有出入:1.这张声卡是由二个对声音非常申斥的脑仁疼友PM所基本设计,传闻近年来刚生了一个喜人的丫头2.芯片上用胶布贴起来,就好像不想让任何人知晓是什么样芯片,但一旁焊有内存,传说是创新今后的音响效果芯片3.据他们说微星是买芯片进来,但整个布线是友善统一筹算也自个儿Lay过,假设第二点创制,算是市道上首家跟革新以后买芯片来生产声卡的商家—-At
the MSI booth, we spotted a high-end sound card. This one is not only
geared towards gamers but also Hi-Fi enthusiasts. The price would
probably fall somewhere between 100 to 150 USD. We have some interesting
facts about this card:1. This card is designed by an audiophile who
recently has a very cute daughter.2. It looks like they don’t want
people to know who made the chip because it is taped up. We heard that
it’s from Creative.3. Rumour has it that MSI purchased the chip from
Creative but completely re-designed the board. If the above is true, MSI
is probably the first company to have used Creative chip on their sound
card.

不让ASUS专美于前,MSI 也生产了自已的笔电外接式显卡 Luxium。Luxium
的运维规律和 XG Station 同样,都是经过 ExpressCard 插槽的 PCIe x1
和台式机Computer连接,并将加快后的形象输出到外接的荧屏上。MSI
的外壳一点都不小,大约是一台喷墨打字与印刷机的高低,然而感到起来内部空间相当的大的
Luxium 恐怕在未来会比 XG Station
更易于接受各样品牌的显卡。除了显卡之外,Luxium 还恐怕有多个 USB port 和
一个互联网插孔,何况放置了声卡,除了 7.1 声道输出外,还提供了 SPDIF IN/OUT
和光导纤维输入等,算是那三个多效果与利益的安装。显著地 MSI 瞄准的是和 Asus
同样的商海:出门是精致的台式机计算机,回家插上 Luxium
就成为完整的三十一日游平台。近些日子微星也只策动将 Luxium
搭配自家的一定型号显卡上市,但还不知情会是怎么时候,或售卖价格大致是不怎么。Not
to let Asus have all the fun, MSI introduced their version of an
external notebook video card. It works in pretty much the same manner as
the Dell XG Station — connecting to your notebook via the ExpressCardport and outputing video to an external screen — but in a bigger, more
boxy form that somewhat resembles an inkjet printer. It maybe a bit
large, but MSI representatives say that this allows for better
ventilation, and would allow for easier installation of custom video
cards in the future. In addition to being an external video adapter,
Luxium also has a LAN port, 2 usb ports, and a 7.1 channel sound card
built in, allowing for more versatile use of the system. No price or
date is set, but we do know that it would hit the market as a Luxium-MSI
video card package first, “due to heat dissipation concerns”.

1.1. snd_card是什么

snd_card能够说是成套ALSA音频驱动最顶层的叁个构造,整个声卡的软件逻辑结构起始于该组织,大致具备与声音相关的逻辑设备都以在snd_card的治本之下,声卡驱动的首先个动作一般正是创建一个snd_card结构体。正因为这么,本节中,我们也从
struct cnd_card开始吧。

GeForce 8600GT 展现芯片、补助DD昂CoraII 800 的内存。而且应用笔者的 CPU
调校方式 Turbo Gear,可超频 百分之六十 至
2.93GHz。也由此,在台式机Computer背后扩展个「中号」的散热器,以减弱机体本人温度过高的景况。The
Asus C90 is a DIY upgradeable notebook prototype, with a desktop CPU and
GeForce 8600GT graphics chip installed. Utilizing an in-house technology
called “Turbo Gear”, the CPU can be overclocked 25% to 2.93GHz. That
ginormous heat sink sticking out of the back is a clear testament to how
much power this beast
packs.必赢亚洲www36net 10那可爱的小东西是

2.1.3. 第三步,设置Driver的ID和名字

 

[c-sharp] view
plain copy

 

  1. strcpy(card->driver, “My Chip”);  
  2. strcpy(card->shortname, “My Own Chip 123”);  
  3. sprintf(card->longname, “%s at 0x%lx irq %i”,  
  4.             card->shortname, chip->ioport, chip->irq);  

 

snd_card的driver字段保存着芯片的ID字符串,user空间的alsa-lib会使用到该字符串,所以必须求力保该ID的独一性。shortname字段越来越多地用来打字与印刷消息,longname字段则会出现在/proc/asound/cards中。

Lenovo也做内部存款和储蓄器?应该是挂牌的吧…DRAM from Asus?Hmm…

1. struct snd_card
