瞎灌一贴，以寄托我对flytomoon的哀思 :(

少了你,水坛又该寂寞了! :(

完了，估计这贴要被yaya淹没了 :P

 :D

难得见你放分，
我一定要灌。
 

不能让yaya一个人把分都拿走。

我们一起来灌好了，
看谁灌得多。

 :D :D

你难道就不能定为6k吗？这么没追求？？ :D [/quote]应该定10K [/quote]

灌

灌？灌！

水啊

水不嫌多，分不嫌少

坚持不懈

排除万难

将分灌倒

下分吧老天

Prior to co-founding Azul Systems, Scott founded 3dfx Interactive, a graphics processor company. Scott served at 3dfx as Vice President of Engineering, CTO and as a member of the board of directors and delivered 7 award-winning products and developed 14 different chips. After a successful initial public offering, 3dfx was later acquired by NVIDIA Corporation.

Sohu的独家报道指出中科院的龙芯2号已经研制成功，龙芯2设计频率为500MHz+，性能相当于1GHz+的P3或者P4，但是目前龙芯2只能达到300MHz:

\"近日，搜狐IT从龙芯I号设计师处了解到，由中科院计算所承担设计开发的CPU（中央处理器）龙芯2号已经研发成功，其实物将于12月20日在中科院计算所的成果汇报日期间首次公开亮相。

据参与项目开发的技术人员介绍，目前的龙芯2号最高频率为300MHz，功耗1W-2W，成品率约为80%左右。通过使用相关测试对龙芯2号的性能分析表明，相同主频下龙芯2号的性能已经明显超过PII，达到PIII的水平,设计人员称龙芯2号的设计SPEC CPU2000分值可达到300分以上,设计频率在500MHz以上.性能可与1GHz以上的PIII或PIV的性能相当。\"

联想集团公司的新标在4月28日10：30正式发布，这可是中国IT界的一件大事。新标志为“LENOVO”，读音为NO发重音。

The Global Cancel Spin Lock
The original Microsoft scheme for synchronizing IRP cancellation revolved around a global cancel spin lock. Routines named IoAcquireCancelSpinLock and IoReleaseCancelSpinLock acquire and release this lock. The Microsoft queuing routines IoStartPacket and IoStartNextPacket acquire and release the lock to guard their access to the cancel fields in an IRP and to the CurrentIrp field of the device object. IoCancelIrp acquires the lock before calling your cancel routine but doesn’t release the lock. Your cancel routine runs briefly under the protection of the lock and must call IoReleaseCancelSpinLock before returning.
In this scheme, your own StartIo routine must also acquire and release the cancel spin lock to safely test the Cancel flag in the IRP and to reset the CancelRoutine pointer to NULL.

Hardly anyone was able to craft queuing and cancel logic that approached being bulletproof using this original scheme. Even the best algorithms actually have a residual flaw arising from a coincidence in IRP pointer values. In addition, the fact that every driver in the system needed to use a single spin lock two or three times in the normal execution path created a measurable performance problem. Consequently, Microsoft now recommends that drivers either use the cancel-safe queue routines or else copy someone else’s proven queue logic. Neither Microsoft nor I would recommend that you try to design your own queue logic with cancellation because getting it right is very hard.

The Microsoft class driver for HID devices, HIDCLASS.SYS, provides the overall framework for WDM drivers that manage HID devices on all the Windows platforms. Microsoft also supplies a HIDCLASS minidriver named HIDUSB.SYS to handle USB devices whose device or interface descriptor indicates that they belong to the HID class. Consequently, if your USB device belongs to the HID class, you may not have to write a special-purpose driver at all because the Microsoft class driver and minidriver fully support the USB specifications.
