https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D243118 Bug ID: 243118 Summary: sysutils/rpi-firmware: rpi4 updates for rpi3-psci-monitor severely slows down booting on 3B+ Product: Ports & Packages Version: Latest Hardware: arm64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: ports-bugs@FreeBSD.org Reporter: tom.ty89@gmail.com Created attachment 210471 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D210471&action= =3Dedit test set of rpi3-psci-monitor sources and binaries Booting on a Raspberry Pi 3B+ is extremely slow (could take 30-40 minutes) before the kernel kicks in. Here's the situation: - `12.1-RELEASE` works fine - `12.1-STABLE` / `13.0-CURRENT` snapshots (since at least / as of `2019122= 6`) are broken It is caused by armstub8.bin updates and I've done some dissecting. The differences between the one in 12.1-RELEASE (2b8890a) and the one in the snapshots (6bfbaff) are: - new LOCAL_CONTROL and LOCAL_PRESCALER - new OSC_FREQ - L2 read/write cache latency setting Either of the first two changes alone can slow down booting to different severity at different point. Combining them would make booting intolerably slow. The third change doesn't seem to be problematic so far. Attached is a set of rpi3-psci-monitor sources and binaries I built with gcc-arm-9.2-2019.12-aarch64-aarch64-none-elf from https://developer.arm.com/tools-and-software/open-source-software/developer= -tools/gnu-toolchain/gnu-a/downloads: - rpi3-psci-monitor-2b8890a is equivalent to the one in 12.1-RELEASE - rpi3-psci-monitor-6bfbaff is equivalent to the one in the snapshots - rpi3-psci-monitor-2b8890a-{a,b} can show that either of the new values of LOCAL_CONTROL and LOCAL_PRESCALER or OSC_FREQ could slow down booting / tim= e to different severity at different point - rpi3-psci-monitor-6bfbaff-c can show that L2 read/write cache latency setting, the only remaining difference of the armstub8.bin in 12.1-RELEASE = and the one in the snapshots, is not the cause of the issue; although this does= not mean it will not be potentially problematic on other aspects if done "generally". I've already created PRs on https://github.com/gonzoua/rpi3-psci-monitor/pu= ll/6 and https://github.com/raspberrypi/tools/pull/105. (@kevans91, the armstub8.bin you sent me is the one in 12.1-RELEASE with the first two changes) --- Comment #1 from Bugzilla Automation <bugzilla@FreeBSD.org> --- Maintainer informed via mail --=20 You are receiving this mail because: You are the assignee for the bug.=
