Raspberry Pi SoC drivers now fully open source

Mage
Silver badge

Re: err -Weeps

Well, I read the article and hadn't looked at the release.

So I'll stick with the recommended Linux distro for now. Raspbian “wheezy”

http://www.raspberrypi.org/downloads

So the release here http://www.raspberrypi.org/archives/2221

is misleading?

"As of right now, all of the VideoCore driver code which runs on the ARM is available under a FOSS license (3-Clause BSD to be precise). The source is available from our new userland repository on GitHub. If you’re not familiar with the status of open source drivers on ARM SoCs this announcement may not seem like such a big deal, but it does actually mean that the BCM2835 used in the Raspberry Pi is the first ARM-based multimedia SoC with fully-functional, vendor-provided (as opposed to partial, reverse engineered) fully open-source drivers, and that Broadcom is the first vendor to open their mobile GPU drivers up in this way. We at the Raspberry Pi Foundation hope to see others follow."

OTH if it's possible now to load and use the GPU binary and call it from your own hand crafted OS off the SD card it's some good.

Now we can experiment with new designs of OS, rather than playing on top of 20 year old RiscOS and Linux.

Windows 8: An awful lot of change for a single release

Mage
Silver badge

Windows NT 4.0

Negative:

GDI moved into Kernel: Graphics and Printer drivers able to crash OS for first time.

The next iteration of PCs added more performance than that change. It was a mistake. There was even a perfectly good Explorer shell (preview) just before NT 4.0 that ran on NT3.51

Positive

NT 4 enterprise could access 16G of RAM, breaking 2G limit

NT 4 enterprise supported cluster on standard HW if you had a 2 channel SCSI, SCSI repeaters on both PCs and two external SCSI shelves mirrored across the channels.

NT4 as well as x86 supported Pentium Pro (rubbish running 95), MIPS, Power PC, Alpha and 64 bit Alpha.

CE was based on NT. Only the GUI of CE was stupid for small device. Zune fixed that.

The demise and then dismemberment of DEC by Compaq, then disastrous HP take over (ditching some of the best of both companies) was bad.

DEC ARM designs live on in Marvell though after Intel took them and resold them.

Re: Win CE

From a marketing perspective. Yes, CE has run on ARM for years and it has more in common with Windows NT (2000, XP, Vista, 7, 8) family than Win on Dos (3.x, 9x, ME) family.

But CE resource / process limits are static, hard coded for tiny RAM and ROM. Win NT (Win 8) is dynamic allocation more suited to the ARM in Smart phones that has more physical resource than a 2001 x86 Laptop!

Re: assumption that I am missing something importan

Yes, the Pi uses a custom boot that has the binary blob for GPU and other chip specific features.

It's not simple at all to change to a different Linux distro without losing functionality, or indeed to have a completely diifferent OS (though work is happening on porting RiscOS as was on Archimedes, but it's a desktop OS too) .

The Broadcom chip specs are not public. The ARM Chip on the Ardunio is public, you can easily write your own bare metal software or simple OS with Timer tick and "round robin" scheduler.

There is a much similarity between some ARMs as 286, Pentium Pro, Xeon and Itanium have. Good luck on getting ANY OS on Arduino ARM to run on Raspberry Pi! Even with recompiling.

The chip on the Arduino ARM is designed specifically for Industrial / Embedded control. Likely has general purpose timers and and general purpose Analogue I/O.

The Raspberry Pi is a mobile phone chip on a breakout board. So not very suitable for embedded applications. There doesn't seem to even be analogue in (USB stick for Audio in certainly).

Linux

Real time on Pi

No, it's the OS.

Ordinary Linux or Windows or iOS or OSX can't even reliably do 2.4kHz sampling to read 1124 bps RDS data, or 38KHz OOK modulation without jumping through hoops in a Device Driver, directly in software with a GPIO pin. An 8bit Arduino or PIC can do it easily.

The official support for Pi is a customised Debian flavour of Linux. You need a keyboard, 4G SD card, HDMI screen (composite is too awkwardly low resolution) and USB2go plugged 5V PSU (the USB2go connector is just power, no data). It can't be bricked as the OS boots from SD card.

So to use the GPIO on Raspberry Pi you need to figure how to either boot a "Real Time" version of Linux (which isn't very real time), or better is some other non-Linux OS.

The Multitasking model in Linux can't assure that a user task is run when you want it, no matter how fast the CPU unless a new kernel patched in Device Driver is added.

Nokia puts Symbian out to pasture ... why not release it into the wild?

Mage

Happy

Re: Symbian pre-re-closing from 2010 is still around

If it's going to be recycled as a lean RTOS (with optionally a sensible new GUI for things that need one) you don't need to be able to "build" anything "Belle" compatible. In fact you want to avoid like plague ANYTHING using existing Nokia GUIs over last 10 years. You only want the OS

As to what should be a layer for graphical / User I/O applications I don't know. I've tried building QT based applications for Window / Linux and found Java cross platform GUI libraries better. Not that I think that's a good idea. despite that Android is essentially Linux + a flavour of Java (Davik vs JVM)

Re: Move on and let it die

iOS and Android are what they are, bloated macro kernel OS based on UNIX/Linux concepts. iOS & Android developers are not going to scrape the core of the OS and re-write it from scratch. That though is the only way to get an efficient, secure, low power, reliable and low footprint OS.

Symbian was developed from a OS especially designed from ground up for a single user running multiple small applications in tiny memory on battery powered cpu.

UNIX was designed for mains powered Mini-computers and multiple users. Linux was designed as a functional clone for the 386 CPU with disk storage. It's only because a mobile phone is more powerful and more storage than a 2001 Laptop that iOS or Android is practical at all.

Symbian OS developers are going to want to work on ARM embedded systems, not iOS and Android phones.

Symbian *was* open source for a while. How they get the genie back in the bottle? An embedded controller or other application using a Raspberry Pi needs none of GUI junk that Nokia built on top of Symbian. If you DON'T have screen on the Pi, then VXworks, QNX, or Symbian may make more sense than Llinux which needs a hacked kernel to be "real time". Set-boxes, TVs, WiFi points and Routers can cheerfully use vanilla Linux as there are no "Real Time" constraints or "deterministic at compile time" requirements.

TiVo: Cisco and pals could owe us BILLIONS over DVR patents

Mage
Silver badge

Re: someone must have invented the DVR?

Digital video goes back to early 1970s or late 1960s.

The reason it wasn't in the home was cost of disc storage and cost of video DAC/ADC. Decent codecs help dramatically reduce the storage cost. But TIVO can't claim ANY patents on video codecs or video storage on HDD.

By mid 1980s some PABX used audio codecs and HDD for voice mail. I worked on HW & SW of these and they incorporated most DVR functions apart from EPG scheduling, audio only rather than video.

VHS machines eventually had "EPG" scheduling via Teletext data.

Re: Cloud?

I understand perfectly that TBP doesn't store the copies themselves and is using encryption and routers etc.

But at the end of the day they are the wrong peolple to cheer, they are not doing a single iota of good nor advancing any cause. They are egotistical parasitical scum that get far too much publicity. Their "information" to enable people to download do live on real servers somewhere. The "Cloud" is purely a marketing concept, Routing, load sharing, virtual machines etc practically pre-date the internet and certainly pre-date websites.

I'm baffled as to why the smart people here would cheer on these idiots.

Cloud?

Just marketing for Hosted Services on real servers somewhere. It's no different at all to having servers of their own at a number of different data centres.

Whether or not their site(s) run on a virtual server or not isn't relevant either.

Virtual Servers and so called Clouds use real servers in real buildings in real countries.

I'm 100% opposed to pursuing downloaders or blocking people's internet to ANY server (doomed to failure) or cutting of people from the Internet.

But these people are no latter day Robin Hoods. They are at best parasites and at worst criminals. Just because the Media Industry is nuts and charges too much and doesn't recompense the artists and production crew enough doesn't give them the right to distribute.

I admire people that create, I admire people that pay to support that. I despise parasites and criminals dressing up their actions as somehow beneficial.

I refuse to believe a tablet-centric Windows designed by Marketing Dept that played with a Zune is creating an "Osborne effect*", or "iPhone" anticipation on Windows 7 sales.

Combination of Corporates waiting for Windows 9 or 10 or better "linux" and ordinary consumers "taking the Tablets", because really most don't need a real PC.

Re: The ARM chips might make that a little tricky

No,

I've been running Linux on ARM since 2005. It's been available much longer.

Where do you think the Pi eaters got Linux? It's available for ARM. Actually isn't Chrome OS really just Linux + a browser and everything else locked? Like Android is essentially a Linux variant + Davik (Google's flavour of JVM for Google's flavour of Java) + Browser.

My LG TV isn't intel either and runs a version of Linux.

About 1000 ARM cores ship per x86 Core I think and a lot of them run some sort of Linux. Some run VXworks or QNX or Windows CE (apart from ARM based phones running iOS, Android/Linux, Brew, QNX, Windows Phone (based on CE till v8), Symbian, Badu etc).

There is a big big world out there beyond the x86 and Windows. Don't be surprised if Mac Book or Mac Air drops x86 for ARM as soon as it makes more profit and little difference to User. They want OS X to be more like iOS anyway)

Re: Is it just us?

Also the Modem or phone "jams" cable broadband or Cable TV in the same room. No filter or solution other than moving the phone / modem about 10m away from anywhere the cable, connections, setbox or modem is.

I surprised Virgin hasn't been complaining more.

Really the whole "Digital Dividend" idea is stupid, The frequencies 900MHz to 2600MHz allocated for Mobile are poorly used and more than enough for Mobile.

Really future DTT services need the spectrum and the 800MHz band results in cells too large for good Cellular data capacity. The Digital dividend was based on idea of Digital only replacing Analogue, no HD, no 3D no Ultra HD, no extra channels no pay Channels.

Re: Think of the Children!

You can get audio at the difference frequency between Video and Audio carriers, and harmonics, so 6MHz, 12MHz, 18MHz etc for 625 TV. About 4.x something MHz on 405, long time ago, I don't remember.

The Audio IF strip if on carrier rather than "intercarrier" is 6MHz below video IF usually, so about 33MHz approx for 625 line.

USA used 44MHz Video IF and Europe usually 39MHz approx for 625 line. Earlier 405 sets used various frequencies from about 12MHz to 44MHz. Earliest 405 sets simply tuned one 42MHz approx channel directly with NO IF, later in 1955 the first set boxes sold for Band I only sets to get ITV on Band III

Could it be that NAND Fab plant building isn't happening because perhaps it's still a premium price niche market as well as the uncertainty over alternate technologies. I think there may be more than the three mentioned in the article.

Marconi's assistant told Marconi about the glowing crystal, but like many successful entrepreneurs, he had a single obsession, to make money from Radio. As it wasn't a good radio detector, he wasn't interested.

I knew Losev had published about LED. I didn't realise he had an LED patent though. He also described a "Transistor" (not called that then) but unfortunately most of what he wrote on that was destroyed in the War.
