orion777,
There are no stupid questions.
The shell that you get when you ssh into a system is closed when you log out.
You need screen or tmux. I use screen.
ssh to the system.
emerge screen
Run screen.
Start your compile.
Close your terminal
Log in again, from anywhere.
Run to reattach to your compile session.

However, I cant understand:
1) how do we get .config? I cant understand how to generate .config if there are no any config files?
1.1)what are the differences between generated .config and this https://github.com/sakaki-/bcmrpi3-kernel/blob/master/config ?
2) What actually do command make bcmrpi3_defconfig ? Why we have to specify exactly bcmrpi3_defconfig, what does its means? |

Thank You! I found this explanation:
to detaching screen: CTRL+A and CTRL+D
to reattach to screen: screen -r
So what is the correct one: simply close or ctrl+a and than ctrl+d? And screen -x or screen -r? |

orion777,
They are all correct.
reattaches to a running screen session if there is only one.
demands the process ID of the screen session you want to reattach to.
Consider the following command sequence ..
| Code: | screen
Ctrl-A,D
screen
Ctrl-A,D |
You now have two screen sessions running and are detached from them both.

The make bcmrpi3_defconfig command creates a default .config file, using the recommended baseline settings for the RPi3 in 64bit (you can see it in the kernel source tree here). You can of course modify the resulting .config as you wish.
The .config used in the automatically built bcmrpi3-kernel is almost exactly the vanilla bcmrpi3_defconfig version: as stated in its README:
| Quote: | | Builds are performed with the standard bcmrpi3_defconfig, with the only change being that the first 12 hex digits of the tip commit SHA1 hash are appended to CONFIG_LOCALVERSION (with a separating hyphen) before building. |
Note though, that the bcmrpi3-kernel tracks the 4.9 branch not the 4.10 branch by default. The 4.9 branch gets most of the backport attention, but is currently missing certain drivers, most notably HDMI audio support.
In any event, now you have a booting kernel, you can go back in an try a "make menuconfig" if you like, to create your own custom .config from the baseline. Just remember to backup your working kernel and .config before you do ^-^

MC working fine.
usb_modeswitch seems working as cellular modem is working.
However, dmesg reports failure in cpu speed operation:

Is it necessary to disable genup schedule if I work with custom kernel, packages, etc? |

No, if you like you can leave it scheduled, to keep the rest of your system up-to-date. Anything custom you add (packages etc.) will also be updated whenever genup runs, if new versions become available in the Gentoo tree, but these will be built locally (as they won't be present on the isshoni.org binhost).
One thing you will need to do however is to disable the binary kernel updates. To do so, edit /etc/portage/package.use/rpi3-64bit-meta, and add the following as the only uncommented line at the end: | Code: | | dev-embedded/rpi3-64bit-meta -kernel-bin |
Then as root, issue: | Code: | | pi64 ~ # emerge -av dev-embedded/rpi3-64bit-meta |
That will prevent your custom kernel being overwritten when genup triggers.

orion777,
That error says that something cannot change the Pi CPU frequency.
Which kernel are you using?
What do you have in the Pis /boot/config.txt?
That guide works for me with | Code: | Pi3_64 ~ # uname -a
Linux Pi3_64 4.10.17-v8+ #7 SMP PREEMPT Mon Oct 9 16:31:01 BST 2017 aarch64 GNU/Linux |

orion777,
That looks OK.
Pastebin your kernel .config file.
I'll compare it with mine ... or you can. My .config

Seems that everything is here:
Your is not configured, my is Y
CONFIG_CPU_FREQ_DEFAULT_GOV_POWERSAVE=y
Your is Y,my is not configured
CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND is not set
https://paste.pound-python.org/show/ber5E3vZY2VlgcQoxqLk/
Seems that it is necessary to enter into Default CPUFreq governor (powersave) ---> and to set ONDEMAND, not POWERSAVE. However, I was following illustration only and this subsetting was not set.
https://wiki.gentoo.org/wiki/Raspberry_Pi_3_64_bit_Install#Configure_The_Kernel
Kernel is remaked and seems it works (at least, there are no more errors in dmesg). Is it possible to check does it really work and CPU freq is adjusted? Or I can check radiator heating only?
Also there are some errors in dmesg, but I dont understand are thay critical or not.. I will post them here just to know (I have very little experience in gentoo and also in linux)

CONFIG_CPU_FREQ_DEFAULT_GOV_POWERSAVE=y
Your is Y,my is not configured
CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND is not set |
You may have at most one CONFIG_CPU_FREQ_DEFAULT_GOV. That's the one that the kernel uses at startup.
Its possible to switch to another governor at boot, with a kernel parameter, or at any time.
However, the POWERSAVE governor forces the Pi to run at 600MHz. If you want to change that, you must firs select a different CPU governor.
| Code: | | [ 0.000000] Failed to get local register map. FIQ is disabled for cpus > 1 |
I get that, so its probably harmless.
The others I will need to reboot for, which is not ideal right now.

All,
in the latest weekly autobuild, just pushed to isshoni.org, gcc-7.2.0 has been released. I've switched to this as the default compiler for the 64-bit RPi3 (replacing gcc-6.4.0), but binary packages for both versions of gcc are available on the binhost (for now).
Be aware that the libtool binary package on the binhost was built with gcc-7.2.0 (you should really rebuild libtool locally when upgrading gcc, but I pushed a new version in case anyone upgrades without checking).
Please let me know if you experience any problems with it.

Good evening!
I'm a little bit confusing about network configuration..
The sakakis' image contains installed:
1) at least two network managers:
- net-misc/netifrc 0.5.1
- net-misc/networkmanager 1.8.4
2) at least two dhcp clients:
- net-misc/dhcp 4.3.6-r1
- net-misc/dhcpcd 7.0.0 rc3
The emerge --depclean reports that BOTH dhcp and dhcpcd are required for NetworkManager. Both simultaneously??
As dhcp operation ignore configuration in /etc/dhcpcd.conf , I suppose that net-misc/dhcp is general dhcp client. I was trying to uninstall net-misc/dhcp by running emerge -C but DHCP still is possible to assign IP for the network card, however, configurations in /etc/dhcpcd.conf are NOT ignored.
So, actually, how it works?
(I'm trying to detect multiple huawei 3372h, but this image obtain IP by dhcp only for the first one; while I have another gentoo 64 which is capable to detect IPs for three huawei simultaneously; thats why I'm worry about networking in this image)
Thank you. |

orion777,
the gentoo-on-rpi3-64bit image uses NetworkManager by default. If you look at the shipped USE-flag configuration ("eix -I NetworkManager") you'll see that dhclient is set, and dhcpcd unset. The dhclient USE flag sets up the dependency on net-misc/dhcp (see the ebuild) and also sets the dhclient configure option, which in turn sets "NM_CONFIG_DEFAULT_MAIN_DHCP='dhclient'" at build-time.
So by default, NetworkManager is going to try to use dhclient to resolve DHCP. You can modify this of course; "man 5 networkmanager.conf" yields: | Code: | dhcp
This key sets up what DHCP client NetworkManager will use. Allowed
values are dhclient, dhcpcd, and internal. The dhclient and dhcpcd
options require the indicated clients to be installed. The internal
option uses a built-in DHCP client which is not currently as
featureful as the external clients.
If this key is missing, it defaults to internal. It the chosen
plugin is not available, clients are looked for in this order:
dhclient, dhcpcd, internal. |
Not sure why you are getting a dependency on dhcpcd though, since that USE flag is not set for NetworkManager. I shipped the package as part of the image for those who want to roll their own networking, but it isn't enabled by default (run "rc-update show -v" to verify this).
Also, NetworkManager should be able to support multiple WiFi adaptors (although I haven't tested this on the Pi). Make sure you have sufficient power supply. You can always setup wlan1, wlan2 etc. yourself, by adding them to NetworkManager's unmanaged interfaces, and then creating your own connections (using wpa_supplicant (bundled) and whichever DHCP client you wish).

Ou, that is my fault: I was trying to emegre previous version, after that I was emegre actual, but I forgot to take a look into USE flags.. by default, network manager is installed WITH dhcpcd flag :/ So that is my fault, sorry..

Mine are NDIS virtual eth interfaces.
So, if I discard them from the NetworkManager managed hosts, than I have to use /etc/conf.d/net as is shown here? https://wiki.gentoo.org/wiki/Handbook:X86/Full/Networking |

Hello,
I'm trying to compile some packages trough chrooted env with qemu using your .img but something goes wrong.
Here is what i've done :
| Code: | abyss rpithpc # cat ../qemu-wrapper-rpi3.c
#include <string.h>
#include <unistd.h>
int main(int argc, char **argv, char **envp) {
char *newargv[argc + 3];
newargv[0] = argv[0];
newargv[1] = "-cpu";
newargv[2] = "cortex-a53"; /* here you can set the cpu you are building for */
memcpy(&newargv[3], &argv[1], sizeof(*argv) * (argc -1));
newargv[argc + 2] = NULL;
return execve("/usr/bin/qemu-aarch64", newargv, envp);
}
abyss rpithpc # ls -al usr/bin/qemu-aarch64
-rwxr-xr-x 1 root root 3450392 déc. 4 14:16 usr/bin/qemu-aarch64
abyss rpithpc # gcc -static ../qemu-wrapper-rpi3.c -O3 -s -o opt/qemu-arm-rpi/qemu-wrapper
abyss rpithpc # echo ':aarch64:M::\x7fELF\x02\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\xb7:\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xfe\xff\xff:/opt/qemu-arm-rpi/qemu-wrapper:' > /proc/sys/fs/binfmt_misc/register |
Kind of error i got while compiling :
| Code: | gcc-config: error: could not run/locate 'aarch64-unknown-linux-gnu-gcc'
[...]
checking whether the C compiler works... no
configure: error: in `/var/tmp/portage/dev-lang/python-2.7.14-r1/work/aarch64-unknown-linux-gnu': |
Indeed :
| Code: | abyss / # aarch64-unknown-linux-gnu-gcc
bash: /usr/aarch64-unknown-linux-gnu/gcc-bin/6.4.0/aarch64-unknown-linux-gnu-gcc: cannot execute binary file: Exec format error
|
I think there is something wrong with my wrapper, but don't see what  |

Make the binpkg :
| Code: | quickpkg app-emulation/qemu
|
Run within the root folder of the chrooted env :
| Code: | | ROOT=$PWD/ emerge --usepkgonly --oneshot --nodeps qemu |

takhisis_astrafall,
That says that static-user* is a new USE. You must build app-emulation/qemu with USE=static-user before you put it into the arm64 chroot.
Inside the chroot it will be the only program capable of running on the host. It cannot call libraries as all the libs inside the chroot are arm64.
Rebuild app-emulation/qemu and move it to the chroot again.

Mea Culpa Neddyseagoon,
My qemu was rebuild between the package creation and when i made "emerge -pv qemu" in my previous post
Here is what was installed :
| Code: |
abyss rpithpc # ROOT=$PWD/ emerge --usepkgonly --oneshot --nodeps -pv qemu
These are the packages that would be merged, in order:
[binary R ] app-emulation/qemu-2.10.1::gentoo to /mnt/experiment/rpi/rpithpc/ USE="aio alsa bzip2 caps curl fdt filecaps gnutls jpeg ncurses nfs nls opengl pin-upstream-blobs png python sasl sdl seccomp ssh static-user usb vde vhost-net vnc xattr -accessibility -bluetooth -debug -glusterfs -gtk -gtk2 -infiniband -iscsi -lzo -numa -pulseaudio -rbd -sdl2 (-selinux) -smartcard -snappy -spice -static -systemtap -tci {-test} -usbredir -virgl -virtfs -vte -xen -xfs" LINGUAS="-bg -de_DE -fr_FR -hu -it -tr -zh_CN" PYTHON_TARGETS="python2_7" QEMU_SOFTMMU_TARGETS="aarch64 arm -alpha -cris -i386 -lm32 -m68k -microblaze -microblazeel -mips -mips64 -mips64el -mipsel -moxie -nios2 -or1k -ppc -ppc64 -ppcemb -s390x -sh4 -sh4eb -sparc -sparc64 -tricore -unicore32 -x86_64 -xtensa -xtensaeb" QEMU_USER_TARGETS="aarch64 arm -alpha -armeb -cris -hppa -i386 -m68k -microblaze -microblazeel -mips -mips64 -mips64el -mipsel -mipsn32 -mipsn32el -nios2 -or1k -ppc -ppc64 -ppc64abi32 -ppc64le -s390x -sh4 -sh4eb -sparc -sparc32plus -sparc64 -tilegx -x86_64" 0 KiB

takhisis_astrafall,
That's all correct then.
What does | Code: | | $ lddtree <chroot>/usr/bin/qemu-aarch64 |
show?
The static build will return (interpreter => None)
Does your running kernel have CONFIG_BINFMT_MISC=y set?
Is the binfmt service in the default runlevel?

Neddyseagoon,
It seems that all is good
| Code: | abyss rpithpc # lddtree usr/bin/qemu-aarch64
usr/bin/qemu-aarch64 (interpreter => None)
abyss rpithpc # /etc/init.d/binfmt status
* status: started
abyss rpithpc # ls -al /proc/sys/fs/binfmt_misc/
total 0
drwxr-xr-x 2 root root 0 déc. 4 16:29 .
dr-xr-xr-x 1 root root 0 déc. 4 16:29 ..
-rw-r--r-- 1 root root 0 déc. 4 17:06 aarch64
--w------- 1 root root 0 déc. 4 17:06 register
-rw-r--r-- 1 root root 0 déc. 4 16:29 status |
Edit :
Nevermind,
It was my wrapper,
Modified | Code: | | newargv[2] = "cortex-a53"; |
by | Code: | | newargv[2] = "cortex-a8"; |
and it's working.
