Q: How to install some ebuild which are masked.
A: Dont use ACCEPT_KEYWORDS="x86" because it tends to break!
There are several methods to do this.
1) Just add "<package name> amd64" to your /etc/portage/package.keywords
2) You can use "ekeyword" from the gentoolkit-dev package:
| Code: |
ekeyword \amd64 /usr/portage/x11-libs/wxGTK/wxGTK-2.5.1-r1.ebuild
|
3) edit the ebuild manually like and add "amd64" in KEYWORDS variable, for example
| Code: |
nano /usr/portage/x11-libs/wxGTK/wxGTK-2.5.1-r1.ebuild
|
and then just "emerge wxGTK".
|
For me number 1) only works if instead of amd64 I use a keyword that is in the ebuild. For example, if there is only an x86 keyword in the ebuild, I then have to put '<package_name> x86'.
Also <package_name> is the full name including the category and unless you want to edit the package.keywords file alot you should pick a version and put '>=' at the beginning of the line. Similar to how dependecies are listed in the ebuild.
For example:
>=net-misc/icaclient-8.0-r2 -*
>=sci-mathematics/scipy-0.3 ~x86
>=dev-python/f2py-2.0 x86
The '-*' ignores all keywords.
This FAQ should really be included in the AMD64 Handbook. Thanks for the information. |

I fixed up some spelling/grammar/formatting. It was really bothering me, sorry 
Mostly u -> you, which is a pet-peeve of mine.
| Not what crazycat wrote: | This is a quick and dirty FAQ for gentoo on amd64. Feel free to add something and correct me.
VERY IMPORTANT
If you ask about something that does not work, please post relevant/related information, so we dont have to deduce it.
COMMON MISTAKES
Many people tend to forget to enable 32bit emulation in kernel, so CONFIG_IA32_EMULATION=y.
Please read gentoo on amd64 HANDBOOK .
Q: I am new and interested in amd64 improvements over old x86
A: Some little benchmarks can be found in this forum.
https://forums.gentoo.org/viewtopic.php?t=221045
and An interesting article 
Q: Will performance suffer if I use 32-bit emulation?
A: The 32-bit binaries will run as fast as you'd expect from a modern processor. The performance loss is insignificant.
Q: Example CFLAGS for amd64
A: gcc-3.4 : CFLAGS="-march=athlon64 -O2 -pipe"
gcc-3.3 : CFLAGS="-O2 -pipe"
Some agressive flags I have that worked ok for me "-frename-registers -fweb and -fomit-frame-pointer". GCC 3.4 produced code is quicker, but it is not compatible with everything now.
Q Example CFLAGS for em64t
A: Check this thread.
Q: Example CFLAGS for 32 bit installation on athlon64/opertron
A: Just like normal athlons, but you can use sse2.
https://forums.gentoo.org/viewtopic.php?t=177670&highlight=32+bit+cflags
Q: How to compile in 32 bits on amd64?
A: You have to compile gcc with "multilib" in your USE flags. Then take the software you want to compile and run
| Code: | | CFLAGS="-march=i386 -m32 -Xlinker=-m32" ./configure |
It works for me in 99% of cases, but wine won't compile this way, not everything  Check the question below about wine. Remember, You will also need 32 bit libs for your package installed. I tested this method so far on the freespace2 linux port, libaal, openal and it worked.
Q: How do I enable nx (non-execute) on amd64
A: This kernel boot parameters do the job : noexec=on and noexec32=on for 32 bit applications. Here are some amd64 boot parameters.
Q: How do I enable Cool and Quiet/Cool'n'Quiet/powernow
A: kernel config:
Power management options --->
[*] Power Management support
CPU Frequency scaling --->
[*] CPU Frequency scaling
<*> CPU frequency table helpers
<*> AMD Opteron/Athlon64 PowerNow!
You should also enable different governors here. I use "userspace" to change speed with
| Code: | | echo <speed in mHerz> > sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed |
For example:
| Code: | | echo 800000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed for 800mHz |
You can read the speed with
| Code: | | cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq |
You can also use /proc/sys/cpu/0/speed interface for that untill it gets deprecated. You can also use a special daemon (like cpudyn or powernowd or cpufreq) to manage speed automatically.
please correct me/add here because I dont use dynamical services and dont have a clue about them
Q: Bootloader on amd64
A: lilo , syslinux , grub:
| Code: |
emerge grub-static
cp /boot/grub/grub.conf.example /boot/grub/grub.conf
nano /boot/grub/grub.conf
|
The conf file is pretty self-explaining.
To install start "grub" and type "install (hd0)" to install it on mbr of the first (the one you boot from) drive or install (hd0,0) to install it for example on the first partition of this drive. You can also use "install (hd1)" to install it on the mbr of the second drive. It doesn't matter wether first boot drive is scsi/ide/sata, as long as you boot from it, it is hd0 for grub. The second thing you type here is to specify the partition where grub is installed. Example: "root (hd0,1)" for boot drive, second partition. Then grub should recognise the filesystem and you can boot using your /boot/grub/grub.conf.
Q: "Warning: many lost ticks. Your time source seems to be instable or some driver is hogging resources."
A: https://forums.gentoo.org/viewtopic.php?t=191716
Q: Lost Interrupts
A: https://forums.gentoo.org/viewtopic.php?p=1395349#1395349
Q: My 32 bit software needs * libraries.
A: 1) Check if you installed all emul- ebuilds with "emerge -s emul-linux-x86"
2) Use filename on google to get library name, get the 32 bit library from some other 32 bit distribution (I prefer fedora core 2). Convert the rpm to tar.gz by using rpm2targz. Copy unpacked libs in /usr/lib32, run ldconfig. Hope it works
Q: How to install some ebuild which are masked.
A: Dont use ACCEPT_KEYWORDS="x86" because it tends to break!
There are several methods to do this.
1) Just add "<package name> amd64" to your /etc/portage/package.keywords
2) You can use "ekeyword" from the gentoolkit-dev package:
| Code: | ekeyword \amd64 /usr/portage/x11-libs/wxGTK/wxGTK-2.5.1-r1.ebuild

3) edit the ebuild manually like and add "amd64" in KEYWORDS variable, for example
| Code: | nano /usr/portage/x11-libs/wxGTK/wxGTK-2.5.1-r1.ebuild
|
and then just "emerge wxGTK".
Q: Quake3-based games or (some other 32 bit 3d software) do not work and exit with this
| Code: |
..loading libGL.so.1: QGL_Init: dlopen libGL.so.1 failed: libnvidia-tls.so.1: cannot open shared object file: No such file or directory
|
A: Try exporting LD_LIBRARY_PATH="/usr/lib32/opengl/nvidia/lib/" and then running the game.
Works sometimes with other software which uses 3d, like cedega, somone reported it worked for qtopia.
It seems latest opengl-update also should fix the problem.
Q: AGP on amd64 ?
A: With nvidia you have to use in-kernel AGP, it is automatically enabled if you enable "IOMMU", else you could enable AGP in Device Drivers -> Character Devices -> /dev/agpgart. Then you have to set in your xorg.conf in section "Device"
Check with "cat /proc/driver/nvidia/agp/status"
Ati: no idea - dont have that ;P Suggestions will be greatly appresiated.
Q: Wine with amd64 ?
A: https://forums.gentoo.org/viewtopic.php?t=152597
Q: My flash / java / some other 32bit plugin doesn`t work.

and one thing for me.. pls change "800mHz" to "800MHz"
because 'm' stands for milli (wich would be 10^-3) and 'M' for Mega (the expected 10^6)  |

Because i was not that active in the forums lately. I also think it should be rewritten because many things have changed. Make some suggestions what to change and i will update it .
p.s. i changed the "yous" and added some stuff.
@slougi can u post exatly what to change. Also sorry, english is not my native language. I also would give you writing rights to the post but since i'm not a moderator i can't actually do so. |

Q. DRI OpenGL doesn't work with 32-bit applications (et, ut, whatever) on ATI, what can I do?
A.
| Code: | | export LIBGL_DRIVERS_PATH="/usr/lib32/modules/dri/:/usr/lib64/modules/dri" |
if your 3d application works then add
| Code: | | LIBGL_DRIVERS_PATH="/usr/lib32/modules/dri/:/usr/lib64/modules/dri" |
somewhere in your environment I suggest /etc/env.d/99local

I cant help you with lm_sensors caus i use just plain /sys/bus/i2c/devices/0-0290/temp2_input device node. If its too hot the computer shuts down. I also have it87 with gigabyte k8t800 board and it works, all but fans which work only with windows program. I also havent tried 2.6.12rc series. Does your it87 moule loads? check dmesg , if it does, you might try my solution

p.s. dnotify stuff didnt work so i commented it out. It was a C exercise for me and i run this program ever since. You might try to change the node path. I compiled it with "gcc mon.c" |

On wireless cards:
acx1xx (D-Link DWL-520+, DWL-G520+, other cards and companies too) seems to work fine, so long as you use a 2.6.10 or earlier kernel.
Other than that, a note on WMVs (win32 codecs) would be nice. |

A couple of questions:
1. For an amd64 fresh Gentoo stage3 installation, on a Venice core processor (i.e. with sse3 support) what do I need to add to the default CFLAGS in make.conf?
Is -msse3 enough?
2. Apart from that, for a dual-core Athlon-64-X2 CPU (it has sse3 support), what further actions should I take?
a. In make.conf USE flags threads nptl smp
b. In gentoo-sources 2.6.x kernel config, selecting an SMP configuration would it be enough?
Please feel free to correct and supplement me on the above.
Thank you. |

| I think i'd do exactly like you describe it. I'd configure it like an smp system without NUMA. I'm not sure if -msse3 is filtered out but I'd surery tried it out. |

Would there be any performance gain if I enabled NUMA support & NUMA emulation support in the kernel? |

You should add this link "http://gentoo-wiki.com/HARDWARE_rt2500_on_AMD64" in the section for getting ralink working.
And this lines for getting wpa to work:
ifconfig ra0 up
iwconfig ra0 channel 0
iwpriv ra0 set SSID=Gallien
iwpriv ra0 set NetworkType=Infra
iwpriv ra0 set AuthMode=WPAPSK
iwpriv ra0 set EncrypType=TKIP
iwpriv ra0 set WPAPSK=passphrase
dhcpcd ra0
If I had found this in the FAQ, I would have got my network to work in 10 min instead of 5 hourse |
