SL_01_002 - Adding RVV assembly to dav1d

• Diversity of hardware with RVV 1.0!
• K230 has VLEN=128, SpacmiT K1 has VLEN=256
• What does this mean for writing vector optimizations?
• Diversity of hardware with RVV 1.0!
• K230 has VLEN=128, SpacmiT K1 has VLEN=256
• What does this mean for writing vector optimizations?
• Algorithms that use *less* than a full VLEN are essentially tail only
• The blend_w4 routine operates on blocks 4-wide and N-tall
• Optimal throughput needs appropriately set LMUL

DevInfra WG Collaboration

• Goal: Provide weekly drops of SD images that “just work” on currently available dev board hardware (RVV 1.0 only): K230, BPI-F3, ROMA II
  • Potential to build with exact CFLAGS matching hardware, e.g.,
    -march=rv64gcv --riscv-v-vector-bits-min=256
  • This would produce optimized builds for all packages
• Use vendor provided image (u-boot, opensbi, kernel)
• Replace rootfs with gentoo image
• Future work, could rebuild kernel using more optimizations

• Potential to build with other options
• Gentoo supports glibc and musl, OpenRC and systemd
• Can provide a head (Desktop Environment) for ROMA II laptop images

Distro and Integration Deep Dive

• The distro integration group hosts open discussions about the software needs common to all major Linux distros, Android, and bespoke distros used on embedded devices.  
  1. General discussions and questions about viability of builds with low RAM that aren’t capable of updating packages etc. Not something RISE should dictate. 
  2. In General RISE is contributing to the Open Source Projects and there will not be any requirements/mandates by RISE. any requirements are left it up to the companies and their product offerings.  
• “Why is it you’re all insistent on having ACPI support?”
• “What is the minimum amount of RAM a board should have?”
• This group makes its meetings  open to the public (the meeting link is on the groups wiki page).
• Ensures open collaboration modeled after other libre software projects (Debian, Osmocom, etc). 
• The community sees the “total cost” of design decisions, not just the hardware ones.
• Recently this has driven two major areas of discussion: 
• Ensure a consistent boot flow (installation portability across distros)
• Responsibility for code updates below the OS (e.g. Who is on the hook for security bugs in OpenSBI?)

Website and Blog Update

• HAPPY ANNIVERSARY RISE PROJECT!
• Website updated, now with a blog, events page, separated topic pages, dedicated join page
• Bug reports and comments welcome.

Appendix

...

• Tensorflow for RISC-V (email sent to libraries-runtimes WG)
• If yes, what is the latest status? 
• We are getting asked questions Questions regarding the availability of Tensorflow on RISC-V
• Tried to compile Tensorflow within Ventana and things fail due to missing support for Bazel
• Is anyone from RISE or any upstream company working on Tensorflow? If no one is working on Tensorflow from RISE, can we make this an RFP and get some bids as Tensorflow for RISC-V is a pretty important framework for AI/ML
• x264 for RISC-V discussion
• Bytedance team started work on x264 porting and optimization with RVV1.0
• Repo located here https://code.videolan.org/yintong.ustc/x-264-bd-ventana
• Is anyone from RISE or upstream working on x264? Bytedance would like to collaborate with other work if any
• An open discussion occured around Bazel, and RISC-V, and what is available. After the discussion it was determined that the group could continue going forward and see what the next level of errors would be. Is anyone from RISE or upstream working on x264? Bytedance would like to collaborate with other work if any

• Work to enable RISC-V support for RISE high priority projects [1]
• Find ecosystem dependencies on other WGs, file and fix bugs upstream
• Document best practices, publicize RISE priorities, community outreach
• Solve enablement problems where developers are. Need to unblock existing projects

• This was addedHEREnew sections labeled contracts and payments are now on the RFP wiki page.
• RFP postings should include LF/RISE contract text and requirements if we expect vendors to use ours
• Along with statements that we don’t accept vendor-written contracts
• WG Leads- if you create new documents in your WG folders and do not assign them to RISE PMO you will be responsible for granting permissions.

• GCC-14 release likely in May
• Initial release with vector support
• Many other code generation improvements, extension support, etc
• Many things already queued up for gcc-15
• Leads to same problem we had last year – a year delay between code going into the tree and the actual release
• Likely resulting in a optimization coordination branch again
• 20 projects identified for 1H2024
• 10 are already at development completion, 8 in progress, 1 under investigation, 1 not started
• 6 already upstreamed (ie, in gcc-14), rest are on hold waiting for development window to reopen

Compilers and Toolchains Deep Dive – LLVM Status

• LLVM Projects identified for 1H2024 – only 6, like more that should be added to the page.
• CRC – looks like Joe Faulls (Imagination Technologies) has picked this up from Mikhail.  MR filed and is undergoing review.
• X264 if-conversion.  2 of 3 blockers resolved.  Still hashing through one notable issue in the generic if-conversion code
• Stack Clash – Just getting started, engineer’s 1st LLVM project
• Shrink Wrapping – Just getting started.
• Overly aggressive if-conversion in some cases?
