KVM/QEMU Raspberry Pi

Linux-haladó

Üdv!

Fedora 22 x64-en szeretném az RPi-t elndítani:

~# sudo qemu-system-arm -kernel kernel-qemu -cpu arm1176 -m 256 -M versatilepb -no-reboot -serial stdio -append "root=/dev/sda2 panic=1" -hda 2015-05-05-raspbian-wheezy.img -net nic -net user -vnc :0 -net tap,ifname=vnet0,script=no,downscript=no

Ahogy fent látszódik, szépen indul is, belépek 'pi' userrel, de ki is dob. Mit lehet a gondja?
Mit rontok el?

A virtmanager-be is be lehet valahogy tenni? Csak azért, mert ott elegánsabb lenne. :)

5) Patch Raspbian Image for QEMU

Use nano, to open the following file for edit:

nano /etc/ld.so.preload

- Comment out the first line by putting a # in front of it:

#/usr/lib/arm-linux-gnueabihf/libcofi_rpi.so

Igen, valóban kellett valamit trükközni, csak nem tudok így bebootolni:

~$ sudo qemu-system-arm -kernel kernel-qemu -cpu arm1176 -m 256 -M versatilepb -no-reboot -serial stdio -append "root=/dev/sda2 panic=1 rootfstype=ext4 rw init=/bin/bash" -hda 2015-05-05-raspbian-wheezy.img -net nic -net user -vnc :0 -net tap,ifname=vnet0,script=no,downscript=no

...és itt megáll.

:(

Megvan, ez az első login:

sudo qemu-system-arm -kernel kernel-qemu -cpu arm1176 -m 256 -M versatilepb -no-reboot -serial stdio -append "root=/dev/sda2 panic=1 rootfstype=ext4 rw init=/bin/bash" -hda 2015-05-05-raspbian-wheezy.img

:)

Utána jöhet:

nano /etc/ld.so.preload
#/usr/lib/arm-linux-gnueabihf/libcofi_rpi.so

reboot

A Pidora (Fedora 20 Remix) próbálom beizzítani, Első indításkor a grafikus beállító megy is, restart után megint jó az első login, de ezután már nem jó, belefagy.
Megpróbáltam újból Text bázisú boot móddal. Ha indítok egy startx-et a logban egy hibát látok (open /dev/dri/card0: No such file or directory):

Az /etc/X11/xorg.conf-ba ezt próbáltam csak:

SubSection "Display"
Depth 16
Modes "800x600"
EndSubSection
EndSection

Szóval qemu-ban mivel lehet xorg-ot használni Pidora esetén?

( uid_6201 v | 2015. 08. 09., v – 08:46 )

Egy ide kapcsolódó kérdés foglalkoztat: miért jó architektúra emulációval elindítani az eredeti Rpi2 lapka helyett?
Hátrány: az architektúra emuláció költséges, szerintem kb. 5..10-szeres CPU teljesítményt igényel egy másik architektúra emulálása. Ennek az aránynak a kimérésére egyúttal megkérlek.

Tömörítési CPU teszteket lásd itt: http://hup.hu/node/141808
--> natív x86-os tömörítési tempó mérés (amikor még nincs elindítva qemu)
--> emulált Rpi-ben tömörítési tempó mérés

További hátrány: emuláció során nem kapom meg a GPIO lábakat.
