selftests/powerpc: Give all tests 2 minutes timeout

2024-11-07T11:36:30Z

Each of the powerpc selftests runs with a timeout of 2 minutes by default (see tools/testing/selftests/powerpc/harness.c). But when tests are run with run_kselftest.sh it uses a timeout of 45 seconds, meaning some tests run OK standalone but fail when run with the test runner. So tell run_kselftest.sh to give each test 130 seconds, that should allow the tests to complete, or be killed by the powerpc test harness after 2 minutes. If for some reason the harness fails, or for the few tests that don't use the harness, the 130 second timeout should catch them if they get stuck.

selftests/powerpc: make sub-folders buildable on their own

2024-04-29T13:54:42Z

Build breaks when executing make with run_tests for sub-folders under powerpc. This is because, CFLAGS and GIT_VERSION macros are defined in Makefile of toplevel powerpc folder. make: Entering directory '/home/maddy/linux/tools/testing/selftests/powerpc/mm' gcc hugetlb_vs_thp_test.c ../harness.c ../utils.c -o /home/maddy/selftest_output//hugetlb_vs_thp_test hugetlb_vs_thp_test.c:6:10: fatal error: utils.h: No such file or directory 6 | #include "utils.h" | ^~~~~~~~~ compilation terminated. Fix this by adding the flags.mk in each sub-folder Makefile. Also remove the CFLAGS and GIT_VERSION macros from powerpc/ folder Makefile since the same is definied in flags.mk Signed-off-by: Madhavan Srinivasan Signed-off-by: Michael Ellerman Link: https://msgid.link/20240229093711.581230-3-maddy@linux.ibm.com

selftests/powerpc: Re-order *FLAGS to follow lib.mk

2024-04-29T13:51:16Z

In some powerpc/ sub-folder Makefiles, CFLAGS are defined before lib.mk include. Clean it up by re-ordering the flags to follow after the mk include. This is needed to support sub-folders in powerpc/ buildable on its own.

selftests/powerpc: Add automatically allocating read_file

2023-02-09T12:56:45Z

A couple of tests roll their own auto-allocating file read logic. Add a generic implementation and convert them to use it. Signed-off-by: Benjamin Gray Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/20230203003947.38033-6-bgray@linux.ibm.com

selftests/powerpc: Add generic read/write file util

2023-02-09T12:56:45Z

File read/write is reimplemented in about 5 different ways in the various PowerPC selftests. This indicates it should be a common util. Add a common read_file / write_file implementation and convert users to it where (easily) possible.

selftests/powerpc: Use req_max_processed_len from sysfs NX capabilities

2021-06-25T04:47:19Z

On PowerVM, the hypervisor defines the maximum buffer length for each NX request and the kernel exported this value via sysfs. This patch reads this value if the sysfs entry is available and is used to limit the request length.

selftests/powerpc: Use proper error code to check fault address

2020-07-15T13:10:17Z

ERR_NX_TRANSLATION(CSB.CC=5) is for internal to VAS for fault handling and should not used by OS. ERR_NX_AT_FAULT(CSB.CC=250) is the proper error code should be reported by OS when NX encounters address translation failure. This patch uses CC=250 to determine the fault address when the request is not successful.
