I've put together an update for flash-kernel that handles booting an uncompressed image (to support existing arm64 installs), a self- compressed image (to support existing armhf installs), and a gzip'd image (to support the proposed format). It assumes the kernel is called "vmlinuz" in all cases (because that's currently the case, and I presume will continue to be the case in future).
Just finishing up testing today, but I've already confirmed it works on pi2, pi3, and pi3+ with all (supported) kernel cases - just cm3 and cm3+ to go. The update also switches the pi2 case to using the same boot- script as all the rest. I'll ping Lukasz for a review when everything's confirmed as working. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-raspi2 in Ubuntu. https://bugs.launchpad.net/bugs/1808056 Title: vmlinuz is very large in arm64 -raspi2 Status in flash-kernel package in Ubuntu: Confirmed Status in linux-raspi2 package in Ubuntu: Triaged Bug description: The debs are close to the same size: mwhudson@ringil:~/Downloads$ ls -l linux-image-4.15.0-1030-raspi2_4.15.0-1030.32_arm64.deb -rw-rw-r-- 1 mwhudson mwhudson 5398652 Dec 12 10:42 linux-image-4.15.0-1030-raspi2_4.15.0-1030.32_arm64.deb mwhudson@ringil:~/Downloads$ ls -l linux-image-4.15.0-1030-raspi2_4.15.0-1030.32_armhf.deb -rw-rw-r-- 1 mwhudson mwhudson 6640960 Dec 12 10:42 linux-image-4.15.0-1030-raspi2_4.15.0-1030.32_armhf.deb But the vmlinuz on arm64 is several times larger: $ dpkg-deb -c linux-image-4.15.0-1030-raspi2_4.15.0-1030.32_armhf.deb -rw------- root/root 6633048 2018-12-07 06:38 ./boot/vmlinuz-4.15.0-1030-raspi2 $ dpkg-deb -c linux-image-4.15.0-1030-raspi2_4.15.0-1030.32_arm64.deb -rw------- root/root 23914504 2018-12-07 06:38 ./boot/vmlinuz-4.15.0-1030-raspi2 This forced us to make the boot partition larger for the raspi3 b+ arm64 image we made.
