1 Several things in this update: the OpenPower Foundation released their
2 EULA (which is really exciting); we had
3 a last-minute decision to go to FOSDEM to meet NLNet (and meet lots
4 of nice people including someone from the EU Commission); we have new team
5 members helping out (and making really good progress).
6
7 Before we begin, however, we still have a high-priority task of
8 finding a C++/compiler developer for the NLNet-funded 3D MESA Driver
9 project. EUR 50,000 is available, tax-free: [this
10 thread](http://lists.libre-riscv.org/pipermail/libre-riscv-dev/2020-January/003302.html)
11 describes the scope, where you're pretty much at liberty to choose the
12 approach that you'd like to take.

14 ### OpenPOWER Foundation Releases the Power ISA EULA
15
16 This is a big deal: the
17 [EULA](https://openpowerfoundation.org/final-draft-of-the-power-isa-eula-released/)
18 for anyone wishing to create a Power ISA compatible processor, it's been
19 designed to be "libre-friendly." We will need to do a full review,
20 and would appreciate feedback on it, via
21 [this bug report](http://bugs.libre-riscv.org/show_bug.cgi?id=179).
22 A very quick read (like, right now): the really interesting bit is the
23 combination of a royalty-free grant (as long as you are fully
24 compliant with Power ISA) in combination with "if you initiate
25 patent litigation, you lose all rights immediately." This provides an
26 extremely strong disincentive for patent trolls to "try it on." It also
27 actively encourages contributors to make sure that their work becomes an
28 "official" part of Power, because that then gets them under the
29 "umbrella" of protection as part of this EULA.
30
31 My only concern - long-term - is the warning about Custom Extensions
32 potentially being incompatible. We remember the Altivec clash very
33 well, citing it as a historic lesson of "How Not to Manage an ISA,"
34 because both Altivec's vector extension and the one it clashed
35 with became high-profile, public, commonly used extensions,
36 and it damaged Power ISA's entire reputation and viability as a result.
37
38 With our extensions being designed *knowingly* in advance to be
39 high-profile, public, and commonly used, we absolutely have
40 to submit them as "official" extensions, or to work with the Open Power
41 Foundation to create an official "escape-sequence" namespace system
42 (ISAMUX/ISANS). As mentioned previously: anyone familiar with C++,
43 we need a hardware version of "using namespace," in its entirety.
44
45 First preliminary reading however, as Hugh kindly said privately to me,
46 there's really nothing controversial, here, and it actually looks really
47 good and extremely well-designed. More on this on
48 [Phoronix](https://www.phoronix.com/scan.php?page=news_item&px=OpenPOWER-ISA-EULA-Draft)

50 ### FOSDEM 2020
51
52 As mentioned
53 [on the list](http://lists.libre-riscv.org/pipermail/libre-riscv-dev/2020-January/003660.html)
54 we received a message from Michiel that they were financially backing over
55 *25* projects that were attending and giving talks at FOSDEM!
56 They also let everyone know that the nice people from Brussels were going
57 to be attending. At which point, I went, "ah" and scrambled like mad to
58 make sure I was there, presenting a smiling face to ensure that the nice
59 EU Commission people knew that their money was definitely being put to good
60 use.
61
62 This actually turns out to be a serious problem for the EU. My friend Phil
63 decided a few years ago to go along to one of these "Independent Grant Review"
64 processes. He basically said that not only was the quality of the applications
65 absolutely atrocious, but worse than that the people volunteering to do the
66 review - ordinary people like solicitors, office managers, farmers - had
67 precisely zero technical knowledge and couldn't tell the difference between
68 a good application, a bad application, or a deceptive application.
69
70 These problems only increase as NLNet grants get larger and more
71 numerous. Consequently, it's quite a challenge for NLNet to ensure the
72 money they've been given responsibility for reaches people who release
73 actual free software to improve real-world infrastructure for the
74 benefit of EU Citizens (and incidentally the rest of the world).
75
76 I had a brief chat with the person from the EU Commission. He was
77 delighted to be able to see the sheer number of people involved and
78 being sponsored by NLNet. I had an opportunity to express some of my
79 concerns about NLNet's relationship with the RISC-V Foundation. He
80 initially expressed puzzlement, because the EU is funding quite a lot
81 of RISC-V projects, and none of them had any issues. I asked him a
82 very simple question: "how many of those projects are simply
83 *implementing* existing RISC-V Standards?," and he replied, "all of
84 them." I then asked, "how many of those projects are *innovating*,
85 developing alternative extensions to what is dictated by the RISC-V
86 Foundation?" With the answer being "none," *that* was the point at
87 which he understood the extent of the problem. I'll publish a more
88 comprehensive update on this topic soon.
89
90 ### Meeting Other LibreSOC People
91
92 It was fantastic to meet Staf, and talk to him about the upcoming
93 test chip he'll be doing. He will be including an SR-Latch cell for
94 us, because it saves such a vast number of gates in the dependency
95 matrices if we use a D-flip-flop: 50,000 gates if we use an SR-Latch,
96 and a *quarter of a million* if we use a DFF.
97
98 I met several other people, including one who can help us develop a
99 [board support package (BSP)](http://bugs.libre-riscv.org/show_bug.cgi?id=164).
100 Also, we got a chance to talk to several people with cross-over skillsets.
101
102 This alone was worth the time to go to FOSDEM this year. Now we have
103 to make sure to plan properly in advance, to put in some papers at
104 appropriate conferences. We really need to organise a proper
105 conference where everyone meets up.
106
107 ### New Members
108
109 We created an [about us](http://libre-riscv.org/about_us) page for
110 members -- if you'd like to help, check out the [How can I
111 help?](http://libre-riscv.org/) section of the website.
112
113 We now hoave four new people who are contributing: Cole, Veera, Yehowshua,
114 and Michael. Veera is a sysadmin and I would be delighted to get some
115 help managing the server. In particular I would like to install `public-inbox`
116 but it requires `exim4` and `mailman` to be converted to `Maildir`. This is
117 the kind of thing that would be great to hand over to another sysadmin.
118
119 Cole just loves the idea of what we're doing and wants to learn, so
120 what I've asked him to do is simply to follow instructions and
121 tutorials, and give us feedback on whether they're clear. If not,
122 that's a problem that needs to be fixed -- it's precisely his *lack*
123 of experience that is absolutely perfect for testing that.
124
125 Yehowshua -- a friend of Michael -- got in touch around the time of the
126 last update, and he's been helping find funding. As he is at Georgia Tech,
127 he will be applying for the LAUNCH-X Programme, funded initially by my
128 old boss, Chris Klaus. Chris has been really helpful here, and he's really
129 delighted to be able to help other Georgia Tech Alumni. Yehowshua has
130 also been encouraging and helping with a redesign of the website CSS,
131 and has been instrumental in a major rewrite of the wording.
132
133 Michael has just jumped straight in to the processor design. Yehowshua
134 tells me he first met Michael as he was sitting in a cafe with an FPGA
135 board attached to his laptop. He's another of these extremely rare
136 self-motivated, self-taught, "auto-learner" types who are worth their
137 weight in gold. He's currently helping with the
138 [Dynamic SIMD partitioner](http://bugs.libre-riscv.org/show_bug.cgi?id=132)
139 which we will need to do a special update about, at some point.
140
141 One particularly fascinating common theme between all of us turns out
142 to be music, maths, and high-coordination sports. Yehowshua loves
143 skate-boarding, and I love rollerblading, for example.
144
145 One very interesting thing came out of the contact with Georgia Tech's
146 CREATE-X Programme: we are looking to create a Public Benefit Corporation.
147 More on this later, however it became clear to us that we need good
148 "communicators" at least as much as need more "programmers," although we do still
149 urgently need a C++ compiler type person for the
150 [MESA 3D Driver](https://libre-riscv.org/nlnet_2019_amdvlk_port/).
151 We need entrepreneurs -- especially undergraduates from Georgia Tech -- willing
152 to take on the responsibility for going out and finding, meeting, and talking to
153 clients and customers, coming up with ideas, and giving us, as "engineers,"
154 the feedback we need to target the processor at an actual market.
155
156 ### Other Stuff
157
158 The extra NLNet budgets are helping, as is the continued sponsorship
159 from Purism. I am beginning to get slightly overloaded with the
160 managerial and bureaucratic tasks, combined with the "Engineering"
161 tasks that, as is always the case, require 100% sustained week-long
162 focus. Making all these things compatible is a challenge.
163
164 I still have to coordinate the NLNet tasks for each of the Memoranda
165 of Understanding, at which point people can then get paid for
166 completing the associated tasks. I can't quite get over the fact that
167 NLNet was happy to allocate such a huge amount of money to this
168 project, it's amazing, humbling, and a huge responsibility.
169
170 Also, we got word that the 180 nm tape-outs (one in March 2020, one in
171 October 2020) are actually subsidised. In addition, we have *verbal*
172 informal confirmation that some proprietary cell libraries are about
173 to be announced as being libre-licensed. This is particularly
174 fascinating.
175
176 Right now, when it comes to creating Libre ASICs, people basically
177 give up and don't even bother because it's so ridiculously costly --
178 no individual Libre ASIC developer could possibly imagine themselves
179 contributing to, let alone raising the multi-million funds for, say, a
180 4 GHz 10-stage 12-core SMP multi-issue processor, so they don't even
181 bother to design or release anything that *could* be part of such a
182 design. Yet, reading between the lines, we can hypothesise that
183 various "noises" about how hardware is proprietary, and how difficult
184 it is to do Libre ASICs, are starting to yield some results, as
185 various large companies who shall remain nameless for now are quietly
186 and subtly waving around very large amounts of cash in front of the
187 noses of Foundries, tempting them to release things like cell
188 libraries under Libre licenses. Given that the U.S. trade war has
189 recently caused a whopping **12%** drop in [ASIC
190 sales](https://hardware.slashdot.org/story/20/02/07/2157253/chip-industry-had-worst-sales-year-since-dot-com-bubble-burst),
191 with U.S. ASIC sales dropping **24%**, foundries might be quite open
192 to large up-front cash deals.
193
194 Anyway, as always, if you'd like to help out (and actually receive
195 money for doing so), we have a nice shiny new section [on the
196 website](https://libre-riscv.org/), "How can I help?" and there is a
197 heck of a lot to do. Feel free to get in touch, any time.
