Package: linux
Version: 6.12.86-1
Severity: important
Dear Maintainer,
The riscv64 kernel is built with CONFIG_NR_CPUS=64. On hardware with more than
64 harts, the excess CPUs are silently lost at boot.
Hardware:
Board: SpacemiT V100 (C2201MB1)
Vendor: SpacemiT (mvendorid=0x710)
marchid: 0x8000000058000002
mimpid: 0x4c4d900
Arch: riscv64, MMU sv48
ISA: rv64imafdcvh_zicbom_zicboz_zicntr_zicond_zicsr_zifencei
_zihintntl_zihintpause_zihpm_zimop_zawrs_zfa_zfh_zfhmin
_zca_zcb_zcd_zcmop_zba_zbb_zbc_zbs_zkt_zvbb_zvbc_zve32f
_zve32x_zve64d_zve64f_zve64x_zvfh_zvfhmin_zvkb_zvkg
_zvkned_zvknhb_zvksed_zvksh_zvkt_smaia_smstateen_ssaia
_sscofpmf_sstc_svinval_svnapot_svpbmt
Physical harts: 80 (hart IDs 0-39, 64-87)
Observed behaviour:
$ nproc --all
64
$ cat /sys/devices/system/cpu/possible
0-63
16 harts are silently dropped at boot. The kernel only sees 64 CPUs.
Boot messages:
[ 0.000000] NR_CPUS is too small for the number of ACPI tables.
This message is repeated 16 times.
Kernel config:
CONFIG_SMP=y
CONFIG_NR_CPUS=64
Expected behaviour:
All 80 harts should be usable. CONFIG_NR_CPUS should be raised to at least
256 for riscv64, matching the arm64 default.
Suggested fix:
In debian/config/riscv64/config, change:
CONFIG_NR_CPUS=64
to:
CONFIG_NR_CPUS=256
Workaround:
None without recompiling the kernel.
Thanks,
Lufei
