2018-07-20selftests/powerpc: Consolidate copy/paste test logicMichael Ellerman
This logic was shared between multiple tests, but now that we have removed all but one of them we can just move it into that test. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
2018-07-20selftests/powerpc: Remove Power9 paste testsMichael Ellerman
Paste on POWER9 only works to accelerators and not on real memory. So these tests just generate a SIGILL. So just delete them. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Acked-by: Michael Neuling <mikey@neuling.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
2018-07-20selftests/powerpc: Remove Power9 copy_unaligned testMichael Ellerman
This is a test of the ISA 3.0 "copy" instruction. That instruction has an L field, which if set to 1 specifies that "the instruction identifies the beginning of a move group" (pp 858). That's also referred to as "copy first" vs "copy". In ISA 3.0B the copy instruction does not have an L field, and the corresponding bit in the instruction must be set to 1. This test is generating a "copy" instruction, not a "copy first", and so on Power9 (which implements 3.0B), this results in an illegal instruction. So just drop the test entirely. We still have copy_first_unaligned to test the "copy first" behaviour.

Test that an ISA 3.0 compliant machine performing an unaligned copy, copy_first, paste or paste_last is sent a SIGBUS. Signed-off-by: Chris Smart <chris@distroguy.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
