ec6347bb - x86, powerpc: Rename memcpy_mcsafe() to copy_mc_to_{user, kernel}()

Tue, 06 Oct 2020 03:40:16 +0000

x86, powerpc: Rename memcpy_mcsafe() to copy_mc_to_{user, kernel}()In reaction to a proposal to introduce a memcpy_mcsafe_fast()implementation Linus points out that memcpy_mcsafe() is poorly namedrelative to communicating the scope of the interface. Specifically whataddresses are valid to pass as source, destination, and what faults /exceptions are handled.Of particular concern is that even though x86 might be able to handlethe semantics of copy_mc_to_user() with its common copy_user_generic()implementation other archs likely need / want an explicit path for thiscase: On Fri, May 1, 2020 at 11:28 AM Linus Torvalds wrote: > > On Thu, Apr 30, 2020 at 6:21 PM Dan Williams wrote: > > > > However now I see that copy_user_generic() works for the wrong reason. > > It works because the exception on the source address due to poison > > looks no different than a write fault on the user address to the > > caller, it's still just a short copy.

It is usedas the slow / careful backend that is supplanted by a fastcopy_mc_generic() in a follow-on patch.One side-effect of this reorganization is that separating copy_mc_64.Sto its own file means that perf no longer needs to track dependenciesfor its memcpy_64.S benchmarks.

selftests/powerpc/64: Test exception cases in copy_tofrom_userThis adds a set of test cases to test the behaviour ofcopy_tofrom_user when exceptions are encountered accessing thesource or destination. Currently, copy_tofrom_user does not alwayscopy as many bytes as possible when an exception occurs on a storeto the destination, and that is reflected in failures in these tests.Based on a test program from Anton Blanchard.[paulus@ozlabs.org - test all three paths, wrote commit description, made EX_TABLE create an exception table.]Signed-off-by: Paul Mackerras Signed-off-by: Michael Ellerman List of files: /linux-6.15/tools/testing/selftests/powerpc/copyloops/.gitignore

Fri, 03 Aug 2018 10:13:04 +0000

selftests/powerpc/64: Test all paths through copy routinesThe hand-coded assembler 64-bit copy routines include feature sectionsthat select one code path or another depending on which CPU we areexecuting on. The self-tests for these copy routines end up testingjust one path. This adds a mechanism for selecting any desired codepath at compile time, and makes 2 or 3 versions of each test, eachusing a different code path, so as to cover all the possible paths.Signed-off-by: Paul Mackerras [mpe: Add -mcpu=power4 to CFLAGS for older compilers]Signed-off-by: Michael Ellerman List of files: /linux-6.15/tools/testing/selftests/powerpc/copyloops/.gitignore
