Talk:Raspberry Pi 3 64 bit Install

dev-vcs/git segfaults on commit with specified CFLAGS
See https://bugs.gentoo.org/662260. Replacing "-march=armv8-a+crc -mtune=cortex-a53" with "-march=native" (or removing it) produced a working git. Otherwise, most any operation beyond cloning a repo would cause a segfault.

binutils
Hint: binutils-2.30 fails with https://sourceware.org/bugzilla/show_bug.cgi?id=22764, binutils-2.29.1 works

Hmm. It seems to work for me. Its in my armv8a binhost at http://bloodnoc.org/~roy/BINHOSTS/gcc-7.x/armv8a/sys-devel/

Feel free to try it. An ebuild may not get a version bump if its changed from not working to working on a single arch. That would cause useless rebuilds for everyone already using it succesfully.

The comment 15 on that bug cvs-commit@gcc.gnu.org 2018-02-05 18:34:02 UTC, says it was fixed. Update your portage repository and try again.

Add Simple FB
[*] Simple framebuffer support

This gets console messages until the VC4 starts.

Conversely, it appears to hang if the VC4 fails to start.

Host Virtualisation Support
libvirtd supports KVM on arm64 now. On the Pi, its probably only a toy but theres a challenge.

On the host, prepare to support arm64 guests.

[*] Virtualization ---> │ │          --- Virtualization                                                               │ │ │ │          [*]   Kernel-based Virtual Machine (KVM) support                                 │ │ │ │             Host kernel accelerator for virtio net                                     │ │ │ │          [ ]   Cross-endian support for vhost (NEW)

Guest Paravirtualisation Support
Turn on Paravirtualisation and all the virtio drivers

(exactly what is TBD)

brcmfmac43430-sdio.txt not available
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/brcm don't have brcmfmac43430-sdio.txt. But brcmfmac43430-sdio.AP6212.txt and brcmfmac43430-sdio.MUR1DX.txt are found.

Do they replace brcmfmac43430-sdio.txt?

When I replace brcmfmac43430-sdio.txt with AP6212 and MUR1DX I don't see any change in dmesg.

 * AFIK the linux-firmware repo never distributed the brcmfmac43430 NVRAM file. You may not see any difference in dmesg, but there are differences in the two files. The Raspbian one includes improved BT coexistence when WiFi is enabled. You should use the Raspbian one since it is the official and supported Raspberry Pi distribution.

/dev/serial1 for btattach service
Wouldn't it be more prudent to use /dev/serial1 instead of /dev/ttyAMA0 in /etc/init.d/btattach script?

Raspberry Pi Firmware github master branch doesn't boot with 5.10
should be changed to

Otherwise the device won't boot. I don't know if this is specific to 5.10 or maybe it was just my build, but I could not get past a black screen or a rainbow screen when using boot files from the master branch. Switching to the stable branch fixes this issue.
