[PATCH 1/1] riscv: alloc space exhausted
When trying to run qemu-riscv64_smode_defconfig with 32 harts booting fails. The debug UART shows a message
alloc space exhausted
32 is the current maximum number of harts for machine virt in QEMU 7.0.
Raise the default for SYS_MALLOC_F_LEN to 16 KiB.

Here I ask the same question you asked me some weeks ago: https://lists.denx.de/pipermail/u-boot/2022-March/478742.html
We have all defaults for SYS_MALLOC_F_LEN in /Kconfig. Why should riscv put it somewhere else?

Indeed, it generally should not. There's a few wide-spread exceptions, but this should not be one of them.
