Re: Fedora ARM on Raspberry Pi

<t>Sorry it"s sometime very difficult to be diplomatic in something else than your native language.<br/> <br/> But yes it"s not that hard to make a distribution based on debian that is supported because it"s already the case and you can just make a "distribution" by compiling the Raspberry kernel an...

Re: config.txt

<t>I think you are overestimating the impact of "only" 1,4 V Max. The chip is at 1,2 volts as default which is already pretty close to that.<br/> <br/> It's not with only 1,4 V that you will destroy the device.<br/> <br/> One idea should be to have this never allow overvolting bit.

Re: Will SSD be supported

The crucial advantage of a SSD is not maximum speed, it's latencies. But USB 2 is not known for its good latencies.

The only advantage of SSDs for the raspberry is silence and power consumption.

Re: Will SSD be supported

<t>I don't think you can boot from an SSD. The only way I have in mind to do that is by using a SD card for the kernel (/boot) and then point to the root file system on a USB attached SSD.<br/> <br/> Every kind of storage attached via usb use the USB Mass Storage protocol, which is universal. So is ...

<t>You will save nothing by decreasing the GPU frequency in term of power usage(because it set itself in power saving mode when you don't need it). But you will hurt your performance because the CPU need access to the GPU to have access to the RAM or something like that if I recall correctly.<br/> <...

Re: Swap space on an SD card

<t>One good idea should be to try out zRam.<br/> <br/> zRam compress the ram that should be swapped on the RAM. Even with a slow CPU it's way faster than using a Hard disk to swap. So compared to a SD card this should be a big win.<br/> <br/> But that's not enough for every type of swapping cases. Y...

Re: Github kernel source

Thanks ! I was worried about that. But thinking about it, even if linux can't use the SD slot, I think the root can be accessible on USB. So there is always a way to boot ^^

By the way, is the binary blob already available to download ?

Re: Github kernel source

Is the Raspberry bootable without this module/driver ?

What I mean by bootable is after booting the kernel, being able to read the root file system from the SD card.

Because I am compiling my Linux system right now for my future Raspberry ^^
