Title:
PolarFire Icicle Kit: L2 Cache wrong interrupts in devicetree
Status in linux-riscv package in Ubuntu:
Fix Released
Bug description:
[Impact]
The 5.19 kernel contains support for the PolarFire Icicle board. But
booting with linux-image-5.19.0-1002-generic_5.19.0-1002.2_riscv64.deb
fails.
The cause is that the device-tree incorrectly specifies the PLIC
interrupts used for the drivers/soc/sifive/sifive_l2_cache.c.
A patch is available as
https://lore.kernel.org/all/20220817132521.3159388-1-heinrich.schucha...@canonical.com/
[PATCH 1/1] riscv: dts: microchip: correct L2 cache interrupts
This patch only changes the device-tree of the PolarFire Icicle Kit.
Please, add the patch to the 5.19 and future kernels.
[Test Plan]
Use the SiFive Unmatched preinstalled image and install the 5.19
kernel. Try to boot on the Polarfire Icicle board.
[Where problems could occur]
The fix only concerns a board which has been unsupported by Ubuntu
yet.
In case of an incorrect fix the board might not boot or otherwise
malfunction.
