First problem I ran into is that it uses the upper-case march format. Fixed that like this:

Then I got the following build error:

I think the pk build line should export CC=riscv64-unknown-elf-gcc before invoking the build.

It got removed in commit 2991201

This option is necessary as the user might want to build the other projects with a custom gcc.

While installing the tool chain we are getting the errors like

We are a company focus on some mixed-signal sensor product, we are very exciting about RISC-V and plan to customize design an in-house ultra low power RISCV core with some special custom instructions. In this deep embedded IoT application, RV32EMC is the best ISA choice. However when we build the riscv-tools, the error reported that the RV32EMC is not supported now. This is very depressing to us. We believe RISCV is going to be brilliantly in deep embedded IoT domain, hence RV32EMC is very important. So sincerely may I have a question when RV32EMC will be supported in riscv-tool?

I've just installed riscv-tools on ubuntu 15.04. In addition to the packages mentioned in README.md, I've also had to apt-get install libtool. Maybe you want to add it to the list in README.md.

Is there a way to tie the installed version of tools with their version on github? If at some time in the past I installed the tools with ./build.sh, can I determine what git commit I used to build them?

If it does exist, it would be a good command for someone to run if they are having problems and we suspect they are using an old version of the tools.

Hi,

The guide in README.md currently uses make -j (without a number) in three places. If make is actually called that way, it will spawn as many concurrent processes as the makefile allows, effectively acting as a fork bomb on larger projects. To avoid this, I'd recommend using a default number of jobs in the examples, e.g. make -j 16.

I wrote a test program in C consisting of an empty main method. When running it with spike and pk, the PC jumps to address fffffffffffffffe and segfaults. After running spike with a commitlog, I've discovered that the problem lies somewhere in the procedure linkage table in the test executable.

I followed the instructions in risc-v repositories in order to have linux running over Spike.
When trying to boot linux with the following command:
spike +disk=path/to/linux-4.6.2/root.bin path/to/riscv-pk/build/bbl vmlinux
I get "Kernel panic". First interesting error in the output is:
VFS: Cannot open root device "(null)" or unknown-block(0,0): error -6

After some research I found some posts which claim that the block device is not supported anymore and I shouldn't use the +disk argument. Instead I should use initramfs. E.g.:
http://stackoverflow.com/questions/37849574/how-to-rebuild-bbl-with-payload-option

I would be greatful to have instructions of how to use initramfs in order to make linux running over Spike (I'm not a linux-kernel expert).
Also I suggest to update the README.

Thanks

I'm pretty sure this is because spike isn't in the PATH when the test is executed. There are 2 possible solutions I can think of:

1. Update PATH before executing the test.
2. Set the RISCV_SIM environment variable with the full path to the installed spike.

Since I have no way of testing changes, I don't think I can productively help more than make this suggestion.

I haven't triaged it yet. To be honest, I'm not even sure if we default to glibc or newlib here. This is the current riscv-tools as of this moment.

Hi, I download the riscv-tools, install the tool with --with-xlen=32 option, I can successfully run hello world with [https://github.com//issues/41](issue 41), then I try to compile C code with the specific RV32I ISA, I tried two ways:

1, I try to use compile option -march=RV32I to compile the C code, and then use command: spike --isa=RV32I /path/to/32bit/pk/pk hello. There is no output, but if I change the command to spike --isa=RV32, the output is as expected.
2, I try to install the tool-chain with option --with-arch=I --with-xlen=32, the result is as 1.

Is there anything wrong? How can I only use RV32I isa?

I get this error when i try to run build script:

Right now the priv-1.9 branch includes some changes from future privileged specs (priv 1.9.1 according to commits), and some of those changes aren't compatible with priv-1.9 (for example: misa's CSR number changed). Is it possible to keep the priv-1.9 branch as just priv-1.9 and move the priv-1.9.1 work to a separate branch? Tags or releases would work as well for priv-1.9.

Hi,

I was trying to integrate the spike test suite into the riscv-tools .travis.yml, but I noticed that gdb wasn't installed (build log). I also noticed that the riscv-gnu-toolchain Makefile.in uses --disable-gdb in a few places. What's the status of testing gdb in travis?

I haven't triage this yet, but want to bring attention to it. With a clean pull of

Hi

To help people get going with RISC-V I have containerized most of the stuff in the riscv-tools repo. The container image can be pulled from https://hub.docker.com/r/sbates130272/riscv/ and the underlying dockerfile can be found at https://github.com/sbates130272/docker-riscv.

It would be great to have people do a bit of testing on this before emailing the wider audience via the mailing list. The plan would be to update this container when new "releases" of the riscv-tools repo is done.

Note there are currently a couple of issues. One is that "mount" is not allowed in a Docker contain and the other is you need AUFS support as the image size exceeds 10G. I'd be happy to review PRs against the Dockerfile is people have better options for these issues or want to add more things to the image.

Normal following-the-directions style build - define RISCV, export RISCV in path and as variable, install all Ubuntu Linux dependencies, run build.sh, produces the following:

make[3]: *** No rule to make target '../build-x86_64-unknown-linux-gnu/libcpp/libcpp.a', needed by 'build/genmatch'. Stop.
make[2]: *** [all-gcc] Error 2
make[1]: *** [all] Error 2
make: *** [stamps/build-gcc-newlib] Error 2

Full gory details of output below.
But it seems either the build is expecting libcpp.a was already built or something is wrong in the makefile.

My experience suggests that probably this is a case of an expected environment variable that doesn't exist on my system. Or an expected script that wasn't run.

I hope it isn't a situation where the build is designed so that you mustn't set the RISCV directory to the same path as the location of the build.sh file (i.e. you must build into an entirely different directory from the source)

The links for both linux-build.sh and busybox-riscv.config are both currently broken after the changes to the website. They're both linked under http://riscv.org/install-guides/ at the moment, which is no longer accessible.

During my riscv evaluation I found that I miss some well known projects I am sure will be needed by others too.

1. Buildroot
2. uClibc
3. u-boot

Is there a plan to add them to https://github.com/riscv/ ?
And later to maintain and upstream the riscv port?

Thanks
Noam

I've successfully built master on Linux however I am having trouble building master on macOS X.

Here is my stamps dir:

ls stamps/
build-binutils-newlib

It's failing on the second step: build-gcc-newlib

I noticed that the subdirectory exists. It's almost as if one of the copy commands is working differently on macOS X has there is an additional subdirectory newlib-gcc/newlib containing the source instead of newlib-gcc which is what the Makefile is expecting.

mclark@monty:/Volumes/riscv-toolchain-build-master/riscv-tools/riscv-gnu-toolchain/build$ ls /Volumes/riscv-toolchain-build-master/riscv-tools/riscv-gnu-toolchain/build/src/newlib-gcc/newlib/configure

Any ideas on how to troubleshoot?

I really only need binutils for the latest CSRs so I could perhaps overlay the binutils on top of an older gcc...

I'm trying to simulate multicore RISC-V processor on Spike using a "-p2" flag.
While debugging I do see that two processor_t objects are created.

However according to the following indications it seems that only single core is actually used:

1. I'm running simple vmlinux with Busybox according to the instructions in the README, and having the following cpuinfo content:

    / # cat /proc/cpuinfo 
    hart	: 0
    isa	: RV64G
   

2. When trying to execute the program below, I see by debugging Spike that all the program's instructions are executed on same processor.

3. EDIT: Another indication: Following code prints 1:

    #include <stdio.h>
    #include <unistd.h>
   
    int main (void)
    {
        int numCPU = sysconf(_SC_NPROCESSORS_ONLN);
        printf ("cpu count: %d\n", numCPU);
        return 0;
    }
   

Maybe Busybox doesn't utilize by default the two processor? Something else?
As first stage, also executing multithreading on the embedded simulator (without linux) is also applicable. I just don't know how to do that - pthread API is not available on the non-linux compiler and I wonder which threading API does.

The program mentioned above:

    #define _GNU_SOURCE

    #include<stdio.h>
    #include<string.h>
    #include<pthread.h>
    #include<stdlib.h>
    #include<unistd.h>

    int threads_count;
    cpu_set_t *cpuset;
    pthread_t *tid;

    int counter;
    pthread_mutex_t lock;

    void* doSomeThing(void *arg)
    {
        unsigned long i = 0;
        long index = (long)arg;

        int err = pthread_setaffinity_np(tid[index], 1, cpuset + index);
        //int err = pthread_setaffinity_np(pthread_self(), 1, cpuset + index);
        if (err != 0)
          printf("\ncan't INTERNALLY set affinity of thread %d: [%s]", index, strerror(err));

        printf("\n Job %d started\n", counter);

        for(i=0; i<10;i++)
        {
            pthread_mutex_lock(&lock);
    	counter++;
    	pthread_mutex_unlock(&lock);
        }

        printf("\n Job %d finished\n", counter);

        return NULL;
    }

    int main(char **argv, int argc)
    {
        int i = 0;
        int err;
        counter = 0;
        
        threads_count = 6;
        cpuset = (cpu_set_t *)malloc(sizeof(cpu_set_t) * threads_count);
        
        if (pthread_mutex_init(&lock, NULL) != 0)
        {
            printf("\n mutex init failed\n");
            return 1;
        }


        for (i = 0; i < threads_count; ++i)
        {
            CPU_ZERO(cpuset + i);
            CPU_SET(i, cpuset + i);
        }

        tid = (pthread_t *)malloc(sizeof(pthread_t) * threads_count);

        for (i = 0; i < threads_count; ++i)
        {
            long l = i;
            err = pthread_create(tid + i, NULL, &doSomeThing, (void *)l);
            if (err != 0)
                printf("\ncan't create thread :[%s]", strerror(err));

    	err = pthread_setaffinity_np(tid[i], 1, cpuset + i);
        if (err != 0)
    	    printf("\ncan't set affinity of thread %d: [%s]", i, strerror(err));
        }

        pthread_join(tid[0], NULL);
        pthread_join(tid[1], NULL);
        pthread_mutex_destroy(&lock);

        free(tid);
        free(cpuset);

        return 0;
    }

I am trying to create riscv64 toolchain using buildroot.
I used sifive-next branch as a base to my work.
I used binutils-2.28, gcc-7, glibc-riscv-next, Linux-riscv-next (for Linux headers).

I managed to create working toolchain for riscv64 with this commit
However I found 3 issues I worked around and needed to get fixed.

1. GCC fails to build GLIBC without warning (I add to --disable-werror to configure)
   I think that GCC fails to see that size of -1L is same as a pointer.
   log is:
   ../sysdeps/unix/sysv/linux/mmap64.c: In function ‘__mmap64’:
   ../sysdeps/unix/sysv/linux/mmap64.c:45:12: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
   return (void *) INLINE_SYSCALL_ERROR_RETURN_VALUE (EINVAL);

2. Faild to build stage 1 compiler (aka inital gcc) due to misssing file
   log is:
   make[3]: *** No rule to make target '../../gcc/testsuite/selftests', needed by 's-selftest'. Stop.
   make[3]: *** Waiting for unfinished jobs....

3. missing kernel file needed by linux headers, add an empty one arch/riscv/include/uapi/asm/setup.h
   log is:
   scripts/Makefile.headersinst:72: *** Some mandatory headers (setup.h) are missing in arch/riscv/include/uapi/asm. Stop.
   scripts/Makefile.headersinst:26: recipe for target 'asm' failed

Note:
Still with this kernel spike is not booting, need to go back to master (4.6.y)

hello,everyone.

I read a report for RVC(https://people.eecs.berkeley.edu/~krste/papers/waterman-ms.pdf ), then I'd like to use the RVC to do the similar tests. But it is ambiguous for me to how to do those experiments. I get several problems:

1. the gcc could not generate the RVC code or assemble code automatically. even with the option -march. I don't know if I did something wrong, because there is no guide book.

2. I could get the RV assemble code, then I add the RVC assemble code to replace the RV assemble code. the assemble file can generate the elf file, but when I got the instruction list with "spike -l pk", it always tells me there are errors:
   -exception illegal instruction, it is a div instruction.
   -exception trap instruction access fault
   firstly I just thought it was my fault because I modified the assemble file manually. But when I try the RV code, it returns the same error.The compiling and simulating options as follow:
   - riscv64-unknown-elf-gcc -march=RV64IFDC
   - spike --isa=RV64IFDC -l pk

3. In my virtual machine, it is strange about the supporting instruction sets.
   - Compile the code without the F/D sets, there is a assembler message error " Architecture doesn't allow hardfloat ABI"
   -Compile the code with M set, there is another assembler message error " Unsupported ISA subset M"
   - the RV64IFDC could get through the compile but do not get the correct executable file.
   I really get lost……

4. when I dump the executable file with riscv64-unknown-elf-objdump -d, I could not find the RVC instrucions I added. I guess they are all decoded into RV instructions. Is that ture?

5. Are there some options or command lines to tell the gcc to get the RVC assemble file automatically instead of modifying the normal RV assemble file manually? from the report I give above, it mentioned a RVC assembler, but I reeeeeeeeealy do not know how it work and, where the assembler is.

If I did something wrong, please tell me and help me to correct them.
So many thanks to any reply.

Hello,

RDINSTRET allows us to know the number of instruction retired by processor and by thread i thing.
is it a way to know the number of retired instruction by each execution unit ?
for example : BOOM core 3 issues has 6 execution units, i would like to know the number of instruction retired by each execution units (ALU, FP ...) for each thread.

Thank you in advance

HI Support ,

Could you please help us to install riscV from scratch , I am using Centos 6

Note: This solution is a backdoor approach since it modifies .git/config directly. There should be a better method.

Hello team,
I build the riscv-tools from branch bump-gcc in order to build rv32ima variant that i'm working on. Then I tried to build the riscv-tests from instructions, but a error raised during make:

mm.o: na função.L5':
mm.c:(.text+0x12c): referência indefinida para fma' mm.c:(.text+0x154): referência indefinida para fma'

I imagine that some configuration on configure.ac could work, since it is related to a missing reference for fma function present on math.h included on the mm.c that generate the error. But this is far from my knowlodge on GNU build tools.

Hi all,

I am able to compile & run riscv-tools in 64b mode but I am having some trouble with getting 32b applications running. I seem to be able to compile riscv-tools for 32b mode but riscv-tests failed to compilete, see my comment on #39 for more informations.

When I try to run the helloworld application as documented in the README file I get the expected behavior in my 64b environment, but it fails in my 32b environment, see below.

What I have:

• 32b installation of HoB riscv-tools in /tools/riscv-tools/install/riscv-tools.20160908-master-32b
• 64b installation of HoB riscv-tools in /tools/riscv-tools/install/riscv-tools.20160908-master-64b

64b env:

VER=20160908-master-64b

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/tools/riscv-tools/install/riscv-tools.$VER/lib64/:/tools/riscv-tools/install/riscv-tools.$VER/lib/

warning: only got 2931818496 bytes of target mem (wanted 4294967296)

what(): could not open pk

When I point it to the 32b version of pk I no longer get the "could not open" error above but I just get this (no Hello World!):

spike /tools/riscv-tools/install/riscv-tools.20160908-master-32b/riscv32-unknown-elf/bin/pk hello32
warning: only got 2931818496 bytes of target mem (wanted 4294967296)

Anyone any idea of what could be wrong?

Thanks,

Michael

More of a question than an issue, is -msoft-float [supposed to be] supported? I get an internal gcc error if I try to use it. I'm sorry if I missed documentation to this effect.

Hi

On my system I noticed that to generate the init file correctly as a symbolic link I needed to be in the init folder and then issue the command 'ln -s ../bin/busybox init' rather than the command in the README. Might be worth altering the README to make that step a bit clearer?

Stephen

Hello,

Can you please help ?

./build.sh
riscv toolchain build success

riscv64-unknown-elf-gcc hello.c
spike pk a.out
terminate called after throwing an instance of 'trap_store_access_fault'

It would be nice if it was possible to pass these options to the configure scripts since allow it to use a local installation of newer versions of gmp,mpc and mpfr without root rights.

Building the commit checked into rocket-chip 83a3143 with build.sh works fine until you run the isa tests.

$ cd riscv-tests/isa
$ make run
...
  [ FAILED ] rv64mi-p-breakpoint.out     (tohost = 5)
  [ FAILED ] rv32mi-p-breakpoint.out32   (tohost = 5)

This corresponds to the test commented "Make sure writes don't trap"

In the riscv-llvm submodule's current tag has a riscv-clang submodule that still uses ssh. Looks like it has been updated in risc-llvm master, just needs to be bumped up to a newer change.

Build fails with

Configuring project riscv-gcc
Building project riscv-gcc
/bin/sh: 2: CFLAGS+=-Wno-error=deprecated-declarations: not found

This seems to be an invalid syntax when being processed by the default ubuntu dash shell (which is what gets executed by /bin/sh) in riscv-gcc/Makefile.in.

Changing line 30 of Makefile.in to

SHELL := /bin/bash

Gets the toolchain building (though with lots and lots of warnings - perhaps expected) and a simple spike pk helloworld test worked.

so,how to deal with it? thank you sooooo much!

I build the complete toolchain before. Last year in December.

I followed the exact same steps, but this time ran into a build error when executing:
$ ./build.sh

`/home/usr/RISCVTools/riscv-tools/riscv-gnu-toolchain/build/src/newlib-gcc/gcc/lto-compress.c:34:18: fatal error: zlib.h: No such file or directory
#include <zlib.h>

compilation terminated.

make[3]: *** [lto-compress.o] Error 1

make[2]: *** [all-gcc] Error 2

make[1]: *** [all] Error 2

make: *** [stamps/build-gcc-newlib] Error 2
`

I searched in the folder for the missing header zlib.h and it's nowhere to find.
Did i miss something?

Ubuntu 16.04
GCC 5.4 and 4.8 (both tried)

I am on Mac OS X El Capitan building riscv-tools. With Clang version:
Apple LLVM version 7.0.2 (clang-700.1.81)

After long into the build with most of the riscv64-unknown-linux-gnu-* done I got an error in the posix build. It stopped at pread.c compilation as follows:

Anyone can help? I tried looking for past issues and cannot find this one. I am still new to github so please bear with me if I am wrong.

Thanks!

If you could please tell me what I'm missing or how to fix it, I would very much appreciate it.
Thank you !

Hi

Great notes here but I noticed that to compile the Linux kernel for RISCV you need the Linux bc tool and that is not installed by default on Ubuntu. So you might want to add it to your list of apt-get install in your READMEs on this repo and some of the submodule repos.

Thanks - Stephen

It's not clear how to build this on a Mac (it has worked in the past). Maybe we could
add a blurb to the README.

This is a tracking issue - I'll fix it.

I`m trying execute this command ( spike -l bbl vmlinux ), but i got a infinite loop.

Completely no idea on this error, can anyone provide a tip?
Thanks~

I am getting a compile error when building with ./build.sh.

I am on Ubuntu 16.04. I have tried gcc-4.8 and gcc-5.4.

I have installed the apt-gets in the README. I have also set RISCV and added $RISCV/bin to PATH.
