https://git.0xinfinity.dev/distro/kernel.git/atom?h=linux-5.0.y2018-06-03T14:39:14Zpowerpc/sstep: Fix emulate_step test if VSX not present2018-06-03T14:39:14ZRavi Bangoria2018-05-21T04:21:08Zurn:sha1:5a61640e322693028a36452f637681d388e4c241
emulate_step() tests are failing if VSX is not supported or disabled.
emulate_step_test: lxvd2x : FAIL
emulate_step_test: stxvd2x : FAIL
If !CPU_FTR_VSX, emulate_step() failure is expected and testcase should
PASS with a valid justification. After patch:
emulate_step_test: lxvd2x : PASS (!CPU_FTR_VSX)
emulate_step_test: stxvd2x : PASS (!CPU_FTR_VSX)

powerpc: emulate_step() tests for load/store instructions2017-03-03T00:24:50ZRavi Bangoria2017-02-14T09:16:43Zurn:sha1:4ceae137bdab2232e57b2e6fd5631a22a0160938
Add new selftest that test emulate_step for Normal, Floating Point,
Vector and Vector Scalar - load/store instructions. Test should run
at boot time if CONFIG_KPROBES_SANITY_TEST and CONFIG_PPC64 is set.
Sample log:
emulate_step_test: ld : PASS
emulate_step_test: lwz : PASS
emulate_step_test: lwzx : PASS
emulate_step_test: std : PASS
emulate_step_test: ldarx / stdcx. : PASS
emulate_step_test: lfsx : PASS
emulate_step_test: stfsx : PASS
emulate_step_test: lfdx : PASS
emulate_step_test: stfdx : PASS
emulate_step_test: lvx : PASS
emulate_step_test: stvx : PASS
emulate_step_test: lxvd2x : PASS
emulate_step_test: stxvd2x : PASS
