Kselftest pstore test failure on riscv

[vaibhav jadhav]

Hi,

To run the Kselftest pstore test suite I use following:

Hardware: Freedom U540
Architecture: RISCV
Kernel: 5.4.3

Steps followed to run the test:
1.Cloning linux kernel sources from https://github.com/torvalds/linux.git
2.Extracting it.
3.From the cloned kernel source top directory running: # make -C
tools/testing/selftests/ TARGETS=pstore run_tests

Following is the log:
make: Entering directory '/mnt/linux-master/tools/testing/selftests'
make --no-builtin-rules ARCH=riscv -C ../../.. headers_install
make[1]: Entering directory '/mnt/linux-master'
  INSTALL ./usr/include

make[1]: Entering directory '/mnt/linux-master/tools/testing/selftests/pstore'

Trying to find reasons for failue:

# Checking /dev/pmsg0 exists ... FAIL
# Writing unique string to /dev/pmsg0 ... FAIL

Thankyou
