I verified with both trees and didn't notice any issues with my
VisionFive board, so I don't really understand why BeagleV Starlight
shows a different behavior.
For reference, please see [3] which contains all required patches
applied on top of next-20231117. The top-most one 9d36dec7e6da ("riscv:
dts: starfive: Add JH7100 MMC nodes") is optional, I added it to extend
a bit the test suite (SD-card card access also works fine).
[3]: https://gitlab.collabora.com/cristicc/linux-next/-/tree/visionfive-eth
For configuring the kernel, I used:
$ make [...] defconfig
$ scripts/config --enable CONFIG_NONPORTABLE --enable ERRATA_STARFIVE_JH7100
I also noticed a warning message right before building starts, but it
doesn't seem to be harmful:
WARNING: unmet direct dependencies detected for DMA_GLOBAL_POOL
Depends on [n]: !ARCH_HAS_DMA_SET_UNCACHED [=n] && !DMA_DIRECT_REMAP [=y]
Selected by [y]:
- ERRATA_STARFIVE_JH7100 [=y] && ARCH_STARFIVE [=y] && NONPORTABLE [=y]
Thanks,
Cristian
