Go: todos: porta para RISC-V

Criado em 6 set. 2018  ·  219Comentários  ·  Fonte: golang/go

Este problema serve para rastrear a porta para a arquitetura RISC-V. Há uma porta out-of-tree em https://github.com/riscv/riscv-go baseada em Go 1.8 que - de acordo com riscv / riscv-go # 19 - não é mais mantida e precisaria de algum trabalho para ser atualizado para a dica Go atual.

Consulte também https://golang.org/cl/106256#message -2d9a5c5b89ad55b8b7999f794983f993649232c8 e https://groups.google.com/forum/#!searchin/golang -dev / RISC% 7 Csort: date / golang-dev / VpsyGdi -sQQ / FMu6IB_2CwAJ em que @josharian resumiu o estado atual da porta existente.

Os valores GOARCH riscv e riscv64 foram reservados em https://golang.org/cl/106256. Esses valores já são usados ​​pelo gccgo. Alterações adicionais foram feitas em debug/elf (https://golang.org/cl/107339), cmd/cgo (https://golang.org/cl/110066), cmd/dist e cmd/types (https://golang.org/cl/118618) para poder gerar arquivos de definição de tipo no pacote x/sys/unix (https://golang.org/cl/ 133735).

Comentários muito úteis

Parece que decolamos 🚀Carregado de testes com falha, mas nada de real interesse e parece relativamente simples de corrigir.

Os commits mais recentes parecem corrigir a maioria dos problemas e estou executando programas go relativamente grandes no qemu-system-riscv.

Vocês podem testar e fornecer algum feedback?

A alteração https://golang.org/cl/133735 menciona este problema: unix: add support for linux/riscv64

/ cc como mantenedor do Fedora / RISC-V.

Eu ficaria feliz em incluir. isso na distribuição (depois de compilar) e faça alguns testes.

Obrigado por levantar isso.

Alguém sabe onde posso conseguir o hardware para testar?

Esforços de nova casa, CPU e FGPA estão em andamento usando risc-v.
Um grande ponto de viragem e oportunidade para programadores golang.

Aqui está o principal feed de notícias sobre tudo isso:
https://riscv.org/news/

@ gedw99 No momento, a SiFive é a única empresa que produziu uma placa de desenvolvimento RISC-V ( HiFive Unleashed ). Uma ressalva a este conselho é o preço, que gira em torno de US $ 1.000.

cc @ganshun e @rjoleary nós três também estávamos prestes a começar a procurar uma porta. Temos algumas placas SiFive para experimentar.

@hugelgupf , quando você estiver longe o suficiente para querer um construtor configurado, registre um bug e me copie e eu ficaria mais do que feliz em ajudar.

Recentemente, comecei a usar o qemu para executar uma compilação riscv fedora. Aqui estão os links caso seja útil para desenvolver sem uma placa.

https://github.com/riscv/riscv-qemu
https://fedoraproject.org/wiki/Architectures/RISC-V/Installing#Download_the_latest_disk_image
https://fedoraproject.org/wiki/Architectures/RISC-V/Installing#Boot_under_qemu

Usando dnf install gccgo consegui construir e executar aplicativos go em emulação.

Apenas lembre que o RISC-V é compatível com as versões lançadas do QEMU e libvirt, o que facilita a configuração de várias VMs com gerenciamento. Veja: https://fedoraproject.org/wiki/Architectures/RISC-V/Installing#Boot_with_libvirt

Observe que nosso libffi não oferece suporte a encerramentos Go, portanto, algumas funcionalidades não funcionam. O patch já existe, mas preciso fazer um backport para nossa versão libffi. Devo dar prioridade a isso?

FWIW, comecei a rebasear o https://github.com/riscv/go-riscv baseado em Go 1.18 para a dica Go atual em https://github.com/tklauser/go-riscv. Atualmente, ele se baseia em linux/amd64 mas ainda não pode gerar riscv64 binários válidos.

Atualmente, não tenho tempo e recursos para realmente levá-lo adiante, mas talvez alguém que esteja trabalhando nisso possa achar útil.

Acabei de ver que aparentemente você pode executar RISC-V na nuvem por meio de uma instância FPGA AWS:

https://www.cnx-software.com/2017/02/22/amazon-ec2-f1-instances-put-xilinx-virtex-ultrascale-fpga-boards-in-the-cloud/

Essa pode ser uma possível estratégia de construtor temporária.

@bradfitz https://fires.im/ é uma implantação risc-v em aws fpgas, mas a implementação risc-v subjacente só roda até algo como 100mhz. Trabalhar com uma equipe que está fazendo pesquisas nessa área parece ser a norma. Até agora, a emulação tem sido de longe o melhor desempenho.

O QEMU suporta até 8 núcleos (MTTCG - multi-threaded TCG), o que é ótimo se você puder compilar em paralelo.

Como alternativa, entre em contato com Palmer Dabbelt da SiFive e peça uma placa SiFive HiFive Unleashed gratuita (vários projetos receberam uma para esforços de portabilidade).

Mudança https://golang.org/cl/157899 menciona este problema: unix: use Renameat2 to implement Renameat on linux/riscv64

A mudança https://golang.org/cl/157900 menciona este problema: unix: use int8 for RawSockaddrUnix.Path on linux/riscv64

A mudança https://golang.org/cl/157901 menciona este problema: unix: add assembly for riscv64 syscalls

Problema para configurar um construtor RISC-V baseado em qemu: # 30262

Mudança https://golang.org/cl/170298 menciona este problema: cpu: add basic support for GOARCH=riscv64

O port riscv qemu funciona muito bem e o Fedora tem feito progressos, tornando-o uma distro normal. Estou acompanhando o estado de riscv aqui: https://github.com/marcopeereboom/riscv-bringup-doco e talvez tenha algumas dicas úteis para algumas pessoas. A questão é que qemu é um bom alvo de desenvolvimento e você realmente não precisa de metal para progredir.

A última peça que faltava no quebra-cabeça para mim é ir embora. https://github.com/riscv/riscv-go parece funcionar, mas é 1.8 e quase tudo em que trabalho mudou para 1.12 e usa módulos. Eu olhei para portar a base de código 1.8 para uma versão de cada vez e não parece muito difícil, mas não tenho tempo para sentar lá e insistir nisso (refrão familiar).

Animado para ver esse avanço.

Um amigo meu fez o Go 1.12 funcionar. Ele bifurcou https://github.com/riscv/riscv-go e o atualizou para 1.12. Parece produzir binários que funcionam, mas sem dúvida ainda existem alguns bugs à espreita.

Parece ser capaz de construir binários, mas quando é compilado de forma cruzada, ainda não funciona.

Veja o repo aqui: https://github.com/4a6f656c/riscv-go

Seria ótimo se parte disso pudesse começar a ser portado para o master para testes mais difundidos.

Um amigo meu fez o Go 1.12 funcionar.

Yay!

Ele também puxou as mudanças ainda não consolidadas de Stefan O'Rear?

Parece ser capaz de construir binários, mas quando é compilado de forma cruzada, ainda não funciona.

Não olhei o código, mas seria bom executar o compilador no detector de corrida. (Ou seja, execute em amd64 com -race, construindo para risc-v.) Os back-ends obj asm devem ser concorrentes a partir de 1.9.

Seria ótimo se parte disso pudesse começar a ser portado para o master para testes mais difundidos.

Eu suponho que você quer dizer upstream. Estamos em um congelamento de código agora. Consulte https://github.com/golang/go/wiki/Go-Release-Cycle. O ideal é que a adição de risc-v ao master ocorresse logo no início do ciclo, começando por volta de 1º de agosto.

Observe que não podemos aceitar código a menos que todos os autores tenham assinado um CLA (o que é parte da razão pela qual ainda não o examinei).

Joel é ex Google e fez vários commits para Go. Tenho certeza de que não haverá problema com isso.

Não sabia que estávamos congelando o código, mas isso é realmente muito bom. Dessa forma, podemos resolver os últimos bits e ver se podemos colocá-los assim que descongelar e, então, teremos um ciclo de lançamento inteiro para acertar. Emocionante!

Tem um link?

Eu deveria ter verificado seu perfil no GitHub. É bom ver o nome dele novamente. :)

Sim, de fato.

Em um mundo ideal, também, dividiríamos o upstreaming em uma série de commits, para ajudar na revisão. Vale a pena verificar como outras arquiteturas concluídas foram desenvolvidas (por exemplo, arm64, wasm).

Tem um link?

https://review.gerrithub.io/q/project : riscv / riscv-go

Alguns de nós com interesse em fazer isso acontecer estão saindo em # risc-v no Gophers Slack. Adoraríamos ter mais gente se juntando a nós lá e nos ajudar.

https://invite.slack.golangbridge.org

Estou feliz por estar envolvido, mas intencionalmente não sou um usuário do Slack. Se vocês começarem a usar outro meio também (problemas com o github, uma lista de e-mails), por favor me avisem.

Excluí o slack em todos os meus dispositivos.

Certamente precisaríamos de ajuda com os bugs restantes. Parece que algumas syscalls do Linux falham ou não estão implementadas. Esses bugs não devem ser muito difíceis de localizar e corrigir. Podemos até usar o GitHub para rastrear bugs 😏

Pequena atualização. A inicialização agora funciona de maneira confiável e pode-se construir por conta própria no QEMU riscv. Parece haver um bug com bloqueios ou com o QEMU causando alguns travamentos divertidos e estamos examinando esses problemas. Se alguém tiver as habilidades para ajudar, adoraríamos ouvir de você.

As etapas básicas estão em uma máquina com go1.4 ou um novo go instalado:

GOOS=linux GOARCH=riscv ./bootstrap.sh

Copie o arquivo tbz para o host riscv QEMU, descompacte-o e, em seguida, compile por conta própria:

GOGC=off GOROOT_^COTSTRAP=~/build/go-linux-riscv-bootstrap/ ./all.bash

Observação: toda a compilação foi feita a partir deste repo: https://github.com/4a6f656c/riscv-go

Nem sempre funciona e pode ter que ser reiniciado, mas eventualmente será compilado. Tentei construir alguns aplicativos maiores e eles agem da mesma forma. Trabalhe um pouco e então dê um crash aleatório. Certamente se parecem com corridas.

Sem usar GOGC=off , recebo o seguinte erro:

Criei o bootstrap no Mac com Go 1.12.5.

Depois de construí-lo com sucesso (nunca falhou), executei os testes e encontrei alguns problemas. Cole aqui como acompanhamento do documento:

Agora, tentarei analisar a construção de alguns aplicativos de teste e esses erros.

Eu editei seu comentário para colocar o log longo em um bloco de "Detalhes".

Essa falha, que também aparece em outro lugar, mostra claramente que há algo errado com a implementação de atomic.Cas . Como isso poderia facilmente causar condições de corrida em outros lugares, você precisa consertar isso primeiro.

Seguindo, para a maioria, talvez todos, os alvos, atomic.Cas é implementado no próprio compilador.

Talvez https://review.gerrithub.io/c/riscv/riscv-go/+/353663 possa ajudar. (E se isso acontecer, ele definitivamente está olhando para os outros CLs ainda não mesclados na lista vinculada acima.)

Em primeiro lugar, incrível!
Em segundo lugar, a porta suporta a variante RISC-V de 32 bits?

Eu tenho um hardware capaz de Linux de 32 bits sintetizado em um FPGA no qual quero experimentar o golang.

Não, isso não oferece suporte a riscv32.

Joel e eu reduzimos isso ao bloqueio no QEMU. Escrevemos vários programas de teste menores para reproduzir o bug facilmente. Vou escrever os problemas de bloqueio / atômico no repositório QEMU.

Se alguém tiver um hardware real para testar, isso ajudaria a ver se é QEMU ou não.

Quando corrigirmos esses problemas, o Go poderá estar em muito boa forma, na verdade.

Isso é exatamente correto.

@marcopeereboom deixe-me saber se há soluções alternativas ao construir no Qemu e onde seguir esses relatórios. Estou prestes a obter uma placa SiFive Unleashed em breve, então seremos capazes de construir em ferro real para remover essas variáveis.

Eu tenho uma placa riscv64, mas não há muito tempo, se você me der um script de shell, irei executá-lo para você (no Alpine Linux).

Bom trabalho Joel ( @ 4a6f656c , presumo?) E @marcopeereboom!

Uma pequena observação: o GOARCH reservado para RISCV de 64 bits é riscv64 . riscv está reservado para RISCV de 32 bits, consulte https://golang.org/cl/106256

Tomei a liberdade de fazer um fork da árvore do Joel e renomear (mais algumas outras correções de limpeza). Você pode encontrar a árvore em https://github.com/tklauser/riscv-go/commits/riscv64dev. Infelizmente, não consigo enviar um PR contra o fork do Joel, mas sinta-se à vontade para puxar os patches que considerar úteis.

Também tentarei atualizar meu branch riscv em https://github.com/tklauser/go/commits/riscv (que rastreia o gotip) com as alterações de seu branch e possivelmente https://review.gerrithub.io/c / riscv / riscv-go / + / 353663 mais outros patches formam esta série.

Ei, @tklauser Joel já havia empurrado a renomeação. Certamente aceitaremos sua ajuda e se você tiver PRs adicionais no topo da árvore atual, informe-nos. E obrigado por fazer um branch atual, que será útil.

Eu tenho uma placa riscv64, mas não há muito tempo, se você me der um script de shell, irei executá-lo para você (no Alpine Linux).

Eu praticamente colei as instruções para construí-lo. Construir go, ao contrário do espaço do usuário e dos kernels, é trivial.

Eu combinei os patches @ 4a6f656c . Tive que ajustar alguns conflitos e também martelar em uma mudança em uma função onde a geração dinâmica usava um syscall indisponível. Os arquivos estão em meu fork como um teste temporário (https://github.com/carlosedp/riscv-go). No momento, estou executando os testes e aparentemente vejo menos erros ( @josharian, esses erros CAS desapareceram).

Postará o teste em breve.

E depois de brincar mais um pouco com o código de teste, estamos convencidos de que é QEMU ou o kernel. Estou inclinado para o código atômico sendo eliminado e o estado de perda da CPU de alguma forma. Eu escrevi um aplicativo encadeado em C que usa um CAS muito semelhante ao de Go e o transformou em um mutex de pobre homem. A seção crítica apenas incrementa um global e no final da execução o valor esperado é comparado com o valor real.

Os resultados são que quando executado no linux dentro do QEMU com threads e / ou iterações suficientes ele perde alguns bloqueios. Quando executado com qemu-riscv sem um kernel, ele é executado indefinidamente sem falhas.
Código para este teste: https://gist.github.com/marcopeereboom/1a3b62a89f81b2ed341082cedaef4874

Mais preocupante é que alguns atômicos do gcc também falham em um teste semelhante. Código: https://gist.github.com/marcopeereboom/1e40d4baffdcc9a2066310d770f5ac12

Tentamos adicionar algumas cercas extras, mas não surtiu efeito. Código:
https://gist.github.com/marcopeereboom/4357c59b57dc998a58d37817d59f99b0

A desmontagem parece correta e, quando comparada às especificações, parece que deve funcionar.

Eu sei que esses trechos não vão ganhar o concurso estadual, mas eles são pequenos o suficiente para testes rápidos. Estou debatendo onde registrar esses problemas. Alguém tem alguma opinião? Kernel Linux, QEMU?

Tentou construir seu material de go. O bootstrap correu bem, mas falhou cedo ao fazer a compilação completa:

https://paste.sr.ht/~sircmpwn/3a76f2ee0b914eccf2cc70fc6ca6b7a75de547a3

Observe, estou usando musl libc para bootstrapping e em riscv64.

Às vezes funciona. Pode ter que brincar um pouco com as iterações e threads em seu hardware.

Gastei alguns minutos ajustando-o e ainda não fiz isso falhar. Se o problema for entre o kernel e o qemu, o kernel parece bem seguro.

Isso é o que eu vejo. Isso explica os problemas de go também.

Você pode compartilhar o kernel do qemu e do Linux que está executando?

Estou executando o Fedora todas as noites com Kernel 5.1.0-rc7-00005-g83a50840e72a.

Aqui estão os resultados do teste executado para Go após as fusões:

Faça algo como: gcc x.c -pthread . O aviso é por causa de um hack terrível.

Estou em uma placa riscv64 real, HiFive Unleashed. O kernel é 4.20-rc4 mais este patch:

Ah, hardware de verdade. Deixe-me levantar o código CAS exato desde o início (ele faz alguns loops extras no conjunto) e dar a você uma coisa nova para testar. Além disso, você pode criar threads como 100 e adicionar um ou dois zeros às iterações? O hardware real pode ter que ser batido com mais força.

Você pode tentar os outros 2 testes também que vinculei anteriormente?

Execute-o várias vezes ou até mesmo em um loop apertado. Além disso, brinque um pouco com o #define.

Além disso, você pode criar threads como 100 e adicionar um ou dois zeros às iterações?

Eu te dei 50 threads e um zero extra, este hardware não é o mais rápido e eu não sou feito de ciclos: wink:

Eu construí com sucesso o projeto gojsontoyaml para testar o Go 1.12 no Risc-V Qemu. Em algumas ações como go get . , tive que executar com GOGC = off ou obteria erros (listados abaixo).

Se eu apenas fizer go get . , recebo o seguinte erro:

Você está no irc ou no teclado para que não poluamos mais esse problema com isso?

Oh, desculpe, meu sshd não tem suporte para ed25519. Você tem uma chave RSA? Estou ddevault no freenode.

CC @ palmer-dabbelt @ jim-wilson @ alistair23

Se houver problemas com QEMU, kernel, glibc ou conjunto de ferramentas, essas pessoas (ou seja, mantenedores) são as melhores pessoas para ajudar.

Sim, deixe-me saber se você encontrar um problema com RISC-V QEMU e eu posso investigar.

@ alistair23 tente executar o seguinte no RISC-V QEMU:

https://gist.github.com/4a6f656c/8433032a3f70893a278259f8108aad90

https://gist.github.com/4a6f656c/d883091f5ca811822720213be343a75a

Eles podem precisar ser executados algumas vezes, mas parecem falhar no qemu, mas me disseram que funcionam corretamente em hardware real.

Tentei fazer isso e não consegui reproduzir o problema. Tentei hardware, sistema qemu e usuário qemu, e todos funcionaram. Mas talvez você tenha uma versão diferente de algo, ou tenha usado opções de compilador diferentes, etc.

@ jim-wilson você usou bbl ou opensbi?

Você também pode colar as versões de várias coisas que tentou?

Usei um sistema Fedora Core 30 rodando em hardware para compilar os dois casos de teste. Experimentei os binários no hardware e funcionaram. Eu os testei com o qemu do usuário e do sistema, usando um qemu riscv-qemu e um qemu.org upstream, e funcionou para mim em todos os quatro casos.

FC30 usa bbl.

@ jim-wilson você tentou aumentar a variável TCOUNT para mais tópicos? Às vezes, no Qemu com 4 threads ele funciona, mas com algo em torno de 40 threads ele consome dados. No hardware, deve funcionar perfeitamente.

Nada neste relatório de bug menciona TCOUNT. Eu tentei aumentá-lo para 40 e agora ele está falhando usando o sistema qemu com um antigo riscv-qemu e um topo da árvore qemu.org. Ele ainda funciona na minha placa HiFive Unleashed. E funciona com um qemu de modo de usuário, tanto antigo quanto novo, embora esteja usando uma glibc mais antiga.

Então, talvez um bug do kernel do linux ou um bug do qemu do sistema, e eu não sou um especialista em nenhum deles.

@marcopeereboom mencionou lá para brincar com threads e iterações, é isso que TCOUNT faz. Aparentemente, é um bug do Qemu. Estou apenas limpando algumas coisas e postarei isso na lista de e-mails do Qemu para que @ alistair23 e @ palmer-dabbelt possam ajudar a verificar isso.

Sim, estamos realmente inclinados a um bug do sistema qemu. Vou tentar escrever um problema, mas eles usam um rastreador de bug bobo.

@marcopeereboom , Palmer apontou para escrever para a lista de discussão em [email protected] (https://lists.nongnu.org/mailman/listinfo/qemu-riscv) descrevendo o bug.

Parece que decolamos 🚀Carregado de testes com falha, mas nada de real interesse e parece relativamente simples de corrigir.

Os commits mais recentes parecem corrigir a maioria dos problemas e estou executando programas go relativamente grandes no qemu-system-riscv.

Vocês podem testar e fornecer algum feedback?

Ainda vejo alguns problemas relacionados ao GC, agora na placa Unleashed. Eu reconstruí meu bootstrap no meu Mac, transferi-o para o quadro e verifiquei a última árvore.

Tentei criar go-jsonnet e recebi este erro:

Portanto, esse erro está fora de questão. Eu vi no bolt db. Essa árvore não está bloqueada, então tentaremos atualizá-la mais cedo ou mais tarde.

Atualização rápida de status.

Existem alguns problemas do compilador / SSA que ainda precisam ser rastreados e talvez algum polimento adicional, mas isso é tudo. Devemos estar bem saudáveis ​​aqui nas próximas semanas e, portanto, no segundo em que a árvore for aberta, podemos criar uma solicitação pull.

O que este código NÃO faz é riscv de 32 bits. As diferenças de código devem ser bem triviais, mas alguém precisa fazer o trabalho. Então, se você quiser ajudar e se preocupar com 32 bits, essa é a próxima tarefa em mãos.

Atualização rápida de status.

Estou muito animado com este trabalho. Obrigado por fazer isso.

Existem alguns problemas do compilador / SSA que ainda precisam ser rastreados e talvez algum polimento adicional, mas isso é tudo. Devemos estar bem saudáveis ​​aqui nas próximas semanas e, portanto, no segundo em que a árvore for aberta, podemos criar uma solicitação pull.

Por favor, crie uma solicitação pull assim que a porta estiver pronta para que possa ser revisada e pronta para mesclar quando a árvore for aberta. A revisão de uma nova porta leva um tempo considerável e provavelmente resultará em alterações que devem ser integradas antes da fusão.

Isso se deve à falta de wrappers de syscall de montagem para linux/riscv64 em x/sys/unix . Não os adicionamos ainda porque a sintaxe do assembly para riscv64 ainda não é considerada final, consulte a discussão em https://golang.org/cl/157901. Abandonei o CL por enquanto, mas assim que a porta riscv64 for enviada para revisão e a sintaxe do assembly for considerada estável, podemos ressuscitar o referido CL.

Esse repositório está aberto, então se você quiser :-)

Esse código usa mod.

@marcopeereboom O que você quer dizer com "mod"?

@carlosedp O código que você está construindo, que falha, está usando módulos, o que significa que está baixando o pacote golang.org/x/sys/unix para construir da Internet ou de algum cache de módulo. Ele não está usando sua variante específica do riscv64 de golang.org/x/sys/unix.

Eu construí o pacote x/sys mais recente com instruções Risc-V ASM, substituí-o no meu repo e ele testou e construiu com sucesso o aplicativo que eu estava vendo os problemas de GC anteriormente.

A fusão está em https://github.com/carlosedp/sys/tree/riscv64

Eu o clonado em meu $GOPATH/src/golang.org/x/sys e copiado para '$ GOPATH / pkg / mod / golang.org / x / sys ....' onde os módulos go são baixados agora.

$ GOOS=linux GOARCH=riscv64 go test
PASS
ok      golang.org/x/sys/unix   0.658s

Um aplicativo como o Go-Jsonnet, que antes apresentava falhas, agora cria e executa:

$ go build ./cmd/jsonnet/

$ cd cmd/jsonnet
$ go test
PASS
ok      github.com/google/go-jsonnet/cmd/jsonnet    0.015s

Mudança https://golang.org/cl/177799 menciona este problema: unix: provide linux/riscv64 assembly for syscalls

Criei com sucesso o Prometheus no Unleashed.

Tive que adicionar suporte ao módulo x / net. Já enviado ao Gerrit em: https://go-review.googlesource.com/c/net/+/177997

A alteração do Prometheus está no meu repositório (https://github.com/carlosedp/prometheus/tree/riscv64). Eu também tive que ligar para o pacote RiscV x / sys.

Fora isso, construiu bem.

Todos os testes agora devem passar.

A mudança https://golang.org/cl/177997 menciona este problema: ipv4, ipv6, internal/socket: add riscv64 support

Ainda estou vendo testes com falha em runtime . cmd/go está falhando com o tempo limite, mesmo aumentando-o, ele falha. Detalhes como visto abaixo:

@carlosedp todos os testes de biblioteca padrão passam aqui (há cerca de três em test/ que ainda estão falhando), no entanto, você provavelmente precisará aumentar GO_TEST_TIMEOUT_SCALE , especialmente se estiver executando em um dispositivo de E / S lento:

GOROOT_BOOTSTRAP=... GO_TEST_TIMEOUT_SCALE=5 ./all.bash

Obrigado pela dica sobre a variável @ 4a6f656c . Depois de ajustá-lo e consertar meu servidor de sistema de arquivos NFS (tinha erros de bloqueio), ele funcionou 100% (com as exceções em test/ como você mencionou.

Uma pergunta, porém, quão difícil é implementar as funções necessárias para CGO em src/runtime/cgo ? Uma compilação que experimentei reclamou de não encontrar _cgo_sys_thread_start e está implementada nos arquivos específicos do ARCH. Alguma dica?

Uma pergunta, porém, quão difícil é implementar as funções necessárias para CGO em src / runtime / cgo? Uma compilação que experimentei reclamou por não encontrar _cgo_sys_thread_start e está implementada nos arquivos específicos do ARCH. Alguma dica?

Você provavelmente pode apenas copiar runtime / cgo / gcc_linux_amd64.c para runtime / gcc_linux_riscv64.c. Dê uma olhada, mas não vejo nenhuma razão óbvia que não funcione. (Sim, isso deve ser um pouco consolidado.)

A questão mais interessante é runtime / cgo / asm_riscv64.s. Isso também deve ser muito simples, mas terá que ser escrito. Veja os arquivos existentes.

Acabei de enviar um branch que está mesclado com a dica Go em 2d7cb295 e contém uma variedade de correções. Todos os testes agora passam:

Incrível @ 4a6f656c , estou trabalhando no suporte CGO. Eu acredito que estou perto.

Alguém pode recomendar hardware? Desculpe perguntar neste tópico, mas estamos construindo sistemas baseados em golang para o governo, e o ISA RISC-V é perfeito porque é seguro, ao contrário de intel, braço etc.
Queremos fazer alguns testes de protótipo e conectá-lo ao processo de CI com outras placas incorporadas.

É fantástico, aliás, que a equipe golang está apoiando RISC-V

@ gedw99 por enquanto, para rodar o Linux você precisa da placa SiFive HiFive Unleashed. Acredito que ainda seja o único hardware disponível.

Comecei a implementar alguns arquivos para obter suporte para CGO, mas fiquei preso em alguns problemas. Os arquivos estão em um branch em meu fork (https://github.com/carlosedp/riscv-go/tree/riscv-cgo), se alguém pudesse dar uma olhada.

Eu dei um pequeno exemplo para testar o CGO:

// cgo.go
package main

import "C"

func test() {
}

// main.go
package main

func main() {
        test()
}

Executar CGO_ENABLED=1 go build . nele dá o erro:

$ CGO_ENABLED=1 go build .

Uma pergunta, por que estou recebendo esses erros:

$ CGO_ENABLED = 1 vá construir.

runtime / cgo

gcc_riscv64.S: Mensagens do Assembler:
gcc_riscv64.S: 34: Erro: opcode não reconhecido mov x18,x10' gcc_riscv64.S:35: Error: unrecognized opcode mov x19, x11 '
gcc_riscv64.S: 36: Erro: opcode não reconhecido `mov x10, x12 '

O montador RISC-V suporta "mv" e "move", mas não "mov".

Jim

Ai obrigado @ jim-wilson eu consertei essa parte mas encontrei outros problemas que não sei como consertar. Veja meu último comentário. Eu também empurrei o que fiz para o meu garfo ... se alguém pudesse dar uma olhada. Talvez haja mais funções exigidas pelo CGO que não considerei.

@carlosedp Eu não olhei o código-fonte, mas parece que você precisa suportar a realocação (R_ADDR)/8 em elfreloc1 em (provavelmente) cmd / link / internal / riscv64 / asm.go . Embora eu não tenha certeza do que é realocação.

@carlosedp ainda existe a ligação do trabalho relacionado necessário antes que o cgo seja possível - elfreloc1 atualmente equivale a:

func elfreloc1(ctxt *ld.Link, r *sym.Reloc, sectoff int64) bool {
        log.Printf("elfreloc1")
        return false
}

Mais boas notícias, o módulo x/sys foi atualizado: https://github.com/golang/sys/commit/4c3a928424d249a1013e789cf5e458d480bcba16

Estou muito feliz em ver todo o progresso sendo feito nesta porta!

Estou interessado em ajudar a colocar isso na árvore Go principal. Aqui está uma lista de coisas que acho que precisamos resolver para que isso aconteça. As pessoas acham que poderíamos fazer isso por 1,14?

  1. Construtores. Este é o problema nº 30262. Acho que essa pode ser a parte de infraestrutura mais importante de que precisamos. Os detalhes estão nessa questão, mas Brad acha que a melhor maneira de avançar é apenas fazer o QEMU dos construtores no x86, construindo nativamente e testando com o QEMU. Eu adoraria ver o dia em que possamos colocar as máquinas nativas riscv na nuvem, mas o ecossistema ainda não está lá.
  2. Sincronizando com a ponta. Se quisermos entrar para 1.14, provavelmente devemos ter algo sincronizado e pronto para funcionar quando o congelamento expirar.
  3. Revisões de código. Envie-os! Fico feliz em colocá-los em campo ou delegá-los.
  4. Mantenedores. Alguém quer ser voluntário?

Esta lista é basicamente a minha destilação da política de portabilidade .

Avise-me se precisar de algo do meu lado.

Alguém viu alguma tração no bug QEMU CAS ? Isso ainda é um problema?

Olá @ randall77 , vou começar a pesquisar https://github.com/golang/build/tree/master/env/linux-arm-qemu para criar um construtor para Risc-V.

Em relação ao bug do Qemu, @ 4a6f656c enviou um patch que corrige o teste do bug com os programas de replicação vinculados a ele. Vou tentar construir e testar o Go em um Qemu que construí com este patch para testar.

Eu configurei um rastreador para os envios e dependências de RP aqui: https://github.com/carlosedp/riscv-bringup

https://go-review.googlesource.com/c/build/+/177918 foi minha tentativa recente de configurar construtores baseados em QEMU. Não está completo, no entanto. Ele ainda faz muito no convidado virtualizado (== ele usa muita CPU e é muito lento). Eu preciso enviar os arquivos para o host (x86) em vez do convidado (arco emulado) e usar o compartilhamento de arquivo 9p do qemu ou algo para compartilhar o $ WORKDIR entre o host e o palpite. Vou trabalhar nisso mais tarde.

Olá @ 4a6f656c , Eu construí com sucesso o Go on Qemu com o patch atomics que você enviou, mas preciso usar GOGC = off, caso contrário, recebo este erro:

No Unleashed, ele testa 100%.

Estou interessado em ajudar a colocar isso na árvore Go principal. Aqui está uma lista de coisas que acho que precisamos resolver para que isso aconteça. As pessoas acham que poderíamos fazer isso por 1,14?

facilmente.

  1. Construtores. Este é o problema nº 30262. Acho que essa pode ser a parte de infraestrutura mais importante de que precisamos. Os detalhes estão nessa questão, mas Brad acha que a melhor maneira de avançar é apenas fazer o QEMU dos construtores no x86, construindo nativamente e testando com o QEMU. Eu adoraria ver o dia em que possamos colocar as máquinas nativas riscv na nuvem, mas o ecossistema ainda não está lá.

O QEMU é o caminho a percorrer se conseguirmos tração do pessoal do QEMU, o que parece não estar acontecendo.

Alguém conhece uma pessoa do QEMU disposta a correr com isso? http://lists.nongnu.org/archive/html/qemu-riscv/2019-05/msg00134.html

  1. Sincronizando com a ponta. Se quisermos entrar para 1.14, provavelmente devemos ter algo sincronizado e pronto para funcionar quando o congelamento expirar.

@ 4a6f656c também tem um branch de ponta.

  1. Revisões de código. Envie-os! Fico feliz em colocá-los em campo ou delegá-los.

Eu me ofereço.

  1. Mantenedores. Alguém quer ser voluntário?

Você enviou o patch para qemu-devel? Todos os patches enviados devem ser
enviado para esta lista. qemu-riscv é uma lista opcional para qemu específico de RISC-V
discussões, mas não é um substituto para qemu-devel. Não há problema em enviar um
patch para qemu-devel e cc qemu-riscv. Muitas pessoas estão fazendo isso.

Infelizmente, não temos um desenvolvedor de qemu RISC-V dedicado no
momento. Alistair Francis da WDC se preocupa com RISC-V e é um qemu
mantenedor que pode aprovar patches. Se ele vir seu patch, ele provavelmente irá
reveja o patch. Ele só lê qemu-devel, mas você precisa enviar o patch
lá de qualquer maneira se você ainda não o fez. Se ele não responder depois de uma semana
ou dois, você pode tentar enviar um ping para uma revisão.

Palmer Dabbelt é o mantenedor padrão do RISC-V qemu, e fará o commit
o patch se Alistair Francis aprovar. Palmer é o padrão
mantenedor de algumas dezenas de pacotes, então pode demorar um pouco antes que ele
tem tempo para o seu patch, e se for um patch não trivial, pode acabar
na fila atrás de outros patches.

Jim

Ei, eu estava de férias na última semana e meia, então não tenho assistido.

Eu não vi o patch na lista QEMU (como Jim mencionou se precisa ser enviado para qemu-devel). Joel encaminhou o patch para mim, entretanto, eu adicionei alguns comentários. No geral, acho que o patch parece bom e podemos mesclá-lo :)

Apenas para referência futura, é sempre melhor enviar todos os patches aos mantenedores do qemu-devel e CC (retornados pelo script get_maintainters). Assim não se perderá.

O diff foi enviado para qemu-riscv @ e eu tinha a intenção de CC qemu-devel @, embora aparentemente isso não tenha realmente acontecido. FWIW, enviei uma versão revisada da diferença para ambas as listas na semana passada:

https://lists.nongnu.org/archive/html/qemu-devel/2019-06/msg03381.html

https://lists.nongnu.org/archive/html/qemu-riscv/2019-06/msg00053.html

Olá a todos, como podemos coordenar o envio do patch para considerar a próxima janela de mesclagem (1.14)?

@bradfitz você precisa de ajuda na configuração do construtor?

Também posso me oferecer como voluntário, mantendo meu conhecimento sobre Go innings :)

/ cc @ianlancetaylor @ randall77 e @rsc talvez já que Brad está de licença.

A primeira etapa, de acordo com https://golang.org/wiki/PortingPolicy , é colocar um construtor em execução.

Em seguida, deve ser possível separar os patches em alterações que afetam os arquivos existentes e alterações que adicionam novos arquivos. As alterações que afetam os arquivos existentes devem ser enviadas primeiro. Todas as mudanças substanciais devem ser agrupadas por diretório de nível superior (por exemplo, runtime , cmd/compile , etc.). Pequenas alterações, como adicionar riscv64 tags de construção, podem ser enviadas como uma única alteração. Vamos tentar obter a maior parte dessas alterações compartilhadas primeiro, junto com os novos arquivos necessários para manter tudo em construção.

Em seguida, os outros novos arquivos podem ser adicionados à vontade.

Eu realmente não acho que muita coordenação será necessária. Acho que o difícil serão as revisões.

Eu adicionei ao fork do construtor golang aqui https://github.com/carlosedp/build/tree/riscv64 o cross-builder para riscv64.

Eu construí com sucesso a bifurcação no contêiner do Docker gerado (executando make docker em env/linux-riscv64-cross . Depois disso, eu transferi o Go construído para a placa Unleashed e construí alguns projetos com ele.

Isso é baseado em @bradfitz CL https://go-review.googlesource.com/c/build/+/177918.

A mudança https://golang.org/cl/187637 menciona este problema: add riscv64 to endian_little

Mudança https://golang.org/cl/188501 menciona este problema: all: add riscv64 cross builder

Mudança https://golang.org/cl/188777 menciona este problema: text: bump x/tools

Joel, você precisa de ajuda para criar e enviar os patches destinados ao Go 1.14?

@ necrose99 infelizmente, o K210 não tem uma implementação mmu funcional e com apenas 8 MB não é possível rodar Linux nele. Existem projetos para expandir a RAM e vi um vídeo como um poc, mas não é viável agora.

Eu deixei a bola cair nisso. O ramo riscv de Joel está sendo fundido no golang?

Acredito que o congelamento de 1,14 começa em novembro, então chegamos a tempo. Vocês acham que dá muito trabalho começar a enviar os CLs para serem revisados? Eles precisam ser divididos de alguma forma? Pensamentos @ 4a6f656c ?

A primeira etapa é um construtor. Existe um construtor em execução?

Olá @ianlancetaylor , enviei um CL com base no trabalho @bradfitz aqui: https://golang.org/cl/188501

@ianlancetaylor presumindo que o construtor está funcionando, o que mais você precisa que façamos?

O ramal riscv do IIRC foi atualizado para funcionar com o 1.13 e vou verificar isso.

@ 4a6f656c, você conhece algum problema pendente?

Assim que o construtor estiver funcionando, pode começar a enviar patches conforme mencionado acima (https://github.com/golang/go/issues/27532#issuecomment-509360354). Obrigado.

Os últimos commits na árvore @ 4a6f656c funcionam e testam 100% conforme postei alguns dias atrás. @ianlancetaylor alguma chance de obter uma revisão do CL do construtor que enviei?

Eu executei ping no builder CL. Eu não trabalhei nos construtores.

Se estiver construindo para a arquitetura arm64, por exemplo, ele será concluído sem erros (usando o mesmo Go).

Alguma ideia @tklauser @bradfitz @josharian ?

Talvez um pouco mais interessante (e barulhento), eu construí o branch riscvdev-wip de @ 4a6f656c e obtive este rastreamento de pilha:

Da mesma forma, executar o mesmo teste apenas substituindo o arco por ARM64 não gera esse erro.

Feliz Natal a todos.

Houve uma dúvida, relacionada à escolha do hardware / placas. Eu tenho duas placas de hardware, para testar em: https://open-isa.org e longan.sipeed.com/en/. Longan nano é realmente chique - então, eventualmente, eu consegui dois microprocessadores na minha placa Vega e um no Longan nano (32 bits).

Deixe-me saber se alguém deseja usar o backend do GCC, para risc-v, nessas placas. O backend do compilador Btw RISC-V é amplamente contribuído para a causa do porte do FreeBSD - então assuma que, trabalhe no front-end do compilador, para GCC.

Esta não é uma discussão relacionada ao Clang / LLVM - mas as coisas relacionadas ao LLVM excluem a libffi. Além disso, quaisquer aplicativos embutidos e IoT excluem a própria libffi, uma vez que não há razão para realizar chamadas de código empacotado (Golang -> chamadas C) - isso não é razoável para modos de execução ciente do sistema operacional (firmware) e dentro do kernel (espaço de usuário para IoT também possui limitações de segurança típicas). Isso é válido para todas as distros Linux.

Eu estava curioso sobre o plano, para apoiar https://github.com/riscv/riscv-fast-interrupt/blob/master/clic.adoc .

Eu tinha acabado de notar o mesmo problema e preenchi o número 36871 para rastreá-lo.

Ok, atualizarei o TODO em CL 216841 para apontar para esse problema mais específico.

Vamos manter esse problema de rastreamento geral aberto até que # 36871 seja resolvido, para evitar que pareça que o trabalho de adicionar uma porta RISC-V esteja concluído.

@dmitshur - Não vejo nenhuma referência a trybots no documento PortingPolicy, você quer dizer builder? Em caso afirmativo, existe um construtor para este executado por @bradfitz , embora atualmente pareça estar ausente. Também posso executar um construtor assim que o problema mencionado em https://github.com/golang/go/issues/25498#issuecomment -570783627 for resolvido.

Seria possível fazer upload de binários rc1 para a página de download?

@davidlt , RISC-V ainda é considerada uma porta experimental no Go 1.14, portanto não forneceremos downloads.

@davidlt É muito fácil inicializar o golang de outra arquitetura (por exemplo, amd64), consulte por exemplo:
https://github.com/carlosedp/riscv-bringup/blob/master/build-golang.md

Também criei Go 1.14rc1 para riscv64 e disponibilizei o tarball em https://github.com/carlosedp/riscv-bringup/releases.

@dmitshur - há algo impedindo que esse problema seja fechado?

suporte cgo :)

o suporte cgo para riscv é rastreado em # 36641

Mudança https://golang.org/cl/240377 menciona este problema: doc: add riscv64 to ports list

Alguém deseja oferecer suporte a RISC-V para https://go.googlesource.com/gollvm/ ?

A alteração https://golang.org/cl/250997 menciona este problema: doc: add linux/riscv64 valid combination

O suporte experimental foi adicionado no Go 1.14 e no Go 1.15 para melhorar a estabilidade e o desempenho . O suporte para cgo em linux / riscv64 é rastreado em # 36641.

Portanto, estou considerando o suporte básico para RISC-V a ser feito e estou encerrando este problema. Vamos abrir questões específicas separadas para qualquer desenvolvimento posterior (por exemplo, suporte a gollvm) e melhorias.

Obrigado a todos por contribuir!
