If I enable CONFIG_X86_X32 in kernel 3.4 and compile the ati-drivers 12.6_beta, modprobing fglrx fails with "unknown symbol old_rsp". This is due to ati-drivers-old_rsp.patch, which only adds the line DEFINE_PER_CPU(unsigned long, old_rsp); if CONFIG_X86_X32 is not defined. Removing the #ifndef CONFIG_X86_X32 and #endif lines above and below fixes the problem. Reproducible: Always Steps to Reproduce: 1. Compile kernel 3.4.0 with CONFIG_X86_X32 enabled 2. Emerge ati-drivers-12.6_beta 3. Modprobe fglrx Actual Results: fglrx fails to load with unknown symbol old_rsp in dmesg Expected Results: fglrx loads Portage 2.2.0_alpha110 (default/linux/amd64/10.0/desktop, gcc-4.7.0, glibc-2.15-r2, 3.4.1 x86_64) ================================================================= System uname: Linux-3.4.1-x86_64-Intel-R-_Core-TM-_i7-2630QM_CPU_@_2.00GHz-with-gentoo-2.1 Timestamp of tree: Tue, 05 Jun 2012 17:30:01 +0000 app-shells/bash: 4.2_p29 dev-java/java-config: 2.1.11-r3 dev-lang/python: 2.7.3-r2, 3.2.3-r1 dev-util/cmake: 2.8.8-r2 dev-util/pkgconfig: 0.26 sys-apps/baselayout: 2.1-r1 sys-apps/openrc: 0.10.2 sys-apps/sandbox: 2.5 sys-devel/autoconf: 2.13, 2.69 sys-devel/automake: 1.11.5, 1.12.1 sys-devel/binutils: 2.22-r1 sys-devel/gcc: 4.7.0 sys-devel/gcc-config: 1.7.2 sys-devel/libtool: 2.4.2 sys-devel/make: 3.82-r3 sys-kernel/linux-headers: 3.4 (virtual/os-headers) sys-libs/glibc: 2.15-r2 Repositories: gentoo local-overlay Installed sets: ACCEPT_KEYWORDS="amd64 ~amd64" ACCEPT_LICENSE="*" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=native -O2 -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/share/openvpn/easy-rsa" CONFIG_PROTECT_MASK="${EPREFIX}/etc/gconf /etc/ca-certificates.conf /etc/dconf /etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo /etc/texmf/language.dat.d /etc/texmf/language.def.d /etc/texmf/updmap.d /etc/texmf/web2c" CXXFLAGS="-march=native -O2 -pipe" DISTDIR="/usr/local/portage/distfiles" EMERGE_DEFAULT_OPTS="--jobs=6 --load-average=8.0 --binpkg-respect-use=y" FEATURES="assume-digests binpkg-logs config-protect-if-modified distlocks ebuild-locks fixlafiles news parallel-fetch parse-eapi-ebuild-head preserve-libs protect-owned sandbox sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch" FFLAGS="" GENTOO_MIRRORS="http://distfiles.gentoo.org" LANG="en_US.UTF-8" LDFLAGS="-Wl,-O1 -Wl,--hash-style=gnu -Wl,--sort-common -Wl,--as-needed" MAKEOPTS="-j8" PKGDIR="/usr/local/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --human-readable --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/local/portage/tree" PORTDIR_OVERLAY="/usr/local/portage/overlay" SYNC="rsync://qserv/gentoo-portage" USE="X a52 aac acl acpi alsa amd64 berkdb branding bzip2 cairo cdda cdr cjk cli consolekit cracklib cups cxx dbus dri dts dvd dvdr emboss encode exif firefox flac fortran gdbm gif gnome-keyring gpm gtk iconv imap ipv6 jpeg lcms libnotify mad mmx mng modules mp3 mp4 mpeg mudflap multilib ncurses nls nptl nsplugin ogg opengl openmp pam pango pcre pdf png policykit ppds pppd qt4 readline sdl session sse sse2 ssl startup-notification subversion svg symlink tcpd threads tiff truetype udev udisks unicode upower usb v4l2 vaapi vorbis x264 xcb xml xorg xulrunner xv xvid zlib" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache cgi cgid dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" CALLIGRA_FEATURES="kexi words flow plan sheets stage tables krita karbon braindump" CAMERAS="ptp2" COLLECTD_PLUGINS="df interface irq load memory rrdtool swap syslog" ELIBC="glibc" GPSD_PROTOCOLS="ashtech aivdm earthmate evermore fv18 garmin garmintxt gpsclock itrax mtk3301 nmea ntrip navcom oceanserver oldstyle oncore rtcm104v2 rtcm104v3 sirf superstar2 timing tsip tripmate tnt ubx" INPUT_DEVICES="evdev synaptics" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LIBREOFFICE_EXTENSIONS="presenter-console presenter-minimizer" PHP_TARGETS="php5-3" PYTHON_TARGETS="python3_2 python2_7" RUBY_TARGETS="ruby19" USERLAND="GNU" VIDEO_CARDS="intel fglrx" XTABLES_ADDONS="quota2 psd pknock lscan length2 ipv4options ipset ipp2p iface geoip fuzzy condition tee tarpit sysrq steal rawnat logmark ipmark dhcpmac delude chaos account" Unset: CPPFLAGS, CTARGET, INSTALL_MASK, LC_ALL, LINGUAS, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, USE_PYTHON
As far as I understand this is just becouse fglrx can't work with x32 applications for now. This should be fixed with the first release of ati-drivers supporting the 3.4 kernel series.
ati-drivers now fails early if CONFIG_X86_X32 is enabled.
It is possible that the 12.8 ebuild I just commited to gentoo (and some fixes to 12.6 after this bug was opened) will fix x32 support. Can anyone please test this?
