Linux To Be First OS To Support USB 3.0
An anonymous reader writes with an excerpt from Neowin.net "Sarah Sharp, a self-styled 'geekess' and Linux developer at Intel's Open Source Technology Center who has recently been working on the Linux USB subsystem, announced on her blog that support of USB 3.0 will soon be integrated into the Linux kernel. This makes Linux the first operating system to support the standard. If you can't wait and have the expertise necessary, she includes instructions on how to get USB 3.0 support in Linux now." Here's Sharp's post.
That's simply not true. The USB 3.0 spec. is mostly concerned with the phy. & bus. The xHCI spec covers the HCD. The software-level device interfaces have not changed, or have changed very little.
Syllable : It's an Operating System
Neither Amiga (Virtual desktops in 1985) or NeWS (tabbed windows and browsing, 1988) were open source.
Do you even lift?
These aren't the 'roids you're looking for.
Err, Mrs LizardKing once said that she'd attempted sex when she had the painters in, and that it was uncomfortable because the menstrual blood caused chafing. Apparently a ladies "red wee" is a bit like unstrained orange juice - it's got bits in it.
And no, I can hardly believe we're discussing menstruation on Slashdot. In response to an article about a serial interface.
So does that mean CPU usage will be 100% when I copy files to a hard drive?
USB 3.0 does away with polling (which is what causes the high CPU usage) with an asynchronous event model whereby the device controller sends service requests to the host (unfortunately, I can't find a great reference for this, although they mention it here).
Or, to put it another way, it allows USB to enter the 20th century. :)
