[arch-general] Trouble with QEMU GPU Passthrough via OVMF
by Maxence Sartiaux 27 Mar '17

27 Mar '17

Hello, I'm currently working to setup a windows virtual machine with gpu passthrough on my archlinux host. So at first i created a basic VM with a custom qemu command and it work great. qemu-system-x86_64 -enable-kvm -m 8192 -cpu host,kvm=off,hv_relaxed,hv_spinlocks=0x1fff,hv_vapic,hv_time,hv_vendor_id=whatever\ -smp cores=4,threads=2\ -device vfio-pci,host=02:00.0,x-vga=on\ -device vfio-pci,host=02:00.1\ -vga none\ -soundhw hda\ -drive file=/dev/sdb,id=diska,format=raw\ -drive file=/dev/sdd,id=diskb,format=raw\ -cdrom /dev/sr0\ -usb -usbdevice host:1b1c:1b13\ -usbdevice host:1b1c:1b12\ -usbdevice host:1b1c:1c08\ -usbdevice host:046d:0a1f\ -usbdevice host:28de:1142 Today i would to go use virt-manager to manage my virtual machine but if i create a basic virtual machine with only the gpu added the gpu is never used. I can see the GPU in the peripheral manager but it's in error 43. The -cpu argument have the same settings as my old setup ( -cpu host,kvm=off,hv_relaxed,hv_spinlocks=0x1fff,hv_vapic,hv_time,hv_vendor_id=whatever) Before on my old setup if i didn't add those options, the gpu was working i had an image on my screen. Here, the screen remain in sleep mode, i have to use a spice screen to see what's going on the vm. FYI, guest graphic card is a gtx670 02:00.0 & 02:00.1 [ 10de:1189 & 10de:0e0a ] So here's the qemu command line started by virtmanager /usr/sbin/qemu-system-x86_64 -name

[arch-general] [RFC] Make Archlinux websites mobile friendly
by Alif M. A. 27 Mar '17

27 Mar '17

I think it would be nice to have Arch websites mobile friendly, so that it can be viewed comfortably on any devices with different screen size. For starting point, let's make the wiki, which is the main source of information, mobile friendly. It's just a matter of adding meta viewport tag and another CSS file(s) for smaller screen sizes.

Also would be nice to have an official stance on whether full svn checkouts are okay, since https://www.archlinux.org/svn/ strongly warns people against doing so... and comparing all PKGBUILDs at once is somewhat awkward when using separate branches in git (though git-grep does take multiple trees at least). -- Eli Schwartz

May want to warn anyone running dovecot that sslv2 is no longer supported in openssl 1.1. And so if conf.d/10-ssl.conf has this line: ssl_protocols = !SSLv2 !SSLv3 this will lead to error and mail not working - change to: ssl_protocols = !SSLv3 -- Gene lists(a)sapience.com

[arch-general] What's the best way of packaging golang packages?
by Iru Cai 22 Mar '17

22 Mar '17

Hi, I'm not familiar with go, but I'm trying to use some go programs, caddy for example. I read the PKGBUILD of it. It first use `go get' to get the dependencies and then do the `go build'. However, I don't think it a good practice. I'm used to the way of installing the dependency packages first, then install the target package. Python packages are packaged this way. On the other hand, go packages has its features. Go programs are compiled to a single binary that do not link to other go libraries, so they doesn't depend on other go packages. I also read the Debian Go Packaging document ( https://pkg-go.alioth.debian.org/packaging.html) but I still don't know when and why we need to make a go package. I'm also confused when I see node.js packages. I see many of the packages are built using just an `npm install' so the packaging process will pull a lot of code, but I think it's better than that in go because the node.js packages are installed in the user home so that it won't be installed again when another node.js package needs the same dependency. Thanks, Iru -- Please do not send me Microsoft Office/Apple iWork documents. Send OpenDocument instead! http://fsf.org/campaigns/opendocument/

[arch-general] RFC: Cross compilers using newlib
by Christer Solskogen 21 Mar '17

21 Mar '17

Hi! Instead of having a separate binutils, gcc and newlib package for every architecture it is possible to combine them into one. You can even build them all in one swoop if you want. For instance, in something like this: _target=m68k-elf _binutilsver=2.28 _gccver=6.3.0 _islver=0.18 _newlibver=2.5.0.20170228 pkgname=${_target}-devkit pkgver=20170320 pkgrel=1 pkgdesc="A combined binutils/gcc/newlib kit for ${_target}" arch=('x86_64') options=('!strip') depends=('gmp' 'mpfr' 'libmpc') url="http://dummy.no" license=('GPL' 'LGPL' 'BSD') source=(binutils-${_binutilsver}.tar.gz gcc-${_gccver}.tar.gz isl-${_islver}.tar.gz newlib-${_newlibver}.tar.gz) md5sums=('d5d270fd0b698ed59ca5ade8e1b5059c' '6e5ea04789678f1250c1b30c4d9ec417' '076c69f81067f2f5b908c099f445a338' '6b7b45ed2280de9196df62511094fc58') prepare() { cd ${srcdir}/gcc-${_gccver} ln -s ../isl-${_islver} isl # Do not run fixincludes sed -i 's@\./fixinc\.sh@-c true@' gcc/Makefile.in # Create a combined source tree for i in bfd binutils gas ld opcodes do ln -s ${srcdir}/binutils-${_binutilsver}/$i done ln -s ${srcdir}/newlib-${_newlibver}/newlib mkdir ${srcdir}/build } build() { #binutils does not compile with the CPPFLAGS in makepkg.conf unset CPPFLAGS cd ${srcdir}/build ${srcdir}/gcc-${_gccver}/configure --prefix=/usr --libexecdir=/usr/lib --target=${_target} --enable-languages=c,c++ --disable-libstdcxx-pch --with-newlib make } package() { cd ${srcdir}/build make install-strip DESTDIR=${pkgdir} rm -rf ${pkgdir}/usr/share rm ${pkgdir}/usr/lib/libcc1* } Is this something that should be done?

[arch-general] pavucontrol depency question
by Friedrich Strohmaier 21 Mar '17

21 Mar '17

Hi all, some time ago xfce sorted out xfce4-mixer in favour of xfce4-pulseaudio-plugin. - agreed removing xfce4-mixer - Installed xfce4-pulseaudio-plugin - no sound mixing available at all - Installed optional dependency pavucontrol - no sound mixing available - no connection to pulseaudio server - Installed optional dependency pulsaudio - yay! sound mixing up an running. I don't understand much about dependency quirks but I wonder about the reason both dependencies beeing made optional. xfce4-pulsaudio-plugin is out of any functionality without working pavucontrol pavucontrol is out of any functionality without a running pulseaudio server. So what is the reason making both dependencies optional? -- Friedrich

[arch-general] URXVT background color
by arnaud gaboury 19 Mar '17

19 Mar '17

I run many urxvt windows on my screen. Some are for the host system and some are for my container (managed by systemd-nspawn). I am looking for a way to change color background according to hostname in order to quickly see which terminal I am on. My idea was to test $HOST variable in my ~/.xinitrc and give a specific .Xressource accordingly, but it doesn't work as .xinitrc is obviously not invoked when I fire a new terminal window. How can I manage what I am looking for (if I can)? Thank you for hints.
