In may of last year, AMD made announcement of their entrance into the ARM microprocessor line, and the hybridization of ARM and X86.
Long before this, I had wondered if it would be possible for a computer to operate on a hybrid architecture. To task a certain amount of its work to a powerful CISC type processor as well as add a super energy efficient RISC chip to handle co-processing .
This type of heterogeneous computing is being done already with ARM processors using 2 different architectures. However, the two are similar enough that they are assembly code compatible. The ARM big.LITTLE architecture is close to what I am talking about, but still both are ARM v7 processors so not really an ISA hybrid?
I'm talking about an ultra low power, hybrid architecture mobile phone, running an OS like Android, that uses an Intel / AMD x64 processor as its main CPU. With a similarly powerful ARM coprocessor.
A CPU with the performance and compatibility of a desktop PC. More instructions per second at a lower clock, fewer cores equal to the same computing in equivalent ARM chips.
Better software compatibility. No more writing custom kernels for custom chipset. No more blank won't run on blank because of the chipset.
And at the same time, by adding a coprocessor by ARM, an enormous amount of resources can be offloaded to the copro, which means less power consumption, less heat generated etc.
Say your phone had two chips.
One containing a very powerful x86 system with CPU, GPU, SDRAM interface etc. The main " north bridge ".
And a second chip or " south bridge " containing an ARM processor, cellular baseband, DSP , audio, video etc etc.
The south bridge could work independently of the north, allowing for tasks like making calls or processing multimedia to be done on its own CPU; leaving the application tasks strictly to a bad ass 64 bit Intel processor that could run full on i386 Linux or Windows?
Great.maybe the future of Mobile Computing devices

Hey guys,
I've been looking over this document: SD 3.01 Spec specifically from pages 13-15 regarding UHS modes. It would appear that in order for the host to access the card at UHS DDR50 mode, it simply needs to issue another command after initialization. My questions here are:
1) What is the SD host controller on the Nexus One (i.e: is it part of the Snapdragon QSD8250 SoC, or is it a separate chip that it contacts over a serial bus?)
2) Can portions of the AOSP/Kernel/Reverse engineered host controller firmware be rewritten to support UHS-I speeds, or is this impossible in a host chip designed before the SD 3.0 spec was even released?
Thanks in advance.
SD controller is a part of QSD8250.
To access the card, you need to send the command. To receive the card's answer and any communications afterwards, you need HW logic to sample and further process DDR communication. If this logic was present - this thread wouldn't be open...
Aww, was hoping maybe Qualcomm future-proofed the QSD8250 a little bit. Oh well, thanks.
Broadcom announced the release of the raspberry pi's gpu source. Heres what a user on arstechnica had to say about the release; it is most likely whats going to happen in our device and the reason why it will probably never be overclockable unless broadcom alows it to:
Unforunately it's not really open source at all. I'm not too familiar with Broadcom's SoC, but it seems like the bulk of the driver is running on a side processor. The open sourced code simply passes commands and data back and forth between the user's code and the real driver doing the work. Now, a lot of hardware uses firmware these days, so it's tempting to think of what's running on the side processor as firmware, but when the driver running on the main CPU is just an RPC layer and most of the magic (including things like the shader compiler) is happening on the side processor then I would think that any person familiar with the hadware/software interface would rightly say that the "driver" is really the code on the side processor and not the open source code.
Now, having the CPU layer as open source is better than not having it, but this is nowhere near an open source GPU driver. TI does the same sort of thing with their DSP and some auxiliary processors on their OMAP chips, most of the "driver" is running on another processor.
So, everyone
My laptop is annoying me to death because every single time i boot Windows, be it 7 or 8, i can't stay more than 30 mins without getting to Tmax and the laptop turning off. I'm currently developing a game in XNA GS 4.0 so i need Windows for the game to be done...
Question is, can i install Windows XP on my Acer V3-571G laptop with the following specs:
-Intel i5-3210M 2.5Ghz, Turbo Boost @3.1Ghz
-nVidia GT630M 2GB GDDR3 128-bit (Fermi GF108)
-Intel HD4000
-Atheros AR5BWB222 wireless a/g/n (i actually NEED this as Ethernet is already used by an old Linux PC)
-4GB RAM DDR3
-500GB HDD (must set it to Legacy mode for XP setup to boot)
-it's either Realtek HDA or Dolby Home Theater audio
-15.6" HD screen

You can install it on whatever PC that meets the minimum requirements.

Just don't expect to be able to find any drivers. Your GPU will not run, neither will the WiFi, and if you're using a really new system, not even your motherboard.

Hello all!
So I've been using Mac for the last years and really enjoying it, but now wanted to use Linux (more specifically Fedora) as my main OS, rather than MacOS.
The machine for doing so it's a late 2013 15" MacbookPro with NVIDIA graphics.
For getting everything setup it took a while as a lot of drivers are proprietary, but manage to get most things working (expect for sleep, that for an unknown reason is broken and the Mac takes more than 5 min to wake from sleep, and FaceTime camera not working).
The problem however is that the machine is using the NVIDIA GPU, which causes it to get very toasty and drain battery faster.
I would like to enable the iGPU, but keep the NVIDIA GPU available as sometimes I connect an external monitor using the HDMI port.
I am newbie to Linux and have little knowledge but want to try everything possible to make Fedora work as best as possible on my computer. The procedures I tried were:
-Install rEFIND and try to use an set_apple.efi thing but probably did it wrong and did not work,
-Try to modify NVRAM variables to make the mac use the iGPU by default, but when booting to Fedora still only show up the NVIDIA GPU
Any help is welcome, bur please don't say for me to stay on MacOS or that is impossible as I read from people who manage to succored.
Thanks in advance!
