error excuting spike #230

Closed awxhw closed 6 years ago

awxhw commented 6 years ago

when excuted a sample test by using command spike pk test，but the error happened is as follows. " terminate called after throwing an instance of 'std::runtime_error' what(): couldn't allocate 2147483648 bytes of target memory Aborted (core dumped)

"

And when excuted spike alone, the same error occurred, so I'm not sure about that.

Qemu works much better than spike+pk, and is much better supported than spike+pk. You should use qemu instead.

Also, if you are using riscv-tools, then you are using old unmaintained and unsupported tools. Use riscv-gnu-toolchain instead.

Looks like your host machine doesn't have enough memory. Spike tries to allocate 2 GiB by default. Try to explicitly run Spike with less memory, e.g.:

spike -m128 pk test

@jim-wilson Thank you for your reply, I will use riscv-gnu-toolchain instead.

@heshamelmatary Thanks, the problem has been resolved by running spike -m128 pk test, as the total memory of my virtual machine is only 2GiB.

@heshamelmatary when I run Spike to boot linux using the following command: $spike -m256 bbl riscv-tools/riscv-linux/vmlinux

Howerver, no boot log can be seen until I hit ctrl+C，the logs are as follow, ^C: core 0: 0xffffffe00009137c (0x10016073) csrsi sstatus, 2 : core 0: 0xffffffe000091380 (0x00006422) ld s0, 8(sp) : core 0: 0xffffffe000091382 (0x00000141) addi sp, sp, 16 : core 0: 0xffffffe000091384 (0x00008082) ret : core 0: 0xffffffe0000b3cde (0x100027f3) csrr a5, sstatus : core 0: 0xffffffe0000b3ce2 (0x00008b89) andi a5, a5, 2 : core 0: 0xffffffe0000b3ce4 (0x0000c3a9) beqz a5, pc + 66 : core 0: 0xffffffe0000b3ce6 (0x432230ef) jal pc + 0x23432 : core 0: 0xffffffe0000d7118 (0x00001141) addi sp, sp, -16 : core 0: 0xffffffe0000d711a (0x0000e422) sd s0, 8(sp)

Is there anything wrong with that?

@awxhw Sorry, I don't have experience running Linux on Spike, I only tried it recently on QEMU

awxhw commented 6 years ago

@heshamelmatary Ok， thanks.

sifive/freedom-u-sdk has working support to build a linux kernel+buildroot and boot it on qemu and spike. Though the default serial driver doesn't work with spike, so you need to enable CONFIG_HVC_RISCV_SBI in conf/linux_defconfig to make that work. It is just "make qemu" for a qemu boot and "make sim" for a spike boot.
