Arm Officially Supports Panfrost Open-Source Mali GPU Driver Development

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).

[...] So that means a stable Panfrost driver should be expected quite earlier, and possibly with higher quality, than if the company still had to spend time and resources on reverse-engineering.

Pagamigo: FOSS Python Script for PayPal Payments 19 comments

As part of a Free Software Foundation internship, developer Alyssa Rosenzweig has released a python3 script intended to allow users to make PayPal payments without using the proprietary ECMAScript normally associated with its usage. From the FSF's blog:

My third and final project was still more ambitious. As you may know from my work with Panfrost, the free software driver for modern Mali GPUs, I enjoy liberating critical proprietary software by decoding its internal protocols and reimplementing them in freedom. So, we looked around for latent proprietary software involved with FSF operations. Although we eat our own dog food, there was one proprietary system that could not be ignored: PayPal, which recently began requiring nonfree JavaScript. Pah. Enter Pagamigo. (In Calculus, this is formally known as a p-series.)

Pagamigo liberates the proprietary software required to donate to organizations like the FSF or the Debian Project via PayPal. Soon, the FSF Web pages that take online payments will include instructions for using Pagamigo.

Nvidia Announces $40 Billion Acquisition of Arm Holdings 20 comments

We had two submissions about this just-announced story.

Nvidia to buy Arm Holdings From SoftBank for $40 Billion

Nvidia to buy Arm Holdings from SoftBank for $40 billion

Chipmaker Nvidia has agreed to buy Arm Holdings, a designer of chips for mobile phones, from SoftBank in a deal worth $40 billion, the companies announced Sunday. The deal will include $21.5 billion in Nvidia stock and $12 billion in cash, including $2 billion payable at signing.

Softbank acquired Arm in 2016 for $31.4 billion in 2016 in one of its largest acquisitions ever. Arm is best known as the designer of an architecture used in chips in most mobile phones, including the Qualcomm chips used in most Android phones, as well as Apple's iPhone. Apple is also planning to shift its Mac computers from Intel chips to an Arm-based design.

Nvidia, whose chips are widely used to support graphics and artificial intelligence applications, including for self-driving vehicles, pledged that it would "continue Arm's open-licensing model and customer neutrality."

Interest in RISC-V set to skyrocket again.

Jensen Huang Says Nvidia-Branded ARM CPUs Are a Possibility

According to comments from Nvidia CEO Jensen Huang during a conference call yesterday, we could see Nvidia-branded CPUs in the future, setting the stage for a new level of competition with Intel and AMD.

[...] However, during yesterday's briefing, Timothy Prickett Morgan from TheNextPlatform asked Jensen Huang, "Will you actually take an implementation of something like Neoverse first and make an Nvidia-branded CPU to drive it into the data center? Will you actually make the reference chip for those who just want it and actually help them run it?"

"Well, the first of all you've made an amazing observation, which is all three options are possible," Huang responded, "[...] So now with our backing and Arm's serious backing, the world can stand on that foundation and realize that they can build server CPUs. Now, some people would like to license the cores and build a CPU themselves. Some people may decide to license the cores and ask us to build those CPUs or modify ours."

"It is not possible for one company to build every single version of them," Huang continued, "but we will have the entire network of partners around Arm that can take the architectures we come up with and depending on what's best for them, whether licensing the core, having a semi-custom chip made, or having a chip that we made, any of those any of those options are available. Any of those options are available, we're open for business and we would like the ecosystem to be as rich as possible, with as many options as possible."

European Commission Extends Probe of Nvidia's Arm Acquisition 19 comments

Nvidia Offers Concessions in EU as Arm Deal Probe Extended

The European Commission (EC) this week extended its probe of Nvidia's proposed acquisition of Arm until at least October 27 and said that Nvidia offered the EU certain concessions to[sic] in a bid to persuade the bloc's antimonopoly regulators to approve the deal. Experts say that the EU regulatory review will take considerably longer.

In a bid to make regulators approve the deal to acquire Arm, Nvidia is eager to offer various incentives to respective countries or blocs. In the U.K., the company proposed to invest 'at least' $100 million in the country's most powerful supercomputer. The EC said that it had received concessions proposal from Nvidia as well, but did not elaborate, reports Bloomberg.

Now that the probe is formally extended to October 27, the EU competition authority will request opinion from competitors and clients before determining whether to accept Nvidia's concessions, demand more or initiate a four-month long investigation, reports Reuters. Bloomberg believes that the probe will be extended further, which will give the EC some additional time to seek feedback from interested parties and figure out what it might get from Nvidia.

    Sounds like NVidia is buying them, which I honestly can't see as A Good Thing (tm) for ARM in general. So who's to say that in a month or three, whenever the deal goes through, the new owners don't support Panfrost.

      The deal could take 1-2 years, more than enough time to make progress.

      I share the skepticism about NVIDIA with their history of antagonism to free software. But, NVIDIA has already made an exception to firmware signing to allow Nouveau to be used on their Tegra SoCs, so maybe for embedded SoCs like what Mali has been used on they will continue to be less shitty toward free software.

      Alternatively, perhaps NVIDIA is abandoning Mali after acquisition of ARM, and doesn't want to support it anymore, so are influencing ARM to free it. Seems kind of doubtful, though. But, it does seem like freeing proprietary information for the first time in ARM's history, at the same time the sale of the company is announced, that the buyer would have some say in the decision.

        I'm sure NVIDIA is already planning to kill off Mali, but many of the boards with those chips will continue to be sold for at least another half decade, probably longer.

    Back in the day Nvidia had a developer similarly assist Nouveau in renaming identifiers and organizing structs to match what they use internally in the proprietary upstream but it never really amounted to anything beyond that. It's generally believed they went through that since they wanted (and still want) the upsteam FOSS driver to be just good enough to reach a GUI where users can accept their EULA and deploy proprietary drivers.

    So, while it's still quite helpful of them, I wouldn't get my hopes up.
