    Phoronix: Freedreno's MSM Updates For Linux 4.11, Code Aurora Prepping More Contributions

    Freedreno founder Rob Clark has sent in the MSM DRM driver changes to DRM-Next for Linux 4.11. Separately, Qualcomm's Code Aurora is prepping more contributions for this open-source Qualcomm Adreno driver for Linux...

    Umm... Michael, is this a typo, or is it intended?

      Can Qualcomm open stuff needed for using Nexus 5 with upstream kernel?

        All the freedreno news got me browsing around and end up on a Inforce 6640 product page (that subsequently went 404). It had a Snapdragon 820 with all the usual SBC ports, a bunch of MIPI connections, and a Atheros 8151 PCI Express GigE, and a price of $240. Should've printed it out as a PDF for maximum leak.

        I do hope they bring it out, much more reasonable price than the other SBCs with a 820.

          That's intended, it's referencing the AMDGPU DRM driver's kernel scheduler.

            IFC seemed an ok option for a while, mainly due to price. Problem though, is I've had some serious problems with some of their hardware (for instance, certain revisions of the IFC 6410 had some voltage regulators that were inadequate, overheated, and caused crashing). I never was able to get the desired stability of of their hardware. They are also seriously cagey with the code and force you into NDA's, which frankly, isn't acceptable.

            This, however, looks VERY much more interesting;

            (note that the page was last edited yesterday, so this isn't one of those dreams that has fallen apart... at least not yet.)

            Also note that its an EXTENDED board, with a PCIe slot!
            Also, 3 camera inputs, two USB3-A sockets...

              robclark as Qualcomm is pushing code to freedreno, doesn't it qualify as official Adreno driver? Or it will be official only when they endorse it?

                Rather unfortunate that the Inforce boards are flaky.

                I've seen the Dragonboard 820c also, and assuming it falls into the below $300 when it's available, it might be tempting.

                My biggest issue with it is arrow, I'm rather annoyed at them. A few years back I noticed on their online catalog a "discounted" AMCC 460SX Dev board for the princely sum of 0.24 US cents plus shipping. So I put an order on one and they do ship it, but they charged an extra 50$+ (for shipping) above the already paid price without asking. Can't really remember how much it was exactly. Pretty much stuck to using Mouser, Digikey and RSDelivers after that.

                The board itself is quite interesting, it's a PowerPC 460 (unfortunately without an FPU) - full ATX board with 3x PCI-e 4x slots and ddr memory slots. It also came with a ATX power supply - which is probably why the express shipping was a tad expensive.

                And don't get me wrong, it was still really cheap for a full atx dev board.

                  not sure what counts as "official" but qcom has been using the upstream driver for a while (not on any android devices, I don't think, but industrial/catalogue market where clients want upstream linux support)

                    I also have an Ifc6410, mainly bought because it was the only ARM SBC with an open driver at its time. Waste of money ...

                    The code release policy is really embarrasing. By itself, the board is well capable of either booting from the onboard NAND or an SD card. The second option would allow to create disk images to be copied to an SD card, but due to their redistribution policy of the bootloader blobs (or lack thereof), this is not possible.

                    Now this may be due to Qualcomms release policy, which seems to be a little bit better with the 96boards listed Snapdragon 410e based boards, but still I could not find any redistributable bootloaders for these boards. I don't require any source code (still dreaming), but a clear redistribution license.

                    Seems strange, but any Allwinner or Rockchip based board is much nicer in this respect. You don't need any complicated vendor-only bootloader chain, but can stick u-boot on the SD/eMMC/SPI ROM and are done with it.
