Disabling virglrenderer on only some host archs is a bit more complicated. I've opted to ignore the virglrenderer test failures on riscv64, reenabled virglrenderer in qemu, and uploaded virglrenderer/qemu/libvirt to focal-proposed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872931 Title: enable riscv build To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1872931/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1872931] Re: enable riscv build
qemu src has in ./linux-headers/linux/kvm.h #include #include #include So does /usr/include/linux/kvm.h on Focal BTW. There are two ways to resolve this: - via system includes by /usr/include/x86_64-linux-gnu/asm/kvm.h - via internal includes in qemu by ./linux-headers/asm-s390/kvm.h The latter does not exist for riscv and also it is a "<>" include so it should use the systems headers anyway right? $ dpkg -S /usr/include/x86_64-linux-gnu/asm/kvm.h linux-libc-dev:amd64: /usr/include/x86_64-linux-gnu/asm/kvm.h In the build log I see Get:8 http://ftpmaster.internal/ubuntu focal-proposed/main riscv64 linux-libc-dev riscv64 5.4.0-24.28 [1037 kB] That is from https://launchpad.net/ubuntu/focal/riscv64/linux-libc-dev/5.4.0-24.28 But that seems to not contain the kvm.h header: wget http://launchpadlibrarian.net/474114728/linux-libc-dev_5.4.0-24.28_riscv64.deb dpkg -x linux-libc-dev_5.4.0-24.28_riscv64.deb linux-libc-dev-riscv cd linux-libc-dev-riscv find . -name 'kvm.h' ... not existing in there ... This is blocked on getting a kernels riscv kvm.h into place.

[Bug 1872931] Re: enable riscv build
[11:23] wgrant: does enabling rsicv have a general FFe? [11:23] or do we need such processing for every change (I'd hope not) [11:54] It hasn't been suggested to me that an FFe was required for changes that were limited to riscv64. [11:55] I thought enabling another arch usually would fall under that category [11:55] wgrant: what is the immediate use case for this in 20.04 - will people really use it as a host? [11:56] cpaelzer: qemu-utils [11:57] qemu-img, etc. [11:57] And unblocking libvirt and its rdeps [11:57] libvirt is the fifth most common missing build dependency at present [11:57] xnox: to get a third opinion - do you happen to know if we'd need an FFe (or wait for 20.10) with that? [12:06] cpaelzer: hwe exception. We have standing exception for hardware enablement. [12:06] xnox: I know that for SRUs, are you saying this applies to FFe as well then? [12:07] cpaelzer: we need qemu-utils to build images. Ideally sooner than later. [12:07] well, ok under that banner I can work [12:07] thank you [12:07] cpaelzer: also applies to ffe. ** Changed in: qemu (Ubuntu) Status: New => In Progress ** Changed in: qemu (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872931 Title: enable riscv build To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1872931/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
