Just a couple of weeks ago, we reported on the status of Raspberry Pi 4 Vulkan driver & future plans based on a presentation made by Igalia at the Open Source Summit 2020 at the end of October. At the time, the V3DV Vulkan Mesa driver for Raspberry Pi 4 was merged into Mesa, passed over 100,000 tests in the Kronos Conformance Test Suite (CTS), and was said to implement the full Vulkan 1.0 API. So it should come as no surprise that Khronos has now declared the Raspberry Pi drivers to be conformant with Vulkan 1.0 specifications. This was tested in Raspberry Pi OS with Linux 5.4.51 using X11 display server at 1920×1080 resolution on Raspberry Pi 4. Vulkan 1.0 conformance means the V3DV Mesa driver has passed all tests from Khronos CTS and should be compatible with most applications using this version of the API. The drivers will work on all Broadcom BCM2711 platforms including Raspberry Pi Computer […]
Last week, we wrote about Raspberry Pi 4 Vulkan project status and future plans, and one person commented they are currently trying to get dxvk to work Box86, and that CNX Software should write about the latter. Cool, but what does that mean? dxvk is an open-source Vulkan-based implementation of D3D9, D3D10, and D3D11 for Linux, and Box86 is a Linux userspace x86 emulator that works on 32-bit Arm targets like the Raspberry Pi SBC. Nice, and I remember I ran x86 Linux and Windows on Raspberry Pi a few years ago using a closed-source commercial program called Exagear, but having an open-source solution is even better. That means 64-bit Arm is not supported at all, and Box86 can not even be built for Aarch64 targets. Since many x86 games require OpenGL, as opposed to OpenGL ES, Box86 works best in conjunction with gl4es. By installing Box86 on Raspberry Pi 4, or other Arm boards like many of the Rockchip […]
Last year, Imagination Technologies unveiled IMG A-Series GPU family scaling from low-power IoT to mobile and high-performance server applications with up to 2.5 times the performance of the earlier PowerVR 9-series GPUs, as well as eight times faster AI processing and 60% less power under similar conditions. While I’m not aware of any SoCs announced with the new IMG A-Series GPU yet, the company has already announced the next-gen IMG B-Series GPU family with up to 4 times the multi-core performance thanks to decentralized multi-core technology, 30% lower power consumption, and 2.5 times the fill rate. The company offers four types of IM B-series GPU, each optimized for specific applications IMG BXE for high-resolution displays – From 1 up to 16 pixels per clock (PPC) BXE scales from 720p to 8K for UI rendering and entry-level gaming. IMG BXM designed for mid-range mobile gaming and complex UI solutions for DTV and other markets. IMG BXT four-core high-performance GPU generating 6.0 […]
Linus Torvalds has just announced the release of Linux 5.9 on lkml: Ok, so I’ll be honest – I had hoped for quite a bit fewer changes this last week, but at the same time there doesn’t really seem to be anything particularly scary in here. It’s just more commits and more lines changed than I would have wished for. The bulk of this is the networking fixes that I already mentioned as being pending in the rc8 release notes last weekend. In fact, about half the patch (and probably more of the number of commits) is from the networking stuff (both drivers and elsewhere). Outside of that, the most visible thing is a reinstatement of the fbdev amba-clcd driver – that’s a noticeable patch, but it’s basically just mainly a revert. The rest is really really tiny (mostly some other minor driver updates, but some filesystem and architecture fixes too). There’s just a bit more of those kinds of […]
AOMedia AV1 royalty-free video codec delivers up to 50% better compression than H.264 and up to 20% better than VP9 for the same video content, so streaming companies like Netflix and YouTube enabled the codec a while ago. When I play a YouTube video in Chrome in Ubuntu 20.04 and check the stats for nerds info, it will usually show the video is played with “av01.0” codec which refers to AV1, but it’s played with software video decoding using libraries like Dav1d leveraging SIMD instructions. But ideally, you’d want hardware video decoding for lower power consumption for increased battery life, and potentially smoother videos. One good news is that Microsoft has recently announced support for AV1 GPU-accelerated hardware video decoding in Windows 10. The less good news is that support will be limited to recent and fairly powerful GPUs. So for instance, if you own mini PCs with older Intel SoC featuring integrated Intel HD/UHD graphics, AV1 hardware decoding won’t […]

Most GPU drivers found in Arm processors are known to be closed-source making it difficult and time-consuming to fix some of the bugs since everybody needs to rely on the silicon vendor to fix those for them, and they may even decide a particular bug is not important to them, so you’d be out of luck. So the developer community has long tried to reverse-engineer GPU drivers with projects like Freedreno (Qualcomm Adreno), Etnaviv (Vivante), as well as Lima and Panfrost for Arm Mali GPUs. Several years ago, Arm management was not interested at all collaborating with open-source GPU driver development for Mali GPUs, but as noted by Phoronix, Alyssa Rosenzweig, a graphics software engineer employed by Collabora, explained Panfrost development was now done in partnership with Arm during a talk at the annual X.Org Developers’ Conference (XDC 2020). A recent merge commit confirms the move with Daniel Stone, Graphics Leads at Collabora commenting To reiterate the answer from earlier […]
Intel has officially launched Tiger Lake processors for thin-and-light Laptops. The new 11th generation processors come with either Intel Iris Xe graphics or the older Intel UHD graphics, and nine processors are currently available divided into two families: UP3 with 12W to 28W configurable TDP, and UP4 with 7W to 15W configurable TDP. Manufactured with a 10nm process, the new processors are said to deliver up to 2.7x faster content creation (Photo Editing), more than 20% faster office productivity in Office 365, and more than 2x faster gaming plus streaming when comparing an Intel Core i7-1185G7 processor to AMD Ryzen 7 4800U. The new Intel Iris Xe graphics comes with up to 96 EUs and up to 16MB of L3 cache, and Intel claims it outperforms 90% of the discrete graphics usually paired with U-series processors. Tiger Lake processors also integrate a new DP4a instruction set for neural network inferencing on integrated graphics with Intel DL Boost and native support […]
