Hello, I need some help with pciconf.
There's a video chip, called Intel GMA945 (sometimes, GMA950), it's being included inside of a lot of netbooks and even notebooks/desktop PCs. On netbooks, the bus is underclocked to 200 MHz, to save the power and to lower the heat being produced by it. There was a tool called gmabooster, both for Windows and Linux. What it does is that it simply sets the FSB of that chip back to 250\400 MHz and here you go -- you get a faster performance, no more underclocking.
There's a shareware tool from one greedy programmer available for Windows, while for Linux it was possible to do with this simple sh script:
02.0 is the address of our VGA adapter in Linux, found by lspci:
Now, here's the deal: there's no setpci tool available for FreeBSD. The closest one I found was pciconf, but there's absolutely no information on the web about how to work with it.
Here's a part we need, from the output of pciconf -lvbc:
It's pretty similar to Linux's one, as we can see.
What I cannot figure out is how to set the values. At first, I thought that cap 01 was the parameter I needed (d0 = null, d1 = 200, d2=250 and d3 = 400 MHz), but that powerspec D0 D3 is available almost for all PCI devices.
That's why I need some tough help here, considering how to set that f0.b=00,60 and f0.b=33,05 with pciconf.
Thank you!
